To all wkont t r11/ay concern:

Be it known that I, WILLIAM H. FULLER, a citizen of the United States, residing at Bladen, in the county of Webster and State of Nebraska, have invented certain new and useful Improvements in Oultivators; and I do hereby 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention pertains to certain new and useful improvements in cultivators, being an improvement on the construction shown and described in Letters Patent No. 397,705, 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 Inyimproved cultivator. Fig. 2 is a side elevation. Fig. 3 is a vertical sectional view on the line m a', Fig. l. 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,throu gh slots a2 iu which are passed nut-ted bolts a3. The draft-horses are attached to the front bar a. The runlners are provided on their lower edges with steel plates a4, and atthe'ir forward ends with opposite outwardly-curved arms 0.5 for proper guidance of the corn. Between the plates a5 and the runners a are secured the inner ends of divergent knives a a6, as shown. The transverse bars a are connected at theircenters by a bar B, upon a post b of which is secured the drivers seat Z3. The knives a are made ,of thin spring metal, so that they can spring and ad just themselves to any listed furrows, and conform to inequalities in the earths surface. These knives are also seltsharpeners, since they wear from the under side.

C is a frame composed of one cross-bar and two end bars el d, to which are adj ustablysecured 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 F. is secured at its rear end to frame C, and is projected between a plate e and post h, to which and bar B said plate is secured. This plate has a series of apertures, through which a pin e is inserted to hold the frame at any angle. The leveling-arms D have each a single strengthening-piece d2 secured to its outer side by bolts or rivets D3, while the outer longer arms D have two such strengthening-pieces DL similarly secured. A shield F, having an adjustable barf, is secured to the rear end of runners a similarly to that described in my before-mentioned patent.

G G are the cultivator drag-bars, having rear pivoted sections g 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 vadjustable collars g2, having hooks g3, to

which are secured the ends of a chain or chains vg4, the forward ends of said chains being connected to a bail g5 of frame C. By means of these chains and collars and lever E the dragbars can be held at any desired point, and can also be readily elevated and caused t0 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 leveling-arms and drag-bars to any desired point.

I claim as my invention 1. As an improvement in cultivators, the combination, with t-he main frame having the transverse bars, of the rear frame pivotally secured to one of said bars and having rearwardly-projecting arms, and the levelingarms adjustably secured thereto, substantially as set forth.

2. The combination, with the Inain frame, of the rear frame pivotally secured thereto and carrying the leveling-arms, the foot-lever secured to said rear frame, and the means for In tostimonywheroof I afx my signature in securing the same, substantially as set forth. presence of two Witnesses.

3. The combination, with the main frame, of the drag-bars having their forward ends VILLIAM H'. FULLER. 5 secured thereto, the adjustable collars on said drag-bars provided with hooks, and the chains N/Ttllesses: connected lto Said hooks, substantially as set F. W. MCLAUGHLIN,
