wheel 94 having upon its circumference a brake band 96 whose opposite ends are conneet/ed at 98 and 100 to a short lever 102 suitably pivoted on the frame and rockable by a lever 104 which is in turn connected b the rod 105 to the rocker arm 90. It will be seen that when the rocker arm 90 is pushed to the left by the heart shaped cam the movement of the short lever 102 tends to bind the 4brake band 9G aboutA the brake Wheel :md -lock it, and that movement in the opposite direction of the parts named tends to release this brake ban-d. In practice, the parts are so proportioned and adjusted that this brake band seriously grips the brake wheel 94 only when the extreme tip portion106 of heart shaped cum 66 enages the roller 92 and at other times the grohe Whecl94 runs freely inside the brake band. The proportion of the lever 102 to the other parts is such that this grip-ping action, when the tip 106 of cam 66 passes roller 92, takes place very sharply and strongly, thereby positively stopping the shaft 20 `at this time. This mechanism is designed to bring the endless sprocket chains and the parts which they pro-petto a sudden and positive stop at desired intervals, as

fully appear. Also rigidly connected to the shaft 20 by any suitable means is a ratchet wheel 11() Whose teeth are adapted to be selectively engaged by at least one of a plurality 0f dogs 112- suitably vpivotally mounted upon a head 114 of a rocker arm 116 journaled loosely upon shaft 20 and reciprocated Iby a rod 118 connected to rocker arm 90. The result of this construction is that whenever rocker `arm 90 is moved to the left by lthe heart Shaped cam 66 some one of the dogs 112 is engaged with the surface of the Wheel 110 and therefore the 'wheel and consequently the shaft 20 is rotated to the left. When, however, heart shaped cam 66 has passed its tip 106 over wheel 92 permitting spring 120 to move arm 90 to the right the teeth 112 click idly over the ratchet teeth of Wheel 110. From the foregoing it will be apparcnt that movement of rocker arm 90 to the lett positively drives the shaft 20 and attached parts in a counter clockwise directiona given predetermined distance and that on the instant this movement of the rocker arm 90 and consequently of the shaft 20 ceases the brake devi-ce grips the brake wheel 94 and prevents any over-movement or overlash of any of the parte.

Rigidly mounted upon cross member 18 as best seen in Figs. 1 and 6. and with its center in the same vertical plane as the arm 90 and the rod 118, heretofore described, is a longitudinal rack 126 rigidly secured in position' `by bolts or screws 128.

In practice, it is desirable to here these chains of such e length that they will, in the course of one complete passage through the machine, take care of et leest two complete box blanks of four Sides each. The chains are divided up `by push members which will be hereafter described carrying the pins 160, heretofore referred to, into a given number of box blank sections spaced :as nenrly'ns practical the sitme distamee apart between successive Ybox sections. In Fig, 1 the push members and the cleats for one euch complete box blank ere shown, there being lfive Apush members for each box blank comprising n. front push member 161, a rear push member 168 and three inten mediate push members 170.

All of the push members are dike in that they have ar similarly shaped body portion 1?'2 provided with a. gripping jaw 174 oontif-oiled by screw 176 so that they moy be ndjustnbly clamped on the T shaped lug 38 heretofore referred toon the side of the chain, and the screws 176 nre selectively insertible in different holes in the upper surfarce ef the push member thereby allowing for adjustment of the push members even up to a. point when they partially .project over the ends of the longer links of the chain. Each one of these push members on the chain which runs adj acentito the operating mechanism of the machine, (the front one as viewed in Fig. 1,) carries one of the pins 160. The push members upon the opposite chain do not need this pin except that the front push inem-ber is there provided with a corresponding pin 180 whose functions will be hereafter described.

All of the push members on both chains have projecting from them push pins 182 which project into the path of travel of and engage the box cleats 52, heretofore described, with the result that each one of these push pins engages the adjacent box cleat traveling through the machine and forces it along,` the track provided for it on an angle iron J heretofore described. In order to readily insert these cleats on this track, these push members and consequently the push pins 182 are spaced farther apart lengthwiseA of the chain than the lengths of the cleats and their ultimate positions with reference to each other require. Each cleat* is pushed up against one of these pins by the spring tension mechanism 234 hereafter described.

