1,166,349. Electrically operated brakes; friction clutches; controlling clutch/brakes combination. J. MIQUEL. 16 June, 1967 [22 June, 1966], No. 27819/67. Headings F2C, F2E and F2L. A magnetic coupling member comprising at least one annular array of ferromagnetic members 41 mounted for axial movement on a support plate 30 which is carried by a shaft 36 is characterized in that the ferromagnetic members are bonded together by radial bonding layers incorporating a dry lubricant. In one embodiment, Fig. 1, the plate 30 carries two ferromagnetic rings 41, 42 which are axially movable on pins 43, 40 protruding from the plate 30. Each ring is formed as a number of segments which are bonded together by radial layers (44, 45) Fig. 2 (not shown) of thermosetting resin having a good coefficient of friction, e.g. lead or molybdenum graphite. Mounted adjacent this member is a fixed member 31 carrying two electromagnets 32, 33 and arranged between the two members is a further ferromagnetic plate 37 attached to a driving shaft 34. The plate 37 has ventilation holes 38, and either the plate 37 or 39 may act as a cooling fan. The shaft 36 may either be braked, or coupled to shaft 34 by actuating electromagnet 33 or 32 respectively. In a modification, Fig. 3 (not shown), the electromagnet 32 is mounted for rotation with the shaft 34, and the plate 37 is omitted.
