AUTOMATIC FAN.

SPECIFICATION forming part of Letters Patent N 0. 701,078, dated May 27, 1902.

Application filed July 16, 1901. Serial No. 68,480. (No model.)

To (LZZ whom, it 'ITML/j concern.-

Be it known that 1, Moses OTTENHEIMER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Automatic Fans, of which the following is a speci iication.

This invention relates to automatic fans; and its object is to provide a device of this character which can be readily attached to a bed, chair, or the like and extended in operative position over the occupant of the same and which when not in use can be readily folded into compact form, so as to be stored away or carried from one place to another.

The invention consists in certain constructions, arrangements, and combinations of the parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a top and rear perspective View of my improved automatic fan in extended and operative position. Fig. 2 is a vertical section thereof attached to a bed and with the pivoted fan-supporting arm swung back into folded and inoperative position. Fig. 3 is a side view of the free end of the fan-supporting arm and illustrates in section the bearings of the fan-shaft. Fig. 4 is a sectional view of the standard and its pivoted fan-supporting arm on the line :0 m of Fig. 2. Fig. 5 is a side view, on a smaller scale, of the automatic fan secured to the back of a chair.

Referring to the drawings, the referencenumeral 1 designates a casing for inclosing the power mechanism, which maybe any suitable power, and in the present instance is a spring-motor comprising a spring 3, adapted to be wound up by a handle 24 and communicating rotary motion to a driving-pulley 4 b means of pinions 2 as illustrated in Fi a. y 1 c 2. At its top the casing is provided with forwardly-extending angle brackets or hangers 19, adapted to take over the article to which the fan is to be connected-such, for instance, as a bed 20, asillustrated in Fig. 2, or a chair 21, as illustrated in Fig. 5.

Rising from the top of the casing 1 and rigidly secured thereto is a vertical standard 9, preferably formed of channel-iron, so that it is provided with a longitudinal recess 22, opening rearwardly, as indicated in the drawings.

Said standard is provided at its upper end with two side ears 22, rising above its front wall 22*, so that the upper edge of said wall forms a shoulder 22, for a purpose hereinafter describe hand said standard is also provided at its upperend with forwardly-extending slotted brackets 13, in which are journaled idle rollers 6, tensioned by springs 12. A pivot-pin 11 passes through the said ears 22 and is provided with a thumb-nut 11, and a fan-supporting arm 10 is provided at its rear end with a knuckle, by which it is pivotally mounted between said ears on said pin and is provided with a longitudinal strengthening-web 23, which when the said arm is swung back is received into the recess 22 of the standard, as illustrated in Figs. 2 and 4, and when said arm 10 is swung to the forwardly-extending position (illustrated in Figs. 1 and 5) it abuts against the shoulder 22 of the standard, and is held thereby in operative horizontal position.

Journal-bearings 14 are formed in the free end of the fan-supporting arm 10 and its depending bracket 15, and a fan -shaft 9 is mounted in said bearings and is provided with nuts 17, having races 16 to receive antifriction-balls 1b to facilitate the rotation of said shaft. Fan-blades 8 are secured to said shaft 9, and also secured to said shaft is a pulley 7. An endless band 5 passes around the said pulley 7, over the idle rollers 6, and around the driving-pulley 4, whereby to revolve the fan-blades when the supportingarm 10 is swung to the forwardly-extending position. (Illustrated in Figs. 1 and 5.)

In practice the automatic fan is secured in place by means of the hangers 19, with its fansupporting arm 10 swung to the forwardly-extending horizontal position. The fan can then be operated by winding up the springmotor. WVhen it is desired to store the fan away, the said arm 10 is swung back, with its web 23 received in to the recess 22 of the standard, and the fan is then in compact folded condition.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An automatic fan, comprising power mechanism, including a driving-pulley; a casing for said mechanism; a standard ris ICO ing from said casing and provided at its upper end with forwardly-extending brackets; spring-tensioned idle rollers journaled in said brackets; afan-su pporting arm pivotally connected at one end to the upper end of said standard above said brackets and idle rollers; a fan-shaft mounted in the free end of said arm and provided with fan-blades and a pulley; and an endless band passing around said shaft-pulley, over said tensioned idle rollers, and around said driving-pulley, as set forth.

2. An automatic fan, comprising power mechanism, including a driving pulley; a casing for said mechanism; a standard rising from said casing and provided with a longitudinal rearwardly-opening recess, and also provided at its upper end with forwardly-extending brackets and a shoulder, 22, and side ears, 22, above said brackets; a fan-supporting'arm pivotally mounted at one end be- MOSES OTTENHEIMER.
