To all whom it may concern v Be it known that I, DANIEL Rmsnn, a

citizen of the United States, residing at Cleveland, in the county of Guyahoga and- State of @hio, have invented a certain new and useful Improvement in Machines for Stitching Pamphlets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a machine for binders use whichis adapted for the assembling, stitching, folding and backing of pamphlets, catalogues, signatures and the like, the particular aspect of the invention to which this application is directedbeing the mechanism whereby the pamphlets, catalogues signatures, etc. may be removed from the assembling and stitchin means. O t) 1 closing, and stacking of pamphlets, or the like may be effected with a maximum of rapidity and a minimumof attention, while the more particular objects of the invention. forming the subject of this divisional application are the provision of a machine for the rapid, accurate, and eilicient closing oi books or pamphlets, the expulsion of all air contained therein so that thesame may be stacked in a minimum of space; the provision of simple mechanical means whereby these operations may be effected in a rapid and reliable manner; while further objects and advantages will become apparent as the description proceeds. f lnthe drawings accompanying and to l part of this application, :1 have d.

closed one operative means in which my in veutive idea may be embodied. the same being the particular means heretofore disclosed and claimed in my prior application stitching machine, WVllQlEGll the pamphlets are carried, and the iueanstor ejecting said 'amphlets,foldingf and closing the same; Fig.2 is a top plan December 1908, Serial No. 466,756

1 represents a substantially horizontal feed saddle, supported on suitable standards 22.- This saddle is substantially the, shape of an inverted \i, as will appear from Figs.

3 and 1 and forms a sua ort for the books or pamphlets while the same are being carried to the stitcher (not shown), and from the stitcher to the folding and ejecting mechanism, the apex of the saddle receiving the middle portion of the open book.

Carried by a bracket .3 atone end of the saddle is a counter-shaft 4: upon which is mounted a pair of grooved pulleys 55,

each of which receives one of the continuous carrier belts or tapes 66, the sides of the saddle being preferably broken away to permit thesetapes to run freelyfrom end to end of the machine. The other end of the saddle is preferablyprovided with si nijlargrooved pulleys (not shown) I receiving the opposite ends of the belts ortapes, and the upper. portion of each of said belts or tapes pro ectsupwardly above the surface of the saddle'so that the pamphlets may come into frictional contact therewith. The U the right-hand end of the machine, will be carried toward the left and into the foldin and removing mechanism here illustratec.

by the shaft 7. One such stop 8 and cam 9 are illustrated in Figs. 1 and 2 hereof,

although it will be understood that in prac-- tice several such stops are employed whereby the pamphlets are retarded in proper relation to the stitching mechanism to permit thestaples or stitches to be attached thereto in proper position. It will also be understood that these stops perform a further function of regulating the exact timewhen the pamphlets shall arrive at the folding and ejecting mechanism, which is the reason that one such stopis illustrated herein.

-,The main power shaft 12 ofrthe machine extends parallel with the shaft 7 and is provided with a suitable pulley 13 whereby it may be driven. "Secured to the end of the shafe 7 is a sprocket wheel 1e driven by a chain 15 from a sprocket lhcarried; by a gear wheel 17 which meshes with a pinion 18 carried by the shaft 12. The sprocket.

16 and gear 17' are journaled upon a stud carried by an arm 19, the inner end of which is journaled about the shaft 7, as shown in Fig. 3, so as to permit the use of gears 17 of different size, thereby varying the ratio of the speed of the shaft 'r'to that of the shaft 12. The arm 19 is maintained in adjusted position by means of a segment 20.

in a well known manner. The counter-shaft 4 is also geared to a yack'shaft 21 parallel to the shaft 12, the jack shaft 21 being provided with a sprocket wheel receiving a chain 22 which in turn passes around asprocket wheel carried by an idler shaft 23 carrying a second sprocket 24 which is connected by means of a chain 25 with a sprocket 26 carried by the main shaft 12. of the fact that the counter shaft 1- and its pulleys 5-5 are located underneaththe inverted ll-shaped saddle so that direct driving is inconvenient. It will be understood, however, that many other expedients than thatillustrated herein may be employed to effect such driving.

With this construction it will be understood that the main shaft 12 is continuously The idler shaft 23 is employed because driven and that the pulleys 55 together with their belts or tapes 66 are also driven at a continuous uniform speed, such speed being fixed with. regard to that of the shaft 12. The shaft 7 is also constantly driven but at a speed whose relation to that of the shaft 12 can be changed by suitably choosing thesize of the gear wheel 17. Accordingly it will be obvious that the tendency of the belts or tapes'6(3 is always to draw pamphlets or signatures frictionally from the right-hand toward the left hand end of the machine and will do so unless the motion of thosepamphlets be arrested by means of the stops .8. Means is also preferably provided whereby the stitcher (not shown) is governed by the shaft *5 to the end that the stitcher and the stops inay'operate in proper relation. Whether or not this arrangement be employed, it is obvious that the last of the stops, 8, will control the arrival of the pamphlets at the folding and discharging mechanism. The mechanism for folding these pamphlets and moving them from the saddle will now be described.

