Abstract

525,632. Supporting reflectors, VERITYS, Ltd., and CHAPMAN, F. E. Feb. 24, 1939, No. 6133. [Class 75 (ii)] In electric lighting apparatus in which the crown 1 of a reflector is detachably clamped between a rigid cap 8 and a spider 14, the latter screws up and down on the cap with the reflector when the latter is rotated. The spider 14 screws on to a stem 11 forming part of the cap 8. A screw 10 locks the spider in the clamping position. The reflector crown 1 is flanged inwardly and downwardly at 16 and 17, and has notches formed in the flanges so that, when the spider is in the lower position, the crown can be passed over the legs of the spider and brought into a position in which its rotation causes the spider to rotate. The lower part of the reflector may be integral with or detachably connected with the crown 1. Integral with the cap 8 is a wiring box 4.
