PORTABLE FAN Filed Jan. ll, 1954 INVENTOR ATTORNEYS United ,States Patent Oce 2,759,714 Patented Aug. 21, 1956 PORTABLE FAN Gilbert I. Ayup, Eloy, Ariz. Application January 11, 1954, Serial No. 403,221 2 Claims. (Cl. 261-24) This invention relates to a portable fan, and has as its primary object the provision of a battery-powered fan which may be carried about by an individual for personal cooling.

An additional object of the invention is the provision of such a fan which may be powered by a dry cell such as a flashlight battery or the like which may be carried in the individuals pocket.

Still another object of the invention is the provision of a portable fan of thisy character which is provided with means for humidifying the air circulated thereby,

A still further object of the invention is the provision of a fan of this character wherein the moisture containing humidifying elements are positioned so as to be readily accessible for remoistening or replacement as desired.

Still another object of the invention is the provision of such a fan which is sturdy and durable in construction, reliable and efficient in operation, and relatively simple and inexpensive to manufacture and assemble.

Other objects will in part be obvious and in part be pointed out as the disclosure of the invention proceeds, and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawings:

Figure l is a front plan View of one form of device embodying features of the instant invention, certain concealed portions thereof being indicated in dotted lines.

Figure 2 is an enlarged sectional view taken substantially along the line 2 2 of Figure 1 as viewed in the direction indicated by the arrows.

Figure 3 is a sectional view taken substantially along the line 3-3 of Figure 2 as viewed in the direction indicated by the arrows, and

Figure 4 is a schematic view of a wiring diagram of the circuit of the device.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Referring now to the drawings in detail there is generally indicated at a fan housing, which includes an outer casing having a bottom wall 11, a rear wall 12 and a top wall 13 hingedly connected as by hinge member 14 to rear wall 12.

As best shown in Figure 3, casing 10 also includes apertured side walls 15, including relatively large apertures 16.

An inner container 17 is also provided, and includes a rear wall 18, bottom wall 19, and top wall 20. Bottom wall 19 and top wall 20 are provided respectively with an upwardly extending ange 21 and a depending ange 22. Inner container 17 also includes side walls 23, apertured as at 24, and having inwardly extending side flanges 25. Cross-bars 26 and 27 extend from top and bottom flanges v21 and 22, and side ilanges 25 respectively, intersecting at the center of the front of the casing and provided with a journal 30 for a shaft 31, the rear end of which forms the drive shaft of an electric motor 32 of any desired conventional construction. Motor 32 is supported on a llange 33 carried by a bushing 34, which engages the threaded end 35 of a handle portion 36, handle 36 being tubular and serving as a conduit for current carrying conduit 37.

An outer threaded bushing 38 serves clampingly to secure bushing 34 and handle 36 in related assembly with inner and outer casings 10 and 17, respectively.

Shaft 31 carries a fan hub 40, from which radiate blades 41 of any desired number and conventional configuration.

Sheets 42 of pervious material are adapted to be positioned between inner and outer side walls 23 and 15, respectively and when suitably saturated with moisture serve to humidify air drawn into the sides of casing 10 by fan blades 41, which cooled and moistened air is then blown outwardly through the open front of the casing.

Conduit 37 leads to an inlet 45 of a battery box 46, which contains suitable batteries 47 of any conventional type, the box being provided if desired with a carrying handle 48, the ends of which are mounted in suitable journals 49 carried by the top of battery casing 46. A conventional two-position switch 50 is also provided, preferably on the top of battery casing 46.

As best shown in Figure 4 conduit 37 contains hot and cold lines 51 and 52 respectively, the cold line 52 leading from one terminal 53 of switch 50 to battery 47, and thence to one terminal 54 of motor 32, from the other terminal 55 of which hot line 51 leads to the other terminal 56 of switch 50. Obviously when switch 50 is closed the motor 32 is energized to rotate the fan hub 40 and hence fan blades 41.

The hinged top wall or cover of outer casing permits the pervious sheets 42 to be readily removed from the Space between outer Walls 15 and inner walls 23 for remoistening or replacement as may be desired. Equally obviously the device may be made in any desired convenient size for ready portability.

From the foregoing it will now be seen that there is herein provided an improved portable electric fan for personal use which accomplishes all the objects of this invention and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:
