To 4LIIWHOM 1T MAY`` coNcERN lBe it known that I, ELIJAH LINDSLEY, of Neenah, in the county of Winnebago, and in the State of Wiscousin, have invented certain new and useful Improvements in Grain-Fans; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,

and to the letters ofA reference marked thereon. v

I The nature of my invention consists- First, in bending the sieves and raising the rear ends thereof, by which arrangement the grain can be cleaned much better and much faster thanl with the straight or common sieve.

Second, in attaching .a fine screen to the shoe which holds the sieves,under the sieves, said screen being shorter than the sieves, and connected at its front end with the screen-board.

Third, in attaching a shorter screen under the screen-board, and providing said bottom screen with a spout, j for the purpose of carrying the grain out at the side of the mill, by which arrangement the grain is at once deposited into bags, without falling to the ground or door, thereby saving one-half ofthe labor in cleaning grain.

.'In order to enable others sklled in the art to make and use my invention, I will'now proceed to"d"escribe' its construction and operation', referring ,to the annexed drawings, which form a partei' this specification, and Y in which- Figure 1 is a perspectiveview of the machine.

Figure 2, a perspective view of the shoe with its attachments.

Figure 3, a rear view of the shoe.

Figure 4, a front viewof the same; and

Figure 5, a cross-section of the shoe, showing the position of sieves; screens, Ste.

yA represents a frame, made of suitable material and of any size required, the rear end of which is cylinder-X shaped, to allow 'a fan'tc revolve i-n the same.

This fan consists merely in a shaft, which has its bearings in the sides of the frame, and is provided with arms on which s'latsare secured. l'.lhe fan is turned by means of a crank, C,` and gear-wheel D, on the side of the frame A. v A In the rear end, and inside of the frame, the shoe a is hung, by means'of hooks h h at each side thereof. This shoe consists of side-pieces, shaped as shown in iig. 5, with a cross-piece at'thelower end,connecting the same.

VBetween' the sides of this shoe, and secured thereto, are the sieves,'b and c, the rear ends of which are bent upwards, as shown in {ig.v5. These sieves may be constructed of any suitable material, with such apertures as to allow the grain to pass through, but the upper sieve should have larger apertures than the lower, so that .some chaif, Ste., whichpa'sses through the upper will not pass through the lower sieve.

Under the lower sieve, c,`is a. wire screen, li, placed, which is also attached to the sides of the shoe a, in such a manner that it inclines slightly forward, not extending as far forward as the said sieves, and connected .at its frontend with the screen-board e, which inclines towards the rear of the mill.'

VCockle" or other foreign matter passes through the screen d and falls on the screen-board E, out under .the `mill, whilethe grain `rolls off said screen,ithe apertures therein not being large enough to allowl it to pass through, andfalls o'n to another wire scr'een,f, placed between tho' lower edges o f the shoe a, and is fastened to the cross-piece connecting the sides thereof, the wire board e also being fastened to said cross-piece, and thus forming a funnel or hopper for the grain. i

'.The grain, after falling on this short screen,fpasses out through the spout g,vwhich protrudes through an opening in the side of the frame A. Around this holo or opening is some arrangement for hanging a bag, so that the grain will pass at once into the same, without falling to the ground or oor.

A rod attached to the lower end of the shoe, and .passing v around a cam-wheel on the shaft of the fan in the front part 44of `the machine, jars the shoe, so that the grain will pass through the sieves'without clogging, 'and the said fan' blows all dust, &c., away from the grain.

Having thus fully described my invention, whattl claim as new, and desire to secure by Letters Patent, is-

1. The sieves b and c, when bent as described, and operating as and for the purposes herein set forth.

2. The screen d, in combination with the sieves b and c, when constructed and operating asvand for the purposes herein set forth.

In'testmony that I claim the foregoing, I have hereunto set my hemd, this 11th day of May, 1868.

ELIJAH LINDSLEY.
