IMPROVEMENT IN FANNING-MILLS.

Specification forming part of Letters Patent N o. 129,965, dated July 30, 1872.

Specification describing a new and Improved Fanning-Mill, invented by J AMES M. KENDALL and JAMES PEEL, of Madelia, in the county of Watonwan and State of Minnesota.

Our invention consists of a simple and etlicient arrangement of the shaking-shoe and a revolving screen, whereby the grain is iirst subjected to the blast in the shoe, and then passed through the screen, which is revolved by gearing connected with the fan-driving shaft, the said screen being protected from the bla-st of the fan by a hood. The invention also comprises a novel arrangement of the apparatus for shaking the shoe, whereby a horizontal and a vertical motion are imparted to the shoe. The invention also consists inconstructing the shoe with perforated sides, as hereinafter described.

'Figure 1 is a side elevation of our improved fanning-mill. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is a transverse sectional i elevation taken on the line ma; of Fig. 2. Fig. 4 shows the arrangement of the shaking apparatus.

Similar letters of reference indicate correspondin g parts.

A represents the shoe, with the ordinary coarse riddles B, onto which the grain is delivered from the hopper (l. The lower screen D of the shoe is made considerably shorter than in the mills as commonly arranged; and,

-besides slanting toward the fan, it also sla-nts from the left to the right side of the machine, and is iuclosed by the side pieces E and end piece F of screen-wire, except at the hole G, wherea spout, H, is arranged to extend from .the lowermost corner of said screen through the side of the case, and discharging into a spout, I, returning through the side of the machine into the screen K, arranged to eX tend through Vthe case from side to side, and discharge at L. Said screen is made smaller at the end'receiving the grain than at the other, in order to obtain sucient descent for the lower side for causing the grain to work through it and have the said receiving end as low as necessary to provide room for the screen-shoe above. This screen is fitted at the ends in the sides of the case for bearings to avoid the ordinary center shaft and journals. It is turned by a toothed rim, M, gearing with the wheel N on the crank-shaft O; but a belt and pulleys may be used instead of this gearing, if preferred. P represents a hood,- introduced between the fan and the screen to protect the latter from the fan-blast For shaking the shoe the cross-bar Q is con- `horizontal motion, and 1u order to' give the vertical motion the rod S is arranged to slant downward from the bell-crank to the point of connection with the cross-bar and to pass under a pin, W, and the bell-crank `is arranged to work in an inclined plane, so that the rod has a slight,rising-and-falling motion, whereby it lifts the shoe when coming up aga-inst the pin. The straps X, by which the shoe is suspended, are capable of springing readily to allow of the lifting of theshoe in this Way.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. The shoe A, provided with the perforated sides E E and end piece F, substantially as described.

2. Theshoe A, constructed as described,

and arranged with spouts H I and revolving screen K, substantially as herein shown.

3. The arrangement of the bell-crank R, rod S, bar Q, and the pin W, to impart vertical-as well as horizontal motion to the shoe, substantially as specied.
