CORN-PLANTER.

SPECIFLTCATEON farming part of Letters Patent No. 374,242, dated December 6, 1887.

(No model.)

To all whom, it may concern.:

Be it known that we, SAMUEL M. DRAKE and CHARLEs LINDER, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in A represents the axle, on which yare journaled the usual supporting-wheels, B C.

D represents a pulley or sprocketwheel, which is rigidly secured to the wheel C.

E represents a pair of forward extending bars, which converge at their front ends and arc secured to the aXle A. The front ends of the said bars are secured to the under side of a pair of parallel transverse bars, F. On the ends of the said transverse bars are supported hoppers G, which are provided with the usual dischargeopenings in their lower sidcs,which openings communicate with vertical seedspouts formed in the rear ends of runners H, which project forward from the bars F. The said runners have their front upper ends connected by a transverse bar, I.

K represents a draft Etongue or pole, which has its rear ends arranged between the converging front ends of the bars E and converge to the centers of the bars F and I.

On theinner ends of the hoppers G are secured bearing-boxes L, in which is journaled a shaft, M. On one end of the said shaft is loosely mounted a/wheel or pulley, N, which is connected to the wheel or pulley D by means of an endless belt or chain, O.

To the center of the shaft M is attached a cam-wheel, ]?,which is providedwith a diagonal peripheral groove, It, in opposite sides of which are offsets or shoulders S. From each side of the cani at diametricall y opposite points project tappet-pins T.

U represents a sliding clutcli,which is feathered on the shaft M, and is adapted to engage the pulley N, so as to lock the same to the shaft.

V represents a slide-har,which extends from one hopper to the other, and has its ends reduced in size and passed through openings in the inner ends of the hoppers and bearing upon tliebottoms thereof, and thereby adapted to alternately open and close the dischargeopenings in the hoppers.

Between the opposing sides of one of the bars E and the tongue, just in rear of the crossbars F, are secured bearing-blocks W.

X represents a box or guideway, which is rectangular in cross-section, and is provided at its center with projecting trunnions that are j ournaled inthe box YV. From the upper end of the box or guideway X projects a pair of arms, Z, a suitable space or opening being left between the said arms.

A represents a plunger, which fits in the guideway or box X, and has its lower endpro vided with a weighted taniping-bar, B.

C represents an arin which is pivoted to the upper end of the plunger A', andis provided at its upper extremity with a hook, D. Ata suitable distance below the said hook on the front side of the said arm is an offset or shoulder, E. From the rear side of the said arm, at a suitable height above the upper end of the plunger, is a rearwardly-projecting arm, F', which is adapted to strike against the upper end of the box or guideway X, and thereby limit the downward movementof the pivoted arm and the plunger.

The operation of my invention is as follows: Vhen Athe machine is drawn forward and the clutch is caused to engage the pulley N, the said pulley is caused to rotate by being connected to the driving-pulley D, and consequently imparts rotary motion to the shaft M. rlhis causes the obliquely-arranged peripheral groove in the cam P to reciprocate the slidebarViirst in one direction and then in the contrary direction, and thereby cause the seeds to be dropped from the hoppers into the furrows made by the runners. Inasniuch asthe iappet-pins T are arranged at opposite points on the cam and correspond with the offsets or inclines thereof, it follows that as the cani rotates, the tappetpins successively engage the IOO hook of the pivoted arm C and thereby raise the latter, and consequentl y elevate the plunger in the box or guideway X. Vhen the pin reaches the upper side of its path, as the cam rotates, the offset or shoulder E strikes against t-he hub of the cam and thereby oauses the hook to be disengaged from the tappet-pin, When the plunger and the arno C instantly descend in the guideway or boXX, thereby causing the Weighted tamping-bar to make a depression in the earth to register the point at which the seeds were planted.

Having thus described our invention, we claim-'- 1. In a check-row cornplanter, the combination of the shaft M, the rotati ngcam P thereon, having the oblique slot and the tappet-pins T, the reciprocating slide-bar having the arm engaging the slot, and the vertically-movable plunger guided in a suitable wayand having the hook-arxn C at its upper end, adapted to successively engage the tappet-pins as the wheel P rotates, substantially as described.

2. The combination, in a check-row cornplanter, of the rotating shaft M, having the wheel P to actuate the seed-planting rnechan ism, said wheel being provided with the tap vwheel P, provided with tappet arms T, the

guideway or box X, pivoted in suitable bearings and provided at its upper end with the arm F', the plunger movable vertically in the Vsaid guideway or box, and the arm C, pivoted to the upper end of the plunger and provided with the hook to engage the tappet-pins and the offset or shoulder E', for the purpose set forth, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two Witnesses.
