ILLUMINATED DISPLAY DEVICE Filed Aug. 1, 1940 passes around [8 Patented Aug. 18, 1942 UNITED STATES. P TENT 1 OFFICE ILLUMINATED DISPLAY DEVICE David Wolfson, Far Rockaway, N. Y. Application August 1, 1940, Serial No. 349,070

Claims. (CL 240-101) The improvements relate to a display apparatus for producing varying colors and shades of colors upon any type of merchandise or other articles that it is desired to show to the public.

Heretofore cumbersome mechanism has been employed to give color blending effect to merchandise on display, involving sets of lights, gears, bearings, and fans. for cooling the lights when they are restricted by being enclosed in a box or projector. The present invention, however, solves these problems by utilizing a minimum of equipment and producing a maximum of efiiciency and color variation.

Referring to the drawing,

Fig. 1 is a plan view of a display apparatus with the cover removed, embodying the improvements;

Fig, 2 is a front elevation of the display box showing merchandise in place for lighting;

Fig. 3 is a perspective of an alternate method of using the display apparatus; and

Fig. l is a plan of a modification showing the lighting and drive mechanism.

l is the box or housing within which the mechanism operates. 2 is the top of the box which is hinged at 3 and has openings 4 to allow the light to shine through on the merchandise 5 placed above the holes 4. The front of the box has a rectangular opening 6 which has afiixed on three sides an angle strip 1 into which may be dropped any type of partially translucent ma-' terial containing advertising or other reading matter. Run through the box I at the rear is ed on it vari-colored strips 20, 2|, 22 and 23 which are formed in spirals.

The operation of the display device is as follows:

The switch 8-is thrown, this lights up the element-l3 and starts the pulley wheel l5 and pulley belt [9 passing over the grooved collar Hi the colored cylinder [6 is slowly revolved, the merchandise to be displayed having been previously set or being now set over the holes of the hinged top 2. The light therefore passes from the lighting element I3 through the cylinder I6 and out through the holes 4 and is cast upon the merchandise. Due to the spiraling of the different strips of color 20, 2|, 22

and 23 on the cylinder I 6 one end of the box I will be showing one color while the other end shows a different color and all in between the two will be a blend of colors which are slowly changing.

Fig. 3 shows the hinged lid 2 lifted slightly and held in place by the brace 24 so that the light is reflected from the bottom of the lid 2 directly onto merchandise placed behind the box. In this use the openings of the cover may be closed in a suitable manner.

In Fig. 4 we see a modification in which the divided into two sections lGa and I 622 and to the pulley wheel l5 hasbeen added a pulley wheel together with an additional pulley belt I911. The

V purpose of this is to produce blends of color an electric switch 8 and an electrical inlet 9.

Positioned within the box are a transformer l0, electrical plug contacts II and I2, a cold lighting element l3, which runs the length of the box from the plug H to the plug I2. It will be here noted that a change oflighting elements may be quickly accomplished by merely lifting the lighting element [3 from the sockets l I and I2 and inserting a new one in its place, II and i2 are open at the top.

At the rear of the box I and at one end is located a small geared motor M with a pulley IS on its shaft; Journaled on the lighting element I3 and using it as a bearing is the cylinder l6 which has at its ends metal collars l1 and I8 fitting loosely around the lighting element allowing free and easy rotation of the cylinder l6 thereon. The collar I8 is grooved at its inner end to receive the elastic pulley belt l9 which and around the motor pulley I5. The cylinder I6 is made of transparent or translucent material and has impressed or paintwhich vary infinitely the same hues and shades obtainable thereby being varied as the cylinders l6 and to the What I claim is:

16a will not rotate at the same speed due different diameters of the pulleys l5 and 1. In a, lighting display device'of the type de-' scribed, a translucent cylinder and means for rotating the same, tubular means for producing light, said tubular means being within said cylinder and said cylinder being rotatably support.- ed thereon, and means for directing light through said cylinder and on articles to be displayed, said illuminating tube projecting beyond the ends of said cylinder.

2. In a lighting display device of the type described, a translucent cylinder and means for rotating the same, tubular means for producing light, said tubular means being within said cylinder and said cylinder being rotatably supported thereon, and means for directing light through said cylinder and on articles to be dis-- played, said illuminating tube projecting beyond motor [4. Through the- I511 of a greater diameter the ends 0! said cylinder said cylinder having direct bearing thereon.

3. In a lighting display device or the type described, a translucent cylinder and means for rotating the same, tubular means for producing light, said tubular means being within said cylinder and said cylinder being rotatably supported thereon, and means for directing light through said cylinder and on articles to be displayed, said illuminating tube projecting beyond the ends of said cylinder and projecting light beyond the ends thereof.

4. In a, device or the character described an attenuated illuminating tube providing a source of light, a plurality of light transmitting cylinders Journaled thereon and means ior rotating said cylinders at diflerent speeds, said cylinders having vari-colored spirate translucent strips thereon. I

5. In a device of the character described an attenuated illuminating tube providing a source 01' light, a plurality of light transmitting cylinders journaled thereon and means for rotating said cylinders at different speeds irom a common source of power, said cylinders having colored translucent zones thereon.
