Abstract

286,022. Lithgoe, J., and Tinsley, H. Dec. 9, 1926. Protective systems.-For the protection of a number of electric motors working coal-conveyors or cutters in a mine, a master switch L in a lowtension earthed circuit controls solenoids K<1>, K<2>, &c. operating the motor switches H<1>, H<2>, &c., with electrical interlocks arranged so that the motors must start successively in a given order and, in the event of a fault, the faulty motor is switched out together with the motors that come after it in the order of starting. As a modification, the system may be arranged so that a fault on any one motor occasions the switching out of all. Specification 248,805 is referred to.
