Abstract

277,474. British Thomson-Houston Co., Ltd., and Cocksedge, F. M. Aug. 17, 1926. Reflector holders; securing reflectors to holders.-The outer end of the tapered neck h of a reflector has an in-turned flange j cut away to provide radial portions j<1> having bentover long and short end projections k, k<1> engageable with radial arms d on a flange c at the lower end of a bush b. The bush b is secured, as by means of screwing, to a wiring or other conduit conveying illuminant to the lamp, and to the upper end of the bush is secured a detachable cap a in the form of a sheet metal stamping or spinning. When assembled in position, the arms d are held between the projections k, k' by means of a spring- pressed loose annular plate c surrounding the bush b between the flange c and the cap a. A lamp holder g may be secured to the underside of the flange c by means of screws g<1>.
