Abstract

244,244. Siemens Bros. & Co., Ltd., Christian, D. A., and Patterson, W. G. Nov. 11, 1924. Addition to 200,928. Automatic exchange systems ; metering.-The delayed metering equipment described in the parent Specification is temporarily associated with the group selector over a finder switch CF when the called subscriber replies. Upon energization of answering relay Y, magnet DM is connected un over common wire 10 and rotates the finder switch until wiper C<1> engages the terminal grounded by relay L (which controls test relay T), whereupon relay TM operates, cuts the drive and closes a releasing circuit over wiper B' through winding 2 of relay L. Relay TM also provides an engaged test if more than one metering circuit is provided. Relay L on release connects up a resistance 15 to prevent relay TM reoperating once it releases. Relays S, Z operate in turn over springs controlled by cam 11 as in the parent Specification to close the metering circuit over wiper A', but relay Z does not hold and releases slowly, allowing relay TM to relapse.
