' IHVIPZRO'VEI) GRAIN-FAN.-

The Schedule referred to inthese Letters Patent and part of theieame To an whom may concern:

Be it known that I, JAMES MoPrrAIn, of Charles 1 Gity,in the county of Floyd, and in the State of Iowa, have invented certainnew and useful Improvements in Grain-Fan; and do hereby declare that the following is a full, clear, andexac't description thereof, reff erenc'e being had to the accompanying drawings and part of this specification. I V

The nature of my invention consists in the arrange naent and construction of a grain-fan, in providing the any desired angle, as will Figure 1 is a perspective of my invention.

Figure 2 is a similar view of the bag-holder detached from the frame. 1 4

- Figure 3 is a section view of my grain-fan.

Letter A represents the frame,whioh is constructed of any desired shape or size, and which has the fan B placed in its front end. a

Extending upward from each side of the frame is a standard, 0, which supports the revolving buckets D immediately above the hopper, so that as the grain falls from the spout it fills the buckets, andthns causes them to revolve, thereby generating the power which is to revolve the fan.

4 Attached toone end of'the'shaft E which passes throughthe overshot-wheel D, and which has its hearings upon the standard 0, is'a pulley, F, around which passes the belt G, and thus communiL-atesthe Secured to the shoe H there are two screens,,one-

ofwhich is stationary, while the second one is loose, and can be adjusted at pleasure. l

The stationary screen llis smaller than the adj ustable one K, which is pivoted to the shoe by a'pivot, L, ateach corner, so that it can be lowered or raised in such a manner as to decrease the number of'screens "usually required ingradingthe grain.

When the screen K is; lowered, so as tohe'on a" level with the smaller one, the whole quantity of grain will flow out at the front end under the fan.

' When raised only partly, then but a portion flows to the front, while that on the stationary screen flows into the 'trough'M, placed justundcr its lower end,

"and passes out the side, and when raised to its full height, the larger portion flows to the front, and only a small portioninto the trough.

In one or each side'of the shoe their 'is a'circular slot, a, cut-,through which a small screw-rod, 1), projects from the side of the soreen'-K,'and is provided with a nut-,'c, so that the screen=can beadjusted and held at any desired point.

to the lettersof reference marked thereon making a' i Q pared for. it.. screens with pivots .so that they may. be adjusted at hereafter be more fully set I sift the grain.

v the wings at any desired point-1- Securd to the rear end of the shoe is a trough,'1 l,

which is intended to catch all the grain which may be driven over the end of the screen.

\ The'r'nouth. of this trough is lower than the opposite end, and has. a number, of perforations made through it, and is provided on its under side with a movable slide, d, so that the openings may be partly or entirely closed.

All the larger and coarser dirt, together with the, straw, will flow over pastthese openings, whilethe grainwill drop through them into a receptacle prevIf desired, there may be .one or more' additional spouts placed under the one N, so as to still farther Hinged to the top of the trough there is an, adjustable cover, 0, which may be secured at any desired point by means of the rod i, so as to prevent the chaff from being driven into the trough, thus making the grain fstill easier to-clean;

1 Passing through a loop, 0, attached to the side of the frame, atthe front end, and througha hole in the post I, is a wooden bar or .rod, P, to which thebagholder is attached.

In the rearside of the bar there is a dovetail groove out, so thatth'e upright standard R, to which the two wi'ngsof the bag-holder are fastened, can be raised or lowered-to any desired-height, or canbe entirelyremoved.

To the top of the standard B there are secured two wings, S', whi'ch form the holder, one of them being stationary,'while the other is loosely pivoted, and has a lever, '1, attached to it, so that it'canbemoved' back and forthvin order to bring the ends of the wings 1 nearer orfarther apart, so 'as to accommodate the mouthsof different-sized bags. These wings may be oonstructedof sheet-iron, and have metal braces passed aroundtheir sides, so as to strengthen them, upon which sharp points are formed, so that the bags can be more securely held.

Upon the top ofthe standard R there is placed the serrated plate V, which catches the lever, and holds If it is. desired, the whole bottom of regular sieve. 3 V

Having-thus described my invention,- What 1 claim, and desire to secure by Letters Patent, is'- 1.;The perforated trough N, attached-to the rear end of the shoe, and provided with the slide 11, substantially'in the manner and for vthe purpose set forth.

' 2 The adjustable cover 0, provided. with the rod i, for securing ,it at any desired point, in combination with the trough N, substantially as specified.

" 3.;lhe adjustable screen K, provided with the-pivthe trough N may be perforated from end to end, so as to form a ots L, so that the flow of the grain may be changed l 6. The standards 0, shaft E, revolving buckets D, from the front end to the side, substantially as specil and pulley F, when arranged to operate substantially in the manner and for the purpose specified.

In testimony that I claim the foregoing, I have here- 4. In combination with the screen K, provided with pivots L, the screen I and trough M, substantially as unto set my hand this 8th day oiNovemher, 1869, set forth. J AMES MOPHAIL.

5. In combination with the screen K and pivots L, the circular slot a, screw-rod I), and nut or thumb- Witnesses: screw 0, when so arranged as to support the screen at GEO. F. BoULToN any desired point, substantially as described. A. H. MCKALLOR,
