JOHN C. BRYAN, OF FORDYOE, ARKANSAS, ASSIGNOR OF ONE-HALF TO JAMES C. CHEATHAM, OF SAME PLACE.

HARROW AN D CU LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 400,392, dated March 26, 1889.

Application filed July 16, 1888- Serial No. 280,134. (No model.)

dyce, in the county of Dallas and State of Arkansas, have invented a new and useful Improvement in Harrows' and Cultivators, of which the following is a specification.

My invention is an improvement in cultivators and harrows; and it consists in the novel constructions and combinations of parts, as will be herein described and claimed.

In the drawings, Figure 1 is a side view, and Fig. 2 a top plan view, of my improved implement. Fig. 3 is a detail perspective view of one of the standards, showing'also portions of the cross-bars and the brace; and Fig. 4 is a detail rear View of the standard.

To the beam A are pivoted the cross arms or bars B, which may be preferably-formed of angle-iron, as shown, and are connected together, after the fashion of a parallel-ruler, so they will preserve a parallel relation, when turned on their pivotal connections, with the beam. To one of these cross-bars I connect one end of a brace-rod, O, which is provided at its opposite end with a clip, D, embracing and movable along the beam, and which clip may be held in any of its adjustments by means of a clamp, E, formed, preferably, of a wedge driven within the clip and between the same and the beam. This clamp operates, when desired, to secure the clip tightly to the beam, and thus hold the crossbars in position at any suitable angle to such beam and to the line of draft or motion of the implement.

The standards F have portions pivoted to each of the cross-bars, and are preferably each formed of a bar of metal bent upon itself be- .tween its ends, forming upright arm 1 and brace-arm 2, the said arms 1 and 2 being held apart for a short distance from the bend, forming a slot, 4, for the passage of the bolt or bolts which serve to secure the point or shovel 5 at a point, 6, abovethe bending, and at the upper end of slot 4, the brace-arm 2 is twisted, forming a projection which bears against the inner face of arm 1, and serves to hold such arms apart to form the slot 4. From such twist 6 the arm 2 inclines to the rear, thus separating the upper ends of arms 1 and 2, so they may be pivotally connected with, respectively,the front and rear cross=bars. From the upper end of one of the arms 1 and 2, preferably the latter, I project a top bar, 7, which extends between the front and rear cross-bars and forms a connection therebetween.

It will be seen'from the foregoing that in adjusting the cross-bars to different angles the standards will be brought to run closer together, and yet the points or shovels will be at all times held at the same angle to the direction of motion, they in the construction shown being at right angles to the line of mo= tion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A standard formed of a bar of flat metal bent between its ends, forming arms 1 and 2, the arm 2 being twisted at 6 at a point above the bend, such twist operating to hold the arms 1 and 2 apart to form the slot 4, substantially as set forth.

2. The improved standard herein described, consisting of a bar of metal bent upon itself forming arms 1 and 2, the arm 2 being twisted at 6 and inclined rearwardlyabove such twist, and the arm 7 extended forward from the upper end of the arm 2, all substantially as set forth.

3. The combination of the beam, the crossbars pivoted to the beam, and the standards formed of bars of metal bent upon themselves forming arms 1 and 2, the arms 2 being twisted at 6, and such arms being inclined rearwardly above such twist, and the arm 7 projected forward from the upper end of such arm-2, the standard being pivoted to the cross-bars, substantially as set forth.
