Abstract

523,192. Monogrammic signs. NEOGRAPH, Ltd., and KNEPPER, F. Dec. 23. 1938, No. 13409/39. Divided out of 523,042. [Class 118 (ii)] Relates to a sign of the kind in which a group of tubular electric lamps or discharge tubes are arranged to display letters, numerals, etc., by selective illumination, of one or more tubes. According to the invention a sign of this type comprises straight lighting - elements of three standard lengths only, as shown, and the arrangement of the tubes is such that each letter displayed is represented by a different selection of tubes, so that no two letters can be mistaken for one another. The tubes are connected to a keyboard or switch, preferably a rotary switch of the kind described in Specification 523,042. The lighting elements may be discharge tubes or tubular incandescent lamps, or linear batches of ordinary incandescent bulbs on straight supporting-units.
