Abstract
A quick acting clutch, the quick acting clutch comprising: a friction plate; a clutch plate movably mounted to the friction plate about a center of rotation of the friction plate and the clutch plate, the clutch plate being configured to rotate with respect to the friction plate; an actuator arm pivotally mounted to at least one of the friction plate or the clutch plate, the actuator arm being configured to amplify movement of a first end of the actuator arm and rotational movement of the friction plate relative to the clutch plate moves the first end of the actuator arm; and a lock pawl pivotally mounted to the clutch plate for movement between a locking position and an unlocking position, the lock pawl and a second end of the actuator arm each being configured to contact each other and rotational movement of the friction plate with respect to the clutch plate causes movement of the first end to be amplified at the second end such that the second end of the actuator arm and the actuator arm contacts the lock pawl and the lock pawl is moved from the locking position to the unlocking position.
