CHANGEABLE SIGN.

' Application filed April 18, 1927. Serial No 184,650.

The present inventionrelates to a change able sign of the rotary type and has for its principal object to provide a structure comprising a casing with a rotatable element mounted the-rein having a plurality of illuminated signs which are brought successively in registry with a transparent paneled opening in the casing. Another very important object of the invention lies in the provision of a device of this nature whichis simple in its construction, inexpensive to manufacture, thoroughly eficient and reliable in its operation, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other ob? jects in view as will appear as the description proceeds, theinvention resides in can tain novel features of construction, and in the combination? and arrangements of parts as will be hereinafter more fully. described and claimed. v

In the drawing:

Figure 1 is a perspective view of one embodiment of the invention,

Figure 2 is a transverse section therethrough,

Figure 3 is a longitudinal section therethrough,

Figure 4 is a detail transverse section taken substantially on the line 44 of Figure 3,

Figure 5 is a transverse section taken substantially on the line 5-5 of Figure 2,

Figure 6 is a perspective view of one of the contact discs,

Figure 7 is a fragmentary perspective showing a portion of the contact ring on said disc,

Figure 8 is an enlarged detail section showing the brake structure,

Figure 9 is a perspective view of another embodiment of the invention,

Figure 10 is a longitudinal section therethrough,

Figure 11 is a fragmentary longitudinal horizontal section therethrough.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes a cylindrical casing having one end open with a hinged closure 6 therefor. This cylindrical casing is provided with a longitudinally extending opening 7. The numeral 9 denotes a drum mounted on end discs 10 and 11 and having a plurality of openings 12 with transparent panels 8'mounted therein. ne end discs 10 and 11 "are mounted on a shaft 14 contacts 22 and 23 will be in. circuit with a 7 suitable source of electrical energy. . Wires 25 and 26 are. connected respectively with rings 18 and 21 and are electrically connected with an incandescent bulb 27'carried by a bracket 28 on the shaft 14 within the drum 9. A star wheel 30'is fixed to the shaft 14 between partition 15 and the-adjacent end of the casing 5. A housing 31 is disposed in the casing adjacent the last mentioned'end and has a shaft 32 journalled therein with a worm gear 34 thereon. A crank 35 is mounted on the end of the shaft 32 for engaging the star wheel 30 so that as the shaft 31 is rotated an intermittent rotation is imparted to the shaft 14. The worm gear 34is rotated by a worm 36 fixed on a shaft 37 journalled in the housing 31 and having a pulley 38 onthe exterior end thereof to receive a belt from a suitable source such as an electric motor or other prime mover. A bralre structure is disclosed to advantage in Figure 8 and comprises a casing 40 extended through an opening in partition 16 and having a spring pressed plunger 41 therein frictionally engaged with the disc end 11.

From the above detailed description it will be-readily apparent that upon the continued rotation of the pulley 38 an intermittent rotation is imparted to the shaft 14 as explained so that the transparent panels 8 which will have suitable advertising indicia thereon will be brought successively before the opening 7 in the casing 5 so as to be visible and the incandescent bulb 27 will be out when the drum is moving and then will light as the drum comes to a standstill and of course the contacts 19 are so arranged as to accomplish this purpose.

In Figures 9 to 11 another embodimentof the invention has been disclosed wherein there is shown a casing 5 which is of a par- Y there are two drums 9 mounted in a allelopiped formation having openings or slots 7 in the ends thereof. In this casing vation in Figure 11. It is thought that this embodiment of the invention will be quite apparent without a more detailed description in View of the description of'the first embodiment.

These embodiments of the invention which I have disclosed present the invention in a very simple, eflicient and reliable manner, but nevertheless have been illustrated and described merely by way of examples since in actual practice they attain the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be quite apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is: I A device of the class described comprising ,ried by the bracket within the drum, a pair of discs on the shaft outside of the drum between one end of the drum and said other partition, a continuous conductor band on one of the discs, a plurality of spaced contacts on the other disc electrically connected together, means for electrically connecting the conductors on the discs with the incandescent bulb, brushes engageable with the conductors, a star wheel on the shaft between said closed end of the casing and said other partition, a housing within the casing at said closed end thereof, a rotatable shaft journaled in the housing, and a crank on the last mentioned shaft engageable with the star wheel for imparting an intermittent rotation to the first shaft and the drum there-- on when the second shaft is in operation.

In testimony whereof I affix my signature.

MARION R.- THROWER.
