Abstract
382,780. Electric lampholders. McGILP, D., 4, St. Andrew's Square, Greenock. Nov. 27, 1931, No. 32882. [Class 39 (ii).] To prevent theft or unauthorized removal of an electric lamp 6 from its socket 1, a substantially elliptical spring clip 5 is disposed on the cap 3 of the lamp in the recess formed between the lower edge of the socket 1 and the ridge 4 of the cap. The clip 5, which is of such thickness as to prevent normally the disengagement of the bayonet joint 2, may be released by applying pressure to the ends 8 of the clip. In cases where the cap 3 has no ridge 4, the clip is interposed between the lower edge of the socket 1 and the upper edge of the lamp bulb.
