UNITED STATES PATENT JAMES M. HOLLADAY, OF TWYMANS STORE, VIRGINIA.
IMPROVEMENT IN DOUBLE CULTIVATORS.
Specification forming part of Letters Patent No. 157,603, dated December 8, 1874; application filed October 23, 1874.
CASE A.
To all whom it may concern Be it known that 1, JAMES M. HOLLADAY, of Twymans Store, in the county of Spottsylvania and State of Virginia, have invented a new and Improved Double 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 drawing forming a part of this specification, in which Figure 1 is a longitudinal vertical sectional elevation. Figs. 2 and 3 are detail views of the crank-axle with devices for raising and lowering. Fig. 4 is a plan view with a portion broken away.
This invention relates to certain improvements in double cultivators. It consists in the peculiar construction of devices for adjusting the tongue or pole from the rear for the purpose of adapting the implement to hill-side cultivation, and also in the peculiar construction and arrangement of the parts of a traction-frame, so jointed and attached to the carriage as to admit of the cultivator proper bein g lifted from the ground and suspended about the axle for purposes of transportation, It consists further in the manner of pivoting the traction-frame, so as to adjust the cultivator laterally to the irregularities of the row, and to deep or shallow cultivation.
In the drawing, A represents a tongue, which is pivoted at a. to a frame, B, and provided with a rack, b, in the notches of which rests a catch, 0, attached to a rearwardly-extending lever, U. D is an intermediate lever attached to lever G by a spring and pivot at the rear end, and pivoted to the tongue near the middle. This arrangement enables the operator to adjust the tongue A to hill-side cultivation, by throwing it to the right or left, by simply depressing lever O and moving it laterally, the catch and rack holding the said tongue in the position desired. The draft,
thus being made slightly diagonal to the axle, prevents the tendency in the carriage to cross the row in its downward inclination. E and F are transverse bars, which support frame B, and are themselves supported upon the bracket-shaped pieces 61 and e, which latter are united at their lower extremities and supported by the crankaxle G. The vertical portion of said crank-axle is held securely upon a circular plate, f, by means of the strap 9 and screw h, which adjustment admits of the change of the crank-axle from a position below the hub z of the wheel to one above it, thus adapting the carriage to the more advanced stages of the tall growing crops, and to distant transportation over uneven surfaces. H are the traction-frames, which are horizontallypivoted at one end by a single bolt, j, to a clip, 70, adjustably attached to bar E by means of bolts whichpass through slots in the said clips. The object of this arrangement is to give the cultivator a lateral adjustment, the single pivot adapting the motion of the said cultivator to the irregularities of the row, and the slotted clip admitting of the lateral adjustment of the entire frame. Said frame H consists of the straight pieces I, and the arched pieces J, provided with the loops 1, and connected with pieces I by the standards K. Attached to standards K are the supports.
m, which rest upon the crank-axle G, and by being moved up or down upon the standards K adjust the frame H in a vertical direction for deep or shallow cultivation. L are clips upon the crank-axle, which are adjustable upon the same, and limit the lateral play of the traction-frames. M is a folding section, which is pivoted at one end to the lower extremity of the traction-frame, and at the other to a set of handles, N, the said'section and handles being intended to adapt the implement to receive a cultivator, O, which, as to construction, is more particularly described in a separate application of this same date. The said cultivator is pivoted about the middle to the rod connecting M and N, and has two pins or studs, n, which rest inside the arched pieces J.
The manipulation of the cultivators in connection with the carriage is as follows: When the implement is in operation the cultivators are upon the ground and drawn by means of the section M, the single bolt j allowing the frame H and cultivator a lateral play to adapt the cultivator to the irregularities of the row.
If it be desired to lift the cultivator from the ground to relieve it from accumulations of grass, or to avoid stumps or stones, this can be effected to great advantage by pressing forward the handles in an upward direction, which action lifts the cultivator with all the hoes immediately from the ground in a hori zontal position. This is effected by attaching the folding section M, through which the draft is exerted, to the central portions of the cultivator, and confining the movement of the front end of the cultivator to the arc of a circle by means of the studs n in the arched pieces J. If it be desired to disengage the cultivator e11- tirely from the ground, the handles are lifted and pushed forward until the studs n of the cultivator rest in the loops Z. The cultivator is then supported upon the sections M as upon a fulcrum, the leverage of the rear of the cultivator locking the studs 1 securely in the loops 1, thus obviating the possibility of its falling back.
Having thus described my invention, What I claim as new is- 1. The combination upon the frame B of the 3. The .combination of the studs 02 of the cultivator with the arched pieces J and loops 1, substantially as and for the purpose described.
4. The combination of the traction-frame H, the folding section M, the handles'N, and the cultivator O, substantially as and for the purpose described.
JAMES M. HOLLADAY.
