`In the meantime the cover stockvblanks piled in ther cover stock magazines` generically desigv` nated by lreferencecharacter C;,(Figs. 1, 2, 4 and 5) are beingdelivered one at a time to folding mechanisms D (Figs. 2, 4 and 5) and a match blankfeeder E (Figs. 4 and 5) periodically nserts eachfsuccessive'matchblank into the folded cover' stock and delivers these assembled parts in the condition shown in Fig. "17- tothe conveyor v ...without aguas time describing in uetanthe 00 l e y operations of completing the book, it will be sufficient to state that the comb` blanks are now accurately registered in foldedr covers, the covers are folded over the registered blanks and stapled or stitched, and the striker paint is applied by means which is conventional and hence is not here illustrated. y Y

Thereafter the chain includes several flights to and fro upon which the strikerl paint is allowed to dry, these fiightsfalso rbeing conventional and not here illustrated, and finally the chain returns the finished product to the discharge portion of the machine where the unloader and stacking mechanism generlcallydesignated by reference characterG. (Fig.v l, 2 and 10) nests together theiinished books, compacts them in a stack, and delivers counted units for packaging. The unloading point is immediately adjacent the Vpoint where L the chain is again charged with assembled cover stock and match comb blanks.

I -Having indicated the general organization of the machine, I shall now describe its component sections. y l

The match comb` magazine This being a duplex machine, there aretwo match comb magazines. VInasmuch as they are identical, however, only-one will lbe specifically described. The match vvcomb vmagazine generically designated by reference character A, comprises a suitable support I` extending upwardly from the bed 2 of the'machine frame and provided with suitable bearings for the upper and lower sprocket shafts 3' and 4 respectively. Theseshafts carry sprockets 5 and 6 respectively, over which operate the spaced conveyor chains 1, each such chain being provided at corresponding intervals with outwardly Vprojecting Pegs at 8 constituting supports for pairs of `match combs 8 (Fig. 15)v which are laid thereon by the operator.

In a few minutes the operator may positiona 45 pair of match combs on each pair of corresponding pegs of the conveyor chains 1, and-he is then free to attend 'to other worksince the number of supports for pairs of combs is sumcient to enable the machine to function for a considerable period without further attention.

Ultimately in the progressive downward advance of the pegs 8 supporting pairs of match combs, such pegs pass through notches shown in dotted lines at I0 in Fig..4 inthe supporting plate II on which each successive pair of match combs is deposited as the pegs pass through/the plate. Resting on plate Il in anormally retracted position, are the pushers or ejectors I2 which, in the present device, are three in number. These ejectors are` sychronously actuated by means hereinafter to be described to push the superposed match combs on to the feed table I5 `with their butt portions engaged between thefeed rolls I5. y

The match comb feed and cut-o1? mechanism D The feed rolls I6 constitute a part of the match comb feed and cut-off Amechanism now to be described.

The feed rolls have tapered ends to facilitate the introduction of the match combstherebetween. The upper roll is mounted on av spindle I1 carried by a block I8 fulcrumed on a cross pin I 9 and pressed into operative engagement with the other feed roll by means of the compression spring 20 adjusted as to its compression by set screw 2l. The feed rolls I6 are interconnected by gears 22 andfr23, tov rotate in unison. f

As clearly appears in Fig. 4, there are two sets of the feed rolls I6 associated with that portion vof feed table I5 on to which the match comb pair 9 is pushed by the ejectors I2. There are.two other sets of feed rolls 25 near the right hand end of the. .feed table I5 as viewed'in Fig. 4. These feedrolls correspond in general to feed roll I6 as to their mounting and intergeared connection.

The lower feed roll of each of the sets I6 and 25 carries a sprocket 26 (Fig. 3), the several sprockets being connected for uniform movement by a chain 21. This chain is actuated lbi' the pawl 28 (Fig. 4) which engages the successive links of the chain and is pivoted at 29 to the armA 30 of lever 18, which lever is oscillated by means hereinafter to be described. "The result of this Farrangement is the intermittent advance of the chain and the corresponding Vintermittent rotation of the feed rolls I6 and 25 `adjustable is engaged at its end by the knurled head 31 of the adjusting screw 38. In an ear '39 of block 36 is a set screw'40 which also engages the head 31 of the adjusting screw, whereby such head is confined against 'any axial displacement. Obviously, therefore, the rotation o f the knurled head 31 will adjust the stop arm 34 very gradually in the path of movej ment of the paired match combs 9.

44Coacting with the fixed shear blade 33 is a vertically reciprocable shear blade 42 carried yby slide 43- (Fig. 6)'. This slide may conveniently be reciprocated from shaft 45 by meansof an eccentric 46, eccentric strap 41, connecting rod 48, and wrist pin 49.

as above noted, the rate of feed of the match comb pairs 9 by the feed rolls I6 and 25 is in excess of the actual requirements of the machine. Thus, when the leading ends of the match comb pairs reach'the 'stop arms 34 and the pairs are thereby brought to rest, the continued movement of the rolls results in the frictional slippage of the rolls on the butt .surfaceof the combs; 'This holds the combs tightly to the stop and enables the cut of the shear knives 42 and 33 to be lo- .cated with great accuracy between two consecutive matches on the respective combs. It has been found that any less accurate and less easily adjustable feed is unsatisfactory for the reason that there are changes in the length of the paper, whereof such combs Aare composed, such that other feeds do not definitely locate the cut between consecutive matches.

