UNITED STATES PATENT EEICE,

JOHN N. SLAUGHENHAUP, OF CHAMBERSBURG, PENNSYLVANIA, ASSIGNOR TOQH. S. GILBERT 55 CO., OF SAME PLAGE.

STRAW-CUTTR.

SPECIFICATION forming part ot' Letters Patent No. 273,619, dated March 6, 1883. Application tiled October 21, 1882. (No model.)

To all whom 'it may concern:

Beit known that I, JOHN N. SLAUGHEN- HAUP, a citizen of the United States, residing at Chambersburg, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Feed or Straw Gutters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in strawr or stalk cutters, and has for its object the reducing of straw or stalksto suitable lengths for feeding stock and other purposes. I attain this object by means of the mechanism and construction hereinafter more fully pointed out in the claims and specification.

Figure lis a perspective view of my iniproved stalk-cutter. Fig. 2 is a longitudinal sectional View of the same; and Fig. 3 is a ze detail view, showing the spring-plate and retaining-spring.

Asuitable feed-box, A, is formed and mounted at the outer end upon an uprightrpost or standard, withits opposite end inclined downward. This trough is formed to converge in the form of a spout at the inner end, which is supported upon a cross-bar, a. Beyond this trough, and registering with it, is a deliveryspout attached to the outer frame and inclined 3o downward. Cross-bar a is attached at either end to upright standards B B, between which the spout end of the trough enters. At the f bottom 'of the spout, and on the inside, is secured a metal guard-strip, a', that prevents wearing ofthe wood, and also forms a guard for the knife.

Twoupright standards, B B, are formed with a cross-bar, b, at the bottom and a crossbar, c, about midway of their height, and on 4o the inner face ot' each standard is formed a longitudinal groove extending their entire length. The purpose ot' this groove is to admit the tongue edge of the gate C,which is formed of sufficient width to loosely pass between the standards, and is also formed with a tongue on each edge that loosely fits inside the grooves in the upright standards B B.

Ou its outer face, and near the center of gate O, is secured a pin, d, that is formed to pass 5o through a perforation in the hand-lever D,

| and the outer end of the hand-lever D is pivoted to a short connecting-bar, the opposite end ot' which is pivoted to the outer face of one of the standards B. By means of this hand-lever D the gate O is forced up and down iu the guides between the uprights B B.

VOn the inner face ofthe gate C is diagonallyr secured a knife, e, beveled on its outer edge, and having a straight face on its inner side, so that the gate C in its downward movement 6o causes the inner face of the knife c to pass close to the metal guard-strip a.

Below the trough or feed-box A is pivoted a swinging press plate or gate, E, formed to swing inward and outward, and having secured across its upper end a thin metal strip,

f, the upper edge of which is in line with and presses against the upper edge of the guardpiece a. The inner upper corner of the metal stripf is slightly turned outward to allow the 7o descending knife to pass freely between the stripfand guard-piece a. The object of this metal plate and swinging gate is twofold: first, to clean the knife ot' any substances that may adhere to it; second, to form a rest or 73 lbearing for the outside portions of the material being out, thus preventing' the outer ends of the material from lopping down and crowding the knife, in its descent, away from the edge of the metal strip or guard a.

flo the inside of the swinging gate E, and near the center, is adjustably attached, by means of screw-bolt g, a spring, il, the outer end of which rests against the rear face ot' the standards B B, below the feed-trough. The purpose of this spring-bar It is to hold the metal stripf closely against the knife c in its vertical movement.

The operation of this device is obvious and needs no description. go

Having described my invention, what I desire to secure by Letters Patent is l. In a feed or straw cutter, a trough mounted on standards, as described, the verticallysliding gute having a knife set diagonally across the inner facc of the same, the operating-lever connected to one of said standards and by pivot-pin to the outer face of said sliding gate, and the press-plate pivoted ou a crossrod between said standards and held against icc.

e y 273.619 f the descending knife by anfadjustable crossoutward, said plate being adjustably held bar and screw-rod, each end of said bar-rest'- against the knife e by spring-bar h, substanin g against the rear face of said standards, tially as shown and specified.

substantially as shown and specified. In testimony whereof I affix my si gnature in 5 2. 1n a stalk or straw cutter, the combinapresence of two Witnesses.

tion of the feed-trough A, standards B B, Ver- Y 1 l tically-sliding gate U, carrying diagonal knife JOHN N' SLAUGHENHAUP e, and lever D, pivoted to said gate, with the Witnesses: press-plate E, having a thin metal strip, f, on E. G. ETTER, 1o its upper end, its inner upper corner curved D. K. WUNDERLICH.
