Abstract
A structural member is interposed between the primary pellet and a charge, the structural member having upper and lower open-ended chambers formed by walls of the structural member which converge towards an opening generally centrally located within the structural member providing communication between the chambers. The upper chamber serves to convey the sparks emitted by the priming pellet to the charge disposed in the lower chamber.
Claims7
Device for point-ignition of a charge comprising a shell;
- a priming pellet at the top of said shell;
- a secondary explosive charge at the bottom of said shell;
- an initiating charge above and completely abutting said secondary explosive charge and a structural member within said shell interposed between said priming pellet and said initiating charge;
- said structural member including upper and lower chambers having sloping walls sloping outwardly substantially to the inner wall of said shell and an opening lying on the vertical axis of said structural member providing communication between said chambers, said upper chamber serving to convey the sparks produced by said priming pellet to said opening and said lower chamber being completely packed with said initiating charge and being symmetrical with respect to the vertical axis;
- the inner walls of said structural member forming said chambers converging towards said opening.
