UNITED STATES PATENT OFFICE;

MARION 'I. BROADY, or BARTLE, INDIANA.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 367,781, dated August 9, 1887.

Application filed May 13, [857.

To (tZZ whom it may concern.-,

Be it known that I, llTARlON 'l. BROADY, a

citizen of the United States, residing at Bar-.

tle, in the county of Vashington, State of Indiana, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification, reference being had therein to the accompanying drawing.

This. invention has relation to corn-planters, and hasfor its object, among other things, the provision of a planter that can be manufactured at a minimum cost, that is light and durable, and the dropping mechanism of which can be thrown into and out of operation. 1 Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed the planteiywhichis of ordinary construction,

and provided with the longitudinal parallel bars A, connected at their forward end to a transverse bar, A and to the front of the frame is connected the usual draft-polc, A J ournaled in bearings A is the axle. A, adapted to rotate therein by means of the ground-wheels A, mounted thereon.

Mounted upon the axle and rigid therewith is a gear, B, and at each side thereof are mounted sliding collars B, connected by means of curved levers B pivoted to each other above the gear, as at B, and connected at their upper ends byachain, B, an arch, B mounted on the bars A, being also pivoted at B to said levers, and serving to maintain the same in a vertical position above the gear B. Thelower ends of the levers are bifurcated or yoke shape, and are mounted in grooves formed in the collars B. Extending laterally from the collars B are rods B, at the outer ends of which are secured collars or clamps B, mounted in grooves in sleeves BF, mounted upon the axle between the frame-work and the wheels, said Serial No. 238,059. (No modelJ' tween the lovers B serves to normally maiir tain the same spread, and consequently the toothed sleeve B irrmesh with the hub B, and thus the planter being drawn along causes the gear B to rotate.

, 0' represents the drivers seat, which is mounted at the rear end of t-he'frame A, and the chain B of the levers B is within easy access thereto, so that by pressure of the foot upon said chain the levers will be inwardly drawn and the sleeve B will be thrown out of mesh withthe hub B", whereby the rotation of the -gear B and the operation of the planter,

which is driven thereby, ashereinafter described, ceases.

In front of the gear B, in suitable bearings, is atransverse shaft, D, formed with cranks D at its ends, and provided at its center with a gear, D adapted to mesh with the gear B, and be driven thereby.

At the front of the frame-work, and at each I side thereof, is arranged suitable seed-dropping mechanism, and in this'instance it com prises a hopper, E, the bottom of which is formed with a longitudinally-slotted plate, E, having a perforated slide, E connected with and oscillated by the crankshaft D by means of a pitman, E and registering with a seed spout or tube, E, projecting down and between and in rear of a bifurcated shoe or runne'r, E", provided'with a rear brace, E".

Sighirposts F, mounted at each side of the frame-work, serve as a means by which the driver may maintain the planter in a straight line with similar posts set in the land at suitable points.

A marking-bar, G, having a marker, G, at its end, and pivotally connected to the framework, as at G is provided at the front of the frame-work, and may operate at either side of the machine, it being supported,whenlowered to position, by means of brackets G, secured to the ends of the frame and projecting therefrom. Both of the sides of the marker G terminate in bifurcations, whereby a more visible mark is made than would be by the edge of the marker itself.

For thepurpose of providing means whereby the front of the planter may be elevated, so as to allow the runners and seed-dropping'mechanism to pass over obstructions, and thereby preventing straining and breaking said mech anism, I have provided a tilting frame, If, pivoted as at H, projecting beyond the front of the machine, and provided with a casterwheel, H journaled therein. Alight frame, I, mounted upon a shaft, 1, secured to the bars A, the forward end resting under the rear end of the frame II, serves as a means for raising said rear end of the frame II, and consequently the front end of the frame-work of theplanter. After being connected to the rod I the frame I is downwardly, rearwardly, and upwardly bent, as at 1*, so as to passin rear of the gear B, and within easy access to thcfoot of the oporator, the operation of raising the planter being to press downwardly upon the rear end of the frame I, which will perform the function and operation heretofore described.

Having described my invention and its operation, what I claim is 1. In a corn-planter, and in combination with the axle and groundwheels thereof, the hubs of the latter provided with teeth, a gear mounted on said axle, collars and sleeves mounted at each side thereof, the latter having teeth and levers crossing and pivoted to each other and mounted on the collars, and rods connecting said collars to said sleeves, substantially as specified.

2. The combination of the frame-work and axle of a corn-planter, the latter provided with a gear at its center, and with groumlwvheels having teeth at their inner ends, toothed sleeves mounted on the axle between the hub and frame-work, andlevers crossing and pivoted to each other and connected by a chain for throwing the sleeves intoand out of connection with said hub, with a crank-shaft having a gear, and seed-dropping mechanism connected with said shaft, substantially as specified.

3. The hopper E, having the slottcdbottom E, the perforated slide 15', the pitman E, and mechanism for operating the same, in combi nation with the bifurcated runner E, the brace E, depending from the frame and connected with each side of the runner, and the seed-tube I substantially as specified.

4. In a corn-planter, the combination of the framework A, the tilting frame II, pivoted, as at II, thereto, and having the caster II", with the frame or lover I and rod l7, substantially as specified.

5. The frame A, in combi nation with the axle A, having the wheels A and gear B, the

collars B slccvesll the rods I) the dates 3, the lovers B connected as at 11" and 1;, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

MARION '1. BROADIY.
