(Cl. l0-132) In most such instances, however, and even in the case of large outdoor advertising signs, too little attention has been paid to the proper harmony of colors to gain and hold the attention of the viewers. It is the appreciation of this, resulting in the' harnessing of the effectiveness of color and the utilization `of it in simple, concentrated manner which, taken alternatively with the message to be delivered, form the basis of this invention. In addition to the right color harmony to have the most effective appeal, the invention also contemplates the combining of the same with music, appropriately Written or selected, to t the mood that is'created by the color presentation. v To be more specific, the invention contemplates the high intensity propagation of a light beam resulting from the reiiection of light from a plurality of color discs in juxtaposed relation and rotating at high speeds.- It has been found, in accordance with the invention7 that if such discs have the surfaces thereof formed throughout \-into equal alternating segments of the primary colors, red, blue 'and'greem and if the discs are all rotated at the same high speed, a ood of lconstantly changing color will result whichevvill have an impelling attractiveness for the passerby. This attractiveness, whether or not coupled with suitable music, can then be used in sudden alternating relationship with message means supplanting it to put the message across to the observer in a most striking manner. Generally Vespeakinggthe invention contemplates the achieving of its end by the positioning of the color discs and light sources of adequate intensity on one side of a half silvered mirror, or similar semi-light transmissive, semi-light reflective element, while incorporating, inthat element, the sign to ibe displayed. Then when other light sources of suitable intensity are provided on the opposite side of the half silvered mirror and means are provided for alternately cutting off the light behind the mirror projected on to the discs then turning on the light directed against the outer face of the mirror, the switch can be made back and forth from the appeal of the flood of color to the transmission of the message and vice versa. -It is accordingly an object of this invention to improve upon the attraction aspect of changeable exhibits or signs. `Another object is to do so in a simple, economical manner. Y Another object is to do so by means of a simple readily portable mechanism, complete in itself, calling for no particular installation. A further object is to provide for a iiood of colored light of rapidly and continuously changing characteristics. A further object is to provide a combination of such light with appropriate sound. A still further object is to combine the showing of assises Patented Aug. 28, 1962 YVwith the acpmpanyingpdgwing, proceeds. vIn that drawing; FIG. 1 is a side elevation of a housing containing display mechanism in accordance with the invention, with the side wall removed .to show the elements of the invention contained therein. FIG. 2 is a vertical section of the housing of FIG. 1, taken on line 2 2 of FIG. l, looking in the direction of the arrows. FIG. 3 is a view similar to FIG. l of a somewhat moditied `form of the invention. FIG. 4 is a vertical section thereof taken on line 4 4 of FIG. 3 and looking in the direction of the arrows. FIG. 5 is an enlarged fragmentary elevational view of a plurality of discs in accordance with a modied form of the invention, illustrating the driving of the same. 'FG 6 is a sectional view taken on line `6-6 of FIG. 5 and looking in the direction of the arrows. IFIG. 7 is a front elevational view of a display screen in accordance with the invention; and FIGS. 8 and 9 are fragmentary sections of material for lforming the display screen of FIG. 7, illustrating various manners for the make-up of the same. In the accompanying vdrawing the invention is illustrated as 1being embodied in the display cabinet which accommodates all the -apparatus of the invention. It is to be understood, however, that such showing is purely for illustrative purposes, since the invention can be ernbodied in cabinets of a wide variety of shapes and sizes and, in fact, can be made up in displays which need no cabinet or surrounding `at all. Furthermore, though various mechanical expedients have been shown for the correlating and driving of the various elements of the invention, it is likewise to be understood that these are merely illustrative of simple means for the carrying out of the invention. Various other forms of drives and monntings, whether mechanical, electrical or uid, can be employed in connection with the invention if desired. Considering then the illustrated embodiment of the invention, the operating elements are shown as enclosed in a housing .or`cabinet, generally indicated at 1, having top and bottom. walls 2 and iA respectively, side walls 4 and 5 respectively, and a back wall 6, leaving the front 7, opposite the Wall 6, open. Inside of the cabinet the rear part, towards the Wall 6, accommodates the colored discs and drive mechanism therefor, generally indicated at i8, while spaced downwardly therefor are a plurality of light sources 9 and 10. As here shown these`\lights are applied to the top and bottom Walls of the cabinet but may alternately or additionally be applied to the side walls 4 and 5. Next, outwardly from this set of light sources, is the display screen or Window 11, which preferably encloses or\is,olates the open front of the cabinet from the interior thereof. Finally the walls of the