PLOW.

SPECIFICATION forming part of Letters Patent N 0. 471,290, dated March 22, 1892.

Application filed October 29, 1891. $eria1No. 410,186. (No modeL) To all whom it may concern.-

Be it known that I, FRIEDRICH HUENER- JAEGER, of Michigan Oity,in the county of La Porte and State of Indiana, have invented a new and useful Improvement in Plows, of

' entirely with the ordinary form of adjustable mold-board adapted to be shifted from one side to another, and in lieu thereof providing a simplified arrangement whereby the same, if not better, results are attained with a much less complicated structure.

WVith the above object in view the invention consists in the improved construction and combination of parts, as hereinaftermore fully set forth and. described.

In the accompanying drawings, Figure 1 is a side elevation of a complete plow embodying my improvements. Fig. 2 is plan view thereof, and Fig. 3 an end elevation.

Like letters of reference refer to like parts throughout the several views.

Referring to the drawings, the letter A indicates the plow-beam, which at its rear end has secured thereto a downwardly-curved metallic arm B, through which the handle or lever 0 passes, the lower end of said arm being secured to a base-piece D. Extending also from the arm B at an incline is a plow-beam E, which is secured to the forward end of the base D, and carries upon its lower extremity the plowshare or cutter F,which is of approximately spade-shape form. The transverse axis of the share or blade is substantially at right angles to the beam A and the arm B. It is of course obvious that instead of providing a separate arm, as B, the beam may be extended rearwardly and curved downwardly in the same manner. I prefer, however, to employ a separate metallic arm, inasmuch as the same affords a more secure means for attaching the handle, plow-beam, and other parts.

The letters G G indicate the sulky-wheels at the forward end of the machine, mounted upon a fixed axle H. Extending upwardly from this axle is a yoke-shaped frame-I, the vertical members of which are provided with a series of perforations t' 2'.

The letter J indicates a transverse supporting-bar adjustable vertically on the frame I, to which are attached near opposite ends short chains K K, said chains carrying pins L L upon their free ends. These pins are adapted to be passed through any of the series of apertures in the vertical pieces of the standards and to receive thereon the under edge of the opposite ends of the transverse bar, which lat ter in turn is adapted to support movably the forward extremity of the plow-beam in the manner clearly illustrated by the dotted lines, Fig. 3.

To the rear side of the axle H is attached a clevis M, which receives one link of a draftchain N, the opposite end of said chain being attached to a hook 0, extending from arm B.

When the plow is in operation with the beam adjusted to the position illustrated in the drawings, or to the left of the transverse supporting-bar, the plowshare or cutter is necessarily slightly inclined to the left, which of course has the effect of throwing the soil in the same direction. When the end of the furrow is reached, instead of the necessity of shifting a mold-board, as is done in side-hill plows, as is ordinarily the case, all that is necessary to be done is simply to turn the plow to the right and then throw the end of the plow-beam resting upon the transverse supporting-bar from the left to the right, this being accomplished by merely manipulating the handle. It will be noticed that the transverse bar J upon its upper edge is rounded at a central point, whereby the plow-beam is more readily maintained in its adjusted 0blique position.

The line of draft can be shifted with equal ease and expedition, inasmuch as the link of the draft-chain is loose upon the clevis, so that as the end of the plow-beam is changed from left to right, or vice versa, the forward end of said draft-chain may be likewise adjusted.

In this way the draft is readily equalized, as the draft-chain is thus maintained ina straight line, as clearly illustrated in the drawings. 1 have also shown a means for adjusting the depth of penetration of the plowshare. This is accomplished by merely raising or lowering the transverse supporting-bar J and inserting the pins L L in different apertures of the yoke.

In use the bar J is first adjusted to a proper height to cause the plow to cut a deep or shallow furrow, as desired, and thereupon as the plow is moved forward the wheels G G travel, one on the plowed and the other on the unplowed land, and the plow runs in the unplowed land near its edge, and the blade or shaft, being at an oblique angle to the line of motion of the plow, cuts the sod or unplowed land and turns the slice over away from the same. 011 reaching the end of the furrow and upon turning the team and plow around to go in the opposite direction the front end of the beam is shifted laterally to the other side of the yoke I, and the blade is thus put into a reverse oblique position, whereby it is made to cut the sod or soil and turn the slice away from the unplowed land, as it did while moving in the opposite direction. The plow is steadied and held to its work by the attendant, who grasps the handles therefor. As will be seen, the plow is adapted to work in both directions along the same edge of unplowed land, in both cases turning the soil away from the unplowed land. The chain N is located or shifted in the clevis M, as is necessary to secure the proper draft to the plow.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. The combination, with the axle of a plowsulky and a laterally-extending yoke mounted rigidly on the axle, of a plow-beam the forward end of which rests and is movable laterally freely on the yoke, a plow-point rigid to the rear part of the beam, a handle secured rigidly to the beam, and a nonrigid draft device connecting the rear end of the beam to the axle of the sulky, substantially as described.

2. In a plow, the combination of a yoke secured rigidly to the axle of the plow-sulky wheels, a clevis extending from the rear side of said axle, a plow-beam having its forward free end resting upon said yoke so as to have a free movement, a plow-arm extendingfrom the rear portion of the beam and provided upon its lower end with a plowshare or cutter, a handle or lever for throwing the forward end of the beam from one side to the other of the supporting-yoke, and a draft-chain having one end sliding loosely on the clevis and its opposite end secured to the plow-beam, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
