SPECIFICATION forming part of Letters Patent No. 486,088, dated November 15, y1892. Application tiled August 6, 1891- Serial No. 401,842- (No model.) I

T all whom t may concern:

Be it known that I, LUTHER C. CRowELL,

a citizen of the ITnited States, residing at- Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Newspaper-Trapping Machines,fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The desirability of a simple machine which will automatically fold papers and other publications to the size suitable for mailing and apply a wrapper thereto, and which is adapted to wrap publications of different sizes and thicknesses, `has long been recognized, andl machines of various constructions have been devised for this purpose. The principle upon which all of these machines have operated, however, has been that of folding the papers zo and wrapper together by means of folding blades or jaws or other similar folding devices, the wrapper being of sufficient length to overlap and seal upon the last fold. The machines constructed upon this principle z 5 have not been found satisfactory, especially because they are not well adapted to wrap thick publications nor readily applicable t0 wrapping publications of different sizes or thicknesses.

3o I employ the method of winding or rolling in place of folding, as above described, and in carrying out my invention I use a central core, upon which the paper and wrapper are wou nd or rolled,the wrapperbeing of sufficient length to extend entirely about the core and paper thereon and overlap upon itself for gumming, so as to seal and secure the paper. The core may be stationary during the wrapping operation and the paper wound upon the core by 4o carrying the paper and wrapper about the core but I prefer to wind the paper upon the core by rotating the latter, and in order to cause the paper to wind tightly and within a small compass I preferably employ outside the core an abutment or wiper, by which the paper and wrapper are pressed during the 0peration of winding. I preferably make this wiper stationary and of such a construction as to yield and adapt itself to successive lay- 5o ers upon the core and to publications of diflfound to economize in PATENT Futon,

AND CHARLES W. CARPENTER, OF

ferentthicknesses. Forthispurposethewiper may be of spring metal or mounted in springbearings. The core may be constructed of any suitable form to hold the paper and wrapper during the process of winding, and it is evident that a very simple construction may be used and prove efficient for this purpose` and that the best form of core will depend largely upon the character of the publication to be wrapped. The'core which I consider preferable for general use, however, is adapted to hold the paper at one end during the operation of wrapping,and in one of its preferred forms consists of a cylinder having an opening on one side to receive the paper. This form of core is efficient with no means for seizing the paper other than that of the edges of the opening, as the paper is bent by wrapping about the core, which thus form grippers; but I prefer to use, especiallyfor thin publications, such as newspapers of a few pages, some form of movable grippers to seize the paper as it is received within the cylinder, these grippers being automatically operated, so as to seize the paper at the proper 75 time during or before the winding process and to release it after the wrapper is applied and sealed,so as to permit the removal of the wrapped paper from the core.

The wrapper may be applied in either of two ways, both satisfactory, and one or the other of which may be used, according to the length or character of the paper to be wrapped. With a paper of such length that a convenient product maybe formed by winding the paper about the core, so as to superpose the whole or a part of a second or third layer thereon, I preferably apply the wrapper by placing its leading end inside the rear end of the paper as the latter is about to be closed down upon the previous layer or layers upon the core,so that the end of the wrapper will be closed in between the layers of the paper and held as it is wrapped about the previously-wound paper. This method will be thewrapper material by reducing the length of the wrapper in all cases to a little more than one circumference of the wound paper, although the paper is long and wound to a small size. I may, how- IOO ever, present the leading ends of the paper and wrapper to the core together, so that the two are wound together upon the core. It is evident that when the length of the paper is greater than the circumference of the core this method involves the use of a longer wrapper than the method above described. Vhen, however, the length of the paper is less than one circumference of the core, this method of applying the wrapper is preferably used, the paper thus extending over a portion of the core and the wrapper completing the circuit and securing the paper in the same manner as before, except that the wrapped paper on being removed frem the core will spring out, forming a flat product. This method, employing a large core, may be found desirable in wrapping art-magazines and other publications which require to be wrapped flat full size. After the paper has been wound and wrapped it may be removed from the core either by pushing it endwise off the core or by withdrawing the core, permitting the paper to fall. In carrying outthe former method I provide a movable ejector which acts against the end of the paper, and is preferably carried by arms upon a plunger mounted to slide within the core, the ejector pushing the paper before it during the advance movement of the plunger. To enable the paper to be more easily removed if the paper be wound closely upon the core, I prefer to use a collapsible core. In my preferred construction I mount a portion of the core-wall in such a manner that it may be withdrawn within the core, and I preferably make this collapsible secA tion of spring metal and use it also as the movable gripper above referred to, by which the paper is seized, being held in position to close the gripper during the winding of the paper and automatically withdrawn to open the gripper when the paper is to be removed from the core.

