Application filed March 10, 1925. Serial No. 14.492.

This invention relates to electric fans and-pertains particularly to an electric fan horizontally and downwardly therefrom.

The invention contemplates the. provision of aminiature airplane and a suspension rod adapted to have one end fixed tov the ceiling and extending through the bodyof the plane upon the longitudinal center thereof, and secured at the lower end against the underside of the body in such a. way that the body will be capable of revolution about the suspension bar. The plane is provided with vertical and horizontal tail rudders the vertical rudder being set at an angle so that air currents created by a fan mounted upon an electric motor positioned upon the forward partof the fuselage of the plane, will strike the rudder and cause the plane to revolve upon a support. The wings of the plane are provided with air deflectin means whereby the air currents set up by the fan at the forward end of the plane will be partly deflected downwardly from the body ofthe plane.

A further and final object of this inven tion is the provision, in a manner 'as here inafter set forth, of an electric fan comprising an airplane in miniature, having a light means thereon and designed to be attractive in appearance and efficient in operation.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming-a part of this specification, with the understanding that the invention is not confined. to any strict conformity with the showing of the drawing, but may be changed andmodified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Fig. 1 is a side elevation of the fan structure embodying this invention. I

Fig. 2 is a top plan view of the same.

Fig. 3 is a front elevation of the same.

'8 thereof beingsecureci representation of the airplane.

Fig.- 4 is the horizontal section between I the wings of the plane lookingup toward the underside of the 'top wing.

Fig. 5 is a section taken upon the line 5.5 of Fig. 1. p

Referring now to the drawings in detail wherein like numeralsof, reference indicates corresponding parts throughout the several views, the device embodying this invention comprises a'miniature airplanehav ing. the. fuselage 1. Extending across thefor'ward portion of the fuselage 1 is a pair of spaced superposed top and bottom wings 2 and lower "wing 3 extends beneath'the fuselage 1 andthefuselage is terminated adjacent the front edges of the wings, and has ex- 3 respectively. held in spaced 7o relation by the vertical standards 4. The

tending from its lower portion the platform or extension 5. At the rear of the fuselage there is placed verticaland horizontal steering rudders 6 and 7 respectively, the rudder 6 being in two ortions, the portion to and with respect to the portions 6 by means of the angle brackets 9. Secured to the-underside of the plane are a pair of depending arms 10 carrying there. between an wheels '12 are supported to complete the Adjacent the rear edge of the upper and lower planes 2and 3 upon each side of the fuselage, and held adjacent wing to-set up air deflecting members. The members 13 which are cut from the upper wing 2 extend downwardly and rearwardly as indicated in Figure 1 and'are held in this downwardly angled position by the brackets 14. The lower members 15 extend upwardly. and inwardly above the lower Wing 3 as shown in Figure l, and are held in this upward extending position by the members or brackets 16. The lower. members 15 are thus supported at an angle above openings 17 in the lower wing'of the plane.

Mounted upon the extension or platform 5 at the front end is the electric motor 18 having the usual shaft 19, which .shaft ex tends longitudinally of the body of, the plane, and has fixed thereon the propeller or fan blades 20. v

Although this plane might be supported in any suitable manner by a suspension bar at an obtuse angle .aXle 11 on which a pair of a section is cut out of the plane I at an angle withrespect to the 21, the upper end 22 of which is adapted to be secured to a ceiling, and the lower portion of the suspension rod extends through the longitudinal centerof the wings and fuselage and extends beyond the underneath side'tliereof and has threaded upon its low- "ber 23 carries a series of friction balls 24:.

plane fuselage; The plane is thus directly supported upon the ball members 24 and'23- er ends beneath the fuselage the portion 23 of a ball race member. This ball race mem which is secured'to the lower end of the suspension rod 21, to revolve thereabout.

The suspensionrod 22 is hollow as shown -in Fig. 5 and has passed therethrough an electrical conducting element 27 which eX- tends through an aperture 28 in the rod 21 into the interior of the fuselage-1 to, feed current'to the motor 18 through the following means. p

The rod 21, within the fuselage 1 has secured thereabout the annular current'distributing members 29 and 30 respectively.

The upper member 29 has a binding post31 thereon to which one of the current bearing conductors is secured. The member 3 alsohas thereon a binding post 32 to which the other electrical conductor is attached. 7

Secured to one inner side of the body 1 is a pairof contact brush fingers 33 and 34 respectively, the brush 33 bearing or rubbing against the annular distributor 29 and the brush 34 bearing'against the distributor.

30. Binding posts 35 are mounted at the fixed end of the brushes 33 and 34 and to these binding posts the. ends of electrical conducting elements 36- are secured, and through-these elements the current is con- -ducted to the motor 18. An electric light socket may be mounted at the lower end of the suspension tube 21 as indicated at 37 and an electric light 38 mounted therein, and other sockets may be mounted upon the lower wing 3 as indicated at 39 for the mountingof light bulbs 40 upon the wings.

These bulbs may be lighted through current conductors 27 and the fan may thus bemade to give 1i ht as well. Y

It will e seen that when the electric mott'or is started the air currents set up by the :fan 20 will be directed backwardly to or between the wings 2 and 3, some of the currents strike the deflecting members 13 and 15 and to be sent downwardly from the fan while the balance of the current impinges uponthe rudder 8, thus causing the plane to revolve upon the friction balls 24 and while the fan 20 is in motion this revolving of theflplane will continue.

From the foregoing description'itcan'be readily seen that there has been constructed an unique and novelfan structure, which will be both effective and attractive.

Having thus described my invention what I claim is: a

,1. In a hanging fan of the character set forth, 'a' suspension bar ca. body revolubly supported intermediate its ends, on said bar. a fan structure mounted upon one end of said body, laterally extending elements carried by said body having means for deflecting downwardly a portion of the air currents thrown backwardly by said fan, and meansupon the rear of said body, adapted to be acted upon by air currents from said 1Cfjin, to cause the body to revolve about said 2. In a hanging revolublc fan of the character set forth, a vertical suspension bar, a body structure having said bar extended therethrough, a pair of bearing separated ball races one secured to the underside of said body and traversed by said bar and the other secured to and about said bar, a

fan structure carried by said body, and

means attached to said body for deflectin air currents downwardly therefrom an simultaneously causing the body to revolve on said bearings, 1