Rigidly extendingr vertically from each front push member is a finger or lug n184: and corres ndingly placed upon each rear push mem er is Ya similar rigid linger 186. Pivotaliy mounted Vupon the side of each of the intermediate push members is a vertical linger 188 whose rotation in a vertical plane is Vlimited by the pins 190 (see Figs. 2 and 4). This construction allows a limited movement of these vertical fingers so as to permit slight variations in the widths of the box sides which, in the manner well known in the art, are placed acroV the sprocket chains over corresponding cleatsV and between these fingers on successive push members. As the placing of these box sides is well known in the art, only one box side 192, is shown in dotted lines in Fig. 2 so placed.

Referring to Figs. 5, 7 and 8, the bar 16 of the frame has rigidly' attached to it by screws 194 two bracket members 196, one above each of the sprocket chains of the machine, in which is pivoted by means of the cylindrical members 198 the longitudinal bar 200 whereby this bar 200 is rotatable on its own axis. Hooked over this bar 200 are two wire cuto machines 202, well known in the art, one foreach sprocket chain. These cut-off machines are provided with shear members 204 operated by the combined cction of the spring 206 and the depressible rod 208, in the ordinary manner. .Reciprocably mounted in suitable slots 209 cut in the operating head is the horizontal bar 210 driven by connecting rods 212 operated by secantric: 914 on the 1min drive shaft 54, the

V216 on this bar 210 are thus broug brackets t in contact with the upper ends of rods 208 the cutoif shears 204 are operated.

Asthis har 210 reciprocates at each revo-V lution of the main shaft and as the action of the cut-oil' shears is only required intermittently, the time ofoperaton of the cutoil' shears is regulated by Swingin the cutoff mechanism so that the ends o? the bars 208 are Vonly in the path of travel of these. brackets 216 when it is desired tohave cutting el'ected by the shears 20L This tiltin of the shearing mechanism is made possib e by the fact of their being mounted upon the rotatable bar 200'2 and the rockin motion is effected automatically by the fo lowing mechanism: Ri idly connected to and extending from the. r 200 at any suit able point'is a `short Varm 218 having ad justably connected to it a connecting rod 220 whose opposite end is ivoted at 222 to the shorter arm 224 of a be l crank mounted on shaft 226 whose longer arm 228. is engaged by the pin`180 carried by the front push member on the rear chain, as heretofore described. Pin 180 operates both arm 228 to control the-cutting-mechanism and. also the shaft to control the throw out clutch.

Fig. 8 shows the shears in operative position, while Fig. 24 shows the same in 1noperative position.

Wire, is supplied to the machine by mechanisn well known in the art, and therefore not here shown, so as to pass under the standard, well-known, prior art stapling mechanism 230 also Voperated by the reciprocating bar 210 and thence under the cutoii shears 204. Were the wire not severed successive complete box sections delivered by the machine would be connected by the wires with resulting tangling and other confusion in handling the product 'of the machine which, in rior machines, has been taken care of by c ipping the Wires by hand as each complete box blank comes out of the machine. In this machine when one complete box blank has been delivered from the machine and another box blank is about to be formed and preferably after one` or two staples have been driven im the front cleats of the next box blank, shown at the left of Fig. 1, and across the wire thereon so result being that when projectin as to prevent the ends of the wire getting` loose and therefore'out of control lo@ thc" machine, the pin 1S() on the front pushincmber of the now entering box blank enga s arm 228 and thusswings the cut-oil' mec anism to position under the brackets 216 whereupon on the next descent of thse brackets, they strike the upper ends of the rods 208 and thus force the' cutting jaws l 204 to sever the wires, one on each side. cut of mechanism is returned to normal position by the spring 400;' f

If "nephnlgility of workmen are employed about the machine so that continuons operation is possible the cani (S0 may beeither wholly omitted or nrrenged by well known means to be thrown out of eiieetive operation.

Operation.

