FRANK A. HILL, OF SAN LEANDRO, CALIFORNIA.

SIDE-HILL PLOW.

SPECIFICATION forming part of Letters Patent No. 212,320, dated May 31,1881. Application filed October 18, 1880. (Model) To all whom it may concern:

Be it known that I, FRANK A. HILL, ofSan Leandro, in the county of Alameda and State of California, have invented a new and useful Improvement in Side-Hill Flows; and I do herebydeclare that the following is a full, clear, and exact description of the same.

My invention relates to plows, the firstpart more particularly to sulky-plows, whereby they are adapted to operate more effectually on hillside work, the second part to the mode of connecting the plowshare to the plow.

In the drawings hereunto attached and forming part of this specification, Figure 1 is a side elevation of the plow, with the right-hand wheel shown in dotted lines. Fig. 2 is a plan view, showing the axle and the mode of connecting the plows thereto, together with the devices for changing the position of the plows in relation to the axle. Fig. 3 is an elevation of the landside of the plow itself, and Fig. 4 shows the re-enforcement for the landside in plan and side elevation. Fig. 5 is a bottom .view of the plow.

The form of plow shown in the drawings (in main features old) is provided with wheels capable of elevation or depression in relation to the axle, so that the relative heights of the wheels may be changed to adapt the plow to any ordinary slope of hill. The devices by which the wheels are thus connected form no part of the invention, and need not be particularly described.

The main axle A is straight and supports the two plow-beams B B. These beams are firmly connected to each other by the transverse bars a I) and brace c. The tongue of the sulky is bolted to the transverse bar a, and runs back under the axle and is connected to the center of the cross-bar b. The two plow-beams are thereby firmly connected to each other and to the tongue independently of the axle. They are connected to the axle at one point by a pivotal bolt, 6. This bolt passes through a piece of angle-iron fixed upon the plow-beam B and through the axle, so that the axle may have an independent horizontal movement on said pivot in relation to the plow-beam. This enables the driver to turn the wheels slightly oblique to the direction of the draft, and thus to counteract the tendency on the part of the plows to work downhill. The amount of deilection of the wheel will depend upon the steepness of thehill. Under any circumstances a play of only a few inches is required for the axle to accomplish the purpose desired.

The free end of the axle is held to the plowbeam B by means of a strap, f, secured to the plow-beam and forming a slot, g, in which the axle is free to move back and forth. Any convenient means may be used for moving the axle and holding it in place. The devices shown in Fig. 1 are specially well adapted for the purpose. This device consists of a lever, h, provided with a locking-segment with ordinary locking devices, and a connecting-rod, k, pivoted to the lower end of the lever and to the rear of the axle outside of the plow-beam. The lever h is pivoted upon the plow-beam B at a suitable distance in rear of the drivers seatto enable him to conveniently grasp it. The driver can thus at any time change the inclination of the wheels, and crowd the plows more or less uphill, as he may find it necessary.

The second part ofin y invention is shown more clearly in Figs. 3 and 5. In these'figures the forward part of the landside, which receives the point, and that part of the plowshare connected therewith, is formed with a recess, z, having inclined sides. The rear side, 00, is undercut, and in the same plane as the line of junction 3 3 of the two parts of the share. The forward edge of the recess is parallel with the The land side at of the detached portion is formed with a corresponding projection, a, and depression 0, the latter fitting the raised portion 12 in front of the recess heretofore de scribed. The parts, when put together, snugly interlock and are held by bolts 1 2 3, the construction affording greatly-increased security in the connection.

It is not material that the plowshare be made in two parts or be divided in the manner shown in order to secure the advantages of this mode of locking.

In order that the lower edge of the landside, which is liable to be worn out first, may be easily and cheaply renewed, I have cut this part away and provided a piece, q, formed preferably of hardened steel, which is attached to the landside in such a manner that it may be easily removed and replaced. This device is shown in Figs. 3 and 4. The piece is formed with ears 6 and 7, by means of which it is securely bolted in place,

I am aware that plows have been made with various forms of pivotal connection between the plow-beams and axles, in order to give a lateral adjustment to the wheels, and Imake 11o broad claim to devices of this character, but only to the specific construction whereby my device differs from those shown in patents already granted.

Having thus described my invention, what I claim is- 1. In combination, the beams B B, crosspieces ab, connected to the tongue, the whole forming the frame which supports the plows,
