IMPROVEMENT IN WHEEL PLCWS. Q

Specification forming part of Letters Patent No. 122,442, dated January 2, 1872.

SPECIFICATION.

I, WILLIAM G. OnossLEY, of Apple River, in the county of J o Daviess and State of Illinois, have invented an Improved Gang-Plow, of which the following is a specification:

The present invention relates to an improvement on a combined sulkyplow and cultivator patented by me January 7, 1868; and its nature consists in the novel construction and combination of the devices hereinafter described and claimed.

In the drawing, Figure 1 is a longitudinal sectional elevation of my improved gan g-plow; Fig. 2, a plan or top view of the beams and their attachments; Fig. 3, a view of thefront' ends of the beams and the attachments which hold them in place when the plows are in opera-tion.

A B B B represent a framework, which is similar in construction to the patent referred to, and mounted on wheels Q in substantially the same manner, viz., by means of rackand pinion-framesg h, operated by levers b. Nothing new is therefore claimed in their regard.

In the present invention the plow-beams O D are made to have a simultaneous movement by means of short tie-beams F G, which are held in their respectiveplaces by means of screws or bolts j, ,Fig. 1, so that any tilting of either beam will give the other beam a corresponding movement, and, consequently, elevate or depress the plows E E equally. This arrangement is important, inasmuch as the beams are now controlled by a single lifting -1 and 4, and are thus brought down, so as to lower the draft and cause the plows to draw into the ground properly, and to overcome the tendency the plows have to raise up behind. This-arrangement is important, inasmuch as th'eplows are made to run very steadily and hold to their work so as to cut furrows of uniform depth without any unusual care on the part of the operator. The plow also operates with less strain on its several parts.- Another advantage consists in the-position of the pivotplates N, Figs. 1 and 4, which are placed on the under sides of the beams, and, consequently, cannot readily get loose, inasmuch as the beams rest thereon. These depending standards M are rigidly attached to plates L L, which are bolted to the rear side of the frame-piece B, several holes being made in said plates, so that theymay have any adjustment necessary to throw the plows .E to or from the land. The forward en ds of the beams are held in a fixed position when the plows are in operation by means of depending standards J J, which are rigidly fastened to plates K, secured to the middle frame piece B by bolts or otherwise, as most convenient. These standards project down onto the sides of the beams a little distance; and between them are secured short bars n a, Fig. 3, against which the plates P P, same figure, hear when the beams are in position, as shown at Fig. 1. By this means the beams are preventedfrom swing-- ing on the joints It, while at the same time the beams always have the same working position.

The device for raising and lowering the by dotted lines Z, the beams G D will be raised up,- a notch, d, in the back partof 0 being used to hold the lever Z in a fixed position when the plows are to be carried to or from a field. To hold the standards M firmly in place braces I are attached to them at R and fastened to the under sides of the plates K, thus keeping all of the parts firm as against the draft of the the plows. By placing the operating devices U Z cin front of the drivers seat 10 the lever T is always in reach of the driver and adjacent to the levers b, which raise and lower the framework.

Having thus described the construction and operation of my invention, What I claim, and desire to secure by Letters Patent of the United States, is-

The combination of the oentrallyadjustable guides M M with the depending laterally-adjustable standard J J, said standard being arranged to hold the forward ends of the beams O D in position when elevated, and leaving the same free when the plows are elevated, as set forth and shown.
