This'invention relates to yimprovementsin advertising and similar display apparatus. The presentapplication is a substitute for an application filed by Ime June 7, 1922,

Serial No. 566,576. 'Y

The Value of any sign or display device depends primarily on its ability to attract and hold the attention of the observer and in this connection there are three factors 1o which are of prime importance, namely, the effects of motion, color, and mystification. lEach of these factors has its own value when present in a sign or display device or apparatus and where twoor more of thefactors are present Lthe ability of the sign to attract and hold attention is greatly `en hanced. Usually, however, signs or other display devices or apparatuses which vembody two or all three of the factors enumerated are expensive to install and maintain in operation. l Therefore, it is the primary object of the present invention to provide a sign or display apparatus in the operation of 'which the effects of motion,

color, and mystification will all be present and in which sign or the like the structure will beso simple as to adapt it for general advertising and display purposes.

More specifically, the invention has as 3 its object to provide a sign in the operation of which there will be presented to the ob-v server lthe effect or sensation of an ever changing array of colors, each color'originating at a central point and gradually eX- panding and blending, in a more or less annular form, with colors previously similarly originated, this ei'ect being produced through the rapid rotation of certain component parts of the apparatus and the senduced at the same time' By an arrangement of the component elements of the rotating color devices, there is also produced the effeet of a sign display surface or the like being gradually brought to clear view from a condition of indistinctness and then being sation of motionI being in this manner promay be automatically successively broughtv to view at'various Vperiods in the operation of the apparatus.'

Another object of the inventionis to provide a sign or display apparatus which may be installed in store windows or within interiors and in lar eembodments may be used in theoutdoor display of advertising matter. Likewise theinvention contemplates the provision ofI a display apparatus which may be employed as an attractive front for carnivals, shows, amusement parks, etc. Also the invention contemplates an apparatus in which the various effects produced maybe displayed by projection onto a screen as, for example, a motion picture screen or a screen stretched in a shop window.

1n another embodiment of the invention, means is provided for displaying a sample or an actual specimen ofthe article advertised, the said sample orspecimen being in an undisclosed manner brought to full view of the observer and then retracted and for a time concealed from view. In a further.

embodiment of the invention, means is provided for suddenly displaying to view the matter to be advertised' and subsequently permitting the matter to` fade from view. In the accompanying drawings: Figure 1 is a front elevation of one form of signy embodying the invention;

'llhe embodiment of the apparatus illustrated in Figs. 1 to 4 inclusive comprises a casing indicated in general by the numeral 1 and supported upon a suitable base 2 or in any other manner found expedient. 'llhis casing comprises a circumferential or cylindrical wall 3, a back wall 4, and a front 5 having a display opening 6 therein. rll`he apparatus further embodies a rotatable display member indicated in general by the numeral 7 and this member preferably comprises a circular front plate 8 having a concentrically located aperture 9, the purpose of which will" presently be explained. A spider 1() is arranged in rear of the face plate 8 and in spaced relation thereto and at the point of juncture of its arms is provided with a hub 11 which projects rearwardly from the plane of the spider and rotatably fits a stub shaft 12 which projects forwardly from the upper portion of a ixedly supported upright 13 located within the casing 1.

rllhe numeral 14 indicates an electric or other suitable type of motor froml which power is to be derived for operating the apparatus and upon the shaft 15 of this motor there is xed a pulley 16 about which is trained a belt 17, the belt passing alsoI about a pulley 18 either xed upon or constituting aninteg'ral art of the hub 11 of the display member 7. In this manner rotary motion is imparted, preferably at a high rate of speed to the said member 7, and the member, while in rotation, may be viewed through the display opening 6, the `face of the plate 8 being presented toward this opening. If desired, variously arranged color areas may be provided upon the face of the said front 8 of the member 7, as, for example, concentrically or eccentrically arranged color areas 19, as shown in Fig. 1.

