UNITED STATES MARSHALL GREGG, OF CALIFORNIA, MISSOURI, ASSIGNOR OF ONE-HALF PATENT EEIcE.7

HIS RIGHT TO WILLIAM A. LYONS, OF OHAMOIS, MISSOURI.

IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 158,487, dated January 5, 1875; application filed September 8, 1874.

To all whom t may concern Be it known that I, MAEsEALL GREGG, of California, in the county of Moniteau and State of Missouri, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification:

My improvement relates to the construction The seedboxes are traversed by the axle-shaft, so that the rotation of the shaft acts to prevent the corn Y from lodging in the seed-boxes. seed-slides are worked by a rotating camwheel on the axle, associated with springs, the cam-wheel forcing the slides outward, and the springs drawing them inward. To stop the movement of the seed-slides the springs are pressed outward by the arms of a lever, which holds the slides out of contact with the cams.

In the drawings, Figure lis a bottom view. Fig. 2 is a section at x, showing the parts beyond the section-linein elevation. Fig. 3 is a section through the end ot' a seed-slide and part of seed-box bottom.

A A are the ground-wheels, which are both fast to the axle-shaft B, (so that the said shaft O O, Sto., are markers, so placed upon the rim of the wheel that they make impressions in the ground at points in line with the spots where the corn is dropped. D D are seed-slides, whose inner ends are in Contact with the inclined teeth or cams e of the cam-wheel E, which is fast upon the axle-shaft at its mid-length. As the camwheel turns, it forces out the seed-slides D D simultaneously, and as the salient parts of the cams e pass the ends of the slides, the latter are drawn inward by the springs FF. The fixed ends of the springs are attached to thefront cross-bar, G, ofthe frame. The frame has longitudinal bars J K L, resting on the axle-shaft, and, in addition to the bar G, has other transverse bars, H and I. M M are the seed-boxes. The axleshat't passes through the seed-boxes M M, so that the rotation otl the shaft prevents the corn from becoming jammed in the box when dropping is going on. The seed-boxes have a bottom, N, and a false bottom, O, havin g', respectively, seed openings or holes a and 0. The arrangement The is such that when the seed-slides are in their inward position the seed-holes d therein are in connection with the holes a in the bottom, and when the seed-slides are in their outward position the holes d are in connection with those o, so that the said holes d become charged with seed, which is dropped on the next inward movement of the slides, when the holes d come in connection with the holes n. Between the springs FF is a two-armed lever or spreader, P, whose ends p are arranged so that as the lever is turned into a transverse position, the said ends are brought in contact with the inner sides of the springs and force them asunder,sothat the seed-slides are held outward, clear of thecam-wheel E, and consequently the dropping of corn ceases. The leverl? is fulorumed on a shaft, Q, having an arm, q, against which the foot of the driver is pressed, to bring the leverl? into its operative position, (so as to hold the seed-slides at rest.) R R are the plows by which the furrows are opened to receive the seed. These plows are attached to curved beams S S, each ot' which is secured at the front end to a draw-bar, T, and a curved spring, U, the arrangement ot' the spring being suoli as to tend to hold the plow in the ground, but yet to allow it to rise over any immovable obstacle, bythe action ot' the jumping colter V. The covering-plows W W have beams Y Y, similar to those S S, and are pivoted at their fore ends to the beams S S, so as to allow the plows an independent vertical movement. The plows W W are provided with jumping colters V V, in a similar manner to the plows R R, and for a similar purpose. The rear ends otl the beams Y Y are connected together by a strut, Z, connected at mid-length by a rod, c, to the lever b. When this lever is drawn forward., the plows W W are raised from the ground. The lever b is held in the forward position by catches c on a bar, d, at the side of the lever. t is a spring, which rests on the lower arm ofthe lever b, and, by holding the said arm forward, tends to hold the plows W W in the ground. ff are the lever-bars of a brake, by which the rotation of the wheels may be stopped at any time, so as to cause the wheels to slip upon the ground as the implement is drawn forward, to nia-ke the corn dropping to correspond 'transversely with the rows previously dropped.

For instance, supposing the dropping to occur a little too early, the Wheels are checked in their rotation, and consequently the dropping made to take place a little later, or farther on in the row. g is the tongue. h h are the singie-trees, connected directly to the saine eyebolts j j to Which the draw-rods T T are connected. l is the drivers seat.

I claim as my invention- 1. The seed-boxes M, secured to the frame, and having the axle-shaft B passing through them, in combination with the seed-dropping device D D, as and for the purpose set forth.
