Adapter for use in non-lethal weapons and ammunition

Abstract

A telescopically expandable cartridge comprising an anterior portion 1 and posterior portion 2, the posterior portion 2 carries a first primer 3 which when initiated releases gases which propel a ball 4 along a channel 5 to impact upon a second primer 6 in the anterior portion 1. First primer 3 is configured for centre firing. The cartridge is located in the barrel of a weapon which has an off set firing pin 7. An adapter 8 is received in a recess in the posterior portion 2 to the rear of the first primer 3 and directly in front of the firing pin 7. The adapter 8 comprises a cylindrical body having an annular recess 9 provided around its outer circumference. An O-ring 10 is received in the annular recess 9. On an anterior surface of the adapter 8 proximal to the first primer 3 is provided a pointed protrusion 11 positioned centrally of the anterior surface.

1 . An adapter for translating an impact in an off centre location of the adapter to an impact in a centre location to facilitate the firing of a centre fire primer cartridge by a weapon with an offset firing pin. 
     
     
         2 . An adapter a claimed in  claim 1 , wherein the adapter comprises a rigid cylinder having a closed end on which is provided a centrally positioned protruding point.
