Abstract: An electro-slip clutch may include a friction stack for receiving input rotation from an input shaft and a surrounding hub and for attaching to an output member. A bearing surface may be provided adjacent the friction stack and a solenoid may further be provided. The solenoid may include a plunger in a first position pressing against the bearing surface with a first degree of force and in a second position different than the first position relative to the bearing surface. Thus, torque transmitted through the friction stack is adjustable by the solenoid. A method of operating a clutch mechanism may include providing a solenoid adjacent a friction stack and providing a first current level to the solenoid, the first current level energizing a coil of the solenoid and pushing a plunger within the solenoid towards the friction stack with a first degree of force.

Abstract: A mechanism useful as a slip clutch or brake, including a first member having a cylindrical inner wall, a second generally cylindrical member received coaxial within the first member so as to be rotatable therein, and at least one generally annular third spring member between the first and second members, the at least one third member having an external surface in contact with the inner wall of the first member, the second member having at least one longitudinal recess defining two wall surfaces, the at least one third member having ends extending inwardly into the at least one recess, each of the ends of the at least one third member contacting the wall surfaces.

Abstract: An operating handle for a winch having a four or eight-sided socket which comprises a hand engaging portion, a lever arm and a socket driver, the driver being of square shape and having a spring loaded detent therein arranged to extend outwardly of a side of the driver and engage a wall of a socket, the detent being positioned off-center of the vertical center line of the side of said driver and so positioned as to engage on a wall of an eight-sided socket.

Abstract: A cone clutch comprising a housing member defining an internal frustro-conical surface, an internal member having an mating frustro-conical exterior surface received within the housing member, the housing member and the internal member being relatively rotatable, a layer of friction material is disposed between the frustro-conical surfaces and is unbonded to either surface, and means are provided for biasing the internal member into engagement with the frustro-conical surface of the housing member.
