IMPROVEMENT IN COTTON-.SEED PLANTERS.

Specification forming part of Letters Patent N0. 18,104, dated September 1, 1857.

To all whom it may concern.'

Be it known that I, THOMAs J. ROGERS, of Cassville, in the county of Cass and State of Georgia, have invented an Improved Cotton- Seed Planter; and I do hereby declare that the following is a'full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification- Figure l being a side elevation of said planter; Fig. 2, an elevation Of the rear end of the same; Fig. 3, a section in the line x a: of Fig. 2, and Fig. 4 a plan of a detached portion Or the planter.

Similar letters indicate the same parts in each drawing.

The seed-box A A of my improved planter is mounted upon a strong platform, O, which rests upon the axle b of a pair of drivingwheels, B B. The bottom ofthe seed-box is of A such a shape as to ycause the seeds tO incline inward and forward toward a planting-aperture in the front end of said box. The curved front end of the inclined elastic plate f forms the after side of the planting-aperture in the seed-box, and the forward side of said aperture is formed Of a flaring' concavity, k, at the lower end of the plate Z, which is secured tO g, which is made fast to the rear end, A', of the seed-box.

A ratchet-wheel, n, is secured to the central portion of the axle b, and a hardened shoulder, p, is secured to the under side of the plate f in such a position that the teeth of said ratchet-wheel will act against said shoulder, and thereby produce a rapid vibratory movement ofthe said elastic plate f when the planter is drawn forward.

The pointed marker d, which descends from the forward end of the'platform O, forms a drill for the reception ofthe seeds, and the forked scraper e, which descends from the rear end of said platform, covers the seeds 'after they have been deposited in the drill.

The spring-plate f should be Of such a degree of strength and stiffness as will insure its rebounding sharply the instant it is relieved from the action of each one of the teeth of the ratchet-wheel n. My invention therefore consists in forming one side of the eduction-aperture in a cotton-seed planter of the extremity Of a sharply-vibrating elastic plate.

This invention has' been thoroughly and practically tested with a full-sized machine, and has proved itself to be capable of uniformly and perfectly depositing the proper number of cotton-seeds in a drill; and also that the number of seeds depositedcould be varied by changing the position of the concave k, which forms the front side of the planting-aperture.

' What I claim as my invention, and desire to secure by Letters Patent, is-

Forming one side Of the eduction-aperture of a cotton-seed planter of the extremity of a 4sharply-vibrating plate when the opposite sidev of said aperture is formed of an adjustable flaring concave, substantially as herein set forth. Y

The above specification Of my new and improved cottOn-seed planter signed and witnessed this lst day of June, 1857.

THOMAS J. ROGERS.
