Letters Patent No. 90,936, dated June 8, 1869.

IMPROVEMENT 1N PANNING-MILLS.

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

To all whom it may concern Be it known that I, EDWIN P. DICKE r, of the city and county of Racine, and State of Wisconsin, have invented a new and useful Improvement in Fanning- Mills; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying draw- The nature of my invention is to produce a fanning.

mill which will clean grain in a superior manner, and bag it for market.

A is the frame and outside work of my invention.

B is an elevator for raising the grain after it has gone through the mill.

0, pulley which drives the elevator.

D, belt which drives the elevator.

E, balance on the fan-wheel shaft, to which the fan-wings are fastened.

F, trucks under the forward standards of the machine, with which the machine can be run round over the floor; These trucks are made with their outer edges larger than their inner edges, so that they shall take hold of the floor and not slip. p

G, a stop in the elevator, which is hung by a chain, and when in place, turns the grain into the-hopper as it is raised, and when out of place, lets the grain fall to be bagged.

H, driving-wheel.

I, crank with which the-mill is operated.

K, a wheel fastened to the cog-wheel on the fanwheel shaft, with pins outside of the centre, so that the shaker-pitman may enter it, near the centre, to give the shaker a shorter stroke than itcould have if it had a shaft in the centre.

L, shaker-pitman.

M, shaker-lever. v N, spout from which the best grade of wheat shall fall. This spout is hung to the shoe, and shakes with it.

0, box to catch the fine seeds that shall fall through the sieves. g

P, 'cuwed fanning-wings. These wings are made curving, so as to throw the wind evenly over all parts of the sieves.

Q, pinion on the fanning-wheel-shaft.

R, elevator-chain and buckets.

S S, pulleys over which the elevator-chainandbuckets are made to revolve.

T, eccentric which holds the feed-board of the hopper in place.

U, feed-board to the hopper, made slanting on the inner edge, so that a sharp or feather-edge comes down on to the shoe to prevent the wheat from clogging.

V, end-board setting in grooves made of metal, with notchesin the said grooves, with which pins in the endboard fit into and hold the board in place.

\V, piecesof metal on the end of the shoe, through which a rod passes, with a nut on one end of it to hug the end of the shoe together, and hold the hurdle firmly in place.

X, strips of metal with which the shoe is'hung, with wedges between the shoe and these strips of metal.

Y, a wooden or tin cover which covers the lower sieve,

.to prevent fine seeds from falling through when cleaning fine seeds. I

Z, awooden, or'tin cover over the sieve, to prevent small seeds from falling through when it is desired to keep them up.

a, outlet on the side of the elevator, for the grain to pass out of when not desired to throw it into the hopper again, and hooks to hang on bags and bag the gram.

7), outlet for the grain to the elevator. The grain may be so divided as to have thebest fall out through the outlet N, and the second grade through this opening,

or all of it may be let-out through this outlet and bagged.

c c c, stiles to the sieve in the hurdle, graduated as to wideness, so that when oats fall through the meshes in the sieve, they shall fall on to the stile below and be brought round sideways again,

d, handles to the machine, to move it with. One can take hold of these handles, and raise up that end of the machine, and run it on the trucks to any place desired.

e, sieve, with meshes arranged three and one-half by three and one-half to the inch, for cleaning oats from barley.

f, adjustable rod, which tightens up the end of the shoe, and holds the sieves in their place.

g, pins on tail-board V, with which to adjust it.

h, grooves for the tail-board V. I

t, adjustable grader, which, when hauled back, so as to make an opening in front of it, allthe grain, or the No. 2, will run back out of the machine.

7:, board to convey wheat or other matter to the back side of the mill.

1, wind-board.

m, hurdle made and fastened together in one piece.

Operation.

Adjust the mill according to the work you want to do. Turn the crank, which will turn the fan-blower, and the other Works being connected, put your Wheat in the hopper, and as it is fed through, it passes down through the mill. The first quality passes out of opening'N. The second grade passes out through spout b, and is carried up by the elevator, the stop G being in place, and falls into the hopper again. Or if-you wish to send the wheat up through elevator and bag it, remove the stop G, and hang a bag on to the hooks at opening a. Or'if you wish to send all the Wheat out through the back of the machine, pull sieved forward, and the wheat will all fall down and go out the back side of the mill. I

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Adjustable rod f, in combination with metalpieces W, when those metal pieces project out over the shoe,

. and the openings for thegrod fare made open like-hooks,

substantially as and for the purpose described.

2. Tail-board V, in combination with metal grooves h and knobs, g, when made and arranged substantially as described.

' stantially as described.

7. Hanging spout b on to the shoe, substantially as described.

8. A hurdle, when made as shown by fig. 6, with meshes in squares, three and one-half in number, to i the inch, each way, in combination with the stiles at the head of the hurdle of different widths, the upper stile the narrowest, and the next a little wider, and so on, for the purpose of cleaning oats from barley, substantially as described.
