Abstract
1,260,322. Locks. G. F. WHITELEY and V. E. BOXALL. 16 April, 1970 [30 Sept., 1969], No. 47921/69. Heading E2A. The door or cover 3 of a dangerous machine is locked by a key which is captive in the door and engages in and operates an axial-pinplunger type lock in the door which is connected to the machine-operating spindle 29. The key 9 is held by a body 1 which is fixed to the door, and carries an operating knob 5. The key slides axially in the body 1 and has a bored end 10 which fits over a projection 28 on the lock rotor and has laterally projecting ears 11 which locate it in a body 25 on the door frame 20 when inserted and rotated, Fig. 4. In the closed position, bevels 18 and 25 are mated and the key has end notches appropriate to the lock tumblers 27. Springs 31 engaging flutes 30 in the key spindle serve to index it. The key may be partly countersunk as at 3a (see also Fig. 6, not shown).
