Abstract
449,675. Prepayment mechanism, for meters. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and TILSTONE, G., Siemens Works, Stafford. Dec. 31, 1934, No. 7077/36. Divided out of 449,556. Drawings to Specification. [Class 27] A setting member of the supply switch of a prepayment electricity meter is arranged to remain in the path of movement of an operating tappet of the coin mechanism when the switch is set, so that each time a coin is inserted, movement is imparted to the switch mechanism even if the switch is already set and the contacts closed, this resulting in a cleansing action being given to the contacts at each actuation of the mechanism. A prepayment mechanism incorporating the invention is described which is identical with that of Specification 449,556, to which reference is made. Specification 431,735, [Group XXXVII], also is referred to.
