'Y This stapling mechanism and the application of binding wire 18 to the boxblanksis Well knowgn and for'ms no part ofjmy present invention, so far as the specific details-'0f construction ofthe same are concerned. 1

At the feed end of the machine (the right at Fig. 1) the cleat guides14 and 15 are extended for a considerable distance so as to have sufficient length toreceive enough cleats25 to form several blanks. tension is not`essential but is desirable/to permitthe rapid operation of the machine and at various points in the preliminary por# tion of the cleat, guides I provide feed -wheels 26 which are arranged to rotate ina substantially horizontal plane land to en- This eX- gage the inner vertical faces of the `cleats and drive them forwardly throught-he cleat guides toward the staplng plane. In practice, cleats 25 lvary considerably in Width and I have, therefore, found it desirable to mount each feed Wheel 26 upon a shaft 27 carried in a bracket 28 journaled upon ahoriz'ontal shaft29, the shaft 27 being provided with a bevel geai 30 meshing with a Y bevel gear 31 carried by the lower end of Shaft 26 and the bracket 28 being urged in one direction by agspring` 32 (Fig. 8). The feed Wheel 26 is associated with Shaft 27 by. means of friction disks. 33, Vspring 3l; and adjusting hut 35 so'that the shafts 27 may be driven constantly at a speedsomewhat in excess of the normal .forward speed of the cleats so that the feed ivheels 26 will serve plane, as indicated at 41', the track is deected laterally Vaway from the cleat guide and then is turned rearwardly and extended .back tothe initial end of the machine, as

clearly indicated in Fig. 1,

Mounted upon each track 41 are many spacer blocks 42 and 43, the blocks 42 being cleats ofa box b formed for the 1properA spacing of adjacent ank, while the blocks 43. are formed, for the proper spacing betweenthe.

final'cleat 'of one blank andthe initial cleat of 'the succeeding blank. Asa genera-I rule,

Con- Y 'sequently I arrange, near the staphng lane,

and adjacent each cleat gulde, a gui eway 51 pmuel with the'ciatfguide' and in this blocks-which are 'in advance ofthe same.- to and through the"stapl1 ng plane. will.' be readily understood that where agma'chme' ideway. I mount aireciproating ,feeder ar'g52 which' is' ,coxinectedj b'yl 'a/link 53 with-the reciprocatin. arm 45. Mounted w chain guide 63 is provided at lts upper edge uponbarl 52-is a seriesof cleat feeding pawls54 Iwhich are' normally v urged laterally intofthe cleat guides by light springs and these pawls are s'o' spaced `with relation to` each-other that: at` 'least'one of them will engage arear shoulder ofone ofthe cleats 25 before'v it'reaches thestapling plane, the

active pawl or pawls 54 thus servingV to` drive' the cleats and" interspersed spacer is used for' the preduetion ofstandard sizes said pawls being the cleats b'y\aJ guard rail 59. By this ar- Amachine, I "for" associating the slat sheet material-62 s some means which is '1nterof boxes wherein the cleat lengths are mul- .as those shown in Fig. 6 where the blocks 56 are` triangular in cross section and set in grooves 57 formed in the upper face of the .pusher bar 52, said grooves being flanked by notches 5S into any one of which the block may be set. 'To adapt the ma- A chine for handling cleats of any size and placed upon the bar 52 and yet insuring a proper placing of the, final staples' of a blank, I recommend the con-V struction shown in Fig. I O'Wherethe spacer blocks 4.3 are provided with lateral extensions extending into the path of movement of thepawls 54 of the 'pusher bar 52,' the prevented from engaging rangement, the cleats are advanced through erly spaceV adjacent sheetsand to drive the sheetmaterial forwardly to the stapling plane, this being common` practice 'in machinesof this general type. In the present however, I have provided 'means with the cleats so as to produce` crates and in-order to properly associate this sl'at ma- -the machine by force exerted against the f spacer blocks instead of directly against the cleats.

terial with the cleats, I provide adjacent each'cleat guidea general guide 63- through 10QV whichrunsan endless chain 64 provided at- 'l appropriate intervals with upstanding pins 64 between which the slats.62'maybe laid. I

vChain 64.is 'arranged substantially m a verftical plane and is passed around suitable' and, therefore, each bar 52 is' provided vwith pawls68 which are adapted to engage the pins 64 of chains '64 and thus advance the chains, and the 'sheet material, through the machine-'in unison with the cleats. Each with. a portion 71 which overlies landprotects the chain 64`and^serves .as a support .found it convenient to Vincline the chain wardly' toward. the stapling 'plane so that the t'op portion 71 beyond the stapling plane will lie a little below the faces of the cleats.

the amount. of projection vof' the pins 64 -12' for the slats or sheet material 62. I havev .guides '63"'lightly downwardly and for i i 11oidlers 65, 66 and 67., It is essential that thel l chains 64 move inunis'on with, the lcleats tween the slats after the slats have been fastened to the cleats.

