Candles, imitation; caps; holders.-A tubular standard f attached to a plug h is threaded externally to receive an adjustable screw holder for a lamp a having a shoulder a<1> at one-quarter or more of the length of the bulb from the cap. An opal glass tube b is pressed against the shoulder by a washer n and coil spring o bearing on the plug h. A split pin d on the lamp cap enters the standard, which consists of co-axial insulated tubes; or the pin may be threaded and the lamp-cap plain. The holder may be locked on the stem by a nut m. The plug h is provided with contacts and bayonetjoint pins i, or with a screwthread. According to the Provisional Specification, the screw holder may be replaced by a bayonet-joint holder, which may have indentations or spring fingers to assist in clasping the lamp. Reference h a s b c e n directed by the Comptroller to Specification 24971/12.
