HURLBERT H. SEELEY, OF FENWIGK, MIOHIGAN.
FANNlNG-MILL.
SPECIFICATION forming part of Letters Patent No. 231,624, dated August 24, 1880,
Application filed January 9, 1880.
To all whom it may concern Be it known that I, HURLBERT H. SEELEY, of Fenwick, in the county of Montcalm, and in the State of Michigan, have invented certain new and useful Improvements in Fanning- Mills; and I do hereby declare that the followin g is a 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.
My invention relates to fanning-mills; and it consists in certain peculiarities of construction, as will be hereinafter more fully set forth, and pointed out in the claims.
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 drawings, in which the figure is a longitudinal vertical section of a fanningmill embodying my invention.
A represents the frame of the mill. hopper, O the fan-case, D the upper shoe, and E the lower shoe, all constructed in any'of the known and usual ways, and the shoes operated by suitable mechanical means from the fanshaft.
The lower shoe, E, contains two sieves or screens, F F, the lower one of which is made shorter than the upper, and a sliding trapdoor, G, is provided, as shown, said door being held by a spring, H. When this trap-door is open two grades of grain will be made or separated, but when closed the grades are put together.
a is the fan-shaft, to which four armed spiders, J, are secured, and the fans or wings attached to the corresponding arms of said spiders. To each set of arms are attached two fans or wings, II, at different distances from the center, the adjacent edges overlapping each other, but with a space between them, as shown. The fans constructed in this manner give more blast than those ordinarily used.
The object of making the fan-blades in two Bisthe parts is to increase the blast. The center set of fans, I, takes the blast from the center and discharges it on the outside set of fans, I, and the spaces between the two sets of fans allow the air to pass in to hold the air to the outside of the drum. As the fan moves a strong current of air passes through the spaces between the fan-blades;
In the usual way of constructing the fans nearly one-third of the air stays in the drum, while by my invention all. the air is discharged in the drum and on the wind-board K. This windboard cuts .the wind off from the fans each time the fans pass the board, and it has two cut-offs to prevent the wind from backing back on the fans.
In the mouth of the hopper B is an adjustable feeder consisting of a head, L, with a series of teeth, I), the head being pivoted in the sides of the upper shoe, D, and held in position by means ofone or more springs, 01. When the teeth are turned down it acts as a rake, and when turned up as a feeder for grain that has been soft.
Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is
1. In a fanning-mill, the double fans I I, arranged upon the arms J in such manner that an airspace is left between the two parts and the adjacent edges overlap each other, substantially as and for the purposes herein set forth.
2. In a fanning-mill, the combination of the convertible feeder and rake L I), and one or more springs, cl, substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 6th day of September, 1879.
HURLBERT H. SEELEY.
