Traveling placard character display apparatus

Abstract

Abstract A NOVEL TRAVELING PLACARD CHARACTER DISPLAY APPARATUS IS DISCLOSED, THE APPARATUS BEING OF THE TYPE WHEREIN A PLURALITY OF ADJACENT COLUMNS OF DUAL-FACED INDICATING PLATES ROTATABLY DISPOSED ABOUT RESPECTIVE SUPPORT SHAFTS ARE MOVABLE OVER AND BEHIND AN INDICATING SURFACE WHICH PROVIDES AN ENVIRONMENT OPTICALLY CONTRASTING WITH BOTH FACES OF THE INDICATING PLATES. THE TWO FACES OF EACH INDICATING PLATE ARE THEMSELVES OPTICALLY CONTRASTING AND A PREDETERMINED CHARACTER CAN BE DISPLAYED ON THE INDICATING SURFACES DEPENDING UPON WHICH FACE OF THE INDICATING PLATES IN THE PLURALITY OF COLUMNS ARE DISPOSED TOWARD THE INDICATING SURFACE. EXTINGUISHING MEANS ARE PROVIDED ENSURING THAT EACH INDICATING PLATE IS INITIALLY ORIENTATED SUCH THAT A GIVEN FACE OR SIDE THEREOF FACES THE INDICATING SURFACE. READ-IN MEANS THEN SERVE TO ROTATE SELECTIVE ONES OF THE INDICATING PLATES SO AS TO ALTER THEIR ORIENTATION. THE INDICATING PLATES OF THE INSTANT INVENTION COMPRISE TWO MOLDED PLASTIC FACE PORTIONS OF OPTICALLY CONTRASTING COLOR WHICH ARE INSERTED TOGETHER IN SURROUNDING RELATIONSHIP ABOUT COLLARS FORMED ON THE SUPPORT SHAFTS BETWEEN PERIPHERAL GROOVES. ONE OF THE PLASTIC FACE PORTIONS OF EACH INDICATING PLATE IS PROVIDED WITH A REVERSING CAM MEANS WHICH EXTENDS OUTWARDLY TRANSVERSE BOTH TO THE AXIS OF THE SUPPORT SHAFT AS WELL AS TO VISUAL FACE PORTION AND COOPERATES WITH BOTH THE EXTINGUISHING MEANS AND THE READ-IN MEANS IN A NOVEL FASHION SO AS TO AID ROTATION OF THE ASSOCIATED INDICATING PLATE.
