ABSTRACT:
A safety means for an ordnance fuze. The arrangement includes an arming rotor (1) which is held in a safe position (A) by means of a half-shaft (6) which in the safe position of the rotor engages a first recess (7) located in the rotor. A clock mechanism (9) is provided so as to rotate the half-shaft (6) about its axis to a rotational position in which it no longer engages the rotor (1), thereby enabling the rotor to be rotated to its armed position. The rotor has provided therein a second recess (11) into which the half-shaft (6) is able to rotate should it be rotated at an excessively high speed, thereby returning the rotor to its safe position.
