Abstract:
An indexing mechanism for playing a plurality of messages on a phonograph record sequentially by stopping the record at predetermined reversely-rotated positions following playing of each message. A first stop on the record engages a third stop on a carrier frictionally coupled to the record for movement thereby during reverse rotation until a second stop interrupts movement of the carrier with the record coincident to movement of the third stop into the path of travel of the first stop. The carrier again moves with the record during forward movement thereof to move the third stop out of the path of travel of the first stop when the next message is played.
