(Ne Mofiel.) I W. K. HARRELL.
PLOW. No. 274,491. Patented Mar.2"7.1883.

WILLIAM K. HARRELL, OF OLARINDA, IOYVA.
PLOW.
SPECIFICATION forming part of Letters Patent No, 274,491, dated March 27, 1883.
7 Application filed November 9, 1852. (K model.) i
. To all whom it may concern plowing old ground-such as stubble, cotton,
and corn land, and the like.
In the drawings, Figure l is a side view of my invention. Fig. 2 is a top view thereof. Fig. 3 is a rear view. Fig. 4 is another side view. Fig. 5 is a vertical longitudinal sectional view. Fig. 6 is a. top view of a slightly modified form of share cutting-edge. Fig. 7 is a side view of the latter.
Referring to the drawings, A designates the share, which is formed with only a broad cutting-edge, a, at its front, the under side of the share being flat, as at a; for a short distance from edge a, which tlat portion will rest upon the ground. The face a? of the share is curved upward, with a slight bevel, c from the landside. The share or point A is also provided with a flange, a, at the landside, at the rear of which is formed a shoulder, c in the face a B is the mold-board, which is secured to the share A at its top edge, preferably by means of the back plate, 0, and bolts and nuts D, the latter passingthrough both the mold-board and share. The mold-hoard serves as a continuation of the share, its face I) being correspondingly curved upward and beveled from the landside, as at b. b is an extension of the top of the mold-board, the face I) of which exextension of the same. This equalization of course eft'ects a lossof friction and corresponding decrease in draft.
0 is the inner landside-plate, which is bolted to the inner face of the flange a l) is a curved brace bolted to and extending from the outer edge of the point ofjunctare of the share and mold-board to the inner face of the landside. The ends (I d of the brace D are preferably turned down to provide bolting-flanges, as shown.
E is a slide plate or runner, which is bolted to the under side of the brace D, as at e, from thence curved downwardly, e, and having the rear flat runner portion or extension, 6 This runner-plate E is parallel with the landside, but some distance therefrom, and serves to support its side of the plow, so that its point enters the ground horizontally, and the plow is retained in horizontal position, when the intact earth can pass up to the top of the moldhoard before it falls over at the side.
F is the colter or cutter, which is'formed integral with the outside plate, G, of the landside. The front lower edge, f, of the colter abuts against the shoulder a of the share, and thus the cutting-edge f of said colter is in line with the la-ndside-edge ot' the share, which'js very essential in some kinds of soil, as the cutting-edge of the share cuts away for the colter. Besides, in this manner the colter is more firmly secured to the plow.
The share represented in Figs. 6 and 7 of the drawings has its cutting edge entirely across the front; butinstead of being straight across the edge is semi-diamond or V shaped. This form of cutting-edge is preferred for use in timber and stony land. a
The advantages of my invention will be read ily understood. The construction is very simple, and the manufacture can be conducted at a minimum cost.
I claim as my invention- 1. In a plow, the combination of the share A, having a broad cutting-edge running at right angles from the laudside and formed as a thin horizontal wedge curved upward slightly at the rear,'and the mold-hoard increasing in curvature rearward and slightly twisted till its top rear edge stands in an oblique and nearly vertical plane, and having the outline In testimony that I claim the foregoing as substantially as shown. my own I have hereto affixed my signature in v 2. As an improvement in plows, the combipresence of two witnesses. nation, with the share, mold-board, and land- WILLIAM KING HARRELL. 5 side, of the flat slide-plate, E, secured to the Witnesses:
opposite side of the plow from the landside to P. SWISHER,
form a rear runner, as set forth. 7 i- T. T. PENDERGRAFT.
