Abstract:
1. A clutch mechanism for a door having a lockset with a lockable latch and actuator for operating the latch, the clutch mechanism comprising: an input cam; an output cam; an engagement pin having an axis and being dimensioned and configured for axial movement between a first position, in which the engagement pin engages both the input cam so that the input cam and output cam rotate synchronously, and a second position, which allows independent rotational movement of the input cam and the output cam; a movable camming surface cooperating with the engagement pin to move the axial position of the engagement pin between the first position and the second position; override means biasing the position of the camming surface towards an override position to force the engagement pin to the first position; and a removable interchangeable core, the core when installed blocking the override means from forcing the camming surface toward the override position, the core when not installed allowing the override means to bias the camming surface to the override position; wherein the override means includes a coil spring.
