IMPROVEMENT IN SULKV-PLOWS.

Specification forming part of Letters Patent No. 118,563, dated August 29, 1871.

To all whom it may concern:

Be it known that I, JAMES L. VAN GORDER, of Sidney, in the county of Shelby and in the State of Ohio, have invented a new and useful Improvement in Sulky-Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specication, in which- Figure l represents a plan view. Fig. 2 is a side elevation, the wheels being removed to show more clearly the mechanisms by which the plow is manipulated. Fig. 3 is a section on line a. a of Fig. l, showing the parts by which the furrow-Wheel is lowered and raised and held in position. Fig. 4 is a rear elevation, partly in section. Fig. 5 is a side elevation of the mechanism for lifting the plow. L

The same letters of reference are employed in all the iigures in the designation of identical parts.

This invention, which is intended to improve the construction of sulky-plows, consists in the employment of an axle cranked in such a manner as to form a suitable space for the passage and vertical and lateral movements of the plowbeam, as well as a vertical part for the attachment of the plow-beam by means of an adjustable and jointed coupling. It further consists in novel combinations of devices for adjusting the axis of the furrow-wheehfor lifting the plow and holding it above the ground, and for adjusting the plow to take more or less land, all of which features will be generally explained in the following description and speciiicallypointed out in the claims.

The axle A carries at one end the unadjustable or land-wheel B, and its other extremity, which stands vertically, is provided on the outer side with a segmental plate, a, to the center of which the lever C is attached, turning upon a fulcrumpin, a. The short arm G1 of this lever has a projecting stud, C2, upon which the furrow-wheel D turns. By turning the' lever in one direction or the other the furrow-wheel is lowered or raised to throw the plowshare into any required position, a series of holes being' provided in the plate a for the purpose of holding the lever and the wheel in any desired position by means of a bolt which is passed through a hole in the lever and a corresponding hole of the series in the plate.

Other means for stationing the lever may be employed. The lever is also formed with a hook, c, folding over the edge of the segmental plate to steady it in its movements and hold it rmly to the plate. The axle is bent into adouble crank, as clearly illustrated in Fig. 4, to provide a vertical part, A1, for the attachment of the plowbeam, andV a suitable space upon each side of such vertical part to permit of the necessary movements of the plow-beam and the coupling bywhich it is attached to such part 5 at the same time the horizontal portion of the upper crank serves as a support of the seat A2. The plowbeam E is attached to the part Al of the axle by means of a coupling, composed of the plate F, which is at each end firmly secured to the side of the plow-beam in any suitable manner, and a clip, F which is pivoted to the side of the plate F, and constructed with two horizontal ears, f f 1, through apertures in which the part Al of the axle passes. This coupling permits of vertical as well as lateral motion of the plow-beam; and it also slides freely up and down on the part Al of the axle, on which it can be sustained at any required height, for deep or shallow plowing, by means of a transverse pin passed through one of a series of pin-holes formed in such part, as indicated in Fig. 4. The plow-beam is turned horizontally on the part A1 ofthe axle, to take more or less land with its share, by means of a lever, G, the short arm of which is linked by the rod G to the forward end of the beam. The lever may be controlled by a notched arc or in any other preferred manner. The draft .animals are hitched directly to the plow-beam, it being provided with a clevis for that purpose, while the tongue H serves simply as a means by which to guide the machine. The tongue is rigidly secured to the axle at different points by the stays h, h1, h2, and 7b3, as shown. The plow-beam is lifted to bring its share above the surface of the ground by means of a lever, I, which is pivoted on a standard or brace-bar, Il, and connected at one end by a rod, I2, to the part F of the coupling, and provided at the other end with a footpiece, I3, by which to operate it. This foot-piece is pivoted, by means of downwardly-projecting ears i, upon a lateral stud of the lever, and its upwardly-projecting ear i is linked by a rod, K, to the latch K. This latter is hung upon the fulcrum-pin of the lever I, and is so disposed that as the plow-beam is lifted the necessary distance by turning the foot-piece on its stud so as to throw the lower end of the latch to the rear, its notch will hook under a projecting part of the part F of the coupling and sustain the plow-beam in its elevated position. The coup ling is released from the latch by oscillating the foot-piece forward.

What I claim as my invention, and desire to secure by Letters Patent, is

I. The combination of the cranked axle A A1, the coupling F F or its equivalent, lever I, and the plow-beam with plow attached,substantially Y:asf described'.
