Patented July 5, 1932 UNITED. STATES PATENT OFFICE i LE GRAND L. CLARK, OF BROOKLYN, NEW YORK, ASSIGNOR TO T. W. 8: G. B. SHERIDAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK BOOKMAKING APPARATUS Application filed June 9, 1927. Serial No. 197,616.

This invention is a novel book making apparatus, referring more especially to the making of headbands for books and to the applying of headbands and back linings to 5 books. The general object of the invention is toafford machinery of the kind referred to which will be of greater efficiency and convenience in operation than heretofore known machines for performing similar operations.

A particular object is to afford a superior mechanism for attaching headbands to back lining material or paper in preparation for the attachment of the latter to the book; and in this aspect the novel features can be used either to produce a supply of headbanded back lining material to be used at Wlll,01 to apply headbands to back lining material immediately in advance of the applying of the I latter to the book in the same apparatus. Other and further objects and advantages of the present invention will be pointed out in the hereinafter following description of an illustrative embodiment of the invention or will be apparent to those skilled in the sub- 'ect. 3 To the attainment of such objects and advantages the present invention consists in the novel book making apparatus and the novel features of mechanism, combination, arrangement and detail herein illustrated or described.

In the accompanying drawings, which are to some extent diagrammatic in nature, Fig. 1 may be considered an end elevation of an apparatus embodying the present invention, with certain parts shown in section. i

Fig. 2 is a top plan view of the apparatus shown in Fig. 1. Fig. 3-is a transverse vertical section taken substantially on the line 33 of Fig. 1. Fig. 4 is a similar section taken on the line 4-4 of Fig. 1. Fig. 5 is a perspective View indicating in detail the manner of cutting off and applying to the book a strip of back lining. Fig. 6 in perspective shows a severed strip of back lining material to the ends of which are secured sections of headband.

Referring first to the components of the product or book, B represents the partially completed book, comprising a group of Sigin its complete form, while H is the fabric 7 supply from which the strip is drawn for the formation of the headbands. S is the string drawn from a cop to beembodied in the headband. C is the crash or other pervious super material preferably applied to the rounded book back in advance of the lining paper.

The machine comprises frame parts 10 supporting the various mechanisms to be described. A book holding means is shown consisting of a book clamp 11 as appears in Fig. 1. This may for example be one of the successive clamps of a clamp train arranged to travel around a suitable path or orbit preferably with a'step by step motion, so that the book pauses in the position shown to receive the back lining strip. The crash lining or super (1 may have been applied in an analogous manner at an earlier step or stage in the clamp travel. 7

Upon the base of the machine is shown the standard 12 giving support to the supply roll of the lining paper- L. The paper web, which may be of width equal to the length of the book, is shown traveling upwardly beneath a resistance roller 13 which is opposed by two narrow disks 14 arranged at the extreme edges of the web for the purpose of applying stripes of glue. These disks are shown rotating in contact with a glue roll 15 running in a glue vessel 16, a scraper 17 being employed to remove excess glue from the glue disks 14, or to regulate the amount of glue thereon. In referring to glue any liquid adhesive is intended to be included, such as paste, a mixture ofglue and paste, or the like.

From the gluing mechanism the web of back lining paper passes upwardly and around a guide roll 18 and thence leftward horizontally toward the position of the book and clamp. Beyond the guide roll 18 is shown a lower pressure roll 19 and above the traveling material an upper pressure roll 20. As will be described the headband is applied to the glued edges of the web L as it travels from the guide roll 18 to the pressure rolls 19 and 20. The under roll 19 may be the full width of the mechanism, but the upper rolls 20 are preferably short rolls arranged at the edges of the web, and each of them is shown formed with a groove 21 arranged to receive the thickened edge of the headband produced by the interposed string S. The under and upper pressure rolls may be geared together by gearing 22 as seen in Fig. 4.

Beyond the pressure rolls is shown a supporting table 23 along which the combined lining paper and headband L travels to the severing and applying position. Beyond the table 23 isshown a feeding means comprising a lower feed roll 24 and an upper feed roll 25. These rolls are intended to draw the web with headbands along advancingly in an intermittent manner. For this purpose the upper feed roll shaft is provided witha ratchet 26, shown with six teeth, engageable by a pawl 27 pivoted upon a carrier 28 which swings on the feed roll shaft and is connected by a link 29 with a bell crank lever 30, the lower end of which carries a roller engaging in the groove of a cam 31, this cam also provided with gear teeth engaged by a driving gear 32 preferably turned by power in coordination with the other operations of the machine.

1 It will be seen that each intermittent feed movement throws the headbanded web forwardly beneath the hook B so that it is only necessary to sever a strip of the web, in the form shown in Fig. 6, and bring about a relative movement to apply this to the back of the book, which is assumed to have been provided with a coating of adhesive at a previous stage. The strip severing means may comprise a pair of shearing members, herein illustrated as an upper or fixed knife 33 upon a bracket 34, and a hollow support 35 which constitutes the lower or movable knife, this support rising at a suitable time to cause a shearing action against the upper knife and thus sever the desired strip.

