Abstract
322,356. Siemens Bros. & Co., Ltd., and Christian, D., A. Dec. 14, 1928. Automatic exchange selectors. -The wiper tips 2 of a selecting mechanism are fixed loosely on the wiper carier 4 to ensure that vibrations in the shaft do not affect the connection between the tips and the terminal bank. The part 2 passes through a hole in the carrier 4 and is fixed thereto by the rivet 3. The wipers in Fig. 1 make contact between two terminal banks whilst in Fig. 4 the tips are arranged to grip a single terminal.
