JAMES ALBERT COLE, OF JULIAN, ALIFORNIA.

REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 396,142, dated January 15, 1889.

Application filed June 29, 1888. Serial No. 27s,5s5.' (N0 model.)

To all whom, it mayconccrn:

Be it known that I, J AMES ALBERT COLE, of Julian, in the county of San Diego and State of California, have invented an Improvement in Reversible Flows; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to that class of plows in which a double bottom is arranged to be turned from side to side, whereby it may be used as a right or left hand plow, these implements being specially adapted for use on side-hills, from which they are commonly called side-hill plows.

My invention consists in the general construction and arrangement of parts hereinafter described, and also in the locking devices for the plow-bottom, whereby it is held in position and may be readily released to turn to the other side. I

The object of my invention is to provide a simple and effectivereversible plow which can be used on level ground as well as on side-hills.

Referring to the accompanying drawing, the figure'is a perspective view of my reversible plow. I

A is the plow-bea1n, having its rear portion slotted at a, and B is the rear standard secured to the beam, and to which the handles are to be properly secured.

C is the forward standard, having its upper end secured to the beam, and in its lower end is mounted the pivot-shaft D, secured to the mold-board in front and having its rear end mounted in the lower end of the rear stand ard, B.

E is an inclined double-or slotted brace bolted to the rear standard, to the forward standard, and to the beam A.

F is the double mold-board, and G arerearwardly-converging landsides securedin front to the double mold-board and at their rear ends to the pivot-shaft D.

H is the locking-lever. It is slotted over the pivot-shaft D, so that it may fulcrum on said shaft in a forward-and-back movement. The lower end of the lever is provided with an eye, 72, which is adapted to engage either of the lugs f on the back of the doublemoldboard.

The lever H passes up through the slotted brace E, and through the slotted rear end, a, of the beam A, and is adapted to be held in position by a pivoted catch, Z), on the rear standard.

The operation of the plow is as follows: The plow-bottom is held in position on either side by the engagement of the lower end of lever H with the lower lug, f, 011 the back of the mold-board, and the lever itself is held by the pivoted catch 6, which engages its upper end. hen it is desired to reverse the plow-bottom, the catch 6 is thrown up to release lever H. The upper end of said lever is then thrown forward, whereby it fulcrums on the pivot-shaft D and withdraws its lower end from engagement with the mo1d-board lug f. The plow-bottom is thus released and may be turned about, or with its pivot-shaft Das a center, to the other side, its limit of movement being fixed by the contact of its upper landside with the forward standard. Then the lever H is again thrown to its engagement with the mold-board lug f and secured by the pivoted catch 1). The slotted beam and the slotted brace serve as guides for the locking-lever H in its movement, and the whole implement is simple and strong in construction.

I am aware that reversible plows are well- 'known, and I do not claim such, broadly, as my invention, but limit myself to the con.- struction shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a reversible plow, the beam A, having a slotted rear end, a, and the forward and rear standards. secured to the beam, in combination with the pivot-shaft mounted in the lower ends of the standards, the double moldboard and landsides on said shaft, the lugs f on the back of the mold-board, the lockinglever H, fulcrumed on the shaft, so as to move forward and back, and having an eye on its lower end for engaging the mold-board lugs, said lever passing upwardly through the slotted rear end of the beam, and a catch for securing it to the rear standard, substantially as described.
