CLOVER-SEE D STRIPPER.

SPECIFICATION forming part of `Letters :Patent No. 278,286, dated May 22, 1883.

Application filed anuary 18, 18533. (No model.)

To all whom it may concern Be it known that I, HENRY H. SPEARS, of Paris, in the State of Kentucky, have invented a new and useful Improvement in Clover-Seed. Strippers, which improvement is fully set forth in the following specication and accompanying drawings, in which- Figurel is a side view of myimproved cloverseed stripper. Fig. 2 is a perspective view of a portion of the forward end ot' the body carrying the stripping-teeth 5 and Fig. 3 is aside view, partlyin section, of the tooth-bar and tooth.

'The object of my invention is, first, to provide a simple and efficient means for raising or lowering and inclining the bed or body of a clover-harvester or seed-stripper 5 and, second, an improved form `of tooth-bar and shank forsecurin g the tooth thereto. 4

In the accompanying drawings, A represents the frame, `made in any suitable manner and mounted on wheels B. l

The body Gis designed to have on its forward end the teeth for stripping or heading clover, as shown more fully in Fig. 2 The body C is suspended beneath the axle by means of two arms or lev`ers,`l). Each lever is provided with a slot, F, through which the axle passes, and the upper end isprovided with a rack-bar, E, which engages with a pinion, H, on the cross-shaft J. The lower end of the arm or lever D, is hinged to the body C, as shown at G,

`H represents the pinion or wheel rigidly secured to the cross-shaft J.

I is a lever, hinged to the cross-shaft J and provided on its side with apawl, (not sliown,) which engages with notches in the side of the arch I. Attached to this lever I is a rod, M, whose opposite end is connected with the bellcrank lever N. The opposite limb of the bellcrank lever has a rod, O, attached thereto, and the lower end of this rod is in-turn secured to the forward end of the body C. By drawing back thelever I the forward end of the body is raised, and `by throwing `the lever forward the front end of the body is lowered.

Centrally on the shaft J is a ratchet-wheel, K, rigidly secured thereto. A pawl, K', hinged to the frame on the rear side ot' the ratchetwheel, `acts thereon, so that when the shaft containing the pinion or wheel H is turned so as to elevate the body C the pawl holds it in the desired position. The wheel K, containing the pawl, is provided with oppositely-disposed sockets to receive the endof the lever L, as shown. It will be observed that the arm D is hinged to the bodyT U, and since the siot F keeps the arm to the axle, and the upper end plays into the pinion H, a guard, H', is placed on the forward side of the rack-bar E,

so as to keep the bar E and arm D verticalat l all times.

P represents the tooth-bar, formed of two parts, parallel with each other, and placed a sufficient distance apart, one above the other,

to permit the shanks of the teeth to pass between. This bar may be made stationary to the body G, or constructed so that it may be partially revolved or raised and lowered, as described in a former patent issued to me.

The teeth Q are long and tapering, with the A upper side dat, as shown. -The sides are inclined, forming a triangular shape in crosssection ata point forward of the heelv R, so that the forward end ot' the hook is pointed.` The hilt S is screw-threaded and projects through between the bars P, and is provided with a nut, T, so that the tooth may be iirmly secured uto the bars. rI he heel Ris squarein cross-section to prevent the tooth from turning.

The operation will be Ireadily understood from the description and drawings. The forward end of the body C is suspended by the rod O and operated by the lever I. The rear end ofthe body hangs on the arms lD and `is adjusted by the lever L and the ratchetwheel H and rack-bar E. The teeth may be4 readily removed and replaced, and when secured in position are not liable to be disarranged or lost. l

What I claim as new is f 1. The arm D, slotted for the wheel-axle to pass through, and having rack E ,the body U.

pivoted to said arm 1 the pinion H, shaft J, 95

leverI, having a side pawl, the arch I', rods M and O, and bell-crank N, all combined and operating as described, whereby said body may be raised or lowered bodily as woll as tilted, substantially as described.

2. The two parallel bars'P P, as shown, in combination with the teeth Q, at on the upper side and triangular in cross-section, havs ing the square heel R and taperingpoint, and

5 the hilt S, and nut T, substantially as herein set forth.

In testimony that I claim the yforegoing I HENRY H. SPEARS.
