FANNING-MILL.

SPECIFICATION forming part of Letters Patent No. 243,160, dated June 21, 1881.

Application filed March 29, 1881. (Model.)

1'0 a whom it may cancer-n:

Be it known that I, THOMAS R. Rosrnn, of Dayton, in the county of Columbia, Washington Territory, have invented certain new and useful Improvements in Fanning-Mills; and I do hereby declarc that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertans to make and use the same,reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side eleration of my improved fanningmill with sacking attachment connected thereto. Fig. 2 is a vertical lon gitudinal section of my mill. Fig. 3 is a horizontal section taken through the shoe;

This invention has reference to improvements in fanning-mills with means connected thereto for sacking the cleaned grain and it consists in the combination and arrangement of the parts, substantially as hereinafter more fully set forth and claimed.

Referring to the acconpanyin g drawings, A indicates a casing, within one end of which is hung the fan B, with its shaft provided with a pulley, a, and a gear-wheel, a', for imparting motion to the fan. The use of the pulley will be seen hereinafter. In the upper part of the casing A is the hopper b.

C is the shoe, hung within the opposite end of the casingA, with its sides adapted to play in openings in the sides of the casing, and supported by han gers c c, pivoted to the outside of the casing, to pernit it to have a vibrating or shaking motion.

D is a lever pivote'd in the inside of the case A, and extending transversely through and projecting a little beyond the outside of the casing, to enable it to be Conveniently connected by the pitnan d to the eccentric or gear'- driving wheel of the fan, by which motion may be imparted to the lever. This lever is connected by a spring-arin, d', to the shoe C, to transmit motion to the shoe, and by a rod, d to the lower set of sieves, to impart motion to the latter, but in a contrary direction to that of the shoe having the upper set of sieves.

Within the shoe is arranged the coarse gang of sieves E, to subject the grain to the first step in the cleaning process.

' the elevator-belt.

An inclined board,

E', is arranged under the shoe, to conduct the falling grain to and allow it to pass upon lower finer set of screeris or sieves below.` From the discharging or lower end of the board E', and from two cross-bars, e e, disposed at suitable intervals apart, and in the same inclination with the oppositely-inclined lower sieve or sievcs, dangle pieces of canvas, e' e 6 about touchin g the lower sieve, the object of which being to arrest the bounding motion of the elastic grains or seeds, and thus precipitate them with the other grain upon the sieve.

F is the lower sieve or set of sieves, with the sides of its frane adapted to move in grooves in the inside of the casingA in an oppostelyinclined plane to that of the shoe having the upper sieves. The grain is subjected to a second cleaning by being passed over this sieve or set of sieves to effect the thorough separation of the grain and cockle.

Arranged under the sieve F, and supported upon cross-pieces of the supportng-uprights of the casing A, is arack, Gr, composed of a series of edgewise boards, g, secured upon longitudinal parallel bars g', and with their upper edges placed in contact with the under side of the sieve F. This rack is to prevent the clogging of the sieve, and thus facilitate the cleaning process. y

His the sacking device, which consists of the base h, with its floor formed with a clute, h', and the elevator H', with the upper shaft of its endless bucket-belt provided with a pulley, h with a belt, h passing around the pulley a upon the fan-shaft to impart motion to The elevator-stock H' has a discharging-spout, h with opposite pins or studs, h upon its inside, near its outer end, to perniit of tle'slipping of the open end of the sack thereon in readiness to receive the elevated grain. A cover, h With a downwardlyprojecting lip, h' hinged upon the upper end of the elevator stock, is adapted to shut down upon the spout h and over the studs h and thus secure the sack thereon. The sacking device is adjusted to' the fanning-mill in the manner shown in Fig. 1, and hookcd thereto, as seen in the same figure.

I is a lever connected by an adjusting-screw, I', to the elevator-stock, and with a pulley in one end, over which passes the belt h The IOO lever I has a slot, i, through which the screw I' suitable Operating neohauism, as herein depasses, to permit of the adjustment of the lescribed, for the purpose set forth.

Ver so as to tighten or loosen the belt upon its I testimony that I claim the foregoing as pulleys, by which the elevator can be put in my own I have hereto affixed ny signature in 5 and out of operation, as may be desired. presence of two witnesses.

Having thus fully described nyinvention I claim and desire to secure by Letters Patents THOMAS ROSIER' The oombination of the frame A, the shoe G, Witnesses: the sieve-frame F, the elastic or spring bar d', J. S. THOMAS,

[o Secured to lever D, the conneotingrod d and T. B. W. WILLIAMS.
