Definitions
- This invention is an improved book binding or covering machine.
- the components or signatures which are to make up the finished pamphlet or other book are supposed to have been gathered or grouped in proper arrangement.
- the loose signature group may be united or bound together in the machine hereof, and the resulting book may then have a cover applied. If the book has been previously bound, this machine may be in part employed to merely cover the same.
- each of the successive signature groups which, for convenience, may be termed books, is caused to travel or advance along a designated path through the machine while clamped or held firmly compacted, and during its travel is operated upon by various mechanisms for performing the individual steps in the binding or covering process.
- Examples of machines of this type are shown in my prior patents Lovell and Bredenberg 476,208 and Bredenberg 1,073,324.
- the present machine also resembles my prior patents in that each book, held in spring closed clamps having facewise openable clamp parts, is conveyed at the first side of the machine to a trimming mechanism and a roughening mechanism, and around the end of the machine to the other side, where it travels to a gluing mechanism, a mechanism for aidplying a fibrous backing strip over the glue and mechanisms for applying an impervious outer backing, which may be the pamphlet cover, and pressing and folding or breaking the cover about the sides of the book.
- T Unlike my prior patents wherein the roughing and gluing operations, but not all of the other operations, proceed while the book is traveling, T herein prefer to follow the well-known plan of having the several mechanisms operable during travel, thus avoiding the delay of thetemporary stoppages otherwise mecessary.
- the ordinary mode of providing for operation 4 during travel is to cause each mechanism, while acting on the book, to partake of the advancing motion; and I do this in some cases by givlng the mechanism a rotary motion tangent to the book as with the glue rollers of my prior patents, or the Lewis Patent No. 551,776, or the staple applying mecha nism of the Crowell Patent No.
- the main objects of the present invention are the general improvement of the efficiency and running qualities of the machine and the particular improvement of the means for feeding the successive books into the clamps, the mechanism for trimming the backs of the signature groups, the mechanism for applying a pervious strip, the mechanism for applying a cover to the book, the mechanism for breaking or bending the cover into place, and the discharge or de livery mechanism.
- Another object, in a binding machine, is to combine with, the other mechanisms a K mechanism which operates upon the book to objects the prior to the application of glue for producing a plurality of shallow cross-cuts or grooves at the back of the book to facilitate the entrance of the adhesive and improve the security of the binding.
- Figure 1 is a general plan View of a bookbinding and covering apparatus embodying the present invention, with many well-known parts and many details omitted for simplicity.
- Figs. 2 to 6 illustrate in detail the mechanism for feeding the successive books into the clamps.
- Fig. 2 is a rear elevation.
- Fig. 3, like Fig. 2, is a rear elevation showing in detail, however, only certain parts which are indicated near the left end of Fig. 2.
- Fig. 4 is a section taken on the plane 44 of Fig. 2.
- Fig. 5 is a plan of some of the parts shown in Fig. 2 indicating-principally the book conveying belt-and chain and their driving connections.
- Fig. 6 is a perspective showing the highest portion of the infeed conveyer. with the book passing on to the leveling table prior to the closing of the clamp.
- Figs. 7 to 10 illustrate in detail the mechanism for cross grooving the backs of the books.
- Fig. 7 is a rear elevation.
- Fig. 8 is a left elevation, showing also portions of the machines driving mechanism and the gluing mechanism at the front.
- Fig. 9 is a skeleton view in perspective of the cross grooving mechanism.
- Fig. 10 shows a portion of a signature group after the cross grooving operation.
- Figs. 11 to 16 illustrate in detail the mechanisms for applying the cover and breaking and pressing it into place.
- Fig. 11 is a front elevation.
- Fig. 12 is a partial or skeleton view in perspective.
- Fig. 13 is a left elevation partly in section on the plane ,1313 of Fig. 11.
- Fig. 14 is a view similar to Fig.
- resent invention consists intion on the plane 17-17 of Fig. 1, and showing the clamp opening, and the delivery mechanism.
- Fig. 18 is in the nature of a diagram showmg the several successive stages in the manufacture of a pamphlet.
- the successive books B to be bound orcovered are shown as carried in upright pobook clamps 21, each clamp consisting of an inner member 22 and a movable outer or presser member 23.
- the clamp members 22 are hinged together, the hinges forming articulations, so that the carrier is flexible, like a chain, permitting the books to be carried around the ends of the machine when passing from one side to the other.
- Each clamp member 23 is shown fitted slidably to its complementary clamp member to permit relative separation and approach for discharging, receiving and clamping the books; and a powerful spring device 24 is provided for each clamp to hold it closed firmly upon the book unless or until the clamp is opened by some opposing mechanism. Associated with these parts is a roller 24*, which may be moved outwardly to compress the springs and cause the opening of the clamp.
- the hinges or fulcra between the clamps are extended in the form of studs engaging upper and lower clamp tracks or guides 25 which extend in any desired manner, for example, in two parallel stretches along the front and rear sides of the machine.
- the carrier is guided around one end of the machine by curved continuation of the tracks, and at the other end is guided by a pair of large horizontal sprocket wheels or spiders 26 which, as will be explained, serve also for the purpose of driving or advancing the carrier and thereby causing the travel of the books from mechanism to mechanism.
- the source of power from which the carrier and various mechanisms are driven may consist of a belt pulley 29 mounted on the rime shaft 30, journaled in the machine rame.
- a secondary shaft 31 is shown arranged parallel with the prime shaft and driven therefrom at a slower speed by a suitable gear train 32.
- the book carrier 20 may be suitably driven from the shafts 30 or 31 at any desired practical speed, and with an intermittent motion,
- connections from the secondary shaft 31 to the large sprockets 26 may be as follows (see Fig. 8): On the shaft 31 is mounted a small bevel gear 33 engaging the large horizontal bevel gear 34 mounted on vertical shaft 35 which, at its upper end, carries the sprocket wheels 26 which, in their notches, are engaged by the hinges between the clamps of the carrier.
- the delivery located at the point where each clamp opens to discharge the completed book;
- the infeed of the book or loose signature group into the open clamp the infeed commenc'ing with a table at which.
- the books are placed by hand or mechanically in the infeeding mechanism which carries the books beneath the delivery and lifts them into the respective clamps, before arriving at the clamp closing position, third, the trimming mechanism by which the doubled edges of the signature groups are removed; fourth, the roughing mechanism by which the trimmed back edges are slightly abraded to facilitate the entrance of the glue; and fifth, a cross grooving mechanism by which, as explained, the binding or consolidating of the individual sheets by the adhesive is improved.
- sixth the mechanism for applying glue to the back of each advancing book
- seventh mechanism for attaching or applying a pervious strip over the glued back of the book for purposes j the completed book discharged or delivered to a suitable receiving or stacking mecha nism.
- the spring device which is provided with a roller 24 for this purpose,
- the rail portion 37 is carried at the top of an arm 38 which is fulcrumed at its lower end and is held by an adjustable brace 39 in rigid relation with a second arm 40, the end of which carries a roller engaging a cam 41 on shaft 31.
- the adjustment of the brace 39 determines the extent of opening movement of each clamp.
- conducting infeed device 43 is shown extending between the table 42 and the book carrier and comprising a series of pushers 44 moved in time with the rest of the machine.
- commencement of the book infeeding devices and the table 42 are at a lower level than the series of clamps 21 constituting the book carrier 20. This is important for two reasons. Thus, as will be clear in Fig. 2, the books B are brought into the clamps 21 with a lifting.
