Abstract
289,619. Murray, R. H. April 7, 1927. Reflectors.-Light reflecting devices or units 7<a> are provided with abutments 9 to enable them to be readily positioned in apertures 10<a> in the frame or holder of an indicator or advertising sign. The abutment is formed by a flange 9 on the base 7, which acts as a protector to the reflector. Rubber washers 11 render the joints watertight; and similar washers 13 act as packing between the base and base plate 12 of the device. Specifications 194,034 and 256,475 are referred to.