In combination with the display member 7, there is provided a color imparting medium or display member whichis indicated in general by the numeral 20 and this medium preferably comprises a flat circular disc .21, the face of which is divided into a number of sector-like areas 22 which may be given different colors. For example, the

areas or fields 22 may be colored red, blue, yellow, and green, and one if desired may be colored white, the disc 2l being provided, preferably in this' latter eld, with a display opening 23 which isof substantially the same diameteras the opening 9 and in certain phases of operation of the apparatus to be presently described is adapted to be brought into substantiall registrationv with Maasai said opening 9. The disc 21 is mounted axially upon a stub shaft 24 projecting from the forward face of the front 8 of the display member 7 and the disc 21 is provided with a hub 25 4having a sprocket gear 26 fixed thereon. A. sprocket chain 27 is trained about the gear 26 and about a similar gear`28 fixed upon the forward end of `a shaft 29 journaled at the periphery of ,the member 7. A worm gear 30 is fixed upon the rear end of the shaft 29, and a worm 31 at the outer end of a shaft 32 meshes with the said worm gear. rlhe shaft 32 is rotatably journaled in suitable bearings 33'upon one of the arms of the spider 10 and at its inner end hasV ixed upon it a worm gear 34 which is in mesh witha worm -35 upon the exterior of a collar 36 which is loosely fitted onto the hub 11 of the member 7 in frontvof the pulley 18. rllhe collar 36 is notched-at one point in its circumference in its rear end, as at 37, and a resilient locking nger or pawl 38 is fixed at one end, as at 39, upon the upper end of the upright 13 and is provided with a toothed end 40 which engages in the notch 37 and in this manner serves to hold the collar 36 against rotation with relation to the hub 11 and at the same time permitting of free rotation of this hub upon the stub shaft 12 and Within the collar. At this point it will be evident that as the member 7 is rapidly rotated through rotation -of its hub 11, the worm gear 34 will be carried around the worm 35 and in its travel will be given slow rotative movement which is imparted to the shaft 82. In this manner relatively slow'rotative movement is imparted by the worm 31 and worm gear 30 to the shaft 29 and the motion is transmitted from this shaft to the hub of the medium 2O thus rotating the disc 21 comprising this medium. As the member 7 rapidly rotates, the member 20 is carried around with the same and the colors of the sector-shaped areas or fields 22 will be caused to blend with one another and with such color areas or fields 19 vas may be present upon the face of the front 8 of the said member 7. rlhe speed vo f rotationl of the member 7 is in practice so rapid that the character of the member 20 is not perceptible to the eye and the presence of this member is noticeable only by reason of the blending of its several color fields. When one of the color fields, as, for example, the red ield, is in position oppositethe central portion of the face plate 8, the opening 9 will, of course, be closed or covered and, in the rapid rotat-ion of the assemblage,1 `a central red area or zone will be presented to view, and surrounding this area will be presented a number of concentric zones of various colors produced through blending of t-he various color areas or fields 22 and also the areas ing 9.

or fields 19. As the apparatus continues to operate, the disc 21 will be slowly rotated and the next color field 22, in order, will' tion of the disc 21, the initially relatively y small spot of red at the center of the display surface in general will be seen to pand in all directions, and likewise t e blended colo'r zones surrounding thisr ce tral zone will be seen to expand and eventui ally disappear from v iew. At the vsame time the colors will be continuously blended' in a manner to produce practically every conceivable color and tints thereof, and ,the

composite color field thus produced will, in fact, be continuously changing its aspect,

