IMPROVEMENT IN CULTIVATORS.
Specification'forming part of Letters Patent No. 21,690, dated October 5, 1858.
To all 'u flwm it may concern:
Beit-known that I, B. S. MORGAN, of Delhi, in the county of Dela "are and State of Iowa, haveinvented a new and Improved Cultivator; 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 a part of this specification, in which-- Figure l is a side sectional view of my in- Fig. 2
is a plan or top View of same. Fig. 3 is a detached side view of one of the central shares,"
the frame of the machine being bisected, as shown at y y, Fig. 2.
Similar letters of reference indicate corre sponding parts in the several figures.
This invention consists in a peculiar arran gement of levers and share-stocks, as here inafter fully shown and described, whereby the shares may be raised above obstructions with the greatest facility, also allowed to yield or give to obstructions in case they are brought in contact with them, so that the parts cannot be injured thereby.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents a horizontal rectangular frame, which is supported by two wheels, B B. O is the draft-pole, and D is the drivers seat at the back part of the frame A. In the frame A, and at each side, two bars, E E, are pivoted, as shown at a, and to thebaek end of each bar E a curved or segment-shaped bar, F, is attached by a pivot, the latter serving as stocks for shares G, which are attached to their lower ends. In the lower part of each share-stock F a spring, a", isfitted, said springs being merely forked pieces of steel distended by their own elasticity and fitted in taper-recesses b in the stocks, as shown clearly in Fig. 1. The springs a are attached to rods H, con nected with the frame A, as shown clearly in Fig. 1. The bars E E are fitted between i011- gitudinal strips or bars 0 c of the frame A, as shown clearly in Fig. 2, and between said strips or bars and below the bars E E levers I I are placed and secured by fulcrum-pins d. To the back ends of the levers I I sockets e are attached to receive the bars E, and the front end of the levers, below their fulcrumpins (1, have triangular openings f made in them, as shown clearly in Fig. 1, and a link,
J, is fitted in each opening f,.the lower ends of the links being connected to a bar, K, the front ends of which are attached by pivots g to the frame A, as shown at h. To. the back ends of the bars K toothed rollers or colters L are attached. The bars K K, at each side of the frame A, are connected by cords i t' to the ends of a bar, M. These bars M are attached transversely to levers N at each side of the frame. (See Figs. 1 and 2.) O O are two bars, the front ends of which are attached by. universal hinges or jointsj to the front cross-bar of the frame A. To the back end of each bar 0 a curved or segmental stock, P, is attached, said stocks having each a share, Q, at its lower end. The stocks I? are grooved at their back ends, so that they may receive either of a series of projecting guide-plates, k, which are attached to a bar, R, in the frame A,just in front of the drivers seat D, as shown in Figs. 2 and 3.
The operation is as follows: As the machine is drawn along, the shares Q, Q may be adjusted nearer together or farther apart, as occasion may requige, the universal jointsj j of the bars 0 0 permitting such movement, and the shares are secured in the desired position by fitting the stocks 1 on the proper guide-plate k on the bar It. The shares G of the stocks F are suddenly raised in caseobstacles lie in their path by raising the ends of the ievers N, and the shares G and colters L L are raised rapidly at the first movement-in consequence of the links J bearing against the front upper.
part of the edge of the openings f, the links gradually passing to the front parts of the openings, and the movement becoming gradually slower and the power increasing. The object of this movement is to clear obstacles with certainty, a quick movement at first being essential, as when a share is somewhat raised they will most generally clear themselves or pass overobst ructions-such as round ed rocks (bowlders) and the like-without difiiculty. In case, however, the shares Gr catch against obstacles, the stocks F will be only forced out or backward from the rods H, the strength of the springs a being overcome. The bars 0 0 being directly in front of the linksJ fitted in the triangular-shaped openings f in said levers, and attached to the colter bars K, which are connected to the levers 'N,substantially as and for the purpose set forth.
2. In combination with the above, the bracerods H, attached to the share-stocks F by means of the springs a", fitted in the recesses bin the-stocks, and arranged substantially as andfor the purpose set forth.
