IMPROVEMENT IN CORN-PLANTERS.

Specification formingpart of Letters Patent N0. 175,058, dated March 21, 1876 application filed July 19, 1875.

To all whom it may concern:

Be it known that l, THOMAS ELDREDGE, of Cuba, in the county of Crawford and in the State of Missouri, have invented certain new and useful Improvements in Corn-Planters; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawand use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure l is a plan view, and Fig. 2 a side elevation, of my machine. Fig. 3 is a vertical section through the line m m, Fig. 1. Fig. 4 is a perspective view of one of the corn-boxes with dropping-cylinder, spout, and shaft or axle. Fig. 5 shows the construction of the dropping-cylinder.

A represents the frame of my planter, pro vided with suitable boxes on its under side, in which the axle B is placed. On each end of the axle is placed a driving-wheel, 0, provided with a clutch, a, which is feathered on theaxle, and held in gear with the hub of the wheel by means of a spring, b. The clutch is thrown out of gear by means of a lever, E, hinged to the frame A, and having its lower end forked to straddle the clutch in a circumferential groove thereon. The frame A has a longitudinal center bar, A dividing the frame into two parts, in each of which is placed an oscillating frame, A both of said 'frames being hung upon the axle B, and their rear ends prevented from going down below the main frame by the rear cross-bar of each oscillating frame projecting beyond the side bars thereof, and forming stops against the top of the main frame and center bar. G G represent the corn-dropping boxes, having their lower ends made in cylindrical form, and the axle B passing through the centers thereof, and within the same works a cylinder-dropper, made in two parts, D and D, fastened together by two of the four bolts 01, that project from the inner side of the dropper. In the circumference of the cylinder-dropper are formed four holes or recesses, s s, to receive and carry off the corn, one-half of each of said holes being formed in each partof the dropper. The outside part D is stationary on the axle, while the inside part D is loose, and by unscrewingthe bolts 11, that fasten it to the stationary part D, said loose part D may be turned one-eighth of a revolution, and the dropper will then drop twice the number of hills and one-half the amount of corn. G of each corn-box G is hinged or pivoted a chute, H, which is, by a rod, f, connected with the front end of an arm, e, projecting from a shaft, h, which has its bearings in suitable boxes, and runs across the main frame A, the other end of the arm e being, by a rod, f,'connected with a slide, k, within the cylindrical casin g G. The shaft h is providedwith a footlever, h, by means of which it is turned in its bearings. By operating this foot-lever the shaft is turned in its bearings, turning the chutes H, and raising the marking-plows I attached thereto, and at the same time moving the slide k, so as to close the aperture w in the cylinder to prevent dropping. In the bottom of each chute H is a hinged drop or valve, m, connected at its rear end by a rod, '5, with a lever, J, pivoted on the outside of the chute, and the other end of this lever is operated upon by the projecting bolts d, to open the valve for dropping the corn deposited in the chute. As soon as a bolt clears the lever, and the corn has dropped through, the valve closes of its own weight.

For coverers, I use diamond-shaped plows K, each attached to around plow'shank, L, formed with octagon-shaped ends. The plow is fastened to the lower octagon-shaped end of the shank L by means of a plate, 10, formed with a half-octagon groove, and bolts n n, connecting the plow and plate. By the use of these bolts or set-screws the plate 1) is loosened and changed on the shank, changing the plow also, so that the plow will throw dirt either to or from the row; and when the plows are secured either straight forward or at an angle the polygonal standard and grooved-plate connection allows a square bearing, and prevents the plows from turning on the standards, as would Under the cylindrical part be the case if the standard end were round, and the plate made to conform thereto. The upper end of the shank L is placed in a swiveled holder, P, attached to the oscillating frame A, and fastenedby a set-screw, t, by which means the shank can be set in the holder, to bring the plow to any desired distance from the row, and also be raised or lowered, as required. On each shank L is placed a collar, v, formed on the lower rear end of a brace, R, the upper front end of which is flattened, and passed through a keeper, to, attached to the frame A, and a wooden pin, y, holds the brace therein, which pin will break when the plow strikes any obstruction, so that the plow will fall back. On the center of the axle B is secured a finger marker, S, the points of which correspond with the dropping holes in the cylinder. On the fi out ends of the oscillating frames A are footrests W, by means of which said frames may be tilted to raise the cultivator-plows out of the ground.

I do not broadly claim a valve arranged in the chute, which valve is automatically operated by means of said distributor, as I am aware that such is not new.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The dropping-cylinder herein described, consisting of the part D made fast on the shaft or axle B, and the part D made movable thereon, and fastened to the stationary part by means of the bolts d, and having the dropping cups or recesses 8 formed in both parts, substantially as and for the purposes herein set forth.

2. The combination, with the dropping-cylinder D D and chute H, of the projecting bolts March, 1875.
