IMPRovnMENT IN FANNING-Mmns.

The Schedule referred to in these Letters Patent and making part of the am@ To all whom it may concern:

Be it known that I, HARVEY F. SEIBERT, of Bradys Bend, in the county of Armstrong, and State of Pennsylvania, have invented a new and useful Improvement in AI4anning-l1Iills and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, formi-ng part of this specification, in which- Figure 1 is a vertical longitudinal section of my improved fanning-mill, taken through the line x a1, iig. 2.

Figure 2 is a top or plan view of the same, part being broken away to show'the construction.

ftFigure 3 is a detail cross-section of the revolving si er.

Figure 4 is a detail cross-section of a modification of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the coneifective and reliable in operation; and

It consists in the revolving sifters, in combination with the other parts of the mill, as hereinafter more fully described.

A is the frame, and B is the case of the fanningmill.

C is the shaft to which the fans D are attached, and to which motion is given by a crank, E, and gear- Wheels F, in the ordinary manner.

The fans D are slightly concaved, as shown in fig. 2, to cause them to drive the blast of air more directly upon the grain as it enters the mill.

G is the hopper from which the grain enters the mill, and the lower end or spout of which is'so formed as to conduct the grain into the upper end of the revolving sifter.

H is a shaft, the inner end of which revolves in a socket in the bar I,. the ends of which are securely attached to the case, or frame of the mill.

The outer end of the shaft H enters a slot, or groove in the standard J, where it is supported at any elevation, according to the inclination which it is desired the said shaft H should have, by a pin passing through one or the other of the holes formed for its reception in the said standard J.

`The lower end` of the standard J is attached to the rock-shaft K, the ends of which are pivoted to the casing B of the mill.

The upper end of the standard J is secured in place by apin passing through a hole in the upper part of the case B, and into a hole in the upper endv of the said standard J.

By this construction, the upper end of the standard J may he detached and swung outward, to allow .the shaft Htc be detached.

L is a cylindrical case attached to the outer ends of the arms N, the ends of which are rigidly attached to the shaft H, so that .the said cylinder L may be carried around with the shaft H in its revolution.

0 is a cylindrical screen placed within and secured vto the cylinder L, so as to be carried around. the said cylinder in its revolution.

'lhe screen O is made a inder L, so as to leave a space between the said screen and cylinder, for the small seeds to drop into, and pass out at the lower end of the cylinder L.

P are longitudinal flanges, attached to the screen O, or to the cylinder L when the screen O is not used, which said flanges, as the shaft H is revolved, lift the grain, and allow it to fall back, so as to keep the grain all the time stirred up. f

For cleaning rye, oats, buckwheat, corn, and similar seeds, the flanged cylinder L is used without the screen O, but for cleaning wheat, clover-seed, timothy-seed, dax-seed, Ste., the danged cylinder L should be used with the screen 0. p

Q is a partition, which separates the fan-chamber from the other parts of the mill, and which is made with a hole through its middle part, in which hole is placed a short cylinder, or tube, R, by which the grain is conducted in-to the fan-chamber, where it falls through the rack, or screen S, to the inclined board 'l, by which it is conducted out of the mill.

rlhe screen O should b'e made a little longer than the cylinder L, so as to conduct the grain into the tube R, while allowing the small seeds, separated by the said screen O, to drop down outside of the partition Q.

The chai` is separated from the grain during its passagethrough the cylinder L, and any straws, sticks, and other coarse substances, that may bein the grain, are separated by the rack, or screen S, down which they slide, and thusv pass out of the mill.

.U is a pulley, attached to the inner part of the shaft H, and around which the band V passes.

The band V also passes around the pulley W, attached to the shaft X, which revolves in bearings, in supports attached to the case, or frame of the mill, .and to the end of which is attached a bevel-gear wheel, Y, the teeth of which mesh into the teeth of the bevel-gear wheel Z, attached to the end of the fan-shaft G, so that the cylinder L may be operated from the said fan-shaft.

Having thus described my invention,

I claim as new, and desire to secure Patentl. The combination of the slotted and pivoted upright, J, rock-shaft K, adjustable shaft H, short cylinder L, long vinterior screen O, tube R, partition Q, and inner bearing I, all arranged as described, for` the purpose specified.

by Letters 2. The combination of thev standard J, and rocky shaft K, with the shaft H, and case, or frame of theV mill, substantially as herein shown and described, and for the purpose set forth. v

3. The arrangement of the pulleys U W, band V, shaft X, and bevelled-gear wheels Y Z, with relation to the cylinder-shaft H and fan-shaft C, as herein described, for the purpose specified.

XVitnesse's: HARVEY F. SEIBERT.
