CONVERTIBLE FAN.

Application filed April 2, 1921. Serial No. 453,144.

To all whom it may concern Be it known thatI, DU VAL Q. HICKS, a citizen of the United States, residing at F redericksburg, in the county of Spottsyl- Vania. State'ofVirginia, have invented cer-.

as a grindstone, an egg beater, a butfing wheel or the like. I

At the present time, the ordinary household fan is used during the summer months only, beinguseless for any other purpose.

An object of this invention is to provide such a fan :soJtha't it can bequickly and easily converted into a device for drlving any rotative instrument, such as a grindstone, buffer Wheel, agitator or the like.

provide a quick detachable connection be- 1 tween the fan guard and the motor casing whereby the fan guard may be removed 1ndependently of the fan. s

A further object of this invention is to provide a combined fan and agitat ng device constructed so that the fan and fan guard may be removed and replaced by position without substantially lowering the working end of the motor shaft sothat the agitator attached thereto can project into a relatively deep receptacle supported on the fan base.-

A further object ofkthis'invention is to provide a simple and inexpensive convertible fan ofthecharacter described.

saera In general, the fan comprises a support upon which an electric motor is mounted.

The motor is adapted to receive andydrive a fan shaft, and to this end is formed in' any desired manner, with a quick detachable connection for the fan shaft so that the fan may be removed and replaced by a suitably driven lnstrument" such as a. gr1ndstone,buffer wheel or agitator. When using the motor for driving a fan, thereis provided a fan guard, which at 'theback is ding strips detachably slidformed with gui mg in guides formed on the'motoli casing. In this manner, the fan and guard may be quickly detached and the desired instrument quickly connected to -the motor shaft; The motor is pivoted to it'ssupport-so that fan driving position to tical agitator driving mounting, of the motor located so that t the motor shaft reason of th it can swin from a substantially horizontal substantially verposition. The pivotal on the upright is he detachable connectionof is not substantially lowered e shifting movements. As

downwardly into or the receptacle.

too' near the mouth of It is furthermore evident that by means'of this construction, I combine in one apparatus, a fan driving device in wh ch the motor is mounted relatively low with respect to its supporting upright and also an agitating device in which the motor 15 mounted relatively high with respect to the base upon which the receptacle is to be seated, and furthermore, the motor shaft shifted into a position substantially over the receptacle seat so that the agitator attachment can easily project into and will be located centrally of the receptacle.

Referring more articularly to the accompanying drawings, the device comprises a support or base 1 provided at its upper end with bifurcation having bolted thereto a bracket 3 which in the present form, extends forwardly over a front part lof the base. This bracket 3 at its upper end is likewise bifurcated as at 5 to receive a lug 6 integral with the motor casing. The lugs 5 and 6 form a pivotal mounting 7 so that the motor can swing from a substantially horizontal position to a substantially vertical position. In the horizontal position, the motor casing 8 of any desired construction, rests on the top of an adjusting screw 9 threading into the upper portion of the base 1. In the vertical position, the motor is held by means of the lug 6 nesting in the bottom of the bifurcation 5 on the bracket 3. It is obvious that any desired manner of pivotally mounting the motor on this bracket and holding it in both horizontal and vertical positions may be utilized. At one end the motor 10 is provided with a handle 11 in the form of a knob and with an oil cup 12. At the opposite end the motor is provided with an oil cup 13 mounted on a boss 14 from which the motor shaft 15 projects. In order to quickly convert the fan into a means for rotatably driving any desired attachment. the motor shaft 15 is formed with a quick-detachable connection for the fan or attachment. A simple and preferred form comprises a sleeve 16 attached to the outer end of the shaft 15 as by means of the screw 17 and the outer end of this sleeve is provided with a slot 18 adapted to receive a pin 19 formed on the periphery of the fan shaft so that when the fan shaft is telescoped into the sleeve 16, the pin 19 will freely engage into the slot 18 to form a rotative driving connection. In order to prevent endwise movement of the fan shaft out of this sleeve, a spring 20 is fastened to the periphery of the sleeve and is provided with a detent 21 adapted to engage over the shoulder on the pin 19. By this means, the fan may be quickly detached from the motor shaft and replaced by the grinding or buffing instruments shown in Fig. 8 or by the agitator shown in Fig. 9. The pin 19 curves on its inner face so that the spring detent 21 will ride over the face and snap over the shoulder thereof.

. In order to remove the fan, it is of course first necessary .to remove the fan guard, and

to this end, the fan guard 22. which may be formed of any desired material and of the usual approved construction is provided with an open peripheral portion 23 at its base, in the present instance formed by omitting several of the peripheral cross wires 2a so that the fan guard can be lifted vertically clear of the fan. Instead of forming the back of the fan in the usual manner, I have provided it with a means whereby it can be quickly detached from the motor casing. The preferred form is shown in Fig. 6 and comprises a frame formed of two guide strips 25 and 26 which, at their intermediate portions, are arranged parallel and are connected by a cross piece 27 preferably attached thereto by welding. These guide strips 25 and 26 are inclined outwardly at their outer ends and are attached to the peripheral portion of the fan guard by riveting as at 28. The guides adapted to receive these guide strips 25 and 26 are formed on the front face of the. motor casing. The preferred form of one of these guides is shown particularly in Fig. 4 and comprises a sheet metal clip 29 having upper and lower tongues 30 and 31 for attachment to the motor casing.

wardly to provide a folded over portion 32. These two clips are held in spaced relation on the front part of the motor so that when the guard frame is held above the fan, it may be passed downwardly over the fan, the guide strips 25 and 26 sliding through the spaced folds 32 of the clips 29.

When it is desired to use the motor as an agitator, the guard and fan are removed as before described, and the agitator tool 23 shown in Fig. 9 is quickly attached to the motor shaft. Particular attention is directed to the fact that by pivoting the motor at a point substantially over the receptacle seat 4: and by locatingthe pivot on the motor at a point substantially under the end of the motor shaft,-the end of the motor shaft is not substantially lowered when the motor is swung into vertical position. This construct-ion permits the use of a relatively deep receptacle and allows a relatively long-handled agitator attachment, articularly desirable in beating eggs, cream and the like. The motor is now shifted into vertical position and at the same time the agitating receptacle 34lis placed in a cut away or recessed portion 35 on the support 1 so that the agitator 33 and receptacle assume the position shown in Fig 9. If preferred, the agitator receptacle 34 may be provided with spring clips 36 which pass around the upper portion of the support 1 so that the receptacle is held in position. It is further to be noted that the receptacle is provided with an inverted cone-shaped bottom 36' so that the contents are confined in At the in termediate portion, the clip 29 is bent forthe central portion ofthe receptacle. Thisis particularly desirable when it is necessary to beat a single egg. If deslred, a cover 37 may be provided for thereceptacle which is slitted for the reception of the agitator shaft.

, It will be obvious that minor changes in the details of construction and the arrangement of the parts may be made without de- 1 parting from the spirit of the invention as connection between said motor shaft and said fan, a fan guard provided with an open peripheral portion and a pair of spaced guidestrips adapted to fit into said guideways on said motor whereby said fan guard may be quickly detached from said fan.
