STAPLIN G-MACHINE v Specification of Letters Patent.

Patented June 22, 1909.

r plication filed December 9, 1907. Serial No. 405,823.

clear, and exact description, reference being had to the accompanying drawings. forming part of this specification. I

My invention relates to macliiins designed to form and secure by wire staples to the interlockingflaps of paper vessels, the tin strips that are employed in locking the covers of paper vessels in place.

For certain constructions of paper vessels used temporarily for oysters, berries and the like, in the sale of grocer-s goods, it has been customary to employ for locking down the integral covor of the bucket, a tin strip or tongue secured to one side edge of the cdver, and arranged to be inserted and locked through an eyelet or loop on the other cover. These tongues or tin strips are purchased cut into the proper lengtl'i, with a hole punched-through one end, and an eyelet ma chine has been used to fasten the strips in place. These eyelets also have to be-purchascd in large quantities, they are necessarily small, and the machine frequently fails to catch them properly, so that they are wasted. The tin strip is held by the eye let alone, and if tho outside fold of the bucket and cover becomes loosened, the tin strip falls oil, and the bucket cannot be used. The eyelets vary in size somewhat, and the holes in the tin strips are not of exact uniform diameter, consequently, when the eyeletis reanied, if the hole in the tin strip is too large for the-eyelet, the tin strip will not be held, and the entire pail mustbe thrown away. In thus securing the tin strips by eyelets to the paper pails, a nuni her of different: operations are necessary, so that the output oi: any operator per day is lvloreovcr, when 4 the necessarily limited. tin strip is fastened with the eyelet, it can rotate on the eyelet, and very frequently the tin turns down between the folds of the cover, so that. it cannot be gotten at, or being outof' sight, the bucket is thrown away as defective. Then, the securing is i'ieccssarily a dangerous operation, as the parts are small, and the hand of the operator is very apt to get caught in the machine.

carryin g it is to overcome these objections to the ordinary -method of securing the locking tongues to the covers of oyster pails, and the like, that my invention is directed, and it" consists of that certain novel construction and arrangen'ient of parts in the machine to be hereinafter particularly pointed out and claimed, in wh ch the tongues or tin strips are fOlll'lGCllIl the machine itself, and the material for the strips is furnished in coils, or

rolls, and instead ofsccuriug the strip by an eyelet, Wire is furnished from a roll, and staples formed in the machine, by means of which the'strips are stapled to the bucket cover in send-circular cuts formed on the sides of the strip. Instead of the strips being secured-by a reamed-over eyeletto one fold, the tin is fastened securely by the staple through both folds of the cover, and

ifone fold is torn out, the tin-is still fastoned to the bucket cover, and can be used. In addition to this, while the tin strip thus stapled has a swiveled movement, so as to permit its ready insertion through the looking loop or eyelet, the strip can no longer 30 rotate, and cannot drop down out of place.

In the drawings, Fi ure ,1 is a front elevation of my improved machine. F1g. is a side clevation'of the same. F1 3 1s a front elevation of the upper part; of the nmchine, with the cam plate and attached parts removed. Fig. 4 is a rear view of the mechanism for feeding the tin strip. Fig. 5 is a cross section of the machine taken on lines 5-5 of Fig. 2. Fig. 6 is an enlarged vertical section of the staple forming, driving and clenching devices. Fig. 7 is a perspective View of said staple forming and driving devices. Fig. Sis a. detail elevation of the punches for cutting the tin strip. Fig. 9 is a plan of one of the tin strips detached from the pail;

1 is the frame or standard for supporting the operating mechanism, provided with a pillow block 2, secured to an extension of the base, in which is journaled the shaft 3, the fly wheel pulley 4, running loose on the. shaft, and connected thereto by the clutch 5, and by means of which ulley and belt (not; shown) the machine is riven. Mounted on this some shaft 3 is the cam (3, and the crank disks 7 and8. The crank disk 7 is connected by therod 9 with the vertical moving slide 10, which slides in waysill' in,

the upperframevvork '12 of the machine, f

which framework is securely bolte standard 1.-

the head 13, bolted thereon, and this head carries the depending cinn arm 14, which cam i; engages a roller mounted in the upper end of an anvil lever 16, pivoted at about its middle pointon u lug 18 on the cum plate 19 secured to the frame 12. A spring it? bears between this anvil leyer and the side oi. the frame, so that as theslide 10, with its head 13 and coin arin Ll, is moved downward, the rolleuliion this lever will be forced into the euthway portion of the cum, and the lower or anvil end of the anvil lever will be shifted forwardly. around the lower end of this anvil lever that the staple is formed, This staple forming and driving mechanism is illustrated in Figs. 3,6 and 7.

Mounted on, and depending from, the head 13 is the bifurcnted'slidc or former 2t).