- clamp 21 is permitted, in which the members relatively separate and approach by parallel motion, guided by transverse horizontal guides or rods, as in my prior Patent No. 1,073,324.
- the clamp guide rods each act as a gage for positioning the book relatively to the clamp before the closing of the latter.
- the lower level of the book infeeding conveyer permits it to be located beneath the discharge or delivery of the machine. This is of additional importance because, as seen in Fig. 1, the delivery may be arranged at the same side as and adjacent to the point of infeed, thus utilizing the entire length of the orbit of book travel from the cover breaking mechanism around the right hand end of the machine to the delivery for permitting the setting and hardening of the adhesive.
- the conveyer frame or bar 45 extending from the table 42 first horizontally and then at an upward incline is grooved at its upper side, as more clearly seen in Figs. 4 and 17, the groove being formed with interior shoulders on which run the pushers 44.
- the extreme right end of the conveyer is formed as at 45, Figs. 2 and 6.
- Each book Bis placed vertically between the fixed but adjustable vertical side guards or guideplates 46, and the bottom of the book rests in the bottom of the groove in the conveyer frame 45,. as seen in Fig. 4.
- the pushers 44 are spaced apart at intervals corresponding with the traveling clamps 21, and-the pushers are connected to and advanced by sprocket chains 47, 47, located on the shoulders Within the grooved interior of the conveyer frame.
- the sheet metal side plates 46 are slightly flared at their upper ends, and at the entrance or beginreferring to Figs 1 to 6, a book nin of the book travel are curved so as to facl itate the operatives setting the books between the plates and in front of the respectlve pushers 44.
- the pushers advanced by the chains 47 carry the books horizontally along the conveyer frame 45 and thence upwardly into the clamps 21.
- the chains 47 are seen to pass around guiding wheels or sprockets 48 and a driving sprocket 49 with which cooperates a sprocket pinion 50 for adjusting the tightness of the chains.
- the book As the book travels along a horizontal part of the infeed it is preferably subject to the action of a pair of rotating polygonal rollers 58 which deliver a quick succession of light blows at the back edges of the signatures so as to jog them into alinement if they have not already been properly arranged.
- the two rolls will be suitably journaled at their ends and will rotate in unison by reason of a sprocket chain 59 which, as seen in Fig. 5, is actuated by a belt 60 extending between suitable pulleys on one of the roller shafts and the shaft 54.
- the conveyer bar 45 As seen in Fig. 3, the conveyer bar 45 is cut away so that the angles of the jogging rollers extend into the path of the books.
- the two side plates 46 form a vertical book groove which is substantially in alinement with the space between the outer and neeaaea inner plates of the open clamp 21.
- the groove between the side plates is narrower than the clamp space so that the book will rise without hindrance from the former to the latter.
- each book reaches the upper part of the infeeding conveyer it commences to enter cornerwise in the open book clamp above it so that as the book receives diminishing guidance from the side plates 46 it receives increasing guidance by the separated clamp members 22, 23.
- a stationary leveling table 61 adjustably secured at the top of a stationary bracket 62.
- Fig. 2 shows one book about to move over the table and another book resting flatly on the table.
- Fig. 6 shows a book that has been pushed partly upon the table. At this stage the book is at an inclined position and it remains so until it has been pushed so far over the leveling table that gravity causes it to straighten out, as shown in Fig. 2.
- the pusher 44 ceases to act upon it, it passing downward around the sprocket wheel.
- the book preferably comes momentarily to rest, standing upright on the leveling table and supported vertically by the open clamp members. This result is effected by timing the sprocket chains which carry the pushers 44 so that each book will be slightly in advance of its clamp.
- a belt such as 51 may be used to accelerate the book for the same purpose.
- the rear clamp guide rod 23 meets the rear edge of "the book, serving to head up or aline the signatures, and serving as a gage to properly determine the longitudinal position of the book in the clamp, while the leveling table 61 serves to gage its vertical position.
- Jogging rollers such as 58 may be provided under the leveling table, to finally insure the complete alinement of the signatures.
- the clamp guiderod 23" now pushes the book forward with the clamp for a short distance until the automatic closing of the clamp, as beforedescribed, causes the book to "e firmly grasped between the clamp members, which occurs before the book has passed beyond the position in which it is supported on the leveling table.
- the width of the groove or space between the guide plates 46, 46 may be adjusted by screw device 63 to suit different thicknesses of books.
- a toggle device 64, 65 may be tripped or broken to the right in Fig. 2 by link 66 and handle 67 for swinging downwardly the inclined portion of the infeeding conveyer frame and this action may be accompanied by stoppage of the machine through a rock shaft 68 connected by arm and rod 69 to a handle 70, see Fig. 8, which is secured on a cross-shaft 71 through which it throws the unclutching device 72.
- a rod 73 to be actuated when a book is jammed at the infeed, for example, by an easily movable false bottom in the conveyer frame, this rod, through a device 74 may unlatch the lower toggle arm so that a spring 75 will break the toggle, thus dropping the infeeding frame and stopping the machine.
- a feeling device 76 is shown located to be struck by a book that has failed to discharge from the clamp, this feeler operating through a lever 77, link 78 and latch device 74 to drop the infeeding conveyer and stop the machine, thus preventing damage.
- I also preferably employ an accessory contrivance controlled by the presence or absence of a book in the clamp after leaving the conveyer. Occasionally a book may not be placed in the conveyer and a clamp may be left empty.
- a suitable feeler to detect this condition may be operated by some part of the clamp when closed, for convenience, by the roller 24*, which takes different positions according to whether the clamp is opened or closed.
- Such feeler may be utilized by mechanical connections of an obvious nature to prevent the cover applying mechanism farther along in the machine from supplying a cover corresponding to the empty clamp. This safety contrivance, however, is not made the subject of claim herein.
- a book infeeding mechanism which like that of the Lewis patent, operates automatically in time with the carrier travel, and serves for entering the books into engagement with the carrier; but difiering from the prior art in that the infeeding movement is not in the same direction as the advancing movement of the carrier, but at a substantial angle to the direction of carrier gluing, and backing; in which latter case the book infeeding conveyer may, of course, 'be united with the delivery of a signature gatherer such as that shown in my Patent No. 1,177,600, in order to obviate hand transfor of the books, or, a gravity or hopper device of a well known kind may be used, the
- the operation of the jogging devices may be further explained as follows:
- the octagon rollers 58 are turned rapidly giving slight vertical blows which aline the signatures vertically.
- the jogging rollers turn in the direction of the arrows so that they are constantly tending to force the signatures to the left against the pushers 44, thus helping to head up the signatures or aline them horizontally.
- the travel of the loose signatures up the incline tends also to head them up against the pushers.
- the dropping of the signatures flatwise on the leveling table again tends to aline them vertically, and this action may be assisted by a holddown spring 79, Fig. 2.
- the clamp pin 23 impacts against the signatures, thus insuring their horizontal alinement before.
- Fig. 1 is shown in plan view an effective trimming mechanism 81 adapted for this purpose, the complete details of which may be ascertained by reference to my aforesaid co-pending application Serial No. 48,959.
- the signature groups which are held upright in the clamps have their folded edges protruding downthe back edges of the book.
