FRANK HAMA CHEK, OF KEWVAUNEE, WISCONSIN.

FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 349,713, dated September 28, 1886.

Application filedDecember 2B, 1885. Serial No. 186,870. (No model.)

To all whom it may concern:

Be it known that I, FRANK HAMACHEK, of Kewaunee, in the county of Kewaunee and State of Wisconsin, have invented new and useful Improvements in Feed-Gutters; and I do hereby declare the following to be'afull, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention, to be hereinafter distinctly claimed, relates to feed-cutters, and especially to improvements in the feed-cutter for which Letters Patent No. 308,609 were granted to me a December 2, 1884. Heretofore greattrouble has been experienced by straw and foreign 'matters getting in between the end of the feed-rolls and the sides of the throat of the feed-cutter and clogging the rolls and otherwise obstructing the operation of the machine.

The object of my invention is to provide a device whereby the straw or material fed to the machine shall be kept away from the ends of the feed-rolls, and whereby any foreign matter that accidentally gets in between the ends of the feed-rolls and the sides of the throat may be readily removed.

In the accompanying drawings, Figure 1 is an elevation of the inside of the feed-cutter at and near its throat. Fig. 2 is an outside elevat-ion of the plate and adjustable bar shown in Fig. 1. Fig. 3 is a horizontal cross-section on line a': a; of Fig. 1. Fig. 4 is a vertical section of the adjustable bar. Fig. 5 is a top view of that part of the feed-cutter embodying my invention. Fig. 6 is a front view of the throat of the cutter, the ends of the feed-rolls being broken away, showing interior parts more plainly.

The same letters refer to like parts in all the views.

The plate a, the outside of which is shown in Fig. 2, is made of cast-iron, and forms the side of the box of the cutter at its throat. This plate a is affixed to the supporting-frame and side of the cutter by screws or bolts passing through the apertures b b into the frame 0 of the cutter. The lower feed roll is j ournaled at each end in the plate a at d on each side of the cutter-box. On the outside of the plate a there is a projecting guide, 6, and a bar, f, provided with a slot, g,'which moves vertically on the outside of the plate a, the slot 9 being adapted to receive the projection e, whereby the barf is guided.

In the plate to, directly over the journalaperture (1, is a vertical slot, h, which vertical slot is adapted to receive a guide, t, which projects from the bar f. The bar f is also provided with an aperture, j, in which the upper feed-roll is journaled. The slot 9 in the bar f extends upwardly so near to the aperture j and the slot h in plate a extends downwardly so far toward the aperture d that when the feed-rolls are near together a small opening, is, is left through the side of the cutter opposite the ends of the feed-rolls, and as the rolls are separated by material fed between them this aperture is correspondingly enlarged.

At the throat of the cutter, between the bottom Z and the top guard-board, m, and just in front of the feed-rolls, I provide on the inner face of the plate a a wedge-shaped projection, at, increasing inthickness toward the front 0. The front edge, 0, of this projection I preferably form in two curves or segments of a circle, to adapt it to the form of the feed-rolls.

the feed-rolls force the straw as it is fed to the rolls away from the sides of the throat of the cutter, so that the straw will not get in between the ends of the rolls and the side of the box, and so that the straw will not be forced against the sides of the throat as the straw passes between the feed rolls under their pressure.

It will be seen that any foreign matter that accidentally gets in between the ends of the feed-rolls and the sides of the cutter may be readily removed through the apertures k.

What I claim as new, and desire to secure by Letters Patent, i

1. In a feed-cutter, the side throat --plates, a a, provided with the thereon-cast rigid inwardlyinclined guide projections in front of the feedrolls, which inclined projections extend inwardly beyond the outer ends of the feed-rolls, 'whereby the material being fed to the cutter These wedge-shaped projections in front of is kept entirely between the rolls and away from the sides ofthe throat of the cutter after it has passed the projections, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