f resentino' a most leasin a "earance to the eye and holding the attention of the observer. As previously stated, the speed of rotation of the disc 21, is relatively low so that the blending of the color areas or fields will be more or less graduai and yet the sensation experienced will be that of extreme rapid motion. Finally in the operation of the apparatus, the color area in which the opening 2 3 is located will be brought gradually to position in front of the opening 9. Means is provided in back of the opening 9 and face plate 8 in which this opening is' formed, bearing advertising or display areas, and as the opening 23 gradually eclipses the opening 9, the matter displayed in rear of the opening 9 will be at first 'dimly and indistinctly brought to view and will then be graduallyn more clearly defined as the opening 23 is brought more nearly into registration or alinement with the opening 9. Finally, the openings will be thus positioned and the advertising or display matter will be exposed clearly to view through these openings and the display opening 6. Continued operation of the apparatus will result in the opening 23 again eclipsing the opening 9 and in a gradual manner so as to produce the effect of a gradual fading from View of the advertising or display matter previously dis-y played through said

openings

9 and 23.

The operation is then automatically repeated in the manner. just described.

The medium employed for displa ing the signs or other displa matter and a j ve referred tois indicate in general by the numerall 41 andv in this form of the invention preferably Acomprises a circular disc 42 which is rotatably mounted upon a. -stub shaft -43 projecting from a depending arm 44 secured preferably by `eoacting jamb. or clamping' nuts 45 upon 'the forward end of the stub shaft 12, the arm 44 being in this manner rigidly supported. The discv 42 is located within the bounds of the member 7 and in rear ofthe face plate 8 thereof and itis provided upon its forwardly presented 'face 'with a`number of advertising or display areas 46 which may be of vdifferent characters and which'are to be successively displayed. The fields or` areas 46 are so arranged in an annular series about the center of the disc 42 that when thedisc ies rotated through predetermined angular distances the fields or'areas will be successively brought to position op- A ,y

posite the opening 9 and will, of course, be presented to view when the opening 23 is.

tions prevlously explained. In order that the disc 42 may be held in each of the positions to which' vit isA automatically rotated by means to be resently pointed out, a cross piece 47 is 1 xed transversely ofthe supporting armf44 and an upwardly bowed leaf spring 48-is fixed at one end, as at 49, upon the upper side of the cross piece and' has its Y other end 50 resting freely in engagement with the upper side of the cross piece. A number of studs 51 are arranged in an annular series about the axis of the disc 42 and project from the rear face of said disc and in each position -of rotative adjustment of the disc, two of these pins or studs will simultaneously engage the oppositesides of the bow or bulge in the spring 48. When rotative movement is imparted to the disc 42 to shift it from one position of adjustment to another, one of the studs or pins 51 will ride over the bow or bulge of the spring and finally when the disc comes to rest it, together with the next stud or pin in the series,

will be positioned in engagement with the' spring and the disc will thus be held in its new position of adjustment. In order to automaticall effect rotative adjustment of the disc 42 intermittently during operation of the apparatus, a tappet finger 52 'is fixed upon the forward end of a shaft 53 rotatably mounted through the bore of the hollow stubv shaft 12,'and upon rotary motion being imparted to this ,shaft the tappet finger 52 will at suitable intervals sweep into engagement with the successive pins 51, thus intermittently rotating the disc 42. In ordert to impart rotary motion to the shaft 53, a sprocket gear -54 is fixed upon the rear Vend of the shaft, and a sprocket chain 55 is trained -about this gearand about a gear 56 fixed uponi'the rear end of a shaft V57 journaled through the upright 13. A worm gear 58 is fixed upon the forward end of the shaft 57 and meshes with a worm 59 provided upon the lower end of a shaft 60 journaled in suitable bearings 61 vupon the said upright 13.- A worm gear (i2-is fixed upon the upper end of theshaft v60 and meshes with a worm 63.which is keyed upon the rear end 'of the hub 11. Thus as the member 7 is rotated,

corresponding motion will be imparted to the opposite the'said opening 9 under the condilis front of the casing 1.

worm 68, and a slow rotative movement will be imparted to the shafts 60 and 57 and finally to the shaft 53.

ln order that the display surface of the sign may be suitably illuminated, alight 64e may be provided at the upper side of the Uf course, in the daytiinethe displa surface will be sufficiently illuminated y natural light, and the electric light 64 need, therefore, be only employed at night.

