ARTHUR M. FINGH, OF HILLSIBORO, TEXAS.

COTTON-CHOPPER.

Application filed June 10, 1914.

To all whom it may concern:

Be it known that I, ARTHUR M. FINOH, a citizen of the United States, residing at l-lillsboro, in the county of Hill and State of Texas, have invented certain new and useful. Improvements in Cotton-Choppers, of which the following is a specification.

My invention relates to a new and useful cotton chopper, reference being made to my co-pending application, Serial No. 845093, filed June 10, 1914, which application refers to the chopper-head forming a part of my machine, and its object is to provide a cotton chopper that may be used as an at tachinent for an ordinary cultivator, and which will have its cutting member adjustable both vertically and longitudinally off its shaft, so that the operator may regulate the depth of cut, and may shift the cutting member forward or back so as to vary to some extent the point at which it takes effect upon the row.

A still further object is to provide a device of the character described, that will be strong, durable, eilicient and simple and comparatively inexpensive to produce, also one in which the several parts will not be likely to get out of working order.

With the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawings, wherein Figure 1 is a plan view of my cotton chopper. Fig. is a view of the same in side elevation. Fig. 3 is a front view'of the cotton chopper with certain portions thereof broken away. Fig. 4c is a detail view of the chopping member. Fig. 5 is a detail view showing the mounting of one end of the shaft carrying the chopping member, this view being a. section taken upon the line .r-m of Fig. 2. Fig. 6 is a longitudinal vertical sectional view of my cotton chopper.

Referring now more particularly to the drawings, wherein like reference characters designate similar parts in all the figures, the numeral -1 denotes a pair of transporting wheels which are mounted upon the extremities of an ordinary arched axle 2, such as is employed on the majority of cultivators.

A tongue 3 terminates some distance in front of the horizontal center portion of the axle, upon the ends of which portion there are respectively mounted brackets 4, to

which are rigidly secured the rear ends of a pair of frame members 5, which project forwardly some distance in a parallel relation, and are then extended toward each other at a forward inclination, their front ends being oppositely attached to the tongue at a distance from its rear end. The two members 5 are rigidly connected by a brace bar 6 contiguous with the rear end of the tongue.

A bracket 8 is secured to the under side of the tongue at its rear end and constitutes a support for an arch bar 7 transverse of the tongue, and the outturned extremities 9 of the arch bar form pivotal supports respectively for the forward ends of a pair of parallel cultivator beams 10, upon each of which a pair of plow shovels 11 are mounted fast. The vertical portions of the axle and of the arch bar 7 are rigidly'connected with each other at each side of my cotton chopper by a brace rod 19, the two brace rods 12 being convergent from the axle to the member 7, and being extended forwardly from the arch bar 7 to the tongue, to which they are secured as indicated at 12, the point 12 being spaced forwardly some distance from the rear. end of the tongue.

Between the rear portions of the beams 10, there is rigidly extended a cross bar 14, which maintains said beams in a constant spaced relation, and further serves to support certain parts presently to be descriliied. llhe vertical portions of the arch bar 7 are connected in a rigid relation by a cross bar 16 from which an arm 16 extends rigidly downward (see Fig. From the lower end of the arm 16, a pair of horizontal rods 17 are extended rearwardly in a divergent relation, their rear extremities being re spectively secured to the forward ends of a horizontal U-shaped frame 18.

The forward ends of the frame form bearings for a horizontal axle 19, lying beneath the axle 2, and having mounted upon its extremities small ground wheels 20, one at each side of the frame 18.

A pair of intermeshing bevel gears 21 serve to communicate rotation from the axle 19 to a horizontal chopping shaft 22 parallel to the beams 10, the forward end of said shaft being journaled in the center portion of the frame 18.

The rear end of the shaft 22 is provided with a bearing 23, which is hung in a U- shape frame 24: secured to the underside of a collar 25 centrally mounted upon the rod 14. The bearing 23 is adapted to undergo a limited upward displacement in the frame 24, and during such displacement is guided by the engagement of a pair of laterally projecting pins 26 in vertical slots 27, formed in the frame 24 at each side thereof; Avertical coiled spring 28 is interposed between the bearing 23 and sleeve 25, tending to maintain the bearing 23 normally seated in the lower end of the frame 24. The journal forming end portions of the shaft 22 are round, but the remaining portion of the shaft is of square cross section (see Fig. 6), thereby adapting it to impart rotation to the chopping member which it carries with out restricting said member against sliding displacement on the shaft. The chopping member comprises a sliding hub 29, and a pair of spirally curved chopping bladesf30, held equidistant from the hub by spokes 31, each blade being extended through an are somewhat less than 180 degrees, and the two being disposed at opposite sides of the hub, so that their extremities are spaced both transversely of the cotton chopper and also longitudinally thereof. The chopping member furthermore includes a pair of diametrically opposite teeth 32 which project rigidly from the hub into the spaces between the blades 30. The hub 29 is formed with an annular groove, which receives a loose collar 33, from the sides of which a pair of pins 3% project laterally into vertical slots 35 formed in a yoke 36. The yoke 36 is hung upon the lower end of a substantially vertical lever 37 pivoted upon an arch bracket 38 rigidly extending longitudinally of the cotton chopper, the rear end of said. bracket being mounted fast upon the sleeve 25, and its forward-end fast upon the transverse portion of the frame 18. By swinging said lever forward or back about its pivot, the chopping member will be subjected tov a slight displacement upon the correlated shaft. With said lever there is correlated the usual means for holding the lever adjusted in various positions of angular dis placement.

, The structural features of my invention having been above fully described, the operation of thesame will now be explained. My cotton chopper is to travel along a row of cotton straddling the same, and rotation will be communicated to the shaft 19 and chopping member from the small wheels 20. Each blade of the chopping member as it cuts across a row will remove a number of plants leaving a space. As the adjacent extremities of the chopping blade cut across the row, the space between said blade will cause a number of plants in the row to be left standing producing a hill. The teeth 31 cutting centrally through the hill will loosen up the earth without uprooting the plants. By swinging the lever 37 the operator can cause the chopping member to dodge any desired plant which it may be approaching, so that where the growth is sparse, the size of the hill may be somewhat increased. In case the chopping member encounters an. obstacle in the row or some slight rise in the ground, the rear end of the shaft 19 will undergo a certain upward displacement compressing the spring 28, and said spring will return the rear end of the shaft to its normal. position after the obstacle or elevation has been. surmounted.

The invention is. presented as including all such modifications and changes as properly come within the scope of the following claim:

'VVhat I claimis:

A cotton chopper comprising an arched axle, transporting wheels mounted upon the extremities thereof, a tongue rigidly connected with said axle and spaced in front thereof, an arch bar depending. from the tongue and having transverse relation with the tongue, a pair of beams. extending rearwardly from the extremities of the arch bar, a member rigidly connecting the lower portions of the arch bar, an arm rigidly depending from said member, a horizontally disposed U-shaped wheeled frame spaced rearwardly from said arm and connected with the lower end thereof, a member rigidly connecting the rear. end portions of said beams, a shaft parallel to. said beams having its rear end supported by said member and its forward end supported by the U- shaped frame, means. communicating rotation to said shaft from the wheels of the. U- shaped frame, and a cotton chopping member mounted upon said shaft.

In testimony whereof I have signed my name to this specification in the presencev of two subscribing witnesses.
