Abstract

462,813. Electric light reflectors. HAWKINS, J. C. Oct. 1, 1936, No. 26612. [Class 75 (ii)] A pyramidal reflector of triangular cross section is mounted directly upon an eleclight bulb and consists of an outer case formed from a onepiece metal blank and lined with substantially triangular pieces of silvered glass e. The latter are cut away at the top along circular arcs, and are held in position by the turned-over lower edges a and upper tongues f of the outer case. The neck of the bulb protrudes through the aperture in the reflector so as to allow some light to pass upwardly, and the formation of the aperture allows the reflector to be ventilated.
