Impact fuse for a spinning projectile

Abstract

Abstract A PRECUSSION FUSE FOR SPINNING PROJECTILES WHICH COMPRISES A CASING HAVING A FRONT PART AND A REAR PART AND A SLEEVE SECURED IN THE REAR PART OF THE CASING AND HAVING A BEARING SURFACE. A BALL CARRIER WITH BALLS IS MOUNTED SLIDABLY IN THE CASING AND IN THE SLEEVE AND HAS A STRIKER PIN THEREON. A FUSE BODY IS SECURED IN THE REAR PART OF THE CASING AND SPACED ON THE SLEEVE. A ROTOR IS MOUNTED TO ROTATE BETWEEN THE FUSE BODY AND THE SLEEVE AND HAS A COILED BAND AROUND THE ROTOR AND HAS A PERCUSSION CAP THEREIN. A FUSE PLUNGER IS SLIDABLY MOUNTED IN THE CASING AND EXTENDS INTO THE SLEEVE. THE ROTOR IS NORMALLY HELD IN INOPERATIVE POSITION BY THE COILED BAND AND WHEN THE PROJECTILE IS FIRED A CENTRIFUGAL SPINNING FORCE WILL ACT ON THE BAND TO HOLD THE ROTOR IN AN UNARMED POSITION FOR A PREDETERMINED PERIOD OF TIME, SO THAT WHEN THE BALLS IN THE BALL CARRIER FORCE THE LATTER AWAY FROM THE ROTOR, THE STRIKER PIN WILL BE IN POSITION TO PLUNGE INTO THE PERCUSSION CAP WHEN THE PROJECTILE STRIKES A TARGET. THE COILED BAND SURROUNDS AT A DISTANCE THE ROTOR IN ITS INOPERATIVE POSITION, AND A LOCKING PIN IS DISPOSED RADIALLY AND BRIDGING THE DISTANCE ENGAGING THE INNER COIL LAYER OF THE COILED BAND AND ENTERING A RECESS OF THE ROTOR SUCH, THAT THE RELEASE AND ERECTION OF THE LATTER IS POSSIBLE ONLY, WHEN THE INNERMOST COIL LAYER HAS EXPANDED AT LEAST FOR THE AMOUNT OF DEPTH OF PENETRATION OF THE LOCKING PIN INTO THE RECESSES.
