WITNESSES 'NITED' STATES LLOYD C. STALNAKER, OF YORK, PENNSYLVANIA.

CORN AND SEED PLANTER.

EdPECIl-"ICATIGN foaming part of Letters Patent No. 337,795, dated March 9, 1886.

Application filed October 3, 1885. Serial No. 175,939. (No model.)

To all whom, it may concern:

Be it known that I, LLOYD C. STALNAKER, a citizen oft-he United States, residing at York, in the county of York and State of Pennsylvania, have invented a certain new and useful Improvement in Corn and Seed Planters, of which the following is a full, clear, and exact description.

This invention relates to seedplanting machines of the class in which the seed, usually kernel by kernel, is taken from a mass and carried to a chute by which it is conveyed to the prepared ground; and my invention has special reference to machinery for planting corn, peas, and such like large kernels; but, as will appear, it is readily applicable for planting the cereals generally, and also smaller seeds.

The invention consists in a bed-plate having a central dome, a lateral discharge-opening, and a positively-driven annular feeder having inwardly-projecting seed-cells which carry the seed to and drop it through the dischargeopening, as I will now proceed to particularly set forth and claim.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure l is a top plan view of an approved form of my invention for use as a cornplantcr. Fig. 2 is a top plan view of the same with the hopper removed, and showing one form of the feeder. Fig. 3 is a top plan view of the bed-plate. Fig. at is a vertical section in the plane of line 00 m, Fig. 1, show ing another form of feeder; and Fig. 5 is a sectional perspective of the annular feeder detached.

Inasmuch as the driving mechanism, frame, boot, and mountings will be of any approved form, and are not of the essence of this invention, I have omitted them from the drawings and this specification.

The bed-plate a (see Figs. 3 and 4 for details) has the central dome, b, rising from it, and supported by the depressed bridges c, a well or annular opening, cl, being made between the dome and bed-plate. This dome b has at its base a horizontal flange, e, at the foot of an upright shoulder,f, of the dome, and in this flange is made the discharge-opening g. The outer edge of the well or opening d has a rabbet, 72, which receives an annulus, 2', the lower side of which is provided with teeth to be engaged by a pin ion to rotate said annulus in its rabbet in the bed-plate in ordinary manner. The inner edge of said annulus has the seed-cells k, to receive the seed and carry it, as the annulus is rotated, to and drop it through the dischargeopening g. The inner portion of this annulus has a bearing upon the flange e of the dome Z), and its inner vertical edge has a hearing or loose iit on the shoulder f of the dome, so as to keep the annulus in place.

The shape and number of the cells in the annulus will be determined by the kind of seed to be planted, and to adapt the planter to several kinds of seed the annulus may be made removable; or, instead of being in one piece with the gear portion, as in Fig. 2, the latter may be a separate piece, and the cellu lar annulus be rcmovably placed therein, as in Fig. 4. This cellular annulus of either form is herein referred to as the feeder.

-Z is a hopper-base arranged upon the bedplate, and mounted thereon in any suitable manner, as by a hinge, m. This hopper-base has the inclined or shelving portion a, which rests upon the feeder to aid in holding it in place. The portion a is preferably separated from the body of the base by a space, to save weight and metal in casting.

0 is a wall or diaphragm thrown across the hopper to separate the dischargeopening from the compartment containing the seed, and this wall serves also as a scraper for the feeder as it rotates beneath it.

The hopper is finished out to proper size, or by a sheet-1netal tube, 19, secured to the hopper-base, as by a bayonet-joint, as indicated by dotted lines in Fig. 4., or any other suitable fastening.

The operation is obvious: The hopper being supplied with seed, the kernels will fall into the cells k, and the rotating annulus will carry them around until the cells come successively over the opening 9, when they, having no support, will drop out and be carried to the earth.

That I claim is-- 1. In a seed-planter, a rotating feeder comprising an annulus having seed-cells in its inner edge, substantially as described.

2. The annular feeder having seed-cells in 2 4 asi'i its inner circle, and a rotating annulus in which it is supported and by which it is driven, substantially as described.

' 3. In aseed-planter, the bed-plate a, having a central dome, b, a surrounding Well or opening, d, a lateral discharge, 9, and bridges c, to connect the dome and bed-plate, substantially as described.

4. In a seed-planter, the bed-plate a, having a central dome, I), provided with a horizontal flange, and the lateral discharge-opening, g, a vertical shouldenf, and a surrounding rot-ating feeder provided with internal seedcells, substantially as described.

5. In a seed-planter, the bed-plate having a central dome provided with a horizontal
