UNITED STATES PATENT OFFICE.
EVERELL A. JOHNSON, OF BRADY ISLAND, NEBRASKA.
CORNQ-PLANTER.
SPECIFICATION forming part of Letters Patent No. 429,532, dated June 3, 1890.
Application filed February 6, 1890. $erial No. 339,376. (No model.)
To all whom it may concern:
Be it known that I, EVERELL A. JOHNSON, a citizen of the United States of America, residing at Brady Island, in the county of Lincoln and State of Nebraska, have invented certain new and useful Improvements in Corn-Plane ers; and I do hereby declare the following to specification.
My invention relates to corn-planters; and it consists in the improved construction hereinafter described and set forth, whereby a simple and efficient arrangement is provided that is serviceable and positive in operation.
In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a corn-planter embodying my improvements. Fig. 2 is a rear elevation there- 'of, and Fig. 3 is a sectional View.
The frame consists of a transverse bar a, to which a bar I) is rigidly connected by means of converging braces c c. The seed-hoppers A are located on the bar a, adjacent to each end of the same, and have on their under sides a plate or guide, in which plays a transverse bar B, the end portions of which constitute the seed-slide of the hoppers. The bar a has projections e 6, against which lugs f, depending from the under side of the bar B, contact, in order to limit the reciprocations of said bar. -Centrally mounted upon the upper side of the bar B is an arm 0, the end portion 9 of which is bent horizontally.
The hoppers A carry on their rear sides boxes h, which are bolted in position and within which bears a transverse shaft or axle C, of a length twicethe width of the space between the hoppers, and on this shaft, outside of but adjacent to each hopper, is keyed a main carrying-wheel D, the spokesz' of which have their ends projecting beyond the periphery of the wheel in order to secure proper traction therefor. An annular ring j is secured on the sides of the spokes, and is provided with a cam-shoulder k, guarded by parallel ribs Z.
a horizontal extension m, upon which is mounted a short vertical plate n, having a vertical slot 0, in which plays a web 19, at-
tached to a horizontal rod q, the inner ends thereof being bent to engage the hook of the arm, while the outer end of arod plays through a vertically-perforated ear 0" on the outer edge of the hopper. Each of said rods is provided over each hopper and adjacent to the vertical slotted plate with a block 8, to which is attached one end of a coiled spring t, the other end of which is connected to the adjacent ear ror other fixed part of the machine.
It will be noted that the cam-shoulders on the carrying-wheels are relatively located diametrically opposite to each other, and that the position of the rod is designed to be such thatone end of the same is to be engaged by either of the cams and vibrated twice for each complete rotation of the carrying-wheels.
In operation the oppositely-located cams successively contact with the respective ends of the rod, each of the said ends being guided upon the cam by the parallel guide-strips before mentioned. Now as the cam forces the rod to one side the spring of the other rod, which has been previously distended by the opposite cam, acts to shift its rod ontward, and through its hook engagement with the arm shifts the seed-slide in the same direction, a corresponding operation taking place and the slide moved in the reverse direction by the other cam. The outer ends of the shaft O carry marker-arms H, which revolve therewith to score the earth and indicate the 10- verse bar, seed-hoppers located on the same,
Each hopper carries at its upper inner edge together with a main axle, carrying-wheels provided with cams, a seed-slide bar reciproeating in guides below thehoppers and carrying centrally a vertical arm provided with a bent end, and independent rods playing in guides located on the hoppers and engaging said arm and actuated from the cams of the carrying-wheels, substantially as set forth.
2. The combination, in a corn-planter, of the supporting-frame provided with a transverse bar, seed-hoppers located on the same.
at each side thereof, together with a main axle, carrying-wheels provided with cams, a seed-slide bar reciprocating in guides below the hoppers and carrying centrally a vertical arm provided with a bent end, independent rods playing in guides located on the hoppers and engaging said arm and actuated from the cams of the carrying-wheels, and blades or EVERELL A. JOHNSON.
