Abstract

1397069 Switch actuation; electric motor controllers WESTLAND ENGS Ltd 20 Oct 1972 [1 Nov 1971] 50631/71 Heading H1N In a device for switching off an electric motor when a clutch in its driven system begins to slip, at least two switches 18, Fig. 1, in circuit with the motor are normally maintained closed against a pneumatically delayed return by a rotary multi-lobed cam 17 and which permits at least one of the switches to open when it ceases to rotate. In the example the cam 17 is coupled to one of the sprocket wheels (40) Fig. 3 (not shown) of a chain drive for a sliding door (30). When the door reaches either end of its travel the sprocket wheel (40) and cam 17 are no longer free to rotate so that the clutch slips and the motor is switched off.
