ELECTRIC FAN Filed Nov. 15, 1946 Patented Feb. 20, 1951 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to electric fans, and more particularly to an electric fan of the vertical type.

A main object of the invention is to provide a novel and improved electric fan which is very simple in construction, neat in appearance, and which will efiectively distribute and circulate the air in a room in all directions from the position of the fan.

A further object of the invention is to provide an improved electric fan of the vertical axis type, said fan being very inexpensive to manufacture, efiicient in performance and quiet in operation.

Further objects and advantages of the invention will become apparent from the fOllOWiIlg description and claims, and from the accompanying drawings, wherein:

Figure 1 is an elevational view of an electric fan constructed in accordance with the present invention.

Figure 2 is an enlarged view similar to Figure 1 but with parts of the structure broken away to show the interior detailsthereof.

Figure 3 is a top plan view of the fan shown in Figure 1.

Referring to the drawings, II designates a housing comprising a relatively large circular base portion [2 upon which is secured a vertical barrel portion I3. Barrel portion l3 comprises an upper segment 22 and a lower segment 23, secured together by bolts 24 passing through the lower portion of upper segment 22 and threadedly engaging raised internal lugs carried by the upper portion of lower segment 23. Lower segment 23 has a top wall l4. Resting on said top wall I4 is a vertically positioned electric motor 15 secured to upper segment 22 by bolts 25. The shaft I6 of motor 15 coincides with the vertical axis of barrel portion I 3. The top of barrel portion I3 is open, as shown in Figure 2, and the top of motor I5 is substantially flush with the top of said barrel portion so that shaft 16 need only extend a short distance above the top of the motor. Rigidly secured tol the top end of shaft I6 is a substantially flat blade- I! of relatively large area, said blade being symmetrical with respect to its vertical axis, said vertical axis coinciding with the motor shaftaxis. Blade I! is shown as being generally oval in shape but may be varied from the shape shownso as to approach circular shape if so desired.

Rigidly secured to the top rim of barrel portion 13 is aguard l8 of wire mesh or the like which surrounds the rotating blade I! when the fan is in operation.

Barrel portion I3 is formed with a plurality of ventilating openings 19 arranged so as to permit air currents to enter said barrel portion and circulate through the motor casing to prevent excessive heating of the motor. Wall 14 is formed with a central opening 26 through which said air currents may pass into the motor casing. The ventilating currents circulate upwardly through the'-' motor casing and leave barrel portion l3 through the open top end thereof.

A control switch 2| is mounted on barrel portion [3 to turn the fan on and 011'.

While a specific embodiment of a vertically mounted electric fan has been disclosed in the foregoing description it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention other than as defined by the scope of the appended claims.

What is claimed is:

In an air-circulating fan, a base portion adapted to be supported in a horizontal plane, a vertically-disposed cup member having one end open and having the other end fixedly supported on said base portion, a horizontally-disposed wall positioned adjacent the open end of said cup member and fixedly secured to the latter, another cup member having one end open, the open end of said cup member being positioned in end to end abutting relation with respect to said first-named cup member, a vertically-disposed flat blade positioned above said last-named cup member and pivotally mounted thereon for rotation about a vertical axis, power means fixedly secured on said horizontally-disposed wall and positioned within said last-named cup member for efiectin the rotation of said blade about said vertical axis, and a cage positioned in surrounding relation with said blade and fixedly secured to said last-named cup member.
