Letters Patent No. 101,514, dated April 5, 1870.

IMPROVEMENT IN PANNING-MILLS.

The Sehednle referred to in these Letters Patent and making part of the same.

useful Improvement in Fanning -Mills; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make andnse the same, reference being had to the accompanying drawings forming part of this specification.

This invention relates to improvements in fanning mills, and consists in the construction and arrangement of parts, as hereinafter specified.

The figure represents a longitudinal sectional elcvation of our improved fanning-mill.

A represents the inclined sides of the hopper, be-

i tween the lower edge of which is the throat B.

O isthe adjusting-slide or gate for regulating the opening of the throa It is arranged on the top of the upper sieve-shoe, and provided with slide-bars D, in one of which adjusting-screw E is arranged for moving it either wa. The said screw is provided with a hand-crank, F, for turning it. This arrangement of the gate on the shoe facilitates the delivery of the grain, in consequence of the motion imparted to it by the shoe.

G is the agitating-rod, bent at the ends to form vertical legs, whereby it is connected to the slide 0, so as to be supported above the throat in the hopper for agitating the grain, straw, and c-hafi' by the motion it derives from the movement of the slide 0, which works back and forth by the movement of the sieveshoe, which is eflected by the rock-shaft H, arm- I, and connecting-rod K.

The arrangement for grading the grain consists of the two long final sieves L M, and the tilting valve N.

The sieve L is made large in the meshes, to retain only the largest grains, which are delivered out of the machine at 0, while the grains dropped through the meshes'iall on the sieve M, made shorter than L to deliver through P to the space Q below, or, when the valve N is turned into the position represented in dotted lines, the grain will also be delivered outside the case, and mix with that from the sieve L.

R R are bolts passing through the sides of the case, and secured by screw-nuts on their inner ends.

8 s are notched metal plates, screwed to the under side of the sieve M, and forming the bearing-surfiices of said sieve on bolts It. Thus the sieve will be shaken vertically as it is reciprocated.

Having thus described our invention,

We claim as new and desire-to secure by Letters Patent- 1. The rod G, slide 0, and bar D, in combination with the shoe, so as to be simultaneously operated, as set forth.

2. The arrangement of the notched plates 5 on the sieve M, and the screw-bolts R, adjustable in slots in the case, as set forth and shown.

3. The arrangement of the valve N in connection with the long sieve L and short sieve M, so as to deliver hoth the coarse and fine grain outside the case, or one or ,hoth of them beneath the mill, as shown and described.

J. L. RUNK.