cabinet, outwardly of the screen 11, are employed for the mounting of additional light sources such as 12 and 13. Reverting to the color reflecting discs and drive mechanisrn therefor, all as generally indicated at 8, there are preferably vfour Such discs as shown at 15, 16, 17V and 18, so mountedin overlapping relationship, that there are the open spaces inwardly between the discs 15, 16 and 17 are not visible from the window side. The discs 15 to 18 are mounted on parallel shafts 20, 21, 22 and 23, each of which is suitably mounted with respect to the wall of the housing by brackets such as those shown at 24 and 25 for the shaft l20. Each bracket carries a suitable bearing member such as those shown at 26 and 27, which are preferably of ball-bearing or other frictionless type, inasmuch as the discs are intended to be driven at high speed and to operate for long times at a stretch. Similar brackets and bearings, as shown, Yare employed for the other shafts, but need not be detailed here. In the form of FIGS. l and 2 the drive of the shafts is effected from the motor 27 mounted on the bottom 3 of the housing and driving the shaft 23 by means of I etiveiy-tenthe motor shaft and to the aft 23 'f rotate therewith. Drive from the shaft 23 tti/'maiis 20, 21 and 22 is here shown as effected by a series of gears, all of the same size, so that the discs will all be driven at the same speed. The drive gear 31 is secured to the shaft 23 and meshes with the gears 32, 33 and 34, keyed to the other shafts in order to drive those shafts. The gears 31 through 34 are preferably of lightweight inexpensive construction to keep both the cost andweight of the assembly down as well as keeping down the inertiia factor in the driving mechanism. Y The discs through 18 are, of course, secured toV their respective shafts to turn therewith and, like the gears, are of light weight construction, for they are intended to rotate at high speed. In this regard it is to be noted that the drive for the discs, here exemplified by the electric motor 27', should be a high speed device since, Ifor best results, the discs should be rotated at high speeds. Variations in the speed, to give variations in the color effects, are also contemplated, particularly where the motor speed can be varied automatically. In the course of the operation it is contemplated that, for a certain period of time the motor will run at maximum speedl and then, by an automatic control, will have its speed stepped down for time increments, which control will re-cycle itself as time goes on. Timing devices, to eiect such variations in the operation, are well known and do not, in and of themselves, form any particular part ofthe invention, so it is not thought necessary to make any more than a token showing, the same as at 38. To give the pronounced color effects desired by the invention, each of the discs is divided, throughout its surface, into segments of equal size. Each three adjoining segments make up a section, the segments of which are each respectively colored with one of the primary colors, i.e., red, blue and green. This pattern of sections repeats throughout all of the discs so that the same arrangement of colors prevails on the faces of all vof the discs. Considering that the discs are to be driven at high speed, the segments should not be so small that the differences between sets of them become indistinguishable. On the other hand a reasonably large number of segan illustration, Where the segments 3S, 36 and 37, color/eid respectively, red, blue and green, each take,np/10 of the arch of the circle, each section Would/take up of the total area. Thus twelve such sets would be applied to the disc and the same pattern arrangement would be followed throughout all of the dscs/ f To produce the desired display eiiect, strong illumination from lightggources, such as 9 and 10 in FIG. 1, is diretedonth'e faces of the discs. vThis light must be intense and its beam be directed or focused onto the faces of the discs. As already mentioned, the light can come from above and below the discs. but may additionally or alternatively come 'from positions at the sides of the housing. The end to be achieved is that of producing averitable -iiood of varying colored light by retiection of that light from the -faces of the discs, which ood of light fuses into and out of various color combinations to. produce an intriguing fantasy -of color. While the lights, such as 9 and 10, are on and the reiiector discs are rotating, the flood of color is Yprojected with sufficient difference in application that though the in- -f Y tense colored light from behind will shine right through pulleysr28 and 29 anda belt 30. f The pulleys-are, of// course, secured it, light directed solely on the outer face of the mirror will make the display stand out. Hence at/the/ desired moment, by means ofthe switch 39,V light fro/m the sources 9 and 10 is cut oft and simultaneouslylight from sources i2 and i3, at the outer side of the half silvered mirror, is turned on. This latter light will impinge Vupon and be reflected .from/the mirrored surface and advertising display carried by the member '11. The displayy will stand out sharply, particularly so since the ood of colored light will be suddenly extinguished so one will no longer be able to see through themember 11. When the advertisement has been on display lon enough to be perceived by the onlookers which, as modern advertising techniques show, does not need' to be prolonged to have its etect felt, the procedure is reversed. The lights 12 and 13 are extinguished