Abstract

A projectile having a chamber containing a propellant charge with an electric igniter and also having a chamber containing an explosive charge with a time delay fuse. The chambers are separated by a wall in which there is a firing pin actuated by pressure from the propellant charge when ignited to start the time delay fuse. The projectile has a safety pin locking the firing pin in ineffective position and which is withdrawable to arm the projectile. The fuse has a detonator spaced from the firing pin and a heat resistant resilient disc is interposed between the firing pin and detonator and is connected about the periphery to the wall on the side facing the detonator while a passage through the wall equalizes the pressures in the chambers.
