ELIJAH S. WATSON, OF ST. LOUIS, MISSOURI, ASSIGNOR OF THREE-FOURTHS HIS RIGHT TO H. L. DUNCAN, O. MONTGOMERY, AND J. M. ALLEN, OF

WATER VALLEY, MISSISSIPPI.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 154,106, dated August 11, 1874; application filed January 17, 1874.

To all whom it may concern:

Be it known that I, ELIJAH S. WATSON, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and valuable Improvement in Flows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and. figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of my plow. Figs. 2, 3, and 4 are detail views of the same.

This invention has relation to the construction of plow-frames of metal, wherein it is desired to obtain great strength, and at the same time lightness and compactness, and a susceptibility for the attachment of one or several cultivating implements, as will be hereinafter explained.

The following is a description of my invention In the annexed drawings, A designates the plow-beam, which terminates posteriorly in a stock or standard, B, having the form of a semicircle. The lower end of this standard B is connected by a sole-bar, C, to a diagonal brace, D, which extends upwardly and backwardly to the stock B, to which it is rigidly fixed. Above and in line with this brace D is a stilt, E, the upper portion of which is beveled at a a, and perforated with several holes, one above the other. designates a dovetailed slide, which is applied to the upper beveled portion of the stilt E, and which is adjustable up and down thereon, and fixable by means of a screw, b, at any desired height convenient for the plowman. This slide has cast or otherwise formed on or applied to it two horn-shaped handles, ff, by which the plowman manipulates the implement. The beam A, the curved stock or standard B, the sole-bar G, and the diagonal brace D, together with the handle or stilt E, are cast entire of T-iron-that is to say, iron which in cross-section is the shape of the capital letter T. The sole bar is fiat on its bottom and has secured thereto a sole-plate, G, which may be made of hardened steel. This plate 0 has a shoe, 0, formed on its front end, into the rear portion of which the front end of the sole-bar is received, as shown by dotted lines, Fig. 3. Bolts and nuts d d are used for securing the plate 0' to the sole-bar G, by removing which bolts and nuts the plate 0 can be detached and a new one substituted.

My object is, as before stated, to give great strength to the stock. This I do, as it will be seen, by means of the diagonal or backwardlyinclined brace D, which I consider a great improvement in the class of plows herein referred to. By constructing the plow-beam and the stock or standard of T-shaped material I obtain great strength, both as regards lateral and longitudinal strain. At the same time a light plow is obtained.

The sole-plate shoe 0 is beveled on its uppersurface, as shown in Fig. 3, which corresponds to the double-beveled surfaces of the brace D; and the lower end of the brace D is made quite broad, so as to afford a good support to a single or double winged plow, cotton-sweep, or cultivator-blade, which are secured to the brace by means of bolts and nuts, as shown. G represents a subsoiler, which is formed on the lower end of a standard, 9, which latter is adjustable endwise, and is secured into slots made through the flanges of the stock B and the sole-bar O, and is notched into sole-plate G. H designates a diagonal brace, which is suitably secured to the standard g and to the beam A; and J designates a colter, which is secured at a to the beam A by the same bolt which secures the front end of the brace H to this beam. A brace,

J, resists any backward strain on the colter,

If wrought-iron is preferred in the construction of the beam and stock, I shall use L-shapcd iron and secure the flat sides together.

What I claim as new, and desire to secure by Letters Patent, is-

The plow-beam A, stock B, diagonal brace D, sole-bar O, and stilt E, all constructed .in one piece, as described. I

In testimony that I claim the above I have hereunto subscribed my name in the. presence of two witnesses.

ELIJAH S. WATSON.
