Abstract

525,830. Electric battery lamps. PEILL, D. M. March 1, 1939, No. 6707. [Class 39 (ii)] Several lamp bulbs 8 are mounted on a spindle 11 so that by rotation of a knob 13 any bulb can be brought into operative position. The bulbs can be differently coloured, or differently focused or be used as spares. Only the bulb in operative position is in circuit with the battery by contact of strip 17 with strip 28. Each bulb is surrounded by a part reflector 14, the other part 5 being fixed and being common to each bulb.
