PATENT. OFFICE.

CHARLES soHoLz, on DAYTON, OHIO.

SPECIFICATION forming part of Letters Patent No. 244,771, dated July 26, 1881.

' Application filed May 13,1881. (ModelJ 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 1 is a top plan, Fig. 2 is a longitudinal sectional view, Fig. 3 is a side view, and Fig. 4 is a'bottom-plan view, of my invention.

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

This invention relates to grain-drills; and it consists in a device or combination of parts by which the drag bars may be adjusted to a straight orzigzag line at will of the operator, as will be hereinafter more fully described, and particularly pointed out in the claims.

The invention is an improvement on the patent granted to Charles F. Scholz on August 14, 1877, No. 194,268.

In the drawings hereto a'nnexed,A represents the frame of a grain-drill, the sides of which, B B, are provided with boxes 0 O for the transverse adjusting-bars D E. The front one of these, D, is provided with spindles F, sliding longitudinally in slots Gin the said boxes. The rear bar, E, has suitable spindles mounted in bearings in the boxes 0. The bars D and E are connected, as shown, by hinges H, so that when they are turned in their bearings the front bar, D, will slide longitudinally in the slots G, as indicated in dotted lines in Fig. 4 of the drawings.

I I are the drag-bars, which are forked at their front ends, as shown at J One of said drag bars is connected to bar D and the other to bar E in the following manner: The adjusting-bars are provided at opposite ends with cranks K, having slots L, in which one arm of the forked ends of the respective drag-bars is pivoted, the other arm of each drag-bar being pivoted to a staple, M, upon the respective adj listing-bar. Intermediate drag-bars may be used, pivoted alternately to the bars D and E.

Pivoted to the crank K of one of the dragbars is a lever, N, having notches O O, adjustable upon a stud, P, upon the side of frameA for the purpose of retaining the transverse bars in any position to which they may be adjusted. To operate the said lever N, I avail myself of a second lever, Q, pivoted thereto, and having a slot, R, sliding upon a stud, S, upon the side of the'frame. The slot enables the said arm or lever Q to be lifted, so as to raise the notched lever N ofi stud 1?, when the desired adjustment may be readily accomplished.

This invention is simple, inexpensive, and easily applied and operated.

Having thus described my invention, 1 claim and desire tosecure by Letters Patent of the United States- 1. The combination of the frame A, boxes 0, having slots G, transverse bars D E, hinged together, and having slotted cranks K, and staples M,the forked drag-bars I, and operating mechanism, as herein described, for the purpose set forth.

2. In a device for adjusting the drag-bars of grain-drills, the combination, with the adjusting-bar having crank K, and frame A, having studs P S, of the notched lever N, and the slotted lever Q, all arranged and operating substantially as herein described, for the purpose shown and specified.

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

CHARLES SOHOLZ.
