UNITED STATES ROBERT K. FLOETER, OF OHATHAM, ONTARIO, CANADA.

FANNING-VMI'LL.

SPECIFICATION forming part of Letters Patent No. 429,565, dated June 3, 1890. Application filed July 21, 1888. Serial No. 280,591. (No model.) Patented in Canada March 1, 1888.111. 28,586.

of devices hereinafter described and claimed,

reference being made to the accompanying drawings, in which Figure 1 is a longitudinal sectional view of afanning-mill embodying my invention. Fig. 2 is a side elevation of same. Fig. 3 is an enlarged detail plan view of the connections for shaking the upper shoe. Fig. 4. is an end View of the lower shoe. Fig. 5 is a perspective view of the lower shoe, showing the crank-shaft through which said shoe is operated.

S and S designate shoes suspended at two sides of the machine on spring-hangers H and H, respectively.

0 designates a connecting-rod, which connects the under side of the shoeS with the crank on the crank-shaft A. This connecting-rod O is pivo tally secured to the crank on the crankshaftA, and is hinged v to the shoe S at the other end. Motion is communicated to this shoe S by the chain belt B from the chain-wheel D, rigidly secured on the shaft E, to the chainwheel D, rigidly secured on the crankshaft A, and motion is communicated from the driving chain-wheel D tothe shaft E by a chain belt B, passing over said wheel D and another chain-wheel rigidly secured on t-heshaft E on the opposite side of the machine to that shown in Fig. 2.

On the shaft E the fans F F are rigidly secured, so that as the shaft E is operated the fans F F are also operated to raise a large current of air, which is conducted by the deflecting-board I in the direction shown by arrows 00 a: on the grain above the riddle R before it falls on the latter. The action of this current or blast of air on the grain as it falls from the hopper K is to separate therefrom and blow out at the end of the machine all the chaff, dust, and otherlight impurities. The thistle-heads and other heavier impurities that are too heavy to be blown free from the machine are blown as far as the smut-board J, which conducts them off at the end of the machine. This separates this class of impurities from the grain before it falls on the riddle B, so that the grain is perfectly free to pass through said riddle, which it does, and falls on the screens L and L in the shoe S.

The riddle R and smut-board J are adjustable or movable in the shoe S, but may be rigidly secured therein when required. O is a connecting-rod, which connects one arm on of an elbow-lever M with the chain and crank wheel D, and the end of this connecting-rod O is attached to the wheel D at any required distance from the center, so that as the chain-wheel D is operated the elbowlever M is also operated. The other arm m of this elbow-lever M is pivotally connected to the upper shoe S by a connecting-rod 0 so that as this machine is operated the shoe S is shaken laterally, as well as the riddleR and smut-board J, secured therein, which agitates the grain on the riddle R and assists the grain in passing through said riddle.

at its lower edge in the shoe S below the inner end of the riddle R. The deflecting-board is rearwardly inclined and extends slightly above the upper surface of the riddle, and it is adapted to be adjusted or moved on its pivot in order to deflect the blast of air from the fans F to any required point. As shown in accompanying drawings, it is in the proper position for most kinds of grain to separate the impurities from the grain before they fall on the riddle R; but if it is required to separate oats from Wheat it is preferable to adjust the deflecting-board to the position shown by dotted line in Fig. 1-that is, to a position beneath the inner end of the riddle. This is accomplished by first moving the adjustable or movable riddle R sufficiently to allow the deflecting-board 'I to be adjusted to the desired position.

N designates a cylindrical fan-chamber, in which the fans F F work, the air to which chamber passes through the opening 0, and the quantity is governed to a certain extent The deflecting board or valve I is pivoted.

bya pivotal valve N which covers about one half of the opening 0, as shown in Fig. 2; but in Fig. I this valve is thrown back, leaving the opening perfectly free.

I? is the bottom board of the shoe S, which conducts the screenings into the drawer or receptacle P.

T is a rack, in which the screens L L may be held at any required inclination.

U U are connecting-pins, which form a communication between the screens L L to communicate the vertical vibrations from the screen L to the screen L.

V is a valveadjusted by a crank-screw \V to retain the grain in the hopper K or permit it to flow into the mill in any desired quantity.

X is a roller secured by and revolving perfectly free in bearings X, which are rigidly secured to the frame of the machine, and one of these rollers is secured at each side of the shoe S, as shown in Fig. 4.

X X are serrated plates rigidly secured opposite the rollers X to a board X, which is hinged to the frame of the shoe S, so that as the shoe S is operated lengthwise of the machine by the crank-shaft A and connectingrod C and connections the serrated plate pass ing over the roller X gives the board X a vertical movement, as well as the screens L L, by which the grain is delivered perfectly free, even when the screens are at a very slight incline. This board X being hinged to the shoe S, may be thrown back, as well as the serrated plates X from the rollers X. In this case no vertical Vibration would be imparted to the screens L L.

The operation is as follows: The valve Vis closed while the hopper is being filled with grain. The machine is then put in operation by revolving the chain-wheel D in the direction of arrow. The valve V is then opened, which allows the grain to run into the mill, which is acted upon as herei nbefore described. The large grain is conducted oil? the screen L into the trough Q, and thence to a receptacle placed to receive it. The remainder of the grain is caught by the screen L, over the end of which it falls on the floor or into any suitable receptacle placed at that point to receive it. The wild peas and other screenings pass through the screen L and fall onto and are conducted by the board Pinto the drawer P.

Having thus described my invention, I claim- 1. In a fanning-mill, the combination and arrangement of the adjustable deflectingboard I with the air-chamber N, fans F 1*, upper movable riddle It, smutboard .I, and hopper K, said deflecting-board I being movable to conduct the air-blast either above or below the movable upper riddle and smutboard, substantially as shown and described, and for the purpose specified.

2. In a fanning-mill, the combination and arrangement of the deflecting-board 1 with the air-chamber N, fans F F, upper movable riddle R, smut-board .I, hopper K, having valve V, shoe S, and hangers 11, said deflecting-board I being movable to conduct the air-blast either above or below the upper movable riddle R and smut-board J, substantially as shown and described, and for the purpose specified.

In a fanning-mill, the combination, with the lengthwise-reciprocating shoe S and means for operating the same, of bearings X on the mill-frame, provided with the rollers X, the board X hinged to the shoe and provided with serrated plates X and the screen L, located in the shoe and vibrated verticallyin the latter by the hinged board as the serrated plates of the latter move on the rollers, said board being adapted to swing on its hinge into the shoe to disengage the serrated plates from the rollers, substantially as described.
