Abstract

A lighted display providing a most interesting and unusual pattern of streaks of light intermittently pulsed inside an attractive housing. Light appears to travel in lines and in rotation and the effect is obtained from a light bulb mounted on one side of slots and the other side of which has transparent light conductor member such as ''''Lucite'''' or ''''Plexiglas'''' plastic moving across the slot. In one form the light conducting members are in different shapes and are mounted substantially vertically from a turntable which is motor driven on an enclosed base in which is a pair of slots and respective projection lamps so that as the bottom edge of each light conducting member passes across the respective slot it receives a pulse of light momentarily which is conducted through that member at least momentarily while it continues to rotate. For additional effect the turntable and light conducting members are contained within a plastic housing which has opaque sides, red tinted sides and blue tinted sides. In another form the light conducting members are carried by a revolving belt around a cylindrical member in which is mounted a projection lamp inside a second drum in which is a slot communicating with the edge of each light conducting member of which there are several radiating from the drum. In another form the light conducting members are mounted on a slotted belt which is rotated over a transparent drum in which is mounted a second drum in which is mounted the projection lamp and there is a slot in the drum through which the light is conducted.

Henry [57] ABSTRACT A lighted display providing a most interesting and un [4 1 June 12, 1973 such as Lucite or Plexiglas plastic moving across 1 the slot. In one form the light conducting members are in different shapes and are mounted substantially vertically from a turntable which is motor driven on an enclosed base in which is a pair of slots and respective projection lamps so that as the bottom edge of each light conducting member passes across the respective slot it receives a pulse of light momentarily which is conducted through that member at least momentarily while it continues to rotate. For additional effect the turntable and light conducting members are contained within a plastic housing which has opaque sides, red tinted sides and blue tinted sides. In another form the light conducting members are carried by a revolving belt around cylindrical member in which is mounted a projection lamp inside a second drum in which is a slot communicating with the edge of each light conducting member of which there are several radiating from the drum. In another form the light conducting members are mounted on a slotted belt which is rotated over a transparent drum in which is mounted a second drum in which is mounted the projection lamp and there is a slot in the drum through which the light is conducted.

2 Claims, 15 Drawing Figures LIGHTED DISPLAY BACKGROUND OF THE INVENTION DESCRIPTION OF THE PRIOR ART There are early animation devices such as the phenakistascope and zoetrope. Known prior art devices also include those which utilize illuminated members mostly project an image or colored light on a panel or a scene which changes mechanically from time to time. There is essentially and virtually no air of mysticism about such an arrangement since the operation and illumination is fairly obvious to most observers. In the field of fiber optics light is conducted through solid bodies to present unusual and unique patterns. Such arrangements are very interesting and command much attention but can be extremely costly and difficult to operate. The present device in a sense may simulate fiber optics but without using the materials and arrangement of fiber optics. Display devices should be interesting and unusual and command the utmost attention when there is an air of mysticism and lack of understanding. Known prior art devices are so well known in arrangement that they lack the novelty and unusual presentation.

SUMMARY OF THE INVENTION Moving, light conducting members such as plastic pieces receive a short burst of light in passing across a slotted opening and are moved and housed in such a manner as to present an air of mysticism with an appearance of moving light without the appearance of I moving mechanism. In one form a simple turntable with slotted openings and pieces of light conducting plastic housed in a plastic casing provide interesting and unusual patterns of light that escape immediate detection as to construction and operation. Unlike more complicated fiber optics and other illuminated devices there are no complex switches, limit switches or contact switches and there is no complex arrangement of sequential relay operation and other more expensive and less durable equipment.