Fig. 5 of the drawings illustrates a simplified embodiment of the invention in which an upright 65 is iixedly mounted in any suitable manner and is provided near its upper end with a forwardly projecting fixed shaft 66. Rotatably mounted upon this shaft is the hub 67 of a display medium, indicated in general by the numerall 68, and corresponding to the medium 7. Ilihe medium 68 comprises a face plate 69 and a spider l70, as in the previously described structure,

and the face plate is provided centrally with an opening 71 corresponding to the opening 9. A shaft 72 is rotatably Journaled in the member 68 and has }"fixed upon its forward I end a color imparting medium 78 comprising a disc 74 which may be provided with variouscolor fields or areas corresponding lto the areas 22 of the disc 21 previously described. Like the disc 21 this disc 74 is also provided with an opening 75 which is adapted to be brought opposite or substantially in registration with the opening 71. A worm `gear 76 is fixed upon the rear end of the shaft 72, and a Worm 77 is provided at y .the outer end of a shaft 78 and meshes with this gear. The shaft 78 is mounted in suitable bearings 79 upon one arm of the spider 70, and a worm gear 80 is fixed upon the inner end of the shaft 78 and meshes with a Worm 81 which is loosely fitted on to the hub 67 and is held stationary in the same manner as the worm 85. It will now be evident that as rotary motion isimparted to the member 68 at a high rateof speed, corresponding motion at a low rate of speed is imparted to the member 7 3 4and substantially the same eHects will be produced as in the previously described form.

Rotary motion is imparted 4to the hub 67 through the medium of a belt 82 which is trained about pulleys 83 and. 84 mounted, respectively, upon the hub 67 and the shaft 85 of an electric or other suitable type -of motor 86. In this form of the invention,

vthe display or sign medium is indicated in suddenly presented to the view of the observer and subsequently retracted and then concealed for a period of time after which it is again presented to View, and in this figure the numeral 89 indicates a standard corresponding to the standard or upright 13 and provided with a forwardly projecting tubular stub shaft 90 upon which is rotatably mounted the hub 91 of the rotatable display member 92 which corresponds to the niember 7 heretofore described. Vlhe hub 91 supports a worm 98 corresponding to the worm 35 and operating in the identical manner and serving the same purpose as the previously described worm. Also there is .fixed upon the hub 91 a worm 94 corresponding in function to the Worm 63 and transmitting motion at a relatively low rate of speed to a sprocket gear 95 corresponding to the gear 54 and fixed upon a sleeve shaft 96 rotatablyjournaled in the tubular stub shaft 90. rlFhe numeral 97 indicates a bracket arm which is fixed upon the forward end of the stub shaft` 90 and rotatably supports a sign displaying med-iurnl 98 corresponding to the medium 41 previously described and comprising a disc 99 bearing a substantially annular series of sign ordisplay surfaces corresponding to the surfaces 46. However, this series is interrupted at one point by an opening 100 formed in the said disc 99, and it will be understood from what has been said with regard to the 0peration of the form of the invention shown in Figs. 1 to 4 that at a period in the operationof the apparatus the opening 100 will be brought opposite the opening in the face plate of the member 92 and the opening in the color imparting disc which is not shown in this view but correspondsto the disc 20. An arm 101 is fixed upon the forward end of the sleeve shaft 96 and hasa forwardly directed finger 102 adapted to successively engage pins 103 projecting from the rear face of the disc 99 and corresponding to the pins 51. Thus in substantially all respects this structure, as `so far described, is -substantially identical with the corresponding structure shown in Figs. 1 to 4, inclusive. However, in this modified form a supporting rod 104: is slidabl mounted through the sleeve shaft 96 an located as to be opposite the opening 100 when the opening is in the position above described. rllhis end of the rod 104 supports the sample or specimen of the article advertised or some object pertainin as, for example, a powder puff, indicated by the numeral 105, where such an. article or the face powder to be applied thereby is the 'subject of the advertising matter. The