Assume th nt the machine is in the position shown in the drawings with the cleats for n complete box in such position; that the box sides? not shown in the dmwings, nre placed over them; that the wire, not shown in the` drawings, is in position ready to be attached; that 'the automatic stnpling mechanism is supplied with e suitable supply of material ready for use and that power is applied tothe shaft 54 ready for use. Also assume that before the starting of the machine on this cycle of operation one or more staples have been driven in the left hrend ends of the first o r left hond cleats. The operator now takes hold of hnndle 5S niej-ees itY to the left thurs throwing in eliiteli 56 and vsterling; the me chine. .As soon es shaft 54 begins to rotate in e counter eioekwise direction it drives arm 90 to the left this through the engagement fof. the p11-wis 112 with the ratchet teeth on een oel-ry thegiJ-"before the top 106 of cam isf'eitehd; et which point brake meche- 'nieni `gel-w96Y takes oontrol of the/shitft 2L lend sharply stops it and consequently the As the high point 106 in com 66 passes rol r 92 the spring 12() begins to draw lever arm 90 and erosshend 130 to the'right n s viewed in Fig. 2, the sprocket chains and work thereon reu manning stationary. This movement oit' these ports continues until, in the first instance. dog 152 engages notch 244 in plete V242 whereupon the :crossheed is stopped. During this Short movement .of the crossheml sind the continued movement of the mein shaft Vbefore erin-9() begins to again move to the left estepiehefheen driven by the stnpllng meehenism() Ythrtmgfhthe cleat andttaehed per-teen. eech side of the nl-if chino. Nothing further ieppensin this perticnlar cycle of operations until the cam Gti begins` to again drivc lever 90 to the left when the operation is repeated. This cycle of operation is repeated over and over until the right hand end of the first cleat is nearly reached when the pin 160 belonging to the, push ineinbcr 170 of that particular cleat assaines a position where it moves plate 242 out of the path ot' travel of dog 152 and prevents the notch :Hl on plate 252 affecting said do;r 152, but on the other hand this pin ltt) ot' the first push mcmber ITU itself engages dog; 152, perhaps at the point where notch 244 would have acted, perhaps at either side of that point. and operates the ratchet key 14-2-145 to sto) the crosshcad in its movement to thc right at exactly the Light point so that thc next staple driven will be at thc correct point adjacent to the` right hand cud of the first cleat shown at the lett hand end of Fig. 1. The cam 10G or other fixed throw actuator, moves thc driving;V pawl in its oscillatingr or reciprocating movement to a tixed extreme position in one direction, but lost notion is provided for between the driving pawl and the can: or other actu-v ator in the opposite direction. They rack 126 and its coperatinpr pawls 142 act as a positive stop to determine the amount of this lost motion and tix the other cxtreme position of the actuator and thereby control thc succeeding step of thc work feedingr mechanism. Members it). which in the present instance `are positioned on the feed chains, are presented successively in correlation with the movement, of the work. which is a particular instance of presentation governed by the relative position of the work and staplingl mechanism at. any particularmomcnt. These members act to brinaV thc drivel'` through the medium of the connecting rod iBS, into cooperating relationship with the stop and the position ot' the` staplesl on the box biank is thus governed. Members 160 act merely as trips in the present instance and the con veyer chains or other mechanism which carry them are not called upon to do any heavy work in positioning any of the dri ving mechanism. but the positioningis cared for by the fixed abutmcnts provided by thcirack which absorb the shock of thechccked moving parts. A continuance of the operation of the machine merely repeats the c vcles of operation just described applying thcm successively to the second. third and fourth cleats of the box material on the machine thus finally completing one complete box blank and cnrryingit to the lct't beyond the machine whereupon they first push mearber of the next oncoming box drives its pin 180 against the arm 228 thus cuttingr the wires which connect the completed box blank with the rcSt of the device and if the cam is present stopping the machine in the manner described.

During the revolution of shaft 54 4in each cycle of operations described the arm is manipulated by this shaft through the mechanism described to keep pushing the box sides up against the fingers 184 and 188,'as the case maybe, thereby insuring their always being' in proper position with reference to the cleats preparatory to sta ling. As this mechanism keeps the box sillias in order and as the spring members 234 keep the cleats in proper position in the manner described, Van accurately formed box blank is produced without any attention :from the operator except to insert the crude material und carrv away the completed box'biank.

By this device 1t 1s )ossible to adjust the push members along t ie sprocket chains to take care of the formation of box blanks in which the successive sides of the box `vary greatly in width and at the same time insure accuratistapling of the parts together particularly insuring the placingv of staples where they are most needed in close roximity to the corners of the box and wi hout running any risk of idly driving sta les in the corners of the box as has hereto oro frequently happened in prior devices.

It will bemoticed that by reason of the fact that the ceats travel upon an independent| track separate und apart from the sprocket chains much greater aecurac obtained than is possiblewhere'the wel t of the cient and box sides has to be carried by the chains, as in the prior art.. In this device, boxes of different lengths as Well as different widths can readily be formed by simply varying the distance apart, transversely of the nnichine of the cut-olf and stapling mechanism which is readily effected by the construction shown and described.

In this machine the use of the band brake 110 serves to take up all lost motion of the parts and insures the accurate.y o ration of the machine in one direction whi e the cross head device 130 with its attached parte, sometimes called the shock absorber, performs the same function in stopping tlmirecton,

parts which move in the opposite these two mec anisms together insuring very accurato operation of the machine and consequently ver satisacto product.
