provision of a display device which shall consist of or include a picture having fixed parts and moving parts, the moving parts givbe reduced. Another object is mg the appearance of actual motion during the actuation ot the device. One object is the provision of a display device of the type described, in which the number of parts shall the provision of such a device in which the appearance of motion shall be improved in its realism. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein Figure 1 illustrates parts broken away;

Figure .2 is a section on the line 2-2 of Figure 1;

Figure 3 is a detail of the type of shutter shown in Figure 1;

Figure 4 is a detail;

Figures 5, 6 and 7 illustrate variant forms of incandescent globe or bulb which may be employed with my device, Figure 5 illustrata side elevation with mg one which is adaptable to the design il- B lustrated in the parts of Figures 1 and 3;

Figure 8 illustrates a form of exterior shade with an ornamental desi thereon;

Figure 9 illustrates a mov' g shutter apprgpriate for use with the shade of Figure 8; an

Figure 10 illustrates a form of bulb ap-, propriate for use with the members shown in Figures 8 and 9;

ike parts are indicated by like symbols throughout the specification and drawings.

Referring to the drawings and considering first the form of Figures 1 to 5, A generally indicates any. suitable base upon which may be mounted a translucent. shade A which may be provided with any suitable illustrative designs and may for example include water portions A land portions A and the moon A. member A is fixed. It may support any suitable cover or top member A Referring for example to Figures 1 and 5,

It will be understood that the C 1931. Serial No. 543,331.

B generally indicates an incandescent bulb having the screwthreaded portion B adapted to lit into the usual electric light socket B l3 indicates the usual wiring connection adaptable for insertion by means of the plug into any suitable electric power outlet. The lower portion of the bulb B is irregularly formed or grooved as at B in order to break up the light which is delivered to the portion A of the outer screen A. It will be noted that the interior of the portion A ,'in line with the irregularly formed portion B of the globe B is also irregularly formed as at B. This formation of the globe and of the inner surface of the screen member A g in cooperation with the exterior water design on the screen A tends to give an efi'ect indicating the reflection of light upon water. The upper portion of the bulb may be formed with a design generally corresponding to the design upon the screen A For example in alignment with the land portions A of the screen I may illustrate more or less opaque port-ions B of the bulb B. In line with the moon A is the moon B in the shape of a spot of clear glass through which light freely passes, the rest of the surface of the bulb being less translucent, in varying degree. Note also that the degree of translucence in the portion. B of the bulb B may be varied. For example the bottoms of the individual grooves or troughs may be either more or less translucent than the tops, thereby obtaining an uneven distribution of light such as is characteristic of moonlight upon water. Referring again to Figure 1, C indicates a pivot support terminating in a point C adapted to penetrate an aperture G in the center of the top frame C from which depends the light pervious shutter structure C. This structure is shown in the form of a cylinder having a lower portion C provided with diagonal lines or bands or strips C of varying translucence. The upper portion of the member C may be provided with a design including clouds C on a sky background When the parts are in the position in which they are shown in Figure 1 and the electric light is lighted, the heat of the light causes the air to flow upwardly through the base A and within the chutter G into contact. with the fan members C whereby the upward flow of heated air causes a rotation of the shutter member (3*. The heated air may flow upwardly through the shutter members D D provided with opposed apertures D Since the members D, D as shown in Figure 4, are relatively rotatable, the degree of overlap of the apertures may be controlled and thereby the speed of upward circulation of the-heated air thus providing controlling means for the speed of rotation of the shutter C: It will be realized that when the shutter C rotates it passes between the bulb B and the outer member A The shutter may be entirely translucent, but of varying degrees of translucence, the effect of its rotation will be to cause the appearance of clouds floating across the sky portion of the design shown in the member A The inclined strips C passing between the relief portions B and B of globe and shutter, cooperate in giving a very lifelike imitation of the reflection of moonlight upon rippling or moving water. The clouds will give appearance of occasionally passing over and partially obscuring the moon.

