Abstract: A fuse provided with two striker-and-detonator systems, one of which operates upon impact against a target and may be manually locked against operation and the other operates only with a predetermined lag after impact. The first system is adapted to be brought in all cases into a ready-for-operation condition at the moment of the firing of the missile, in which condition the member carrying the detonator of the first system is brought within reach of the corresponding striker while it simultaneously releases a safety interceptor extending between the striker and detonator of the system operating with a lag.

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.
