IMPROVEMENT IN GRAIN-SCREENS.

Specification forming part of Letters Patent No. 58,050, dated September 1S, 1366.

To all whom it may concern:

Be it known that I, C. F. BAYLOR, of Trenton, in the count-y of Mercer and State ot' New Jersey, have invented a new and useful Improvement in GrainlScreens; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation ofthe same, sufficient to enable one skilled in the art to which the invention appertains to make use of it, reference being had to the accompanying drawings, which are made a part of this specification, and in which- 4Irigure l is a plan of my improved graincleaner, and Fig. 2 is a vertical longitudinal section of the same, the line .fr x, Fig. l, indicating the plane ot' section.

Similar letters of reference indicate correspondin g parts in the two gures.

The subject ot' my invention consists ot' two sieves placed one above the other, joined together at an angle, and communicating with Aeach other through conductors which are situated at the lower end of the upper screen, and transfer the grain from the latter to the lower screen, thereby separating the grain from the screenings and trash which fall through the upper screen onto a chute or conducting-board, whereby'the screenings, &c., are deposited into a receptacle, which also receives the matter which is sifted through the lower screen.

In order that others skilled'in the art to which my said invention appertains may be enabled to fully understand and u`se the same, I will proceed to describe it in connection with the accompanying drawings.

A B represent two sieves fixed within suitable frames, which are joined together at an angle of thirty degrees, (more or less,) as represented in Fig. 2. These sieves are to be mounted on the ordinary tanning-mill Vat the end opposite from that at which the hopper is located, and they may receive a shaking reciprocating motion from any suitable actuating devices.

C is an intervening chute or conductingboard, which receives the foul matter as it is sifted through the upper sieve, and discharges such matter through the oblong opening D into a receptacle beneath.

E E are conductors, which are situated at the lower end ot' the sieve A, inside of frame A', and serve to conduct the good grain from the upper to the lower sieve.

The operation will be readily understood.

The grain to be cleaned is received upon the sieve A at the upper end thereof, and as it iows down upon the same the screenings, cockle, and trash fall through its meshes, and are deposited into the chtite orV conducting-board C, whence they pass through the oblong openings D at the lower end ot" sieve B and into the box which is placed Abeneath the sieves to receive the screenings, &c. The good grain, being too large to pass through the meshes of the sieve A, flows to the lower end ot' the same, and passes through the conductors E E and into the lower sieve, B, together with any trash or screenings which may not have sit'ted through the upper sieve.

On the sieve B the grain travels in a direction contrary to that in which it moved upon the upper sieve, A, and the sieve B sifts out the remaining screenings and trash, and discharges the good clean grain into its special receptacle.

rlhe upward-proiecting sides of the frame A prevent the grain from getting oft' the Sieve A otherwise than by passing through the conductors E, and the screenings, trash, &c., which are discharged through the lower sieve, B, enter the same receptacle as the matter which is discharged from the chute C through the oblong opening I).

Having thus described my invention, the following' is what I claim as new herein and desire to secure by Letters Patent:

rlhe combination, with the sieves A B and chtite or conducting board C, of' the con ductors E E, all arranged to operate in the manner and for the purpose herein set forth.

The above specitication of my invention signed by me this 24th day of July, 1866.

C. F. BAYLOR.
