STRAW-CUTTER.

FBPECIPICATION forming part of Letters Patent No. 342,19 9, dated May 18, 1886.

Application filed March 8, 1886.

To all whom it may concern.-

Be it known that I, GEORGE SUTTEN GARTH, acitizen of the United States of America, residing at Mill Hall, in the county of Clinton, in

.the State of Pennsylvania, have invented a new and useful Straw-Cutter, of which the following is a specification.

This invention has relation to improvements in straw-cutters of that kind provided with a throat-piece or frame, and having a pivoted knife; and the objects are, first, to provide a machine of the kind named, and for the pur' pose of cutting straw and similar substances, which may be readily and conveniently taken apart and packed for shipment; and, second, to improve existing constructions by simplifying their mechanism and increasing their durability and utility. With these objects in view my invention consists in the novel construction and combination of parts, as will be hereinafter fully described, and as will be specifically and clearly pointed out in the claims.

My improvements are fully illustrated in the accompanying drawings, forming a part of this specification, wherein- Figure 1 is a perspective view of the machine ready for operation. Fig. 2 is a front elevation of the throat-piece or frame,with the fulcrum-plate with one of the adj ustable bearing-plates removed and shown in detail. Fig. 3 is avertical sectional view of the throatpiece or frame. Fig. is a rear view of the fulcrum-plate. Fig. 5 is a view of one of the front legs. Fig. 6 is a rear view of the knifelever and fulcrum-head. Fig. 7 is a view of the gage-plate. Fig. 8 is a perspective view of the rake, and Fig. 9 is a longitudinal central sectional view, taken through the fulcrum and lever-heads on the lines a m of Figs. 2 and 6.

In the drawings like parts are identified by similar notations.

Reference being had to the drawings, the letter A designates the feed-cutter box,which may be made of any desirable dimensions, and consists of a bottom piece having side pieces secured thereto, and arranged generally to converge in the direction of the throat of the Serial No.194A23. (No model.)

machine, and over the forward end of the box is fastened athroat-cover, 1, which is arranged at an incline depending toward the knife end ofthe box. The box at the rear is supported by a single standard, 2, having itsaupper end mortised in a cross head, which is secured to the bottom of the box by screw-bolts. The front legs, 4 and 5, are plain supports having their upper inner faces chamfered to set the feet out and brace the set of the box.

The letter B designates the throat-piece or frame. This consists of a metal casting, or of steel struck into proper shape to set about the end of the box.

More specifically describing the throat-piece, it consists of a metal frame-plate to set over the ends of the bottom and sides of the box, and is formed with a flange, 6, extended back from the inner face at right angles to the face along the bottom of the frame and up the sides thereof, and the edge of the frame next to the handle has an edge flange, and both sides have cap-pieces 7, to set over the upper ends of the legs to form seats for supporting the frame and knife mechanism. In the side flanges and in the bottom flange are formed open-ended slots 8 9. The side flanges fit snugly against the outer faces of the side pieces of the box,and the bottom piece sets under the bottom board, the open-ended slots of the side flanges taking in the bolts 10, proj ected through the sides of the box, and the slotv in the bottom of the frame slipping straddle of the bolt 11, projected through the bottom of the box. The slots being somewhat fiared,the throatpiece is drawn up snug and tight against the box and held firmly, in all its connections, in position. Cast as a part of the throatpiece is the fulcrum-plate 12, having a circular bearing-surface formed with seats 18 14, to receive adjustable bearing plates, and also having an annular ridge or plate, 15, on its face, to set within an annular groove or seat in the fulcrum-head 26, hereinafter described. In the center of the seats 13 and 14 are formed nutseats 16, having bolt holes through which setscrews 17 are passed, and in the seats 13 and 14 are arranged bearingplates 18. These bearing-plates are preferably segments of a circle, and their purpose is to afford means for readily correctly and securely adjusting the range of the knife-lever in its relation to the faceplate of the throat-piece. About the face of the throat-piece is a ridge or flange, a, which is inclined slightly from the top of the side pieces to the bot-tom, substantially as shown in Fig. 3 of the drawings, the purpose beingto give the knife a better cutting-bearing in its sweep, this because the tendency of the cut is to throw the knife out from the face of the throat-piece and give an uncertain or yielding cut to the bundle of straw, which uncertainty increases in the downward progress of the knife, leaving the ends projecting ragged and sometimes uncut; but by making the face inclined, as stated, this difficulty is largely remedied or wholly overcome and the cut is made clean and thorough. The outer end of the fulcrum-plate is extended somewhat beyond the edge of the fulcrum-head of the knifelever, and is formed with a nut seat and bolthole, 19, through the latter of which is arranged an adjusting-screw, d, the end of which takes the notch of the arm of the retainingwasher and keeps the nut of the bearing'bolt from turning olf. I thus provide an adjustable washer to take up wear, and which may be set at any adjustment to suit -the union of the parts at this point. In the center of the fulcrum-plate is a bo1t-hole through which is projected the bearing-bolt 20, which has its square or angular head sunk in a seat in the outer face of the fulcrum-plate, and is thus kept from turning. As heretofore stated, the throatpiece fits snugly about the end of the cutter-box on the bolts named, which bolts 10 are projected through the front legs and have applied to their projecting ends threadednuts, whereby the box, the throat-piece, and the legs are held firmly and securely together, and each in its proper place and relation.

