SPECIFICATION forming pm r Letters was No. 484,043, dated October 11 1892.

Application filed March 2, 1892. 3 Serial No. 423,513. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES P. MoWANE, a citizen of the United States, residing at Graham, in the county of Tazewell and State of Virginia,haveinvented a new anduseful Hillside-Plow, of which the following is a specification.

The invention relates to improvementsin reversible plows.

The object of the present invention is to simplify and improve the construction of the mechanism employed for securing the moldboards of reversible plows to either side of the latter and to enable the mold-boards to r 5 be readily detached from such securement at one side of the plow for turning and to be quickly secured at the other side.

The invention consists in the constructionand novel combination and arrangement of 720 parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a plow constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail perspective view of the rock-shaft and the operating-rod. Fig. 4 is a detail perspective view of the spring-rod and the seats therefor,

0 the parts being separated.

Like numerals of reference indicate corre sponding parts in all the figures of the drawlngs.

1 designates an iron plow-beam having in- 3 5 tegral standards 2, in which is journaled an inclined rock-shaft3,havingahookarm4, adapted to engage shoulders 5 at opposite sides of a mold-board 6, which is hinged at the bottom of the standards, and is adapted to swing beneath the plow to render the latter reversible. The hook-arm 4 is provided at one end with an opening to receive the rock-shaft, and is detachably secured thereto by a screw 7. It works through a slot 8 in the standards 5 2, audit is provided at its outer end with oppositely-disposed hook projections 9, which engage the shoulder 5. The outer or upper end of the rock-shaft is provided with an eye 10, to which is secured an angularly-bent end 11 of an operating-rod 12, which has its upper end provided with a handle 13 and which is journaled in an eye 14: on a cross-bar 15, which connects the plow-handle 16, and the said opcrating-rod is adapted to turn the shaft to carry the hook-arm from one side of the plow to the other.

, The hook-arm of the rock-shaft is held in engagement with the shoulders of the mold board by parallel spring-rods 17, between which is arranged a flattened portion 18 of the rock-shaft, and which are adapted to engage the flattened portion to hold the rockshaft against turning. When the mold-board is swung from one side of the plow to the other, the shoulders 5, which are beveled at their outer sides,automatically engage the hook-arm 4. The parallel spring-rods are arranged in sockets formed by the grooves 19 of a projection 20 and grooves 21 of a removable plate 22. The projection 20 is arranged at and depends from the upper end of the standard, and the removable plate 22 is socured to the projection 20 bya bolt 23, which causes the plate 22 to clamp the spring-rod.

It will be'seen that the means for securing reversible mold-boards in operative position at the sides of plows are simple and comparatively inexpensive in construction and are adapted to permit a mold-board to be quickly turned and secured at the other side of a plow.

I do not wish to be limited to the particular construction of the spring, as shown, as some other construction and arrangement of spring could be adapted for use and answer every purpose. I therefore reserve the right to make this and other modifications in the mechanical workmanship without departing from the spirit or sacrificing any of the advantages of my invention.

What I claim is 1. The combination, in a plow, of a standard having an inclined slot and provided with bearings at opposite sides of the slot, said bearings extending to the rear edge of the standard, a rock-shaft journaled in said bear- 9 5 ings and extending upward from the rear edge of the standard, an arm secured to the rock-shaft and arranged in the slot and adapt ed to swing through the same and provided at its outer end with oppositely-disposed hook projections, a hinged mold-board provided at opposite sides with shoulders adapted to be engaged by said hook projections, and a .rod having its lower end connected to the rock shaft and adapted to extend to the-handles of a plow and provided at its upper endwiith a handle, substantially as described.

2. In a plow, the combination of a standard, a hinged mold-board provided with opposite shoulders, a rock-shaft jou-rnaled on the standard, a hook-arm" carried by the rockshaft and adapted to swing to opposite sides of the standard and provided at itsouterfend with oppositely-disposed hook projections adapted to engage said shoulder, and a spring for holding; the v rock-shaft againstturning to maintain'the hook projections in engagement with the shoulders, substan'tiallyasdescribed;

3. In a plow, the combination of a standa'rdgiaa moldtboardhingedz at .thebot'tomr of. the standard and. pro'vid'ediat-opposite sides with shoulders, a rockz-s-hatt'journaled'omthe stand ard and provided with a hook-arm adapted toiengage either one of the shoulders and having an intermediate:- flattened portion, springs: bearing; on the flattened portion and adapted to hold the hook-arm: in engagement f withitheshou-liders, andmeans for'turnin-g th e roclc-shafit,substantiallyas described; L

4. The combinationiofi astandardiprovided with: a: slot-,iai mold-board? hinged: atlthe bottom of the standard and having shoulders at .i the opposite sides, a rock-shaft journaled on the standard and having a flattened portion shoulders of the mold-board, a projection extending-115mm the top of the standard and provided with grooves, a removable plate arranged on the projection and provided with g grooves parallel. resilient rods-r clamped in said grooves and arranged on opposite sides of"the*sa-idflattened portion of the rock-shaft,

and an operating-rod extending from the irock shaft and connected therewith=- and a'd'aptedz to extend toi the hand lesiofi" at plow,

substantially as described.-
