JOHN T. THOMPSON, OF JACKSON, TENNESSEE.
IM PROVEM ENT IN PLOWS.
Specification forming part of Letters Patent No. 28,919, dated June 26, 1860.
To all whom it may concern:
Be it known that I, JOHN T. THOMPSON, of Jackson, in the county ot' Madison and State ot' Tennessee, have invented certain new and useful Improvements in Plows; and I do hereby declare the followingto be a full,elear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specilication, in which- Figure l represents a perspective View of the plow complete. Fig. 2 represents a perspective View of the stock with the mold-board removed. Figs. 3 and 4 represent perspective views of dierent mold-boards or wings that may be used on the stock.
Similar letters of reference, where they occur, denote like parts ofthe plow in all the figures.
My invention relates to the construction of theplow and the manner ofuniting the several parts thereof, as will be explained in connection with the drawings.
The beam A and handles B may be of wood, and made and united in anyof the well-known ways.
O is a skeleton-frame having two Vertical sides, a b,and one horizontal side,c. The Vertical side or piece a serves as a brace and colter both, its front edge being sharpened to divide the earth. Its top is furnished with a foot or bearing-piece, upon which the beam lies, and to which the beam is bolted by a bolt, c. The other vertical piece, b, has also a foot or bearing,f, upon which the beam also rests, and to which the beam is bolted by a bolt, g. The third side or piece forms the sole of the plow, and the whole makes afranie-work to which the wings and pointare attached. The piece a has bolt-holes, h h, through it, and the point t' ofthe frame is flattened ont and furnished with a bolthole,by which the plowpointj, is secured to it.
The mold-boards or wings D havea flange, k, upon them, furnished with bolt-holes corresponding with those hh in the piece a, through which bolts pass to secure the pieces firmly to the stock. The mold-boards or wings set a little back of the front or cutting edge of the piece a, and at their lower ends overlap the upper part ofthe plow-pointy', which plowpoint has a slot in it, soas to straddle the colter-piece a.
I have represented the plow in Fig. 1 as having two mold-boards or wings. One only may be used when the particular character of the work or ofthe soil may require it, and these mold-boards may be more or less curved or inclined from the colter to their extremities, but always curved or inclined vertically to suit the curvature 0r inclination of the colter.
.Having thus fully described the construction of my plow, what I claim. is-
Thei'rameG, with its plow-point j, and wings o r mold-board D, when the whole is constructed, arranged, and united as herein set forth and described.
