AM PHOTU-LITHOGRAPHIC on me (ossmvsi-macsss) UNITED STATES PATENT OFFICE.
EDWARD DUFFNER, OF VIOKSBURG, MISSISSIPPI.
lMlROVEMENT IN AUTOMATIC FANS.
Specification forming part of Letters Patent No. 138,741, dated May 13, 1873 application filed March 5, 1873.
To all whom it may concern:
Be it known that I, EDWARD DUFFNER, of the city of Vicksburg, county of Warren and State of Mississippi, have invented a new and useful Improvement in Fanning-Machines; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which i Figure I is a front elevation of my fan, and Fig. 2 a side elevation of the same.
Similar letters of reference indicate corresponding parts in the two figures.
This invention relates to fans driven by weights or spring power for use in warm weather over tables, beds, office-chairs, &c.; and the invention consists, first, in the arrangement of said fan upon a shaft rotated by mechanism, more fully hereinafter specified; and second, in the novel and peculiar arrangement of a stopping device by which the fan may be instantly stopped and held by means of a lever and pin.
In the drawing, Aindicates the case of a common clock-power, which may be driven by a spring or weight. It is unnecessary to describe this part of the mechanism, as there is nothing peculiar in it. B, the fans which may be made of sheet metal of any kind or of pasteboard, or any other suitable material; but I prefer sheet brass as most suitable. The
blades of this fan may be straight, or may be in the form of a screw according to the purpose for which it is intended to be used. The
armsO which support these fans are secured in a hub, D, which is attached to the end of a cranked fan-shaft, E. This shaft is secured .to the ceiling by means of a hollow tube, F,
the upper end of which is secured to a plate, G, which may be screwed or otherwise secured to the ceiling. To the crank E by connectingrod H motion is communicated to the fans from the driving-shaft I by pinion J and wheel K that are connected with and driven by the 1. The combination, with fan-shaft E, of a clock-power, A, and wheel K, with pinion J and upright crank-shaft I, as herein shown and for the purpose specified.
2. The pinion J, the upright crank-shaft I, and connecting-rod H, when combined with a fan suspended from the ceiling of a building, as herein shown, and for the purpose described.
EDWVARD DUFFNER.
