IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 183,912, dated October 31, 1876; application filed August 19, 1875.

To all whom t't may concern Be it known that I, AUSTIN C. EVANS, of Delphes, in the county of Van Wirt and State of Ohio, have invented new and useful lmprovements in Corn-Planters, of which the following is a specilication My present invention relates to certain improvements, to be hereinafter designated, upon the machine heretofore patented by me.

In the annexed drawings, making part of this specification, Figure 1 is a side elevation. Fig. 2 is a plan view, partly in section. Fig. 3 is a perspective view of the scraperfor cleaning the driving-wheel. Fig. 4 is a perspective view of the brush. Fig. 5 is a plan view of the bottom plate of the hopper and the under side of the feed-wheel. Fig. 6 is a transverse vertical section of the feed wheel, bridge of bottom plate, and part of the hopper. Fig. 7 is an end elevation of the hopper.

The same letters are employed in all the figures in the designation of identical parts.

rlhe driving wheel A, frame B, handles O, shovel D, and feed-Wheel E are all constructed as in my said former Letters Patent, and therefore need no further description herein.

rIhe driving-wheel is fiat across its face, and to prevent the adhesion of earth, which would disturb the regula-r operation of the feeding mechanism, I attach a scraper, F, to the frame B, immediately in rear of the driving-Wheel, and in snch'relation thereto that its lower and sharpened edge will shave the adhering earth from the cylindrical face of the wheel. The hole F will permit the earth adhering to the wheel, and gathering between the wheel and the scraper, to fall out. The scraper is recessed on the ends, to receive the side pieces of the frame, and is held adjustably by the rod G, having a nut on the outer end, by which the side pieces may be made to compress the scraper.

Instead of closing the pipe H by a slide, as in my said former machine, I use a Hap-valve, H1, turning upon a pivot, and actuated by the rod and hand-lever H2. The cutter I is of the usual form, except that I connect it to the point of the shovel by means of a hook, I', passing through a slot in the point of' the shovel, where it is held by the elasticity of the blade of the cutter. This construction makes the cutter serve also as a brace for the lower end of the shovel.

I also modify the position of the brush K. Instead of using the brush in common use, I employ a square brush, held in a prismatic tube, K1, clamped to a rectangularty-grooved block, K2, as shown. This brush stands with one ot' its angles over the seed-holes, the diagonal axes of the brush being as nearly as possible in line with the row of holes. I have found that a brush of the afore-described construction and arrangement will more perfectly' perform its work than those in common use.

The shield L is bolted to the frame B, and covers the opening between the frame and the top of the ground-wheel, for the purpose of preventing the earth adhering to the wheel from falling into the driving-gearing.

The feed-Wheel is placed in an annular pla te, M, in the bottom ot' the hopper O. It supports a bridge, M, which carries the shaft of the feed-wheel, and is out away on its upper face, so that the cogs on the lower face of the feedwheel may pass. These cogs engage a Worm wheel on the shaft N, driven by a pinion engaging either series of the concentric cogs on the driving-wheel A. The feed-tube H is placed under one end of the bridge M to receive the falling grains. Openings are formed at O in the lower corner of the hopper over the feed-wheel, to enable chaff to work out and fall upon the ground.

Instead of having the rod which operates the valve H1 applied at the front end ot' the valve, so as to require a long sweeping movement to open the. valve, I attach the rod H2 to a lever, H3, on the rear end of the valve, and pivoted in the middle, so that a slight movement of the band will open the valve; and as the lever H4 is pivoted to the handle, the valve may be tripped without taking the hand from the handle, as the location of the pivots of levers H4 and H5 enables this movement t0 be controlled.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination with the driving-wheel and operative mechanism, the shield L, arranged in relation thereto and to the frame, substantially as set forth.

2. In combination with the driving-wlleel,

the scraper F, with opening F', the side pieces ot' the frame, clamping the recessed ends of the scraper, and clampingrod G, for adjustably confining the scraper in such relation to the Wheel that it will shave the mud from the wheel, and by means of the hole F' prevent its accumulation, substantially as set forth.

3. In combination with the valve Hl and its actuating-lever H3, the lever H4, pivoted to the handle, the rod H2, and lever H5, substantially as set forth.

4. In combination with the seed-wheel E, the sliding plate M, with an opening to receive the seedwheel,and a bridge to support its shaft,

formed to permit it to revolvelwithout interfering with the driving mechanism, substan- AUSTIN O. EVANS. Witnesses:
