' subject of the Czar of Russia, residing at No.

528 East Eleventh-street, New York city, New York, have invented new and useful Improvements in Fans, of which the following is a specification.

My present invention relates to improvements in fans for hand or toilet use and the object of the invention is to provide a simple form of rotary fanwhieh may be easily manipulated to produce a strong breeze, and which may be readily folded into compact space when not in use.

The invention is included in the accompanying drawings, in which,-

Flgure 1 is a side elevation. Fig. 2 is a 'lan view. Fig. 3 is a side elevation of the an after folding, Fig.4 is an end View.

Referring by reference characters to these drawings, the numeral 1 desi nates a block or element in which is rotatabl and slidably mounted a shaft or spindle 2 w ich carries at its outer end the fan blades as shown. To the blockon opposite sides are pivotall connected the arms-3 which are normally fbrced apart by the spring 4 which is preferably formed of Wire having divided coils 4? located on opposite sides of the spindle, the ends of the spring being inserted in openings in the arms.

A spiral spring 5 encircling the spindle has one end connected thereto and its other end connected to the block 1. A. flexible cord 6 is connected to each arm and carried inward and wound around the spindle, and the relative arrangement of spiral spring and cord or cords is such that when the arms are drawn together by the grasp of the hand the spiral spring rotates the s nndle and fan in one direction, while the re axing of the grasp upon the arms allows them to be forced apart by the spring 4 and causes the cords to unwind from the spindle and rotate it in the opposite direction against the tension of the spiral .springl The s indle carries at its outer end a rigidl attac ed frame, preferably in the shape 0 a ring 7, which is connected with the end of the splndle b radial arms 7' and to this ring are pivotall y connected as- )Iurality of blade carrying arms 8. The bla e carrying arms preferably have forked inner ends 8", the pivotal connection being efiected by passing the ring which is round in cross section directly through openipgs in the forked Specification of Letters Patent.

ends, though of course any form of pivotal connection suitable for the purpose maybe adopted. The arms 8 are provided with upwardly turned V-shaped outer ends 8 as.

shown and to these arms are pivotally see the reverse movement will be held inclined,

, in the opposite direction with the result that notwithstanding alternate rotary motion, a currentof air will always be forced'in the same direction. f

It is desirable that a device of this small compass, and in order to accomplish this the spindle is made longitudinall movable throu h the journal block as be ore described. g second rin charac-- .ter should be capable of being folded in a 10 is located be neath the firstring and as a collar or sleeve 11 slidingly embracing the spindle. normally forcedaway from the first ring by It is a helical spring 12 encircling the spindle.

Each of the blade carryingarms is connectedto a ring 10 by a link 13. The spindle is provided with a knob 14 by which it ma be moved longitudinally as the grasping andles are forced together until finally the said knob engages over the ends of the handles and holds them together. In ,this position the blade carrying arms will then have been swung upon the lnner ring as a pivot until they lie close together as shown in Fig. 3. The arms may be held together against accidental displacement by a retaining device, such as 15. r

Having thus described my invention, what I claim is:

1. A toilet or hand fan eomprisin a rotary spindle, reversible fan blades carrie thereby, hand gripped levers, and means whereby the movement of said levers to and from each other rotates said spindle in opposite d1rec-. tions, substantially as described.

2. In combination, a spindle carrying elesaid spindle carrier, means whereby pindle rotatable we longitudinally movable t erein, hand levers pivotally connected 0 t e opening and closing of said hand levers oscillate the said spindle, fan blade carrying arms ivotally connected with. the spindle, and lades pivotally carried by said arms, substantially as described.

,AL In combination, a spindle carrying ele ment, a spindle journaledtherein, a Cpair of i arms n rotally connected to said spin 1 e carrylng element, a spring tending to force said arms apart, a flexible device wound upon the spindle and connected to the arms and operating upon the separation of the arms to rotate t e spindle in one direction, a spring interposed between the spindle and s indle carrier tending to rotate the spindle 1n the opposite direction, and automatically reversing fan blades carried byv the spindle, 'substantially as described.

\ 5. In combination, a spindle carrier, 11 spindle rotatably mounted therein, and means for rotating the spindle, a ring fixedly attached to the spindle, fan carrying blades pivotally-connected to said ring, a second ring movable on the spindle, and links connecting the blade carrying, arms with said ring, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALEXIS SAKOVITCH.
