<p>A spring operated clutch having an input subassembly and an output subassembly. The input subassembly includes a sleeve member fixedly interconnected with an input drive shaft and provided with a double conical resilientfrictional member on an outer cylindrical surface thereof. A first brake member is movably disposed within a bore of a second brake member, each of the brake members having frustoconical surfaces cooperating with one of two frustoconical surfaces of the frictional member. An adjusting member is movably interconnected with one of the brake members and a spring is interposed the adjusting member in the first brake member so as to bias the brake members into engagement with the friction member. The output subassembly includes an annulararmature member having a first set of teeth extending therefrom and engageable with a second set of teeth which extend from the first brake member. The armature member is movably interconnected with the magnet body which, in turn, is fixedly interconnected with the housing. Springs bias the armature into engagement with the second brake member while an electromagnetic coil in a magnet body is selectively operable to overcome the biasing force of the springs to disengage the first and second set of teeth.</p> |
