WILLIAM L. SEBRLNG, OF BISMARGK, KANSAS.

HAND CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 236,915, dated January 25, 1881.

Y Application filed July 6,1880. (No model.)

To all 'whom it may concern Beit known that LWILLIAM L. SEBEING, residing at or near Bismarck, in the county of 'Wabaunsee and State of Kansas, have in- Fig. 2 is a vertical section in the plane of the pull-rod, showing the means of operating the seed-disk. Fig. 3 is acletail section diametric to the seed-disk at ct a. Fig. 4 is a detail inside view of one of the legs, with part of the guide-pipe broken away to show the spreader. Fig. 5 is a bottom view of the seed-disk. Fig. 6 is a top view of the same. Fig. 7 is a perspective view of the brush.

A is one leg of the planter, to which is attached the corn receptacle or hopper B, the bottom b of which has a circular recess in a' seed-disk, C. c c are the seed-cavities, which extend completely through the disk or wheel, and are made adjustable by a plate, c', forming the top of the disk and capable of turning on the axis c2 of the disk. The seed-orifices in the plate are made by punching down a tongue, c3, of the metal, which thus forms one side of the seed-cavity.

It will be understood that, to allow of the adjustment of the metal plate without partly closing the seed-cavity c at the side opposite to the tongue c3, the orifice of the plate must extend past the rear end of the orifice c in the disk in the normal position of the plate.

In my improvement the orifice in the plate is cut so long as to leave room for a crescentshaped projection, c4, whose top is flush with the plate, and which stands as a bar to the entrance of the points of the grains below the edge of the plate.

In the bottom of the seed-disk are formed a number of ratchet-teeth, D, which are. engaged bythe tooth e of a pullrod or pawl, E, whose outer end is connected to the leg F, so that on the moving outward of the top of this 1eg.the disk has a part rotation and carries one of the seed-cavities from the seed-hopper into connection withthe discharge-chute Gr, through which the seed enters the tube H and drops between the closed shovels'Il I, (see Fig.

1,) where it is retained until the shovels are spread open, (see Fig. 2,) which is done while the shovels are in the earth, and then the grain drops out.

The bottom of the seed-chute H is made to are outwardly, and in the wider portion so formed is placed an angular spreader, which separates the grain as it leaves the tube and drops it onto different parts of the shovels, thus placing the corn apart in the earth.

K is a pivot-screw, of which there is one upon each side, passing through the side plates and into the leg A. These screws form the pivots on which the leg F Works.

To return to the seed-hopper: L is a spring beneath the pull-rod or pawl E, tending to lift the` tooth e into engagement with the ratchet D. (See Fig. 2.) When the rod is moved inward the tooth e runs along the inclined face ot' the ratchet-tooth D, compressing the spring L.

M is the brush, secured in a holder, N, in which it is capable of vertical movement to compensate for wear. The purpose of the brush is to remove surplus grains from the top of the seed cavity when passing beneath the brush, just before it reaches the dischargechute G.

I am aware that it is' not new to form a seed wheel or disk for. corn-planters with an adjustable plate for regulating the size of the seed-orifices, and having a ratchet on its under side against which an operating-pawl is held by spring-pressure 5 and I am also aware that it is not new to attach to one leg of the planter a conveying pipe with an angular spreader at its lower end, and I do not claim these features broadly; but

'What I do claim, and desire to secure by Lettersv Patent, is-

The combination, in a hand corn-planter, of the legs A F, hopper B, and wheel C, provided with seed-orifices c, movable plate c', tongues 03, projections-c4, and ratchet P on its under side, said wheel being operated by a pawl, E, held in Contact therewith by spring-pressure, pipe H, and angular spreader or grain-separator, all made substantially as and for the purpose set forth.

WILLIAM L. SEBRING.
