Abstract: A safety device for a gyratory rocket missile of the type with a primer support centrifugally pivotable from a safe to an armed position and centrifugally releasable means for securing the support in the safe position, comprises an axially slidable pin urged by a spring to a position locking the securing means in support-securing positon. The two ends of a resilient open loop releasably engage a groove in the pin to hold it in the locking position and, when the pin moves due to an axial acceleration upon firing the missile so as to free the securing means, the ends of the loop come to bear against a shoudler of the pin to prevent return thereof. Once the support regulated by a delay mechanism reaches the armed position, a finger slidably mounted in an outwardly opening radial housing in the primer support moves out of its housing to lock the support in position.

Abstract: THE FUZE, E.G. FOR A MORTAR, CAN BE DETONATED INSTANTANEOUSLY ON IMPACT OR, BY PREVIOUS ADJUSTMENT, WITH A TIME DELAY, THE FUZE HAS A PRIMARY FUSE FOR DETONATION ON IMPACT BY A FIRING PIN BUT IS HELD SPACED FROM THE LATTER BY A LOCKING DEVICE WHICH CAN BE UNLOCKED BY THE AXIAL ACCELERATION DUE TO DEPARTURE OF THE SHOT. THE FUZE ALSO HAS A DETONATOR SAFETY DEVICE COMPRISING A SECONDARY FUSE AND A HOLDER MOVABLE TRANSVERSALLY TO THE AXIS OF THE FUZE TO BRING THE SECONDARY FUSE OPPOSITE THE DETONATOR. TIME DELAY OF THE SECONDARY FUSE IS PROVIDED BY A CLOCKWORK MOVEMENT ROTATING A TOOTHED SECTOR. A SECOND FIRING PIN FOR THE SECONDARY FUSE ACTS AS A STOP BLOCKING THE

TOOTHED SECTOR IN INACTIVE POSITION. THE SECOND FIRING PIN IS BORNE BY A PLUNGER SLIDABLE AXIALLY IN THE FUZE. A BALL BLOCKING MECHANISM FIXES THE PRIMARY FUSE HOLDER AND THE PLUNGER RIGIDLY TO ONE ANOTHER AS LONG AS THE PROJECTILE HAS NOT UDERGONE IMPACT AFTER DEPARTURE OF THE SLOT. IMPACT RELEASES THE BLOCKING BALLS ENABLING THE PLUNGER AND THUS THE SECOND FIRING PIN TO BE DRIVEN BACK BY A SPRING, WITH THE TIME DELAY, AGAINST THE SECONDARY FUSE.
