REVERSIBLE PLOW.

BPFICIE'ICATION forming part of Letters Patent No. 324,109, dated August 11, 1885.

Application filed June 2. 1885. (No model.)

T0 to whom it may concern.-

Be it known that I, WILLIAM COALMAN HAULBRooK, of Homer, in the county of Banks and State of Georgia, have invented certain new and useful Improvements in Reversible Plows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure l is a side elevation of the beam, standards, and handles of one of my improved reversible plows. Fig. 2 is a plan view of the same, partly in section, through the line 00 ac, Fig. 1. Fig. 3 is a rear elevation of the same.

The object of this invention is to provide plows constructed in such a manner that they can be readily reversed, and which will be firm and steady when in use.

The invention consists in the construction and combination of various parts of the plow, as will be hereinafter fully described, and then pointed out in the claims.

A represents the plow-beam, in the rear end of which is formed a vertical V-shaped recess, 13, into which fits the V-shaped forward end of the block 0. The lower ends of the handles D are attached to the opposite sides of the block 0, and their upper parts are connected by a round,,E.

F is a rod, which passes longitudinally through the center of the handle-block G, is screwed into or otherwise secured to the rear end of the beam A, and has a cross-head, G, formed upon or attached to its outer end. The rear end of the handle-block O is beveled in line with the rear edges of the handles D, and against it rests the forward side of the wedge H,which has a slot, I, formed through it for the passage of the rod F.

The wedge H is made of or faced with metal to prevent wear, and has L-flanges J upon the forward edges of its sides to overlap the side edges of the plate K, attached to the rear end of the handle-block O to prevent wear, so that the wedge H cannot turn upon the rear end of the handle-block O,while being free to slide up and down upon it. Upon the rod F, at the inner side of the rear facing-plate of the wedge H, is secured a nut, R, to keep the said wedge close to the cross-head, G, so that the down ward movement of the wedge will draw the beveled forward end of the handle-block 0 out of the recess B in the rear end of the plowbeam A, and thus allow the said beam to turn freely. Upon the upper end of the wedge H is formed or to it is attached an arm, L, the upper end of which is pivoted to a lever, M. The lever M is pivoted at one end to one of the handles D, and its other end projects a little beyond the other handle, so that it can be conveniently grasped and operated to raise and lower the wedge H. The free end of the lever M moves along a catch-plate, N, attached to the handle D, so that it will be held securely in any position into which it may be adjusted.

To the opposite sides of the rear part of the beam A are attached plow-standards O,which project in opposite directions, and one of which is designed to receive a right-turn plow, and the other a left-turn plow, or one may re ceive a turn-plow, and the other a subsoilplow, as may be desired.

The standards 0 can be secured to the beam A by bolts or rivets P passing through them and through the beam A near its edges, and the bolts Q passing through them and resting against the edges of the beam, as shown in Figs. 1 and 2. Several holes are formed through the end parts of the standards 0 to receive the bots Q, so that the pitch of the plows can be readily regulated.

With this construction when the plows are to be reversed, the plowman presses the free end of the lever M downward, which lowers the wedge H and releases the handle-block, so that the plows can be reversed by swinging the beam A to one side by means of the handles. As the plow-beam comes into place the plowman raises the free end of the lever M, which draws the wedge H upward and causes the beveled or V-shaped forward end of the handle-block O to enter the V-shaped recess B and thus bring the beam Aand the handleblock 0 exactly into their proper relative positions and holds them firmlyin place, so that there can be no shaking of the parts of the plow when the said plow is in use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-=- 1. In a reversible plow, the combination,

with the plow-beam A, having V-shaped recess B, and the block 0, having V-shaped forward end and beveled rear end and provided with handles, of the rod F, having a cross- 5 head upon its outer end, the wedge H, slotted for the passage of the rod F, and the arm, lever, and catchbar L M N, substantially as herein shown and described,whereby the said beam can be readily locked in place and re- 10 leased, as set forth.

2. In a reversible plow, the combination, with the handlebloek 0, having beveled rear end, the rod F, passing through the said block \VILLIAM C. HAULBROOK.
