Abstract

459,375. Oscillating motors. CLAYTON, C. E. EVERY-, 51, Chancery Lane, London.-(Merk Telefonbau Akt.-Ges., F. ; Munich, Germany) Aug. 10, 1935, No. 22634. [Class 35] [See also Group XXXIX] A meter-controlling device for a telephone system comprises a disc assembly which may be stepped in either direction by magnets DR, DV. The armature lever H2 of each magnet controls the holding pawl S1 of the ratchet disc stepped by the other magnet by means of a stop P2 engaging a pivoted lever Z1 in such a way that when the driving pawl A2 is operative the holding pawl S1 is withdrawn, the stop P2 then slipping past the lever so that the pawl is reinserted.
