Abstract
The armature of an electromagnetic clutch is connected to an axially fixed elastomeric ring by leaf springs which urge the armature away from the electromagnet. Rivets connect the springs to the armature and are formed with pin-like extensions which are telescoped snugly but slidably into holes in the ring. When the magnet is initially excited, the ring frictionally retards movement of the pin-like extensions to cause the armature to softly and quietly engage the magnet rather than slapping sharply against the magnet.