- the blade 82 is shown as an endless band knife passing around large pulleys and caused to travel constantly at a high rate of speed. The forward travel of the book is thus utilized to produce the necessary relative feed so that the knife will progressively trim the book from the forward to the rear end.
- Suitable confining means 83, 84 of a rotary nature are shown for maintaining the book and blade in proper relation.
- the mechanism may be driven from the power shafts 30 or 31 or from an independent source. While the trimming mechanism may operate irrespective of the mode of advance of the book, it will be observed, that a steady uniform book speed more effectively cooperates with the blade than would an intermittent or substantially variable speed.
- a roughing mechanism 86 may be employed of the nature generally indicated in Fig. 1, in which one or more toothed wheels 87 are constantly and rapidly turned in such position as to abrade or roughen the book.
- the motion of the roughing wheels being continuous, their action is independent of the mode of advance of the book, whether continuous or intermittent. In other words, like the trimming mechanism the roughing mechanism operates while the book is traveling.
- the grooving mechanism 89 which is seen in general plan in Fig. 1, is best seen in detail in Figs. 7, 8 and 9, and a portion of the resulting book or signature group B is indicated in Fig. 10.
- the grooves G are seen to be shallow, and may be about inch in de th.
- the mechanism comprises a suitable number of cutting tools, which may be termed saws, operated to move at high speed, for example, by using the circular type of saw attached to a fast rotating spindle.
- the entire device is operatcd to lift or move toward the book, and, by arranging for a brief advancing movement of the device, it may be caused to operate while thebook is traveling.
- a plurality of circular saws 90 mount ed, for convenience, on a cylindrical member 91, which rotates with the spindle 92.
- the spindle is shown mounted horizontally and longitudinally in a frame consisting of upright arms 93, 94, 95, all connected at their lower ends to a lower brace rod 96, and being additionally connected by an upper brace rod 97
- the frame 93-97 By lifting and dropping the frame 93-97 the groovingsaws can be brought up into operative contact with the back of the book and restored to inoperative position.
- a pair of rearwardly extending rock arms 98 extend from the lower brace rod 96 to a longitudinal rock shaft 99, which has no movement except of rotation.
- the rock shaft and rock arms are rocked at the proper times by means of a cam arm 100, fast with the rock shaft and having its extremity or stud engaging a rotary cam 101 on the power shaft 31.
- the cam arm 100 has an adjusting device 102 by which the extent of rising movement of the cross grooving device may be predetermined.
- the rock arms 98 lift and drop the spindle carrying frame, and I employ means for controlling the position of the frame as it rises and falls.
- a simple vertical rising and falling movement of the frame is sufficient, and the frame-controlling rod 103, therefore, serves in the disclosed embodiment as a steadying means.
- This rod extends rearwardly to where it is pivoted to the upper end of a swinging cam arm 104, a roller being provided at the pivot, which roller is engaged by a cam 105 on the power shaft 31.
- a spring 106 may be applied to the arm 104 to hold the roller against the cam, which is shaped to control the upperpart of the frame so that the saws will be lifted substantially vertically against the book.
- the spindle frame may be pressed inwardly by strong spring 107 extending from the spindle frame to a fixed frame part of the machine.
- the described devices provide for the movement of the grooving device to and from operative position.
- T will now describe means for maintaining the grooving devlce in motion, that is, for rotating the circular saws at the appropriate speed.
- a belt pulley 108 is splined or otherwise secured on the spindle 92 near its left end, being shown located between the bearing sleeves at the top of the frame arms 93 and 94.
- a belt 109 extends from the pulley 108 to a pulley 110 loose on the frame rod 96.
- Turning with the pulley 110 is a smaller pulley 111, connected by a belt 112 with a driving pulley 113 mounted on the prime shaft 30.
- a shiftable pulley 114 is shown bearing on the belt 112 for taking up the slack, and a spring 115 to maintain yielding pressure is shown.
- the cross grooving circular saws are maintained in a state of rapid rotation, so that, when brought into contact with the book, the desired grooves will be out.
- the grooving device, the frame, etc. may return to inoperative position by gravity, as permitted by the contour of the cam 101.
- the spindle 92 is arranged to slide longitudinally in the bearing collars at the upper ends of the frame arms 93, 94 and 95, the pulley 108 being splined to the spindle, as before stated.
- My plan for advancing the grooving device is to arrange that the book itself, or the clamp which carries the book, shall push the grooving device in the direction of travel while the cuts are being made, the parts being returned each time to normal position, for example, by springs.
- a slotted arm 117 At a convenient point on the spindle 92, the latter is engaged by a slotted arm 117. Relative lateral movement is permitted by the slot, but relative longitudinal movement is prevented by suitable collars on the spindle, as shown.
- the arm 117 ' may be moved longitudinally by a slide 118, which is shown in the form of a sleeve surrounding a guide rod 119.
- the rod 119 is adapted to move up and down in unison with the rising and falling movements of the grooving device, and for this purpose is swung by rock arms 120 from a fixed axle or fulcrum 121.
- a link 122 is shown extending from the lower brace rod 96 of the spindle frame to the guide rod 119.
- the slide or sleeve 118 is, caused to-risc and fall in unison with the grooving device, while the slot in the arm 117 gives relative free play transversely.
- the slide 118 By moving the slide 118 at the proper time and in harmony with the advanclng movement of the book, the circular saws are at the same time caused to advance with the book for the purpose mentioned.
- the slide 118 is shown as provided with an upstanding contact piece 123, adapted to be engaged by a contact 124 on the book clamp device 24. This engagement takes place only when the grooving device has been lifted.
- the contacts are timed so that the actual commencement of grooving occurs simultaneously with or subsequently to the clamp contact 124 coming into engagement with the slide contact 123. It will be understood that the moment the contact 124 strikes the contact 123, the circular saws move bodily forward with the book during the grooving.
- the extent of forward motion may be quite small, as the rapidly rotating saws out very quickly, and the dotted lines in Fig. 7 give an indication of a suitable extent of forward movement. It will be further understood that the forward movement ceases when the grooving device is lowered by the control arm 101. For returning the parts to normal position, a spring 125 attached.
- an abutment 126 is arranged to bear against the inner side of the downwardly protruding book.
- a gluing mechanism of generally well known characteristics This is indicated in the general plan view, Fig. 1, and is shown also in Fig. 8.
- a movable device namely, the rotating roller 129 arranged in the vessel for conveying adhesive to the book B above it.
- Theroller is partly immersed, and its upper portion is arranged to progressively apply to the book the glue lifted by its rotation from the vessel.
- the roller may be automatically driven, as usual, for example, by a sprocket chain 130, so that the upper periphery of the roll advances in unison with the book.
- the chain is shown device.
- the gluing mechanism operates during the travel of the book, and its operation is independent of whether the book be advanced intermittentlv or continuously.
- the vessel may be heated in the usual way to -melt the adhesive.
- gluing mechanism I bodily lift and drop the entire gluing mechanism, vessel, roller and all. is shown mounted at the top of a vertical stem 131, which is slidable in a. suitable sleeve and'is connected by a link 132 to a cam lever 133, Which is fulcrumed near the link and has a long arm extending to cam 134 on the power shaft 31.
- An adjusting device 135 elevation of the gluing mechanism, and gravity lowers the same and maintains the cam and follower in engagement.
- the contour and the timing of the cam 134 are such that the gluing mechanism is lifted as the front corner of each book comes above the glue roller, and is dropped as the rear corner passes over the glue roller.
