MATHEV H. GARVOOD, OF SOUTH BEND, INDIANA.

WH EEL-PLow.

SPECIFICATION forming part Of Letters Patent No. 438,539, dated October 14, 1890.

Application filed July 9, 1890. Serial No. 358,168. (No model.)

lowingis a full, clear, and exact description' thereof, reference 'being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- 'Figure 1 is a plan view of ariding or wheelv plow, showing myiinprovements. Fig. 2 is a side view in detail of the saine. Fig. 3 is a detail sectional view through the parts ernbodying my invention.

This invention relates to riding or wheel plows, and is an improvement on the plow for which Letters Patent of the United States No. 398,961 were granted on the 5th day of March, 1889, and it has especial reference to the furrow-wheel and its mountings on the frame, as will be clearly understood from the following description and claim.

Referring to the drawings by letters, A designates the beam of an ordinary plow.

B designates a frame, roughly rectangular in contour and formed of metal, lying parallel with and above the beam, and the beam is connected by shackles to a cranked shaft C, mounted in bearings transversely of the frame. The frame is supported upon an adjustable wheel D at the land side of the plow, a rear caster-wheel E, and on the furrow side by an adjustable wheel H, hereinafter referred to. These parts are or may be, with the exception of wheel H and its mountings, constructed and arranged substantially as shown in the patent above referred to. At the front end and furrow side of frame B is attached acasting F, which is formed with tubular :portions f f, through which pass the upper horizontal portions of a cranked shaft G, which is retained in position and kept from longitudinal play through portions f by a crank-arm g, which is slipped on the shaft between portions f f and secured by a setscrew I.

The shaft bends at right angles to the portions f f at the outside of the frame, and its lower end is bent outward again at right angles, and on this end is mounted a furrowwheel H, about similar in construction to wheel D. Arm g is connected by a rod K with a lever k, pivoted on the side of the frame near the drivers seat and provided with a handdatch engaging a sector J on the frame. By turning shaft G in its bearings in casting F the wheel H will be raised or lowered, as is evident. By loosening screw I the shaft G can be shifted in its bearings in casting F, and thus set wheel H closer to or farther from the frame. It will be observed that this wheel H is at the furrow side of the plow and will run in the furrow previously made. It does not have any lateral movement or oscillation, but constantly revolves in a plane parallel with the plow-beam, and the beam is not affected by the rising or falling of the furrow-wheel or frame in passing over small obstructions. The width of the furrow is regulated by the adjustment of wheel H toward or from the frame. The vplow being suspended from the cranked shaft in a nearly-balanced condition can be suspended from the frame clear of the ground and transported. In turning, the plow-Wheel H is raised by shifting shaft G until it is out of the furrow and clear of the ground and so held until the turn is completed. Itis then lowered to working position. By this wheel the frame can be so supported thatAt-he plow will cut either deep or shallow. In/making the first furrow the wheel is set to run on top of the ground while the plow cuts a furrow, and on the next round of the plow the wheel is lowered into the furrowv and adjusted to cause the plow to cut a furrow of desired width and depth.

In the patent referred to there is a casterwheel employed at the furrow side, and this not only prevents regulating the width of the furrows thereby, but makes them uneven or undulating, as the caster can swing to one side and revolve at angles to the beam.

In a riding-plow, a frame B, a plow-beam A, loosely connected and suspended therefrom by a cranked axle C, and the wheel D on said axle, in combination with a casting F, secured to the front furrow-side corner of the IOD frame and having tubulzu'portonsff, a crankshaft G, jonrnaled in said portions f, the arm g, adjustably fixed on the shaft between portions ff, the level' 7.5, rod K, and sector J, fol1 oscillating' and adjusting shaft G and Jche fu 1- row-Wheel thereon, substantially as and 'for the purpose set fol-th.

In testimony that; I Claim the foregoing as my own I affix my signature in presence of two Witnesses.

MATHEVV H. GARWOOD.
