EBEN C. GOMSTOGK, OF SPRINGPORT, MICHIGAN, ASSIGNOR TO HIMSELF AND CHARLES J. COMSTOOK, OF SAME PLACE.

SPRING-TOOTH HARROW.

SPECIFICATION forming part of Letters Patent No. 267,404, dated November 14, 1882.

Application filed June 10, 1882.

To all whom it may concern:

Be it known that I, EBEN O. (JoMsrocK, of Springport, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Spring-Tooth Harrows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in the construction of spring-tooth sulky-harrows; and the invention consists in the peculiar construc; tion, arrangement, and combination of the parts, all as more fully hereinafter set forth.

Figure 1 is a perspective view from the top, with one wheel removed. Fig. 2 is a detail view of one of the clips.

In the accompanying drawings, A represents a suitable frame, provided with stubaxles B at each side, which carry the tractionwheels 0.

E represents longitudinal bars of the frame -A, and to these bars E are pivotally secured the upper arms, a, of the clips F, which are made in two parts, so as to embrace the rods or bars Gr, which carry the teeth H, the lower arms, I), of said clips F beingconnected t0 the bars I, the forward ends of which carry a bar, J, to which the draft is applied in any proper manner.

To the upper end of one of these clips F, on the central bar G, is secured alever, K, which engages with the rack-bar L, rising from the frame, and within easy reach of the driver when seated upon the seat M.

By this construction and arrangement of parts I provide for an adjustment of the points of the teeth by having the bars which carry the teeth fulcrumed to the main frame, which is supported by the traction-wheels, such teeth- (No model.)

carrying bars being connected together by the bars I, as described, and adapted to be operated simultaneously by a lever within easy reach of the driver when seated upon the seat. By carrying the connecting-bars I to the front, as shown, the draft is applied directly to the barrow, thereby avoiding the tendency to a downward draft when it is applied to the frame, which causes an irregular or uneven operation of the teeth upon the ground.

The clip F is made preferably of two parts, a b, Fig. 2, the former extending upward and pivotally connected to the frame, while the latter extends downward and is pivotally connected with the bars I. There are two or three clips so attached to each of the rods G as to embrace the same in line, and with their projecting ends connected, as already described, so that a movement of the lever to the front or rear will rotate all the bars, with their connected teeth, as desired.

\Vhat I claim as my invention is- 1. In a pivoted-tooth-bar barrow, and as a means for hanging the tooth-bars thereof, the clip F, made in two parts, adapted to be clamped on the tooth-bars by drawing the halves together, one-half carrying the arm on which the tooth-bars swing and the other half carrying the arm to connect the tooth-bars with adjust ing-bars, substantially as specified.

2. In a pivoted-tooth-bar harrow, the clip F, formed in two parts, the upper part being pivoted to the frame and the lower part being connected to the adjusting-bars 1, combined with the tooth-bars G, teeth H, lever K, bar J, and frame A E, as and for the purposes set forth.
