HILLSIDE-PLOW.

SPECIFICATION forming part of Letters Patent No. 555,655, dated February 18, 1896.

Application filed November 9,1895. Serial No. 568,492. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALBERT C. RosEN- ORANZ, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Hillside- 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.

My invention relates to improvements in re versible' hillside-pl ows.

The invention consists of the combination, in a plow, of a reversible moldboard, a double moldboard-catch comprising two hook-arms connected to a central portion, which is pivoted to the plow, the periphery of said central portion being eccentric to said pivotpoint, and a spring mounted on the plow and having a curved end adapted to engage said eccentric periphery to hold said catclrin its adjusted positions.

It also consists of certain other novel constructions, combinations, and arrangements of parts, all of which will be more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents a side elevation of a hillside-plow with my invention applied thereto. Fig. 2 represents a rear elevation of the same. Fig. 3 represents a detail top plan view of the pivoted catch. Fig. 4 represents a detail central vertical section through the rear of the plow-standard and the pivoted catch,and Fig. 5 represents a detailperspective view of the guard-roller which is journaled at the front of the standard.

A in the drawings represents the plowstandard; 13, the moldboard; O, the pivoted catch, and D the guard-roller for assisting weeds and the like in passing the front of the plow.

The front of the standard A is provided with a bracket a, which is formed with a conical projection ct upon its upper surface. The guard-roller D is provided at its lower end with a conical recess d, which fits over the projection a, and thereby forms a journal for the lower end of the roller. The upper end of the roller is journaled on a pin a pendent from the standard A, which is con structed to overhang the upper end of the roller. The roller is preferably made larger at each end than in the middle, gradually sloping inward from each end, so as to form a shallow groove about the roller. This construction keeps any obstruction, which is pressing against the roller, in the middle of the same, so that it will not run oif the same at either end.

Any weeds, grass, or other obstructions striking the plow will ride up the front and press against the roller and, as the plow continues to move forward, the roller enables the obstruction to pass smoothly to one side without materially hindering the advance of the plow.

The catch 0 consists of two curved hookarms 0 c, which spring from a central portion 0. This central portion is provided with a central aperture 0 which is journaled on a stud a formed on a bracket a of the standard. The central portion 0 is recessed about the top of the aperture 0 to accommodate a washer 0 A bolt f passes through the said washer, aperture 0 stud a and bracket a, the head of said bolt resting on said washer. The bolt is secured by washer and nut f f respectively.

The periphery of the central portion 0' at the rear is eccentric to the pivot-point, and said central portion is provided with two stopshoulders c 0 the use of which will be hereinafter more fully described.

A spring H is secured in a groove a of the standard by a transverse rivet 0, which passes through the walls of the slot and rests against an angle h, formed in the upper end of the spring by a portion h of the same, which is bent at right angles thereto. The bottom of the groove a is cut deeper just below the rivet a so that the whole lower end of the springis free to vibrate. The lower end of the spring is enlarged and curved transversely so as to exactly fit the eccentric periphery of the central portion 0. When the catch is supporting the moldboard on one side by hooking over one of its supports 19, the lower end of said spring is abutting against either one or the other of the shoulders 0 0 which thus limits its movement in that direction.

When the catch is supporting the moldboard on either one or the other side, the spring is pressing against the eccentric periphery to one or the other side of its pivotal point, and said catch is thus held firmly in either one or the other position. The 1noldboard is pivoted in any suitable manner to the standard so as to be swung from side to side, as required.

It will be observed that by my construction the spring is not perforated or weakened in any way by its fastenings and securely holds the catch in its adjusted position, but still permits it to be instantly changed to an opposite position without any other operation than forcing the catch into said latter position.

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

1. In a plow, a reversible moldboard-catch comprising two hook-arms connected to a central portion which is pivoted to the plowstandard the periphery of said central portion being eccentric to said pivot point, and a spring mounted 011 the plow-standard and having a curved end adapted to engage said eccentric periphery to hold said catch in its adjusted positions,substantially as described. 2. In a plow, a reversible moldboard, a standard for supporting the same provided with a spring-receiving groove, a double moldboard-catch pivoted on a bracket of said standard and comprising two hook-arms connected to a central portion having a pivot-aperture; the periphery of said central portion being eccentric to said pivot-aperture, a stud on said bracket, on which stud the catch is pivoted, and a spring mounted in the groove in said standard and engaging the eccentric periphery of the catch to hold the same in its adjusted positions,substantially as described. In testimony whereof I hereunto aiiix my signature in presence of two witnesses.

ALBERT C. ROSENCRANZ.
