IMPROVEMELI T IN CULTIVA'IORS.

The Schedule referred to in these LettersPatent and making part'of the same.

To all whom it may concern:

Be it known that I, ROBERT D. CRAFT, of La Porte, in the county of La Porte, in the State of Indiana, have invented a new and useful Improvement in (Jultivators; and I do hereby declare that the'following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which-..

. Figure 1 is a perspective view, and

Figure 2 is a side elevation.

My improvement relates to the class of cultivators which is drawn by two horses, and the points on which I have made my improvements on former machines, will appear from the claims hereinafter to be set forth. I

In the drawings- AA are the side-rails of the frame, to which are attached the top cross-pieces B B, and the lower crosspieces 0 O of the frame, by the bolts. f f f f.

D is the tongue, the but-end of which is attached between the rear cross-pieces B and 0, and is passed between the .front cross-pieces B and G, and held in its place by bolts.

E E E E are the shovels, which are made fast to the beams a c a a by bolts, in such a manner that they scrape between the rows of corn, cleaning out all the weeds, and loosening the ground next to the hills of corn.

1) are the rods attached to the beams c a a a, and to the lower cross-pieces O G, and tongue D, and brace the same from each way.

c c are the braces which are attached on the outside of the beams on a a a, and to the back end of the siderails A Awith bolts, in such a manner that they brace the beams a a a a.

of which handles, F F,'the cultivator is guided and shifted about at pleasure.

When desired, the forward shovels maybe thrown nearer together by removing the bolts b b, and pressing in the front end of the side-rails A A, and by replacing the bolts 12 11 outside thereof, the shovels E E are held secure at any distance apart desired.

When desired, the shovels may be thrown in such a manner that they run deeper, by loosening the bolt on the back of the beams 00 a, and dropping the'points of shovels down, and so may be adjusted in any manner desired.

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

The side-rails'A A, cross-piecesB B, O G, tongue D, shovels E E E E, rods 1;, braces c c, brace G, and adjuster 0, respectively constructed and arranged, substantially as set forth.

In testimony whereof, I have signed my name to- ROBERT D. CRAFT.
