IVILLIAM B. SMITH, OF ATLANTA, GEORGIA.

COTTON-HOE.

SPECIFICATION forming part of Letters Patent No. 461,133, dated October 13, 1891.

Application filed March 20, 1891. Serial No. 385,740. (No model.)

To @ZZ whom t may concern.'

Se it known that I, WILLIAM B. SMITH, of Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Improvement in Cotton-Hoes, of which the following is a specification.

Myinvention relates to an improvement in cottoirhoes in which a disk-fender acting as a traction-wheel actuates a thinner or cut-ter transversely to the row or path in which the plow travels, the traction-disk and thinner or cutter forming an attachment for plows of ordinary structure.

A practical embodiment of my invention is presented in the accompanying drawings, in Which- Figure I is a view of the plow in side elevation with the attachment secured thereto as in use. 2 is a top plan View of the same. Fig. 3 is a horizontal section through line xx of Fig. l. Fig. I is an enlarged sectional View of the joint at the plow-beam. Fig. 5 is a view in detail of one form of thinning or cutting disk, and Fig. 6 is a view in detail of another form of thinning or cutting disk.

A represents a plow-beam, to which a ploW c, of any ordinary or desired form, may be attached.

To one side of the beam A one member B of the attachment connection is secured and is provided on its lower face With a rounded projection b, adapted to seat in the concave face b of the other member B of the connection. The lower face of the member B is provided with a recess b2 for the reception of the upper end of the hanger C, to which the operatin g parts of the attachment are secured. The faces of the projection b and seat b are roughened to prevent slipping, and a bolt extending through the hanger C and the members B and B serves to lock the parts in the desired adjustment. It is obvious that the concave seat might be made in the member I3 and the rounded projection on the member I3.

The combined traction disk and fenderI) is made dislrshaped, and is int-ended to present its convex side toward the row when in operation. Its edge is notched toafford it a better hold upon the earth in proximity to the row, and it is provided upon its outer face with an annular series of teeth d, adapted toengage and Arotate a pinion e,secured in a shaft E, as Will hereinafter be more particularly1 re ferred to.

The hub d of the traction-disk is provided with a taper bore adapted to fit a taper spindle F. The spindle F has a bore f extending longitudinally therethrough, and has a concave seatf on its inner end. The spindle is secured to the hanger by means of an L-shaped extension f2, formed integral with or fixed to the spindle at one end, and at its opposite end provided with an attachment precisely similar to that shown by the parts B B', the part corresponding to B being provided with a recess f3, in which the lower end of the hanger is secured.

A horizontattframe G, having a general U- shaped form, extends from the inner end of the spindle around the edge'of the tractiondisk and back to the outer end of the spindle. The said frame G is provided at the inner end of the spindle with a rounded projection g, adapted to engage the concave seat f in the end of the spindle and is provided alongl its outer branch with a bearing gfor the reception of the operating-shaft E carrying the pinion c. The portion g2 of ,the frame G which extends from the bearing g to the outer end of the spindle preferably extends up and over the pinion e, as shown in Fig. I. The ends of the frame G are secured to the spindle and the traction-disk is secured on the spindle by means of a bolt II, which extends through the spindle and through both ends of the frame.

The direction of the shaft E is such that the cultivator-disk which it carries upon its rear end occupies a position substantially transverse to the row or the path in which the plow travels. The cultivator-disk may be either a series of arms '11 radiating froma hub I, as shown in Fig. 5, or it may consist of a curved blade c" extending partially around the periphery of the disk and secured to the hub I by arms i2, as shown iu Fig. G. In either case the disk is removably secured to a hub e fixed on the end of the shaft F., the adjacent faces of the hubs I I', and the hub e on the shaft being roughened or serrated to prevent slipping. The face of the hub e may be provided with screw-threaded studs disk either athinner or acutter, and the arms c 'L' or blade 7." will cut across the row at intervals, depending upon the number of arms i or the interval between the ends of the cutting-blade i. The latter having a cuttingedge on the front of its rim Will alternately cut With a shearing cut, and then skip as the plow advances.

What I claim is- 1. In a cotton-hoe, a traction-disk and means for attaching it to a plow or the like, a frame secured to and carried by the spindle of the traction-disk, and a cultivator-disk mounted in the frame and geared t0 the traction-disk, the cultivator-disk having a rotary movement in a plane transverse to the path of the traction-disk and having its cultivating-blade arranged to act at intervals, substantially as set forth.

2. In a cotton-hoe, the adjustable hanger, the adjustable frame and spindle secured to the hanger, the combined fender and traction disk mounted on the spindle and having an annular gear on its face, a shaft journaled in the frame and having a pinion adapted to gear with the annular gear, and a cultivatordisk removably secured to the shaft, substantially as set forth.

WILLIAM B'. SMITH.
