Abstract: A coin mechanism for producing one or more pulses responsive to a coin having been received into the mechanism. The number of pulses is representative of the value of the coin received. Coins of different values are channelled into different paths, each path holding its coin for a sufficiently long period of time to allow the correct number of value indicating pulses to be transmitted.

Abstract: A telephone pay station central system in which answering of a call originated at the pay station causes the generation of a signal from the central office to the pay station to connect the coil collection and value-indicating network to the line loop. A coin collection relay is thereby energized to collect a coin and to cause a pulse to be returned to the central office indicating that the call can continue. Periodic back-and-forth signalling continues as necessary during the conversation period without disrupting the conversation.
