UNITED STATES PATENT OFFICE.
JOHN A. STEWART, OF PHILADELPHIA, MISSISSIPPI.
IIVI PROVEM ENT IN PLOWS.
Specification forming part of Letters Patent No. 30,263, dated October 2,1860'.
`To all whom it may concern:
Be it known that I, JOHN A. STEWART, of Philadel bia, in the county of Neshoba and State of l ississippi, have invented a new and useful Improvement in Seed-Planters; and I do hereby declarethat the following is a, full, clear, and exact description of the san1e,refer` ence being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a perspective view, and Fig. 2 a bottom view, of the plow.
Similar letters of reference in each ot' the several gures indicate corresponding parts.
The nature of my invention consists in the arrangement of an adjustable triangular point, perforated,cutter and landside, also perforated and adjustable, and the moldboard of a plow.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
The mold-board A of thisplow is made with v a standard, E, and landside-artn P. The up'- rper end oi' the standard is bolted to the beam O in the usual manner, and the rearend ofthe arm P is secured to the lower end of the part Il of the plow-frame by means of a bolt, G'. A flange, Q, extends from the bottom edge of mold-board to the arm P. A short pin, I, f te from the bottom surface ot'said flange. A 1.1..,Langular point, O, provided with three holes, J' J J', is placed against the under side of said flange, so'tilat the pin I will tit into'the central hole, J A bolt,-I', passing; through a hole in the ilange and one'of the holes J', serves to secure the pointin place.
It will be seen that the point is made with two cutting-edges,B B, and by nnscrewing and removing bolt I' the point O can be taken oli' j and reversed. The pin I can then be reinserted into hole J and the bolt I' be passed through the hole in the flange and the other hole, J In this manner the point can be reversed, and thus when one of the'cutting-edges B B has been worn out or become dull the other o ne can be brought into action.
The shank of the bolt G' and lthe shank of a bolt,G, near the standard, pass through suit-` able holes in the arm P, and through two of a series of holes, H, in the landside D. In this manner the landside D is secured iu place, and it may be adjusted more or less forwa'rd by means of unscrewing -tbe bolts G G' and pass-4 ing them through any other two of the holes H. By thus adjusting the landside its cuttingedge D', when worn ofi' or reduced by sharpening, can always be placed in proper position in relation tothe mold-board and point of the plow.
This plow will be found to prove servicea ble for a much longer period than any otbe similar implement.
What lei-aim as my invention, and desire to secure by Letters Patent, is j The arrztxiggerileiit of an adjustable triangu-- lar point, C, perforated at J' J J', cutter and landside D, also perforated and adjustable, and. mold-board A of a plow, the whole constructed substantially as and for the purposes set forth.
The above specification ot' my improvement in seed-planters signed by me this 13th day of July, 1860.
JOHN A. STEWART.
