To all whom it may concern:

Be it known that I, Roarm'r F. WARD, a citizen of the United States residin at Kingstree, in the county of Williams ur and State of South Carolina, have certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a-full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

This invention relates to straddle row cultivators provided with disks; and it consists in the novel construction and combination of the arts hereinafter fully described and claimed:

In the drawings, Figure 1 is a planview of a cultivator constructed according to this invention. Fi 2 is a rear end view of the same with the andles removed. Fig. 3 is a side view of the cultivator.

The draft. beam 2 of the cultivator is drawn along in any approved way, and it is provided with handles 3 for guiding it. A crossbeam 3 is secured under the beam 2, and it consists of two parallel plates 4 secured together by rivets 5 and distance pieces 6, so that horizontal openings 7 are formed between the plates. The middle part of the crossbeam 3 is secured to the rear end portion of the draft beam by a vertical bolt 9, and 10 a forked and downwardlv and rearwardl-y curved support or arm for supporting the fender disks 11. The fender. disks 11 are journaled on pins 12 at the free end portions of the forked support or arm. The upper end portion of the arm 10 is provided with a, longitudinal slot 14 which permits the position of the fender disks to be adjusted.

Spindles 15 are provided and are adjust able horizontally in the openings 7 of the crossbar. The spindles have nuts 16 at their front ends for securing them to the crossbar, and they have brackets 17 pivoted on the rear end portions. These brackets have vertical bearings 18 on one side of their pivots, and curved slots 19 on the other side of their pivots. Notched plates 20 are formed on or secured to the bottom ends of the bearings18. Bolts 21 lnvente pass through the curved slots 19 and the openin 7 of the crossbar, and these bolts clamp t e' brackets to the crossbar after the bearings have been adjusted on the pivots. The spindles 15 have shoulders or collars 22 which bear lagainst the edges of the plates of the cross- Forked standards 24 are provided, and

they have vertical spindles 25 at their upper,

parts which are journaled in the bearin s 18. The standards 24 are provided wit pins or catches 23 of any approved make for engaging with the notches of the plates 20 after the position of the standards has been adjusted.

The cultivator disks 26 are mounted on shafts 27 in the lower parts of the forked standards 24. These disks are set at any desired angles with the vertical and with the line of draft, by turning the brackets on the spindles 15 and by turning the spindles 25 in their bearings. These disks 26 cultivate the ground on each side of the row of plants. The fender disks also cultivate the ground adjacent to the stems of the plants, and they protect the stems from injury.

What I claim is: V

The combination, with a cultivator provided with a draft beam, and cultivating devices secured thereto; of a continuous downwardly curved plate of substantially uniform width, said plate having a longiheight above the bottom portions of the saidcultivating-devices and permit the slotted plate to clear the growing plants.

In testimony whereof I have aflixed my signature in the presence of two witnesses,

R. F. WARD. Witnesses:
