IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 135,363, dated January 23, 1873.

To all whom it may concern:

Be itknown that I, EDWIN REESE, of Enta-w, in the county of Greene and State of Alabama, have invented ,an Improved Plow, of which the followingis a specification:

The invention relates to self sharpening plows; and consists in a peculiar construction of land-side, by which the point and edge of share are allowed, in a certain and uniform manner, to wear upon both upper and lower sides, so as to retain the same angle of edge As the land-side G of a common plow abuts against the bottom of the share, it takes a portion of the wear from friction, and does not allow the point to be abraded horizontally on its bottom, butcompels the abrasion to take an upward turn,- and soon dubs it off. This is the condition iu'which'we find a share when removed from the plow in order to be resharpened. To avoid this difficulty I form the landside of two pieces, D E, and leave a vacant space where the part 0 of an ordinary landside is placed. This gives the bottom of point and whole edge of share an opportunity to wear oft in a horizontal plane, and thus maintain each at a constant angle and always sharp. Hence, with my invention, after a steel share is once attached to a plow it becomes selfsharpening, and never requires removal until worn down so as to be inthe same plane with the bottom of piece E and mold-board A. In order to give to the plow the support required from the land-side the part D is sloped at d, and has a flat surface, d, which rests on the bottom of the furrow. The part E of land-side has a riser, e, which fits into a recess of the "mold-board, and is bolted thereto. The ends d e of the two parts of land-side form a socket-joint, and allow D to be lowered or elevated at any time to cause the plow to run squarely and on a level. H is a rod, flattened and provided with a slot or several perforations, h, at the upper end. By bringing one and another of these perforations about the holdingscrew h of standard G thepartD of land-side may always be fastened at any desired adjustment.

Of course 1 am aware that self-sharpening shares and points are not new, broadly, and I only intend to claim my particular construe tion of land-side, by which I can more conveniently, easily, and eflectually make them selfsharpening.

Having thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

A bottom concaved landside, having the rear section D jointed to a fixed section, E, for the purpose of giving angular adjustment to the rear section of land side as the bottom of share wears, and thus preserve the cuttingedge of said share always at or about the true angle.
