IMPROVEMENT IN SHOVEL-PLOW PLATES AND POINTS.
Specification forming part of Letters Patent No, 97,2113, dated November 3, 1869.
To all whom, t may concern.;
Be it known that I, HENRY MILLER, of Roadside, in the county of Rockingham and State of Virginia, have invented a new and useful Improvement in Shovel-Plow Plate and Points; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the saine, reference beinghad to the accompanying drawings, making a part of this specification, in which- Figure l is a plan view of the plate and points, and Fig. 2 is an edge view of the same. Fig. 3 is a plan of the rear side.
This invention consists of a plow plate or mold to be secured to any plow-stock, its face being concave lengthwise and dat crosswise, and the mold having seats at its ends into which are placed reversible points of shape suited to the seats.
In the drawings, A is the plow-plate, made of cast or malleable iron, and reversible on its fastening-bolt, so as to point downward the end best adapted to the work in hand. Its face is concave lengthwise of the mold, so as to give a proper set or draft when either end is down, and iiat erosswise of the mold, so as to start the ground upward instead of pressing it horizontally against the unplowed ground on either side, as plows with convex faces do. The result is lighter draft, greater steadiness of the plow, and more thorough pulverization of the soil. The mold has seats at its ends far the attachment of the points A A, one of which is a triangle with curved sides, and the other diamond-shaped. The seats are of such shape as to always compel the presentation of one of the angles of these point-plates to the soil, and are cupped in order to insure a close fit and give greater firmness to the points when bolted in their places, at which times the points present smooth surfaces, and even, or nearly so, with the mold. The bolts which fasten the points pass through slots in the molds to preserve close contact between the edges of the point and seats when the former are worn, the design being to shift the points in their seats so as to present fresh angles to the soil when the preceding ones have become dulled, and when all the angles have been presented in turn, to invert the points A A and make their edges sharpen themselves, which they will do effectually. The mold has a rib, A, lengthwise of its back to increase its strength and securely lock it to the plow-stock when the latter is provided with a groove for the reception of the rib. The points may be made of steel or castiron, according to the nature of the soil.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The mold A, having a face concave lengthwise and plane crosswise, and having seats at its ends, substantially as and for the purpose set forth.
2. The combination of the mold A, having seats at its ends, with removable reversible points A. A, substantially in manner and for purpose described.
- HENRY MILLER.
