Michigan, have invented a" certain new and" useful Improvement in Multiple-Head Sta- .plmg-Mach1nes,,of which'the following is aspecification. My invention relates machines in geneal, but' more particularly to machinesforinserting fasteners in sheetmaterial to holdthe same together, and especially tostapling-machines for inserting staples along one corner of pasteboard cartons or boxes, while the latter are still in the form of flat-and folded blanks, whereby these blankscan be expanded into the, shape of square tubes. having flaps which can thereafter-be folded to close the opposite ends of each boxor carton.

Generally stated, the object of my in vention is toprovide a novel and improved construction whereby a plurality of successive fastener-driving-operations may be performed on the work in arapid and economical manner, thereby to reduce the cost of production of the boxes or other articles which require the insertion of staples or other fastening-devices therein.

More specifically considered, the of my invention is to provide construct-ion andarrangement whereby the folded box-blank or other work to be stapled can be fed forward to a position where it will receive a row of staples from the fastener-driving-mechanism, and whereby the work can then be. fed sidewise to receive another row of staples fromfthe same mechanism, so that the two rows of staples will be parallel.

It is also an object to provide certain deobject 'an improved tails and features of construction and combinations tending to increase the general etliciency and desirability of a multiplehead stapling-machine of this particular character. To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

As thus illustrated, my invention. comprisesa frame or body 1 having a horizontal table 2 supported longitudinally thereon,

and provided with parallel rods, 3 extending atfleachfside of said table,a littlev below the surface thereof, said table androds being supported at the receiving end ofthe machine by uprights 4 of any suitable charac-' ter. Transversely arranged sprocket- wheeh shafts 5 and 6 are mounted, respectively, at

the discharge end and the receiving end of said table; and are provided with sprocketwheels forengaging the endless sprocketchains 7 which travel parallel and longitudinally of said table,- T hese belts or chains are provided at intervalsavith cleats or engaging portions 8, whichserve as pushers for feeding the work along said table. The.

' body-frame is provided with uprights 9"and suitable known or desired character.

10which-- provide a support for the horizontal and lo'figitudinalbar 11 upon which the staplers 12 are. mounted, .these staplers bein arranged close together in a straight row? The uprights 9 and 10 provide bear lngs for the'shaft 13 upon which are mountedthe cam-devices '14 by which said staplers are operated, which latter can be of it; straight row of staplers thus. provided is arranged about midway between the two feedbelts'i', and parallel therewith,- and directly above the horizontal and longitudinally extend'ng clencher-bar 15, which latter 1s flexible and secured at one end to the guide- -member 16 which is adjustably mounted on the end of the bar 11," being movable up and down by aneccentric or cam-device 17 having a handle 18 for the adjustment thereof,

- whereby this bar 15 is movable up and down to suit the requirements of the work. The

guide-member 16 is provided with guideslots 19 and 20 which receive'the upper and lower flaps 21 and 22 of the folded blank (see Figs. 8, 9 and 10), so that the two flaps are delivered one on top of the other to the upper surface of the bar 15 during the forward feedingmovement of the work. The

parallel stationary guides 23 and 24 are arranged to extend parallel with the feed-belts at opposite sides thereof (see Fig. 6), to properly guide-the folded'blank into position to receive the first row of staples. The deflectors25 and 26 serve to gradually dethemachine, and is provided with a crank:

arm 30 connected by a r0531 with the bellcrank 32 which is pivoted at 33 on the block 3 1, which latter is adjustably secured by setscrews or in any suitable manner, to the horizontal and longitudinallydisposed rod 36. which latter is in turn supported by the bell-crank 37 and the arm 38, which are pivoted. respectively, at 39 and 10 on stationary portions of the body-frame. This rod 36 isthreaded at 41 to receive the nuts 42 by which theposition of the arm 38 on this rod is changed or varied to suit the requirements. iA spring-43 is secured to the top of the block 34, at 44:, and arranged to beardown upon the work, so that the flaps of the blank will be held one upon the other as the work travels forward to the stapling position below the-staplers. A spring 45 connects the pivotal point 46 of the rod 31 on the bell-crank 32 with the bracket 47, so thatthe lower end-portion 418 of this bell crank (this end-portion 48 serves as a. stop for the pusher 8 on one of the feed-belts) tends to remain in normal position ,(seeFig. 11), andwhereby this bell-craiikis movable from -this position against the tensionof said spring. An arm -l9'is also pivotedat'33,

