JOHN G. VAN DYKE, OF CHEYENNE CITY, WYOMING TERRITORY.

.CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 237,420, dated February 8, 1881.

Application filed July 28, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN G. VAN DYKE, of Cheyenne City, in the county of Laramie and Territory of Wyoming, have invented certain new and useful Improvements in Oorn- Planters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure l is a perspective view. Fig. 2 is a top view; and Fig. 3 is a detail view, showing the connection of the front axle to the colters of the seeding mechanism.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to check-row cornplanters; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the main axle, which is supported upon the wheels B B and carries the frame 0, to the front end of which is hinged the front frame, D. The latter frame consists, essentially, of a cross-piece, E, having rearwardprojecting brackets F, by which it is hinged to the front end of frame O. The said brackets F are provided with lateral arms G, which support the usual seed boxes or hoppers, (not shown,) and to which the colters H H are rigidly secured. The latter are provided with slotted bails I I, furnishing bearings for the front axle, as shown, and in which said axle may be vertically adjusted for raising the weighted wheels from off the ground, for a purpose hereinafter described.

The front axle, J, is provided with wheels K K, secured upon said axle and provided at the edges with weights L, which, when the wheels are raised from the ground, shall cause them to turn until the weights shall be at the lowest point, thus causing the machine, after turning at the end of the field, to be always in proper position for starting.

To operate the seed-slide, which reciprocates in the usual manner under the hoppers, I employ the following mechanism: M is a cam-grooved wheel secured upon the front I axle, J, and engaging a finger, N, projecting downward from a slide, 0, and provided, if desired, with a roller or caster to avoid friction. The said slide is mounted in suitable bearings, journaled upon axle J and braced to the front end of frame D, or to one of the colters. To the inner end of slide 0 is hinged a connecting-rod, I, connected at its outer end to a crank, Q, through the medium of which motion is imparted to the seed-slide R.

My improved check-rower is simple, durable, and inexpensive. It is easily operated, and plants in the most accurate manner possible, the weighted wheels of the front frame turning the operating-wheels to the exact position required at each end of thefield.

To raise the front frame while turning the machine any suitable lever mechanism may be employed.

I am aware that an adjustable weighted marking-wheel provided with cams which strike in their rotation the rear end of bent rocking arms which actuate the seed-slide is old, and such I do not wish to be understood crank Q, transverse seed-slide R, front pivoted frame, E, in which said seed-slide is mounted, provided with lateral-projecting plates G, and colters H, rigidly secured to said plates, and having the vertically-slotted bails I l, the several parts constructed and operating substantially in the manner herein shown and described.

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

JOHN CALVIN VAN lDYKE.