The operation is as follows z-In starting- -behind .the initial cleat, the second cleat placed behind this block, the second block 42 run in behind the second cleat, a third cleat placed behind the second block 42, a

third block 42 placed behind the third cleat;

the fourth cleat brought into place, and` a block 43 run in behind it. Slats 62 will then be distributed over the cleats between the fingers 64', of the chains 64 and the machine started in operation, the-bars 52 operating 'upon the cleats and Slat chains to advance the cleats and slats step by step to and through the stapling'plane. In jthe meantime, the feeding operatives at the initial end of the machine are placing cleats in proper sequence in the cleat guides following each cleat with a spacer block drawn into'the cleat guide by hand from thesupply on' track 41 and4 these cleats are driven forwardly and kept up against the cleats which are being advanced by the bars 52, by means of the frictionally driven feed wheels 26 which, because of thelswinging mounting of the brackets 28 and springs 32, engage the cleats properly even though they vary considerably in width. This swinging movementA of the wheels 26, being downwardly, serves to hold the "cleats down in the cleat guides.

Just beyond the anvil 11 the track 4l branches voff from the cleat `guides so that the spacer blocks 42 are'automatically retracted from the cleat guide, as clearly shown at the left of Fig. 3 each succeeding block pushing the blocks which preceded it around the curve 0f the track so that the blocks are nally successively deliveredto the pawl 44 which acts upon them to push them along the outer side of the track 41 toward the initial end of the machine where they will be convenient of access by the operatives who place the cleats in place.

Mechanical means might be provided to push the blocks into the cleat guides after introduction of a cleat but in practice vl have found that the operatives who place -the cleats have ample time to run in the spacerblocks following each cleat without decreasing the capacity of the machine.

It will be understood that other means than the pawl blocks 52 might be provided to drive the cleats through the machine. For instance, as shown in Fig. l1, the cleats may be driven through thecleat guides by endless spur chainslSl arranged to engage the inner vertical faces of the cleats, these spurchains being advanced stepy by step byY any suitable ratchet mechanism driven 1n synchronism with the stapling mechanism.

Where the forward feeding of the cleats is accomplished by engagement of the pawls of the pusher bar either with the rear faces of the cleats or by engagement with the successive spacer blocks, it is, of course, essential that all ofthe pawls of the pusher bar be accurately spaced with relation'to the cleat lengths in order that the four cleats of a series may be kept in proper relative arrangement without any more spacing thai that provided by the spacer block, and it is therefore necessarythat the lengths of the several cleats of lany blank be in multiples of the spacing between the pawls on the pusher bar.

By utilizing the construction shown in Fig. 10, however, where the cleat-advancing forceis applied only to the rear cleat of each set, the lengths of the cleatsneed notV be considered because all of the cleats of each set will remain compactly together. Thedriving force might be applied directly to a rear face of the rear cleat of each set, the long spacer block between blanks being then introduced merely to insure a minimum space between blanks but it is more convenient to apply this driving force to every fourth spacer block so as to carry that spacer blockA forwardly through the machine with the four cleats which immediately precede it.

In this arrangement the spacer blocks will carry the sheet-spacing engaging means and the sheet material may therefore be associated with the cleats accurately and in such manner asvto insure a tight edged box when the blank has been folded into final position.

The stapling mechanism most commonly inuse in machines of this 'character is one in which the staples are automatically formed and immediately drivenas a result of reciprocatory motion derived from a ro tating part of the machine and heretofore it has been necessary to move the box mae terial forward one steppreliminarily to the driving of each staple', the forward -advancement of the box material being equal only to the distance between staples and, as the staples must be driven fairly close together (generally about three inches) in order to produce a substantial box, the number of necessary advancing steps of the' I naterialhas li'nited the speed of delivery of" the machines because, when these advancingI steps areiproduced too rapidly, there is notlosV machine I have overcome thisdiiiiculty by arranging over each cleat guide two staplingmechanisms 12, 12 which are spaced aparta distance which is an odd multiple of the distance which is desired between staples.A The feeding mechanism is then ad- -justed so as to intermittently'advancethe box material through the machine, beneath the stapling mechanism, a distance which is an even multiple of the space desired be tween the staples. As a consequence, the advancingv step of the .material may be; longer, and"therefore lessfrequent for a given output of the`machi11e, While at the same time maintaining the desired. short distance between the staples.
