COTTON-(SHOPPER.

SPECIFICATION forming part of Letters Patent No. 463,232, dated November 17, 1891.

Application tiled J'uly 2, 1891. Serial No. 393.259. (No model.)

T0 all whom it may concern.-

lle it known that l, J AMES M. LANKFORD, a citizen of the United States of America, residing at Eufaula, Creek Nation, Indian Territory, 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 saine, reference being had to the accompanying drawin gs, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to cotton or cane cultivators; and it has for its object to combine therewith chopping and scraping devices with a View to saving labor.

The invention consists in structural features and combinations of parts, as will now be fully described, reference being had to the accompanying drawings, in which- Figure lis aperspective view of a cultivator Figs. 2 and 3 are respectively a front and rear elevation, and Fig. 4 a detail top plan View, of the main frame of the machine.

Similar symbols indicate like parts wher ever such may occur in the above-described figures of drawings.

F indicates the main frame, and consists of v the axle portion f, that has at one end a short axle f for one of the carrying-wheels XV and at thc opposite end a longer axle f2 for the other carrying-wheel lV', whose hub w on the inner side of the wheel is extended and terminates in a circular flange wz, to which is secured a bevelwheel w, which latter, if den sired, may form an integral part of the hub w. From the axle portion of the frame F projects the longitudinal girt F and from near the forward end of the latter a cross gilt or arm F2. The forward end of the longitudinal girt F of the frame F is supported from a caster or other suitable furrow-wheel W2,

and to saidl girt is secured a fender or shield F5, that is adjustable vertically by means of a thumb-nut f3, working on a bolt f4, that projects through a slot f5 in the fender, which is arranged to-one side of the choppers here-s inafter to be described, so that when the ma chine is at work the chopper-shaft revolves from the fender, the plants chopped by the choppers being thrown against the fender into the furrow, instead of being. scattered over the field. `From the axle portion f of the frame projects a forwardly-inclined arm A,A

that supports the adjusting mechanism, as well as the operative devices, when. elevated above the ground. The frame F, constructed as described,may be of any desired or appro priate material, and, if desired, the entire frame may be made of metal and cast in one piece. B. B are braces, that brace the axle portion f and the arm F2 tothe longitudinal girt, and FJL is a foot-rest for the driver when on his seat S', which latter is secured to the axle portion f of the frame, the said foot-rest serving also as a brace for the overhanging or forwardly-inclined standard or arm A, to which vone end of said foot-rest is secured,the other being secured to the longitudinal girt F. In the Yaxle portion f of the frame is formed a bearing for the rear end of the longitudinal shaft S, whose forward end revolvesin a hearing B, that is connected by a chain or rod b to the outer end of a lever L, fulcrumed in the overhanging arm, said lever being provided with the usual lockingpawl P, adapted to engage notches or teeth in the surface of a sector s, secured to the said varm A, and by means of which lever L the shaft S is adjusted vertically, said shaft carrying the choppers (J, of any usual or preferred construction. The bearing B for the forward end of the shaft S is fitted and guided in a vertical slot formed in the cross-l1ead f, formed at the outer end of the cross-girt or laterally-projecting arm Fi, on the face of which crosshead f6 are formed or secured the bearings for the pivots or journals p of the tongue or shaft T. At its rear end the shaft S carries a bevel-wheel w3, that meshes with the like wheel w on the hub w of the carrying-wheel NV', and whereby said shaft S, and with it the choppers, is re volved.

To the frontend of the shaft S, that p'ro jects sufticiently from the bearing B are se cured a pair of Scrapers S2, arranged to straddle the row; but, if desired, a pair of straddlerow cultivator teeth or plows may be substituted instead of scrapers, according to the nature of the work to be performed by the IOO machine, so that both the scrapers and choppers can be simultaneously adj usted relatively to the land by one and the sameleverL.

To the aXle portion fare pivoted a pair of straddle-row cultivators C C', which are connected by a chain or rod R to a hand-lever L', that, like lever L, is fulcrumed to the arm A and provided with the usual locking-pawl P', adapted to engage notches or teeth on the surface of a sector s. Both levers are shown as being Within easy reach of the driver when on his seat. Those familiar With machines of the class to which my invention pertains will readily comprehend not only the advantages, but also the operation, of my said machine, and a further description of such advantages and operation Will therefore not be necessary here.

In practice, and as is usual, I secure to the longitudinal girt F a tool-box BX, as shown.

Having now particularly described my invention,what I claim, and desire to secure by Letters Patent, is-

'l. In a .machine of the class described, a revoluble and vertically-adjustable choppershaft, in combination with a vertically-adjustable fender on one side of the choppers of said shaft, for the purpose set forth.

2. In a machine of the class described, the main frame consisting of the longitudinal girt F', a furrow-Wheel at the forward end of said a short axle at one end and a long axle at the.

other, and said girt F2 terminating in a vertically-slotted cross-head, in combination with the drive-Wheels I and IV on the short and long axles, respectively, the bevel-wheel w, connected with said Wheel W the choppershaft S, having its bearings in said cross-head and the cross-gilt f, and the bevel-Wheel w3 in gear With said bevel-Wheel w,`for the purpose set forth.

3. In a machine of the class described, the combination, with the chopper-shaft S, the Scrapers mounted thereon, the straddle-row cultivator C, and the main frame, having Wheel-axle portion f, to which said cultivators are pivoted, and a forwardly-inclined standard or arm A, of the sectors s and s', the levers L and L', supported by said arm A, and connections between the levers, the shaft S, and the cultivators C, for the purpose set forth.

In witness whereof I have hereunto set my hand in the presence of two 4attesting witnesses.

JAMES M. LANKFORD.
