Three dimensional space viewing device

Claim 1

A three dimensional viewing device for creating the illusion of space vehicles moving in interplanetary space comprising: a housing means having a viewing opening in the front surface thereof and a viewing chamber in the interior thereof; said housing having a base, a plurality of upwardly extending walls, a top, and a chamber therein, one said wall having said large viewing opening therethrough; a plurality of bearing blocks mounted on said top and said base within said chamber; a first spindle rod vertically disposed in said chamber, the ends of said first spindle rod journaled in a first pair of said bearing blocks; a second spindle rod vertically disposed in said chamber, the ends of said second spindle rod journaled in a second pair of said bearing blocks; a first cylindrically shaped drum member mounted on said first spindle rod; a first pulley member mounted on said first spindle member; a second cylindrically shaped drum member mounted on said second member; an electric motor having a vertically upwardly extending drive shaft, said motor disposed in said chamber; a second pulley member disposed on said drive shaft; a V-belt communicating between said first and second pulley members; a continuous movable black belt member having planetary scenes painted thereon in paints sensitive only to ultraviolet light vertically oriented and disposed toward the rear of said viewing chamber, visible from the front of said chamber, and forming a background scene; said belt member engaging around said first and said second drum members such that the activation of said electric motor will cause said continuous black belt member to revolve around said drum members providing a continuous background scene in the vertical plane; at least one foreground picture member in vertical alignment with said background scene vertically mounted in said chamber forward of said continuous black belt, said foreground picture member having cutouts to permit the viewing of said black belt; ultraviolet light means positioned to illuminate said background black belt; fluorescent light means positioned to illuminate said foreground picture member; said foreground picture members are held in vertical alignment with said background scene by a means comprising: a pair of channel members; said channel members affixed vertically to opposed interior surfaces of the side walls of said housing; and each of said channel members being capable of receiving the outer side edges of said picture members therein.
