Abstract
Abstract An actuator assembly of the type for moving a flexible transmitting core element in a curved path including a housing comprising a plastic half covered by a metal plate. The plastic half has a circular cavity for receiving a circular drive wheel which has a groove circumferentially thereabout for receiving the core element. The plastic half has a pocket and a plastic bushing is disposed in the pocket. A rod extends through the housing through the plastic bushing and through an arcuate slot in the circular drive wheel and into threaded engagement with the metal half of the housing whereby upon rotation of the rod the bushing is urged into frictional sliding engagement with the circular drive wheel for controlling the rotation thereof or to act as a brake. The housing also has a channel extending therethrough across the top and a core guide disposed in the channel. The channel has an enlarged portion adjacent each end and the guide includes a shoulder disposed in one of the enlarged portions. An insert is disposed at the other end of the channel and has a shoulder at the end thereof which is in abutting engagement with the other end of the guide, the insert and guide having passages therethrough through which a core element extends to engage the peripheral groove in the circular drive member.