and has a. short arm 50 provided with fa. pin

51 which engages the upperend-portionof" the bel l-crank 32 (seeFigs. 11 and 13),.a'nd V a 'roller'52 is mounted at the end 0f the arm '49 to bear upon the Work, being disposed above a slot 53 in t'heftable;immediately outside of theouter feed-.beltfiliThe rod 36,

square'to prevent, rotation of he block 34 thereon. but is cylindr-ic where is threaded at 4.1 for the adjustment pr viousl -(1e;

scribed. When the two layers orthickness'es 51 and 55 of the folded blank aref fdrc'ed forward by the feed-belts toa aoint w'here their forward edges extend undervth roller 52' (see Fig. 13), the arm'49 will be raised,

and the pinwil will tilt the bell-crankl32 into such a position that thestop 48 will bedirectly in the path of, the pusher 8"which is propelling the blank forward at the. rear edge of the latter. When the pusher Sengages the stop 48.. the bell-crank'32 is then tilted about its pivot 33 (see Fig. 16),; causing the rod 31 to pull the arm 30 toward the 115.

staplers, causing the shaft 2910 be rocked in its bearings. For this purposefthe rod 31 is provided with an adjustable stop 56 for engaging the arm 30, but, which permits the rod to slide in the end of'the arm'fith in the opposite direction, without producing move ment of this arm. 'Saidrod 31 is also pro- Yldfl at its end with a handle 57 by which it can be manually manipulated to control the machine in certain ways. The shaft 5,

it will be seen. extends across the delivery end of the machine, and is provided with a clutch 58 which controls the transmission of power to this shaft from the .worm-gean. ing 59, the latter being operatedflby spun gearing which is in turn operated'by' the sprocket-gearing 61 mounted in suitable which has its sprocketchain 62 connected, witha sprocket on the main drivingshaft 63, the latter being bearingsat' the top of the body-frame, whereby this main shaft extends parallel with the feed belts. rock shaft 29, which is parallel with and immediately above the sprocket-shaft 5, is provided with an arm 64 which is connected by a link 65 with the toggle-joint-connection 66' between the pivoted clutch-shifter 67 and the stationary bracket 68, the arrangement being such that when this toggle-joint is raised, the shifter 67 operates to close the clutch power from the shaft 63 through the sprocket-chain 62, through the gearing 60 to the worm-gearing 59, and from the latter through the shaft 5 to the two parallel feedbelts. On the other hand, when this togglejoint 66 is depressed (see Fig. 17), said clutch is-then opened, thereby stopping the operation of the feed-belts. The opening of the clutch 58 occurs when the pusher 8 engages the stop 48, for the reason that this produces a pull onv the rod 31, which causes the arm 30 to rock the shaft 29, thusdepressing the arm 64 and causing the toggle 66 to operate the shifter 67 to open the clutch. This stops the work directly beneath,the staplers 12, in position to receive the first row of staples, which latter are to' be inserted through the two superimposed thicknesses of the blank.

At the same time that the automatic forward feed pf the work is interrupted, in the manner described, the operation of the staplers 12 is automatically started, and the arrangement for doing this is as follows:

Assuming, for convenience of description, that the machine is already in operation, a cam-device. 69 on the stapler-shaft '13 has a vertically reciprocating connection 70 to the lower end of which the shorter arm of the bell-crank-lever 37 is pivoted at 71, so

that this cam-device serves to reciprocate the rod 36 when it becomes necessary to raise the stop 48 out of the path of the pusher 8 on the feed-belt, thereby to permit said pusher to pass said stop after the two rows of staples have been driven. \Vith the arrangement shown, the stop 48 is raised each time the staple-drivers-move downward, but this is only, effective after the second row of staples has been driven, as will hereinafter appear. This connection hasan opening .72 which engages the end-portion 73 of the lever 74, which'latter is pivoted on the frame at 75, whereby this lever is tilted about its,

