COTTONOHOPPER.

SPECIFICATION forming part of Letters Patent No. 467,915, dated February 2, 1892.

Application tiled September 25,1891. Serial No. 406,877. (No model.)

To a/ZZ whom, it may concern:

Be it known that we, HURNON K. OANSLER and'lHoMAs G.OANsLER,eitizensof theUnited States, residing at Itasca, in the county of llill and State of Texas, have invented a new and useful Cotton-Chopper, of which the following is a specification.

This invention relates to a cotton-chopper attachment for eultivators, the objects in view being to provide a cheap and simple attachment adapted to be applied to the ordinary sulky-cultivator frame, with little or no ehange to the latter, and when so applied to constitute an efficient machine for chopping and thinning cotton.

lVith the above objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referringr to the drawings, Figure l is a perspective of a eultivator-frame provided with a cotton-chopper attachment constructed in accordance .with our invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a detail in perspective of the attachment. Fig. 4 is a detail in perspective of thechoppingshaft.

Like numerals of reference indicate like parts in all the figures of the drawings.

l designates the axle of an ordinary sulkyeultivator, which axle, as is usual, is reduced at its ends and carries ordinary ground-wheels 2, to the inner end of the hub of one of which is secured a sprocket 3.

4t designates the usual draft beam or tongue, which is braced in this instance by means of the diagonally-disposed hounds 5, the front ends of which are bolted to the beam at opposite sides and the rear ends thereof to the front face of the axle at opposite sides of the beam. To the under side of the draft pole or beam a cross-bar 6 is secured, and from the same rearwardly extend the cultivator-beams 7, the ends of which terminate in shovels.

The foregoing describes the construction of an ordinary riding sulky-cultivator, and we will now proceed to describe the chopping and thinning attachment adapted to be used in connection therewith and constructed in aecordanee with my invention.

The attachment comprises a rectangular frame consisting of a cross-bar S, from the upper face of which rise hooks 9, inwardly disposed and adapted to removably engage and suspend the cross-bar 8 from the diverging hounds 5. From the under side of the cross-bar depend bearing-standards lO, terminating at their lower ends in bearing-eyes ll and supporting a rotatable driving-shaft l2. One end of the shaft extends beyonditsbearing-eye and carries a sprocket-wheell3, which is connected with and driven by a sprocketchain 14, leading from the sprocket 3 of the axle. Near one of its bearings there-is mounted on the shaft 12 a beveled pinion l5.

1G designates a U -shaped frame, the front ends of which terminate inl bearing hooks or eyes i7, which loosely engage the drive-shaft l2. A bea-ring 1S is mounted upon a transverse bar i9, that connects the sides of the frame, a-nd in said bearing a longitudinallydisposed shaft 2O is journaled. This shaft at its front end carries a beveled gear 21, which engages with and is driven by the beveled gear l5 of the drive-shaft, while at its rear end it terminates in one memberof a gimbalg joint 22. The rear cross-bar of the U- shaped frame is provided with an elongated loop or slot 23, and in the same a shaft 2i is mounted for rotation and for lateral movement. This shaft is but a continuation of the shaft 20, the two constituting a chopping-shaft, and like the shaft 2O it terminates in one member of the gimbal-joint. At its rear end it is further provided with the chopping-head 25, carrying chopping blades or cutters 26. A hanger 27 is bolted to the rear side of the axle, depends below the same, is bifureated, and has its bifurcations bent to form eyes 28 and receives the upper or T end of a T- bolt 29. The lower end of the T-bolt is provided with a head 30, and a curved lever 3l, having a loop 32, loosely receives said T-bolt, whereby the lever is swiveled thereon and is also fulcrulned on the hanger, said lever therefore being capable of both vertical and horizontal movements.

The end of the lever is bifurcated, and receives and has pivotedlthereto at 33 a curved depending connecting-rod 34:, terminating in a T- head 35. formed in the terminals of a collar 3G, "which This T- head engages openings IOC intervals, as the operator may desire.

collar loosely embraces the rear section of the cutter-shaft( It will be seen that motion imparted. from the ground-wheel to the sprocket 3 will be transferred by the chain 14 to the sprocket and shaft 13 and 12, respectively, and the latter by means of its pinion 15 will transfer the motion to the cutter-shaft and the cutter-head. B y swinging the hand-lever laterally the -chopping-head and its shaft will be also laterally moved, and thus may avoid any obstructionsuch as a stump, bowlder, dac-or cut only at By raising and lowering the lever the U-shaped frame and its parts are elevated above the ground, whereby the machine is inoperative. The lever may be locked in any of its vertical positions by a'toothed locking-bar 37, as will be obvious.

lt will be seen that the cotton-chopper constructed as described is of cheap, andy simple construction, under perfect control of the operator, may be raised Yand lowered into and out of operative position, and finally that the chopping-head may be caused to follow irregular rows, angles, &c.

Having described our invention, what we claim is- 1. The herein-described attachment for the purpose described, the same consisting of the cross-bar having a pair. of hooks for engaging diagonal braces` or hounds of a cultivator,

hangers depending from the cross-bary andv terminating in bearings, the drive-shaft journaled therein, gearing between the shaft and cultivator-wheel, an axle rotatably mounted in the frame and terminating ina choppinghead, a gear located at the front end of the chopping-shaft, and a gear engaging the same and located upon the drive-shaft, and a lever. for raising and lowering the frame and out` ters, substantially as specified..A

2. The combination, with the frame-work of the cultivator, the'drive-wheels, and the sprocket thereon, of the depending hangers, the drive-shaft journaled therein, the sprocket on the latter, the chain connectingthe sprocket with thatV of the axle, the U -shaped frame loosely hung on the drive-shaft Yand hav-ing bear-ings, the shaft mounted therein and terminating in a chopping -'head, the beveled gear mounted on the front end of said shaft, the companion gear mounted on the driveshaft, a lever fulcrumed on the frame-work,

and aI connecting-rod between the lever and chopping-shaft, substantially as specified.

3. The combination, with the frame-work of the cultivator, of the loosely-suspended U- shaped frame, the latter provided with a front stationary bearing and at itsvrear end with a transverse slot-,a shaft journaled in the front bearing, drive connections between the same and the cultivator, a shaft journaled in the slot and adapted for rotation and lateral movement and terminating at its rear end 1n a chopping-head, and a gimbal connection bei tween the inner ends of the shafts, substantially as specified.

4. The combination, with the .frame-Work of the cultivator, of the loosely-suspended U- shaped frame, the latter provided with a bearing, a laterally movable rotatable shaft mounted in the bearing and in a'slot in the rear end of the frame and carrying a cutterhead, drive connections between the shaft and the wheels of the cultivator, a hanger depend- Iing from the axle, a lever universallyconnected with the hanger, a collar on the shaft, and a connecting-rod loosely connected with the collar and pivoted to the lever, substantiallyV as specified.

5. The combination, with the framework l of the cultivator, ofthe loosely-suspended U- shaped frame, the latter provided witha bearing, a' laterally movable rotatablel shaft f mounted in the bearing. and in a slot in the rear end of the frame and carrying a cutterhead, drive connections between the shaft and f the wheels of the culltivator, a hanger depending from theaxle and terminating at its lower end i-n opposite eyes, a T-shaped bolt loosely connecting theV eyes and at its lower endV having a head', a lever located behind the axle and having. an eye loosely swiveled on the Witnesses: i