rod 104 projects at its rear end beyond the" rear end of the sleeve shaft 96 and is urged in a forward direction, yieldably, by a spring has its forward end so thereto with an angularly directed linger 107 having a nose 108 engagingthe working surface yopening 100 and into plain view of the yobserven t Fig. 7 of the drawingsillu'strates a modilication of the display surface in which the advertising matter to be displayed by the member 4l heretofore described is adapted to be brought suddenly intoview when the

openings

9 and 23 arein position opposite each other. In this structure, the `display medium, corresponding to the medium 7, is. indicated in general by the numeral 111, and the color,imparting medium, correspondlng to the medium 20,- is indicated in' general byl the numeral 112. This latter medium, as

in the former instance, comprises a disc 113 provided with a selected arrangement of color fields or areas and formed at one point with an opening 114 corresponding to the opening .23. Stop pins 115 and' 116 are arranged upon the face `of the disc 113, and a shutter 117 is ivotally mounted at its end, as at 118, pre erably concentrically ofthe said disc. In one position of its pivotal movement, the shutter is designed to rest at one lateral edge against the stop pin 115 and in. such position will cover the opening 114. In the operation of the apparatus, the shutter 117 will be maintained in this position, through centrifugal force, vuntil the disc l113 has been rotated to substantially the position where the opening 114 will be directly opposite the opening in the member t 111, corresponding to they opening 9, at which time the parts will be in such position thatl the centrifugal force will act to swing the shutter blade 117 into engagement with the stop pin 116-and at this time the opening 114 will be uncovered. This movement of the shutter blade is practically instantaneous and, therefore, the advertising matter to be displayed Will be brought suddenly into view-with a more or less startling effect.

In the previously described forms of the invention, purely mechanical means are employed for imparting rotary motion to the color imparting medium but in Figs. 8 and 9 there is. illustrated' a means whereby this motion may be obtained without the use of gearing or other `positive driving means. In

.this modification, the ldisplay medium which l corresponds to the .medium 7 is indicatedin general by' the numeral 119 andthe color lmpartlng medlum` is indicated in general 'Fan blades 125 are fixed upon the sha bythe numeral 120 and comprises, as before, a disc rovided with a suitable selection of color elds and with an opening121, corresponding to the opening 23, and designed to be brought opposite an opening 122 in the display medium 119. The disc comprising the medium 120 is fixed upon the forward a end 'of' a shaft 123 rotatably journaled through the face plate of the medium 119 andthe substantially cylindrical casin 124.

gt 123 within the casing 124, and the casingis provided in that side of its circumferential wall which is resented inthe direction of-rotation of tiie member 119 `with an air inlet opening 126, thearea of which may be regulated by means of a circumferentially adjustable slide 127 4arranged and supported vupon the outer side of the said circumferential wall of the casing. One vor more vent or air outlet perforations 128'may be formed in an approximately opposite portion of the circumerential wallfor 'the escape of air from the casing. In'this form of the invention, as the member 119 israpidly rotated, an inrushing 'current of air through the opening 126 will act upon the fan blades 125,

thus imparting rotary motion tothe disc Under some conditions, it may be found desirable instead of displaying the surface of the apparatus to direct view of an observer toproject an image of the surface upon a screen or the like, /and under these conditions an apparatus, such as illustrated in general in Fig. 10 of the drawings, may

lbe employed.- This apparatus comprises a casing 129 housing, for example, the apparatus disclosed in' Figs. 1 to 4 inclusive, or any other of the described modifications thereof, and this casing is provided with a projecting front portion`130 terminating in a lens lmount 131 supporting a projecting 'lens 132, one or more electric light bulbs,
