IMPROVEMENT IN FEED-cuTTERs.

The schedule referred to in time Lemma Parent and lurking pm f um am To whom 'it 'may concern v Be it known that I, JosEPH SEAMAN, of Chicago,

in the countyof Oook and State of Illinois, have invented a new and useful Improvement in Feed-Outters; and I do declare that the'followiug is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference -marked'thereon and being a part of this specification,

in which- Figure l is a top `pian view of my device; Figure 2,. a side elevationv of the same; Figure 3, a top plan view ofthe feed-rollers;

Figure 4, a vertical cross-section lengthwise-on line rangement of its various parts, as more fully hereinafter set forth.

In the accompanying drawing- A represents a suitable box, to" which is attached at the front end the iron `frame B.

D D are spindies, upon' which are placed the wheels E, whose peripheries terminate in square pointed teeth.

Spindle D is suitably journaled in boxes a, which are'tted into the slots b in the frame B, and so that they will move freely up and down in them.

Over the top and rest-ing oneither of the boxes is placed an elliptic spring, d, which is secured to the cross-bar d;

Attached to this adjustable part extending forward to the mouth of the machine and back .over the feedrollers is a press-plate, K, which keeps the materialto he cut compact. Y

Ou the ends of thespindles D D' are placed the disks F F', whose ou'ter and inner faces, respectively, are provided with equidistant studs ff.

M is a face-plate hinged to the frame B atm, having at its rear a spring, d, which gives sucient outward pressure on the plate-M to insure aperfect shear-cut witll the knives.

f G. is a shaft'journaled inhearings c c o n the side ofi the box andframe, to which is securely placed thev` endless screw H in such' manner that the .studs ofthe disks F F will both gear with it.

On the outer` end`of this shaft G is placed a drivingwheel, I, the one shown having but two arms, to each of whichare secured the knives L.

The knives are so formed and` 'fixed as to pass in front of the face of the machine at an angle approach-- ing forty-tive degrees, and close enough to act asa paix' of shears with the face ofthe machine.

N is acomb secured to the bottom face of thefaceplate, whose teeth project inward to or near the wheels E oul the spindles D', for the purpose oi' cleaning and preventing them from clog lring.

The operation of this class of devices is so well understood that a further description is deemed unnec-V essary.l l

What I claim as my invention, and desire to secure' by Letters Patent, is

The improved construction and arrangement ofthe feedcutter described and shown, consistiugof the box A, the frame B, the spring face-plate, M, the adjustable toothed feed-rollers E E having the crown-wheels F F' driven by the worm-shaft G, the heavy crankwheel I carrying the knivesl L, and the comb N, all substantially as and for the purpose set forth.,-

- JOSEPH SEAMAN. Witnesses:
