[Class 80 (ii).] In an electromagnetic friction clutch one element comprises field and armature members connected together by a spring disc and arranged to clamp between them the other element which also has a spring disc mounting. Two or more annular windings arranged to produce separate magnetic cir. cuits may be provided to reduce the self-inductance and thus facilitate the release of the clutch. The field member 5 bolted to the driving hub 3 carries the annular winding 11 and the friction disc 15. A second friction disc 26 is secured to the field member 6 which is mounted upon an extension 22 of the field member 5 by a spring disc 20. A third friction disc 7 is carried by a ring 28 connected to the driven hub 4 by a spring ring 29. When the circuit of the winding, which is connected to slip rings 13, 14, is closed the ring 7 is thus clamped between the rings 15, 26. The rings 7, 15 are adjustably mounted on the parts 5, 28 respectively by screw plugs 34 within which cap screws 35 are rotatable. A nonmagnetic shim 36 prevents contact between the field and armature members 5, 6. In a modification, two concentric windings, in which the current flows in opposite directions, are provided and the armature member is formed with a ring that projects between the two windings. Self-inductance is thus reduced. The field member is shown as secured to a driving pulley in this construction.
