ABSTRACT:
An inertia fuse for use in spinning projectiles includes a firing pin and a spring for pushing the firing pin into a detonator. The spring force is isolated from the firing pin during flight by means of centrifugally-responsive bodies which are interposed between the spring and a sharp locking edge of a housing of the fuse. An inertia sleeve is slidable coaxially relative to the firing pin and has a beveled forward edge disposed behind the bodies and arranged to contact the bodies and wedge same inwardly away from the locking edge in response to impact, in order to release the spring sooner than would otherwise occur. The locking edge imposes minimal frictional forces against unlocking movement of the bodies.
