SPECIFICATION forming part of Letters Patent lilo. 793,9et2, dated July 4:, 19055.

Application filed September 1 1904. Serial No. 224,478.

.To (tZZ whom/ 11/; may concern:

ie it known that l, Sinner Unease L men, a subject of the King of Great Britain, residing at lliord, in the county of Essex, England, have invented a new and useful improvement in and Relating to Simporting Devices for .llGleetric Fans, of which the following is a specification.

This invention relates to devices for supporting electric fans, and has for its object the construction and arrangement of such apparatus whereby the electric [an an be simply and easily placed into and removed from position, its general adjustability about an axis to vary the direction 01 air-current can he easily made, and no risk exists of the fan talling out of its supporting device should the screw or other retaining device not be properly fastened.

in order that the invention may be the better 'l'mderstood, l will proceed to describe the same in relation to the accompanying drawings, reference being had to the letters marked thereon.

Like letters refer to like parts in the various .Iigures.

Figure 1 is a part-sectional view of the device with an electric fan supported thereon. Fig. 2 is a perspective view oi the part 01" the device for attachment to the wall, ceiling, or other support. Fig. 3 is a perspective view oi the part of the device attached to or forming a part of the frame holding the tan.

Upon the ordinary gimbal-lrame a oi? an electric tan 7) 1 provide a stem v, having at its outer end a projecting flange or collar (Z, and about the stem 0 is arranged a thread w. on which works an ordinary jamming-nut f. The device for carrying the fan from any llXGtl support, such as a wall or ceiling, consists of a plate or base g, having a central hole /t and a slot 7' running from the outside of the plate 5 into the central hole /t. This slot j is of such a width as to just allow the stem 0 of the fan-fran1e to pass along it easily. On the upper side of the plate (i a recess 1* is formed around the central hole In of such a diameter as to permit the flange (Z on the outer part of the :tand rame stem 0 to drop into and engage therein, so that when so engaged the tan-frame can be turned about a vertical axis in either direction, and when placed in the position in which it is to remain that position can be retained by screwing the jammingmutf along the screw-thread e until it bears against the under side of the supporting plate or base 1 as shown in Fig. 1.

Although the device has been described and illustrated for use as a hanging [itting from the under side oi a horizontal support, it is obvious the same arrangement can be used when the supporting-plate is mounted on a vertical or inclined wall or other support or .in any other equivalent position in which the fan has to be supported with its frame-stem extending in a iinore or less horizontal position. To remove the lan from its support, it is only necessary to slack the nut back sui'liciently far to permit the flange (Z being disengaged from the recess Z: of the plate ltlaving now described my invention, what I claim, and desire to secure by Letters Patent, is I A surmorting device for electric fans consisting of a supporting-base having a central a. ierturc a recess termed about said central aperture and a slot extending from the out side of the base to the central aperture in combination. with a stem adapted to pass along said slot into the central aperture a llange at the end of said stein adapted to eng with said recess and a jamming device car ried by the said stem and adapted to bear against the under side of the supporting-hase so as to lock the stem on said base subsimitially as described.

l n testimony \vhcreoil. l, have signed my name to this specification in the presence 01 two subscribing witnesses.
