IMPROVEMENT IN SEED-DRLLS yAND CULTIVATORS.

Specification forming part ci' Letters Patent No. 34,98, dated April S, 18(52.

To all whom, it 17mg/ concern:

Be it known that I, A. B. TRAVIS, of Brandon, in the county ot' Oakland and State of Michigan, have inventeda new and Improved Cultivator and Seed-Drill; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speeitieation, in Which- Figure l is a side sectional vier of my invention, taken in the line x x, Fig. 2; Fig. 2, a plan or top view of the same; Figs. 3 and l, detached views of a tooth pertaining to the same.

Similar letters ot' reference indicate corresponding parts in the several figures.

The object ot' this invent-ion is to obtain a cnltivator and seed-drill the teeth of which may be readily shifted laterally by the attendant in order to coliform to any irregularities in the rows of a crop under cultivation, and also to evade obstructions-such as stones, stumps, &c.\vhieh may lie in the path of the teeth.

The invention has l'urther for its object a simple means for regulating the depth of the penetration of the teeth in the soil.

To enable those skilled in the art to i'ully understand and construct my invention, I will proceed to describe it.

A A represent two Wheels, which are placed loosely on an axle, B, having a dratt-pole, C, attached to its center. On the axle B there is placed longitudinally a bolster, I), which is retained in proper position by the guide-pins c a, said pins projecting down from the bolster, one near each end, and passing loosely through holes in the axle E E are two thumbscrews which pass up through the axle B,'one near each end, and bear against the under side of the bolster. (See Fig. l.)

F is a V-shaped frame, which is formed ot` two oblique bars, b I), connected together at their front ends, and having their back diverging ends framed into a cross-bar, c, which is fully equal in length to the axle B. A crossbar, d, is also attached to the oblique bars b b some distance in front of the bar c, parallel with it, but not so long. (See Fig. 2.) The oblique bars b b of the frame F rest on the bolster D, and the front ends et' said bars are connected by a hinge orjoint, e, to the draftpole C.

To the cross-bar c there are attached a series of inclined standards, f, each having a tooth, g, attached to its lower end. The teeth g may be ot' cast or wrought metal, eachn being provided with a socket, l1., at its upper end to receive the lower ends of the standards f, which are of Wood. The teeth gmay be of any suitable form, and different kinds may be used to suit the character of` the Work to be performed. The form of the teeth used in this particular instance will be fully understood by referring to Figs. 3 and 4t. The two standards f f of the bar c, Which are at each side of the center standard, j", have their upper ends fitted in oblong mortises z' in the bal1 c, and said standards are secured in their mortiscs by keys or wedgesj. (See Fig. 2. These wedges j may be driven into the mortises t at either side ot the standards f, and this consequently admits of a certain degree ot' lateral shifting of said standards. All or any number of the standardsf may be thus attached to the bar c. This adjustment of the standard j enables the attendant toplaee the teeth so that they may Work nearer to or farther from the rows of plants under cultivation. The standardsf do not all have the same degree of inclination, one set, which are secured alternately with the other in the bar c, being more inclined than the intermediate ones. All the standards are braced by rods It from the cross-bar d.

To the under side of the draft-pole C, near its back end, there is attached a metal bar, G, which extends a triiie back of the axle B, and has a slot, made in it to receive the lower end of a lever II, the upper end of which is attached to a rock-shaft. I, placed longitudinally in the frame F, and having handles J attached to it.

XVhen the implement or device is used as a seed-drill, any suitable seed-distributing device is placed on the frame F.

From the above description it will be seen that as the implement is drawn along, the attendant may shit't the frame F, and consequently the teeth g, either to the right or left by operating the rock-shaft I, through the medium ot' the handles .I J, and it Will also be seen that the depth of the penetration of the teeth g into the earth may be regulated as desired by adjusting the thumb-screws E E, thereby raising or lowering the back part of the frame F.

As before stated, however, any forni of teeth may be used.

Having` thus described my invention, what I claim as new, and desire to secure by Letters I Patent, is-