FIG. 12 is a cross-sectional view taken along lines DESCRIPTION OF THE PREFERRED EMBODIMENT The embodiment shown in FIG. 1 is designated generally byreference numeral 10 and comprises an at? tractive outer casing or housing designated generally byreference numeral 14 which is constructed in box-like formation withopaque sides 16,transparent sides 18, andopaque top 20 and an open bottom 22 which fits about theupstanding rim 24 of a base designated generally byreference numeral 26 and which is box-like in formation withsides 28 and a bottom 30. Acover 32 mounted within thebase 26 has an opening 34 exposing a small fan blade 36 on a motor shaft of motor 38 which is attached to the bottom 30. A conventional phonograph turntable drive assembly designated generally byreference numeral 40 comprises anelectric motor 41 which drives apulley 42 having a rubber peripheral edge and which drives a dependingflange 44 on theturntable 46 which is supported for rotation on ashaft 48 attached to thecover 32.

Cover 32 includes raisedplatforms 50 in which are respective slots 52 and the slots 52 are diametrically opposed about theshaft 48 to be on opposite sides of theturntable 46.

Turntable 46 is constructed from lightweight metal, plastic or the like and has attached thereto inslots 54 therein a plurality oflight conducting members 56 made from thin plastic material such as Plexiglas or Lucite" and of irregular and odd shaped patterns as shown in FIG. 1.Light bulbs 62 are mounted beneath the respective slots 52 and are inserted in conventional electrical sockets 64 attached to base 30. Electricity is delivered to the base and through suitable wiring to each of the electrical components from a plug-inwire 66 that plugs into any conventional wall socket. Theinput lines 66 may be wired to a switch 70 providing on-off operation of theentire unit 10.

As seen in FIGS. 5 and 6, light through one of the slots 52 is conducted through theslot 54 and thelight conducting members 56 and since these members are in odd and irregular formation having voids and openings therein the light is conducted in an irregular and unusual pattern for each one of the light conducting members and with notches and grooves such as 72 therein the light is caused to burst from the side orface 74 as well as many other and varied patterns and effects of light. At the same time theturntable 46 is rotating so the light conducting member receives through the turntable speed of 78 rpm. This coupled with theopaque side 16 and thetranslucent sides 18, particularly in a subdued light or darkened room, produces a most unusual, mysterious and commanding pattern. The light appears to come from arcs of electrical energy as might be produced by high voltage between certain points or the effect obtained by some complex and expensive fiber optic devices which are controlled from sensitive relays and switching means. Actually as noted herein the effect in the operation is quite simple and the materials are relatively inexpensive. The plastic, for example, used in themembers 56 can be scrap pieces obtained from many different plants as waste material.

In the embodiment shown in FIG. 7, the same result is obtained and the principle is the same by means of a drum assembly designated generally byreference numeral 100 havingslots 102 therein in which are mounted radially extended plasticlight conducting members 104 which in this case are all regular and rectangular pieces of material suitable for carrying a message thereon.Drum assembly 100 includes theouter drum 106 to which thelight conducting members 104 are attached in theslots 102 and also includes aninner drum 110 mounted concentrically therewith with respect to alongitudinal support shaft 112 supported on a metal frame orbracket member 114 attached byscrews 116 to the outer edge ofdrum 106. Theinside drum 110 has alongitudinal slot 118 through the shell thereof and there is alight bulb 124 mounted inside theinside drum 110 in a conventionalelectrical fixture 126. The entire device may be mounted in a plastic housing (not shown) with suitable opaque sides and tops as desired.

In the operation of the device shown in FIG. 7, theinner drum 110 is stationary on the housing whereas the outer drum assembly withdrum 106 and thelight conducting members 104 is caused to turn by rotatingshaft 112 which is attached tobracket 114 whereas a support shaft 130 maintains theinner drum 110 in stationary position. The effect obtained is similar to that in the embodiment shown in FIG. 1 in that light momentarily entering the edge of eachlight conducting member 104 is conducted therethrough momentarily at the same time the entire assembly of thelight conducting members 104 is rotated inside of any housing.

