IMPROVEMENT IN CULTIVATORS. *A

Specification forming part of Letters Patent No. 58,389, datedOctobcr 2, 1866.

To all whom t may concern:

Be it known that I, GEORGE W. DooLITTLn, of the city of Lincoln, county of Logan, and State of Illinois, have invented a new and Improved Corn and Cotton Uultivator; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in whichvFigure 1 is a top view; Fig. 2, al frontend View, and Fig. 3 a side elevation.

The frame of this machine is constructed of wood, and marked F in Fig. 1, where it is best shown that it is simply notched together and bolted where the timbers cross each other. b b show a part of a circle of wood which is bolted on the forward end of the frame, upon which the tongue T is fastened so as to turn readily upon the bolt aa, describing the circle d d, which is plated with iron and traversed by a friction-roller on the under side of the back end of the tongue.' The tongue is held down by a small friction-roller, (marked g in Fig. 3,) which traverses the under side of the circular plate d d, Fig. l.`

On the top side of the rear end of the tongue is notched and bolted iirmly the section J in Fig. l, upon either end of which. the light wooden rods B R are fastened. with a bolt acting as a hinge, which bolt-hinge fastening is duplicated on the rear end of the rods R B upon the straight wooden piece V, which is held by a bolt in its middle, which works through a plate of iron, which has a slot cut only large enough to allow the center bolt through the piece V to slide fore and aft about four inches, E.

The chains Xare hooked into the eyebolt at either end of V and into the foot-plates P.

By this combination it will beseen that the plowman when sitting on the scat l l, and placing his feet on the foot-plates P, will have easy and accurate control in guiding by pressing down one or the other of the foot-plates, as may be required, which operation draws the rods It backward or forward, placing the machine at will on any angle with the tongue that may be required.

Fig. 2 shows the shape of the plow-molds A, which are constructed out of the `usual slab plow-steel, and are first cut the shape of the ordinary Diamond plow 5 then before bending cut out the circle, as shown in Fig. 2. By this shape of mold is obtained a wide share with a draft so light that a furrow can be plowed to a very great depth without materially increasing the draft, and hence can be ea. sily drawn by two ordinary horses or mules, which are great objects much desired in the rich deep soil of the west, and have not jyet been accomplished by other devices.

The plows A may be easily changed to throw the earth to or from the row, and placed at any given distance therefrom that may be required, throwing a greater or less quantity of earth to the row.

The plow-shanks Z can be readily changed from a perpendicular angle to an oblique an4 gle, throwing the wing of the share down to n't any shape of ridge upon which cotton is always grown, thus rendering it an admirable cotton scraper and culti vator.

In Fig. 2 is eXhibiteda crooked irona-Xle, (marked S,) upon which the wheels W revolve, made similar to the ordinary cast-iron axle, but, in place of getting its entire strength or support at only one end, is supported at the other end by the brace marked N, Fig. 2, and bolted on the frame on either side of the wheels VV. (Best shown in Fig. l.)

In Fig. 2, too7 is shown the manner of forminga fulcrum, m, fastened to the seat Z l, by using the same iron which holds up the front end of the seat. (Marked o o.) B B exhibitfront end of plow-beams, which are as wide as the cut of the share makes, in the end of which is fastened the lever L, which runs back the entire length of the beam B, and bolted at the fulcrum Y in Fig. 3, connected by the cross-bar c in Fig. 2 5 and by means of a spring-latcl1,G,in Fig. 2, the end of the plow-beams can be raised or lowered any'required distance without stopping,

`and be firmly held in that position; and in addition to this convenience the lever K in Fig. 3, working up or down on the ratchet Q, can be set at any point upon the ratchet desired. Thus, by the iron rod J J, Fig. 3, the plows are lifted out of the ground when'desired, or the rear end of the beam raised or depressed at will, and held irmly at any point on the ratchet. The two plow-beams are con;

nected at their rear end by a bow of tire-iron, in which the iron rod J J, Fig. 3, is fastened.

The plow-molds are bolted on an iron shank, Z, which is made with a llange to receive the bolt, and is held forward by chains at any required position by lengthening or shortening the chains.

Fig. 3 exhibits an iron slot, r Ir', and its brace s s, to which the beams are fastened by passing a bolt through the slot r fr, end of beam and lever, and through the iron slot on the other side oi' the beam.

In Fig. 2 is exhibited the double-tree D and the perpendicular single-trees z', working on a hinge at F, and provided with a hook at the lower end to receive the sin gle-tree, to which the team is attached.

The open space I gives to the operator the advantage of seeing the row without the obstructions of parts of machines, which is too GEORGE W. DooLiTTLE. Vitnesses:

EDM. F. BROWN, J. B. WOODRUFF.
