UNITED STATES ABRAM FANOKBONER, OF SCHOOLCRAFT, MICHIGAN.

IMPROVEMENT IN GRAIN-SEPARATORS.

Specication forming part of Letters Patent No. 31,!14, dated January 15, 1861.

To all whom t may concern: y

Be it known that I, ABRAM FANCKBONER, of Schoolcraft, in the county of Kalamazoo and State ot Michigan, have invented a certain Improvement in Fan-Mills, the construction and operation of which I have described in the following specification and illustrated in its accompanying drawings with sufficient clearness to enable competent and skillful workmen in the arts to which it pertains or is most nearly allied to make and use my invention.

My invention consists in thel arrangement and combination ot' a hopper, screens, and receptacles, as hereinafter described, for the purpose of separating tine seeds from the coarse and the different grades of tine seeds from each other immediately after their entrance into the mill, after which the large grains are cleaned by the action of the fan during their passage over and through the larger screens, which are placed lower down in the mill, as I have more fully set forth in the following` description and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a side elevation of a tan-mill. Fig. 2 is a vertical Iongitudinal section made by a plane passing through the center of the machine. Fig. 3 is a vertical transverse section showing the parts to the right-hand side of the line a; a: in Fig. 2. Fig. 4 is a vertical transverse section showing the parts to the right-hand side of the line y y, Fig. 2.

1 is the hopper at the top of the' mill, into which the grain to be cleaned and separated is poured, its opening in the lower side being partly over and partly to the left of the first screen on which the grain falls. This screen, which is represented at 2 in the drawings, is made ot' wire, and the meshes are just far enough apart to allow all but the plump perfeet grains to pass through. To the left of this screen will be seen in the drawings a board 16, which extends the full width of the screen and slopes or inclines a little to the right, as does also the screen. Under the said board and fastened to it is another board 15, which is concave on the upper side and inclines in the same direction as the said board 16 and screen 2 and in a greater degree.

3 is a second screen made similar to the drawer t) is made ot a lengthv equal to the width of the machine, and of a width sufficiently great so that the grain in falling from the pipe 8 will not be thrown over the edges and outside of the drawer 9 by the vibratory motion of the parts to which the pipe 8 is attached.

4 is a receptacle or box under the screen 3,

which is connected by means ot the tube 5 to the box 6 on the outside of the case. There is an elongated opening in the side of the case between the case and the receptacle 6, in which the end of the tube 5 plays. By the vibration of the receptacle 4, to which the tube 5 is attached, the ygrain is shaken out through the tube or spout 5 into the box 6.

1l is a screen made with meshes still larger than those of the two other screens and inclining in the opposite direction.

12 is a screen exactly similar to screen 11, with the exception that it is inclined still more and in the same direction.

The screens 2, 3, 4, 11, and 12, the receptacles 4 and 7, and the guide-boards 15 and 16 are hung in a vibrating or shaking frame, which is operated by a crank from the shaft on which the fan is hung.

13 is a board convex on the upper side, (although a straight board will answer the purpose,) and so placed that its right-hand edge, as seen in the drawings, is somewhat under the lett-handl edge of screen 12.

14 is an opening to and through which the board 13 guides or carries the grain.

The mode of operation of my fan-mill is as follows: The grain to be cleaned being placed or poured into the hopper 1, it passes through the openingin the bottom of said hopper and falls upon the board and screen 2. The part the grains of which are small enough to pass through the screen 2 falls partly on the screen 3 and part-ly on the board 15, and thence to the screen 3. The screen 3 separates all the smaller seeds which fail upon it fromy the larger kinds, the smaller ones failing through the screen 3 and into the box 4, whence they are conveyed by means of the spout 5 to the box 6, whence they may be removed at pleasure. Those grains or seeds which are too large to pass through the screen V3 pass over it and into the receptacle 7. Thence by means of pipe 8 theyr slide into the drawer 9. The large plump grains which would not pass through the screen 2 pass over it and fail on the screen 11, where they are first exposed to the action ot' the blast from the fan. From the screen 11 they fail on the screen 12, thence to the board 13, and out at the opening 14.

From the time they fall on the screen 1l tili they arrive at the opening 14 they are oontinuaiiy subjected to the action of the fan.

Having` thus fully described and illustrated my invention, I claim- The arrangement of the screen 2, screen 3, receptacle 4, receptacle 7, spout 5, pipe 8, box G, and drawer 9, in combination with the vibrating frame containing the screens of a common fan-mili, as herein set forth and described.

ABRAM FANCKBONER.