While it is possible to deliver' the wrapped papers directly from the core, I prefer to combine with the core a drying-chamber, to which the wrapped papers pass from the core and in which they remain a sufficient length of time to permit the paste or other adhesive material by which lthe wrappers are secured to set, and I prefer to heat this drying-chamber to hasten this setting. The drying-chamber will be so formed as to hold the wrapped paper in form until the paste has set, or provided with suitable means for this purpose. A simple and convenient construction which I have found effective for this purposeis that of a cylinder or partial cylinder forming a continuation of the core, into which the papers are successively pushed from the core by the ejector, this cylinder being preferably made of sufficient length to hold two papers, so that each paper remains in the dryingchamber during the operation of wrapping the two next papers.

The papers may be delivered in circular form, but in many cases a flat form is preferpurpose of producing this form of product I preferably deliver the papers from the core or drying-cham ber to fiattening mechanism, which may be of any suitable construction. I prefer to use two flat surfaces, between which the papers are delivered, these surfaces moving toward and from each other, so that the papers as they pass to the final delivery are pressed one or more times between the surfaces and flattened.

The simplest form of machine embodying my invention has but a single core, and it is evident that such a machine may be of very simple construction and may be operated at a comparatively-high rate of speed. I increase the capacity of the machine largely, however, by using a plurality of cores, receiving and wrapping papers successively. These cores may be arranged and operated in any suitable manner; but I prefer to mount them in a rotating carrier, so that the cores have two movements, one a movement of rotation, by which the paper and Wrapper are wound, andthe other a movement of revolution about the axis of the carrier, bywhich the cores are successively brought into position to receive a paper and wrapperand to deliver a wrapped paper to the drying-chamber above described, or to a delivery of such other form as may be employed.

Vhile it is evident that the principle of my invention may be used in a machine by which either or both the paper to be wrapped and Wrapper are fed to the machine by hand, and a practical machine may thus be constructed, especially for wrapping magazines and similar publications, l prefer to make the machine perfectly automatic by combining with the construction previously described, by which the papers are automatically taken by the wrapping mechanism and automatically delivered therefrom, feeding mechanisms for both the papers to be wrapped and wrappers. The papers may be taken directly from the last folding devices of a folding-machine or the delivery mechanism of a printing-press; but Where the papers are previously printed and the wrapping-machine is an independent machine they will preferably be placed folded or unfolded in a feeding box or holder and fed mechanically to the core, either with or without folding, as preferred. The wrappers also may be previously cut and placed in a feeding box or holder in the machine from which they are fed to the core by suitable feeding mechanism; but I prefer to use a wrapperweb and sever wrappers of the desired length in the machine, and I provide, also, a pasting mechanism, by which a portion of the wrapper is rendered adhesive for securing the wrapped paper.

It is evident that the machine thus briefly outlined may be varied widely in construction and that the form and arrangement of the different feeding, pasting, wrapping, and delivering devices will depend largely upon able, and for the IOO IIO

the size and character of the publication to be wrapped and the form of product desired. For the purpose of illustration, however, I have shown in the accompanying drawings a complete automatic machine embodying my invention in one of the preferred forms and certain modified forms of construction, and a full description thereof will now be given,reference being had to the drawings, in which- Figure 1 is a side elevation of the complete machine. Fig. 2 is a plan View. Fig. 3 is a front elevation, the shell of the heating-chamber being sectioned. Fig. 4 is a front elevation of the delivery end of the machine.

Fig. 13a is a perspective of the product shown in Fig. 13 on the same scale as the main views. Figs. 21 and 22 are details hereinafter referred to. Fig. 23 shows a machine using a single core. Figs. 24 and 25 are views similar to Figs. 17 and 19, showing a modified form of core. Figs. 26, 27, and 28 show the same form of core applied to wrapping a magazine, the parts being shown in three different positions during the operation of wrapping. Figs. 29 to 32 show a modified form of machine in which the core consists of grippers, the paper and wrapper being seized at their edges by the grippers and removed from the cores by withdrawing the latter from the wrapped paper. Fig. 29 is a sectional plan showing the parts in the position they occupy while receiving a paperv and wrapper.

