WILLIAM H. ROSSER AND JAMES STIVER,` OF MILL HALL, PENNSYLVANIA.

Leners 'Patent No. 99,352, dated February 1, 1870.

IMPROVEMENT IN FEED-GUTTER.

The Schedule referred to in these Letters Patent and making part of the sme.

.To all whom it may concern Be it known that we, WILLIAM H. Rossnn and J AMES STIVER, of Mill Halhin the county of Clinton, and State of Pennsylvania, have invented a new and useful Improvemeutin Feed-Cutters; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

lThis invention relates to a new and useful improvement in machines for cutting hay and straw, or other articles designed'for feed; and

It consists in the construction and arrangement l hereinafter described, whereby the cutter or knife is caused to operate in a novel manner, and more etticiently than in other machines of this class.

In the accompanying drawings- Figure 1 represents a front view ofthe cutter-lever, knife, and the cutter-box. y

Figure 2 is a cross-section of iig. l, through theline :c x.

Similar letters of reference indicate corresponding parts.

A is the face of the cutter-box, against the light projecting flange of which, B, the knife works.

The face is made of cast-iron, with one-end, A', extended, so as to support the fulcrum C, of the cutterlever.

This fulcrum is a pin, which may be either east in the plate, or secured therein in any suitable manner.

D is the lever, to which the cutting-edge E is attached, by screws or bolts, so that it may be detached,

for grinding.

Ilhe body of the fnlcrum-pin is square-in its crosssection.

f is a plate, which is placed on this square part of the pin. It has a round collar, g, over which the lever D ts, and on which is works.

Between the plate f and the face-extension, a number of springs, h, are placed, the tendency of which is to press the plate outward.

i. is a thumb-nut, on the 'end of the fulcrnm-pin C.

j is a. washer, under the nut and over the plate f.

lrepresents inclines, formed on the face of the extension Aand upon which the inner face of the outer end or extension d of the level D works.

` These inclines are so arranged, that immediately after the edge E begins its cut, the end d of the lever comes in contact with them at the base,- and, conse# quently, the edge is caused (when completingits stroke) to press, by aid of springs h, more iirmly upon the lower rim orv ange of the plate A than at any other point in its movement. rIhus we completely obviate one of the-.most objectionable features in the operau tion of ordinary feed-cutters,viz, the tendency of the cutter to crowd off from the face of the cutter-box, so as to leave the lower portion of the straw-ends uncut.

K represents a curve, iu the inner end of the out# ting-edge E, and

L is a curve in the lower portion of the face A and flange B.

By the action of the lever, the hay or'straw, which is being cut, is forced between these curves before the out terminates, which completes .the cut with less exertion of force than would be required if the feed were forced into anzangle, as the curves serve to spread the straw-or hay over a broader space.

Havn g thus described our invention,

WeV claim as new, and desire to secure in Letters Patent- V l. The combination of inclines l,with.a cutter, c, when arranged substantially as and for the purpose set forth.

2. The combination of the inclines l, springs h, pivotpin G, washer f, with the extension A' and lever D,

all constructed and arranged as shown and described. The above specification of our invention signed by us, this 9th day of November, 1869.

WM. H. ROSSER,

JAMES STIVER. Witnesses JN0. O. Rossnn, FRANCIS PLATT.
