IMPROVEM ENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 29,707, dated August 21, 1860.

To all whom it may concern:

Be it known that I, T. W. MoDILL, of Oquawka, inthe county of Henderson and State of Illinois, have invented a new and Improved Cultivator; and I do hereby declare that the following isafull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side sectional vicwof my invention,taken in the line as m, Fig. 2; Fig. 2, a plan or top view of the same.

Similar letters of reference indicate corre sponding parts in the twofigures.

The object of this invention is to obtain a cultivator which may be readily manipulated, or which may be attended and guided with but little labor. This result is obtained in consequence of provision being made for controlling the implement with facility by giving some of its plows an independent adjusting-movement independently of the draft-movement, whereby the implement may be kept in its proper course and obstructions readily passed over, the implement, also, by a very simple adjustment, admitting of being readily drawn from place to place.

The invention consists in a novel arrangement of adjustable shares, substantially as hereinafter described, whereby the desired end is attained.

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

A represents an axle, and B B wheels attached to the arms thereof. The central part of this axle is curved in bow form, as shown at a, in order that it may form no obstruction to the plants as the machine is drawn along.

To each end of the axle A there is attached a bar, I). These bars are parallel with each other, and are connected at their back ends by a cross-piece, c, which is also curved at its center in bow form, as shown at d, the bow 01 being in line with the bow at of the axle, the former being for the same purpose as thelatter. The front ends of the bars b have each a gooseneck, 0, attached to them by bolts j, which pass through oblong eyes 9 on the bars, and allow the goose-necks a certain degree of longitudinal play. The goose-necks e e are attached to a bar, h, which has the draft-pole B connected to it.

Through the axle A,at equal distances from each side of its center, there pass bolts it, both of which are shown in Fig. 2. The back ends of these bolts are provided with beads, and the bolts pass through clevises j j, attached to the front ends of bars k It. (See more particularly Fig. 1.) This mode of attaching the bars 70 k to the axloAadmits of the former having a lateraland turning-movement. Each bar I) has a handle, Z, attached to it, and also an upright, m, the latter being connected by traverse-bars n n, which are perforated at their ends and secured by pins 0, which pass through the uprights m. The back ends of the bars 70 it have each a pintle, 19, attached, and said pintles pass through loops or guides q g, which are attached to the cross-piece c, said guides being sufficientlylong to allow the bars k k a certain degree of lateral play or movement.

To each bar I) a plow-standard or foot, 'r, is attached bya bolt, 8, and the standards or feet are braced by rods t, which have jum-nuts u u on them-two on each-between which the standards or feet are placed. To the lower end of each foot or standard a plow, o, is attached. To each bar kthere is also attached a similar standard or foot, 20, the lower ends of which ha 'e plows a secured to them. The standards or feet 20 are braced by rods b, having jamnuts 0 on them.

From the above description it will'be seen that as the implement is drawn along the bars 76? 7c and plows a may be moved laterally, either to the right or left, and in case of the team moving either to the right or left, out of a proper course, the plows a may be kept in a direct line until the team is brought back to the proper place. In case, also, of the plows striking obstructions which may be in their path, they will be readily deflected or turned so as to pass over or by the obstruction. This arrangement of the bars 70 7c renders the ma nipulation of the implement very easy, greatly reducing the labor attending the use of the cultivator.

When necessary-as, for instance, in furrowing--the bars 70 k may be detached and the plows u only used. The depth of the plows o,

I do claim as new and desire to secure by Letters Patent V The arrangement of the axle A and bars I) b 70 7c and cross-piece 0 with the loose connection of the draft-pole B to the machine, substantially as and for the purposes set forth.
