IMPROVEMENT IN DOUBLE PLOWSL Specification forming part of Letters Patent No. 170,146, dated November 16, 1875; application filed September 18, 1875.

To all whom it may concern:

Be it known that I, SAM]... D. WILLIAMSON, of Milford in the county of Decatur and in the State of Indiana, have invented certain new and useful Improvements in" Double Corn- Plows; and do hereby declare that the following is a full,clear,and exact description thereof, reference being bad to the accompanyin'g drawings and to the letters of reference marked thereon, making a part of this specification. I

The nature of my invention consists in the peculiar construction and arrangement of the several parts of a cultivator, the peculiarities of which will be hereinafter more fully set forth.

In the accompanying drawings making part of this specification, Figure 1 represents a plan view of my machine Fig. 2, a side view of a portion of it, while the otherviews are detached sections of parts which will be described.

'In the figures. A represents the forward,

frame-piece of the cultivator, to which power is attached for drawing the same. 0 Oyrepresent two vertical metallic bars, which are secured in pairs near each end of the beam A, by means of the loop-bolts a a. D D represent metallic plates, which are secured to the back of the frame piece A, and which are provided with flanges c 0, between which the bars 0 0 lie and are held. The axles B are secured by suitable bolts to the lower ends of the bars 0 0. Upon the axles B are placed suitable wheels for carrying the forward part of the cultivator. F F represent the cultivator-beams, which connect to a clevis, E, said clevis being secured by means of a bolt, d, to the bars 0 0. 61 represents a plate with flanges, which embrace one of the bars 0. This plate has a square hole in it to admit the square head of the bolt d. There are a series of holes in the bars 0 for the bolt 01, in order toallow the forward end of the plow-beam to be raised or lowered, as circumstances may require. K K represent the feet, to which the cultivator-blades are attached. These feet consist of metallic bars, which are bent at their lower ends, so that from this bend the other portions of the bar pass up parallel to the beam. They are connected to the beam by suitable bolts. Between the bars K and the beams are interposed the cylindrical blocks P, which said blocks have two flanges, between which the bars rest. 1?. n represent braces, which connect to the beams, and also to the barsK, for supporting said bars. L represents a metallic shoe, which rests on the front side of the bars K K, and against which the plow-blades rest. Suitable bolts pass through the blades, through the shoe, and then between the two parts of the bars K to confine said blades to the bars. These blades can be raised or lowered upon the foot-bars K K by raising and lowering the bolts in the opening between them. The shoe L has shoulders near its upper end, and on its face, against which the upper end of the plowblades rest. It also has flanges upon its sides, which embrace the bars of the foot to keepit in proper place. The handles G are bolted and braced on the beams in any convenient manner.

The two handles of the cultivators are connected together by means of the rods H H.

A rod is hinged or adjustably, connected to each handle, and then these two rods overlap each other, and are secured by means of a clamp, I, and set-screw J. The rods pass through the clamp, and the set-screw secures them in such a manner that the plows or cultiva-tors are stationed at a given distance apart, but in such a manner that each can rise or fall without affecting the working of the other. i

The distance of the front ends can be regulated by means of holes in the clevis E, so that I have a lateral adjustment both at front and rear.

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

1. The bars 0, bolted to the axles B, and secured to the frame-piece A by means of the flanged plate D, and the looped bolts a, all

constructed and arranged substantially as and v for the purpose set forth.

2. The shoe L provided with side flanges and stops at the top, against which the ploW-. hzwe hereunto set my hand this 27th day of share rests, in combinationwith "themetallio August, 1875. V

EQU-Shapdbalr K, and connecting-bolt, Wheref by the shoe earrying' the plow can be ad- SAMUEL WILLIAMSON justed up and down on the standard, asset Witnesses:

In testimony that I claim the foregoing I j GEORGE KENNEDY.
