Abstract

453,044. Electric -battery lamps. BAILEY, J. N., 27, Chancery Lane, London.- (Yu, C. T. ; c /o Ling Nam Hardware Manufacturing Co., North Point, Hong Kong) July 31, 1935, No. 3625/36. Divided out of 453,016. [Class 39 (ii)] An electric torch or battery lamp is provided with an extensible casing to enable the battery capacity to be increased or decreased by the insertion or removal of cells which form part of the circuit. A variable resistance is also provided to regulate the voltage applied to the lamp bulb. The example shows a telescopic metal casing comprising an upper portion 4 with screw-threads 44 around its lower end, and a lower portion 45 which is screwthreaded at the top 46 and near the bottom at 47, so that either of the spaced sets of screw threads in the lower portion can be engaged with the threads 44 of the upper portion. As shown, the casing is in its contracted position, with the threads 44, 47 in engagement. A bottom cap 48 screwed on the lower end of the casing carries a housing 50 containing a resilient contact 49 which holds the cells in position. The resistance regulator comprises a contact arm 37 mounted upon a centrally pivoted disc 32 of insulating material provided with an operating button 40 projecting through a transverse slot in the casing, the end of the contact arm 37 being adapted to bear upon a resistance wire 31 wound upon an arcuate former. Connection between the contact arm 37 and the battery is provided by a screw 36 with its head in contact with the centre pole of a cell 42 and its shank bored to receive a screw 39 which holds the contact arm 37 and disc 32 in position. A metal strip 33 connected to one end of the resistance 31 is connected by a flexible wire 20 to the centre contact 21 of the bulb socket 18, the other end of the resistance being connected to a metal strip which is connected to the metal shell of the bulb socket and also to the casing 4 through a switch 43. Specification 453,016 is referred to.