Fig. 32 is a similar view showing the cores withdrawn for the delivery of the wrapped paper. Fig. 33 is a view similar to Fig. 29, showing a lmodified form of machine in which a stationary core and rotating wiper are used, one end of the wrapping devices being shown in plan and the other in section. Fig. 34 is a cross-section on the line 34 of Fig. 33.

Referring now to Figs. 1 to 22, the complete machine shown therein will first be described. The frame may be vof any suitable form for supporting the operative parts of the machine. As shown, it consists of two main interior side frames A B, in the upper part of which are supported the paper and wrapper feeding mechanisms, and the two exterior side frames C D at the lower part of the machine, in which are supported the wrapping and delivering mechanisms. In the lower front part of the machine a shaft E is mounted in side frames C D, and upon this shaft is mounted to rotate therewith a carrier carrying four wrappingcores a h c dand four drying-chambers cfg h, the cores lying between frames A B. At the right hand ot' the machine, outside frame A, the shaft E is surrounded by a fixed cam-cylinder G, by which the ejector for removing the wrapped papers is operated. The carrier and drying-chambers extend outside the inner main frame B at the left side of the machine and are surrounded by a shell H, forming a large drying-chamber, which is heated by a burner l, placed below-the shell. Outside the drying-chambersis placedthe flattening mechanism K, by which the papers arereceived from the drying-chambers and delivered to the receptacle L, which may be of any suitable form. In the upper part of the machine at the rear side are mounted the paper holding and feeding devices, the latter consisting of a box M for holding the papers fr to be wrapped and feeding mechanism for advancing one paper at a time from the box to the core. In the upper part of the machine at the front side are mounted the wrapper-roll N and devices for cutting and pasting the wrappers 'y and feeding them to the core. The wrapping and delivering mechanisms and the paper and wrapper feeding devices are driven from the main shaft O through the main driving-gear P and suitable gearing, all of which will be described hereinafter in connection with the various parts.

.The wrapping and delivering mechanisms will first be described in detail and then the paper and wrapper feeding devices.

The carrier may be of any suitable construction to support and carry with it in its rotation the Wrapping-cores and drying-cylinders. As shown, it consists of two heads 10 11, which are connected by suitable tierods 12 and secured to the shaft E by a spline, as shown, or in any other suitable manner. The shaftE is driven from the main driving-l gear P through gear 14, pinion 15, and intermediate 16. As the cores d b c d are identical in construction and operation, a descrip- IOC ISOv

tion of one and its operating mechanism Will suffice, and the same references Will be used for corresponding parts of the four cores. The core a in its preferred form, as shown, consists of a hollow cylinder, which is open at one side to receive the paper and Wrapper, and is preferably provided on its inner side, just at the rear of the opening', with a stop 1, against which the paper is received. The opening is preferably made of a length substantially as shown, extending through a considerable arc of the circumference of the core, and a plate 17, preferably of spring metal, is mounted in said opening, so that When in its outer position it lls ont the circumference of the core and when Withdrawn Within the core against stop 18 reduces the circumference of the latter, so as to loosen the Wrapped paper and allow it to be readily removed from the core in cases in which the papel' is Wound closely upon the core. This plate 17 is preferably constructed to act, also, as a movable gripper, the loose end 2 pressing' the paper against the edge 3 of the core next the stop l and holding the paper firmly when the plate is in its outer position. The plate 17 carries upon its inner side a projection or lug 19, by which it is pressed outward to complete the circumference of the core and grip the paper, and the core is provided with slots 4 for arms carrying the ejector, as hereinafter described.

For winding' the paper closely upon the core when the rear end is released it is preferable that an abutment or wiper should be provided outside the core, by which the paper is pressed during the operation of Wrapping. These wipers consist in the construction shown of spring-plates 20, supported by the tie-rods 12, to which they are secured in any suit-able manner. Two of these Wipers 2O are preferably used With each core, being mounted upon opposite sides of the same, so as to approximately surround the core, except at the point Where the paper is received. It is evident, however, that while the form of Wiper shown gives a freespring movement and is adapted for papers of Widely-different thicknesses the Wiper may consist of a single plate surrounding any suitable portion of* the core, or be of any other suitable construction.