- the spreading of glue is minimized, and the adhesive may be confined so as not to extend to the extreme corners of the book;
- a safety contrivance may be employed of a suitable nature, which will prevent the rise of the gluing mechanism or the application of glue to the book in case no book cover has been fed corresponding to the book, a cover detecting device of i a usual sort being available for this obvious purpose.
- a pervious strip which may be termed a pervious strip, this consisting, for example, of a suitable length of crash or other woven or fibrous or analogous material, which may be laid over the adhesive so as to assist generally in consolidating the back edges of the signatures, which become firmly attached to each other and to the pervious strip.
- the adhesive permeates the trip and permits the subsequent attachment of a suitable impervious strip, such as a piece of paper, which may be a portion of the cover to be applied to the book. In thisway the pervious strip assists both in the binding and covering operations.
- the drawings show a spool holding device 138, from which the supply of materlal passes over a feed plate 139 to devices whlch cut oil the proper width of strip, and then lift it into proximity with the book and 1
- the vessel 128 determines the extent of a tapas nism may be ascertained by reference to my aforesaid copending application Serial No.
- cover-applying platen or table hereof is lifted to the book and move forwardly, subsequently moving down and back to the original position.
- the cover applying platen hereof which is best shown in Fig. 12, comprises a central longitudinal plate 143 beneath the path of the books, and outlying plates or wings 144 connected by cross pieces 145 to the central plate; o that the platen is a built-up skeleton structure.

BOOK BINDING OR COVERING MACHINE.
Specification of Letters Patent.
Patented Nov. 2%, new.
Application filed September 14, 1916.. Serial No. 150,133.
To all whom it may concern:
Be it known that I, ALFRED BREDENBERG, a citizen of the United States, residing at Champlain, in the county of Clinton and State ofv New York, have invented certain new and useful Improvements in Book Binding or Coverin Machines, of which the following is a speci cation.
This invention is an improved book binding or covering machine. The components or signatures which are to make up the finished pamphlet or other book are supposed to have been gathered or grouped in proper arrangement. The loose signature group may be united or bound together in the machine hereof, and the resulting book may then have a cover applied. If the book has been previously bound, this machine may be in part employed to merely cover the same.
The general plan of this machine is that each of the successive signature groups, which, for convenience, may be termed books, is caused to travel or advance along a designated path through the machine while clamped or held firmly compacted, and during its travel is operated upon by various mechanisms for performing the individual steps in the binding or covering process. Examples of machines of this type are shown in my prior patents Lovell and Bredenberg 476,208 and Bredenberg 1,073,324.
I herein show, as in my said prior patents, the flexible system of binding. The books, held upright, are advanced horizontally and edgewise, and subjected to operations including those of trimming the back edges and applying adhesive and a backing. The signatures ordinarily used in making magazines are multifold, produced by folding the paper for example three times, forming four folds and sixteen pages. The trimming removes the back folds, so that the glue may permeate to every sheet, giving a book that will open out flatly in a manner impossible with wire staple binding. The present machine also resembles my prior patents in that each book, held in spring closed clamps having facewise openable clamp parts, is conveyed at the first side of the machine to a trimming mechanism and a roughening mechanism, and around the end of the machine to the other side, where it travels to a gluing mechanism, a mechanism for aidplying a fibrous backing strip over the glue and mechanisms for applying an impervious outer backing, which may be the pamphlet cover, and pressing and folding or breaking the cover about the sides of the book.
Unlike my prior patents wherein the roughing and gluing operations, but not all of the other operations, proceed while the book is traveling, T herein prefer to follow the well-known plan of having the several mechanisms operable during travel, thus avoiding the delay of thetemporary stoppages otherwise mecessary. The ordinary mode of providing for operation 4 during travel is to cause each mechanism, while acting on the book, to partake of the advancing motion; and I do this in some cases by givlng the mechanism a rotary motion tangent to the book as with the glue rollers of my prior patents, or the Lewis Patent No. 551,776, or the staple applying mecha nism of the Crowell Patent No. 510,841, and in other cases by a reciprocation along the line of travel as with the Lewis cover applying table or the staple applying mechanism of Juengsts Patent No. 846,923, thus avoiding the need of intermittently bringing the books to rest, and permitting the books to be conveyed uninterruptedly from the infeed to the delivery, as is eXemplied in the Lewis patent.
The main objects of the present invention are the general improvement of the efficiency and running qualities of the machine and the particular improvement of the means for feeding the successive books into the clamps, the mechanism for trimming the backs of the signature groups, the mechanism for applying a pervious strip, the mechanism for applying a cover to the book, the mechanism for breaking or bending the cover into place, and the discharge or de livery mechanism.
Another object, in a binding machine, is to combine with, the other mechanisms a K mechanism which operates upon the book to objects the prior to the application of glue for producing a plurality of shallow cross-cuts or grooves at the back of the book to facilitate the entrance of the adhesive and improve the security of the binding.
Other and more detailed objects and advantages of the present invention will be elucidated in the hereinafter following descri tion or will be apparent to those skilled in t 0 art.
To the attainment of the above referred the novel book inding and covering mechanisms, combinations, arrangements, devlces,
details and other features herein described,
illustrated or claimed.
Certain of the individual mechanisms are not herein claimed per se; the particular book trimming mechanism is made the subject of claim in my 00- ending application Serial No. 48,959, filed eptember 4th, 1915, and the particular pervious-strip applying mechanism is made the subject of claim in my co-pending application, Serial No. 108,894, filed July 13th, 1916.
In the accompanying drawings forming a part hereof, Figure 1 is a general plan View of a bookbinding and covering apparatus embodying the present invention, with many well-known parts and many details omitted for simplicity.
Figs. 2 to 6 illustrate in detail the mechanism for feeding the successive books into the clamps. Fig. 2 is a rear elevation. Fig. 3, like Fig. 2, is a rear elevation showing in detail, however, only certain parts which are indicated near the left end of Fig. 2. Fig. 4 is a section taken on the plane 44 of Fig. 2. Fig. 5 is a plan of some of the parts shown in Fig. 2 indicating-principally the book conveying belt-and chain and their driving connections. Fig. 6 is a perspective showing the highest portion of the infeed conveyer. with the book passing on to the leveling table prior to the closing of the clamp.
Figs. 7 to 10 illustrate in detail the mechanism for cross grooving the backs of the books. Fig. 7 is a rear elevation. Fig. 8 is a left elevation, showing also portions of the machines driving mechanism and the gluing mechanism at the front. Fig. 9 is a skeleton view in perspective of the cross grooving mechanism. Fig. 10 shows a portion of a signature group after the cross grooving operation.
Figs. 11 to 16 illustrate in detail the mechanisms for applying the cover and breaking and pressing it into place. Fig. 11 is a front elevation. Fig. 12 is a partial or skeleton view in perspective. Fig. 13 is a left elevation partly in section on the plane ,1313 of Fig. 11. Fig. 14 is a view similar to Fig.
resent invention consists intion on the plane 17-17 of Fig. 1, and showing the clamp opening, and the delivery mechanism.
. Fig. 18 is in the nature of a diagram showmg the several successive stages in the manufacture of a pamphlet.
It will be obvious to those skilled in the art that certain features of the present machine may be employed for the purpose of securing together single sheets of trimmed paper into the shape of pads, which may be considered a form of binding.
