UNITED STATES MARK GQOPER, ()F SPARTANBUBG, SOUTH CAROLINA.

PLOW.

SPECIFICATION forming part of Letters Application filed July 27, 1881.

To all whom it may concern:

Be it known that I, MARK COOPER, of Spartanburg, in the county of Spartanburg and State of South Carolina, have invented certain Improvements in Flows; and I hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification, in which-'- Figure l is a perspective view of. the plow. Fig. 2 is a vertical section. Figs. 3 and 4 are details to be referred to. Fig. 5 is a modificatiou.

My invt ntion consists in the combination of devices, as hereinafter described and claimed.

In order that those skilled in the art may make and use my intention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the beam of the plow, B the standard, and G the landside and back brace.

The standard is constructed of two bars, a a, which lie parallel, and at their lower ends are curved slightly forward to conform to the curvature of the plow D. A short distance below the. beam a bolt, d, holds the pieces a. a together. Above the beam the piece a is bent down over the top of the beam at right angles,

is made of a flat metal bar, 00, which is bent at the center to form a loop, and leaving the root Patent No. 247,989, dated October 4, 1881,

(No model.)

angular portion 2' to rest against the under side a bolt, 7a, which passes through it and the beam, and is secured by means of a nut, is. The two halves are then brought down to a point, I, where they are bent into a horizontal position, as showmand carried forward until they pass between the lower ends of the bars a a, and are secured to the. ends of said bars, together with an intervening solid shoe 01" piece, L, by means of bolt h. At the bend lanother bolt secures the shoe L to the two laps of the metal slot, 11:, between the shoe L and the beam between the sides of the back brace. In this slot moves or is fitted the shank of a grass-cutter, N, which is secured at any desired height by means of a nut, 19.

Fig. 5 illustrates a modification of my device, wherein the back brace and landsidc are made of one single solid piece of iron instead of with the double bars, as shown in the other illustrations.

Having thus described myinvcntion, what I claim as new, and desire to secure by Letters Patent, is-

The plow-standard constructed of the pieces a d, the piece a being bent at right angles above the beam, and passing through'the perferation in the-upper end of piece a, in combibolt h, all constructed and operated as and for the purpose'sct forth.

bar at. This construction leaves a long open of the beam, to which it is secured by means of 40 nation with and clasping the beam A and the
