IMPROVEMENT lNiGRAlN-CLEANER AND SEPARATOR.

Specification forming part of Letters Patent No. 12E/136, dated January 2, 1872.

To all whom 'it may concern:

Be it known that I, GEORGE S CARTER, ot" Lewisburg, in the county of Union and State of Pennsylvania, have invented a new and valuable Improvement in Grain-Cleaners; and I do herebydeclare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawing making a part of this specification, and to the letters and iigures otl reference marked thereon.

Figure l of the drawing is a representa-tion fof a vertical longitudinal section of my invention. Fig. 2 is an under-side plan view.

This invention has relation to grain-cleaners 5 and the novelty consists in the construction and improved arrangement of devices `for the purpose of vibrating' the grain-screens, as hereinafter described.

In theaccompanying drawing is shown the body and frame-work A of a grain-cleaning machine, supporting all the other parts. B represents the hopper, through which the grain is conveyed to the screens. C is'an inclined iioor, upon which the grain falls from the hopper and passes thence to the first screen l), which is inclosed within the laterally vibrating screen-frame D. The iloor C is also inclosed within or attached tothe screen-frame 1)', which is pivoted to the top of the case A, near its forward end, as shown at a, and sup' ported at its rear end by means oi' hingerods ai. E designates the fan-box, inclosing the rotary fan El, journaled transversely, the ends of its shaft E2 projecting beyond the sides ot' the case A.4 On one end of said shaft is placed a pinion, e, which engages with a spur-Wheel, e1, journaled to the upper part oi' the case A, andk operated by means of a crank-arm, c2, at tached to its shaft c@ The opposite end of the shaft E2 is armed with a crank, e4, holding one end of a pitma-n, F, the other end ot' which is pivoted to abell-crank, F', pivoted by means of a vertical pin between two brackets, j', pro4 Y jecting from the side ot' the case A, or arranged in any other suitable manner. To one arm 0f this bell-crank is attached a rod, j'f, which passes through the side of the case A, and is connected to the side of the screen -frame D. Hence, when the fan is rotated a lateral vibration is given to the screen-frame. G indicates a longitudinally vibrating or reciprocating screen-frame, provided with a screen, H, a-nd arranged underneath the screen-frame D in such a relation to it that the grain which falls from the iioor l of said screen-irame D shall fall on the screen H. The frames Gr and D/ may be provided with any desirable number oi" screens of diiierent kinds to separate the grain into its different qualities, 85o. After being screened by the screens inthe frame G the particles are conveyed through'the chutes or spouts g and 'opening gto the several apartments of the bin h.l I indicates a transverse sha-ft, having spindles which pass through the is given to the shaft I. This shaft has hinged to its lower side a bar. J, which extends length- .wise of the caseA, underneath the floor of the screen-frame G, to which it is secured. By means ot' this bar a reciprocating motion is given to the screen-frame G by the rocking ot' the sha-ft I. The rear end 'of the screen-frame Gis supported to the case A by means ot' a hinged arm or stirrup,k, on either side.

The armsof the bell-crank F and the arm I1 are perforated, so that their connections may be adjusted to vary the. motions of the screen- 4 Witnesses:
