IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent N0. 36,945, dated November 18, 1862.

To all whom it may concern:

Be it known that. I, JOHN L. ELLIS, of Conoord, in the county of Morgan and State of Illinois, have invented a new and Improved Corn Plow or Cultivator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line as m, Fig. 2, Fig.2, a transverse vertical section of the same, taken in the line as 00, Fig. 1; Fig. 3, a horizontal section of a portion of the same, taken in the line I y, Fig. 2.

Simdar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel and improved construction of a corn plow or cultivator, as hereinafter fully shown and described, whereby the device may be drawn along and made to perform its work without breaking down or injuring the growing plants, and at the same time be capable of having its shovels or shares operated or adjusted at the will of the driver, so as to be elevated above the surface of the ground when necessary, as in turning the device at the ends of rows, and also capable of being moved while at work toward and from the plants, as circumstances may require.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents what may be termed the main frame of the machine, and is composed of two parallel side bars, a a, connected by two trans verse bars, B B, formed each of two parts, b c, the parts I) being straight and framed into the bars a a at right angles, and the parts 0 being bent upward at their centers, so as to be sufficiently elevated to pass over the plants without touching them. The ends or outer parts of e have a horizontal position, and are firmly bolted to the upper surfaces of the parts b, as shown in Fig. 2. The parts 0 of the transverse bars B are of metal. The other parts of the main frame may be of wood.

0 0 represent two rock-shafts, the journals of which are fitted in the parts I) of the transverse bars B, near the ends of the former. These rock-shafts are parallel with each other, and each has an upright, 1), attached to it at right angles. The upper ends of the uprights D D are connected by a cross-bar, E, the ends of which are provided with tenons d 01, said tenons passing loosely through mortises in the upper parts ofthe uprightsD and secured therein by pinsf.

To each rock-shaft O 0 there is attached a shovel or share, F, which may be of any suitable form, and to the lower end of each upright D there is attached a shield or guard, G, which is of curved form, the longitudinal section of a hollow cylinder. (See Figs. 1 and 2.) These shields or guards are at the inner sides of the shovels or shares F, and their concave surfaces face inward or toward each other, as shown clearly in Fig. 2.

H represents the draft-pole of the machine, the inner part of which is attached to the centers of the parts 0 of the transverse bars B B, and to the draft-pole the front end of a lever, 1,-is attached by apivot or joint connection of any suitable kind, said lever extending backward, so as to be over the drivers seat J, which is placed on two bars, K K, which are curved upward at their centers, so as to be as high as the upper parts of the parts 0 of the transverse bars B. The ends of the curved-bars K K are secured to two parallel bars, L L, the front ends of which are connected by pivots g to the back parts of the bars a a of the main frame A, and the front bar K has wheels M attached to its ends.

To the under side of the draft-pole H, at its back part, there is attached a double-tree, N, having a cord or chain, 0, secured to each end of it, and these cords or chains pass underneath pulleys P, attached to the front ends of the bars a a, each cord or chain having a whitfletree, Q, secured to its ends.

The operation is as follows: The device is drawn along directly over a row of plants, the horses walking in the spaces, one at each side of the row. The driver'from his seat J, by actuating the lever I, may move or swing the shovels or shares F and also the shields or guards G either to the right or left, in order that they may conform to the sinuosities of the rows, and the shovels or shares may be elevated entirely above the ground, when necessary, by the driver turning his weight back on the seat J, the front ends of the bars L L being thereby elevated, and consequently the main frame A.

To the back part of each bar a of the main frame A there is attached by a suitable standard a shovel or share, R, and these shovels or shares work between the rows of plants.

Having thus described my invention, what I claim as new, and desire to secured by Letters Patent, is-

The rock-shafts O G, uprights D D, connected at their upper ends by the bar E, and the lever I, said parts being applied to the main frame A, provided with curved transverse bars 13 B, in combination with the supplemental frame composed of the parallel bars L L and curved transverse bars KK, with the drivers seat J attached, the supplemental frame being mounted on wheels connected to the main frame, and all arranged to operate as and for the purpose set forth.
