ABSTRACT:
A flap-type indicating device includes two, co-axially mounted indicator assemblies and a resilient synchronizing element interposed therebetween for insuring the synchronous changing of the indicator elements upon the two assemblies at a predetermined time. A cam member, integrally formed upon the rotatable drum of one of the assemblies, is provided for axially biasing the synchronizing element toward the other one of the assemblies so as to prevent the changing of the indicator device prior to the predetermined time, and a lug member is operatively associated with one of the flaps of the first assembly for continuing the biasing action of the synchronizing element towards the other indicator assembly after the cam member has been released from the synchronizing element and until the occurrence of the predetermined time.
