Abstract

504,723. Interrupters. BRITISH THOMSON - HOUSTON CO., Ltd., GRIFFITHS, L., and MASTERS, A. W. Oct. 26, 1937, No. 29265. [Class 38 (v)] In a magneto-electric machine having a contact make-and-break device operated by a pivoted arm 2, rocked by a cam 1, timing of the spark is effected by varying the extent of the gap of the make-and-break device, variation of the length of gap being effected by mounting the fixed contact 11a of the device on a rod 14 which can be moved by rotation of a screwed sleeve 20, towards or away from the movable contact carried at the free end 2b of the arm 2. The rod 14 is slidably mounted in an insulating bush 11 carried in the reduced end of a bore extending through the casing of the device and into which the sleeve 20 screws, the rod being urged outwardly against a gap-adjustment screw 19 by a spring 16 surrounding the rod and which presses at its ends respectively against the bush 11 and a collar formed on the end of the rod. An insulating cap 17 insulates the rod from the screw 19 and the latter is carried by the sleeve 20. The sleeve 20 is angularly adjusted by a lever 21, which is preferably provided with pre-set positions corresponding to advance and retard timing. A " stop " position may also be provided in which the contacts are per. manently closed. Alternatively, the lever may be spring-biassed so that it always tends to turn into the " stop " position.
