art after having obtained an understanding vof my invention from the disclosures herein made, that my invention is capable of niodiication without' departing from the scope and spirit o'f the invention, and I wish it to be so understood. p

The particular machine shown in 1the drawings was designed for. stapling boxes cfa type which are folded up from blank 'sheets of cardboard, the adjacent edgesof which are brought together and stapled or otherwise fastened. These boxes. `as is well known, are formed by cutting a blank sheet of .cardboard or Asimilar material to the and the blank sheet proper size and shape isthen scored along definite lines`- so that it may be folded.

In lthe drawings, particularly Figs. 2 and several of these boxes in the stage of their formation4 in which the stapling operations are performed upon them. The blank cardboard is folded upon itself so that the parallel edges (1) overlap asyshown in Figs. 2 `and 2a, to form a longitudinal seam'alongwhich the stitching or stapling is done. The stapling operation is preferably performed while the blank is folded in the manner shown in Fig. 2 in v i the machine, thatis to say while it isflat, and after the seam has been stapled the folded blank is opened as is well-known, so that a box rectangular in cross section is formed. The blank is cut so vthat after the box has been formed into a. rectangular section there still remain the end liaps (2) which are adapted to'be tucked into the ends of the box to close the endsthereof. The staplingof the seam takes place over a length which corresponds to the overall.

length of a completed box, that is after the end fiaps are tucked in. Thus it is obvious that while the box is in the fiat condition shown in the 'drawin s, the end flaps (2) project beyond the en s y(3) of the seam to In Yother words, the stapled seam is substantially equal to the length between the -points (3) in Fig. 2*?. No further description of these boxes and the method of forming them is necessary as far as my invention is concerned. The staple fasteners (5) are preferably positioned at equal intervals along the seam, any number of these staples being used as desired. A single row of staples# is found t'o be suficient .along the entire length of the seam but for the purposes of reinforcement it is sometimes desirable to place anextra staple (6) at each end of the same, but of course this is not necessary.

My invention'is not concerned with the stapling mechanism per se, and this mechanism may be of any suitablev type for the purpose. In the drawings Iliave shown a stapling head (A) which needs no particular description except to say that it operates intermittently to apply staples to the seam.

' It is necessary therefore to feed the boxes in relation t'o this stapling head so that the staples will be properly applied along the' seam, and in the construction shown bI feed the boxes intermittently in timed relation to the operationof the stapling head, 4so as to equally space the staples along the seam.

, In the construction shown this is done by means of a pair of parallel'traveling chains (7) spaced apart and traveling in ,slots (8) in the upper face of a suitable bench or table (9) disposed beneath the stapling head and in proper relative position theretorf lThis table is supported in any suitable manner as by means ofthe frame (B) shown more clearly in Figs. 1 and 3. These chains are preferably in the form of continuous loops which extend the entire'length 'of the table and travel around sprockets (10) carried by suitable shafts (11) and .(12) positioned transversely beneath the table. The chains lie preferably substantially flush with the top surface ofthe table but they have risers or pushers (13) which extend above the sur face of the table and are-adaptedv to engage the boxes and carry the-boxes along the top ofthe table. Fig. 10 shows in detail the construction of the chain and these pushers. The chains 'are preferably of the link:` type7 .but the pivot pins (14) by'whichthe several links (15) ofthe chain `are fastened together,

extend laterally beyond the'width of the chain, so as to provide a convenient means for attaching -thepushers to the chain. These pushers'are c arried by' small frames' (C) whichare constructed so that they may be attached tothe chainsA-at any point, thus enabling the boxes to successively follovs7 each other in any desired spaced relation. Each of these frames (C) comprises two side 4 plates (16) and a pair. of cross bars 17) rigidly secured to the plates to form a rigid frame. The side plates (16) veach have a pair of notches (18) .for engagement with the outstanding ends (14) of the link pivot pins. VThe forward notch (18) of each side plate opens in adirection longitudinally of the chain,v while the rear notch (18a) of each side plate is disposed at an angleto the forward notch (18). The frame (C) thus spans the chain and it is necessary in order to place the frame in position on the chain or remove it therefrom, to tilt the rear end of the frame upwardly or at an angle to the longitudinal line of movement of the chain.

