IMPROVEMENT IN lPLOWS.

Specification forming part of Letters Patent No. 181,493, dated August 22,1876; application tiled l J une 3, 1876.

- ince of Ontario, in the Dominion of Canada,

have invented certain new and useful Improvements in Plows; and I do hereby declare that the following is a full, clear, and exact description ofthe same.

This invention relates to the construction of an iron plow, having the handles, beam, standard, and clevis-head integrallyof one piece of metal, the handles bifurcated from the beam, the share fitting into a triangular socket formed wholly in the end of the 'standard, and the land-side, with sole-plate affixed, pivoted to the standard at its front end, and at its rear portion provided with akeeper, adapting it to slide on an arm projecting downwardly from the'plow-beam, and adjustable vertically by a set-screw pivoted to the keeper, and working through a socket in the lateral portion ofthe arm.

Figure l is a front perspective of my plow, the mold-board removed. Fig. 2 is a top View of the same.

A is the beam, bifurcated at the rear to form the handles B B, and which, with the standard C for the share, the clevis-head P for the draft, and the projections D E, for securing the land-side and the mold-board, are formed inv tegrally of one piece of forged or cast metal. Centrally the beam is formed with a set-off, whereby the rearward portion of the beam will be inside t-heline'of draft of theland-side, so as to balance the plow and cause it to be easy of manipulation. The standard C curves forwardly, and its foot is formed with a triangular socket, F, to receive the shank of the share G. H is the land side, pivoted to near the foot of the standard, the rear part being held by a keeper, I, fixed thereto, and the projection D sliding therein. J is a setscrew in the projection D, and pivoted to the keeper I, so that by operating the 'screw the land-side can rearwardly be elevated or depressed vertically, to cause the plow to operate at a greater or less depth, according to the character of thel soil, or to the foreshortening of the share by wear. is the sole-plate, affixed by lugs L, riveted to the inside of the land-side, thus admitting of the sole-plate bethe beam at any desired height by the set-screw N. The beam A, rearward'of the standard C, is triangular in cross-section. This form combines lightness and strength and-forward of the standard the beam is rectangular in crosssection, the vertical sides being deepest, in order to resist the draft-strain.

I claim as my inventionl. The beam A, having clevis-head P, standard C, projections D E, and bifurcated handles B B, integrally formed therefrom, as set forth.

2. The beam A, formed triangular in crosssection rearward of the standard C, and forward ofthe same of rectangular form, for combining lightness 4with strength.

3. The combination of land-side H, pivoted to the standard C near its forward end, and provided with loop or keeper I,the beam A, provided with downwardly projecting arm D and the vertical set-screw J, said screw working in a socket in the lateral portion of the arm, and pivoted to Vthe keeper, 'and the keeper and land-side adapted to slide on the arm, as and for the purposes set forth.

4. The beam A, having curved standard C, whose lower end is provided with a triangular socket, formed wholly therein, in combination with the share G, having tapering triangular projection for attachment to the standard, as set forth. l

WILLIAM STEPHENS ON.