In the construction noiv being described, in which the wrapped paper is pushed from the core, I provide a movable ejector, which consists of a thin ring 23, Which moves over the outer surface of the core inside the wipers 20, so as to carry the Wrapped paper with it from the core. This ejector is carried by a rod or plunger 21, mounted inside the core and moving longitudinally therein, this rod 2l having arms 22, moving in slots et in the core, as previously described, and attached to the ejector, as shown in Fig. 2 This plunger 2l carries, also, a cam projection or lug 24:, preferably adjustably secured thereon, as shown, which lug is adapted to engage the lug 19 upon the spring-plate 17 and force the latter outward to complete the circumference of the core and grip the paper when the plunger is in its positiou With the ejector Withdrawn from the core and to pass out of engagement with the lug' 19 and allow the plate to spring inwardly when the ejector is actuated for the purpose of removing the wrapped paper from the core.

The portion of the core a upon which the paper is Wrapped is of a length to accommodate papers of the greatest width to be wrapped by the machine. The core, however, is extended through the drying-chamber e to the head 11 of the carrier, and at its opposite end is provided with a sleeve 25, which passes freely through the gear 13 and head 10 of the carrier. The plunger 2l slides freely in this sleeve, and is freely supported at its opposite end in a vertical support 26, mounted inside the core within the drying-chamber, which support serves, also, as a bearing for the end of the core on the shaft. l The core and ejector rotate together, and this movement ot' rotation is imparted by a pinion 27, mounted` upon the outer end of the sleeve 25 on the core and engaging a pinion 28, carried by a slee'v 29, loose on the shaft E, and extending through the center of the cam-cylinder G to the inside of the frame C, Whereitis provided with a pinion 30, actuated directly from the main driving-gear P.

The driving connections are shown clearly in Figs. l, 3,11, 12, and l5, the pinion 28 upon the sleeve 20 being mounted centrally of the carrier and engaging the four pinions 27, which operate, respectively, the cores a b c CZ, the cores thus rotating on their own axes, driven from pinion 28 and having, also, a movement of revolution with the carrier through the connections of shaft E, previously described. The timing of the gears Will be described hereinafter in connection with the operation of the machine.

For the purpose otl moving the ejector and plunger longitudinally of the core and at the same time permitting their free rotation With the core the plunger 21 carries at its outer end a collar 3l, secured in positionlongitudinally of the rod, but loose thereon, this collar 31 carrying a bowl 32, pivoted thereto, to oscillate freely longitudinally of the rod and moving in a cam-groove 33 in the interior of the cam-cylinder G. This cam, as shown in Figs. 2, 3, 11, and 12, actuates the plunger longitudinally, and is timed to withdraw the ejector from the core for the receipt of the paper and bring the cam-lug 24 into position to close the gripper 17 as the paper is received, holding it in this position during a portion of the rotation of the carrier While the paper is being Wrapped, and then by a quick movement advance the ejector longitudinally of the core to push the Wrapped paper into the drying-chamber, the ejector then being returned to position for another Wrapping operation.

The drying-chamber e is arranged opposite the end of thecore a, and may beof any suit.-`

Any other suitable means, however, maybe used for this purpose. Below the lower ends of the plates 36 37 is placed the receptacle L,to which the papers are elivered.

It is evident that the mechanisms thus far described form a complete machine for wrapping'and delivering lications and that the papers and wrappers may be fed thereto by hand or mechanically by any suitable devices. The operation of wrapping and delivering a paper bythis machine will 'now be described in detail, therefore, the papers and wrapper being assumed to'be fed thereto by hand and otherwise.

In Figs. 1 to 13 the machine is shown after a series of papers have been wrappe and outward, as shown at 85, so that the wrapped with the core ct just after receiving and grippapers may readily be forced from the core j ping a paper.

This mechanism consists of two successivelyassumein the operation of wrapplates 36 37, ping and delivering a paper, as now to be the papers described.

It will preferably be constructed, as shown, of two curved plates of metal arranged opposite each other, so as to form a partial cylinder open on oppositef sides, thus permitting the free entrance of the heated air to the paper for the purpose of drying the paste. These plates 34 are mounted upon the tie-rods 12 by means of screw-threaded studs carried by the plates, so that they may be adjusted for varying slightly the size of the drying-chamber, as shown clearly in Fig. 16. her is preferably made of a length equal to that of two of the papers of the greatest width to be Wrapped by the machine, so that each wrapped paper will remain within the. drying-chamber during the wrapping of the The edges of the plates 34 next the core will preferably be anged arranged in posi from the core and mounted the thickness desired for the product, and bent outward at their upper ends to form a funnelshaped guide, through which the papers are guided from the drying-chambers. v

