EDWARD S. CLARK, OF BUFFALO, NEW YORK.
IMPROVEMENT IN GRAlN-SEPARATORS.
Specification forming part of Letters Patent No. 155,289, dated September 2-2, 187 application filed July 29, 1874.
To all whom it may concern:
Be it known that I, EDWARD S. CLARK, of Buffalo, in the county of Erie and in the State of New York, have invented certain new and useful Improvements in Fanning-Mills; and do hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention relates to fanning-mills or similar machines for cleaning grain; and it consists in the construction of the wings of the fan so that they can be extended and contracted at will. It also consists in a fine wire-screen arranged above the ordinary screens in the shoe of the mill, to prevent the grain from bounding over the sides, all as hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure l is a perspective view of a fanningmill embodying my invention, and Fig. 2 is a longitudinal vertical section of the same.
A represents the frame of the fanning-mill, B the shoe, and O O the lower screens therein, all constructed in any of the known and usual ways. a is the fan-shaft, upon which are secured the arms E E for attaching the 'wings. .These wings are made in two sections, D and D, one section, D, being permanently attached to the arms E, while the other section, D, of each wing is made movable on the stationary part. The movable section 1) is provided with transverse slots 12 I), through which set-screws (Z d are passed into the stationary section, whereby said movable section may be moved out and in as required, and held at any desired point.
The object of this part of my invention is to produce more blast of air a ith less or same amount of shake, and less amount of air with more shake, as may be necessary on the different kinds of grain to be cleaned. This is accomplished by simply increasing or decreasing the size of the fan-wings, as described.
In order to get at the fan to increase or diminish the size of its wings, the head or drum of the mill is made in two sections, G and G. The section G is made fast to the frame A, and the section G is made to fit snugly in the stationary section, and held by buttons h It, so that it can be easily removed to get at the fans to adjust them.
In mills of this kind it often happens, in using considerable shake, that the grain bounds on the screen. To prevent this I place over the screens 0 O, a sufficient distance above them, a fine wire-screen, J, attached to the sides of the shoe, as shown in Fig. 2, so as to keep the grain from bounding over the sides of the shoe.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The wings of a fan for fanning-mills made in sections D and D, the section D of each wing being stationary on the arms, and the section 1) adjustable thereon, substantially as and for the purposes herein set forth.
2. In a fanning-mill, the stationary curved guard-screen J placed in front of the fan above the lower set and in rear of the upper set of the movable screens in the shoe, as and for I the purposes set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 14th day 0 March, 1874.
EDWARD S. CLARK.
