The IBM SELECTRIC Composer: Development of the Rebound Governor

Rebound of the escapement system of the SELECTRIC Composer after escapement is limited by the rebound governor, a device consisting of an overrunning clutch and a mass that is coupled to the system only during rebound. The development of the rebound governor is described in this paper and its effect on the escapement system is shown by oscilloscope traces of system displacement versus time.
