Abstract: A coupling device for releaseably securing together two objects. The coupling device comprises a first housing securable to a first object, a second housing securable to a second object, and an actuator secured to the first housing. The second housing has a hollow bore therein. At least part of the actuator is releaseably receivable within the hollow bore of the second housing. The actuator has an activated and a deactivated configuration. When in its activated configuration at least a portion of the periphery of the actuator is in an expanded state such that when situated within the hollow bore of the second housing the expanded periphery of the actuator releaseably secures the first housing to the second housing. When the actuator is in its deactivated configuration the periphery of the actuator in a retracted state permitting separation and relative movement between the first and second housings.

Abstract: A drive mechanism for a transfer rail in a press transfer system having a drive frame for imparting reciprocating movement to the transfer rail. The drive mechanism comprises a drive housing securable to a transfer rail in the press transfer system, a drive bushing received and secured within the drive housing, and a drive member slidably received within the drive bushing and securable to the drive frame of the press transfer system such that movement of the drive frame causes movement of the drive member in a direction generally corresponding to the direction of the movement of the drive frame. The movement of the drive member is transmitted through the drive bushing to the drive housing and the transfer rail causing movement of the transfer rail in a direction generally parallel to the movement of the drive frame.
