COTTON-SHOPPER.

SPECIFICATION forming part of Letters Patent No. 452,093, dated May 12, 1891.

Application iiled January 26, 1891.

To all whom, it may concern:

Be it known that I, NE1L JEFFERSON BAG- GETT, a citizen of the United States, residing at Gunsight, in the county of Stephens and State of Texas, have invented certain new and 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.

My invention relates to a cotton-chopper; and the object of my invention is to provide a machine that is simple in construction and thoroughly effective in operation. I attain said object by a certain construction, combination, and arrangement of parts fully described in this specification and illust-rated in the accompanying drawings, in Which- Figure l is a front view of the invention. Fig. 2 is a plan view of the same. Fig. 3 is aA perspective view of the axle and adjustable frame and chopper detached from the wh eels. Fig. 4t is a detailed view of the saddle and crank-shaft.

Referring to the drawings, the letter A designates the axle, which is constructed with the slots or reduced portions a upon each side and in the center of same. Said slots are adapted to receive the adjustable stapleshaped frame or saddle B. It will be observed that the transverse bar or rod C passes through t the top of this frame and projects upon each side through the slots d d in the top of the choppersD D ,thereby holding said choppers securely in their normal positions and at the same time allowing them a free vertical movement. In the lower ends of the staple-shaped frame or saddle B` there are the slots b, having the transverse bolts h', which afford a bearing for the crank-shaft E. The ends of the crankshaftE are rigidly secured near the shank to the front and rear portions of the choppers D and D respectively, by means of the screweyebolts F. These screw-eyebolts maybe located in any part of the slotf of the choppers D and D', accordingly as it is desired to regulate the depth of the chopping. WVhen shallow chopping is needed the screW-eyebolts F are placed in the topmost portion of the slot f, and vice versa when it is desired to have the plates G of the choppers penetrate deeply.

Serial No. 379,077. (No model.)

Upon the front or rear portions of the crankshaft E there is located and rigidly secured a sprocket-wheel H, which drives the crankshaft E. It is easily seen that the stapleshaped frame B, to which is attached the choppers D and D', can be easily removed or detached from the axle A simply by removing the bolts b and raising the same vertically from off said axle.

I represents the n-shaped frame, which is secured horizontally across the axle A by means of a T-shaped screw-bolt t', which is located in a longitudinal slot in the axle A. In the lower ends of said framel there are suitable bearings?, in which is located the shaft J, having upon each end the pinion K. Upon the shaft J there is also located a'sprocketwheel Lf A M indicates a crown-wheel, which is rigidly attached to one of the ground-wheels N of the machine.

O is a sprocket-chain that connects the sprocket-wheels II and L, respectively.

The machine may be readily thrown out of gear simply by loosening the T-shaped screwbolt t and slipping the n-shaped frame toward the center of the axle A and then tightening said bolt.

P is a guard to protect the end of the rod C, and serves as a support for the handle R in raising the choppers D D.

S is a tension-wheel for tightening the sprocket H.

It is well to mention the fact that the mechanism of my chopper, as herein described, can

be applied to almost any two-wheeled cultivator by making a few slight alterations, which will readily suggest themselves to any person of ordinary mechanical skill.

The operation of my machine is as follows: rlhe wheels N impart motion to the crownwheel M, which in tu rn communicates motion to the pinions K of the shaft J, which drives the sprocket-wheels H and L. The sprocketwheel II imparts motion to the crank-shaft E, which drives the vertical choppers.

As it is apparent that my invention is both useful and practical, I deem it useless to further enlarge upon its merits.

- W'hat I claim isl. In a cotton chopper or cultivator, the

axle mounted upon suitable ground-Wheels,

IOO

in combination with a crown-wheel rigidly secured to one of said ground-wheels, the 11- shaped frame secured horizontally across the axle near the inner side of one of the groundwheels, the shaft J, having hearings in the lower ends of said frame and provided with pinions and sprocket-wheel L, the adjustable staple-shaped frame or saddle fitting over the center axle of the machine, the transverse bar passing through the top of this frame and projecting through the slots in the top of the choppers D and D', the crank-shaft E, having hearingsin the lower end of said staple-shaped frame and having its ends located in the screweyebolts upon the front and rear side of the choppers D and D', the sprocket-wheel Il, rigidly secured upon said crank-shaft, the vertical choppers D and D', operated by the crankshaft E, and the sproeket-chain connecting the sprocket-wheels ll and L, all substantially as described, and for the purpose set forth.

i. In combination with the co-operating mechanism of a cultivator or cotton-chopper, the adj ustahle staple-shaped frame or saddle B, the transverse har C, passing through the top of this frame and the slots in the top of the choppers D and D', the crank-shaft E, having hearings in the lower end of the frame D and having its ends located in the screweyebolts upon the front and rear sides of the choppers D and D', the sprocket-wheel Il, rigidly seeured upon said crank-shaft, and the vertical choppers D and D', substantially as described, and for the purpose set forth.

In testimony whereof I affix mysignature in presence of two witnessesA NEIL JEFFERSON BAGGE'FI.

JOHN E. DAGGETT, A. J. DAGGETT.