resting surface for the In other words, to attach the fram-L; (C) t'o the chain it is necessary to placa artilt the frame at an angle to the chain and push the forward slot (18)into engagement with the pins (14) and then rotate the rear end 'of the frame downwardly toward the chain about the pins (14) until the rear slots (18a) engage the corresponding pins (14). To remove the frame this operation is simply reversed; that is t o say, the rear end of the frame is swun u awardl i about thev forward g end as a pivot until the rear notches (18a) are free of the pins (14) and the forward notches (18) may then be withdrawn from engagement with their corresponding' pins (14). This construction provides a suitable and simple means for adj ustably positioning the pushers. (13) at any point along the chains. pushers (13) rise upwardly substantially at ,right angles to the chain, any pressure against the forward face of' the pushers incident to the pullingof the boxes along the table, will tend of course to'hold the frame (C) in tight engagement. with the chain.

It will also be'noted=that since the 'i In attaching the pushers to the frame' (G) it ,will be readily seen that .the pushers are simply positioned between the side plates '(16)' of said frames and the cross bars (17 pass through the lower part of said pushers. If desired, the rea-r ends (19) of the pushers may be extended some distance in the rear the side plate (C) to form a tripping pin -I (17%). These tripping pins (17a) are adapted tobe extended beyond either side of the chain in acordance with the requirements of a controlling [mechanism hereinafter tol be described. Thus it will be seen that the pushers (13) and the controlling frames (C1) may be adjusted along the chains (7) to adapt the machine to any desired space between successive boxes or to adapt it to different sized boxes'. It isfdesirable in a machine of this character from the standpoint of eiiciency to feed the boxes to the stapling head in a's rapid succession as possible, and also to propel the boxes'at a greater rate of speed between Athe points where the stapling head stops stapling one box and begins on another. In the present construction, I intermittently feed the boxes i during the stapling operation and then propel the boxes by a long continuous step until the point at which the stapling operation on reducing the pleted box to she succeeding box is to begin. In other words, the chains travel by short intermit tent steps during and in timed relation to the stapling operation, and in a long continuous step between the' stapling operations, thusv time necessary' for .the combe removed and the Succeeding unstapled box to be brought into stapling position. I accomplish these results by driving the feed chains (7) inthis manner and I will now describe the mechanism by which;

this -variable intermittent movement of the chains `is brought about. L p

Thel stapling head (A) is carried at thc endof al horizontally disposedarm (D) forming, in a sense, a continuation .of a vertical pedestal (E) positioned atl one side'of the table (9) as shown more clearly in Fig. 3. Extending through this -arm (D) is a horizontal shaft by means of which pouir is transmittedto operate the stapling i (D) and its outer end is supported in a jour- (3.0 and 31) are v lthe opposed member (30).

mounted on the end yof a ho'ri- (27) outstanding from said Loose on the shaft is a large nal arm (26) zontal -member pedestal (E).

.Y pulley (28) which is driven from any suitable souce of 'power by means of a belt (29). On each side of this pulley is a clutch. The clutch (F) maybe of any suit-l able type for the purpose but in the construction shown it is composed of two opposed members (30 and 31). Both members loose on the shaft, but the member (30) carries a sprocketwwheel (32) and the member (31) is fastened to the pulley wheel (28) in such a manner that it may be shifted into'and out of engagement with y Thus when the member (31)l is in engagement with the member (30) the pulley wheel will drive the sprocket( 32), and when out of rengagement with the member (30), the sprocket is free to rotate idly. The clutch member (31) is shifted by means of lever (L) (see Figs. 3, 5, and 6), which is fastened on a 4rock shaft journaled at 34 inthe upper end of a bearing standard (34), the shaft serving as a pivot for the lever. embrace the clutch member (31) and has pins entering a groove in said member (31) so that said lever can shift the clutchmember and still allow it to rotate. The rock shaftA which carries the lever (L) also carries a depending arm (35).V The lower 1 arml of the lever (L) has a horizontal cern this clutch per se, but only in ycom- This shafty extends beyond the arm is pivoted at This lever is forked to- -a longitudinally slidable member (38) which normally engages and locks the other mem- Aber (39)-of theclutch. This member (39) l of the clutchis fastened to the pulley so that when the two members (39 and 37). of the clutch are locked together, the pulley will drive the shaft (25) and hence the stapling head, and when said members are dis connected by the shifting of member (38) the shaft remains stationary. The member 38 has a beveled face and is positioned in a groove between the two members (39 and 37) in the path of a dog (40). The dog (40) 41 (see Fig. 5) on a'ixed arm (42) and its free end is adapted to be swung into and out of the groove. )Vhen it is swung into the groove. itsI end engages the member (38) vand shifts. itto thereby unlock the clutch members (3,9 and. 37) and stop the stapling head, and when said dog is swung out of said clutch free of member (38) the member (38) operates to lock the clutch members and 37) together and thereby drive the shaft The details of this clutch mechanism are not shown in `accomplished by a vertical rod (44) the upper end of whichiisv' pivotally connected to the dog and the lowerend of which as shown more clearly in Fig. G, loosely passes through a hole in the. end of the lateral extension (3K6) of lever (L). Beneath said extension the rod carries a couple of nuts the drawings and fon-the purposes of this llO which are adjustable along said rod,