Sincethe movement of the comb 'engaged by rolls 25 is retarded by the repeated contact of its successively cut end portions with the stop arm 34, the rate of advance of this comb is retarded as compared with the comb freshly ejected from the magazine into engagement with feed rolls I6. Thus, although there is initially a substantial disthe channel |04 in-which'operates the slide-.|05

for `'feeding the previously severed match rblanks |00."` It-will berecalled that the progressively fed match comb pairs have been stopped bythe gauge 34 beneath the shear knife 42 and double match blanks severed therefrom by the 'descent of 'saidshear knife across the shearing surface ofthe fixed blade 33. The double blanks-thus severed are depositedin the'chann'el |04 vin ythe path of slide |05 of the lmechanism E, such slide `being then retracted. As the tuckinfg blade which has rq1ded1thgcoverb1ankss is v'retracted from the blank the feed slide |05 ismoving forwardly ,"to kinsertfthe live ends 'of "the-paired" match 'blanksinto the lfold ofthe cover stockl aswshown inFig. 5. 4 l Y l g.

The continued forward movement oftheslide 'pushes the folded cover f90 as well as the match sequent operations ,performed on the assembled their respective faces. Thevcam follower roller shown in dotted'lines'at ||5tin Fig: 5 operates lin the cam groove ||3 and is mounted upon'a lever ||0 connected by link ||1Ito the arm ||0 of rock shaft 08. This arrangementoscillates the `roclt shaft to tap thev aligning plunger "9| of the coverstock magazinevand to'oscillatethe tucking blade |0| of the cover stock folderand g feeder designated generallybyreference charac- Vand mountedv on a lever |2|1.

Pivoted yconcentrically withlever |2| isthe lever'v |22 connected 'by'link |23 with the fed'slide |05. A resilient connection is established lbetween lever- I2 and lever |22 byl means of the ,threaded post |24 carried by lever |22, and the compression spring l| encircling such post and confined between lever |22 and ear |25 on lever' |2|.

The engagement ofthe ear with the nut |21 on`post |24A ensures the'v positive retraction of slide |05 while,'in the-opposite direction ofA movement, the thrust is transmitted through' the compression'spring |25 so as to 'provide yfor acertain 1 paint isapplied tothe otherwise complete match f degree of lost motion as the pair of match blanks and superposed cover= 99 are thrust homeinto thepocket |08- of the conveyor chain.

4 The conveyor F andits actuating conn actions :11n the preferredembodiment of the invention the conveyor F comprises a chain-having links (Fig. 4) ,f each link carrying onerof the receptaclesl 08 above referred to. From thel right hand hide of Figs. 1 and .2 to the. left handside of suchfigures. lthe'conveyor F follows a circuitous path in the course of which the striker book and is dried thereon before the books. are

f unloaded from they conveyor.` This portion-f thechain, being conventional, is not illustrated.

" Separate means are employed for advancing the chain at different points according to the requirements of the apparatus. Adjacent each end of the main drive shaft 45 (Fig. l) is a helical cam |3| coacting with the successive studs or teeth i receptacles yof the conveyor. A some n importance that thel conveyor movements `be controlled `with accuracy adjacent theload- -ing stations and accordingly,y although the main l conveyordrive'takes place through the sprockets alarma |32 of the crown wheels-|33. The drive to the -chain is illustrated .onlyat'the left hand side vof the apparatuses viewedln Fig. 1 and Fig. 2. Crown'wheel |33'is mounted ona shaft |54 which projectsiat' the rear of the table and carriesa sprocket |35 over which operates the driving -chain i|30 leadingto sprocket .|31 :on shaft |30. Shaft v|38 vcarries the mainhdriving sprocket v|30 .over winch xthe conveyor F passes. as ,shown in A similar sprocket |40'spaced to the leftof sprocket IIS-ls an idler, and the chain passes over sprocket |40 and downwardly around a guide f|4| and thence upwardly over sprocket |39y to provide azblghtA at the unloadingistations here- ,inafter to be described.` Passing to -theright from sprocketl38 as viewed in Figs. 1, Zande, thefeonveyor passes ,beneathI anl idler guide sprocket |43 and thence along the bed of the Y machine. Y At the center 'of the machinethere are two loading stations'of which the disclosure of Fig.,5 is typical.` At -each of these stations the feed vslide |05 is intermittently inserting a match comb -blank intoaV4 cover stock blank and driving the assembled blanks vtogether intoreceptacles |08 .carriedbythe conveyor. Because therearet'wo .such stations theconveyor is made to move two steps in each'. operation, and the two stations are so located as to register with different .alternate It isobviously of `as above described, I'V provide a AIgnore accurate pawl feed l.which takes up slack between the conveyorlinkssand accurately positions the links at the loadingstations. i e.

The maindrive shaft 45 carries a bevel pinion at |45 meshing with a gear A|46 (Fig. l). This gear drives shaft |41 (Fig. 2) from which a chain un; actuates the stitching mechanism |49 which, being conventional, is not shownin detail.

4Shaft |41 also carries a crank |50 which ytransmits. motion throughconnecting rod |5| to. an oscillatory lever |52 pivotedjto the rearwof the 4bedV of themac'hine and provided with apawl 53 riding over the-links of the chain andVupon each oscillation; v,engaging the upstanding lugsv I5.4,Aof fthe severaklinksto advance the chain two steps at eachoscillationr of the lever. y .7,

- vrDuring each dwell in the advance of thechain, pressure is applied tothematch comb blanks to .force themhome into ther cover stock blanks and .tog s eat both blanks in .flnal registry withV the receptacle |00 Ain` which they have been placed. Immediately following this seating or registering voperation, the folding is done. The mechanisms for vperforming AFig.9.v i
