IMPROVEMENT IN GANG-FLOWS.

specification forming part" of Letters Patent No. 150,727, dated May 12,1874; appncation filed March 2l, 1873.

To all whom it may concern:

Be it known that I, JAMES STONE, of the county of Bond and State of Illinois, have invented a new.V and useful Improvement in My invention consists in the arrangement of a gang of plows upon curved beams of graduated length, which are pivoted in front to a frame, and connected together by a bolt rod passing through their rear curves, on which are placed sleeves, between the beams, to steady the plows, and. regulate their relative distancefrom each other, also, in the arrangement and combination of the lifting and brake levers, as will be hereinafter more fully set forth, to wit:

The rod Gr, which passes through the front end of each beamand the loops which go through the front part of the beam A, prevent the frame from being strained at its corners.

rlhe curved'plow-beams B, which are split at their lower ends, and which are attached to the bar of the plows B', brace themselves, and answer for both the upright and beam. The double loops E, carrying the revolving cutters F, are held on the same curved beams B by bolts, and are in front of the plow. The lever N, that works on the top part of the plowframe, with posts or eyebolts L holding the same, works with the branched cross-bar or brake M, and presses the revolving cutters F and plows B in the ground. The bolt'rod C, which goes through the back part of the beams, with sleeves D D between them, and which are screwed up with a tap on the left side, is to make its combination solid. The lever H, which is placed on the back part ofthe curved beams B, and the diagonal bar I, are constructed so as to raise all the revolving cutters F and plows B out of the ground at the same time. The standard O, which is placed on the back part of the frame, and having the ratchet, is

to regulate the revolving cutters F and plows B when the same are running in the grou'nd. If wanted to run deep, press down on the lever N, and set it in a certain notch on standard O, suitable to hold the revolving cutters F andplows B to the depth of the ground wanted. When it becomes necessary to turn, let the lever N loose, then bear down on the lever H, which will throw all the revolving cutters F and plows B out of the ground.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The plows ranged obliquely upon curved beams B, of graduated len gthand connected, at their rear ends, by rod C and sleeves D D, in combination with double loops E, revolving cutters F, frame A, and rod G, substantially as shown and described.v 2. The plow-beams and their connections, in

combination with the posts L, branched crossbar M, brake-lever N, and ratchet O, all arranged substantially as shown, and forv the purpose set forth.
