IMPROVEMENT lN CORN-PLANTERS.

Specification forming part of Letters Patent No. 157,600, dated December 8, 1874; application filed September 11,1874.

CASE A.

To all whom it may concern:

Be it known that I, ALEXANDER HEARsT,

of Peoria, in the county of Peoria and State of Illinois, have invented new and useful Improvements in Corn-Planters, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a plan view, with the seed-box and the cap which covers the valves removed. Fig. 2 is the same as the last, except that the bar b and one of the valves are removed. Fig. 3 is a plan, showing theplate B in place upon A, the parts above being removed; also the arm d being removed. Fig. 4, a plan of plate A; Fig. 5, a side elevation, a part of the seed-box removed to show the cap F; Fig. 6, a plan of plate 0; Figs. 7, 8, 9, respectively, plan, side, and end views of one of the seed-valves; Fig. 10 a plan, Fig. 11 a bottom view, and Fig. 12 a side view, of bar or lever 12; Fig. 13, plan, Fig. 14 bottom View, and Fig. 15 side view, of arm d; Fig. 16, side view of cap F.

This invention relates to that class of machines in which there is a movable seedslide. In such machines the valves or cut-offs have heretofore been so secured as to allow of no movement except a slight up-and-down movement at one end to prevent cutting the corn, and the corn sometimes clogs and fails to fill the holes in the seed-slide. The chief object of my invention is to obviate this difficulty, which I accomplish by giving the valves a positive forward movement and a return motion with each half-movement of the seed-v slide, regardingaforward and backward movement of the seed-slide as a full movement, thereby agitating the corn constantly, and insuring the filling of the holes in the seed-slide under all ordinary circumstances.

In the drawings, A represents the bottom plate, in which are holes D for the passage of the seed. B is the seed-slide, in which are holes f to receive the seed. 0 is the upper slotted plate or frame, to which the seed-box E is secured. It has legs j, to which the plate A is secured by screws. (1 a are the valves or cut-offs. slide B. Each valve has a lateral projection,

They rest loosely on the seed-' k, upon one side, at the rear end, which moves in a recess, 0, in the edge of the plate 0, and also a downward projection, l, which enters a slot, 9, in the slide B; also a notch, t, in the outer side, and a recess, m, beneath. b is a lever or bar, pivoted upon a bar, 0, between the two valves a (0. Upon its under side are two pins, 11. a, which engage in the notches t in the valves. d d are two arms. Each has a projection, p, at the inner end, on the upper side, and a pin, 1", upon the under side, at the center. These pins pass into holes in the slide B, one of which is shown at. s, Fig. 3. In each side of the part 0 is a slot, h, (see Fig. 6,) which is camshaped at i. The projections p on the arms at d extend up into these slots. These arms d d are of such length and so arranged that when the seed-slide is pushed in the outer end of (I will come in contact with the leg j, (see Fig. 5,) and when the slide is in the position shown d will come in contact with the leg upon the opposite side and at the other end of O; and when these arms so engag'e with the legs the inner ends of the arms will be thrown inward, and 1) will engage with the projection is on the valve. F is a cap over the valves or cut-offs, to keep the corn from their upper sides. It has within it a suitable spring or springs resting upon the valves. This cap and the springs are made in the usual manner.

The operation is as follows: When the parts are in the position represented in Figs. 1 and 5 the projection 12 on d engages with k on the cut-off 0/. Now, if the seed-slide B be pushed in, it will carry with it d, which is pivoted in B, and the valve to will be carried forward by this arm d, which is in contact with It. At the same time the other cut-off, a, will be carried in the opposite direction by means of the bar orlever b, the ends of which engage in the notches in the valves, asbefore described. The distance which the cut-off a will be moved 1s indicated by the dotted line u in Fig. 1'. When it reaches this point, the end of the arm, passing over that point of the side of the slot h indicated by 2', will be disengaged from k,- then, as the movement of the slide continues, the end 2 of the slot 9 will engage with the downward projection l on the cut-off a, and carry it back to the position shown in Fig. 1, and at the same time a will be returned to its former position by the arm I). WVhen in this position last mentionedthat is to say, when the seedslide B has been pushed in, as shown by the dotted line at in Fig. 1the arm at will engage with the projection 70 on a; and" if the seedslide be drawn out and brought to its original position, the operation described will be substantially repeated, at being moved by d, a by b, and the valves being returned by the end of the slots g g coming in contact with the part 1 on a a. This operation will be repeated with every movement of the seed-slide-that is to say, with each half-movement of the seedslide each cut-oft will have both a forward and a backward movement, agitating the corn near the holes f enough to make it certain that they will be filled under all ordinary circumstances.

In other respects the operation is similar to that of similar devices now in use.

The partition or bar 0 performs no office except to furnish a place to pivot b.

What I claim as new is as follows:

The loose cut-ofl's a a, bar 6, and arms d d,

in combination with the seed-slide B and frame or plate (J, all constructed and operating substantially as and for the purposes specified.
