FLY-FAN.

SPECIFICATION forming part of Letters Patent No. 57 6,083, dated February 2, 1897.

Application filed August 19, 1895. Serial No. 559,812. (No model.)

To a-ZZ whom it may concern.-

Be it known that I, WIL IAM P. ANDREWS, a citizen of the United States, residing at Brierfield, in the county of Bedford and State of Virginia, have invented a new and useful Fly-Fan, of which the following is a specification.

Hy invention relates to fly-fans adapted for use in connectionwith tables and designed to be mounted upon a chair for operation by means of a treadle arranged within reach of the foot of a person occupying the chair; and

the object in view is to provide a device of the class named which may be readily mounted upon and dismounted from a chair without the manipulation of set-screws, clamps, and the like, and which when removed leaves the chair in practically its original condition, whereby it is adapted to perform its usual functions.

It is a further object of my invention to provide such means in connection with a chair for supporting the fan mechanism as to be readily attached to a chair of the ordinary construction without special preparation thereof.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure l is a perspective View of a fan mechanism embodying my invention mounted upon a chair in its operative position. Fig. 2 is a detail view in perspective of the oscillating socket and crankarm, which is mounted upon the chair to support the fan-shaft, said member being shown detached. Fig. 3 is a similar view of the bracket, which is adapted to be attached to a chair and is provided with a bearing for the oscillating socket.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlugs.

5 designates a bracket adapted to be attached to a chair-seat 6 by means of screws or other suitable fastening devices, and comprising a horizontal plate' having its inner portion recessed to form a shoulder 5 to abut against the side edge'of the seat and a vertical socket 7 formed integral with the outer The fan-shaft is adapted to carry a fan 14 of any suitable construction.

- The oscillating socket is mounted for rotary movement upon a vertical axis in the bearing at the extremity of the bracket 5, but is removably seated therein to provide for easy removal when the fan mechanism is notrequired, thus leaving the bracket 5 alone attached to the chair, and inasmuch as this bracket projects but slightly beyond the side edge of the chair-seat it will be understood that it will not interfere with the usual function of the chair, and, furthermore, that said bracket may be readily applied to any chair of the ordinary construction to adapt it to receive the improved fan mechanism.

Various means may be employed for communicating motion to the oscillating socket to oscillatethe fan, said oscillating socket being preferably provided with a depending crankarm 9, to which motion is communicated from the operating mechanism by means of a pitman 13 or its equivalent, said crank-arm be in g dropped or arranged in a pendent position in order to apply the motion at a point below the socket 7 and thus out of the way of the clothing of the occupant of the chair. The arm 9 is substantially S-shaped, and it extends outward and downward from the oscillating socket, and the pitman which inclines downward from the lower end of the arm is located at a point below the bracket, so that the strain incident to the operation of the fan serves to retain the journal in the socket 7 The operating means illustrated in the drawings include a treadle 1, provided with lateral trunnions 2, which are mounted in open bearingsin the upper sides of fixed bearing-blocks, said treadle being provided with an upright arm 3, to which the front end of the pitman 13 is pivotally connected, and it is obvious that the foot of a person occupying the chair may be comfortably arranged upon the treadle to provide for communicating the desired motion thereto.

The special point of advantage connected with the mechanism above described consists in the facility with which it maybe mounted and dismounted, the only operation necessary to dismount the same being the lifting of the rock-shaft vertically from the bearing in the bracket and at the same time raising the trunnions of the treadle from the open bearings in the block 4. Thus a single operation accomplishes either mounting or dismounting of the device, while in operation accidental displacement is prevented, in so far as it re lates to the rock-shaft, by the depending or side edge of the seat, said plate extending outward beyond the seat, and a vertical hearingsocket 7 formed integral with the outer end of said plate and arranged on the upper face thereof, an oscillating socket provided with an integral depending journal 8 arranged in vertical alineinent with the oscillating socket and removably stepped in the socket '7 of the bracket, the depending S-shaped arm 9 formed integral with the oscillating socket and extending downward and outward from the same to a point below the said bracket, a fan-staff secured within the oscilatin g socket, and a pitman connected with the lower end of the depending arm at a point below the bracket and designed to be operated by a treadle, said pitman inclining downward from the said arm, whereby the strain incident to the operation of the fan will serve to retain the journal 8 in the socket 7.

In testimony that I-claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

VILLIAM P. ANDRElVS.
