and useful improvements in cotton choppers.

and has for its object to provide an implement of this nature which will be simple in construction and cheap to manufacture.

Another object of the invention is to pro.- vide a machine to which cultivators may be easily attached so that cotton may be thinned and cultivated at the same time.

The invention also aims to generally improve implements of this nature to render them more efficient and commercially desirable.

With these and other objects in view, as shall become apparent as the description proceeds, the invention consists in, certain novel constructions and arrangement of parts as I shall hereinafter fully describe and claim. v

For a complete understanding of my invention reference is to be had to the following description and accompanying drawing in which- Figure 1 is a side elevation of my improved cotton chopper, one wheel thereof being removed. Fig. 2 is a top plan view of my invention. Fig. 3 is a detail perspective view of the flanged rim used in connection with my device. Fig. 4 is a detail perspective view showing the method of connecting the drive rods to the main frame. is a perspective view of the secondary frame which supports the chopping pole. Fig. 6

is a detail front elevation used to prevent the drive undue distance.

Referring to the drawings by numerals 1 designates wheels rigidly secured to the axle 2.

3 is an essentially rectangular frame having the side bars 4 and end bars 5. The frame is secured near its rear end to the axle 2 by suitable boxings 6 and supports Ia seat 7. A tongue 8 is connected to the |front of the frame by the hounds 9. Cultiator shovels 10 are of the carriage .front end above the Fig. 5'

rods separating an secured to the down wardly extending brackets 11 which are fixed t0 the side bars 4 of the frame 3.

Runners 12, connected at their front ends in spaced relationship by the cross-bar 13, are detachably connected to the front bar 5 of the frame 3 by the hook 14 and chain 15. A frame 16 comprising the parallel crossbars 17, the parallel longitudinal bars 18 and the parallel uprights 19 is secured at its runners 12 by the standards 20. A pair of to the front ends the rear uprights 19, holding the frame 16 firmly in position. The longitudinal bars 18, which are normally level with and parallel to the side bars 4 of the frame 3, have secured intermediate their ends the U shaped brackets 22. These brackets engage the side bars 4 to prevent lateral movement of the frame 16, while allowing a vertical motion. A rotatable shaft 23 having a cross piece 24: formed on the rear end thereof is secured by the brackets 25 to the frame 16. A double edge hoe 26 is connected by the arm 27 to the shaft 23 and is free to oscillate in a transverse vertical plane. A frame 28 is mounted on the hoe arm 27 and serves to prevent the cotton and weeds when out from falling in the path of the cultivator shovels 10.

To actuate the hoe and cause it to swing from side to side I provide the drive rods 29 and flange wheel 30. The flange wheel 30 is rigidly secured to the axle 2 intermediate its ends and is provided with a removable rim 31 having the angular flanges 32 formed on the edges thereof in staggered relationship. When it is desired to change the speed or frequency with which the hoe 26 oscillates the rim 31 is removed and another having differently spaced fingers substituted.

The drive rods 29 which the wheel 30 to actuate the nected at their front ends to and extend rearwardly in parallel spaced relationship on opposite sides of the wheel 30 and are connected at theirrear ends to the levers 33, whose purpose will be explained later. A supporting rod 34 having its ends secured in the frame 3 supports the rear ends of the drive rods 29. The front portions 35 of the rods 29 are closer to gether than the rear portions 36, there being just enough space between them to allow a cooperate with hoe 26 are conthe hoe arm 27 open at their inner ends.

flange 32 to pass. of one of the flanges 32 strikes a drive rod 29 it causes both rods and the hoe 26 to move toward one side of the frame 3. The succeeding flange being on the opposite side of the wheel 30 causes the drive rods 29 and hoe 26 to swing to the other side of the frame and thus a continuous oscillating motion of the hoe is obtained.

In order to prevent the front portions 35 of the rod 29 spreading when struck by the flanges 32 I provide a roller carriage 37 comprising two pieces 38 of flat metal having the longitudinal recesses 39 which are A bolt 40 connects the. pieces 38. Wheels 41, having grooved peripheries are journaled in the outer ends of the pieces 38 and run on the transverse spaced tracks 42. These tracks are supported at an angle to the horizontal plane by the brackets 42. The drive rods 29 pass through the recesses 39 and are prevented from spreading beyond a certain adjustable width by the end walls of said recesses.

The levers 33 are secured to the frame 3 by brackets 34 and have their arms 35 re movably held to the frame by the locking rings 36. To spread the drive rods 29 so that they will not cooperate with the wheel 30 the lever arms 35 are swung downwardly and inwardly.

The shaft 23 is prevented from moving too far forward or backward by the rods 43 which pivotally connect to the cross piece 24 and to the cross bar 44. The ends of said cross bar 44 are supported by brackets 45.

Levers 46 having hooks 47 formed on their front ends and having their rear ends bent downwardly rearwardly and inwardly and connected by the bar 48, are pivotally mounted on the cross bar 44. These levers are for the purpose of raising the runners 12. The hooks 47 engage under the lifting bar 50 which is secured to the brackets 22 and the bar 48 may be pressed downward by the foot of the operator.

In the operation of the machine described, the flanges 32 striking the driving rods 29 cause the hoe 26 to oscillate from side to side and cut the stalks of the cotton or other plants. The runners 12 counteract any slight unevenness of the ground and retain the hoe at the proper elevation for cutting. I have found that by mounting the hoe on a secondary frame as described a much evener cutting action is secured than is the case when the hoe is carried by the main frame. In crossing from one field to another the runners 12 may be raised and the hoe rendered inoperative in the manner previously described.

It will be understood that while I have shown a preferred form of my invention I do not limit myself to the precise construction shown and described, the scope of my When the beveled edge invention being clearly defined in the appended claims.
