RICHARD M. CRAIG, 01? SAN ANTONIO, TEXAS, ASSIGNOR To ANIMATED COLORADVERJ TISING, INC 013' NEW YORK, N. Y., ACORPORATION OF'NEVADA i DISPLAY APPARATUS Original applicationfiled August 14,

This invention relates to displayapparatus and more particularly to an advertislng sign of the type disclosed in my Patent No. 1,698,216, issued January 8, 1929, of whlch 5 the present application constitutes a division.

One object of the invention is to provide a signwhich will be novel and attractive in appearance and hold the attention of an observer for a relatively long length'of time o and thereby serve .very effectively as an vadvertising medium. Y I

Another object of the invention is to provide a sign having an object painted thereon against a'background in different positions capable of being assumed by the object and companion lightingmeans consisting of colored lights emitting spectral rays having such relation to the-colorsused upon the sign board that as different colored lights are turned on and oif'the object will appear to change its position.

The invention is illustrated in'the accoman in drawin wherein is shown an em bodiment of the invention including a sign board and lights togetherwith a circuit for the lights. 1

In the description whichis to follow,

reference will be made to pigment colors and by this term are meant colored pigments or the colors in which the images are represented on the display surface. Where refer,- V

ence is made to spectral colors, such reference applies to" colors of the spectrum as represented by colored light rays. Refer; ence will also be made to jineutral colors,

which I employ as backgrounds, and by neutral colors I mean such as do not materially change under the spectral colors by which the imagesare displayed or, inother 7 mary colored light rays.

The drawing illustrates one embodiment of the invention and in this'embodiment the display surface is indicated by thenumeral 33 and has dark neutral background areas 34 painted thereon and red back-' ground areas35. The representation in this but the image 37 wi'llstarid outsubstantially white against the background areas 34L," When the surface is fioo'ded'with. blue light rays, the image *37 'will be obliterated'j and 1925, Serial No. 50,330. Dividedand this application filedJanuary 7, 1929. seiia in, 330,930. 1 i I i ifigureis that'ofasee-saw or a teeter-totter Vwhichfin one position of its movement is illustrated in plain white, as indicated by the numeral 36, the see-saw in this position being represented upon. the red background 35. In its other position, the see-saw or teeter-'totter is represented, as at 37, in red upon the dark neutral backgrounds 34. The

stand upon which the see-saw is supported 7 for rocking *mo'vement is represented in white, as indicated lby the numeral 38, and

islo cated betweenitwo'xof the background areas- 341- and 35,,it beingj observed that the areas '34 are diagonallyioppositely located that theareas 35 are likewise diagonal- "1y oppositelylocated. Red lightfbulbs39 and blue f'bulbs 40,1for other equivalent sources of'spectral colored light'are so arrangedwith relation'tothe display surface that the same may beflooded withred rays aorwithbluerays, and itpwill be understood that when the surface' is flooded with red light rays the image 36 will be obliterated the image 36 will standout substantially white against *the then I apparently black background 35. Under both conditions, the I support or pedestal 38 will be. visible. It I willbe understood, of course, that in this i embodiment of the inventionthe' back grounds 35 might be green and theimage' 37 might likewise be green, in which; event the image 37 would stand out under the blue I light illumination of the display surface", and the image 36 would stand out under the i'.

red light illumination'of thesurfacer; Y 7 It is, of course, essential to employ means for effecting illumination ofthe display j o surface which means will operate automati- P .cally, and inasmuch as there are many flashring devices which may be employed for this" f,

purpose, I have illustrated in coincie'ctionf with the figure a flasher indicated as a whole by-the reference'lettenA, whichfmaybe a rotary disc of insulating:material having concentric series of contact strips B andG upon its face in circuit with a shaft D which ""Q supports the disc for rotation, wires E serving to electrically connect the said contact strips and the shaft, and a conductor wire F being led from the shaft to one side of a source of current supply indicated by the numeral G. A conductor wire H leads from the other side of the source of current supply and is connected to the sockets for all of theelectric light bulbs regardless of their distinctive colors. Brushes I and J are arranged to coact respectively with the contact strips B and G, and conductor wires K and L are led respectively from the brushes'I and J and are connected, one with the other terminal of each socket for a light bulb one one color and the other with the other terminal of the socket for each light bulb otthe other color. The contact strips y B and C are arranged in staggered relation so that the circuit will be successively alternately closed through the bulbs of the two distinctive colors. 7 7

Having thus described the invention, I

' claim 1 7 Display apparatus comprising a display surface having a background a portion of the area of which is of a dark neutral color and another portion of a distinctive pigment color, the first-mentioned areabearing a representation of matter to be displayed in a distinctive pigment color, the a other area bearing similar matter to be displayed and represented in a light neutral color, and means for displaying said surface successively in the presence of contrasting spectral colors one of which corresponds substantially to the first-mentioned repre :sentation in a pigment color and the secondf,

i mentioned background area color, and the iture. 7

other of which is contrasting to the said background-area distinctive pigment color.

In testimony whereof Iafiixmy signa- RICHARD M. CRAIG, a 5.1
