Unten STATES IMPROVEMENT IN HlLLslnE-Ptows.

Specification forming part ot' Letters Patent No. Ll, dated September 9, 1845.

To all whom 'it 'may concern Be it known that I, JOSEPH TRUMP, of Connellsville, in the county of Fayette and State ot' Pennsylvania, have invented a new and Improved HillsidePlow; and I do hereby declale the following to be a full and exact ndescription ot' the same, reference being had to the accompanying drawings, making a part of this specification.

The nature of my invention consists in connecting a right and left hand plow of the usual form together, back to back, and attaching thenrto a beam in such a manner that by the disengaging oi' a springlatch or ratchet the beam is freed from its connement and is,

` justing itself the instant it reaches its proper position for operating the other plow. By

' my improved plow an entire field can be plowed and every furrow turned in the same direction without the plowed furrows being trampled upon with less labor than the usual process by plowing around a ield.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure l is a perspective elevation ot' my entire plow. Fig. 2 is a perspective elevation ot the share side thereof, with the beam and shifting continuation mold-boards detached. Fig. 3 .is an elevation of the landside of my plow detached from'the beam. Fig. et is a vertical longitudinal section of the beam, ratchet, bolt, conmeeting-cap, `Src.; and Figs. 5 and 6 are repre sentations ofthe front and back sides of the shifting moldboards.

The right and left hand plows, (L and b, may be constructed in any known or usual manner, their backs secured firmly to each other, and their posts or uprights securely fastened to an oblong cap-piece, c, at the top. Midway between the two plows-dividin g the permanent portion of the mold-boards of eachthere descends an oblong opening, A, having the connectionsfand h at its top and bottom. Into the opening A the shifting moldboards d d are secured, back to back, by a bolt, e, passing through the connectingpiece f, (at the top of the opening A,) and in descending passing through the holes in the projections g g on the back of cach moldboard, and entering into and secured to the connecting crosspiece h. The shifting mold-boards l d turn freely upon the bolt e, andthei'r inner edges, upon which the shoulders i c' are placed, coineide exactly with the sides ofthe oblong opening A, thereby forming a continuation of the permanent portion of the mold-boards of each plow. When the beam B is shifted from one plow to the other the shifting mold-boards d d fall back into their proper position by the action of the earth against them. rlhey are retained in this position by the ears i t', projecting from the inner rear side ot` each shitting mold-board, which pass under the ed ge ofthe permanent portion ot' the mold-board ot each plow, and acting against the bolt e retain the edges of the permanent and shifting moldboards together and their sides at a unit'orm and proper angle of inclination.

The connection cappiece c has an oblong .cross-opening, 7c, in its center, through which a strong bolt, m, descending through the beam B, passes, and secures the cap-piece c, and the double plowsattached to the same, to the beam. There are notches a n in each end of the cap piece c, into which the spring-ratchet P is pressed by the spring q, which permanently secures the cap-piece c in its proper position parallel with the beam of the plow. The ends of the connection cap-piece c are rounded ott' on each side oi' the notches a n, for the purpose of enabling the ratchet or spring-latch P to pass into the notches an when the beam of the plow is carried around.

The object ot` making the opening k of an oblong form is for the changing the position of the plow and beam and adaptin g it to plowing a wide or narrow furrow, which is effected by changing the position of the bolt m to either Y end or the middle of the spring 7c by bushing upon one or both its sides. The lower end of the ratchet P has a shoulder projecting under the cap c for the purpose of more rmly securing it and preventing its springing. The ratchet P works on a pin at its center, and there is a cord or wire, r, carried from the top of the same to the handles of the plow, by pullu ing which the holder of the plow, when he reaches the end of his furrow,detaches the ratchet, and the team in coming around turn around the beam -of the plow to its proper place '2 f LESS Y liasjust plowed and making a return-furrow in the same direction of the first.

The spiral spring q is placed between the holt-head on and the ratchet P.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The manner o'connecting the right and left hand plows, aand b, to the beam by means of the cap-piece c, the bolt m, oblong opening k, self-acting spring-latch P, and notches n n, all combined and operating substantially in the manner and for the purpose herein set forth.

2. The combination of the detaching-cord 1,

latch P, spring q, cap-piece c, and notches n u,

arranged and operating substantially as herein set forth.

JOSEPH TRUMP.