pivot when the connection70 moves up and down. The" other end of this lever 74 is connected by a link 76 with the arm 77 on the short shaft 78, (see Figs. 4, 5, 20 and 21) and a ratchet-pawl 79 is'pivoted on this arm to engage the ratchet-wheel 86- (provided The .thus tilting the lever 58, thus causing a transmission of lever 74 is tilted. about its axis to draw the dog or pawl 79. backward over the ratchet-wheel 80, a-band-brake 81 serving to hold the shaft 78 against rotation at this time, lVhen the staple-drivers move upward, the connection 70 also moves upward, 74 in the opposit" direction, causing the pawl 79 'to move forward (see Fig. 5), thus turning the shaft 78 one notch. The cam 82 is fixed on the shaft 7 8, adjacent ,said ratchet-mechanism, and is formed with th ree equidistant -projec tions for engaging the roller 83 on the member 84 which is slotted to reciprocate on the shaft 78, this member 84 being connected by a pitman-rod 85 with .the pivoted arm 86, which latter is pivoted at 87 upon a stationary portion of the machine. This forward actuation of the ratchet causes one ofthe projections of the cani. 82 to engage the roller 83, thus producing an upward movement of the rod 85, feed-device or shifter 88 is'operated by the pivoted arm 86 (the shifter 88 is disposed in line with the guide-'23 to bear against one edge of the blank), and whereby the blank is shiftedsidewise under the staplers.

The.

actuation of the pawl 79, by partially ro-- tating the shaft 78,'serves also to rotate the wheel 89, which is fast on said shaftfso that the three notches of this Wheel (see Fig. 22) assume an intermediate position relative to the. projection 90 on the upper edge of the pivoted arm 91, the latter being pivoted at 92 upon the stationary portion of the machine. The shaft 29 is provided with a laterally extending arm 93 connected by a link 94 with said pivoted arm 91, so that when this shaft 29 was rocked by the rod 31, in the manner previously described, the arm 91 was pulled downward to disengage the projection 90 from one of the notches of the wheel 89, thus unlocking the shaft 78, and at the same time closing the clutch 95 which controls the transmission of power from the main driving-shaft 63 through the gears 96 to the stapler-shaft 13. thereby starting the operation of the staplers. It will be seen that this clutch, which may be of any suitable character, is connected by a link 97 with the lever 91, so that said clutch is closed to start the staplers when the shaft 29 is rocked by the engagement of the pusher 8 with the stop 48 previously descriliwd. Now when the staple-drivers move upward (after driving the ing the partial rotation of the wheel 89, the connection 70 operates the bell-crank 37, as previously explained. thereby returning the stop 48 from its raised position to a.posi-', tion behind the pusher 8 (see Fig. 14), and

Also, at

this time (whilev the stop 48 is in elevated posi tion), the clutch 95 is held closed and the the roller 98 which engages a cam 99 on the shaft so that the staplers are retained in operation and the rock-shaft '29 held by the said roller and cam against rock ing backward to close the clutch 58, for the 95, which controlsthe transmission, of power:

from the gearing 96 to the shaft 13 (one of the gears 96 being loose on theshaft 13 is this key 1S actuated by its spring, it engages the loose member of the clutch and closes the gearing and a well-known form of 100 has a beveled porthe key 102,- (see Fig.

The lever tion 103 for operating 3) -and when the shaft 29 was rocked by engagement of the pusher 8 with thegstop 48, as. previously explained, the lever-arm 91 was pulled downward, and the lever .100 was tilted topermitthe bevel 103 to disengage the bolt 102" (see commences to rotateiinmediately (see arrows -in Figsi 7, 22 and 23), andthe cy-lindric 'p'eri heral 'portion' of the cam 99 continuestoholdthe roller 98 in the position shown 5o. way between two I notches I f 'the wheel 89, whereby the arm :tation. of the shaft a position opposite timethe projection=90 on'the arm 91 is midin" dotted lines in Fig. 23, so that the clutch 95 is retained closed, a'n'd whereby the clutch 58 isretained open.

and this again tilts the lever 74 'nto the position shownfin Figs. 19 and 4, so that thepawl 79 is retracted on theratchet-wheel '80, and wherebylthe stop 48 is again raised out of engagement with the pusher'8 (see dotted lines in Fig. 16), but at" this time the roller 98 is by the engagement of that the ratchet wheel 80 and 9 Fig. 22 and dotted lines ,in Fig. 28),.thus closing the. transmission of power'to the stapler-shaft.

thus 'causingjthe hlfter or sidewisefeed device 88 to move away from the feed-belts.- The gap 104 inthe cam 99 receives the -roller 98 and thereby. causes the opening ef'the; clutch at about the time the staple-drivers reach the limit 0t their upward movement, thus openin' the clutch 95 and stopping the, operation of the staplers. \Vhilethe stapledrivers are moving upward, after driving the second row of staples, the stop 48is return ing to its lower position, but the relative arrangement of the parts is such, as previously-explained, that said stop comes down immediatelybehind the piisher 8 (see Fig. a 14), and this time the clutch .58 closes, thus permitting the feed-belts to move the 'sta pled'work-ahead and at the same time bring I 1,90

