SPECIFICATION forming part; of Letters Patent No. 375,719, dated December 27, 1887.

Application tiled October 14, 1887. Serial No. 252,316. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. VVYATT, a citizen of the United States ofAmerica, residing at Princeton, in the county of Caldwell and State of Kentucky, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to beafull, clear, and exact description of the invention, such aswillenable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part ofthis specification.

My invent-ion relates to an improvement in cultivators; and it consists in the novel con struction and arrangement of the parts thereof, which will be more fully hereinafter described, and pointed out in the claims.

The object of my invention is to provide a cultivator for use in the formation of hills for planting tobacco and other products requiring hills, the construction and operation thereof being simple and ettectivastrong and durable, easily handled, and readily understood. Iattain this object by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate similar parts in the several views, and in which- Figure 1 is a perspective view of my improvement. Fig. 2 is a longitudinal vertical section thereof.

B indicates the main beams, which diverge from their front meeting pointtoward the rear thereof, and have curved plows E secured thereto, which are mounted atan angle and inwardly toward each other. These plows are formed of such curvature that the soil will be thrown inward thereby and form a central ridge.

Supplemental beams C are secured to the beams .B and extend to the rear ofthe saidlatter beams and are provided with a series of apertures, c, at their rear portion. These beams() are constructed in the form as shown, converging at their front and rear portions and distended at their central portion. A pivot-rod, passes through the forward ends thereof and through the beams B and lower ends of the handles A. The rear portions of the said beams O are curved downwardly, and

at the upper beginning of said curve they are supported on a tie-rod, B, uniting the beams B at this point. The rear lower ends of the beams G are secured to the outside surface of two former plates or followers,F F,which have angle-plates fsecured thereto and projecting upward therefrom and form bearings for the shaft ofa roller, F, which is mounted between said plates F. These plates F are inclined outwardly, the space between the same being wider at their bottom than at their top portions. On the said beams 0 above the plates F a tie-brace, O, is mounted, which prevents the plates F from separating by strain brought to bear thereupon.

Secured to the rear sides of the plows E are irregular angular metallic strips D D, which extend inward and are secured to one set of the holes 0 of the beams C,and then extend upward and are secured to the handles A. The upper ends of the strips D are formed with a series of apertures, 07, so as to permit of a ver tical adjustment with the plow-handles, said strips being also adjustable with relation to the holes 0 in the beams C. By this means both a vertical and lateral adjustment of the parts as thus connected is readily obtainable, which would narrow the hillformed and to some eX- tent decrease the depth of cut of the plows E.

Between the front converging ends of the beams B a draft iron or link, G, is pivotally mounted, but clamped stationarily when the beams are joined, as hereinbefore described. The said link G is formed with a series of forward apertures, g, at dilierent elevations and is adapted to rest on a cross-pin, g,which holds and bracesit at an inclination. The rear of said link is also provided with an aperture, 9 which permits of a variation in its longitudinal adjustment. By attaching the link of the whiffletree in the lowermost aperture 9 the tendency will be to draw the plows deeper into the ground, and an upper adjustment of the whiiiletree-link will lessen this tendency.

In the use of my improvement the plows E turn the soil inward toward the center and the plates F press the sides of the ridge thus formed and slightly compact the same, and the top roller, F, rides over the top of the ridge and presses the same downward at the same time that the plates F press it upward.

The width between the plates F and the rear of the plates E is equal, and the width of the cutis uniform with the ridge formed. The advantages of my improvement consist in the simplicity of operation and positive re sult, the draft necessary being but the power ofa single animal. The cultivator can be used to advantage on hillsides and on irregular surfaces.

The simple construction of my improvement and its general utility being obviously apparent,it is unnecessary to further enlarge upon the same herein.

Having thus described my invention, what I claim as new is- 1. The combination of the plowbeams B, the curved plows E,secured thereto and set at inwardly-opposing angles, the supplemental beams G, pivoted to the beams B and having the rear tie-brace, O, the tie-rod B, the in clined plates F, having angular platesf, and the roller F between said plates and the strips D, said beams O and strips D being adjustable, as set forth, with the parts to which they are connected, substantially as described.

2. In a cultivator, the combination of the diverging plow-beams, the curved angularlyset plows, the supplemental adj ustable beams pivoted to the main diverging beams, the in- JOHN R. XVYATT.
