tion, reference being had therein to the accompanying drawings.

This invention pertains to certain new and" useful improvements in cultivators, being an improvement on the construction shown and described in Letters Patent No. granted to me January 29, 1889; and it comprises the details of construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved cultivator. Fig. 2 is a side elevation. Fig. 3 is a vertical cross-sectional view on the line 00 m, Fig. 1. Fig. 4 is a detail perspective view.

Referring to the drawings, A designates the sled or cultivator frame composed of two runners a a, adj ustably connected together by transverse bars a through slots a in which are passed nutted bolts a The runners are provided'on their lower edges with steel plates a and at their forward ends with opposite outwardly-curved arms a for proper guidance of the corn. the runners a are secured the inner "ends of divergent knives a a as shown. The transverse bars a are connected at their centers by a.bar B, upon a post I) of which is secured the drivers seat I). The knives a are made of thin spring metal, so that they can spring and adjust themselves to any listed furrows,

and conform to inequalities in the earths surface. These knives are also self-sharpeners, since they wear from the under side.

0 is a frame composed of one cross-bar and two end bars d d, to which are adj ustably secured leveling-arms D D. This frame is pivotally secured to frame A by hinges d, attached thereto and to the rear transverse bar a. A foot or hand lever E is secured at its rear end to frame 0, and is projected between a plate 6 and post I), to which and bar I) said plate is secured. This plate has a series of apertures, through which a pin 6 is inserted to hold the frame at any angle. The

Between the plates or and :runners a similarly to that described in my before-mentioned patent.

G G are the cultivator drag-bars, having rear pivoted sections 9 g. The forward ends of said drag-bars are bent at right angles and inserted through coincident apertures g of runners a. Upon these drag-bars are secured adjustable collars having hooks' 9 to which are secured chains 9 the forward ends of said chains being connected to bails g of the front transverse bar a. By means of these chains and collars the drag-bars can be held at any desired point, and can also be readily elevated and caused to-rest on the front bar a.

The advantages of my invention will be at once apparent, and it will be particularly observed that by means of the pivoted frame and foot-lever the operator can readily and easily raise and lower the levelingarms to any desired point.

I claim as my invention- 1. As an improvement in cultivators, the combination, with the main frame having the transverse bars, of the rear frame pivotally secured to one of said bars and having rearwardly=projecting arms, and the leveling of the rear frame pivotally secured thereto and carrying the leveling-arms, the foot-lever secured to said rear frame, and the means for securing the same, substantially as set forth.

3. The combination, with the main frame, of the drag-bars having their forward ends secured thereto, the adjustable collars on said drag-bars provided with hooks, and the chains connected to said hooks and to said main frame, substantially as set forth.

In testimony whereof I aihx my signature in presence of two witnesses.

WILLIAM H. FULLER.
