1 Claim. (Cl. 40-33) This invention relates to a display device and more particularly to a device having means for providing a visual display of suitable indicia as desired.

The primary object of the present invention resides in the provision of a highly ornamental and attractive display device which will cause many individuals to give their attention to the indicia on the rotatable drum within the display device so that the sayings or advertising indicia thereon will become readily imparted to the viewer.

A further object of the present invention resides in the provision of an illuminated display device for use in conjunction with church teachings and the like which display device is in the shape of a cross having the cross arm thereof provided with a viewing aperture therethrough behind which a drum in alignment with the aperture may be rotated so that great teachings thereon may be readily imparted to the viewer.

Still further objects and features of this invention reside in the provision of a display device that is simple in construction, eflicient in use, and which is especially attractive in appearance.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this display device, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a perspective view of the invention;

Figure 2 is a vertical sectional detail view as taken along the plane of line 2-2 in Figure 1 illustrating the interior construction and particularly the drive means of the display device comprising the present invention;

Figure 3 is an enlarged sectional detail view as taken along the horizontal plane of line 33 in Figure 2 illustrating in particular the gear means interconnecting the drive shaft and driven shaft for the roller; and

Figure 4 is a sectional detail view on an enlarged scale as taken along the plane of line 4-4 in Figure 1.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates the display device of the present invention. This display device includes a base 12 of any suitable configuration from which a cruciform shaped member 14 rises upwardly. This cruciform shaped member 14 is secured to the base 12 by any suitable means. Mounted on the base 12 is a switch 16, the purpose of which will be herein defined.

The cruciform shaped member 14 includes an upright portion 16 as well as a cross arm 18. The cross arm 18 is provided with a viewing aperture 20 therein which extends substantially intermediate with one face 22 thereof. This viewing aperture is adapted to permit viewing and inspection of the indicia inscribed, printed, or otherwise applied on a drum 24, mounted by any suitable means for rotation in the cross arm 18. As shown in Figure 2, the drum 24 may include stub shafts 26 and 28 carrying pulleys 30 and 32 which are aflixed to the stub shafts. Entrained about the pulleys 30 and 32 are belts 34 and 36 which in turn are entrained about pulleys 38 and 40 carried by a drive shaft 42. Mounted on the drive shafts and held secured thereto by any suitable means is a gear 44 which in turn engages a gear 46 mounted on the end of a drive shaft 48. The drive shaft is adapted to be driven by a motor 50 mounted in the base 12 controlled by switch 16. Conductors 52 connect the motor 50 to either power or series circuits with a lamp socket 54 as may be desired, into which lamp socket a lamp bulb may be secured which lamp bulb is adapted to carrying a shade or other suitable ornamental light defiecting means, if desired. The lamp socket may be provided with its own throw switch 56 so that when the lamp socket 54 is connected in parallel with the motor 50, the circuit to the lamp may be turned off if desired without affecting the operation of the motor 50.

The drive shaft 48 may be journaled in suitable bear- 2 ing supports 60 and 62 or otherwise mounted within the upright portion 16 and the main section if such is desired.

In use, by merely turning the switch 16, the drum 24 may be rotated until the desired indicia thereon may be moved into alignment with the opening 20.

Theforegoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A display device comprising a base, a cruciform shaped member -secured to said base and rising upwardly therefrom, said member including an upright portion and a cross arm, said cross arm being hollow and having an opening in one face thereof, a drum in said cross arm in alignment with said opening, drive means for driving said drum connected thereto, said means including a motor in said base, a drive shaft driven by said motor extending upwardly within said upright portion, a driven shaft in said cross arm, gears interconnecting said drive shaft and said driven shaft, pulley means interconnecting said driven shaft and said drum, a lamp socket mounted on said member, and means connecting said lamp socket and said drive means to a source of electrical power.
