DOUBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 240,642, dated April 26, 1881. Application filed September 4, 1880. (No model.)

To all whom it may concern:

Be it known that I, ANDREW BEARD, a cit-izen of the United States, residing at Easonville, in the county of St. Clair and State of Alabama, have invented certain new and useful Improvements in Double Plows and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

The invention has relation to double or gang plows, the plow-plates of which may be arranged with relation to each other closer or more remote by proper adjusting means and the novelty consists in the construction and arrangement of parts, as will. be more fully hereinafter set forth and specifically pointed out in the claims.

The invention consists, first, in a peculiar plow-standard bent to form an approximate semicircle to give proper and convenient bearings above to be secured to the frame, and below to have the shovel or plate attached to it and braced from a point above where the standard begins to assume a nearly horizontal plane to a point below where the standard reaches forward, by a suitable arm, in such a manner that the portion of the standard between the points of brace-connection will embrace the eakest portion thereof, or the portion where the greatest strain isliable tooccur; second, in the standard, braced as shown, combined with the means for its adjustable connection above, and means for adjusting its position with relation to its fellow or fellows.

In my device much less metal may be used than in the ordinary construction, the brace compensating for its lack in the parts where the strain is greatest.

In the accompanying drawings, Figure l is a sideelevation, showing the curved standards and braces; and Fig. 2 a top-plan view, showing the adjusting means.

Referring to the drawings, Arepresents the plow-beam, B the handles, and O the round.

are secured by the bolts G to the ends of the swinging cross-bar D. The curved portion it? of the standards, where the great strain while in use is borne, is braced by an arm J, as shown, bolted between the sidcparts of the standards.

Braces F are secured to the beam by bolts 1,

so as to be adjusted at will.

It will be observed that the shovel-standards are secured to the swinging bar I), which is pivoted to allow a very large range of adjustment, hence it would be impracticable to brace the standards directly to the plow-beam in the usual manner. I therefore extend a brace across the curve of the standard at the point where the greatest strain comes, and bolt it between the side parts of said standard. It thus is operative when the cross-bar is swung to any position, and renders the curved standards stiff and serviceable with a very light weightof metal. The cross-bar D is held in any adjustment by the perforated braces F and bolts G I.

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

l. The curved standard or dragbar H, formed of a double bar of iron and having a brace, J, inserted between the sides and across the bend, whereby the standards are stiffened and braced in anyposition to which the swinging beam may be moved.

2. The combination of the curved standards H, the braces J, the swinging cross-bar D, plow-beam A, and braces F, substantially as shown and described.

ANDREW BEARD.