It is advantageous to employ pneumatic means to hold the strip in place until applied to the book. For this purpose the lower knife member or support 35 is shown hollow, with air perforations 36 having their exit at its upper surface. A flexible air connection or hose 37 is shown leading to a suitable pneumatic apparatus. By this means suction may be applied to hold the strip upon the hollow support until applied to the book, when the pressure may be reversed and a puff of air caused to propel or press the strip against the glued back of the book.

The combined pneumatic support and knife 35 is shown as movable upwardly and downwardly in guides 39. A pair of links 40 may extend from the ends of the support 35 downwardly to a pair of arms 41 mounted on a common shaft, one of these arms being extended downwardly as a bell crank and carrying a roll engaging the groove of a cam 42 rotated from the driving gear 32. By this arrangement the rotation of the driving gear causes the feeding forward of the back lining web, followed by the lifting of the support, which severs a strip and applies it to the book, the support then descending prior to the subsequent feeding operation.

The string or core S for the headband may be supplied in the form of a cop or spool 44 mounted on a supply bracket 45. It is to be understood that there will be a supply of string at each end of the bracket, as indicated in Fig. 2. From each supply the string passes beneath a guide roll 46, and these two guide rolls rotate upon a paste roll 47 revolving in a paste box 48. The string, wet with adhesive, passes forwardly along a guide roll 49, which changes its directon to a longitudinal travel with a downward incline as will. be clear from Figs. 1 and 2. In this travel the string passes from the guide roll 49 into position in the fold of the headband fabric H.

The headband fabric is shown accommodated in a supply box 51 at the upper part of the machine frame, and it may be maintained in the form of a roll or a bolt as shown. The fabric strip passes out by exit 52 of the supply box, one strip issuing at each side of the mechanism. .From this point forwardly each strip is gradually folded over as it approaches a tucker 53. The two tuckers are of a general type known in sewing or other machines and serve to bend double the advancing strip, from which point the doubled strip constituting the headband, and containing the string within its fold, passes directly upon the glued edge L of the back lining paper web L. The two tuckers are preferably mounted on a fixed bracket 55, the upper part of which carries a cross plate 56 supporting the tucker at each end. Each of the cooperating tuckers comprises the outer shaper 53 and the inner guide 54, the latter being swingably shiftable in a direction contrary to the feeding direction for the purpose of opening the tucker for threading the strip and string therethrough.

By the described arrangement the string and the headband strip are combined "into a headband in a substantially continuous man ner, this headband being applied to one of the freshly glued. edges of the paper web which is to constitute the back lining, the combined web and opposite headbands traveling forward intermittently as drawn by the feed rolls, and presented beneath the book in order to enable a strip thereof, of the proper width, to be severed and applied to the glued back of the book. It will be understood that plled to the books.

book.

In a case where the headbanded back lining is to be produced'for the purpose of placing in stock to use at will the described severing" devices may be dispensed with and the interpaper has been heretofore handled As regards certain of the features herein disclosed the headband H could be supplied 5 as a preformed headbandto be attached to the back lining web, although preferably the headband is formed as well as applied in the illustrated machine.

Each of the headband tuckers 53 consists of a U-shaped metal piece accommodating the folded fabric and string, with an interior metallic shaping piece 54 pivotally mounted on the bracket 56 in a manner to swing open in a direction contrary to the forward feeding travel, as indicated by the dotted lines in Fig. 2; this permitting the tucker to be opened and the folded fabric and string properly fed and positioned and the shaper swung back into the full line position of Fig. 2.

The relative arrangement of the means for supplying and folding the headband strip H and the means for supplying the string S thereto is important. The string guide roll 49 is laterally adjacent to the advancing strip near the point where its folding or doubling commences. Owing to this arrangement it will be seen that the string entering the fold ofthe strip assists in shaping the latter.

The string draws closely into the fold and is confined betweenzthe tucker and the strip at one side and the inner shape-r or guide 54 at the other side. Moreover the paste or glue supplied liberally with the string helps to secure together adhesively the two sides of the folded headband and to maintain them in their folded condition until subsequently applied to the back lining web. Theheadband material is preferably pervious so that the glue stripe applied to each edge of the web permeates the material-of the headband and causes the two layers or folds thereof to adhere over their entire surface. adhesive applied to the headband is sufficient in quantity and character it may serve to attach the headbandto the web and dispense withthe gluing devices 14, 15, 16. Subse quently the glue received from the book will permeate from the other side, and thus the book, the-headband and: the back lining" will ibe firmly and strongly consolidated. I'n the preferred arrangement the headband strip is iadhesively moistened before" application to the paper web, for example, by the applying -to it, by the freely moistened string, ofmoist adhesive.

Certain well-known details are omitted -herefrom as being understood or disclosed in .prior' patents for. example the upright mittent feed devices replaced byany suitable: continuous feed or take-up means, the combin ed product to be taken up for example in: the form of a roll or bolt in readiness to be i used subsequently in anyback lining machine in the same manner that ordinary back liningand aply a pressure or puflfof air beneath the back lining';.-=these and other features have been fully described in certain'priorpatentsof Br edenberg, for example Numbers 1,248,252

and 1,248,254 issued November 27, "1927; and are not herein claimed per se.

There has thus been described aibook making 1 apparatus. comprising mechanism for making headbands and mechanism for applying the headbands to back lining material and for applying the combined product to books, the same utilizing the principles and attaining the advantages hereinabove recited.
