ATTACHMENT FOR CORN PLANTERS.

SBEGIFIGATION formingpart of Letters Patent No. 723,857, dated March 31, 1903.

Application tiled August 2,190?- To all whom/ it may concern:

Be it known that we, ERNEST T. FRY, residing at Mount Jackson, and SAMUEL A. WINE, residing at Quicksburg, in the county of Shenandoah and State of Virginia, citizens 'of the United States, have invented certain new and useful Improvements in Attachments for Corn-Planters, of which the follow ing is a specification.

This invention relates generally to seedplanters, but especially to corn-planters, and has for its object to provide an improved attachment for such planters whereby the operation of'the planter is improved and its capacity increased.

With this object in view the invention consists, primarily, in an attachment to the cornplanter shoe in the form of an ordinary shovelplow blade slotted to straddle the shoe and yieldingly and adjust-ably held in position thereon. I

The invention further consists in the improved construction, arrangement, and combination of parts of such an attachment, which we will now proceed to fully describe and afterward specifically point out in the claims.

In the accompanying drawings, which illustrate our invention, Figure 1 is a perspective view of part of a corn-planter with our attachment thereon, the adj usting-lever, and holding pawl and rack being omitted. Fig. 2 is a partial view of a corn-planter in side elevation with our attachment thereon. Fig. 3 is a detail view of the shovel-plow blade in front elevation.

Like letters of reference mark the same parts in all the figures.

Referring to the'drawings by letters, A indicates the ordinary tongue of the forward part of the planter; B, a .clevis attached to the tongue in a well known manner, whereby it may be adjusted in height as may be desired; O, the main cross bar or beam, carried at the bottom of clevis B, and D D runners or shoes for making the furrows to receive the seed, one of said runners being secured in any suitable manner to each end of the crossbar C.

Mounted above the rear ends of the run- Seriall No. 118,123. (No modeL ners or shoes D D are seed-hoppers E E, of any suitable construction, from which chutes F F pass down through the rear portions of the shoes, whereby. the seed are dropped in the furrows made by the runners.

G indicates the ordinary coupling pole or beam of the rear portion of the planter, which rear portion is of any ordinary construction and not deemed necessary to fully illustrate,

"the coupling-pole being connected in any suitable manner with the tongue A.

In this instance we have shown the shoes or-runners D D connected with or secured upon the ends of cross-bar O by means of clips or sockets H H, to which clips are attached (or it may be formed thereon) bear ings or eyesI I, in which is journaled a. bar or shaft J, from which project at each end rearwardly and downwardly curved springbars K K, to the lower ends of which are secured shovel plow blades L L, which by means of central slots M M, extending from the points thereof upwardly, are straddled over the shoes or runners D D- From the central portion of the bar or shaft J projects upwardly an arm N, connected at its upper end by a rod 0 with a hand-lever P, pivoted at Q upon a bracket or casting R, secured to the coupling-pole G or other portion of the rear portion of the corn-planter in proximity t0 the drivers seat. By moving the hand-1e- :ver forward or backward the shaft or bar J is rocked and the shovel-blades L L raised or lowered on the shoes or runners D D, so that they may project below or occupy any desired position with relation thereto, the desired position being maintained by locking the handlever P by means of a curved rack S and pawl S (shown in dotted lines in Fig. 2) in a well-known manner.

In the operation of the invention the shovelblades serve to throw aside all chips, trash, litter, stones, hard lumps of earth, and the like out of the furrows made by the runners, thus leaving the earth in and beside of the furrows in better condition to receive the seed and facilitating and improving the operation of the coverers, which follow the shoes or runners. By yieldingly and adjustably mounting the shovel-blades liability of breakage by contact with obstructions is greatly lessened and the regulation of the height of the shovel-- blades with relation to the runners is always under the control of the driver, he being enabled to raise the blades entirely out of the ground when desired and to project them down to any desired depth.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. In a planter, the combination with the shoe, of a shovel-plow blade straddling the shoe, and means within easy reach of the driver for adjusting the blade vertically on the shoe, substantially as described.

2. In a planter, the combination with the shoe, of a shovel-plow blade yieldingly and adjustably mounted to straddle the shoe, substantially as described.

3. In a planter, the combination with the shoe, of a shaft, a spring-arm projecting rearwardly and downwardly therefrom, and a shovel-plow blade secured upon the end of said spring-arm and straddling the shoe, substantially as described.

4. In a planter, the combination with the shoe, of a rock-shaft, a spring-arm projecting therefrom, a shovel-plow blade on the end of the spring-arm straddling the shoe, and means for rocking the shaft whereby the blade may be adjusted on the shoe, substantially as described.

5. In a planter, the combination with the shoe, of a rock-shaft, a spring-arm projecting therefrom, a shovel-plow blade on the end of the spring-arm straddling the shoe, an arm projecting upwardly from the shaft, a pivoted hand-lever, a rod connecting the upwardly-projecting arm with the hand-lever, and means for securing the hand-lever in any desired adjustment, substantially as described.

6. The herein-described attachment for planters comprising the tongue, the main cross-bar, the clevis attaching them together, the shoes secured to the cross-bar, the rockshaft journaled on the cross-bar, the curved spring-arm at each end of the rock-shaft, the shovel-plow blades on the ends of the curved bars, and the means forrocking the shaft and securing it in any desired position, substantially as described.

In testimony whereof we aifix our signatures.
