  • Time fuse
    Patent number: 4004520
    Abstract: A time fuse for a non-spinning projectile has a pivoted catch connecting a fuse setting member to a setting disc whereby rotation of the member rotates the disc to wind a clockwork spring. A plunger is locked in a housing in the setting member by a movable ball or spring held by a spring-urged inertia block. When the fuse is set, the plunger acts on the catch to disconnect the disc and member upon displacement of the inertia block in response to axial acceleration of the projectile in a piece of ordnance.
