UNITED STAT S PATENT OFFICE HENRY SIDDALL, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN GP AlN-SEPARATORS.

Specification forming part of Letters Patent No. 37,362, dated January 6, 1663.

To all whom it may concern."

Be it known that I, HENRY SIDDALL, of the city and county of San Francisco, in the State of California, have invented a new and useful Machine for Separting and Cleaning Grain, entitled Siddalls Blast GraiuSepara- I tor and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of thisspecification, in whic Figure l is a perspective view with the side shown open. Fig. 2 is a sectional view, representing the machine cut through the center vertically and lengthwise. Fig. 3 is a vertical sectional view of the spouts A, B B B, and G. t

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Letter A represents the spout through which the grain passes into the machine, and is made elbow-shaped or angular, so that it may cause the grain to scatter and thereby effect an equal division of the same into spouts B which spouts are for distributing the grain throughout the breadth of spout G.

G is a spout through which the grain is introduced into the blast-spout F, and is placed at the side of said blast-spout, for the purpose of allowing the grain to fall from a given height and strike upon the bottom piece, D, thence bounding through opening E, and will thereby scatter throughout the whole area of. the blast-spout F.

F represents the blastspout in which the grain is cleaned by means of a current of air, which passes upward, carrying the refuse substances through opening G. The grain finds egress at S.

H is a blast-chamber. The smallest end of the same is attached to the blast-spout F, and is constructed with a gradual increase to a larger dimension at the other end, thereby causing the current of air to be reduced hence all the grain that is carried up by said blast will drop into chamber I, and the refuse matter, except such as dust and chaff, will fall into chambers L and 0.

I is a returning-chamber, situated under the blast-chamber H, for the purpose of catching the grain that is carried up through the openin g G, from whence it is returned. By the use of this returning-chamber a much stronger blast can be applied than otherwise.

L and O are chambers for catching the refuse matter. The heaviest of the same will drop into L, the lighter portion into 0.

K is a spout for transmitting the return grain from chamber I to the elevator W and X, and it is optional whether the same empties into the hopper V or the elevator.

J and M are hinged pieces forming adjustable partitions between chambers I, L, and O.

R is a suction-fan for generating a current of air in the blast-spout F.

V, the hopper, holds the grain previous to its passing into the machine. U, the slidegate, regulates the flow of grain from hopper V.

W is an elevator, in which are placed pulleys 1 and 2 and belt Y, to which are fastened cups X. The Whole of this apparatus is for carrying the grain upward.

Z represents ,the slide for regulating the current of air.

The elevator W X and the fan B may be driven in any convenient manner.

I introduce the grainintohopper V, and the flow therefrom is regulated by the slide-gate U, whence it is carried upward through elevator W by cups X, and is delivered into spout A, whereit'is equally divided by spouts B, and is distributed throughout the breadth of spout G, thence striking upon the bottom piece, D, thence bounding through the openingE, and is thereby scattered throughout the whole area .of the blast-spout F, and is fanned by a strong current of air or blast. The clean passes out at S, and may be gathered in any convenient manner. The refuse substances are carried up through the opeuin g G into blast-chamber H. Here a portion of grain is also carried up, which drops into the returning-chamber. I. A portion of the heaviest refuse matter will likewise fall into said chamber I, and this I call the return grain,

which is transmitted through spout K back to the elevator, whence it is carried up, thus passing through the machine again, at the same time and with the regular supply of grain, thus keeping a part of the grain continually returning. By this process I am enabled to effect a more thorough separation. The refuse substances are carried along the blast-chamber H, and the heaviest of the same will drop into chamber L, the lighter portion into 0. The dust and chaff is drawn into fan R, from whence it is blown into the open air. The refuse matter is extracted at the slides P and N.

What T claim as my invention, and desire to secure by Letters Patent, is-- 1. Spout A, provided with distributingspouts B, as described.

2. Spouts A O, placed relatively to blastspout F, When constructed and operating as described, and for the purpose set forth.

3. The arrangement of chamber 1, spout K, and elevator W X, for the purpose of returning a part of the grain, as herein set forth and described.

HENRY SIDDALL.
