CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 300,806, dated June 24, 1884:.

Application filed September 8, 18S3. (No model.)

To a/ZZ whom t may concern/A,

Beit known that I, WILLIAM A. SHARPE, a citizen of the United States, residing at Tama, in the county of Tama and State of Iowa, have invented a new and useful Corn-Planter, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to corn-planters, especially of that class composed of hinged or jointed sections, adapted to be independently thrown out of operation; and its object is to provide a planter possessing superior advantages in point of simplicity, ease of. operation, and general efliciency. f

In the drawings, Figure l is a side view of my improved planter. Fig. 2 is a top view ofthe same. Fig. 3 is a front end View of the same. Fig. 4 is a vertical longitudinal sectional view. Fig. 5 is avertical transverse detail sectional view taken through the flexible or hinged bar and looking rearwardly. Fig. 6 is a detail sectional view taken on the line .fr a0, Fig. 2. l

Referring to the drawings, A designates the frame ofthe machine, which comprises in its construction forwardly-convergent side bars, B B, between the front ends of which the tongue or pole VC is pivoted, the wheels D D being journaled at the side of said frame, and the seat E being secured at its rear end.

F designates the transverse bar that carries the seeding mechanism. This bar consists of 'a central portion, G, to which are connected two end sections, H H, bya exible hinge or other suitable joint that will admit of said end sections being thrown up out of operation without interfering with the position of the central section. Each of these sections carry a hopper, I, having its open bottom J arranged over a reciprocating` slide, K, that moves in a groove, L, in the bar F over a seedopening, M, a shoe, N, being secured to the bar at this opening. These slides K are connected by rods O, that have a hinge or flexible joint, I), at the joints Q of bar F, and the seed-slides are adapted to be reciprocated by means of a short rock-lever, R, fulcrumed on the rear side of. the central hopper, as shown at 15, and having its lower end, R', engaging a plate, S, projecting rearwardly from the central slide, K, as shown. A suitable seat is to be provided for the dropper,who operates the lever R. The central section, G, is hinged to the tongue or bar C by means of plates T T, that project forwardly from said section G, and are hinged to the tongue in front ofI its pivot. By means of thisarrangement the said section G can be adjusted vertically under the frame A,to regulate the depth ofthe plant and to enable the shoes to be entirely elevated from the ground in turning, so that they will not become clogged. As the end sections are carriedby the central sections, the adjustment of the latter of course correspondingly adjusts said end sections. The adjustment of the central section, G, is effected by means of a lever, U, that is fulcrumcd to one of the sides B B,`Aand has a segmental lower end,V, formed with a grooved periphery, WV, terminating in a perforation, X. This lever is connected with a corresponding segmental disk or stub-lever,

Y, fulcrumed on the 'other side piece B of frame A by means of an arched connectingrod, Z, that engages a plate, A2, projecting from the rear end of the tongue, to limit the downward adjustment of the said central section, G. Cords or chains B2 B2 are secured to this section G, and proj ect upwardly, are seated in the guide-grooves XV IV, and have their free ends passed through the perforations X X and secured therein by a peg, C2, by removing which the cords can be adj usted in the perforations to regulate their relation to the section G. Each end section of bar F is provided with an elevating-cord, D2, that passes up and through an eye, E, on top a standard, G2, projecting up from the end of the central section, G. These cords or chains D" D2 are se-.

cured to the bifurcated edge FZ of plates H2 H2, that are secured to the ends of levers I2 I2, fulcrumed to the side bars, B B. W'hen either of these levers are lowered, the connected cord or chain is received into its bifurcated edge F2, and the end section, to which it is connected, is elevated on its hinge or flexible joint with the central section. By this means one, two, or three rows may be planted, as desired, by simply operating the necessary levers.

IOO

I claim as my inventionl. As an improvement in corn-planters,'the combination of the frame of the machine, the central section of the transverse seeding mechanism bar hinged to said frame and vertically adjustable in relation thereto, the end sections of said bar hinged to the central section and carried thereby in its vertical adjustment, and means for independently adjusting the end sections, substantially as set forth.

2. As an improvement in corn-planters, the combination of the frame of the machine, the central section of the transverse seeding mechanism bar having thevertical standards at its ends, the end sections of this bar hinged to the central section, the seeding mechanism arranged directly on these sections and embodying a jointed slide-bar, the cords passing from the end sections up and engaging the standards, and the levers fulcrumed ou the mainA frame vand operating these cords, snhstantially as set forth.

' 3. The improved corn-planter, comprising the combination of the frame of the machine, the transverse jointed har carrying the seeding mechanism, a hinged plate or hars hinged to the frame and secured to the central section of the said transverse har, standards on the end of the central section, the levers Il, fulcrumed on the frame, and having the projecting plates or arms, chains, or cords secured to the endv sections and passing through the standards and secured to said levers I, and the lever U, carrying the chains or cords that are connected with the central section, substantially as and for the purpose set forth.

4. As an improvement in corn-planters, the combination of the frame of the machine, the pole or tongue, the central section ofthe transverse seeding mechanism bar, plates T T, se cured to said har and pivoted to the tongue, the levers U and Y, fulcrumed on the frame, the rod Z, connecting these levers and engaging thel end of the tongue, cords connecting the said levers with the said central section, the end sections hinged to the central section, the levers I2, fulcrumed on the frame, and the cords connecting these levers and the end sections, substantially as set forth.V

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

VILLIAM AUSTIN SHARPE.
