ROTARY CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 239,219, dated March 22, 1881.

Application filed January 5, 1880.

To all whom it may concern Be it known that I, JAMES W. BODLEY, a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Itotary Cultivators; and Ido 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 bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of cultivators in which rotary concav o-convex disks are employed in working the soil around sugar-cane, tobacco, and other like plants; and it consists, first, in the improved construction of the devices for adjusting and securing the rotary disks; and, further, in the construction of the draft-bar andits manner of attachment, as fully hereinafter explained.

In the drawings, Figure l is a rear view of the cultivator; Fig. 2, a top view; Fig. 3, a front view; Fig. 4, a side view; Fig. 5, a detail sectional view.

Like letters of reference refer to like parts.

A and B are cross-beams, permanently secured to a central beam, F, running lengthwise of the machine. These three beams form the frame of the cultivator, to which the various working parts and their connections are attached. 0 O are connecting frame-rods. h h are braces. The beam F extends forward and forms the tongue in front, and in the rear it is provided with handles a a, for the operator to guide the machine. The beams B and A are provided with oblong slots 1) b and c 0, near their ends, to receive adjustable clamps connected with the standards and braces which secure the rotary plows in position.

0 is a vertical standard, made preferably of Wrought-iron or steel, in one continuous piece,

screw-threaded at its upper end, and provided with a collar at d, and extending through the slot in the beam B, and adjustably secured to the same by means of a crank-handle nut, e. The lower end of this standard is turned at right angles inwardly, and formed into an axle, f, upon which the rotary disks D D revolve. The end of the axle extending through the diskis provided with a cross-hole at g, and a cap or washer, h, with corresponding holes through its side, through which passes the end of a brace-rod, I, and is secured thereto by means of a screw-threaded nut. The brace I extends from the end of the axle forward to the beam A, and is secured to an adjustable clamp, 5, working in the slot 0. This holdfast z is a screw-threaded bolt, flattened at one end, with a hole in it,-and provided with crankhandle-nuts e e to hold the same in position.

K is a brace, which is attached to a washer,

k, on the axle, 'on the opposite side of the rotary disk, and extends forward, and is fastened to the hold-fast i by means of a bolt.

L is a side brace, secured to the beam B in the same manner as the standard 0, and is attached to the side of the latter by means of a strap, Z, around the standard, and bolted to the brace L.

'M is a hand-lever, fulcrumed on a spindle, M, which is secured by means of a strap-connection, Z, around the standard G, and bolted to the brace L at a point just above the axle. 5

E is a broad-faced traction-wheel, attached to the end of the lever M, not unlike the manner of attaching a wagon-wheel to its axle. When it is desirable to raise the rotary plows from contact with the ground the lever M is secured in an upright position by means of a pin or spring-snap, or other suitable fastening, as shown in Fig. 4, throwing the weight of the machine on the traction-wheels. When it is required to use the plows the lever M is placed in the position shown by the dotted lines in Fig. at, which nearly balances the wheels and keeps them off the ground while the plows are in use.

G is a draft-rod connected at one end with a washer, It, on the axle at f, and held in a horizontal position at the other end by a chain,

H, fastened to the beam A. This chain-connetion allows the draft-rod to accommodate itself to the line of draft, and thus avoids the 9 5 liability of breakage usual where rigid draftbar connections are used.

it n are whiftletrees.

When required to change the inclination of the rotary cutters to the line of draft it is readily done by loosening the nut e on the standard 0, which permits the standard and axle to turn at any required angle, and by moving the clamp i in the slot in the beam A, the rotary wheel is held securely in position by means of the braces I and K. The adjustment of the plows in relation to each other, as to distance apart, is accomplished in the same manner by means of the movable clamp i and crank-nuts e c, which permits the plows to be moved to and from each other.

Havingdescribed my invention ,what I claim and desire to secure by Letters Patent, is

1. In combination, the standard 0, adjustably held in the slot-ted beam B, and capable of rotary motion, the disks D, secured upon an axle formed by bending such standards 0 at right angles, the parallel beam A, having the slots 0, and connecting-braces secured to JAMES W. BODLEY.
