Abstract
An internal overload clutch assembly is provided for connecting rotating and rotatable members during normal operation and for disconnecting same when a maximum predetermined torque is exceeded, all of the operating components being mounted within an enclosed housing and including a rotatable member which is rotatably mounted within the housing and has output means extending outside the housing to perform mechanical operations. A rotating member is rotatably mounted on the rotatable member in the housing and is operatively connected to a power source for predetermined rotational movement thereof. An internal overload clutch assembly cooperates with the rotating and rotatable members within the housing and includes drive and driven collars, the drive collar being attached to the rotating member while the driven collar is attached to the rotatable member, the drive and driven collars being coupled and uncoupled relative to one another through axially shiftable detents which couple the drive and driven collars together during normal operation, while uncoupling the drive and driven collars when an excessive predetermined torque is encountered in performing prescribed mechanical operations outside of the housing.
