IMPROVEMENT IN WHEELE GULTEVATORS.

Specification forming part of Letters Patent No. IIHLEB MD, dated March 29, 1870.

To all whom it may concern:

Be it known that we, SoLoMoN H. DWIGHT and WILLIAM B. CHAMBERS, of Decatur, in the county of Macon and State of Illinois, have lnvented certain new and useful Improvements in Wheeled Cultivators; and we do hereby declare the following to be afull, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making apart of this specification, in which Figure 1 represents a perspective view of the cultivator and Fig. 2 represents a longitudinal vertical section taken through the same.

Similar letters of reference, where they ocour in the separate figures, denote like parts in both of the figures.

Our invention relates to the particular construction of the bolstered truck supported in and carried by apair of wheels, and the manner of arranging and uniting therewith the pair of lndependent cultivators, as will be explained, with the hinged guards annexed thereto.

To enable those skilled in the art to make and use our invention, we will proceed to descrlbe the same in connection with the drawings.

The truck or carriage frame is supported in a palr of wheels, A A, and is constructed substantially as follows: The journals a a, just inside of the heels of the hubs of the wheels that they respectively carry, are bent upward, as shown at b b, and flanged or recessed to receive the bent-up ends 0 c of the short horizontal bars (1 d, which, from their being at or near the line or plane of the journals, might be termed Fshort axles. The bars d d are adjustable on the bent ends of the journals, so as to raise the truck or carriage frame there on, or to lower it, as the case may be, and thus ra1se or lower the points of the cultivatorbeams attached to said bars. as will be hereinafter explained. I

At or near each end, respectively, of the pa r of bars dd, there are arranged bolsters c e e e, whlch support upon their elevated ends a quadrangular frame, f f f f, to which the tongue 9 and tongue-braces g are attached, and by whlch the machine is drawn and guided. The cultivator-beams BB are connected, respectively, to the bars (I d at the points 13 i, and maybe set to or from each other by means of ad ustable holes in said bars, and suitable uniting-irons, which allow said beams to move freely, not only horizontally but vertically and independent of each other. The joints at iallow of the horizontal and those at j j of the vertical movements of the said beams. The standards 0, that carry the cultivatorteeth or plows D, are placed fore and aft on opposite sides of their respective beams, and are braced, as at h, to said beams. The teeth or plows are fastened to the standards by a plate-ring and key. (Shown at 1 2 3 on the drawings.)

At or near the front end of each of the beams B B there is pivoted an angularly-bent and downwardly-inclined drag-bar, 70, each of which carries a guard of thin metal, E, which is set edgewise, and rounded or made of a runner form at its front, the rear ends of said guards being united to the standard by a chain, m, and hook a, so that they may be raised or lowered at pleasure. These guards run between the plows and the plants, and guard the latter from injury from or by the former. Each beam B has a single handle, F, attached to it and braced, as at 0, so that the two make a pair of handles, which the operator, who walks behind the machine, holds in his hands, and by which he guides and directs the teeth or plows along the rows of plants.

Projecting from the rear of the frame f there are two horns, p 19, upon each. one of which one of the beams can be thrown up, caught, and carried, as seen in Fig. 2, when the cultivator is being transported from field to field or from place to place.

The elevated frame f admits of the cultivation of plants that are very tall without interfering with or injuring them.

Having thus fully described our invention, what we claim therein as new, and desire to secure by Letters Patent, is-

' In combination with an elevated truckframe constructed and arranged as described, and supported and carried upon a pair of wheels, as herein stated, the pivoted beams 13 B, and the cultivator-teeth or plows, and independently-pivoted and suspended guards E. connected therewith, and arranged to be drawn by or carried on said elevated frame, as described.
