WILLIAM RALL, OF SOUTH BEND, INDIANA.

IMPROVEMENT IN FLOWS.

To whom it may concern:

Be it known that I, WILLIAM RALL, of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Improvement in Plows; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure lis an elevation of my plow from the land-side thereof. same. Fig. 3 is an elevation of a cast-iron beam which may be used in place of the wooden one shown in the preceding` figures; and Fig. 4 is a cross-section of the point at w :c in Fig. 2.

Similar lettersof reference indicate corresponding parts in the several figures.

The nature of my invention relates to an improvement in the construction of plows, whereby there is secured, first, an adjustabil- 'ity of the beam, so as to lthrow the point of the plow to land or furrow as circumstances may require; second, the draft of the plow is central instead of lateral; third, the plow is, by reason of the peculiar construction of the land-side and standard, much lighter than a plow of the same size of ordinary construction, and yet strong, simple, and accessible in every part. The invention consists in the novel and peculiar construction of the point, standard, beam, and land-side of the plow, and their arrangement with relation to each other and the other parts of the plow.

In the drawing, A represents the cast-metal Y standard, being a web-like structure curved to fit under the mold-board B and point C, which are bolted to it. The head of the standard is flat and receives the rear end of a straight iron or wooden beam, D, which is pivoted to the front end of the head by a bolt, E, passing vertically through both, and secured by a screw-nut at the top. The head is prolonged toward therear and terminates in a T, in which there is a slot, a, up through which and the extremity. of the beam there passes the threaded end of a brace-bolt, E', whose lower end is secured to one of the handles F. The upper endvof this bolt is provided with a screw-nut, so that the beam may be turned to land or furrow, and secured at any point in Fig. 2 is a plan of the,

the radius of the slot a by screwing home the nuts, whereby the beam may be adjusted to land 7 or furrow to use two or three horses ling, however, a flange, c, at the bottom of the point, as shown in Fig. 4. The face of the short land-side is in like manner cut under, leaving a flange, c', at its bottom, which with the flange c, sets under the furrow-slice about one and a half inch, thereby steadying the plow. The short land-side is bolted to the plate above referredvto and the foot of the handle by a bolt, d, Fig'l, passing through all three.

It will be observed that the point is carried further back in this than in ordinary plows, and thus answers, in connection with the short land-side, in place of the full-length land-side in giving direction to the cut of the plow.

By placing the standard Well within the mold-board I secure a central draft, as the weight of the furrow-slice on the mold-board overcomes the natural tendency of the point to run to land.

The described construction of the land-side and standard affords an average reduction of twenty-five pounds of metal in each plow, reducing its cost correspondingly, rendering it easier to handle, and yet stronger than the plow of the usual construction.

The short, straight beam costs less in the first instance than the ordinary beams, and can easily be. replaced if broken, while, if an extra mold-board be furnished, a sod and stubble plow may be combined in the one implement, saving the expense of the extra plow.

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

The combination of the standard A, bracearms b b with the detached land-side Gr having the curved points, as described.
