IMPROVEMENT IN CORN-PLANTERS.

To all whom, it may concern:

Be it known that 1', J. H. 130mm, of Elizal bcthtown, in the county of Hamilton and State I of Ohio,-have invented a new and useful ma chine, an Improvement in Corn-Planters; and I do hereby declare that the following isafull, clear, and exact description of the construction and operation of the same, referencebeinghad to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view. Fig. 2 is a vertical section. Figs. 3, 4, 5, 6, 7, S are sections of parts.

In Figs. 1 and 2, BB is the plow-stock; G D, the plow; I-I, coveriiigilukes; G, conical reservoir; X, handle; I I I, tilting-pins; F, conducting-spout; E, block or bottom.

In Fig. 3, K K is the inner ring; a a, oblong holes; 1), slot.

In Fig. 5, L is the outer or thick ring, andK is the inner. c c are oblong holesin the outer ring, and a. a in the inner ring. Z) is its slot and screw. I I are tilting-pins.

In Fig. 6, G is the conical reservoir, which is turned from right to left by the handle X; L, outer ring; 0 e, cavities; a (1., holes to supply c c with corn.

Fig. 4 is the cap to fit on the conical reservoir.

A is a disk, having a flange, M M, upon its periphery. axis a segmental flange placed from O upward a sut'flcient distance from M M to receive Fig. 6.

q is an opening in II M for the exit of the corn.

t is a slot in the segmental flange.

O 0 is a wire spring, playing in the slot to force the corn out of the holes into the spout; S S, height of corn in the reservoir; 1:, segmental space.

\Vhen Fig. 6 is inserted into Fig. 4: and turned from right to left, the corn falls through the holes a a, Fig. 6, and draws back into the cavities c 0, while passing from O to S, M M, Fig. 4, forming the outside wall, and K K, Figs. 3 and 5, the inside, and is carried up to s. From 8 to v. The surplus or loose corn is shaken off and falls back into the reservoir. Thus struck measure is carried up to '0. From o to qit goes downward and the corn falls toward a a, Fig. 6, and would fall back into the reservoir but for the segmental flange over which the rings pass. The exact measure is thus retained until opposite 9, when it is forced out by the spring 0 0 into the conductingspout F, Figs. 7 and 2.

In drilling, the operation is better performed by using a hopper, n, Fig. 8, in the place of the segmental flange. n, Fig. 8, is set to the disk A, so as to convey the corn through an orifice in A at the point of thehoppern, while the flange M is made without the opening (1, Fig. 4.

Fig. 7 shows the conducting-spout. 11 is the bevel on which the pins II, Fi 6, strike. at is one of the ears 011 which thespout is hinged. E is the block or bottom, which is fast to the stem, Fig. 2. The pins I I are set ahead of the cavities, so as-to act on the spout and deliver the corn in. the bottom resting on the block E and replace itself before the corn is delivered for the next hill in dropping checkrows.

To enable others to make and use my improvement, I will describe its construction.

I first construct a conical reservoir six or more inches in diameter at its base, of sheetiron. I then secure to it a thick cast ring about an inch wide, with oblong holes in it for seed-cavities, and between these I insert holes forthe tilting-pins. I then make another ring of the same width, of tin, with oblong holes to match the thick ring 011 the inside and make it fit tightly. I then solder to it a small tap for a screw, which works in a slot in the outer ring, by which it may be moved for the purpose of making the cavities larger or smaller and securing it fast. I then make a disk of sheet-iron the diameter of the thick ring. I then attach a flange three-iburths of an inch in width, of the same material, and one inch less in length than the circumference of the disk, for the purpose of leaving aplace of exit for the corn to the disk. I then make a segmental flange the same width and one-quarter of the circle in length. In this I cut a slot one and one-half inch in length. I then secure it to the disk from r to 0, Fig. 4:, so as to leave space enough for the rings, as shown in Fig. 5, to pass between. I then set the wire spring 0 0 so as to play in the slot, Fig. 4. \Vhen it is made for drilling, I substitute a hopper in the place of the segmental flange, which I make three-quarters of aninch wide at the top, and circular, so as to fit the ring. I then fasten it to the disk at the lower point of the hopper, and make a hole through the disk for the exit of the corn. In this case I make no such openingin the outside flange. In the center of the disk I make a hole to secure the revolving handle. I then insert the handle 0c, and then attach the whole to the stationary plowhandle. The operator then grasps the handle and by a simple turn of the wrist revolves the droppingrings one space at a time. I then construct a spout and pivot it to the stem of the plow, so that the weight of the upper end will hold the nozzle over the block or bottom E for retaining the corn. At
