VILSON AGER, OF VASI-IINGTON, DISTRICT OF COLUMBIA.

Specification forming part of Petters Patent No. 92,556, dated July 13, 1869.

To a/ZZ whom it may concern.-

Be it known that I, WILsoN AGER, of l/Vashington, in the District of Columbia, have invented a new and useful Improvement in Decorticatingfllachines, and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings7 and to the letters of reference marked thereon.

In the accompanying drawings Figure 1 is' a side View of my machine for cleantnggrain. Fig. 2 is a longitudinal section of the same. Fig. 3 is detachedview of the end of the screen, showing the discharge-openings and slides, and also one of the grain-elevatorsv Fig. i is an end view of the machine; 1

yIn these drawings the outer case isnot represented. rihe case may -be of anyflsuitable ordinary construction.

My invention consists, first, in keeping the friction-surfaces of the machine cool, and also in separating and removing the dust from the grain, as fast as this dust or cutiele becomes loosened, by means of a blast of air passing through the machine; second, in the use of elevators to carry the grain from the lower part of the machine to the upper pant; third, in a continuous self-regulating feed and discharge by means of slides, and the consequent amount ofaction upon the grain; fourth, in a peculiar novel arrangement andconstruction of the machine; iifth, in introducing the grain at or near one end of the screen and the blast at or near the opposite `cud ,ofi the machine. i i ,y l

In the construction of my improved `graincleaner, any suitable frame, A, may be employed. Upon this frame is placed ya horizontal shaft, l5, carrying two stones, C, and provided with two pulleys, D and lil, or, better, two gear-wheels. Upon the same shaft B is ascreen, F, having separate journals from those ofthe stones and main shaft, and a pulley or gear-wheel, G. Power is applied to the pulley or gear-wheel D, thus setting the shaft A, stones C, and pulley or gear-wheel E in motion*say about one hundred and eighty revolutions per minute. By means of the bands II and I and the pulleys or gear-wheels K, Il, and M a slower motionis transmitted to the serceu -say about thirty revolutions to the minute, or the screen may be revolved in zii.'

the opposite direction to the stones, if desired.

The grain is fed into the machine through the tube M and the hollow shaft of the screen, as indicated by arrows in black lines. Then the grain spreads over and between the stones C, being subjected to a powerful scouring action, wearing off the euticle, and thus speedily decorticating the grain. At the same time the elevators O carry the grain from the lower part of the screen and scatter the same over the stones C for renewed scouring. A oonstant blast of air is brought into the machine,

asindicated by arrows in red lines, or in any other suitable manner, to blow out of the machine all the separated cuticle and dust as soon as they are detached from the kernels. The rapidity of the operation depends upon the amount of the grain kept in the machine, 'and the consequent pressure of the weight of grain in the screen. Vhen the decortication is coms pleted, the grain is discharged .through the openings P, Fig. 3. These openings are provided with adjustable slides R, by means of which the grain is made to discharge nearer to or at a greater distance from the shaft B at pleasure.

My machine is well adapted to deeorticat ing wheat and rye and all kinds of grain.

I do not limit my invention to the precise form above described, and I propose to use any number of stones that may be found advantageous, according to the kind of grain to be cleaned. i

I am aware that one or more stones have been inclosed in a cylindrical screen revolving on a horizontal shaft, and that a blast of air has been employed in .ricehullers to cool the grain and keep it from packing with the dust into a sort of cake or adhesive mass.

Having thus fully described my invention, I claim- 1. 'Ihe combination of the stones, the screen, and the grain-elevators F, or the equivalents of said devices, substantially as set forth.

2. The stones, the screen, and the grain-elevators, or their equivalents, in combination with a blast of air, substantially as set forth.

3. So arranging the machine that the weight of the grain kept within the screen will regulate the amount of scouring, or the extent t0 which the kernels are deeorticated, substantially as set forth.
