Application filed July 17.1907. Serial No. 384,158.

To all whom it may concern:

Be it known that I, JOHN HUDSON, a citizen of the United States, residing at Hamlin, in the county-of Jones, State of Texas, have invented certain new and i useful Improvements in Cotton-Choppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will' enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in cotton choppers, and it has more particular reference to a cotton chopper oi that type which includes an oscillating lever carrying a chopping hoe and which is driven by suitable gearing from the traction wheels of the machine.

The invention aims as a primary object to provide novel means for permitting of the adjustment of said hoe to selected positions.

The invention aims as afurther object to provide a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description in which reference is had to the accompanying drawings forming a part ofthis speciication, like characters of reference designating similar parts, throughout the several views, wherein:

Figiue l is a top plan view of a machine constructed in accordance with the present invention. Fig. 2 is a side elevation thereof. Fig. 3 is a front elevation thereof. Fig. 4 is a rear end elevation thereof. Fig. 5 is a detailed view oi a slotted standard comprehended in the invention. Figs. 6 and 7 are detailed end and side elevations of a sliding base embodied in the invention. Fig. 8 is a side elevation of one of the levers embodied in the invention, showing a slot provided in the body thereof.

In the accompanying drawings, the numeral l designates an open frame substantially rectangular which at its iront end, supports a tongue 2 and at its rear end supports a block 3, the spring post 4 having connection with the latter by means of bolts 5, the post 4 carrying the drivers seat 6. At the rear end of the frame a U-shaped casting 7 is supported between the side bars thereof and the post 4 is extended angularly beneath this casting connected therewith The depending legs 8 of the casting 7 are formed to surround the axle 9 and are braced with relation to the frame by diagonal straps l0. The axle 9 carries the traction wheels ll. At one side of said axle, a wheel l2 is splined, the latter being formed with crown teeth 13 and being forced inwardly by an expansive coil spring 14 bearing against the said wheel and against the collar l5 provided on the axle 9. The wheel l2 is formed with an inwardly extending hub 16 about which is engaged a yoke I7, the arm of the latter having suitable connection with a foot lever 18 working about a quadrant 19, the lever I8 being employed to force the wheel l2 outwardly against the tension of the spring 14. I

At the opposite side of the frame to the wheel l2, a longitudinal bar 20 is provided with which is connected a laterally projecting member 2l of substantial U shape, the parallel portions 22 of which are projected through eyes 23, depending-from a laterally slidable plate 24 as guides. The plate 24 is provided at each side thereof, with alined bearings 25 in which is journaled a shaft 26, the latter at its rear end having connection by means of a gimbal joint 27 with an inclined shaft 28, the latter being preferably made in detachably engaged sections and carrying at its rear end a pinion 29 which meshes with the teeth I3 of the wheel l2, the shaft 28 being journaled in a bearing 30 projected laterally from the frame I. The shaft 26 carries at its front end a crank arm 3l from which projects a wrist pin 32.` Surrounding the latter is the sleeve 33 carried by a pitnian 34. Pivotally mounted in a slot 20, at the lront end of the bar 20, is a post 35 which is constructed `with communicating slots 36 and 37 on relatively opposite sides thereof. Fixed to the lower end oi the post 35 is a supporting member 38, and pivoted to the upper end of the latter is a lever 39, the latter being projected through the opposite registering slots 36. The lever 39 is formed between the slots 36 with a longitudinal slot 40, and the pitman 34 is projected through the latter and through the slots 37 in their registering relation. The end of the pitman 34 is engaged in a socket 4l provided upon the end of the shank 42, the latter carrying a hoe 43.

The supporting member 38 has pivotal connection between its ends with a link 44 and the latter is in turn pivoted to a lever 45, which at its lower end is pivoted to the bar 20.

Mounted upon the plate 24, is a bracket 46 having a reduced upper end 47 which projects through a longitudinal slot 48 provided in a lever 49, the latter at its front end being pivoted as at 50 to a bracket 5l, supported from the trame l.

In use, therefore, assuming that the wheel l2 is in mesh with the pinion 29 and the machine is being advanced over the field, the shaft 26 will be rotated through the means described and such rotation will result in oscillating the pitman 34, the pivot oi the latter being located at the point where it passes through the slot 40 of the lever 39. It will be apparent therefore, that the direction and amplitude of oscillation of the pitman 34 will be varied in accordance with the adjustment ot' the lever 39. When the lever 39 is raised or lowered, the pitman 34 is of course correspondingl y moved on the wrist pin 32 as a pivot, and by means oi such movement, the hoeI is set to work at a' greater or less distance from the ground as desired. Should it be desired to cause the hoe to lmiss a hill of cotton in its stroke, the lever 45 is thrown forwardly. Should the row that is being chopped extend in a crooked line the lever 49 is rocked on its pivot 50 and in such action slides the plate 24, the portions 22 serving as guides for said plate in this sliding movement, whereby the hoe is caused to follow the course of the row.

It will of course be understood that the several levers herein specied work about the conventional rack quadrant shown and are provided with trigger operated pawls for engagement with said rack quadrant to hold said levers at selected positions.

The invention is simple in its structural details, inexpensive to manufacture and practical and eicient in use.

From the foregoing description it will be seen that simple and efficient means are provided for accomplishing the objects oi' the invention, but while the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various minor changes may be made in the proportions, shape and arrangement of the several parts, without departing from the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A machine of the type set forth, comprising a frame, a shaft supported thereby, traction wheels carried upon said shaft, a post carried by the frame and formed with communicating slots in all the faces thereof, a slidably adjustable plate, a shaft mounted on said plate, gearing between one of said traction Wheels and said shaft for driving the latter from the former, a crank arm carried by said shaft, a ptman pivoted to said crank arm, a lever pivoted adjacent said post and projected through-a pair of opposed slots, said lever' being formed with a slot between the slots of said post, said pitman being projected through said last named slot, a shank secured to the end of said pitman, a hoe carried by said shank, and means for adjusting said plate laterally with relation to said frame.

2. A machine of the type set forth, comprising a frame, a shaft supported thereby, traction wheels carried upon said shaft, a pivotally mounted post carried by the frame and formed with communicating slots in all the faces thereof, a slidably adjustable plate, a shaft mounted on saidplate, gearing between one of said traction wheels and said shaft for driving the latter from the former, a crank arm carried by said shaft, a pitman pivoted tosaid crank arm, a member secured to said post, a lever pivoted to said member and projecting through a pair of registering slots in said post, said pitman beingl projected through said last named slot, a shank secured to the end of said pitman, a hoe carried by said shank, means for adjusting,l said plate laterally with relation to said frame, and means for adjusting said post on its pivot.

ln testimony whereof, I alix my signature, in presence of two witnesses.

JOHN HUDSON.
