UNITED STATES PATENT OFFICE.
CHARLES H. BLANCHARD, OF BATAVIA, OHIO.
AUTOMATIC FAN.
SPECIFICATION forming part of Letters Patent No. 271,211, dated January 30, 1883.
Application filed October 13, 1882. (No model.)
To all whom fit may concern:
Be it known that I, CHARLES I -I. BLANCH- ARD, of Batavia, Ohio, have made a new and useful Improvement in Automatic Fans, ot' which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specication, in which- Figure l is a view in perspective of the improvement in position 5 and Figs. 2 and 3, details, being sectional views taken through the casin g. Fig. 2 shows the arrangement when a cord and weight are used, and Fig. 3 when a spring is used.
The same letters denote the same parts.
The present invention is an improvement in fans used to agitate the air in sleeping-apartments, sitting and dining rooms, workshops, and other places, and for driving away iies, mosquitoes, &c.
It consists of a revolving fan actuated by a cord and weight, the fan being connected with a casing or frame containing gearing for operating the fan, and the fan and casing being suspended by a vertically-adjustable connection from an overhead support.
A,Fig. l, represents the fan, having one or more vanes, ce a'. It is attached to a shaft, B, which in turn is supported in or upheld by a casing or frame, G. This casing or frame is suspended from an overhead fixture-say, the ceiling D.
The suspending device E is constructed so as to make the fan vertically adjustable; and to this end the suspensory E may be in two parts, c and c', the lower part, c, being movable upward an d downward upon the upper part,
e', and xed at any point thereon by means of the set-screw c2.
A weight, F, is suspended from a cord, Gr, which passes over bearings H H, and thence around a drum, I, upon the shaft J. This lastnamed shaft rotates in bearings in the casing O, and a train of wheels, K L, communicates the motion of the shaft VJ to the fan-shaft B.
In operation, the weight F, by applying a key to the shaft J at j, iswound up toward the Y the shaft B,the casing C, the vertically-adjustable suspensory E, the weight F, the cord G, the drum I, the shaft J, and the train L K, substantially as described.
2. The combination ot' the revolving fauA, the casing O, the shaft B, and the rods c e', the rod e being vertically adjustable upon the rod c', substantially as described.
3. A revolving fan, A, actuated by a train of gearing, said fan and train having a vertically-adjustable connection with an overhead fixture, D.
4. The revolving fan A, having the removable fringes M, as and for the purpose described.
