MACHINE FOR.BUNDLING SCRAP.

Patented Apr. 23,1912,

To all whom it may concern Be it known that 1, CHARLES W. BEN- of Pittsburgh, Allegheny .county, Pennsylvania, have invented a new and useful Machine for Bundling Scrap, of which the following is a' full, clear, and exact description, reference being had to the acforming part of this specification, in which- Figure 1 is a front elevation of one form Fig. 2 is a section on the'line II-II of Fig. 1; Fig. 3 is a top plan' view; Fig. 4 is a detail section taken on the dine IVIV of Fig. 2 and showin the wire-twisting or tie devices; and.- ig. 5 is ar detail view of a porthis character tion of the gearing.

My invention has relation to machines for bundling metal scrap, and is desi ed to provide a sim le and eiiicient mac ine of by means of which "metal scrap may be rapidly bundled and the bum dles pro erly tied or secured by the operation of t emachine.

' In these drawings, the numeral 2 designates the driving shaft of the machine,

{carrying the driving pulleys 3, and also a spur toothed pinion a, which engages the 1 large spur gearwheel 5 on the parallelshaft 6. The wheel 5 isrotatably mounted on the shaft -6, and is designed to be, connected thereto through the medium of a clutch 7 which is arranged to slide into and out of engagement with a clutch hub 8 of the wheel 85*5. The clutch members are arranged to be levers 16 thrown into clutching engagement by the action of a spring 9, andto be thrown out often agement by means of a shifting rod '10, w ich cooperates with the cam surface 11 "onthe clutch 7. The shifting member v3.0 is connected to the foot lever 12.

13 designates a pocket or receptacle formed at the upperfront portion of the machine, the scrap to be bundled is to be placed. The rear wall of this pocket is formed by the overhung arms is, and its "front wall is formed by the series of fingers 15, which form extensions of the series of; "igidly secured to a rock shaft-17,

"one of said levers being counterweighted at 18, and another of said levers having a downwardly extending arm '19 --pro.lded with an nntitriction roller ramgefi=to engage a cam '21 on the shaft 5.

"20 which is aremployed s- Each I also preferably, although not necessarily,

provide the pocket with onchrmoreguide or guard fingers 22 for the purpose ofrpre venting an undue amount of scrap from being placed in the pocket or receptacle at one time. The arms 14 and the fingers 15 have concave inner surfaces, for the purpose of shaping the scrap into a bundle of approxi matel'y cylindrical form. I

23 designates one of the tie wires, a series of these wires being fed into the machine throu h a series of adjustable tension and straig tening rollers 24 and between the upper and lower feed rollers 25, one of said rollers preferably being adjustably held in position by means of set screws 26. 'The tie wires then pass thr oughlthe rotary twisting headsn27. In the machine; shown in the drawings, three ofithese twisting heads are provided, as shown in Fig. 4, but it will be obvious that any suitable number may be of the twisting heads is driving pinion 28, the pinprovided with a ion of the middle head being driven by a spur gear wheel 29 (see Fig. 2), on a shaft 30. The Shaft SO carries a bevel gear 31,

which is driven by a bevel gear wheel 32 on an oblique shaft 33, whose lower end has a bevel pinion '34, which meshes with a mutilated or segmental bevel gear 35 on the shaft 6 (see Fig. The pinions 28 on the side twisting heads-are driven by the inter mediate idle gears 37, as shown in dotted lines in Fig. l.

36 is a mutilated or segmental spur gear on the shaft 6, which is arranged to drive a pinion 39 on a shaft 40. On the shaft 40 is a driving wheel 41, which is connected by a chain or other belt 42 with the shaft of one of the feed rolls 25.

The tie wires 23 pass obliquely through. the front ends of the twisting heads, and thence downwardly through suitable guides 43 underneath the pocket or receptacle 1.3,as clearly shown in Fig. 2.. On the forward end (it each twisting head is a disk or plate 44 having a peripheral notch 4-5 into which the free end portion of the tie wire is adaptcd to be brought after it has been carried ltlt . arms 14-, thereby compressing the scrap into ferred to.

ing up the slack the feed-1n rollers to cause suiiicient lengths erator removes his'foot from the ,lever or .eiiicient means for tacle 13. This shaft is provided with a spur regular pieces of scrap may be readily comwheel 48, whose teeth are engaged by a toothed rack 49, connected to a bell crank lever 50, having an antifriction roller 51, which is in engagement with the cam 52 on the shaft 53 driven from the shaft 6 by a chain or belt 54, or other suitable means.

55 designates a tension spring connected to one arm of the bell crank 50 for the purpose of holding the antifriction roller 51 in engagement with the cam;

56 designates the cutoff slides, which are mounted to reciprocate vertically in suit-able guides 57 (see Fig. 2), and each of which carries a cutter 58 at its upper end, which is for the purpose of cutting oil the tie wire after each bundle has been tied. Each cutoil slide is provided with an antifriction roller 59, at its lower end, which contacts with a cam 60 on the shaft 53 before re of the fingers 15, and the formed bundles tied mechanically without the necessity for manual operations.

Various changes may be made in the departs. Thus, the arrangement of the driving gear for the several mechanisms may be widely changed; different forms of twisting heads may be employed;

ways, and numerous changes may be made within the scope of the claims.

I claim zpocket or receptacle for the scrap to be bundled, mechanism for compressing or shaping the scrap into bundles, feed devices for feeding the forward end of a coil of tie wire around a formed bundle in said pocket, means for tying the bundle encircling wire into a loop and means for sevgring the formed loop from the coil; substantially as described.

2. In a machine for bundling scrap, a pocket or receptacle for the scrap to be bundled, members for compressing the 61 designates an adjustable idler for tak-" of the belt 42.

The operation is as follows :-The scrap to be bundled is to' be placed in the pocket or receptacle 13; and when a sufiicient quantity to form a bundle has been placed there in, the operator depresses the foot lever or treadle 12; ereby throwing the clutch 7 into driving engagement with the hub of the gear wheel 5. This causes the shaft 6 to commence to rotate and the cam 21 to act upon the antifriction roller 20 to actuate the series of levers 16 to cause their fingers 15 to move rcarwardly or inwardly toward the av compact approximately cylindrical bundle. At this time the cam 52 operates the bell crank lever 50 to actuate the rack' 4-9 and thereby rotate the shafts? an dswing the fingers 4-6 upwardly and overtp ctirry the tie wires 23 around and over the formed buns depositing the free end coil; substantially as described.

pocketor receptacle for-the scrap to be bundled, means for compressing scrap placed in said pocket orreceptacle into a bundle, wire feeding mechanism arranged to pass the forward end of acoil of wire around the formed bundles, means for tying the bundle encircling wires into loops and means for severing said loops from the coil substantially as describe 4. In a machine ,for bundling scrap, a

the disk or plates 45% of the twisting heads. At this time the mutilated bevel gear 35 comes in engagement with the bevel ear wheel 34 and rotates the shaft 33, thereby rotating the series of twisting heads and forming the ties. The cams 60 now operate the slides 56, and thereby the cutters 58;[0 sever the tie wires 23 from the bundle. The toothed segment 38 of the w eel 36 then commences to rotate the pinion 39 to actuate dled, a ser es of levers having fingers extending at the rear of the pocket or receptacle means for actuating said levers, tie Wire feedirgmechanism, a movable finger or arm forcarrying the tie wire around the formed hundle, and twisting devices for the tie wire; substanlly as described.