The letter O designates the cutting-knife lever, having a handle, 22, extended therefrom, and formed with an evener, 23, extended above the knife 24, which last consists of a curved piece of steel having its seat in the face of the lever, substantially as shown. The knifeseat in the lever is provided with elongated holes 25, arranged with their length in the direction of the length of the lever, and through which the knife-bolts are passed. These elongated bolt-holes permit a knife to be applied which has its bolts set at different distances from one removed. Cast to the lever, as a part thereof, is the fulcrum-head 26, consisting of a plate having formed therein an annular groove or pit, 27, to fit over the ridge or plate of the fulcrum-plate. The connection of these ele ments gives a bearing to the parts in combination, and causes the lever-head to move on a true are without putting all the strain on the bearing-bolt holding them together, the bolt, as stated, not moving or turning. In the center of the groove or seat 27 is a bolthole, 28, through which the bolt passes, and a nut applied on the end secures the parts together, as will be stated. Awasher, 29, sets over the projecting end of the bolt 20, and is formed with an arm, 30, terminating in an inward-projecting lug, 31, formed with a notch to set over and on the end of the adjusting screw 19 in the fulcrum-plate, the purpose being to prevent the nut on the fastening-bolt from being loosened by the movements of the level-head.

I am aware that a washer with an arm is shown in my former patent, No. 109,197, dated November 15, 1870, wherein a plate is interposed between the lever-head and the washer, and the arm of the washer stayed on a lug on the lever-head; but such a construction is not applicable to the present machine, since the washer would turn with the lever-head and eventually turn off the nut on the fastening bolt; and my improvements in this relation consist in the adjusting-screw through the fulcrum-plate and staying the end of the washerarm on that element, which permits the leverhead to move independently of the washer, and thus the arm is set in one position and the fasteningnut notjeopardized. The adjust ing-screw also provides means for adjusting the arm of the washer to its proper bearing in any changes of the parts, whether resulting from designed adjustment or by reason of wear. On the outer face of the lever-head is formed a gage lug or post, 32, and on this is arranged the eye 33 of the gage D. This gage is a metal plate having an eye at the end to slip over the gage-post, said eye being provided with a setserew, 34, by which the gage is secured to the 1 On the front leg, nearest the handside ofthe box, I fix ablock, 35, made to incline outward from its top toward the bottom, and in this block is fixed a hook, 36, to stop the downward movement of the knife. The object of this construction is to prevent the lever from being broken ifstruek by a passing object moving in the direction of the mouth of the box, and guarding against the same dangerifstruck by an object going in the opposite direction.

This is attained because the block givesa rest to the handle in theone direction and thehook in the other, thus shortening the purchase on the fastening-bolt,or giving no purchase at all.

The letter E designates the rake. This is comprised of the rake-head 37, provided with projecting teeth 38, and formed with end projections, 39, which set over and on the edges of the side boards of the cutter-box and prevent the teeth from striking the bottom ofthe box. To the rake-head is secured a handle, 40, extended at right angles to the head, and has fixed to its other end a cross head, 41, formed with notches in its lower edge, this cross-head serving as a presser-bar to set on the straw.

The machine is readily set up or taken down. To set it up the hindleg is secured in place. The bolts of the front end are then put in their places. The th roat-piece or frame may then be slipped in position and the lower or bottom bolt be screwed up. The front legs are then put on the boltsand the nutsapplied and screwed up. The knife mechanism,if detached from the throat-piece,may be then set and secured in place and the knife and lever adjusted by the adj ustingscrews and bearing-plates in the fulcrum-plate, when the machine is ready for operation.

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

l. The combination, with the cutter-box and the front legs thereof, of the throat-piece or frame having flanges set at right angles to the face part and formed with open ended slots, andfastening-bolts projected through the sides of the box, the open-ended slots and the front legs, substantially as described.