I will refer first to the general machine parts and the book carrier and driving connections and the like, and thereafter describe in proper order of operation the several individual mechanisms.
General wmchine parts.
The successive books B to be bound orcovered are shown as carried in upright pobook clamps 21, each clamp consisting of an inner member 22 and a movable outer or presser member 23. The clamp members 22 are hinged together, the hinges forming articulations, so that the carrier is flexible, like a chain, permitting the books to be carried around the ends of the machine when passing from one side to the other.
Each clamp member 23 is shown fitted slidably to its complementary clamp member to permit relative separation and approach for discharging, receiving and clamping the books; and a powerful spring device 24 is provided for each clamp to hold it closed firmly upon the book unless or until the clamp is opened by some opposing mechanism. Associated with these parts is a roller 24*, which may be moved outwardly to compress the springs and cause the opening of the clamp. i
For guiding the carrier the hinges or fulcra between the clamps are extended in the form of studs engaging upper and lower clamp tracks or guides 25 which extend in any desired manner, for example, in two parallel stretches along the front and rear sides of the machine. The carrier is guided around one end of the machine by curved continuation of the tracks, and at the other end is guided by a pair of large horizontal sprocket wheels or spiders 26 which, as will be explained, serve also for the purpose of driving or advancing the carrier and thereby causing the travel of the books from mechanism to mechanism.
naeaaaa The general frame parts of the machine need no specific description other than to mention the base and longitudinal frame parts 27, above which are a series of transverse frame parts- 28. The clamp tracks and various other parts are suitably supported from the frame parts in a manner analogous to my prior Patent No. 1,073,324. Indeed, all of the hereinabove described elements 20 to 28 are shown as substantially the same in principle and structure to my said prior patent.
The source of power from which the carrier and various mechanisms are driven may consist of a belt pulley 29 mounted on the rime shaft 30, journaled in the machine rame. A secondary shaft 31 is shown arranged parallel with the prime shaft and driven therefrom at a slower speed by a suitable gear train 32.
The book carrier 20 may be suitably driven from the shafts 30 or 31 at any desired practical speed, and with an intermittent motion,
as in my prior patent, if that be desirable, for cooperating with any one or more of the mechanisms, or with a continuous motion at a uniform or non-uniform speed, as may be dictated by circumstances.
To give an uninterrupted uniform speed, the connections from the secondary shaft 31 to the large sprockets 26 may be as follows (see Fig. 8): On the shaft 31 is mounted a small bevel gear 33 engaging the large horizontal bevel gear 34 mounted on vertical shaft 35 which, at its upper end, carries the sprocket wheels 26 which, in their notches, are engaged by the hinges between the clamps of the carrier.
At the rear side of the machine in their proper order are arranged, first, the delivery, located at the point where each clamp opens to discharge the completed book; second, the infeed of the book or loose signature group into the open clamp, the infeed commenc'ing with a table at which. the books are placed by hand or mechanically in the infeeding mechanism which carries the books beneath the delivery and lifts them into the respective clamps, before arriving at the clamp closing position, third, the trimming mechanism by which the doubled edges of the signature groups are removed; fourth, the roughing mechanism by which the trimmed back edges are slightly abraded to facilitate the entrance of the glue; and fifth, a cross grooving mechanism by which, as explained, the binding or consolidating of the individual sheets by the adhesive is improved. At the near or front side of the .machine are arranged, sixth, the mechanism for applying glue to the back of each advancing book; seventh, mechanism for attaching or applying a pervious strip over the glued back of the book for purposes j the completed book discharged or delivered to a suitable receiving or stacking mecha nism.
I nfeeding mechanism.
Each clamp must open in order to receive the signature group or book and must thereafter close to clamp the book and convey it successively to the other mechanisms. I
will, therefore, first describe a convenient 1 means for opening and closing the clamps in harmony with the other operations of the machine.
I follow substantially the principles of my said prior Patent No. 1,073,324, by employing a clamp controlling actuator or rail 36 arranged longitudinally and cooperating with the clamp closing spring device 24 in such way as to force the clamp open against the spring and afterward permit the spring to close it. See Figs. 1 and 17. This rail, or at least a portion of it, is moved from the operating shafts of the machine. Thus, in Fig. 1, the extreme right end 37 of the rail is indicated in full and dotted lines as movable outward to press on the spring ,de-
then travels along the entire length of the rail 36 until the new book has been properly positioned in the clamp, when the rail, by its termination or incline at its left end,
permits the closing of the clamp.
As seen in Fig. 17 the rail portion 37 is carried at the top of an arm 38 which is fulcrumed at its lower end and is held by an adjustable brace 39 in rigid relation with a second arm 40, the end of which carries a roller engaging a cam 41 on shaft 31. The adjustment of the brace 39 determines the extent of opening movement of each clamp.
In the machine herein illustrated I follow the plan shown in my said- Patent No. 1,073,324 of employing a table 42 at which the operatives may stand and by hand set the books one at a time into operative relation with the machine. Instead, however, of requiring the operative to place each signature group or book directly into each of the successive clamps, as in my said Patent No. 1,073,324, I prefer to locate the wherein an automatic pusher moved in time with the rest of the machine conducts each successive book from a table into proper position'in the clamping and carrying means.
Thus, conducting infeed device 43 is shown extending between the table 42 and the book carrier and comprising a series of pushers 44 moved in time with the rest of the machine.
It will be noticed that the commencement of the book infeeding devices and the table 42 are at a lower level than the series of clamps 21 constituting the book carrier 20. This is important for two reasons. Thus, as will be clear in Fig. 2, the books B are brought into the clamps 21 with a lifting.
movement, at a substantial incline, which is contrary to the Lewis arrangement of infeeding in the same direction as the horizontal book travel, and is of advantage because the very eifective type of clamp 21 is permitted, in which the members relatively separate and approach by parallel motion, guided by transverse horizontal guides or rods, as in my prior Patent No. 1,073,324. The clamp guide rods each act as a gage for positioning the book relatively to the clamp before the closing of the latter. Another advantage is that the lower level of the book infeeding conveyer permits it to be located beneath the discharge or delivery of the machine. This is of additional importance because, as seen in Fig. 1, the delivery may be arranged at the same side as and adjacent to the point of infeed, thus utilizing the entire length of the orbit of book travel from the cover breaking mechanism around the right hand end of the machine to the delivery for permitting the setting and hardening of the adhesive.
The illustrated details of the infeeding mechanism will now be described. The conveyer frame or bar 45 extending from the table 42 first horizontally and then at an upward incline is grooved at its upper side, as more clearly seen in Figs. 4 and 17, the groove being formed with interior shoulders on which run the pushers 44. The extreme right end of the conveyer is formed as at 45, Figs. 2 and 6. Each book Bis placed vertically between the fixed but adjustable vertical side guards or guideplates 46, and the bottom of the book rests in the bottom of the groove in the conveyer frame 45,. as seen in Fig. 4. The pushers 44 are spaced apart at intervals corresponding with the traveling clamps 21, and-the pushers are connected to and advanced by sprocket chains 47, 47, located on the shoulders Within the grooved interior of the conveyer frame.
It will be noticed that the sheet metal side plates 46 are slightly flared at their upper ends, and at the entrance or beginreferring to Figs 1 to 6, a book nin of the book travel are curved so as to facl itate the operatives setting the books between the plates and in front of the respectlve pushers 44. The pushers advanced by the chains 47 carry the books horizontally along the conveyer frame 45 and thence upwardly into the clamps 21.
