Abstract
647,605. Signs. MACHARG, J. A. May 26, 1948, No. 14180. [Class 3(ii)] Non-opaque display objects are mounted on a base plate so that light from an adjacent illuminating means can pass through this base plate to illuminate the objects, the outer ends of which have one or more non-opaque laminations arranged parallel to the base plate, one at least of the laminations being of semitransparent plastic. A body 1 of clear plastic but with the sides roughened is faced with a semi-transparent white plastic layer 2 on top of which is a clear coloured layer 4. The base of the symbol has similar laminations 3, 5. The symbol may be mounted in a cut-out in a base plate A so that the front of the lamination 3 is level with the front of the base plate. The base plate may be opaque except behind the symbol and may be illuminated from behind or from one or more edges. Each symbol may be mounted on individual base plates which are mounted in a common frame and which have rabetted edges to prevent escape of light. The semi-transparent layers 2, 3 act as a light shield in daylight when the symbols are not artificially illuminated. The body portion 1 of each symbol may be constructed from plastic sheets arranged in the form of a box.
