HAND-FAN.

Specification of Letters Patent.

Patented A11 26, 1919.

Application filed September 24, 1918. Serial No. 255,527.

To all whom it may concern Be it known that we, GEORGE FIscI-InmN and LOUIS NEWMAN, subjects of the King of Hungary, and residents of the city of New York, in the county of New York, and Bronx, respectively, and State of New York, have invented certain new and useful Improvements in Hand-Fans, of which the following is 'a specification.

The present invention relates to improvements in fans, and more particularly to a toilet-fan having a plurality of blades.

The main object of the invention is to provide a simple, efiicient and durable handoperated fan of this character, the blades of whichcan be rapidly rotated to set up an ail current, and which requires little exertion for its operation.

Another object of the invention is to provide a fan, consisting of a plurality of telescoping sections and having blades which can be folded or collapsed, whereby the device can be conveniently carried along in the pocket or hand-bag of the user.

A further object of the invention is to provide a fan of the type specified which can be manufactured on a commercial scale, or, in other words, one which is not so diillcult to make as to be beyond the reasonable cost of such a contrivance.

l/Vith these and other objects in view which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One oi the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure l is a front elevation of a fan con structed in accordance with the present invention; Fig. 2 is a similar elevation of the same, in its folded state; Fig. 3 is a section taken on line 33 of Fig. 2; Fig. 4 is a section taken through the folded fan blades and part of their actuating mechanism, on a larger scale; Fig. 5 is a section taken on line 5-5 of Fig. l-; and Fig. 6 is a section taken on line 66 of Fig. 5.

In the drawings, the numeral 10 indicates the casing of the contrivance, comprising two tubular sections 11 and 12, the former being adapted to telescope into the latter. The section 11 is closed at its upper end by a head 13 and the section 12 at its lower end by a head 14. This casing may be of a size suitable to constitute the handle of the fan and also the means for inclosing the actuating mechanism of the fan blades thereof. In the section 11 is rotatably mounted near its upper closed end a horizontally disposed tubular arbor 15, one end of which extends through the casing and is provided, outside of the said casing, with a circular flange 16, having four outwardly bent equidistantly spaced projections 17 at or near its periphery, for a purpose hereinafter to be described. Through this tubular arbor extends a spindle 1.8, the front end of which projects beyond the flange 16, while the rear end extends beyond the rear end of the tubular arbor and is disposed outside of the easing. To the rear end of the spindle is fixed a knob 19, and between this knob and the easing is disposed a washer 20, that is drawn over the said spindle. Between the washer and the knob is inserted a spring 21, coiled upon the said spindle, for a purpose hereinafter to be mentioned. The front end of the spindle 18 is reduced, as clearly shown at 22, and to this reduced end are pivoted four fan blades, 23, held upon the said spindle, for instance, by a nut 21, the threads of which mesh with threads on the reduced end of the spindle. The inner ends of these blades are disposed between the projections 17 above referred to, said projections serving to space the said blades and also as a means for transn'iitting the rotation of the tubular arbor 15 to the said blades. The spring 21, on the other hand, serves to keep the blades between the projections 17.

The driving mechanism comprises a bellcrank lever 25, that is fulorlnned at 26 to the casing section 11, and extends through an opening 27 in the said section through the casing. The outer free end of the bellcrank lever is provided with a linger piece 28, while its inner end is connected by a link 29 with a crank shaft 30, the latter being rotatably mounted in .the casing section 11. The crank shaft is connected with the tubular arbor15 by a train of" gears 31, the ratio between the gears of the Stud train being such that one revolution of the crank shaft results in a great number of revolutions of the tubular arbor and the blades connected therewith. A spring 32, bearing against the bell-crank lever anda stop 33 within the casing section 11, serves to shift the bell-crank lever'to its outer position, as will hereinafter appear.

The casing section 12 is provided with a longitudinal slot 34, through which the bell-- crank lever 25 projects.

The operation of the device is as follows :IVhen the fan is to be placed into a pocket or small satchel, the spindle 18 1S forced against the action of the spring 21 in the direction of the arrow shown in Fig. 3 of the drawings, whereby the blades 23v of the fan are disengaged from the projections 17 on the flange 16 of the tubular arbor 15. They are thus adapted to be folded substantially parallel to the longitudinal axis of the casing 10 and engage with two neighboring projections 17 when the spindle 18 is released. The tubular sect-ion 11 of the" handle is then telescoped into the section 12 thereof, the slot 34 in the latter section permitting. of such operation.

To prepare -h-e fan for use, the blades are brought into the position shown in Fig.

1 of the drawings, and the sections of the handle extended; The fan is .held in on hand of the user, who presses the thumb against the finger piece 28, forcing the same inward against the action of the spring 82, the latter causingthe lever to move outward when the finger piece is released. In

this manner the crank shaft is rotated, the fan blades through the train of gears. The blades ro-:

its rotation being imparted to tate thus at a high speed and set up a cooling current of air. To overcome the inertia of the crank shaft, it may be necessary, when starting the operation of the device, to turn the fan blades with one hand while actuatingthe bell-crank lever 25 with the other hand, until said blades act as a fly wheel for the said crank shaft.

The device is easily operated by the movement of one of the fingers of the user, or in. other words without useless exertion, which would heat the body and tire the person using the fan.

It is obvious that, while herein a particular'numberof fan blades has been referred to, any other number may be used without departing from the invention.-