for the purpose of adjusting the parts. A'

spring (4G) is connected at one end to the rod (44) and at its other end to a fixed mem ber or hook (47) on the frame, so that this ,l

spring tendsto hold the dog into the clutch and thus maintain the stapling head station ary, and when the rod is pulled dmvnwardhagainst the tension of the spring, the stapling headwill be operated.

The two clutches F and Gr are arranged so that they both cannot be in locking condiT tion at the same time. That is to say. by reference to F ig. G it will be seen that when the clutch members (30 and 31) are blaced :aimeel i. to the line of movement of the chain. The

1 (17a). They are spaced apart laterally in .l5

such a manner that when the c ontrolling .pin

(17a) on one side of the chain (7 strikes fone'of the cams, it'shifts'"`the plate '(77) transversely .and at the same` time places-the operationA is aboutto begin on the seam -ofa boX, the controlling pin (1711) corother cam iii-position to be engaged by the succeeding' pin- (17 a) on the other side of the chain. --Thissucceeding-pin operates to shift 'the plate. (77) inthe', opposite direction.

Thus the plate (77) is given a reciprocating movement by the controlling pin (17u). The

.plate (77) is connected with thearm (85,)

ofthe clutch shifting Vmechanism by Vmeans of alin'lr v(82) (seeFigsjBf, 8 and 9) so that the reciprocation of the plate (77) rocks the'clutch shifting lever (L) in the corre- Spondingdirection. Thus when the stapling end of a responding thereto, rocks the clutch shifting z lever (L) inthe direction to throwthe clutch' .G and start the stapling operation, and also the intermittent movement t`o the chains (7) This'opens the clutch F and allows the continuous driving chains to travel idly. When the stapling operation is to cease, thepin (17a) on the `opposi-te side of the chain (7 corresponding to the end of the seam throws the operating lever (L) in the opposite A should be no box in position to receive the direction,allows the clutch G to open andc-loses the clutch F, thereupon ,shifting the continuous driving mechanism into operative relation to the chain (7), and the intermittent driving mechanism, although still operating the pitman'and ratchet, will have no effect on the shaft (ll) and the chains (7).

It is desirable to avoid the operation of the stapling head in the event that there staples, and I therefore provide mechanism by which the stapling operation is controlled by the boxes to be stapled. Referring to Figs. 3 and 6 it will be seen that the link (82) carries on its end-a plate (83) having an L-shaped slot :(84) one 'leg ofwhich isv disposed horizontally and the other leg vertically. This slot coperates with a pin (85) on the endr of the arm (35). The plate (83), however, and hence the end of the rod (82) arefpivotally connected to and suspended from a link (86), the upper end of which is piyotallyaconnected to one arm of a bellhence'raises the wheel (92) the.- link through the lmedium of the parts just de- .the- -shaped slot (84), im (17a transmit .crank lever (87). This bell-crank lever is of the boXes in sucha manner that, as a box"l passes beneath 1t, 1t engages and raises the" wheel and `thereby rotates the bell-crank (90) about its pivot. If there is no bonA in position to receive vthe staples when the sta-- pling operation Ashould commence, the wheel (92) ofcourse remains idle.. Thus when a box is in position to Vreceive the staples and (86),.

scribed, depressesthe'plate (83) and causesl the in to occupy the vertical leg of` and hence when the 'shifts the rod (82) this rod will motion to the clutch shifting lever (L),the pin .(85) and thevertical portion of the slot (84C) acting as a rigidl oivotal connection. Should the box be abs'enh from its position the rod (82) and hence the plate (83) will be raised by means of a spring (93) attached to the standard and to rod (82) and cause the pin (85) to occupy the horizontal portion of the L-shaped slot (84).

