IMPROVEMENT IN ACRN PLANTERS.

Specification forming part of Letters Patent No. 146,343, dated January 13, 1S74; applicationiled October 15, 1873.

To all whom it may concern:

Be it known that I, J oHN KELLY, of Troy, in the county of Miami and State of Ohio, have invented an Improvement in Corn-Planters, of which the following is a specication:

The nature of this invention relates to an improvement in the dropping mechanism of y two-horse corn-planters, having for its object to produce, by the movement of a hand-lever, a coincident and positive movement of the rotary dropper-plate in each seed-box, and tov insure the dropping of each charge of seed.

The invention consists in the peculiar mechu anism for operating the dropper-plates, as

more fully hereinafter set forth.

Figure l is a perspective view ot' my improved corn-planter, looking at it from behind. Fig. 2 is a plan of the under side of the dropping-plates and their covering-plates as removed from the main frame. Fig. 3 is a sectional plan of a dropper box and plate.

` Fig. 4 is a cross-section of the brush at x x in Fig. 3.

Like letters refer to figures. y

In the drawing, A represen ts the main frame like parts in the several' 1 v transverselyT mounted on the metallic furrowopeners B, with a seed-spout, C, leading to each from the rear corners of the frame. D is a seed-box at each end of the frame, closed "at the bottom by a metal plate, with a circular dropper-plate, E, pivoted on a stud, a, its rear part rotating through a slot in the rear wall of the box. `Each dropper-plate has a bevelgear, b, near the periphery, underneath,

' with which meshes a pinion, c, at either end of a shaft, F, transversely journaled in the frame, so that motion being given one dropper 1 thef shaft will impart it to the other. Above each dropper in the box is a seed-plate, D', slotted to allow the corn to pass down to the dropper-plate E,'and iill the cells 6, cut in the ,y same near its periphery. A brush, 7c, is secured in each box, through a hole in the plate D', just before the grain issues from the box,

to sweep oft any surplus corn that might otherwise clog` the plate. On the periphery of 'each dropper-plate will be noticed a series of end, which serves as a stop when it enters a notch, f, in the dropper-plate. To the extremities of the bar Gr are pivoted the outer ends of two segments, G', Whose inner ends are pivoted to the lower ends of the studs a, which carry the dropp'enplates. The outer edges of these segments carry two short posts, one ateach segment, to which is pivoted a pawl, j, which engages with the ratchet formed by the inclined planes g on the dropper-plates, and rotates the dropper-plate when the b ar is moved in one direction, but slides back when the bar is moved in the opposite direction. The pawls, stop-notches, and ratchets of the two plates are disposed in opposite directions, so that the bar G, being reciprocated, moves one plate by its pawl, and said plate, through the shaft F and pinions b b, movest-he other plate, bringing a cell full of corn over the opening in the bottom plate, whence it falls through the spout to the ground. A reverse movement of the bar G rotates the other plate, and, through the gearing described, it rotates the opposite one, causing both plates to drop'their seed simultaneously, at a single movement of the lever which actuates the bar G, and with ease and certainty. L i y g '4 To compel each cell. to empty itself of any seed which may have wedged therein, a star wheel, H, is so pivoted behind each dropperbox that one of its arms will always project into the slot that comes under it, and thus force out the corn. i

What I claim as my invention, and desire to secure by Letters Patent, is-u 1. In a corn-planter, the combination of the rotary dropping-plates E, the intermediate shaft F, with bent gears c, and the reciprocatl ing' bar Gr, With its segments G G', all e011-- piuions e c, and provided with the stopmotehe strueted and operating substantially as set fand peripheral ratohets g, the reciprocating forth. bar G, provided with the stops z' i, segments 2. The combination, with the frame A, fur- G G', and pawls jj, substantially as and for rori opener B, and seedspouts C C, of the the purpose set forth.

seed-boxes D D, each provided with a slotted JOHN KELLY. seed-plete, D', a bottom plate, and the rotary Vit-nessesz. dropper-plateE pivoted thereto, the said plates C. C. WEILAND,

E being geared together by the shaft F and L. H. THOMPSON.
