FEED-CUTTER.--

SPECIFICATION forming part of Letters Patent No. 301,975, dated July'15, 1884.

Application filed July 23, 1883. (No m odelJ I To all whom, it may concern.-

Be it known that I, PETER FISHER, of Oak- My invention relates to feed-cutters, and

will be fully described hereinafter.

In the drawings, Figure 1 is an elevation of one side of my improved feed-cutter; Fig. 2, an elevation of the other side; Fig. 3, a vertical longitudinal section of my device, and Fig. 4 a detail. Fig. 5 is a plan view of my device. Fig. 6 is a-plan'v'iew of the drivingshaft connections.

A is the stand or frame of my machine, and B is the'box thereof, in which are curved slotsa a.

O is a frame, one end of which swings upon a shaft, 1), that extends through the slots a a and carries pulleys b. I

c is a pulley, the trunnions of which rest in bifurcations in the ends of the side bars of frame O, opposite those through which shaft 1) passes; andc is an idler that is journaled between pulleys b and c. The pulleys Z) are notched on their peripheries, and I pass a belt, D, over them and pulley c, which belt thejidler 0 serves to tighten, as shown in Fig. 3. The shaft 1) is provided on one of its ends with a sprocket-wheel, B, and from each end of this shaft I suspend rods d to receive a beam, d, on which the free end of a spring, E, rests while the opposite end of this spring 'is firmly secured to the frame beneath the box B, as shown in Fig. 8.

F is a bracket, in which and the side of the box 13 a stud, F, is journaled, and this stud carries a sprocket-wheel, f, and cogwheel f,- and F is a bar'through which the stud F and shaft 1) pass, which bar braces them apart against the tendency of a belt, G,

to draw them together.

H H are toothed rollers, which are journaled in the frame A and project up through the bottom of the box, beneath the belt D, and the journal h of roller H carries a sprocketwheel, f and cog-wheelf", while the sprocketwheel f is connected by a belt, 11, with another sprocket-wheel, f, on shaft h, as shown in Fig. 1 of the drawings. The journal of shaft II, on its end opposite that which carries sprocketf is'provided with a sliding cog-wheel, K. having a grooved hub, K, and a bell-crank lever, K having fingers on one end, is pivoted to the frame in such a position that the fingers will rest in the groove in hub K and its other end will project out at right angles to the frame, to take into a slot in lever L, which latter is pivoted to the frame at Z and extends up to the top of the box, where it is provided with a pawl, Z, that engages with a notched bar, Z

M is'a bracket, the base of which is firmly secured to one of the' corner uprights of the frame A, and from this bracket a stud, m, projects in toward the box, and this stud forms the axle of a bell-crank lever, M, and pinions m m One end of lever M projects up above the side of the box B, and is provided with a catch for engagement with anotched plate, at, while its other end carries a stud, n, that forms the axis of two cog-wheels, N N.- The main driving-shaft O, which is journaled in inclined bearings 0 0, carries the knife-wheel I? on its highest end, and is squared on its lower end, and carries bevel-pinions P and P which engage with the teeth of the bev el-wheel q,- and the shaft p, which carries the bevelwheel g, has keyed onto it the cogged pinion g, which meshes with pinion m, causing it to revolve pinion m, the teeth of which mesh with those of cog-wheel N, revolving it and its companion N. The cogs of pinion q are shaped as shown in'Fig. 6, so thatwhatever position the shaft 1) may be moved to they will be adapted to work against those of pinion 011/ without the least jarring.

The cog-wheels Nand K are .shown in engagement in Fig. 2 of the drawings, when the parts are in position for the maximum feed; but should a slower feed be required the cogwheel K may be moved in by the bell-crank lever K and upright lever L until it clears cog-wheel N and passes under pinion N. Then lever M may be released from plate m and end has its bearing in an upright lever, B, on

the opposite side of the box, the lower end of lever B resting in the lug R while its upper end is locked in its adjustment in any convenient manner. hen lever B is in the position shown in full lines, Fig. 1, the face of gear-wheel q will be exactly parallel with shaft 0, and there will be no contact between it and the bevelpinions; but if the lever bemoved into either of the positions shown in dotted lines, then the shaft 1) will be canted so as to throw the teeth of wheel q into gear with either pinion I or I according as it is desired to feed to or from the knife-wheel. The pulley c and idler c are both heavily weighted, either .by being made of iron or of some lighter material in which lead or some other heavy material is embedded, and therefore they will press upon the stock and pack it through the belt I) as it is carried to the knife-wheel by said belt and the rollers H H; and to guide it to the knil'cafter it leaves the roller 1], I provide another rol ler, H, and a shield, II, the ends of which slide in grooves I in the sides of the box. In order that shaft I) may carry the belt D evenly, I provide it with several pulleys b; but instead of several I may make one long pulley do the work.

\Vhat Iclaim as new, and desire to secure by Letters Patent, is

1. In a feed-cutter, the combination of the swinging frame 0 and the belt-carriers 0 c with the feed-rollers H and H, and the transverse shaft b, carrying the notched pulleys b b, substantially as shown and described, and for the purpose set forth.

2. The con1bi11ation,with thcshaftb,carrying notched pulleys I), of the box having curved slots a, the chain 1), idlers 0, pulley 0, feedrollers H II, and spring E, as set forth.

3. The shaft 1), having one bearing in rocking bar R and the other in a lever, B, in combination with the bevel-wheel q and drivingshaft carrying the bevel-pinions, and with gearing for coimnunicating the motion of the driving-shaft to the moving parts of the machine, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, on this 11th (lay of May, 1883, in the presence of two witnesses.

PETER FISHER.
