UNITED STATES PATENT OFFICE ALEXANDER HEARST, OF PEORIA, ILLINOIS.

IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 120,643, dated November 7, 1871.

To all whom it may concern:

Be it known that I, ALEXANDER HEARsT, of the city of Peoria, in the county of Peoria, and in the State of Illinois, have invented a new and useful Improvement in Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making apart of this specification, in which like letters of reference refer to like parts, and in which- Figure l represents a longitudinal sectional elevation, Fig. 2, a plan, with seat and upper part of brace, on which the latter rests, removed.

Like letters in both figures of the drawing indicate like parts.

This invention consists in the addition of an auxiliary lever with a sliding fulcrum, placed above and jointed to the usual lever for raising or lowering the runners, 85o., the object being to afford a more eective means of operating the lower lever both in depressing it and forcing the runners into the soil, and also in permanently holding the said lower lever when the latter is depressed and the runners are required to be raised from the soil.

A is the usual frame, mounted on the aXle B supporting the seat and lever-brace H; C, the bar to which the seed-boxes and shanks of runners are attached, and to which the frame D E F, carrying the tongue G, is attached. E is the rear transverse bar of the latter frame, and which carries the brace h, to which is pivoted the forward end of the usual lever I for elevating or lowering the said frame C D E F, seed-boxes, and runners 7c. The said lever has its fulcrum in the pivot f, at the base ofthe seat and lever-brace H, passing to the rear through the vertical slot in the latter, and at this end carries the usual foot-board e, to which or to the adjoining part of the lever is pivoted at b the auxiliaryT lever K, the subject of this specification. The lever is about two feet in length, and lies in the same line as that of v lever I, in the upper part of the same slot in the seat-brace H, its middle portion merely resting on a pin, a, in said slot, but also having a notch, m, to retain it on the pin a when required. The lever K terminates in a foot-board, d, by which the feet of the driver may operate the lever.

The operation of this improvement is as follows: To throw the runners lo lower in passing hollows in the soil the feet are pressed upon the foot-board d of lever K, the lever sliding along the pin a, which operates powerfully on the lever I in forcing the runners down, and much more effectually than by the mere weight of the frame D E F, as formerly practiced, would do it. To raise the runners out of the soil the feet are pressed on the board e on the rear of the lever I; the depression of this end, which is pivoted to the lever K, draws the latter lever back until the notch on embraces the pin a, the seed-boxes with runners k and frame D E F being now raised, and thus held by the retention of the sliding-lever K on the pin a,- iu this position the machine with its runners elevated can be moved to or from the field without care or trouble. The dotted lines show the position of the levers and frames when the runners, 8mo., are thus raised; otherwise the drawing shows the machine with the runners in the soil.

Havin g thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

In a cornplanter, the auxiliary lever K provided with notch m and foot-board d, and pivoted to the rear end of lever I having foot-rest e, both levers being arranged to operate in the slot of brace H, in combination with pin a, substantially as shown and set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of August, 1870.

ALEXANDER HEARST.