and, simultaneously, the lights 9 and 10 are turned on again. Preferably all of this is done automatically as part of a timed cycle, either forming part of, or in addition to, the timed cycle for lvarying the speed of the discs, if any, as hereintofore pointed out. There is no necessity for stopping the rotation of the discs during the light change from color to advertisement and back again, for the discs cannot be seen in any event. Furthermore it is preferable to continue their rotation, since the consumption of electric power and wear Vand tear on the mechanism is decidedly less than would be involved in the starting and stopping of the rotation on each change. A somewhat modied drive arrangement is illustrated in the form of FIGS. 3 and 4. Here a motor 27a is mounted on a bracket 4G' against the back wall 6 of the housing in such a manner thatthe motor shaft 23a is, at one and the same time, the shaft on which the centre disc 18 is mounted. This fmerely'eliminate's the belt drive arrangement of the previous form, with the gear drive between the gears 31, 32, 33 and 34, being the same as in the previous form. Also the discs are the same and are positioned in the same manner so that the description of them, given in connection with/the form of FIGS. l and 2, is equallyapplicable. v ,Iig/this/form, since the motor is strongly supported fnd assists on c ments per d1sc 1s desired to produce the -full effects. A5450 arrymg the Weight of the mechanism single and smaller bearings, for the various shafts as seen at 41 and 42, are possible. In all other respects the construction and operation of this form is the same as .that of FIGS. l and 2, so bears the same reference characters. A somewhat different type of disc and drive for the same is shown in FIGS. 5 and 6. Here each disc is made double, with a spacer and driving member inbetween. Accordingly the disc assembly `indicated at 45 has disc faces 46 and 47 with a separator member 48 of smallerV diameter between them. This separator member is peripherally bordered by a driving rim 49. The disc assembly 45 1s mounted on a shaft 50 and is heldtogether by means such as the nuts 51 and' 52 secured on the shaft. The -disc assembly 45 is characteristic of the three Aoutside discs while the centre disc assembly, generally Vindicated at 55, is somewhat different. The latter again serves as the drive member for/the set of discs, itself be-i ing suitably Ydriven in one of the manners previously shown, or in other suitable manner. The disc assembly 55 again has discpelements 56 and 57 spaced apart, not abscess only by spacer members 58 and 59, but, also, by the centre drive disc 60. The drive ydisc 60, which has its periphery supplied with suitable friction driving rim 61, is formed to inter-tit between the disc elements 46 and 47 of the other three discs and to engage their driving rim 49 in order to drive the same. The disc assembly 55 is suitably assembled and secured on the shaft 62 by means of the securing members shown. In the disc construction of FIGS. 5 and 6, assuming the provision of unobtrusive supports for the various shafts for the discs, the assembly of discs could be made visible from both sides simultaneously. In other respects the coloring of the discs, the operation, and the illumination of them would be the Sme as described for the previous forms, so need not be repeated here. In FIGS. 7, 8 and 9 various forms of hdf silvered mirror or screen arrangements for the element 11 are illustrated. As shown in FIG. 7 this element, no matter how constructed, besides being one where visibility therethrough depends on the relative illumination on the opposite sides thereof, carries advertising indicia. This indicia is only visible when light behind the element is cut olf and intense light is directed against the front surface thereof. This indicia can be made to stmd out in various ways. One of these is to apply the advertising with a different color or form of material from that forming the mirrored surface. Thus, in FIG. 8, a glass plate 65 is shown as having its inner surface 66 equipped with advertising indicia, or marking 67, along with the normally halfsilvering material 68. In the FIG. 9 showing laminated material, having two sheets 69 and 70, which may both be of plastic or one of plastic and the other of glass, are secured together with the half silvered and advertising indicia being incorporated in the layer 71 joining them. Though no specic provision has been shown for the incorporation of musical accompaniment to the color, this, of course, can be achieved by employing one of a variety of the types of recording and reproducing systems commonly available. The operation of such system can be keyed to the operation of the discs and lights, through one unitary timing mechanism or by separate timing mechanisms as desired. Whether' sound be added or not it has been found that this arrangement of rotating discs with intense light projected against them and, in turn, reflected out from them, produces an almost compelling urge to draw closer and see what is causing it. This establishes a highly effective medium for putting an advertising, or some other message, across to the viewers. In the absence of the advertising aspect, the display has such a pleasantly attractive appeal to it that it can be used alone as mere entertainment and is admirably suited for lling in such situations as where crowds are pouring into a theatre or other amusement place as a lead for the program to be put on. n Having described my invention what I claim as new and desire to secure by Letters Patent is: l.
