' "HAND FAN. r

if This invention relates to a hand fan prowhen it is desired to vided with a suitable motor for operatingthe fan blades and preferably the device is of the small type so that it can be "readily carriedinthe pocket for convenient access.

One of the objects of the invention is to provide a hand fan with a spring motor which be conveniently 'woun'd up from time to time and then the spring releasedso as to rotate the fan blades when a person desires to, cool off. Another object is to provide a hand'fan of the type just mentioned with alongitudinal movable handle which may be shoved inwardly in order to wind up the motor and which-may be slid outwardly permit the motor to rotate the fan blades. v

, Other objects of the invention are to provide a convenient motor operated pocket fan cost for a device of this kind is reducedto a minimum, which may be readily operated from'tim-eto time, as desired. by a rotation of the handle whereby the entire device may be supported in one hand, and which is preferably constructed of metal so as to render it durable and to enable it to be made attractive by the use of different shapes and designs. 7 a

These being among the various objects of the present invention, thesame consists of certain features of construction and combinations ofparts to be hereinafter described and then'claimed with reference to the accompanying drawings illustrating one'embodiment of the invention, inwhich:

an opening at the back through whiohj'the various parts'of, the motor may be introduced intothe casing; The casing 10 may be of" any desired shape and may be ornamented and may be attractive in any desired manner. A mounting plate 11 is provided for supporting the elements of the gear train of the motor and also the'coiled winding spring 12. This winding spring whichcis ablyv one which requires repeated winding for temporary operation of the motor, although it is obvious that the winding spring and associated parts may be" made for: a longer period of rotationof the fan blades,

invention a different tvpe of motorrnay be employed winch may be released fromftime The primary gearl? is fixed on the drivingshaft 13. while

secondarygears

are respectively fixed on shaftsi14,i15.,.-A

bevel pinion 20 is fixed on the driving shaft 13.. while pinions 21. 22 2am respectively fixed on shafts 14. 15, 16. the said gears 17, 18, '19 and the pinions 21. 22 and 23 being meshed in well known mannerlfortransmittingthe desired power from the driving shaft13 to the ultimately driven shaft'lfi.

The winding and operatin'g' spring :12is1 "securedat its outer end to a pin 24' sup ported, from the mounting plate 11, and the inner end of said spring is secured' to. the driving" shaft 13, so that this type of power meansfor the motor may be wound up from 1 timeto time bynthe shaft 13.:and then re-' leased to expand and exert its spring power.

7 p Also fixed on winding shaft 13 is a ratchet 10 wheel 25 'having beveled' teeth which are engaged-one at a time by a'pawlor dog2 6 whichis pivotedto the large "gear 17 and whichis impelled to engage the ratchetteeth bymeans of a bowed spring 27 which'is held 5 fast at one end on said gear 17. and ,at its free end is connected with the pawl26, -'ll 1ej 1n functioniof this pawl and ratchet device spring motors is well known.

.70 and that even in some aspects of the present These parts now being described are more I30 clearly shown in Figures 4, Errand The manner of assemblingtheplate lland the gear train of the motor with and into the casing 10 will be readily understood by those skilled in spring motors. The shaft 13 turns in a bearing in the mounting plate 11, while the shafts 1st. 15 and 16 are stepped in hearings in said plate. The shaft 16 and its pinion 23 are first mounted in the bearing of the front of the casing, and then the shafts, gears and winding spring mounted on the plate ll are passed through the rear opening of the casing 10 and the shafts 13, ll, 15 finally caused to engage the step bearings of the front of the casing. Of course the parts may be assembled in other ways.

The mounting plate 11 is preferable rigid ly secured in the casing 10 in the following manner. Plate 11 is provided with an outwardly turned flange 28 which frictionally engages with the inner wall of the casing, and against the edge of said flange there is placed a back plate 29 which constitutes the back of the casing. When the back plate 29 has been introduced, the rear edge of the casing 10 is upset over the back plate 29 in the form of a flange 30. The flange 30 will thus hold the interior parts of the casing 10 in place. Other means may of course be adopted for securing the mounting plate 11 within the casing.

Inasmuch as the hand fan of the present invention is preferably of pocket size. the

fan blades

31, 32 fixed on the driven shaft 16 projecting from the casing, are of such size that they may be adapted for being folded in order to more readily go into ones pocket. Preferably to this end the fan blade 31 is composed of two sections connected by a hinge 33, so that the outer section may be folded against the fan blade It will be seen that the spring motor is of such type that the fan blades may take the position shown in Figures 2 and 3 so that the entire fan device may be readily slipped into the pocket of the one who wishes to make use of. the fan. It is preferred to make use of extremely convenient and simple means for winding up from time to time the spring of the preferred motor which has been described.

To this end the casing 10 is provided with an opening 34 which is located adjacent the driving shaft 13 and around said opening there extends outwardly from the edge of the casing a guide sleeve This sleeve extends at right angles to the winding shaft 13. A handle 36 is provided which is at least of a length so as to be conveniently grasped by the hand of the user, and this handle is preferably tubular, as shown in section in Fig. 2 and into its inner extrei'nity there is rigidly fixed a plug 37. There is a stem 38 rigidly secured in the plug 37 so that its axis and the axis of the handle are coincident, and upon the inner end of the stem 38 there is fixed a winding bevel pinion 39. Pinion 39 is adapted for engagement with bevel pinion 20 on the winding shaft 13. The handle 36 provided with a reduced end portion -10 joined with the main body of the handle by an annular shoulder 41. The reduced portion it] snugly yet loosely fits into the guide sleeve 37 so as to locate the pinion 3-) in juxtaposition to the bevel pinion 20.

Preferably the handle 36 is slidable with respect to the guide sleeve 35, into which it telescopes, and the reduced portion it) is provided with an annular groove 4;, as shown clearly in Figs. tand (i. The opposite side walls 43, a l of groove 42 provide annular abutment shoulders. and between them there projects a stop pin :5 which is rigidly fixed to the guide sleeve The abutnu-nt shoulders 43 and 44- and the stop pin to constitute means for limiting the extent of inward and outward sliding movement of the handle 36. lVhen the handle is pushed in, the winding pinion St) is brought in mesh with the bevel pinion 20, thereby to permit of the winding up of the. spring 12 when the handle 36 is rotated. It will be seen that the annular groove 4-2 permits ot' the rotation of the handle when it is in its inward position. hen the handle 36 is pulled outwardly, the pinion 239 unmeshcd from pinion 20 and the coiled spring 1:3 released, thereby operating the gear train of the motor and rapidly rotating the fan lades 31, 32 at an increased speed over the large gear 17. Thus when the pinion I3!) is released, the user, still grasping the handle so, may grasp not only the handle but the sleeve so as to hold the casing lti stationau and the user may then tal c the benctit of the breeze which is caustd by the

fans

31 and 32.

Preferably the parts of the described device are made up of metal. the casing and its parts and the handle and fan blades being of sheet metal. although it is obvious that various features of the device may be made of other material. As viewed from the outside the device is of extreme simplicity and lends itself to any desirable design, eoniignration and ornamentation and may be readily cleaned by the user by means of a pocket handkerchief. When in pocket size, as is preferred. the device is extremely com pactand is very cilicient for the desired cooling ofl" purposes. It is obvious that the described and illustrated device is capable of more or less modification without departing from the spirit of the invemion as expressed by the scope of the appended claims.
