CHECK-ROWE R FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 335,361, dated February 2, 1886. Application filed September 12, 1585. Serial No. 176,952. (No model.)

.To all whom it may concern.-

Be it known that we, G'us'riivus W. JnwnLL and ROBERT M. DICKSON, of Earl Park, in the county of Benton and State of Indiana, have invented a new and useful Improvement in Check-Rowers for Corn-Planters, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a plan view of our check-rower for cornplanters; Fig. 2, a longitudinal central section of the same; Fig. 3, a perspective View of the feed-bar attachment detached; Fig. 4, a plan view of the cam detached, and Fig. 5 a diagram showing the movement of the trailing wheel.

The presentinvention relates to an improved check-rower for corn-planters,wherein we provide colter-wheels which cut through the clods and upper surface of the soil, so as to permit the measuring to be done more equally than if the wheel had a broad tire; and also in having a cam consisting of two members on the aXleshaft, and engaging therewith a pair of friction rollers and levers so disposed as to operate above the feed-bar and rearwardl y a trailing wheel, so that a mark may be made centrally between the rows corresponding with the space of the hills, all of which will now be set forth in detail.

In the accompanying drawings, A represents the framework of an ordinary corn-planter and check-rower; B, the axle, and Othe pole.

In place of the ordinary folly-wheel to attach to the axle B, we provide colter-wheels D, formed of a metallic disk with a sharp cutting-edge, E, or, what might occasionally be preferred, constructed as an ordinary spoke wheel, but having the felly formed of a flat metal rim set on a plane corresponding with the spoke.

Inwardly each end of the frame A is provided with the planter-shoes F. Above this frame the usual feed-bar, G, is provided.

Upon the rotating axle-shaft B we provide a cam, H, formed in two sections or members, with somewhat of a space between them, and adjustable upon the said axle-shaft by means of set-screws I. The inner face of these members has a raised shoulder, H, extending around nearly one-half of the face, while the opposite member has also a corresponding raised surface, so that when placed opposite each other, as shown in Fig. 4, the frictionroller placed therein and attached to the lever y will have a reciprocal motion when the shaft B is rotated. Rearwardly from this cam H we provide a vertical metallic support, J, secured to the frame A by means of the forwardlyprojecting wings L and M at the upper and lower part of this piece. The upper wing, L, has a lever, N, journaled thereon and projecting slightly forward, with the friction-wheel O journaled vertically thereto and resting within the recess between the two members of the cam H, while at the same time the opposite end of the lever N projects rearwardly and operates within a vertical keeper, I, of an adjustable attachment, Q, on the feed-bar G. The lower wing, M, of the support J has also a lever, B, the forward end provided with a friction-roller, S, also resting within the spaces between the members of the cam-wheel H. This lever also projects rearwardly some distance and connects by means of a crossbar, T, with a bar, U, parallel with the said lever B, and hinged forwardly to the under face of the frame A, and carrying a trailing wheel, V, centrally beneath the device.

Immediately forward of the trailing wheel V, I provide a rearward]y-projecting arm, X, hinged to the frame A, having rearwardly a transverse scraper, Y, so that the clods may be removed and thus leavea level surface for the trailing wheel V to do its work more perfectly. As the device moves forward, the rotation of the axle-shaft B, engaging with the roller 0, operates the lever N in one direction, while the lower lever, B, having forwardly the friction-roller S, also engaging with the said cam, operates in the opposite direction. This upper lever, N, thus operates the feed-bar G, extending into the seed-boxes over the plantershoes F, (not shown in the drawings,) and the lower lever, B, having lateral motion rearwardly, causes the trailing wheel V to act as a marker, as shown in the plan, Fig. 5, by the dotted lines W. This trailing wheel V is thus diverted laterally at regular intervals, so as to correspond with the location of the hill.

The colter-wheel D is arranged so as to be used for cutting through the clods and upper surface of the soil, and thus permit the measuring to be done more equally than if the wheel had abroad tread, and thus moved over the top of the clods and uneven surface of the ground.

Having thus described our invention, what we claim as new is 1. The combination in a check-rower for corn-planters, of a pair of levers, .one connecting with the feed-bar and the other with the trailing wheel, with a swivel cam-wheel on the axle-shaft whereby one lever operates the feedbar while the other diverts the trailing wheel to form a mark diverted laterally at regular intervals.

' 2. The combination of the frame A, the Wings Land M, carrying thereon thelevers N and R, the keeper P, the feed-bar attachment Q, the trailing wheel V, and leveling-scraper Y, substantially as herein described.