This particular design is merely illustrative and I do not-wish to be limited to any specific design. For example I may employ the design shown in Figures 8, 9 and 10 in which the member A is formed with a lower water section E, a waterfall E the boiling whirlpool or agitated water E at the base of the waterfall and the cloud covered sky E above the fall, with mountains or rocks E at one side. In order to assist in obtaining the realistic water effect I undulate or otherwise relieve the inner surface of the.

member A as at E. In the place of the generally smooth bulb, of Figure 5 I may employ the bulb of Figure 10 which carries sub-' stantially the same design on it, either in color or in relief as is carried on the outer screen of Figure 8. This bulb may have the water undulations or reliefG, a portion G corresponding to the waterfall, the .portion Gr corresponding to the portionE of the screen, the cloud covered sky G and the rocks or mountains G". Preferably the design is helped out in relief, the undulating character of the water being clearly illustrated in Figure 10. However, the same effect rnay be obtained at least partially by merely varying the translucence and color of the various parts of the design.

I may employ with the screen and bulb of Figures 8 and 10 a shutter including the lower water portion I-I having inclined or spiral lines of varying color and translucence. A smaller band H is aligned with the disturbed water E or G at the base of;

the waterfall. The band H in the shutter is represented by rather sharply inclined bands of varying color or translucence, inclined in opposition to those of the water band as indicated at H. H is a band in alignment with the waterfall E and H is aband of sky flecked with clouds. In the operation of the device the rotation of the shutter between the bulb and the outer screen results in a very lively and realistic imitation of flowing water in the lower portion of the picture, a waterfall and a whirlpool or surge of water at the base of the waterfall, with clouds actually passing over the sky above.

The bulbs I and I of Figures 6 and 7 merely illustrate different types of bulb which may be employed to obtain difierent effects. For example the bulb of Figure 7 is useful in obtaining an effect of falling rain whereas the bulb of Figure 6 fits well into fire scenes.

It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

I find it desirable in providing a display device to give the illusion of moving parts in a picture, to employ a fixed screen, herein shown as a cylindrical outer screen, and a light source. I place between the screen and I the light source a moving shutter. Preferably I position within the moving shutter and about the light source a second fixed screen, which may be the glass or envelope of the light source itself. I prefer to form or mark the bulb to conform to and help in the illustration of the desired picture. This is illustrated in Figures 5, 6, 7 and 10. I may do this in relief or by varying translucence or by variation in color or by any desired combination thereof. I have illustrated as examples the employment of bulbs having undulating water portions, fire portions and the like.

I also find it desirable to form one or both faces of the outer screen in relief. I have herein illustrated the relief as applied only to the inner face. In general this is preferable as it permits a smooth, for example, cylindrical face, for the display of the picture. On the other hand I do not wish to be limited to the employment of relief on the inside only or to'the employment of relief at all.

Preferably I avoid the employment of opacity. For example my bulb may have no opacity whatsoever. This is to be pre 'ferred, since opacity merely cuts ofi and was es light and I an o tain my desired 25 fects of light and shade or of light and dark mainly by varying or contrasting translucence. The shutter C also is preferably free of opaque portions and while I do not wish to be limited specifically, except so far as I limit myself by my claims, to an arrangement in which opacity is not employed, I find that on the whole variation in translucence is to be preferred.

p I claim:

1. In a display device, a light source, a translucent exterior display member carrying a picture having portions representing fixed objects and other portions representing objects in motion, the various portions of said picture being of var ing translucence and color, a normally xed, translucent screen interposed between said light source and said display member, said screen being of varying translucence and being adapted to cause the projection upon the translucent display member of light varying in intensity in relation to the different parts of the picture, and a moving translucent screen, interposed between said fixed screen and said translucent display member, said moving screen including portions of varyingtranslucence and being adapted to cause, in response to its movement, an appearance of motion upon the translucent display member, said display member and fixed translucent screen including surfaces having portions in relief, in association with the picture.

2. In a display device, a circumferential translucent screen having a design on the exterior surface thereof, the interior surface being formed in relief in relation to said design, a light source within said circumferential screen and a moving light pervious screen interposed between said circumferential screen and said light source, said moving screen having associated therewith design portions relating to the design upon the circumferential screen.

3. In a display device, a translucent screen having a picture thereon and an incandescent bulb associated therewith, said bulb being provided with relief portions having relation to the picture on said screen. o