The chains 47 are seen to pass around guiding wheels or sprockets 48 and a driving sprocket 49 with which cooperates a sprocket pinion 50 for adjusting the tightness of the chains.
In order to assist the starting of each book up the inclined part of the conveyer frame and minimize the danger of disturbance to the book I sometimes arrange a supporting belt 51 at a portion of the con veyer so that the book at this point is not only pushed forward by the pushers 44, but rests upon an advancing surface.
For transmitting power to drive the chains 47 and belt 51 I show a pair of bevel gears 52 between the secondary power shaft 31 and a pair of gears 53, the last of which is on a transverse shaft 54 carrying at its extremity a pulley 55 on which the belt 51 runs. A sprocket chain 56 and sprocket wheels communicate the rotation to a short transverse shaft 57 which, at its extremity, carries the driving sprocket 49. The parts thus all move in harmony at the same speed and in unison with the book clamp movements.
The successive books, then, are stood upright by hand at the table 42 and set between side plates 46 so that one of the cross pins or pushers 44 will come up behind the book and cause it to slide along the conveyer frame 45.
As the book travels along a horizontal part of the infeed it is preferably subject to the action of a pair of rotating polygonal rollers 58 which deliver a quick succession of light blows at the back edges of the signatures so as to jog them into alinement if they have not already been properly arranged. The two rolls will be suitably journaled at their ends and will rotate in unison by reason of a sprocket chain 59 which, as seen in Fig. 5, is actuated by a belt 60 extending between suitable pulleys on one of the roller shafts and the shaft 54. As seen in Fig. 3, the conveyer bar 45 is cut away so that the angles of the jogging rollers extend into the path of the books.
Each book then continues to travel horizontally until reaching the inclined portion of the infeeding conveyer, when its starts up the incline assisted by the traveling belt 51. It will be understood that the outermost guiding plate 46 is omitted from Fig. 2 to better show the books and mechanism.
The two side plates 46 form a vertical book groove which is substantially in alinement with the space between the outer and neeaaea inner plates of the open clamp 21. The groove between the side plates, however, is narrower than the clamp space so that the book will rise without hindrance from the former to the latter.
The upper portions of the guide plates are cut off horizontally beneath the level of the clamps, as seen in Fig. 6, so as to avoid conflict. It will be understood that in Fig. 6 the conveyer frame and chains are shown horizontally for convenience only, since these are in reality inclined upwardly as seen in Fig. 2.
By the described arrangement, as each book reaches the upper part of the infeeding conveyer it commences to enter cornerwise in the open book clamp above it so that as the book receives diminishing guidance from the side plates 46 it receives increasing guidance by the separated clamp members 22, 23.
As each book arrives at the top of the incline and while still being pushed forwardly under the influence of the cross pin or pusher 44, it comes to a point above a stationary leveling table 61 adjustably secured at the top of a stationary bracket 62., See Figs. 2 and 6. Fig. 2 shows one book about to move over the table and another book resting flatly on the table. Fig. 6 shows a book that has been pushed partly upon the table. At this stage the book is at an inclined position and it remains so until it has been pushed so far over the leveling table that gravity causes it to straighten out, as shown in Fig. 2.
When the rear edge of the book has arrived at the leveling table, the pusher 44 ceases to act upon it, it passing downward around the sprocket wheel. At this stage in the operations the book preferably comes momentarily to rest, standing upright on the leveling table and supported vertically by the open clamp members. This result is effected by timing the sprocket chains which carry the pushers 44 so that each book will be slightly in advance of its clamp. A belt such as 51 may be used to accelerate the book for the same purpose. However, after the book has been leveled on the plate 61 and the pusher has ceased'driving it, the rear clamp guide rod 23 meets the rear edge of "the book, serving to head up or aline the signatures, and serving as a gage to properly determine the longitudinal position of the book in the clamp, while the leveling table 61 serves to gage its vertical position. Jogging rollers such as 58 may be provided under the leveling table, to finally insure the complete alinement of the signatures.
The clamp guiderod 23" now pushes the book forward with the clamp for a short distance until the automatic closing of the clamp, as beforedescribed, causes the book to "e firmly grasped between the clamp members, which occurs before the book has passed beyond the position in which it is supported on the leveling table.
Various adjuncts and accessories in connection with the infeed may be advantageously employed. Thus as shown in Fig. 17, the width of the groove or space between the guide plates 46, 46, may be adjusted by screw device 63 to suit different thicknesses of books.
A toggle device 64, 65 may be tripped or broken to the right in Fig. 2 by link 66 and handle 67 for swinging downwardly the inclined portion of the infeeding conveyer frame and this action may be accompanied by stoppage of the machine through a rock shaft 68 connected by arm and rod 69 to a handle 70, see Fig. 8, which is secured on a cross-shaft 71 through which it throws the unclutching device 72. Further, by arranging a rod 73 to be actuated when a book is jammed at the infeed, for example, by an easily movable false bottom in the conveyer frame, this rod, through a device 74 may unlatch the lower toggle arm so that a spring 75 will break the toggle, thus dropping the infeeding frame and stopping the machine. Further a feeling device 76 is shown located to be struck by a book that has failed to discharge from the clamp, this feeler operating through a lever 77, link 78 and latch device 74 to drop the infeeding conveyer and stop the machine, thus preventing damage.
I also preferably employ an accessory contrivance controlled by the presence or absence of a book in the clamp after leaving the conveyer. Occasionally a book may not be placed in the conveyer and a clamp may be left empty. A suitable feeler to detect this condition may be operated by some part of the clamp when closed, for convenience, by the roller 24*, which takes different positions according to whether the clamp is opened or closed. Such feeler may be utilized by mechanical connections of an obvious nature to prevent the cover applying mechanism farther along in the machine from supplying a cover corresponding to the empty clamp. This safety contrivance, however, is not made the subject of claim herein.
There has thus been described, in combination with the traveling book carrier, for clamping in an upright position and advancing in a horizontal direction each book to be operated upon, a book infeeding mechanism, which like that of the Lewis patent, operates automatically in time with the carrier travel, and serves for entering the books into engagement with the carrier; but difiering from the prior art in that the infeeding movement is not in the same direction as the advancing movement of the carrier, but at a substantial angle to the direction of carrier gluing, and backing; in which latter case the book infeeding conveyer may, of course, 'be united with the delivery of a signature gatherer such as that shown in my Patent No. 1,177,600, in order to obviate hand transfor of the books, or, a gravity or hopper device of a well known kind may be used, the
books being placed in quantities in the device and being automatically dropped or thrust one at a time into the infeeding conveyer. Such an infeeding hopper is shown in Pachter Patent 1,033,265 of July 23,1912.
The operation of the jogging devices may be further explained as follows: The octagon rollers 58 are turned rapidly giving slight vertical blows which aline the signatures vertically. The jogging rollers turn in the direction of the arrows so that they are constantly tending to force the signatures to the left against the pushers 44, thus helping to head up the signatures or aline them horizontally. The travel of the loose signatures up the incline tends also to head them up against the pushers. The dropping of the signatures flatwise on the leveling table again tends to aline them vertically, and this action may be assisted by a holddown spring 79, Fig. 2. Finally the clamp pin 23 impacts against the signatures, thus insuring their horizontal alinement before.
the clamp closes. These various jogging expedients are very important on account of the essential necessity of proper heading up and alinement of the loose signatures or sheets prior to the clamping of the books in the carrier, since any lack of alinement will result in a defective book.
