  • Patent number: 4777879
    Abstract: A fuse for an explosive shell comprises a body having a longitudinal axis, a hood unit fitting over the body and movable along the body vertical axis between a first position and a second position, and a parachute linked to the hood unit for pulling the hood unit from its first position to its second position when the explosive shell is released. A slide catch is housed in the body and is moveable in a direction perpendicular to the body perpendicular axis from an unprimed to a primed position. A primary detonator is housed in the slide catch. The primary detonator is out of alignment with the main charge of the explosive shell when the slide catch is in its unprimed position, and is in alignment with the main charge of the explosive shell when the slide catch is in its primed position. A safety catch holds the slide catch in its unprimed position until it is released by inertial forces acting on the fuze. A firing pin detonates the primary detonator.

  • Patent number: 4726297
    Abstract: A projectile has a housing with a forward end a rearward portion. A pusher disc in the rear portion of the housing supports columns of submunitions which are urged forwardly by a forward force exerting compression spring toward bell means mounted in the forward end of the housing. A plurality of rods each have a shear portion adjacent their lower ends and a forward end connected to the bell and a lower end fixed connected to the rear end of the projectile. The forward force exerting spring urges submunitions forwardly against a front plate which is prevented from forward movement by engagement with the bell. Explosive means shear the rods and separate the forward portion of the housing from the tail portion and outward force exerting springs shift the forwardmost submunition outwardly after separation of the forward housing portion from the tail portion so that the forward force exerting spring moves the remaining submunitions forwardly for subsequent discharge from the projectile.
