| abstract |
AN ILLUMINATED DISPLAY CHARACTER FOR A SIGN IS FORMED WITH A RECTANGULAR TRANSLUCENT COVER DETACHABLY SECURED TO A SIMILARLY SHAPED BODY UNIT AND OVERLYING AN ELECTRIC LAMP WHICH IS HOUSED WITHIN THE BODY UNIT TO ILLUMINATE THE CHARACTER. PART OF THE COVER IS DARKENED WITH OPAQUE MATERIAL ARRANGED TO OUTLINE AN INTELLIGIBLE TRANSLUCENT LETTER OR NUMBER LOCATED CENTRALLY OF THE FACE AND ILLUMINATED BY THE LAMP. BY REPLACING ONE COVER ON THE BODY UNIT WITH ANOTHER OF THE SAME SIZE AND SHAPE AND FORMED WITH A DIFFERENT TRANSLUCENT LETTER OR NUMBER, THE SAME BODY UNIT AND LAMP MAY BE USED TO DISPLAY VARIOUS LETTERS AND NUMBERS. |