Tfimming mechanism.
The trimming ofl' of the doubled edges or folds of the loose signatures may conven iently be the first step in binding by the flexible method and in Fig. 1 is shown in plan view an effective trimming mechanism 81 adapted for this purpose, the complete details of which may be ascertained by reference to my aforesaid co-pending application Serial No. 48,959. The signature groups which are held upright in the clamps have their folded edges protruding downthe back edges of the book. The blade 82 is shown as an endless band knife passing around large pulleys and caused to travel constantly at a high rate of speed. The forward travel of the book is thus utilized to produce the necessary relative feed so that the knife will progressively trim the book from the forward to the rear end. Suitable confining means 83, 84 of a rotary nature are shown for maintaining the book and blade in proper relation. The mechanism may be driven from the power shafts 30 or 31 or from an independent source. While the trimming mechanism may operate irrespective of the mode of advance of the book, it will be observed, that a steady uniform book speed more effectively cooperates with the blade than would an intermittent or substantially variable speed.
Roughing mokam'sm.
In order to roughen and abrade the trimmed back edge of the signature group to facilitate the gluing, a roughing mechanism 86 may be employed of the nature generally indicated in Fig. 1, in which one or more toothed wheels 87 are constantly and rapidly turned in such position as to abrade or roughen the book. The motion of the roughing wheels being continuous, their action is independent of the mode of advance of the book, whether continuous or intermittent. In other words, like the trimming mechanism the roughing mechanism operates while the book is traveling.
The mechanism is the same as in my prior patent N 0. 1,073,324 in which also the roughing is performed while the book is traveling; and said patent may be referred to for available details of structure, which, for convenience, are omitted herefrom, since the details per se form no part of the present invention.
Gross grooving mechanism.
I believe it to be new in a machine of the present sort to provide in combination with the other mechanisms, such as the book carrier, the trimming mechanism, and the gluing mechanism, a cross grooving mechanism which automatically produces transversely extending grooves at the back edge of the book after the trimming and prior to the gluing, so as to facilitate the glue permeatnaeaeea ing between the individual sheets to afiord a more secure binding.
The grooving mechanism 89, which is seen in general plan in Fig. 1, is best seen in detail in Figs. 7, 8 and 9, and a portion of the resulting book or signature group B is indicated in Fig. 10. The grooves G are seen to be shallow, and may be about inch in de th.
enerally speaking, the mechanism comprises a suitable number of cutting tools, which may be termed saws, operated to move at high speed, for example, by using the circular type of saw attached to a fast rotating spindle. The entire device is operatcd to lift or move toward the book, and, by arranging for a brief advancing movement of the device, it may be caused to operate while thebook is traveling.
Thus, referring to the drawings, there are seen a plurality of circular saws 90 mount ed, for convenience, on a cylindrical member 91, which rotates with the spindle 92.
To permit the bodily lifting and falling of the device the spindle is shown mounted horizontally and longitudinally in a frame consisting of upright arms 93, 94, 95, all connected at their lower ends to a lower brace rod 96, and being additionally connected by an upper brace rod 97 By lifting and dropping the frame 93-97 the groovingsaws can be brought up into operative contact with the back of the book and restored to inoperative position.
To lift and drop the frame a pair of rearwardly extending rock arms 98 extend from the lower brace rod 96 to a longitudinal rock shaft 99, which has no movement except of rotation. The rock shaft and rock arms are rocked at the proper times by means of a cam arm 100, fast with the rock shaft and having its extremity or stud engaging a rotary cam 101 on the power shaft 31. The cam arm 100 has an adjusting device 102 by which the extent of rising movement of the cross grooving device may be predetermined.
The rock arms 98 lift and drop the spindle carrying frame, and I employ means for controlling the position of the frame as it rises and falls. Thus, it may be desirable to swing the frame laterally, so as to cause the saws to move across the face of a wide book. For a narrow book, however, a simple vertical rising and falling movement of the frame is sufficient, and the frame-controlling rod 103, therefore, serves in the disclosed embodiment as a steadying means. This rod extends rearwardly to where it is pivoted to the upper end of a swinging cam arm 104, a roller being provided at the pivot, which roller is engaged by a cam 105 on the power shaft 31.' A spring 106 may be applied to the arm 104 to hold the roller against the cam, which is shaped to control the upperpart of the frame so that the saws will be lifted substantially vertically against the book. The spindle frame may be pressed inwardly by strong spring 107 extending from the spindle frame to a fixed frame part of the machine.
The described devices provide for the movement of the grooving device to and from operative position. T will now describe means for maintaining the grooving devlce in motion, that is, for rotating the circular saws at the appropriate speed.
A belt pulley 108 is splined or otherwise secured on the spindle 92 near its left end, being shown located between the bearing sleeves at the top of the frame arms 93 and 94. A belt 109 extends from the pulley 108 to a pulley 110 loose on the frame rod 96. Turning with the pulley 110 is a smaller pulley 111, connected by a belt 112 with a driving pulley 113 mounted on the prime shaft 30. A shiftable pulley 114 is shown bearing on the belt 112 for taking up the slack, and a spring 115 to maintain yielding pressure is shown. k
By these connections, or any other suitable connections, the cross grooving circular saws are maintained in a state of rapid rotation, so that, when brought into contact with the book, the desired grooves will be out. After each grooving operation the grooving device, the frame, etc., may return to inoperative position by gravity, as permitted by the contour of the cam 101.
In order that the advancing travel of the book may not interfere with the grooving operation, I have provided means permitting the device to operate while the book is traveling. For this purpose the spindle 92 is arranged to slide longitudinally in the bearing collars at the upper ends of the frame arms 93, 94 and 95, the pulley 108 being splined to the spindle, as before stated. My plan for advancing the grooving device is to arrange that the book itself, or the clamp which carries the book, shall push the grooving device in the direction of travel while the cuts are being made, the parts being returned each time to normal position, for example, by springs.
At a convenient point on the spindle 92, the latter is engaged by a slotted arm 117. Relative lateral movement is permitted by the slot, but relative longitudinal movement is prevented by suitable collars on the spindle, as shown. The arm 117 'may be moved longitudinally by a slide 118, which is shown in the form of a sleeve surrounding a guide rod 119. The rod 119 is adapted to move up and down in unison with the rising and falling movements of the grooving device, and for this purpose is swung by rock arms 120 from a fixed axle or fulcrum 121. To raise and lower the guide rod 119, a link 122 is shown extending from the lower brace rod 96 of the spindle frame to the guide rod 119. Thus, the slide or sleeve 118 is, caused to-risc and fall in unison with the grooving device, while the slot in the arm 117 gives relative free play transversely.
By moving the slide 118 at the proper time and in harmony with the advanclng movement of the book, the circular saws are at the same time caused to advance with the book for the purpose mentioned. To this end the slide 118 is shown as provided with an upstanding contact piece 123, adapted to be engaged by a contact 124 on the book clamp device 24. This engagement takes place only when the grooving device has been lifted. The contacts are timed so that the actual commencement of grooving occurs simultaneously with or subsequently to the clamp contact 124 coming into engagement with the slide contact 123. It will be understood that the moment the contact 124 strikes the contact 123, the circular saws move bodily forward with the book during the grooving.
