SPECIFICATION forming part of Letters Patent No. 674,481, dated May 21 1901.

' Application filed January 31, 1901. Serial No. 45,462- 4(No model.)

T0 a/ZZ whom, t may concern:

Beit known that I, VIEGIL G. SKEEN, a citizen of the United States, residing at Wichita Falls, in the county of Wichita and State of Texas, have invented certain new and useful Improvements in Gultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in cnltivators.

The objects of the invention are, first, to provide swiveled carrying-Wheels which are under the direct control of the driver or voperator and may be turned at an angle to the line of draft to guide the machine, while at the same time maintaining the plows in proper position with reference to each other to the center of the frame and to the drill or row, thus preventing the plows from sliding off laterally and cutting too deeply at some points and skipping others, particularly on making a turn or cultivating curved rows, whereby uniformity of cultivation is insured; second, to provide a swiveled wheel attachment which may be applied to cultivators already in use; third, t'o provide an attachment of this character adapted for walking or riding cultivators, and, finally, to generally simplify andvimprove the construction -and increase the practical efficiency of cultivators of this character.

With these and other objects in view,which will appear as the nature of the invention is better understood, the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view in side elevation, of a cultivator embodying my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a rear end elevation. Fig. 4 is an enlarged detail perspective view of the beam and cooperating parts constituting my invention.

Like reference characters designate correspending parts throughout the several views.

A in the drawings represents the main transverse frame-beam of the cultivator, B the tongue or pole, C braces connecting the tongue to said beam, D a supporting-yoke supported by said ,tongue and braces and hav7 ing lateral arms d, E braces connecting said arms to the beam A, F the seat-supporting frame, G the doubletree or draft attachment, and H and I sets of links connecting the douL bletree to the arms d, all of which parts are embodied in cultivators now in common use. The parallel plow-beams 1 are also embodied in prior machines, but are constructed and mounted in a novel manner in my attachment, and hence constitute part of my invention.

In accordance with my invention the carrying-wheels 2 are mounted upon stub-axles 3, connected to vertical shafts Ll, swiveled in bearing-brackets 5 upon the ends of the beam A, which shafts are provided at their lower ends with right-angular and forwardly-extending foot portions 6. Through these foot portions and through the projecting upper ends of the shafts project substantially L- shaped bolts 7, which are provided at their upper and lower ends with securing-nuts 8 and 9 and serve to hold the said shafts in place and to brace said foot portions 6. By this construction it will be seen that the wheels 2 are swiveled to swing in arcs of circles in a plane parallel with the beams 1 to vary their angular position relative thereto.

The plow-beams l are pivotally connected at their forward ends, by means of bolts 10, to swiveled brackets or eyes ll on the arms d of the frame-yoke D, which bolts l0 are each adapted to engage one of a series of openings 12, formed in said brackets, whereby the beams are not only adapted to swing vertically to compensate for a yielding motion of the plows on striking an obstruction, but are also adapted to'swing in a direction transversely of the cultivator. The two beams are connected by means of a transverse yoke 14, having arms l5, provided with series of openings 16 to receive the coupling pins or clips 17 on said beams, whereby the beams are also connected to said yoke so as to be adjusted toward and from each other. In advance of the yoke the beams are further connected to the bolts 7 by links 18, whereby they are adapted to communicate motion to and swing simultaneously with the wheels. Each of these links 18 is adjustable as to IOO cultivation.

length, being composed of two sections having overlapping meeting ends united by bolts 18, so as to be adjusted to compensate for the adjustment of the beams 1 relatively to each other and to the said bolts 7. Stirrups or foot-rests 19 are arranged upon the beams 1 below and a short distance in advance of the drivers seat. To enable the driver to swing the beams and wheels from his seat, I connect the bolts 7 by means of a bar 22, which is adapted to be operated by a lever 23, pivoted at its forward end to the rear eX- tremity of the tongue B and provided at its rear end with a handle located so as to be readily accessible to the driver from his seat. By swinging this levell to one side or the other the wheels and beams may be turned in either direction in an obvious manner. The lever is held rigidly in position by a pawl thereon engaging a rack 24E on the main transverse beam A. If the cultivator be of the walking type, the beams may be provided with handles 20 for a similar purpose. To lock the beams and wheels rigidly against movement, pivoted bolts 26 are provided and have hooked ends 27 to engage the horizontal portions of the connecting bolts or rods 7.

Each beam 1 carries plows 21 and may coperate with the other to supporta central drill, (not shown,) according to the character of work to be done. Suitable levers 28 and connections are provided for elevating the said beams, and other operating devices may be arranged at points needed.

The parts shown in Fig. 4, with the exception of the beams 1, constitute an attachment which may be applied to existing machines which itis desired to equip with the invention.

The following advantages are secured by the use of my invention: The beams 1 can be guided to maintain the plows on either side of the rows or drill equidistant the one from the other and as near the row or drill as may be necessary for uniform and equal In other words, the swiveled wheels and beam may be swung so as to always keep the center of the cultivator over the drill or row and prevent the plows from cutting too much in one place and skipping another and from sliding off in Ia direction laterally of the row. The plows are also under the complete control of the driver or follower, as the cultivator is guided mainly by the beams instead of the tongue. The wheels are, furthermore, maintained equidistant from the drill or row, the use of a parallel movement obviated, as the beams are always equidistant from the drill and from each other, and the cultivator may be made to approach a fence or other obstruction much closer than cultivators of the usual construction.

The improvement is, in addition, a great advantage in turning or cultivating a curved row, for the above-noted and other obvious reasons.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of my invention will be readily understood without an extended description.

While the preferred embodiment of the invention is as herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction may be made Within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patentof the United States,