Hence when therod (82) is longitudinally shifted there will be a lost motion connection` between the rod (82) and the clutch shifting lever (L), and hence said clutch shifting lever will not be operated. v This of course also has the effect ofleaving the continuous driving mechanism in operative 4relation to the chains.(`7) until a box does arrive in position.

It is desirable' torbe able to stop or start the machine, oftentimes in the middle of a stapling. operation, but under such conditions it is also desirablevthat when the machine is again started it will continue the particular operation at whichit left off. 5F or instance, suppose that the machine should be stopped when a boX is only partially stapled when the machine is again started it will Acontinue the stapling operation; or should the machine happen to be stopped in the act of driving the lchains (7) by a continuous movement, it is desirable then that the machine will complete said cgntinuous movement to finish out the cycle of operation. As shown by the dotted lines in Fig. 6,. it will be seenA that the clutch member (3l) and the It is desirable then that `Wedge-shaped end of a plunger Whenever the arm (35) is'swung toshift l (96), so to speak, and thus the plunger, in` 15 X tion of the clutch, the arm (36)v will occupy such a position tha-t the clutch operating dog (40) will -be in the groove and Will maintain the pulley and sprocket Wheel dis-` connected fiom the shaft. In this position of the parts, the feed chains (7) will, ef course, remain idle.- As shown in Figs. 6 and 12, the'lower end of the arm (35) has a Wedge-shaped piece (95) which is adapted to cooperate with the correspondi(ngl)y 9G the clutches it must snap past the plunger a sense, forms a sort of snap lock to hold -the arm' (35) on either side of its center.

This plunger, however, is slotted, as shown in Fig. 12, to provide a guideway for a .Y-shaped member (98).' This Y-shaped member is carried on the upper end of a rod (100) and is yieldingly held normally in its lower position by a spring (101) positioned `on the .rod (100) between a portion of the frame and a collar (102) on the rod. The faces of this vmember `(98) are inclined in the .opposite direction to the faces of the plunger member (96) and at the same angle as the faces of themember (95). Thus, by pushing upward on the rod (100), and raising the (Y) member (98), one of its faces willcoperate with the corresponding face on the member (95) and by a sort of cam or Wedge action will rotate the arm (35) untilthe point. of the member- (95) almost but `not quite vlpasses the point of the plunger member (96). In this position the clutch member (31) will vbe in its neutral position before described and the chains (7) Will stop. It might happen that the machine Was thus stopped when the stapling operation on a box was only partially completed and of course it is desirable [when the machine again starts that it will continue the operation which it Was last performing. Thus when the (Y) member is released and Withdrawn by its spring, the

spring pressed plunger (96) will act against the face of'the'member (95) and return the arm (35) to its original position. This action occurs Whether the member 95) be on one side or'the other'of the plunger .member (96) when the machineis to be stopped. Any suitable means for. operating the (Y) member (98) may 'begemployedl` In the present co-iistruction I provide .a bell crank .of this latter bell crank leverzis connected by a link (108) to a foot treadle (109) Which Y is located in a convenient position for the operator to manipulate with his foot. In this manner the stopping and starting of the machine may be4 controlled by the operators foot and each-time the machine is started it Willcontinuethe operation at which it was last stopped.

When the clutches (F and Gr) are shifted to bringthe contacts and intermittent mechanism into connection With the chains (7) there may be provided on the shaft (60) a suitable brake. In the construction shown more particularly in Figs. 3 and 5,A this brake may comprise-a brake Wheel (60a) acting o-n a shaft and surrounded bya brake belt (60h). The. ends ofthe brake belt (60h) being connected on thevarm (60) in such a manneras to exert friction on the brake Wheel (60a).

- As theparticular form of the brake is not a part of the invention, further detailed description thereof seems unnecessary.l
