To aZZ whom it may concern:

Be it known that 1, JOHN LAUGHLIN,-a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Hay, Straw, or Fodder Cutters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the 1:) art to which it appertains to make and use the same. 7

My invention relates to hand operated hay, straw, and fodder cutters, especially that type shown in Letters Patent Nos. 7 6,209 and 180,042, heretofore granted to me, wherein two knives having, respectively, a cutting edge of approximately V shape, may pass one another in their up and down reciprocations, and. by their reversely (slightly) convex form, and the action of a lever pressure bar having a fric-' tion roller on its bearing end, sharpen themselves while cutting the straw, feed or fodder with a shear-cut; and the object of my present improvements is to provide a simple 2 5 and convenient means for supporting and adjusting on the discharge end of the machine,

a gage stop-bar, so that the length of cut may be varied from, say, one quarter to four inches, or more or less, as desired.

In the accompanying drawings, Figure l is a top view of my improved feed-cutter; Fig.

2, a vertical central section of the same as it appears when fully equipped and in use.

Fig. 3 is a perspective view of two portions of 5 the cutting-box, the portions being shown separated but in relative positions for being united. Fig. 4. is a perspective view of the toothed and handled hand feed-block. Fig.

5 is a view of the forward end of the feedcutter. Fig. 6 is a perspective view of the sliding frame to which the upper cutter and gage stop-bar are attached. Fig. 7 is a detail broken view of a portion of the gage stop bar and one of the brackets and fastening- 5 pins, and Fig. 8 is a diagram showing the convex shape of the knives.

In the drawings, A represents a frame for afeed cutter, and this frame, preferably, comprises a single rear standard B, two inclined,

5o forwardly extending braces C, 0, having at tachment to the foot portion of standard B;

is necessary in. cutting a short counter brace D, crossing the upper part of the braces O, C; a vertical front end board E, a horizontal brace E, and two upright grooved front standards F, F, connected at the bottom by a cross piece, forming an arched base or sill G,as represented. The braces C, C, abut with their mitered ends against the front end board E, and also against the under side of the stationary portion 0 the cutting box H, and are fastened at a, to the horizontal brace E; and at a, to the center of the counter brace D; while the counter brace abuts'against both the bottom of the fixed portion H, of a cutting box and the top of the brace E being seen red by screws, or otherwise, as illustrated. The brace E, is dovetailed to the front end board and secured by screws. I

The part H, of the cutting box H, is fastened in any suitable manner to the framejust described. On the under side of the front end of the part H, of the cutting box, an arched block I, is screwed, this block being so constructed, that a'wide groove 1), is formed between it and the bottom of the part H, of the cutting box, to receive a tongue J, formed on an extension portable portion H ofthe cutting box, said tongue being screwed to the under side of the-portion H and adapted to snugly and exactly fit into the groove in the arched block I, as is plainly illustrated in Figs. 1, 2, and 3 of the drawings. Sometimesit is necessary, as in packing for transportation, to take this extension off,and at other times it feed, as corn stalks, straw and the like to add to the length of the. cutting box. These requirements are met in a very perfect wayby constructing the cutting box in two sections H, H ,.as herein shown and described. dotted lines at so, that the frame is adapted for receiving the extension H when it is removed from the part 1-1, of the cutting box-and thus the extension can be moved away to a convenient position and kept safely when not in use, also the machine can bemade more compact for transportation. The part .11 of the cutter box H can be put entirely out of the way when not in use, and while being transported. The hand feed block K, is

formed of a flat board 0, of a length nearly In Fig. 3, l have shown by the width of the trough and at rightangles to the length of the block. An arched or loophandle is provided on top, while in the bottom of the board, rake teeth 0 of metal, or wood, are inserted. By taking hold of this handle with down into thehay, straw or fodder, and by giving it short s'uccessive forward pushes, the material will be forced forward. This hand feed block affords a support to the operator, and thus saves him much strain of his back, a' result not secured when the substances are fed forward by a rake with a simple upright handle is employed, the control with the hand is not as perfect, and turning and bending of the hand and body are necessary to a fargreater extent than with my block havinga horizontal looped or arched handle.

The cutting mechanism of my machine comprises two reversely reciprocating frames L, L, V edged knives M, M, carried by said frame, and levers N, N, connecting devices N N also a lever pressure device N*, with roller (1; all so connected,that the knives are reciprocated vertically in opposite directions. The frames move up and down in grooves of the standards F, F, one frame moving pastthe other, and both moving in the one pair of grooves.

The knives are made of sheet steel, with edges that are, approximately, in the form of a V; and the blades are slightly convex on their opposite faces, see Fig. 8, so that as they pass each other they shall be self sharpening, and produce a double shear cut. A close fit between the knives as they descend, or in the cutting operation, is insured by the pressure bar N having the friction roller 61, at its free i longest required feed can be cut-the adjustment being ferent lengths of feed required. The canvas or cotton cloth t is fastened j and by its upper edge to 1 of the upper knife frame L. This apron diend. The hand lever N, is pivoted near the middle of its length to the top bar or rail of the frame L, and is also connected to the upper end of bar N, which bar is connected some distance above the roller d, to a bolt cl, passed through one of the grooved standards, outside the-vertical outer edges of the frames L, L, confining it to said standard. The bar N, serves to keep the lever N, in position, and for properly forcing it toward the grooved standards, and therebycausing said lever to move frame L, in close relation to the moving frame L, and thus insure a perfect cut with the two knives, while at the same time room is afforded for the convex blades to pass each other with a contact which insures self-sharpening and a shear-cut. The. lever N, has a long free handle end, and when it is raised, the frame L, moves with it, while at the same time, through the connecting parts N N it causes the, lever N, to descend and carry downward the frame L, thus causing the two frames to separate the knives. fed between the knives while they are apart, the lever N, is forced downward by the opera- (5 tor pressing it downward carrying with it the one hand, the teeth can be forced I the hand directly, while, where Straw being discharge end of at each end. Each 5 answering to rack teeth, are formed, and on 1 the bars the lugs slipped. By lugs, and in line with any two opposite notches iof the two notched bars, the gage bar can be 5 held at the required distance from the knives.

and have its eyed lugs f,

5 moving frame,

frame L, and causing the frame L, through the connecting devices N N and lever N, to rise, thus bringing the edges of the knives together. so that they will pass each other with a shear-cut and sever the feed.

No specific claim is set up herein for the knives, moving frames and pressure bar with friction roller; nor the bracing, as these parts Q are substantially the same as in my patents hereinbefore mentioned.

P, is a broad, gage stop-bar applied at the the machine. This bar is,

wood, and provided with secured to its outer face of these brackets P, is f, having a circular horiit, and a vertical pin hole preferably, made of metal brackets P,

formed with a lug zontal eye through 1 g, for the insertion through it ofa pin g, hung by a strap to the upper moving frame. The

bar P, is supported on the frame L, by means of two round, notched arms P which are provided with brackets cured to the moving h, by which they are seframe L.

On the inner sides of the bars, notches h,
