THOMAS M. BALES, OF DUBLIN, INDIANA.

FANNlNG- MlLL SPECIFICATION forming part of Letters Patent No. 453,532, dated June 2, 1891.

Application filed January 3, 1891.

To aZZ whom it may concern..-

Be it known that I, THOMAS H. BALES, a citizen of the United States, and a resident of Dublin, in the county of \Vayne and State of Indiana, have invented certain new and useful Improvements in Fauning-Mills; and I do 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 drawin gs, and to letters of reference marked thereon, which form a part of this specification.

Figure]. of the drawings is a representation of the invention and is a perspective view. Fig. 2 is a side elevation. Fig. 3 is a vertical section, and Fig. 4 is a detail view.

The invention relates to certain new and useful improvements in grain-cleaners; and it consistsin the novel construction and combination hereinafter set forth.

The object. of the invention is to providea device of the character named which Wlll have a maximum working capacity in proportion to its size, and, further, to so arrange the blowing mechanism and discharge as to prevent to a large extent the filling of the surrounding atmosphere with dust and chaif when in operation.

In the accompanying drawings, illustrating the invention, the letter A designates the supporting and inclosing frame, and B the hopper secured thereto. 0 is a gear-wheel ournaled in one side of the frame and provided with an operating-crank C.

D represents a fan-wheel driven by a pinion a, meshing with wheel 0 and inclosed 1n the casing D. This Wheel consists of the oppositely-curved fans or wings d and d.

E E are vertical bars or levers, one on each side and provided near their upper ends with vertical slots 6 6', adapted to receive and engage, respectively, projecting eccentriclugs b b, one on the outer surface of the pinion a and the other on the opposite end of the fan-wheel shaft.

F F represent, respectively, the upper and lower shoes or shakes suitably supported in the frame and inclined from opposite ends and so arranged that the lowerend of the upper shoe is directly over and but a short distance from the upper end of the lower shoe.

Serial No. 376,671. (No model.)

These shoes are connected, respectively, to the lower end portions of the bars E E by means of suitable clips or irons f and pivot-pins therethrough and receive a vibratory reciprocating motion therefrom. The upper shoe F is provided with one or more interchangeable screens G and a solid bottom G, in order that the grain may be carried to and discharged into the upper end of the shoe F. This latter shoe has double screens of diifen ent grades for the purpose of separating the wheat into first and second grades. These screens are removable to provide for the use of different grades or meshes.

h h are small strips pivoted in the lower shoe and which may be turned so as to throw both kinds of the grain to the same or different sides of the spent, so that they may be discharged together or separately, as may be desired. The third grade or screenings will pass through the lower screen and be discharged through the spout h.

H represents the chaff box or chute, having a discharge-opening at 1-1 on the side of the machine opposite the operating-crank. This chute is so arranged as to receive the entire amount of the dust and chaff from the grain as it passes from the hopper to the upper shoe under the action of the blow-fan, which, with its curved wings, will give an upward and downward blast to the chaif, throwing it into the chute and out 011 the side of the machine opposite the operator, and thus prevent his becoming covered with the dust, ((56. By this arrangement, also, but a small fan or blow is necessary, thus requiring less power to run it. The chaff or dust, by being blown out before reaching the middle or screens in the shoes, prevents their clogging up, thus giving the machine a greater capacity, and much less dust and chaff is thrown out into the surrounding air than in machines where the blast is forced up through the screens.

K K are rods or bars pivoted at one endto the uprights 2 of the frame and at their opposite ends to the bars E E, respectively, at a point preferably somewhat nearer the upper shoe than the lower, in order to give alonger stroke or movement of the latter than of the former shoe. This longer stroke is necessary for the lower shoe in order to keep the grain from clogging thereon. A rod L supports each side of the lower end of said shoe and has a pivotal connection therewith, giving a lifting motion thereto when the parts are in operation to still further prevent clogging. These rods are set at such an angle as not to be parallel with the rods E E, as such arrangement would prevent movement of the shoes to any extent. i

It will be seen that the grain and chaff run through this machine may be separated into four grades by one operati0nviz., chaff, first and second grades, and screenings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The grain-cleaner having its upper and lower shoes inclined oppositely to each other, the blast-wheel arranged above said shoes, slotted rods engaging eccentric pins or lugs on the blast-wheel and pivotally connected to the shoes, and pivoted supports for the lower shoe, substantially as specified.

2. The combination, with the oppositelyinclined shoes and the blast-wheel arranged above said shoes, of vertical slotted rods engaging pins or lugs on said blast-wheel shaft and pivotally connected to. said shoes, and horizontal rods pivoted to the frame and to said vertical rods at a point near the upper oi the two shoes, whereby the length of a stroke of the two shoes is varied, and pivoted supports for the lower end of the lower shoe, substantially as specified.

3. The grain-cleaner having its blast-wheel located above the upper shoe and having the oppositely-curved fans or blades to give an upward and downward blast to the chaff as the grain passes from the hopper to the upper shoe, in combination with the chaif-discharge chute, also located to receive the chaif above said shoes, said chute arranged to discharge at the side of the machine opposite to theoperating-crank,substantiallyasspecified.

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

THOMAS M. BALES.
