Abstract

833,676. Lamp-holders. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 16, 1956 [July 19, 1955], No. 21906/56. Class 38 (1). A multiple holder for photographic flashbulbs comprises a disc-shaped insulating body 3 having a series of apertures therein in which are fitted sleeves 11, each carrying opposed, curved contacts 17, 18 and forming a holder for a flash-bulb. The body 3 also has a central projection 4 on one side over which is fixed a cap 20 by means of a bolt 23 which is insulated from the cap by a washer 25. The cap carries bayonet pins 21, whereby the assembly may be engaged in the bayonet holder of a standard flash apparatus, and is rotatable on the projection 4, being located in any of six positions by a spring-loaded ball 30. In each of said positions, a contact strap 40 carried by the cap engages an extension 38 of one of the contacts 18, the contacts 17 being connected together by a ring 33 and to the holt 23 by a conductor 34. Thus with the holder plugged into a flash apparatus, a number of lamps carried thereby may be brought successively into the flashing circuit by rotating the body 3. The holder may carry a reflector.
