Specification of Letters Patent..

Application led November 30, 1909, Serial No. 530,628. Renewed March 25, 1911. Serial No. 616,883. i

To all whom it may concer-n:

Be 1t known that we, 'Vicnrxn l1`. Pinn- Lnr and Ham/'nr E. BAER, citizens of the UnitedStates, and residents of Lincoln, in thecounty oi?A Lancaster' and State of Nebraska, have invented certain new and use ful Improvements in Fans, of which the following is a specification.

Our invention is an improvement in fans. and consists in certain novel constructimis and coml'iinations of parts hereinafter described and claimed.

The object of the invention is to produce a device o'f the character specified, especially adapted for use in barber shops. beauty parlors, etc., which may be held in the hand and inanil'nilated about. the 'face and hair for drying thc same, andwhich ma)1 be operated in close proxin'iity to the face or hair without danger of injury to the person operated upon,

Referring to the drawing-s forming apart lmreof:-l*`igure l ,is a side View o'F-the iinprovement. Fig. is a longitudinal sectlon. 1* 1g. 8 1s `a front View partly broken.

a "ay, and with the cover platel removed. Fig. 4 is a similar view with the cover plat-e in place. Fig. 5 is a rear view of the motor. Fig. (l is a side View of the switch, and Fig. 7 is a transverse section of the handle, on the line of they switch.

flhe embodiment. of the invention shown in the drawings is composed oi three connected portions or sections, the handle` the fan, and the operating mechanism. The handle 1' is of suitable non-conducting ma,-

yterial, such as rubber, gatta percha, Wood or 10, in the motor frame, the said frame consisting of sections 11 and 11a secured together'by screws 12, and the trarne is arranged Within a ring casingr 13. The armature shaft is freely rotatable in its bearings.

and the feed wiresv 6 and 7 are connected' with the respective brushesMand 15.-

" substai'itiallv conical perioi'ate shield llis provided with a central opening registering with the recess 2 of the handle, and with alateral flange 1T encircling the openire` and engaging' the handle. The peripheral edge of the shield is also laterally iiang'ed, as at 18. and the said flange, engages the ring casing'l of the motor.,

'l`he .tan 'consists of a hub 19 tittingon a reduced portion Q() of tlie armature shai't, and secured in Vplace by a screw E21. and a plm-alii)7 of blades 2Q extendingr radially from the hub, and twisted as shown in the usual manner. A circular cover plate 23 is inoriflcd with "a lateral marginal flange 2-*1- littin;r within the ringr casing'. and with a central (nuning'for the armature shait. and is secured to the motor frame by screws A `plurality of arms 2t) are secured to the -rinacasing' on its inner surface, and extend radially therefrom, beyondfthe ends of the fan-blades Q9.. and are then benl; laterallyY and substantially 'parallel with the axis of the arn'iature shaft, as at 30.

plurality of. rings 31 are secured to the portions 30 of the arins. in spaced relation, and a ring 2li is' secured to the radial portions. and the rings and the. arms form. a iLuard for the fan. the said `aard extending some distance in front. of 4the fan. as shown in Figs. 1 and Q, so that itwould `be iinpossible to engage the fan with the body olE the person operated upon.

The cover plate 2? before mentioned is4 also provided with perforations 32. as sh own in Fig.' 4. and While forminga shield forthe.

the air to pass therethrough,

motor, permits The to prevent overheating' -of the saine.

'pe-rforations in the shield 1G also assist in this purpose, and permity the fan to draw a current ofair through and over the motor whenever itl is in operation.

A cylindrical block 33 of insulating material -is mounted in the recess 2 on a. rod

which extends through the longitudinal' opening 4 in the handle, the outer end of the rod being` threaded and engaged by a nut 3G outside of the. casing.. The outer end of the nut is 'polygonal in cross section, and the inner end is conical, and engages a similarly shaped recess in the end of thehandle. The inner end of the rod B5 is threaded onto the end of the bearing 1() of the section 11, and is held in place by a lock nut 27. f

The end ot', the block adj aeent to the motor bears against an insulating ring 34, which 4 the rod.

encircles the rod 35,'and the ring'cngages the inner face of the recess, and the block 1s 'provided with a longitudinal groove 37. A pair of segmental shells 38 and 39 are supported on the block, and one ofthe leads or feed Wires 7 is interrupted, the ends of the Wire being secured to the respective segments.

` The segments are secured to the block by `screv'vs 40, and a rod 41, of copper-or other 'magnets 4G are also supported by the said frame. A speed regulator is also provided for the motor. The said-regulator comprises I a shoe 47 engaging an enlargement 48 'of the armature'shaft, and supported by .aresilient bar 49 secured to the motor franie by one end, as at 5.0. The free en'd ofthe bar is bent over upon itself, as at 51and a- Screw 52 is threaded through the two portions ofthe bar. i The inner .end of the screvv engages the outer face of the/shoe and presses the said shoe against ,the enlargement, when the screw is turned, and the outer end ofthe screw isprovided with a milled head 58 for convenience in manipulating' the same. It vwill be understood that the clurent'conduct-- ing ortions of the apparatus are suitably insu ated from the remainder of the'. mecha'- nism.

The bearing 10 for the armatureI sha'ft iu the section 114 of the fraaie is provided with an. Aoil 'cup 55, which extends through an Aopening in the handle; and is adapted to re eeive a lubricant, 4to lubricate the shaft.

In operation, the. improvement is grasped armature the handle l, and approached toward the The improvement is light, compact, easily,

handled`and' operated with one hand, and absolutely safe with the most carelessper! son. It may be constructed at a comparatively small cost, and since all of the arts are covered, .is not liable to become inJured or broken.

A device of the character specified, coniprising a handle having in one end a recess, a. motor casing connected with said end, a motor in the-casing, the shaft' ofsthe lnotoi extending beyond the casing. and having an enlarged port-ion in the recess, a fan detachably connectedv with the other end of the shaft, a guard for the fan comprising a cover plate secured to the casing` radialarms extending from the plate, the ends of the arm being bent laterally` substantially parallel with t-he axis of the shaft, rings secured `to the arms and encircling the fan, feed Wires extending through the handle` a switch in the recessfor connecting the Wires 'W 'Y the motor` means outside of the .handl for operating the switch. and means the enlarged portion of the shaft or regu`- .lating the speed ofthe motor.
