E. B. MONHEIM. NOW BY MARRIAGE E. B. WALKER ILLUMINATING APPARATUS FOR DISPLAY PURPOSES Filed Dec. 16, 1929 INVENTOR g; B. Moafielh;

Patented Aug. 9, 1932 UNITED STATES PATENT orrice ELSIE B. MONHEIM, NOW BY MARRIAGE ELSA. B. WALKER, OF SEATTLE, WASHINGTON Application filed. December 16, 1929. Serial lid-414,375.

This invention relates to illusion apparatus, and more particularly, to devices of this character designed for advertising or decorative purposes, such as sign boards, window '5' displays, and such, in a manner whereby an interesting and attractive lighting effect is produced to the display.

The object, generally speaking, is the provision, in apparatus of this character, of means whereby the effect of motion is given to light rays emigrating from a hidden source. 7

A further object resides in the manner of producing a difi'usion, through a plurality of reflecting mirrors disposed at varying angles of pitch, a most efiicient illumination to the display surface. Further and more specific objects and advantages, will, it is believed, become apparent.

The invention consists in the novel construction, arrangement and combination of devices as will be hereinafter described and claimed.

In the drawing,

Figure 1 is a front elevation of a sign board embodying structure peculiar to the invention. Fig. 2 is a vertical transverse section to the same. Fig. 3 is a diagrammatic view indicating, in a substantial horizontal section through apparatus as disclosed in Figs. 1 and 2, the effective direction to emigrating light rays. Fig .4: is an enlarged detail longitudinal vertical section of a preferred embodiment of the present conception of mechanism for imparting motion to the light rays, parts being shown in side elevation.

Reference being had to the drawing, and more particularly to Figs. 1-3, I provide, mounted as shown, substantially centrically above a sign board 5, a hood 7 housing, to the rear of the sign board 9, a source of light, such as the filament of an electric lamp 8, peculiar structure therewith being hereinafter described in detail.

Said hood is preferably disposed to project to a relative distance beyond the face of the board providing on its inner face, a plurality of mirrors 11.

As indicated by a vertical section (Fig.

2) through the source of lightrays, said mirrors are desirably arranged in varying angles progressively increasing outwardly from a substantial horizontal to a right angular disposition.

As disclosed in- Fig. 3, I indicate, in horizontal section, similar progressive angular dispositions to the mirror reflectors, which in effect provide conjointly, a prismatic surface similar to the facets of a diamond.

Particular attention being had to Fig. 4, the sign frame provides a cabinet 12, within which cooperative spaced

standards

20, 21, are arranged to support a hollow arbor 13, said arbor acting as a journal bearing for a pair of rotative bushingsl, 15 sleeved one within the other, and respectively secured to rotative base plates 16, 17.

18 represents a socket provided by said arbor for the reception'of the aforedescribed globe 8, wiring 19 passing through the arbor bore. As indicated, I provide, secured to the rims 24:, 25, of said base plates, a pair of semi-globular lenses 22, 23, the surface of which may be frosted, variably colored, or as shown, providing a plurality of markings, such as l8, arranged to intercept the emigrating light rays.

I contemplate actuating said globes in oppositional directions of travel, to such end providing, secured to respective bushings, driven spurgears 26 and 27.

28, 29 and 30 represent reduction gearing from a power source such as a motor M. An idler 31' is interposed for meshing engage 'Inent between gears 26 and 30.

The" invention involves a multiplicity of light rays, conjugating successively over a display surface. Illusions of drifting snow, heat waves, sand drifts, and such, are achieved, dependent upon the use of selective globularefl'ects; V

The illustrative description of the now preferred embodiment of the inventionis believed clear from the foregoing. However, I do not wish to be taken as confining myself specifically thereto, except as limited by the scope of the claims hereto annexed' What I claim, is,

. 1. Advertising apparatus comprising, in

combination with a display, a hood projecting beyond the face of the display, said hood providing a reflecting inner surface arranged in prismatic facets, angularly disposed, one to I the other, about a substantial 180 arc, means to introduce light rays to said reflecting inner surface, and means to impart an effect, of motion to said light rays across the face of the display.

2. In apparatus as described in claim 1,

wherein certain of said light rays travel in 1 oppositional directions. c 3. In illuminating apparatus for a display, the combination with a hood arranged to house a source of light and havingthe inner surface formed to provide a plurality of angularly disposed reflecting facets, of-means' to impart an efl'ect ofoppositional directive I travel across the face ofthedisplay to light rays from said source reflected'by said facets.

4. In illuminating apparatus for display purposes, the combination with-a hood arranged to house a source of light and having the inner surface formed to provide a substantially arcuately disposed reflecting surface, of means to impart an eflect of oppositional directive travel across the faceof the display to the light rays from said source in troduced to said surface;

5. Illuminating apparatusfor display purposes including a hood arranged to house a source of light and having the'inner surface formed to provide a plurality of angularly disposed reflecting facets from Which the light rays from said source are reflected, and means to impart an effect of motion to said light rays across the face of the display.

i 6. Illuminating apparatus for display purposes-comprising, in combination with the 40 display, a source of light for'illuminating said display, a hood arranged to house' said 7 sourceof light,'said hood providing an inner surface adapted to impart variable angles of reflection to light rays from said source in reflecting the same therefrom to the display,

and means for imparting an effect of motion to such light rays from the source-reflected over thedi'splay.

7. Illuminating apparatusfor display pur- V .poses comprising, in combination with the display, a source of light for illuminating said display, a hood arranged to house said source of light, said hood providing an inner surface adapted to impart variable angles of reflection to light rays from said source-in reflecting the same therefrom to the display, and means for imparting an effect of oppositional directive travel'to such light rays from the source reflected over the display.

Signed at Seattle, Washington, this 6th day of December, 1929.
