EMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 42 26 1, dated April 12, 1864.

To all whom it may concern:

Be it known that I, SAMUEL ALAND, of Rome, in county of Oneida and'State of New York,have invented anew and Improved Mode of Constructing subsoil-Flows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the let ters of reference marked thereon.

The nature of my invention consists in providing a subsoil attachment wherein the shoe is placed back from the plow a sufficient distanoe to admit of its clearing itself in a superior manner; also, of adjusting the standard both at the upper and lower ends, in order to obtain the proper pitch of the shoe, together with the brace and crossbar, which, as combined and arranged, produces a practical and Seperior improvement.

To enable others skilled in the artto make and use my invention, 1 will proceed to describe its construction.

A, Figure 1, is a perspective view of a plow, showing the subsoil attachment in the rear. The standard B is extended below the bottom of the plow, as when in use.

C, Fig. 2, is a longitudinal sectional view of the standard, notched. bar 0, and cross-bar D. The notched rod may be attached to the standard in any convenient manner that will admit of a free movement up and down. The other end is provided with notches or depressions of any suitable form that may be re-.

quired to secure it to a lug, G, cast on the mold-board or bolted to the landside; or it may be made to hook over a bolt passing through the plow in any way that will render it adjustable. The standard B is madeeither of wrought or cast iron, and in all cases should be made in such shape and form as to throw the shoe back a sufficient distance from the mold-board to allow it to clear itself readily in all kinds of soil. It will also be seen that the front and upper part of the standard must be provided with teeth or notches to agree with the inside form of the mortise in cross-bar D, said mortise being constructed with a V in the front side to engage and fit the depressions in the standards, where it is easily and firmly secured by wedge E. The sides of the mortise should also be rounded sufficient to allow the standard to rock back and forth to obtain the required pitch of shoe. One end of the cross-bar is made to extend under the rear end of the plow-beam in the form of an angular brace, F, which serves, when so constructed, the double purpose of securing the beam to the handle of the plow, and also admits of its being readily adjusted sidewise, and retained in any desired position.

It is evident that the rod 0 can be made in various ways and attached to the standards and plow by different methods that will admit of the parts being adjusted to the different form and styles of plows without changin g the nature of the invention.

I am aware that plows having subsoil attachments somewhat similar to this have been made; also, that the rear end of a plow-beam has been made adjustable. I do not therefore claim, broadly speaking, a subsoil-plow having an adjustable beam; but

I claim- The combination of the mortised cross-bar D, standard B, brace O, and lug Gr, constructed and arranged to operate as and for the purpose herein set forth.

SAMUEL ALAND.
