IMPROVEMENT IN1 CULTIVTORS.

Specification forming part of Letters Patent No. 138,838, dated May 13, 1873; application filed March 24, 1873.

To all whom it may concern:

Be it known that I, DEWITT O. BAKER, of Fulton, in the county of Oswego and State of New York, have invented an Improved Cultivator; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making part of this specification.

Figure l being a top view of the cultivator; Fig. 2, a side view thereof; Figs. 3 and 4 views of parts detached.

Like letters designate corresponding parts in all ofthe figures. v

A single central beam, A, is used, guidehandles B B being secured thereto. One of the stocks C of the shovels or cultivator teeth is secured centrally under the beam A near the rear end, as shown, and held at its proper angle by a brace-rod, a. The other two shovel-stocks D D (three only being represented) are bolted at b b, respectively, to wings E E, which are made of iron swaged or bent into proper shape, as represented. They are hinged at c o to lianges d d, which are bolted to the sides of the beam. The swinging ends of the wing-irons are turned inward over the beam and lap over each other. They are provided with holes f f at regular intervals, by which they are fastened with a single bolt, g, to the beam. By employing different holes f f to receive the bolt g the wings are adjusted out or in, thus moving the shovel-stocks D D out or in correspondingly. In connection with these adjustable wings E E a crossbrace-bar, G, is used, to extend across from one stock, D, to the other, and it is bolted at h h to the two stocks. This brace-bar has transverse scallops or short bends or corrugations i i i swaged therein at regular intervals near its two ends, into which its two stocks, D D, iit when bolted to the arm. The holes Z l, through which the attaching-bolts h h pass are oblong-like slots lengthwise of the arm, as shown in Fig. 3. These oblong holes enable the stocks to be turned or canted in the cross corrugations or bends i t', and thus cause the shovels H H to incline inward or outward, in order to turn the earth inward toward vthe row of plants or outward therefrom, like mold-boards, or to be square across in relation to the beam A. Thus, if while the stocks are bolted to the cross-bar, as shown, the wings E E are adjusted outward, not only will the cultivator teeth or shovels H H be moved inward nearer to each other, but by loosening the bolts h h and turning the stocks a little in the corrugations the shovels will be canted inward, so as to throw the earth inward as the mold-board of a plow, and vice versa. The bolts kwh, which unite the stocks D D to the brace-bar may be eye-bolts to receive the ends of brace-rods 'm m, which are bolted to the forward ends of the beam A.

In order to adapt the shovels or cultivator teeth H H to the adjustments herein specilied their edges are beveled on the rear or under side, as shown in Fig. 4, in order that they may cut the earth properly. They are also iiat transversely to adapt their shape to the adjustment. The shovels H H may beinclined inward to a certain extent by having the front surfaces of the stocks D D beveled, as shown in Fig. 4.

By beveling the stocks so as to turn both the shovels inward, then on shifting the stocks interchangeably to opposite sides they incline the shovels outward. to the same extent. This mode of inclining the shovels may be used to increase the extent of inclination produced by the corrugated brace-bar, when a greater inclination is required than either means will eii'ect alone.

The wings E are represented so arranged as to place the two side shovels H H forward of the central shovel I. This arrangement may be reversed by reversing the hinged Wings E in position, which is eii'ected by shifting the hinge flanges d d to another set of holes, it n, through the beams and passing the bolt g, which secures the movable ends through a bolt-hole, p, in the top of the beam.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The corrugated brace-bar G, constructed and arranged in combination with the stocks D D, substantially as and for the purpose herein specified.
