Dec. 24, 1929. w. E. PRICE ELECTRIC LIGHTED DISPLAY SIGN OR EMBLEM Filed April 30. 1926 I INVENTOR M/fiamf. B4612 BY ATTORNEY Patented Dec. 24, 1929 UNITED STATES WILLIAM E. PRICE, OF WHITE PLAINS, NEW YORK ELECTRIC-LIGHTED DISPLAY SIGN OR EMBLEM Application filed April 30, 1926. Serial No. 105,663.

This invention relates to electric display devices, such as electric signs for commercial and ornamental purposes.

An object of the invention is the provision of a practical portable device for displaying an electric lighted flag or like emblem, or decoration, which device shall be simple in construction, comparatively cheap to manufacture, and eflicient in operation to a high deembodiments of this invention,

Fig. 1 is a front elevational view of the device, partly broken away to show the interior construction,

Fig. 2 is a cross sectional view taken on line o 22 in Fig. 1, and

Fig. 3 is a fragmentar cross sectional view showing a modified form of. light changing mechanism.

Referring in detail to the drawing, 10 denotes an electric lighted display device embodying the invention. As here shown, the same is seen to comprise a box-like casing 11, preferably of triangular cross-section, mounted in an overhanging position to extend outwardly from a vertically disposed tubular stanchion 12, supported on a suitable base member 13.

Said casing 11 may be constructed in any suitable manner, and may be either molded or made of sheet metal and have openings 14% in opposite enclosing sides thereof to serve as frames 14, wherein are fitted translucent signs or emblems 15 as for example, American flags. The signs or emblems 15 may be painted or otherwise formed on glass, celluloid or other like sheet material, or may be constructed of printed or woven textile fabrics, said sign preferably being removable from said frame openings 14? to permit interchanging thereof. The casing 11 may be secured to the stanchion 12 by a demountable support of any suitable construction for easily separating the several parts in shipping and transporting of the device. As here shown, said demountable support comprises a slideway frame member 16 fastened to extend along the exterior rim portions of an opening 12 provided to (BX-I tend lengthwise of said stanchion 12. Said slideway frame member is adapted to receive out-turned edge flanges 11 formed on an open end of the casing 11 for retaining said open end in registry with the stanchion opening 12 Mounted within the stanchion 11 is an electric light socket 17 having a bulb 18, the lat- 5 ter being connected through any suitable means, such as conducting wires 19 and an attachment fitting 20 to a suitable electric power source (not shown). The bulb 18 is preferably arranged to transmit the light uni- 7 formly through the openings 12 into the casing for illuminating the emblems 15.

If desired,the lighting efliciency may be improved by providing a suitable reflecting surface or reflector 21 along the inner surface of the stanchion 11 about the bulb l8 and adj acent the opening 12. To further intensify the illumination on the signs 15, a suitable lens 22 may be interposed in the said opening 12. Said lens may have its surface 22 ribbed for further refracting and uniformly distributing the light rays from the bulb 18 over the inner surfaces of the signs 15.

F or giving a novel lighting effect to the sign as for example to effect the simulation of a waving flag, a suitable light intensity changing mechanism is provided. Said mechanism may be operated in any suitable manner and for simplicity and economy as shown in Figs. 1 and 2, is seen to comprise a heat motor having the propeller 23 pivoted on the tip of the bulb 18, said propeller having depending therefrom a tubular covering 24 surrounding the bulb 18. The covering 2 1 may be made of a suitable translucent sheet material such as paper or silk, painted or otherwise decorated to color or to subdue to Various degrees the light passing there through whereby the lighting eflects on the flags 15 are kept continuously changing on rotation of the propeller so as to produce the simulation of the waving of the flag 15. With the form of heat-motor described above, one or more air inlet openings 25 are provided in the stanchion 12 below the bulb 18, and one or more outlet air openings 26 in a ball cap 29 forming the closure on the top or free end of the stanchion. Said ball is preferably demountably secured in position to permit the replacement and removal of the bulb 18 and the light quality changing mechanism. In the above described construction of the device 10, the stanchion 12 is preferably made of opaque material to conceal from view the lighting source and said mechanism.

The operation of the device 10 will now be made clear. After assembling the parts as shown in Figs. 1 and 2, the device is attached to a suitable electric power source for lighting the bulb. The air surrounding the latter will be heated and in rising through the propeller 23 will cause the same to rotate and carry the covering at around therewith. Direct rays of the light from the bulb together with rays from the reflector 21 pass through the lens 22 and are directed to uniformly illuminate the emblems 15. The sides of the casing 11 carrying the emblems are prefer ably set in an angular position relative to a central line AA, (see Fig. 2) which passes centrally through the bulb 18 and the lens 22 so as to bring the emblems in the direct path of the light rays, the surface 22 of said lens being shaped to uniformly distribute the light over the surface of each of said emblems 15.

The heated air inside the stanchion passes out through the outlet openings 26 and cool air is drawn in at the inlet openings 25 thereby causing a continuous flow of air through the stanchion for keeping the propeller in motion as will be well understood. The covering 24 serves to vary the intensity or color of the light projected therethrough from the I bulb 18.

In shipping or transporting said device 10,

'the parts may be easily disassembled by dismounting the ball cap 29 for removing the I propeller 23, covering 24 and the bulb 18, and

3 quality changing mechanism which is seen to comprise a fan 123 driven by a motor 124 which is preferably positioned in the base 13, the fan being adapted to blow air supplied through inlets 25 up through the stanchion and around the bulb 18. Loosely suspended from suitable fittings 125 and surrounding the bulb 18, there are provided streamers 126 formed of suitable opaque or translucent material, each of the latter preferably being weighted at its lower end. When the motor 124: is operated to rotate the fan 123, air is forced up through the stanchion 12 and is effective to blow the streamers about. The irregular movement of the streamers intercepts the light from the bulb and varies the intensity and color of the light projected on the emblems 15.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not ina limiting sense.
