Title: Overload release clutch

Abstract: A torque limiting device such as an overload release clutch which releases completely when an overload condition is reached. Torque transmitting means in the form of a plurality of balls shiftably mounted in detents are spring loaded to the driving position, thus providing a torque sensitive drive connection between the input and output members. The clutch also includes means for insuring complete torque release between the input and output members as soon as the predetermined torque load is reached, and complete torque release is maintained until the clutch is manually re-engaged.
