GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 266,439, dated October 24, 1882. Application filed July 24,1882. (No model.)

To all whom it may concern Be it known that we, ENOS A. MORPHEW and HARRISON Wrrnnow, citizens of the United States, residing at Petersburg, in the county of Menard and State of Illinois, have invented certain new and useful Improvements in Grain-Drills; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same,reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to certain improvements in seed drills or planters; and it consists in certain features hereinafterdescribed, and specifically set forth in the claims.

Figure 1 is a longitudinal vertical section of a seed-planter provided with our improvements, and Fig. 2 is a detail view.

Like letters refer to like parts in both figures.

A represents the seed-box, suitably located upon and attached to the framework, from which depend the usual seed-conductors, B, which communicate with tubes O, to which are secured shoes 1). Each shoe is adjustably and yieldingly held in operative position by means goofa spring, E, secured to the toe thereof in any suitable manner, preferably removably, as shown, the spring being passed through a loop, (7, which, by means ofthe screws dd,is drawn tightly upon the shoe and acts to firmly clamp the spring, thus avoiding the necessity of perforating it for the passage therethrough of the screws. The upper-end of each springiscoiled once about a transverse shaft,F, suitablyjournaled in the framework, and is secured to the 0 under surface thereof by means of a screw or bolt, 0. If desired, a suitable clamp may be employed at this point, and thus all perforation of the spring can be avoided. Near one end of the shaft Fis secured alever, G, pro- 5 vided with a spring-pawl, 9, adapted to take into a notched sector, g, so as to adjustably retain the lever in desired positions at will. A similar lever, H, pawl h, and sector h are provided at the rear portion of the planter, said lever being secured to the axle I, orit may be to a beam through which the axle passes,said beam being loosely titted upon the axle, so as to turn thereon. To the axle is secured a series ofsprings, J J J J", &c., each located in rear of and in line with each shoe. These springs are secured to and coiled about the axle, as are the springs E about the shaft F, and each is curved down \vardl y and to the rear,

so that it may be pressed upon the ground.

In cross-section these springs may be concave, 6o convex, corrugated, or flat, as desired, as shown clearly in Fig. 2.

This being the construction, the operation is as follows: By throwing the free end of lever G to the front the shoe 1) is caused to bear upon the soil and penetrate the same,and itreadily accommodates itself to unevenness in the surface of the soil, and as the seed is dropped in the usual manner the springs J J, &c., are, by means of the lever II, depressed with such force or tension as to not only cover the seeds but to compress the earth thereupon, and this in a yielding manner, so that their pressure is practically uniform, notwithstanding the unevenness of the soil, and the result is that a uniform depth of covering-soil and a surer retention of the seed in line is accomplished,and less liability to disturbance of the seed by the action of the elements or otherwise, and nni-' formity of germination and growth are secured.

If desired, suitable guide-rods may be provided, to pass loosely through eyes on the tube 0, and secured to the frame-work above them to retain the shoe from longitudinal dis 8 placement.

Having thus dcscrihed'our invention and its operation, what we claim as new, and desire to secure by Letters Patent, is-

1: In a seed-planter, the shoes D, supported upon springs E, in combination with a shaft,

F, and leverG,adapted to be secured adjustably in desired positions at will, substantially as and for the purpose set forth.

2. The combination of the shoes D and the spring-coverers J, each adapted, substantially 5 as shown and described, to be yieldingly depressed and adjustably held in said depressed condition, substantially as and for the purpose set forth.
