SPECIFICATION forming part of Letters Patent N0. 349,235, dated September 14, 1886.

Application filed November 19, 1885. Serial No. 183,323. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD F. REYNOLDS, a citizen of the United States of America, residing at Bruce, in the county of Brookings and Territory of Dakota, have invented certain new and useful Improvements in Fanning-Mills 3 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. My invention relates to fanning-mills; and it consists in certain novel constructions and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a longitudinal vertical section of a fanning-mill embodying my invention. Fig. 2 represents detail per,

spective views of the vibrating sieve and the vertical separator detached from each other and from the fanning-mill. Fig. 3 is a transverse sectional view of the vertical separator, and Fig. 4 is a detail view of one of the angle-arms for vibrating the sieve from the shaft of the rotary fan.

A represents a fanning-mill of ordinary construction, which is provided at its top with a hopper, a, into whichv the grain to be cleaned is fed, said hopper having an opening which is located above the front end of the vibrating separator B.

0 represents the fan, which is located within a suitable casing, and the shaft upon which said fan is mounted is rectangular in cross-section. Upon these rectangular portions of the shaft the front end of the pivoted bent arm D rests, so that when said shaft is rotated the front end of this bent arm will oscillate.

I) I) represent supporting-straps, which are pivotally attached to the sides of the fanningmill at their upper ends, and their lower ends are pivotally connected to the sides of the separator B, and at the lower forward ends of the separator is located at each side an out wardly-projecting pin, 1), with which the bifurcated end of one of the bent arms 1) engages, so that when the fan is rotated the separator B will be vibrated. The separator B is provided in its upper portion with one or more sieves, 0, upon which the uncleaned grain is fed from the hopper. The blast from the fan will blow the chaff away from the grain and out of the opening at the rear upper portion of the mill. The bottom of the separator B inclines forwardly, as shown, and is provided at its lower end with downwardly-projecting pins d, which engage with perforations in the upper end walls of the vertical separator E. The vertical separator E is made up of two sections, E and E, which are detachably connected to each other, and the upper ends of the rear vertical side pieces are provided with pen forations d, into which the pins d, attached to the separator B, enter, and the lower ends of the end pieces are rounded, as shown at f, and rest upon longitudinal bars f, attached to the frame. The frame of the vertical separator E is held in position at its lower end upon the horizontal bars f by means of hooks g, which are attached to the frame and enter eyes in the lower rear corners of the separator-casing, so that the vertical separator can have a rocking motion upon its supporting-bars f. Each of the end pieces, E E and E E, have rigidly secured thereto a series of inclined boards, F, and these boards are provided with inclined sieves F, which form a central serpentine passage in connection with said boards. These boards are so located between the vertical side walls as to'leave a passage between said walls and the ends of the boards. The board h ex tends outwardly beyond the front side of the vertical separator and projects over the rear end of a drawer or tray, H, and the lower end of the vertical separator is provided with boards 2' and '5, the board i being located at about the center of the separator, while the rear board, i, extends from its bottom to the end of the lower inclined board, as shown, and beneath the same is located an inclined board, 70, onto which the cockle or other foreign seeds fall. It will be noticed that the vertical separator is provided with three serpentine passage-ways, J, J, and J.

' The operation of my machine is as follows: The grain to be separated is placed in the hopper and the fan rotated in the usual manner. The grain and chaff are fed upon the sieve c, and by vibrating the shoe and causing the blast to'pass through from the under side of said sieve the chaff and lighter impurities are separated from the grain. The partiallycleaned grain then falls upon the bottom board of the separator, and is fed into the center passage-way, J, of the vertical separator, and in its downward course comes in contact with the inclined sieves, which cause the foreign seedssuch as mustard, coekle, and other similar seeds-to be separated from the good grain, the good grain continuing downwardly until it reaches the bottom of the vertical separator, where it is fed upon the board K in a cleaned condition, while the impurities are fed into the receptacle H, and into a reeeptaelewhieh may be placed under the fanning-mill in rear of said board K, and under the opening between said board and the rear wall of the vertical separator. It will be noticed that the horizontal and vertical separators are both vibrated in unison by the pivoted arms, each resting upon the shaft of the fan.

It desirable, the vertical separator herein described may be used imlependently of the separator, and the object in making said vertical sieve in two separable parts is that areess can be readily had, when desired, to the iuterior for cleaning the sieves.

I elaim- 1. The combination, in a fanning-mill. of a fan, the horizontal vibrating separator, and a vertical separator having a serpentine passage-way consisting of inclined boards and in clined sieves, substantially as shown, and for the purpose set forth.

2. The combination, in a fanning-mill, of a supply-hopper, a blast-fan, the horizontal vibrating separator, a vertical separator provided with a series of inclined boards and sieves forming a serpentinepassage-way, and devices for connecting the horizontal and vertical separators, whereby the movement of the former is imparted to the latter, substantially as described.

3. In a ianniug-mill, the combination of the main frame, the fan 0, fan-casing, horizontal separator B, connecting-arms D, and fan-shaft for vibrating the same with the vertical separator pivotally supported on the main frame and means for connecting it at its upper end to the horizontal separator, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD F. REYNOLDS.
