IMPROVEMENT IN GRAIN-DRILLS.

- Specificationforming part of Letters Patent N0. 196,652, dated October 30,1877; application filed March 12,1877.

To all whom it may concern:

regulated quantities is fed fromthe hopper to the drill-teeth, and its scope will be indicated distinctly in the following specification and claims.

In the annexeddrawings, making part of this specification, Figure 1 is a rear elevation; Fig. 2, a plan and horizontal section; Fig. 3, a vertical transverse .section, and Fig. 4 a perspective view of the bracket which controls the adjustment of the seed-wheel.

The same letters are employed in all the figures in the indication of identical parts.

The grain is carried in a hopper, A, having holes in the bottom, under which are hung seed-cups,made in two parts,B B, curved and converging toward the mouth, in which is placed the wheel 0 and arm D of the bracket D, which slide longitudinally in the mouth.

. The wheel is longitudinallyfluted, and slides in and out through the side of B of the seedcup, passing through the annular plate 0, which is formed to conform to the fluted roller,

and revolves freely in a recess in plate 13,

formed to receive it, thereby supportin g the wheel 0, so that it can rotate and move longitudinally. The other end of the wheel 0 is supported by and slides freely on the tubular bearing B which is formed by the part B of the cup, where it is drawn in around the shaft, as clearly shown in Fig. 2. The wheel 0 is thus supported at both ends independently of the square shaft E, which passes through it.

The end of the fluted feed-wheel runs in contact with theedge of the arm D of bracket D, which slides in a groove out in plate B, and closes so much of the mouth of the seed-cup as is not closed by the fluted wheel 0. The wheel being placed between the arms D D of the bracket D, as the latter is moved one way or the other, it carries with it the feed-wheel. In this manner the quantity of grain supplied is regulated by the position of the fluted feed-wheel in relation to the throat of the seed-cups. This adjustment is effected by means of the sliding bar F, to which the bracket is attached, and which is actuated by the lever G, bolted to it by a roimd bolt, and which, when the feed- Wheel is properly adjusted, may be held in proper position by the thumb-nut G, confining the lever to a segmentally-slotted plate.

To indicate the proper opening for the seedwheel, a plate, H, is attached to bar F, and has a series of points placed opposite a corresponding series of graduated marks on plate I, made to indicate what is a proper opening for diiferent kinds of grain, such as wheat, oats, barley, &c.

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

1. A feed-cup for seed-drills, having on one inner side a tubular journal or bearing, B cast on or rigidly attached thereto, whereon the feed-wheel both rotates and slides axially,

as set forth.

2. In combination, a feed-cup having on one inner side a tubular journal or bearing, B cast on or rigidly attached thereto, and on which a feed-wheel both rotates and slides, and in the other side a ring or disk, through which said wheel passes, as set forth.

3. The combination of the feed-cup, having on one inner side atubular journal or bearing, cast on or rigidly attached thereto, and on which the feed-wheel both rotates and slides, the sliding bar, and brackets, for the purpose of moving said wheel on the line of its axis, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

J. P. FULGHUM.
