COTTON-STALK PU LLER.

SPECIFICATION forming part of Letters Patent No. 238,825, dated. March 15, 1881.

Application filed April 10, 1880.

To all whom it may concern:

Be it known that I, JOHN 0. WILSON, of Cameron, in the county of Milam and State of Texas, have invented certain new and useful Improvements in Cotton-Stalk Pullers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a top view. Fig. 2 is afront view. Fig. 3 is a longitudinal sectional view; and Fig. 4 is a detail view, in perspective, of the stalk-pulling mechanism.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to an improved ma chine for pulling cotton-stalks, the construction of which will be hereinafter more fully described, and particularly pointed out in the claim. I

In the drawings hereto annexed,A represents a rectangular frame mounted upon an axle, B, supported upon wheels 0 0, one of which, for convenience in turning, is loose, while the other is fixed upon the axle. The latter, which between the side pieces of the frame is square'in cross-section, revolves in suitable boxes or bearings upon the under side of the frame.

Upon the axle, within the frame,is secured a wheel or disk, D, of slightly less diameter than the transporting-wheels.

Upon each of the four sides of the axle, closely adjoining the disk D, is pivoted a rod, E, carrying at its end a block, F, flat upon its inner side, (adjoining the disk,) but beveled upon its outer side, as shown. Said blocks should reach nearly or quite to the periphery of the disk D. Check-plates G are provided upon the axle for the purpose of preventing the rods E from swinging too far away from (No model.)

A cross-piece, J, secured above the axle upon uprights K, rising from the sides of the frame, carries a downward-projecting stiff spring, L, the lower end of which is beveled or curved in a forward direction, so as to engage the beveled blocks F and force them against the face of wheel D, between which and the said blocks F the cottonstalks are thus clamped and held securely while being pulled out of the ground by the continued rotary motion of the disk D.

A suitable wheel or drum, M, upon the side of disk D, or upon the axle, is connected by a band or belt, N, with a shaft, 0, mounted in suitable bearingsin the rear of the axle. The

said shaft, to which a rotary motion is thus A pulling-wheel having radial jaws that are opened and closed by cam devices has been heretofore used in stalk-pullers, and is not broadly claimed herein.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States The cotton-stalk puller consisting of the frame A and axle B, having rotating disk D, the rods E, carrying the blocks F,-th e checkplate G, secured to the axle to prevent the rods E from being disengaged from the disk, the beveled guides I H, and the guide L, attached to the cross-piece J, the lower end of which is beveled to engage the blocks, whereby they are forced against the disk, as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN 0. WILSON.