The embodiment in FIG. 9 is similar to that of FIG. 7 and the primary difference is in the use of abelt 160 instead of adrum 106. In FIG. 9 a stationary, fixed inner drum orhousing 150 has astationary projection lamp 152 therein and there is aslot 154 through theinner drum 154. A transparent revolvingdrum 156 supported outside ofdrum 150 has acontinuous belt member 160 withslots 172 driven therearound and across a bottom drive means designated generally byreference numeral 164 and comprising adrive roller 166 which continuously drivesbelt 160.Belt 160 may be made from fabric or a combination of fabric and rubber or the like and has a plurality of metal brackets 170- a pattern ormessage 184 contained on the face of-each of thelight conducting members 174 or theymay be different colors or some other arrangement can be made.

In FIGS. 11 and 12 there is shown a version in which ordinary strobe lights such as Xenon tubes are used to provide pulsating light to the light conducting members. The device is designated generally byreference numeral 200 and comprises a box-like base 202 on which is mounted a motor driventurntable 204 from amotor 206 with ashaft 208 similar to the previous version in FIG. 1. Also similar to the previous version there are light conducting members of Plexiglas orother plastic 210 fastened to theturntable 204 with slots therebeneath through which light can be conducted to themembers 210. Mounted in dish-likelight reflecting reflectors 212 which may be made from brightly polished aluminum, stainless steel or mirror finished material of any kind, are Xenonstrobe light tubes 214 wired through respectiveelectric circuitry 216 and 218 to astrobe light pack 220 of conventional construction which has a source ofelectrical energy 221 and common electrical component means for flashing and pulsing thestrobe lights 214 at intervals. Such construction is common in the photographic field as well as other fields and ordinarily a capacitor is charged at intervals by current which stores a high potential of electrical energy therein that is immediately dissipated by opening the circuit to therespective bulb 214. Thebulbs 214 are timed and synchronized with the passage of theturntable 204 and thelight conducting members 210 to pulse through the respectivelight conducting members 210 in the pattern preprogrammed and preselected.

'In the version shown in FIG. 13, a box-like base 240 has amotor 242 therein driving ashaft 244 which includes acommutator segment 246 leading from a source of electrical energy through thecircuit 248 to thecircuit 250 which also leads throughcircuit 252 to themotor 242. The top of the base supports aplatform 244 on which are mounted thelight conducting members 246 similar to previous arrangements. Slots in theplatform 244 correspond to the edges of the respectivelight conducting members 246 and light through the slots is conducted through themembers 246 in a pattern as previously discussed. Alight bulb 248 is mounted in acompartment 250 in aturntable 251 attached to theshaft 244 whereby operation of themotor 242 turns theturntable 251 and carries with it the light 248 passing beneath the respective slots. By this arrangement the pattern is obtained as in the previous embodiments.

It will be obvious that there are other variations which are apparent to one having no more than ordinary skill in the art as for example in the embodiments of FIG. 1 or FIG. 13 it is possible to accomplish a pattern by placing the bulb, for example, 248 of embodiment, FIG. 13, stationarily on the base of themotor 242 and put preselected apertures in theturntable 251 which match at selected places and intervals with the edges of therespective members 246 or theplatform 244 could be made from plastic colored in proper places to be opaque, transparent or translucent.

In the illustrative diagram shown in FIG. 14 and 15 it is demonstrated that the more narrow the path of light through which the edge of the Plexiglas travels the briefer the pulse of light to which it is exposed and the more satisfactory the effect. In FIG. 14 aclear bulb 260 with afilament 262 covered by ashield 264 in which is anaperture 266 produces a pattern of confinement of light represented by the intersectinglines 268 striking theturntable 270. In the frosted bulb example in FIG. 15, afrosted bulb 280 with a filament 282 mounted beneath ashield 284 in which there is an aperturn 286 directs the path of light in confinement in a larger pattern represented by the dashed intersectinglines 288 which strike the turntable, 290,0n which is mounted the Plexiglas shaped light conducting member 292.

While I have shown and described a particular embodiment of this invention together with alternative forms thereof this is by way of illustration only and does not constitute any sort of concernment to any particular thing since the principle involved will apply to many different arrangements and therefore there are many alterations, changes, deviations, eliminations, additions, substitutions, omissions, departures and revisions which may be made in the forms shown herein without departing from the scope of my invention as defined in the appended Claims.
