In the light spot display embodiment of the invention one of the members is rotatable about an axis thereof and designed to effect a passage of light to the display surface of the third member representative of die spots. Indexing means thereof will permit the showing of from one to six arrays of light spots. Another of the members is designed to effect light attenuating or filtering functions. This member is also rotatable about an axis thereof and indexing means associated therewith will permit an array of light spots to be displayed in any one of several different colors, such as white, red, green or yellow.

An object of the invention is to effect displays of a predetermined number of different patterns comprised of light spots and multiply the usefulness of the patterns available by the number of different colors in which the patterns can be displayed. These and other features and objects will best be understood from the following de scription when read in connection with the drawings hereof.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 includes a showing of an assembly of the various parts of the invention;

FIG. 2 is another view of the pattern and color control members;

FIG. 3 shows other details of the light filter member;

FIG. 4 is a surface view of the' display member included in the assembly of FIG. 1;

FIG. 5 shows a variation from the display means of FIG. 4;

FIG. 6 shows a modification of the display means of FIG. 5;

FIG. 7 shows a further variation of the display means.

DETAILED DESCRIPTION The assembly of the various parts of FIG. 1 includes a light source 10, and first, second and third light passage control members, l1, l2 and 13, respectively. The first member 11 is supported rotatably about an axis 21 thereof. The second member 12 is supported rotatably about an axis 31 thereof. And the first and second members have light passage control window areas therein selectively positionable between the light source It) and a fixed position light passage control window area of the third member 13. There is, therefore, a line 15 along and about which the selectively positioned window areas of the first and second members, the source of light and the window area of the third member 13 are established.

The additional view of the second member 12 in FIG. 2 shows window means therein each designed to form light spots in pattern formations representing, respectively, die spots one. two, three, four, five and six, each angularly spaced one with respect to the other 60, and a radial point about which each pattern is positioned is the same for each pattern. Upon rotation of the second member 12 by. for example. a momentary energization of electrical motor means 19 indexing means, such as magnets 1 being supported by member l2 and a reference magnet to fixedly supported in relation thereto as shown in FIG. ll, will influence the stoppage of the member 12 and thereupon permit different ones of the pattern formations to assume a reference position along line 15. In FIG. 2 the array of six light spots is shown in this position.

The color control member Jill is shown to have, for example. means for deriving four different colors from the light source l0, such as white, red, green or yellow. The

light filtering materials

22, 23, M and 25, as indicated in FIG. 3, can be supported on a light transparent base material 26, each occupying a fourth of the base 26 surface. Upon rotation of the first member ll by. for example. a momentary energization of electrical motor means 18 indexing means. such as magnets 34 being supported by the member El and a reference magnet 36 fixedly supported in relation thereto as shown in FIG. II, will influence the stoppage of the member Ill and thereupon permit different ones of the four light filters to assume a reference position along line 15.

The additional view of the third member H3 in FIG. 4 shows the window means dill therein to be comprised of nine holes therethrough. A reference point 150 about which this array of holes is positioned in the member l3 coincides with a similar pointalong the line 15 in the FIG. 1 assembly. From one to six of the nine holes will receive light from the source ll), depending upon the indexing of the second member 12 in relation to the line R5. The color or hue of the light from the source 10 will depend upon the indexing of the first member ill in relation to the line l5.

FlG. 5 shows a variation of the display means of FlG. to the extent of increasing the length dimension of the nine-hole window means We, The nine holes may, of course, be filled with a light guide material, such as plastic. But in view of their length to diameter dimensions, and when made of aluminum for example, the light reflecting walls thereof perform very well. FIG. 6 shows the display means 4t) wherein each hole is capped with a plastic lens.

In FIG. '7 the third member E3 of the FIG. 1 assembly is shown to include an opaque support material having a single opening 46 therein. A reference point 15a, and center point. of the hole 5%., coincides with a similar point along the line E5 in the EEG. l assembly. The opening 46, and preferably the entire surface 417 as well, is covered with a layer of a translucent material whereby a projection of light spots being derived from the light source I through the window means of the first and second members, Ill and l2, will be displayed on the surface $9 of the translucent material 48.

Various means can be used to effect a rotation of the control members Ill and i2, and electrical motor means 13 and 1%, respectively, are illustrated in FIG. 1 as being one such means. it will of course be understood by those sltilled in the arts that the first and second members, and l2, can be rotatably and concentrically supported about a common axle means. Although the second light passage control member B2 is illustrated as having but s arrays of window means from which patterns are ff/til'l-Ed a display surface, the inventi of co rse. r be made more useful by designing n but s r arrays of window I illustrated round ember l2; may

such openings or light transparent areas are given square or oblong shapes, for example.

It should understood by those skilled in the arts pertaining to the construction and application possibilities of the invention set forth herein that the embodiments included herein illustrate in a very limited sense the usefulness of the invention and that the invention includes such other modificatons and equivalents as may be seen by those skilled in the arts, but still being within the scope of the appended claims.