In the drawings the paper is shown as Wound about the core but once or less,- but itis eviwith a core of this dent lthat this will depend upon the length of the paper and size of the core employed. In the construction shown the core is designed to be about seven inches in circumference, so that the papers wrapped by the first method are previously folded to a length of about nine or ten inches and the product is about three and one-half inches wide. These relative sizes of core and paper will be found to produce a product of convenient form, as shown in Fig. 1S". Itis evident, however, that size papers of any desired length may be wrapped byincreasin g the number of rotations of the core before the wrapper is applied by the first method or increasing the number of rotations of the core before delivery and lengthening the wrapper in the second method, the construction being modified in an obvious mannerl for this purpose. While this size of core will be found-'convenient, it is evident that ifa smaller and moreclosely-wrapped product be desired the size of the core may be reduced to any extentl desired, and that, on the other hand,the size of the core may be increased,so as to form products of larger size, this depending upon the size, thickness, and character of the publications to be wrapped. As above stated,the liattening mechanism may be omitted, if desired, and the papers be delivered in circular forni directly from the cores or d rying-chambers. The form of product in this case is obvious from Figs. 17 and 19. With a light newspaper and core of considerable size this construction would not be desirable; but with a smaller core, so that the paper is wrapped closely, such a form is practical, and with thick magazines and similar publications it will be found the preferred form of product, as will be evident from Figs. 25 to 27, which Show a simple forni of wrapping mechanism for such publications.

While the wrapping and delivering devices thus far described form a complete wrappingmachine, to which the newspapers and Wrappers,or either of them, may be fed by hand, it is desirable for rapid work that the machine should be made automatic by combining therewith paperand wrapper feeding devices. These devices may be of any suitable form and will be varied to some extent in accordance with the size and character of the publications to be wrapped. The machine, with the feeding devices, moreover, may be a couiplete independent maelf ne or forman attachment to a printing-press or folding-machine and the papers be received therefrom.

In the drawings I have shown my invention embodied in a complete independent machine of a preferred form, in which the papers are previously folded to a convenient size and then fed from a .box or holder to the wrapping devices either with or without another fold. It is evident that the wrappers may be previously formed and fed to the machine from a holder in a similar manner; but I prefer to feed the wrappers from a wrapper-Web and combine with the feedingdcvices eutting and pasting devices, by which wrappers of the desired length are severed and pasted, the machine thus being made automatic and capable of Very rapid operation.

The paper-feeding devices will now be described in detail.

The holder M, in which the papers x to be wrapped are placed, is mounted in any suitable manner at the top of the side frames A B. and is preferably constructed with its sides 47, carried by bars 48, sliding in the frame of the machine, and held in position by setscrews 49, so that they may be adJusted to accommodate papers of different widths and the papers still be held centrally of the box and in proper position relatively to the feeding devices and cores. The rear end of the box 50 is also made adjustable by means of set-screws 51 to accommodate papers of different lengths and hold the papers forward in the box in proper position. The bottom of the box is formed of slats 52, placed at suitable distances apart to allow the passage between theni of feeding-iingers 53, carried by a feeding-cylinder 54 below the box for the purpose of feeding` forward the bottom paper, thefingers 53 being preferably made of rubber or roughened for this purpose. n The feeding-fingers preferably extend within the box a sufficient distance to raise the body of papers during the feeding movement, and one oi more curved spring-fingers 55 are mounted upon the front end of the box, so as to bear upon the paper as it is advanced by the feeding-lingers, the lifting of the papers tending to vloosen and separate them, so as to allow the bottom paper to be fed forward, and the curved spring-lingers, in combination with this lifting feature, operating to prevent more than a single paper being fed out. l'o aid in securing this result, a series of pins 5 are provided, which are carried by a plate 56, mounted on the frontend of the box over the springfingers, and point downward between thehugers. The spring-iingers 55 are so arranged relatively to the papers and pins 5 that the passage of a single sheet does not press the spring-fingers upward sulliciently to uncover the pins 5; but upon the passage of two or more papers below the spring-lingers they are'raised sufficiently to uncover the pins 5 between them, which thus engage the front edge of all the papers except the lower one and hold them against movement from the box, the lower paper being allowed to pass forward. To secure the accurate positioning of the pins 5 relatively to the papers and spring-lingers, the plate 56, carrying the pins, is preferably slotted, as shown, and secured to the box by means of the set-screws 6, so that it may be adjusted vertically toward and from the spring-lingers. rIhe spring-fingers and pins are shown as extending in series across the full width of the paper; 'but this is not necessary. A single finger and pin 4may be sufficient in some cases,
