IMPROVEMENT m CORN-SHELLERS, ac'.

The Schedule referred to in these Letters Patent and part of the same.

1'0 all whomjt mag concern; I a Be it known thatI, GEORGE S. COLEMAN, of A1- exandria, county of Alexandria and State of Virginia, have invented an Improved Oorn-Sheller with Oieaner and Elevator Combined, a-ndI do hereby declare the following to be anexact description therc of, reference being had to the accompanying drawing andto the -letters of reference marked thereon mak-,

. Thenaturc of my invention-consists in the constructiou. and use of cast-iron sieves for screening corn orothergrains; also the modcof tightening the elfevator, and the combination of the screens andclcvator with the corn-sheller. v

.To enable others skillcdiii the art to make and use myinventionfI will proceed to describe its'construction and -operation, asfollows:

A represents the sq'uare'upright frame,

a a B, the feeding-spout, into which thecars of corn are put, to'be shelled by the picker whcels G D, common to corn-shelters. g

E is au ordinaryfly-wheel, to be attacl,|cd,-of any re uired size to suit the machine.

Fisth'e main driving-crank,- by which the-gearing G'G are the elevators, by which the grain is carried up to the discharge-spout H,ywhere it is dis-..

charged him abox or bags at one end of the machinefi p J J are projecting arms, with ho'oks,for the purpose of suspending bags to catch the grain' as it is jdischargedl' a a i The elevators are attached to the upfightrevolvmg cued, as required,by m eans of nuts and screwsR 1,

p having an eye,-R,at the upper end, in which the journals of theroller N revolve, (the journals being adjusted. up or down in a'fvertical slot in the frame,) and hy tighteningFOr looseningthe nuts 1 P, the

roller is raised'or drawhfdowmso as to tighten or loosenthe belt.

KK are castiron sieves, that- 'ibratc by means of belt I], that revolves on a roller, M,abovc, and a 1 roller,N,belowi V r The lower roller is regulated, tightcncdfoi loosthe vibrating roller S, and its cranli' T, .and.eonnecting-rod' U. p

. 'lwo upright rods, V, attached-t0 the roller S, support-the upper sieve K and thelower sieve K isattached to the under side of the upper sieve by hooks W.

, The upper cast-iron siege ',K is perforated with larger apertures than the 'lower sieve K, and the sievesiK K,beinginad-"of cast-iron,sift the grain, &c., more completely and rapidly than wooden or gauze -rwire sieves,. the grain, 8E0. sliding quicker has a tendency to hold the grain-longer on the surface, doing less work.-

X is an inclin'el'board, that prevents the cobs from working back to the rear of the upper sieve K, and the oppositcincline board has a brushyY, on its end, to brush the-grain back onto the sieve.

'Ehcobsirrc discharged at one-end of the upper sive l'iat' Z, and the grain or corn passes through 'Lthe upper sieve K onto the lower sieve, that carries 't to the clevatorL.

lower sieveinto'a box beneath.

I purpose using my cast-iron sieves i'or sifting and cleaning corn,'or any kind of seeds, by having the sieves cast with larger or smaller apertures, to suit the size of the grain or seed to be cleaned.

' Iiintend to operate my machine by the crank 1*, or a band-pulley.

"The toothed wheel a o l-the main crank-shaft drives a. pinion, I), attached to the fiy-wheel E, and the belt Oconuects and operates the pulleys d (I, that drive the elevator L.

' At'the same time the rod connects the fly-wheel.

shaft, (on the opposite side of the machine,) so as to vibrate the roller S and sieves K K. The cast-iron sieves K K .last as long as the machine, while the sheet-iron sieves soon wear out.

Another advantage of the cast-iron is, that it al-. ways remains smooth, and will not rustor corrode like the sheet-iron, while the sheet iron corrodes in the grain and chaff from 1ron.z v

The cast-iron does one third more workthan the other sieves.

What I claim as my invention, byLetters Patent, is- -1. The combination and arrangement of the rollers a b and brushes :1: with the cast-iron sieves K 'K, hinged together at "W, when all these parts are constructed and operating as herein described, andfor the purposes set forth;

2. The arrangement with the above, the. elevator 'L, provided with adjustable bearing N, and eye-bolts sitting as rapidly as the castand' desire. to secure forth.