The extent of forward motion may be quite small, as the rapidly rotating saws out very quickly, and the dotted lines in Fig. 7 give an indication of a suitable extent of forward movement. It will be further understood that the forward movement ceases when the grooving device is lowered by the control arm 101. For returning the parts to normal position, a spring 125 attached.
to the contact 123 will suflice.
To resist the pressure created by the operation of the circular saws, an abutment 126 is arranged to bear against the inner side of the downwardly protruding book.
Gluing mechanism. I
Herein is shown at 127 a gluing mechanism of generally well known characteristics. This is indicated in the general plan view, Fig. 1, and is shown also in Fig. 8. Within the usual glue vessel 128 is a movable device, namely, the rotating roller 129 arranged in the vessel for conveying adhesive to the book B above it. Theroller is partly immersed, and its upper portion is arranged to progressively apply to the book the glue lifted by its rotation from the vessel. The roller may be automatically driven, as usual, for example, by a sprocket chain 130, so that the upper periphery of the roll advances in unison with the book. The chain is shown device.
By this well-known arrangement the gluing mechanism operates during the travel of the book, and its operation is independent of whether the book be advanced intermittentlv or continuously.
Since glue is usually employed, the vessel may be heated in the usual way to -melt the adhesive.
I also adopt the well lmown plan of cansprovided with a tightening ing the gluing device to lift and drop, so that it may be moved toward each book near the front end thereof and withdrawn near the rear end of each book. Instead, however, of shifting the glue roller within and relatively to the vessel, I mount the rollerin the vessel in the manner of my prior Patent 1,073,324, Fig. 5, capable only of rotary movement,
and I bodily lift and drop the entire gluing mechanism, vessel, roller and all. is shown mounted at the top of a vertical stem 131, which is slidable in a. suitable sleeve and'is connected by a link 132 to a cam lever 133, Which is fulcrumed near the link and has a long arm extending to cam 134 on the power shaft 31. An adjusting device 135 elevation of the gluing mechanism, and gravity lowers the same and maintains the cam and follower in engagement.
The contour and the timing of the cam 134 are such that the gluing mechanism is lifted as the front corner of each book comes above the glue roller, and is dropped as the rear corner passes over the glue roller. Thus, the spreading of glue is minimized, and the adhesive may be confined so as not to extend to the extreme corners of the book; I
If desired, a safety contrivance may be employed of a suitable nature, which will prevent the rise of the gluing mechanism or the application of glue to the book in case no book cover has been fed corresponding to the book, a cover detecting device of i a usual sort being available for this obvious purpose.
A portion 136 of the Strip attaching mechanism.
I prefer, as in my prior patent, to employ mechanism 137 for attaching to the glued back of the book apiece of pervious material, which may be termed a pervious strip, this consisting, for example, of a suitable length of crash or other woven or fibrous or analogous material, which may be laid over the adhesive so as to assist generally in consolidating the back edges of the signatures, which become firmly attached to each other and to the pervious strip. The adhesive permeates the trip and permits the subsequent attachment of a suitable impervious strip, such as a piece of paper, which may be a portion of the cover to be applied to the book. In thisway the pervious strip assists both in the binding and covering operations. v
The drawings show a spool holding device 138, from which the supply of materlal passes over a feed plate 139 to devices whlch cut oil the proper width of strip, and then lift it into proximity with the book and 1 Thus, the vessel 128 determines the extent of a tapas nism may be ascertained by reference to my aforesaid copending application Serial No.
Cover applying mechanism.
I prefer to apply or place the cover against the glued back of the book, as in my said prior Patent No. 1,073,324 by means of a cover supporting platen or table or platform, which, as each book comes adjacent to it, moves or rises toward the book B so as to bring the cover C in contact therewith. Instead of the mere lifting and dropping movement to the platen, it may additionally have an advancing movement in the direction of book travel, as in the Lewis patent, so that the application of the cover is independent of the nature of the travel of the book, whether steady, variable, or intermittent.
The cover-applying platen or table hereof is lifted to the book and move forwardly, subsequently moving down and back to the original position. Instead of maintaining a quantity of covers on the platen or table, as in said two prior patents, in connection with the devices for gradually raising the level in order that the successive covers may come into proper position, I prefer the wellknown equivalent arrangement of feeding covers from an exterior source one at a time to the platen; for example see Bredenberg Patent No. 1,179,892, April 18, 1916.
The cover applying platen hereof, which is best shown in Fig. 12, comprises a central longitudinal plate 143 beneath the path of the books, and outlying plates or wings 144 connected by cross pieces 145 to the central plate; o that the platen is a built-up skeleton structure. The wings are shown slightly lower than the central member.
The plate 143 is secured at the upper side of a longitudinal slide 146. These parts are broken away in Fig. 12. The slide is adapted to reciprocate longitudinally, as stated,
and for this purpose 1s suitably fitted to a longitudinal guide 147.
It should be noted that the slide and platen extend well beyond the guide 147 at the left, and at the right the guide and platen extend beneath the cover breaking positions of the book. The platen, therefore, constitutes not merely a cover applier at its left end, but a presser at its middle and right end, it being three units long so that each book is operated upon three times by the platen or presser 143.
To produce the rising and falling movement of the platen in order to carry each cover to the book, to rise and fall, as 14, in which, respectively, and platen are in their upper an sitions.
Extending downwardly from the guide 147 at two convenient points are vertical guide rods 148 slidable in fixed bearings 149 and having cam rolls 150 at their lower ends. The cam rolls 150 rest upon cams 151 mounted on transverse shafts 152 driven from the power shaft 31 so as to elevate and drop the platen in harmony with the book travel. The connections may consist of a bevel gear 153 on the shaft 31 engaging a similar gear 154 on a cross shaft 155 which is also provided with a gear 156 engaging a gear 157 on one of the cross shafts 152, an idle gear 158 serving to communicate the motion to the gear 157 on the other cross shaft 152, as seen in Figs. 11 and 13.
The cam 151 is of such contour and timing as to lift the cover applying platen 143 when the book is above the platen so as to properly place the cover on the book.
To give the cover applier an advancing movement analogous to the Lewis Patent to facilitate the accuracy of the cover applying operation, the platen 143 and the slide 146 beneath it may be caused to move longitudinally in the rising and falling guide 147 by any suitable mechanism; for example, a cam 160, mounted, for convenience, on the cross shaft 155, is arranged to act on the follower or roller of an upright cam lever 161 which, at its upper end, as seen in Figs. 11 and 12, is connected by a link 162 with a boss at the under side of the slide 146. In order to hold the lever up to the cam 160, the lever and link may be constantly pulled toward the right by a spring 163.
The contour and timing of the cam 160 are such as to cause the cover applying platen to move bodily in the direction of the book travel at the time the cover is applied to the book, the cam serving to return the parts leftward after the other cam 151 has lowered the platen beneath the level of the book. The total to-and-fro movement may be six inches or so.
It is necessary that the covers shall accurately take their proper position on the members 143, 144 of the platen in order that the covers may register properly with the book. For this purpose shoulders or hooks 165 are provided at the rear end or side of. the platen. These hooks are located on the the guide 147 is arranged best seen in Figs. 13 and the uide, slide lower poplaten wing members 144 so as not to have
