CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 261,279, dated July 18, 1882. Application filed April 11, 1882. (No model.)

To all whom it may concern:

Be it known that we, JAMES M. TOY, THOMAS D. Tov, and NELSON .ToY, all of Washburn,"

in the county of Woodford and State of Illinois, have invented a new and useful Improvement in Check-Row Attachments for Corn- Planters, of which the followingis a specification.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference in dicate corresponding parts in all the figures.

Figure 1 is a plan view of our improvement. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan view of a modification of the same.

The object of this invention is .to facilitate the planting of corn in accurate check-rows.

The nature of this invention consists in the combination and arrangement of parts, substantially as hereinafter fully set forth and claimed.

A represents the crossbar of a planter-frame,

-to which the seed-boxes B are attached.

0 is the slide by which the seed is removed from the seed-boxes B and'dropped to the ground.

of the frame, is attached across-bar, E, the ends of which project beyond the sides of the planterframe.

To each end of the bar E are pivoted two guide-pulleys, F, between which the cord or wire G passes. The cord Gextends across the field, and is provided with knots or knobs H to operate the seed-droppin g mechanism.

To the cross-bar E, upon the opposite sides of its center, are pivoted two levers, I J, the

upper ends of which are forked in such a manner that the said levers will be turned by the knots of the cord G, but will allow the smooth parts of the said cord to pass through the said forks freely.

To the lower end of the forked lever I is pivoted the outer end of a rod, K, the inner end of which is connected with the inner end of the rod L by a right-and-Ieft nut, M. The outer end of the rod L is pivoted to the upper part of the forked lever J or to an upwardlyproject-ing arm attached to the said lever.

With this construction the operator, by turning the right-and-Ieft nut M, can adjust the forked levers I J to cause the hills to be planted wider apart or closer together, the knots H upon the cordGr being placed at a corresponding distance apart.

To a clamp, a, secured by aset-screw, b, to the lower part of the forked lever J, is pivoted the upper end of a rod,-N, the lower end of which is pivoted to the seed-dropping slide 0. With this construction, as the planter is drawn forward in the direction of arrow 1 the cord G will be drawn across the machine in the direction of arrow 2. As each knot H strikes the forked upper end of the lever I it turns the said upper end to the rightand then passes on. This movement of the forked lever I moves the upper end of the forked lever J to the left, so that it will be in proper position to be struck by a knot, H, of the cord G and turned to the right, which movement of the forked lever J turns the upper end of the forked lever I to the left ready to be operated by the next knot H. Each movement of the levers I J moves the slide 0 and drops the seed, so that the hills will be at a distance apart equal to To the seed-boxes B, or to arms D attached to the said seed-boxes, or other convenient part the distance apart of the knots H on the cord G. v

The lower part of the forked lever J may be perforated with a number, of holes, or may be slotted to receive the pivoting-bolt of the rod N, so that the upper end of the said rod can be adjusted nearer to or farther from the pivot of the said forked lever J, to give a longer or shorter movement to the seed-dropping slide 0, as-may be required.

If desired, the upper end of the rod N can be connected with the right-and-left nut M, or the rod N can be omitted and the inner ends of the rods K L connected with the seed-dropping slide G, which receives the same movement in either case. These different arrangements adapt the attachment to be applied to any of the ordinary corn-planters.

In case a wire be used for operating the seeddropping mechanism the pulleys F can be detached and a threearmed bar, 0, pivoted to each end of the cross-bar E. The bar 0 has a pulley, P, pivoted to each of its opposite arms and a pair of pulleys, Q, pivoted to its ICO rod K L, one section having a right-hand screwthread and the other section a left-hand screwthread, and said sections united by an adjust- 15 ing-nut, M, pitman N, and seed-slide 0, substantially as and for the purpose set forth.