This bifurcated slide 29 rides in a slot Z -l in the framework 12, and is carried upward by the pin 21 on the slide plate 23, which at its upper end is secured. to the head 13,. and which slide plate 23 carries the driving member 22 a part thereof, and which member is projected between the forks of the former v 20. The former 20 is normally hold down by the spring 25, and locked in "tlliS position by the dog 26, pivoted on the head 13. The head 13 also carries ndjustribly attached thereto the depending plungerQ'Y, which carrics the punches (Fig. 8)- 29 and :36, which enter the openings 30 and 31 in the die plate 23, which is horizontally mounted in the frame of the machine. The punch 29, which is employed forsevering the tin strips into the proper lengths, as. will be heroin-aliter described, is beveled off, so as to only cut at the back edge of its opening in the die plate, while the two'similurpunches are squared attire bottom to cut semi-circular notches on each edge of the tin'strip, shown at 32 in Figs. 5 and 9. 33 is the continuous 'strip of tin furnished for the machine in a roll, or coil 40, mounted to rotate freely on n arm extending out from the (lord l. 5- between. the teed roller 38, mounted on the shaft journeled in the. frame, and underneuth the pressure roller l1, which bears on the feed roller. The shaft 35 carries; the v ratchet 3,7, which is engaged by the pawlf36, mounted on the lever 34, which is pivoted on the shaft 35. The outer end. the lever 34 is connected-by the connectingiod 33 with the crank disk 8 at-the bottom of the machine, so'that with the rotation of the shitft 3, the pawl 36 will be actuated. rotate the shaft- 35', to feed by means of the I feed wheel'38 the proper length of tin strip .to the machine. 'lhe pressure roller all. is geared to the feed roller 38 by the gears .42, 43, end this pressure roller 4C1 is mounted.

'lhe slide 10 is provided'with This strip 39 is passed to partially d to the l in the rocking plot will be hereinafter described.

6 ll, which is pivoted to the frame 12, and kept in contact with the feed wheel 38 by the pressure of the spring" I l6 bearing on the vertical arm 45 on the plate ll. p 6-1 is a prcsser foot secured on the frame 12, which bears on the tin strip, as it is fed along over the die plate 28 to hold the same in place.

The wire from which the staples are formed is mounted on the reel 62, journaledon th i arm 63, supported by the standard, till llS wire is fed between the feed roller 1 pressure roller 64, journuled in the frznne 12, the feed roller-58 being provided 30 with the ratchet wheel 59; 57 is a hook depending from the head 13, which engages the teeth of this ratchet on the upstroke, and thus feeds forward to the nmchine the proper length of wire. s5 Immediately underneath the staple driv ingmcclnuiism is a block 65 mounted on the standard, and provided with a recess 53 in its upper face. 54: is a plunger which rides through this block 65, and is actuated by the rod 66, coupled to its lower end. The lower end of this rod (36 carries the roller 55, which is engaged by the'cani disk 6 to raise the rodnndplunger at the proper time for clenching the staple, and G7 is a coiled spring bearing between the block 65 and the shoulder on the rod 66 to return. same toits normal position, soon as it is'released,

by the cam. i

In the operation of the machine, the coil of wire and the. tin strip roll being'mounted iiithe nrnchinemnd fed to the feeding dd wines, the driving shaft 3 is set in motion, and the crank disk 8 being in advance actu: ates first the connecting rod 33 to operate the tin strip, feeding device, and to feed for- .Witl'tl under the die plate the p'roperlength of strip, the notches 32 32 in the strip,.as shown in Fig. 5 having been out in the. previous operation. The paper bucket to which the. tin strip is'to'be attached is then fed over the die plate Witlrthe tin strip 46 preferably between the two thicknesses or. folds of the pail. The crankdisk being later in giction than the emnlr8, then pulls 5 down on the rod Q fQrcin the head 13 downword, and as the edge of the fork 20 passes the cutter plate 48, the-wire'l-tl is severed from the roll, and the severed end i isforced down by the forks 20 oventhe end of the- 2 .zn vil lever 16 forming-a staple. As soon as this staple'is formed, the pin 50 on the dog- 2G,whieh-rides in the. slot 51 in the plate 19,'bo1tc'd'to the frame 12, shifts the dog't'o release the bifurcated slide-20, a 13 continuing its downward stroke, the driver 22 is forced downward the pin 21 of the plate to drive the staple at the same time that the roller 15 falls into the cut-awe ml the head 2 lever to move out of the path. of the driver 22. The staple is then forced through theactingon the roller 55, raises-the plunger" 54 to clench the staple on the underside of I the bucket. As the staple is driven to 'its and cutting anism, of

lowest .point, theplunger 27 advances cutting off the stapled tongue by the punch 29,

piece. Thepail with the tin strip attached is then removed from the machine, and upon the upstroke of the head 13 the'hook 57 en' gaging the ratchet wheel 59 on the feed roller 58 feeds forward the requisite length of wire for the next Staple.
