IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 36,999, dated November 25, 1862.

Io all whom it may concern:

Be it known that I, WILLIAM J oNEs, ot'Wilson,in the county of Winona and State of Minnesota,have invented a new andimproved Plow; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of my invention; Fig. 2, a plan or top view of the same; Fig. 3, a horizontal section of the same, taken in the line :0 00,.Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a plow-beam, and B B handles attached thereto. The beam and handles may be constructed in the'nsual way, and therefore do not require a minute description.

0 0 represent two mold-boards, which are permanently connected back to back. Each mold-board is provided with a share, as usual, and also provided with a landside, D, the latter, like the mold-boards, being connected together at their back ends,as shown at a in Fig. 1. The landsides have each a standard, E, attached to them, of slightly curved form, and to each standard a colter, F, is secured,thelower ends of which are connected with the shares of the mold-boards. The back parts of themoldboards have also a short standard, G, attached to them, the upper end of which, as well as the upper ends of the standards E E, are secured to a semicircular plate, H, which is shown clearly in Figs. 2 and 3. The plate H is connected near its ends by a straight bar or plate, I, as shown in Fig. 3, and this plate I is connected at its center to the under side of the beam A by a pivot-bolt, b. The semicircular plate H is fitted within a guide-plate, J attached to the under side of the beam A, said guide-plate being formed by bending or curving the ends of the plate J in hook form, so that they may fit or catch under the sides of the semicircular plate H, as shown clearly in Fig. 1.

Near each end of the semicircular plate H there is made a hole, 0. These holes are at op positesides of the pivot-bolt I), and at equal distances therefrom. These holes receive a pin, (1, which is attached to the front end of a lever, K, on the upper surface of the beam A, said lever having a spring, L,. attached to its back end behindits fulcrumpin e, which spring has a tendency to keep the pin (1 in the front hole cof the plate H, as will be fully understood by referring to Fig. 1. The pin d prevents the mold-boards from turning, keeping them in a proper working position when'at either side of the beam A.

It will be seen that by depressing the back part of the lever K, and thereby raising the pin (1 clear from the plate H, the latter may be turned, and consequently the mold-boardsG O, to either side of the beam A, and a right or left hand plow obtained, as occasion may require.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination of the mold-boards O C, shares F F, landsides D D, and standards E E G, with the plate H, guide-plate J, lever K, and beam A, all in the manner herein shown and described.

WM. JONES.
