RICHARD I'IAYIVOCD WEBB, OF MURPHY, TEXAS.

CORN-PLANTER.

SPECIFICATION forming part Of Letters :Patent N0. 612,938, dated October 25, 1898. Application led May 5, 1898. Serial llo. 679,830. (No model To @ZZ whom it may concern:

Be it known that i, RICHARD IIAYWooD WEBB, a citizen of the United States, residing at Murphy, in the county of Collin and State of Texas, have invented certain new and useful Improvements in Corn-Planters; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of4 this specification.

This invention relates to new Vand useful improvements in planters, and particularly to the construction of a planter having a pivoted frame carrying a skeleton wheel and seedboX, the ends of the skeleton wheel adapted to engage in the ground at intervals for the purpose of actuating the dropping mechanism in the seed-cup. In connection with the skeleton wheels are provided extensions whereby different-width rows may be planted by the adjustment of said extensions on the arms of the skeleton wheels. r

To these ends and to such others as the invention may pertain the same consists, further, in the novel construction, combination, and adaptation of the parts, as will be hereinafter more fully described, and then spe cifically deiined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of Areference indicate like parts throughout the several views, in whichn Figure l is a perspective view of my improved planter, showing the :manner of its attachment to a cotton-planter frame. Fig. 2 is a vertical central sectional view through the seedbox. Figs. 3 and t are detail views showing the extension-block to one of the arms of the skeleton wheel.

Reference now being had to the details of the drawings by letter, A designates the frame of the planter, which has mounted at its forward end the wheel B on the spindle C, and the rear end of the said frame has thelegs D, and suitable handles E are secured to the frame and the legs, as shown. Pi'voted to the upper portions of the said legs, as at f, is the frame F, the forward free ends of the side `shown in the drawings.

strips of which are adapted to normally rest on the longitudinal strips of the frame A.

`The skeleton `wheels are fastened to the shaft I'I, which is journaled to the said frame, as at f. The skeleton wheels consist of two cross-strips II and are provided with a suitable brace h. The shaft has keyed thereto a bevel-pinion I, which meshes with a similar pinion I', fastened to the lower end of the stub-shaft J, which extends up through the bottom of the seedbox and through a washer K, which is secured to the rotary plate L, mounted on the bottom of the said seedbox. This rotary plate has a series of apertures Z', in which the seed is adapted to fall, and as one of the apertures comes in registration with an outlet-aperture Nin the bottom of the seedbox or the platform supporting the seedbox the seed will drop through the spout C into the trough Q and thence to the ground.

When it is desired to lengthen the arms of the skeleton wheels, the adjustable blocks R are provided, which blocks are longitudinally slotted, as at R', and are held one to each arm of the skeleton wheel by means of a bolt T, carried in an aperture in the skeleton-wheel arm. Suitable clips U guide and assist in holding the adj usting-blocks on the arms, as In order to prevent the arms of the skeleton wheel from slipping, it is my purpose to attach to the arms metallic ends W, which will cut into the soil, as will be readily understood.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

In combination with the frame and legs thereon, and frame pivoted to said legs, the operating shaft journaled in the pivoted frame, the skeleton wheels, mounted on the said shaft, and made up of cross-strips H with brace-hoops, the adjustable slotted blocks R carried on the strips I-I, clips U secured to the blocks and having their ends inwardly bent to t over the strips, and metallic angle ends W, all substantially as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