WVhen' vacant or unoccupied spaces on the 52, the latter feed-belts pass under the Iroller drops down, and at such time, of course, no staples are driven and the stop 48 is held in such position that the pushers8 pass unde'r, and the feeding movement is not interrupted until ablankrais'es the roller thus lowers the stop 48 into the path of the next pusher. v

T he staplers, of course, can be of any suit able, known or approved character, and. are provided with feed-devices 106 the wireffrom which the staples are made, a these devices being mounted on the transverseshaft 107 arranged behind the staplers. This shaft is provided with a ratchet-feed device. 108 which is operated by the recipro- 125 eating pitman 109, thelatterbeing connected with a member 110 which is slotted to 'reciprocate on the shaft 13-, like the device 69,

the next pusher 8 k 95 will be closed to 1 for feeding blank of the box is folded .in-a manner to driver is moved downward. When the pitman 109 moves upward, the ratchet 108 is thereby actuated to operate" feed-rolls of the devices106 for feeding the wire to the staplers. The member 110 has a roller 111 which engages the cam 112 on'the shaft 13,

(see Fig. 20) so that the pitman 109 is actu eccentric groove Ofyth cam 115,. wherebythe connection 70is,actuated both upward and downward in a positive manner, by said earn 115, therebyto rock the bell-crank 37 and the lever 74, in the manner and for the purposes previously described. A handbrake 116, of any suitable character, is applied to the shaft 13, thereby to prevent rotation of this shaft after the clutch 95 is opened, and whereby the staple-drivers will always be stopped in their retracted or high.

, est position.

The guides 23 and 24, it will be seen, are secured to the tableb'y devices 117 whiclr are adjustable along' 'the' transverserows of I i by the attendant or operator'at will. This holes'118 in" theitop', of said table, so that the distance betweenthe guides can. be changed or varied at will,tliereby to acco'm-', modat'e box-blanks or the like of various widths. As shown in F igs; 8, 9 and 10, the

bring the flat or narrow side-wall 21 immediately above the flap. 22, andthe {first row ofstaples, it will be seen, is driven along the edge of the flaplor side-wall 21, and the second row is driven insideofthef first row and" through the two thicknesses, in such manner that this s'econdrow extends? longitudinally of the-box andfp'arallel with the other" row and 'c1ose to the edge of the "innerjflap-22', so that the two ends of the? blankare connected together by a double 7 row- 9f staples. -iWhen the flatwise folded blank is" pushed sidewi se, by the shifter or sidewise feed-device 88, lin', the manner previously described, for the driving "of the second-rowfof staples, the outer edge of the blankmay move over a distance until it enr gages the guide 24, if the blank is narrower than the distance-between the two guides On. theother hand,-if the guides have been "set to the exact width. of the blank when.

folded flatwise,";=so that both edges of the blank bear against the guides, the 'sidewise shifting of the blank will then cause a slight buckling .of the sheet-material along the I longitudinal fold-lines thereof,' at points between the staplers and the outer guide 24, thus permitting the flaps 21 and 22 to assume the desired position. for the secgpd row of staples. Or, as shown, the guide 24 can be formed in two sections, and the section oppositethe staplers can be positioned a little farther away f.rom the staplers than the other sections,'th'us permitting free sidewise shift of the work after the first row of staples is driven. The folded blanks are fed to the receiving end of the machine by hand, and

in such manner that the flaps 21 and 22, will properly enter the guide- slots 19 and 20,-

in the manner previously described, After the driving of the second row of'staples ,.the

'feedbelts are then automatically started, in the manner explained, and the stapled. blank 1 so is discharged from the other end of -the machine at the same time that another blank or a fresh piece of work is brought below the" 1 staplers.

As a matter of convenienceforthe openator, a foot-pedal 119 is provided anthersceiving end of the machine,-at thebase of the uprights fl, and connected by a pull-rod 120 with the bell-crank 121 pivoted on thebody frame at the other end of themachine. This bell-crank, which has its two arms separated on the rock-shaft 122, is connectedhy a link I 123 with the clutch-shifter 67- which controls the clutch 58 (the spring 124: on theshaft 5 exerts its pressure to (3 058 this clutch), so that said clutch can be opened and closed clutch may be of any suitable construction,
