JACOB REVERCOMB, OF BOTETOURT SPRINGS, VIRGINIA.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 11,201, dated June 27, 1851.

To dll whom it may concern:

Be it known that I, Jacob Reveecomb, of Botetourt Springs, in the county of Roanoke and State of Virginia, have invented a new and Improved Mode of Fastening and Regulating the Nose or Point of Self-Sharpening Plows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention cousists in seeming and regulating the nose or point of self-sharpening plows by means of wooden or iron wedges introduced through a hole made in the landside, whereby the point or nose can be accurately and easily adjusted, as well as firmly secured in its place.

To enable others skilled in the art to make and use m.y invention, I will proceed to describe its construction and operation.

I provide the nose or point &amp; of a self-sharpening plow with an oblong slot, c, (see Figure 1 in accompanying drawings,) in the stem a. The point a is introduced into the mold-board d (see Fig. 2) through an opening made in front of said mold-board, and in order to keep the point a steady and firm in its place I provide the point with a dovetail, e, (shown in Fig. 1,) into which the mold-board fits, as shown at f in Fig. 2.. The stem a of point.&amp; when introduced in the opening of the moldboard reaches through said mold-board and ranges with the inner side of the landside in such a manner that the slot c of the stein a comes exactly opposite a hole made through the landside for the purpose of introducing wooden or iron wedges, whereby the point can be firmly secured and accurately regulated.

The advantage of my invention, which is quite simple iu itself; is considerable in connection with self-sharpening points. The usual mode of fastening such points is not only difficult of access, but iu working the plow is liable to derangement, and for the most part such fastenings are not sufficiently strong. These difficulties are ail remedied by my mode of fastening through the landside, and experience has proved the practical value of this mode and the advantages as to a nice regulation of the point. It is cheaper than theusual methods, and very durable, as the wedge or key is not subject to wear.
