Abstract

269,760. Stimson, J. C. July 2, 1926. Reflectors.- A method of forming central triple reflectors, of the kind described in Specification 270,790 consists in using a moulding-surface or matrix formed by the ends of a number of bars assembled side by side and clamped together, the ends of the bars being suitably shaped to produce a reflector of the desired configuration. In making the reflectors by pressing glass, the press plunger consists of a number of steel bars 3, Fig. 1, hexagonal in cross section, which are clamped in the press head, as shown. The lower ends of the bars are bevelled off to form a series of cubic formations that produce a surface of which each reflecting unit 63, Fig. 7, consists of three sides of a cube. The bars may be of other suitable shapes, and as shown in Fig. 12, square bars with ends perpendicular to their axes may be assembled in an inclined position in the body 50 of the mould. Hollow reflectors may be made by depositing metal electrolytically on a pressed glass plate, formed as described, or on a matrix formed by elements similar to the bars 3.
