Abstract

1475070 Safety locks UNIMAX SWITCH Ltd 19 March 1975 59003/73 Addition to 1260322 Heading E2A A safety device as disclosed in Specification 1260322 (Division E2) incorporates a locking sliding bolt 8 for locking the captive key 1 in its lock-engaged position. The safety device e.g. mounted on a guard cover 13, comprises a knob 4 that, when pressed against a spring 5 and then rotated, pushes the captive key 1 into operative engagement with a lock/switch 11. The locking bolt 8 is urged by an eccentric 14 into an aperture 16 in a fixed mounting 2 of the safety device, the eccentric being rotated by rotation of the barrel of a barrel lock 6 on insertion of a removable key 9. The locking member 8 can engage the aperture 16 only when the knob is suitably pushed and rotated, and the key 9 can be removed from the barrel lock 6 only when the locking member 8 engages the aperture.