Journaled in the frame work of the ma chine adjacent to the left hand end thereof are a pair of parallel rollers 80 and 31, said rollersbeing spaced from the apex of the saddle and parallel therewith. One ofthese rollers, as 30, ispreferably mounted in slidablebearings, as shown at 32, and is yieldingly pressed toward the opposite roller, as by means of a spring 33. The other roller is positively driven from the shaft 12 by means of a chain 3st or the like. Journaled in the frame parallel with the rollers 30 and 31 are other rollers and 36, and around all of these rollers are stretched a plurality of endless bands or belts 37, each of these belts passing around rollers 30, 35, and 36, and over the roller 31, as shown in Fig. 4'.-

Referring to Fig. 2 it will be seen that each of the rollers and 36 is illustrated as a separate pulley, mounted upon. a shaft of smaller diameter, although this is a matter of design and it is not essential. It will also be seen from Figs. 8 and l that the portion of each belt 37 between the rollers 31 and 36 is substantially parallel with the ad jacent side of the saddle 1, the roller 35 being so arranged as to cause the entire belt to run without interference.

The apex of the saddle 1 is formed at the point between the roller-s30 and 31 with a longitudinal slot 1O (see Figs. d and 5), and mounted beneath this slot is a long, narrow knife 41 carried by the upwardly extending arms 1-2, said arms being integral with the lower ends of the swinging levers 13 pivoted to the frame work at 14. Secured to the shaft '7 isva cam finger -l6 and connecting this cam finger with one of the arms 13 is a link 47. This link is preferably slotted at its forward end as shown at {L8 in Fig. 7, seas to slide upon the shaftf,

being thereby supported for reciprocation relatively to that shaft.

of thelink is provided with a pivoted roller The forward end as to draw the booklet upwardly and around the roller 31 and into a downwardly sloping channel defined. by the guldes' orplates hereinafter described, and their action is of the greatest importance since they serve to press all air from between theleaves and permit the books to be packed in minimum of space. The knife a1 is retracted by means the spring 49 i Carried by. the standards 22 below the saddle is a horizontal platform consisting of a pair of flat members 5050 spaced apart as shown in Figs. 2 and 6. Each of these members is formed with a pair of transverse slots 5151 and mounted in an upright position upon each of these members is a side board or guide 52 secured in place by means of thumb screws engaged in said slots. Secured to the inner faces of the Sideboards 52 are vertical guide membersbi, having their upper ends bent substantially parallel with the belts 37, as shown at 54 (see Figs. 3 and 4), this portion being interposed between said belts and the saddle l and adapted to receive the booklets as they are discharged fromthe rollers 30 and 31'; Carried by the inner faces of the side boards a short distance forward of the guide members 53 are other shallower guides 56, the upper ends whereof are extendedto apoint adjacent the roller 86as shown in Fig. 4. Mounted between the members 5050 is a reciproc'able rodtZ, the rear end whereof is articulated to a lever 58, pivoted at 59 and yieldingly held "in rearward position by means of a spring 60. A link 61 connects this lever with the end of a second lever 62 pivoted at 63 and having its upper end adj acent to the shaft 7. Arcana finger 64 carried by this shaft serves to oscillate said lever once at every revolution. Secured to the rod 57 is an upright plate 65, the'width whereof is less than the distance bctweeirthe guide members 58.

In setting up the machine, the distance between the side boards 52 is made slightly greater than the length of the pamphlet to be sewed, the distance between the guides 56 being slightly less than the length of such pamphlets. The adjustment ofthe cam fingers 46 and 6 L is such that the'plate 65 will be held in retracted position, as illustratedin Figs. d-jand 6, at the instant each book is "ejected from the saddle and allowed to fall" to the receiving platform. linmedi;

ately thereafterthe plate 65 is allowed to thrust forwardly by the spring 60, whereupon said pamphlet is fiiclred past the guides 56 and pressed againstthe rear of the p1 already deliver-ed; The guides 56 will pre- I vent saidf pamphlet from falling bacl: into the pathof the succeeding pamphlets: Pawls are also carriedby the platform members 50 and still further preventthe return of the books ejected. v

,nwin be apparent from the foregoing that the, whole operation of the machine is regulated and controlled by the shaft 7,

I and jthahowingto the arrangement of the stop 8; and cam 9,one pamphlet will be ad.-

vanc'ed alongthe saddle for eachrotationof the shaft. 3 Thephase relationfbetween the cam 9 and cam 426 is'so adjusted relatively to the speed of the belts or tapes 66 as l to permit each pamphlet to advance just a suff cient distanceafter its release by the stop to be brought into the proper operative relation to the knife stl. The elevation of. the knife then causes the pamphlet to be caught between the rollers, whereupon the 1:

-rrolled shut; The belt-s37 cause the pamphlet to be deflected aroundthe roller and directed into thechute defined be tween. thebelts Bland guides ti l-whence falls upon the platform 50 as above described. j i

l Vhihl have described theme of endless belts or 'bands g'? in connection with the rollers 30 and 31, it will be understood" that these belts or bands are of very small thickness and servemerely to direct the movement of the books or pamphlets after their removal from thesaddle, but withoutany moving and closing the pamphlets could be employed with saddles of other than -V' nife is retracted, the pamphlet beingthere v shape, that "the lrnife whereby the pamphlet-sare thrust between. the closing rollers could be operated. by other mechan sm than that herein disclosed, that great changes could be made'in the stacking mechanism,

o that the same could be entirely dispensed with without interfering with the present invention, and generally that great changes in constructiom arrangement, and operation of the parts could befmade without departing from the scope ofImy invcntive idea. Therefore, whileI have neces sarily described my invention in detail and pointed out those features of construction which commend themselves to me as being most desirable, I do not propose to limit mylf to the details of construction or arrange nt herein described except as the same inay be positively recited in the claims here to annexed or may be rendered necessary by theprior state of the art.
