An underwater gun barrel seal for preventing fluid from entering a gun barrel comprising:
- a muzzle seal means joined to a muzzle of said gun barrel, said muzzle seal means allowing discharge from said gun barrel;
- a sealing plate joined in a movable relation to said barrel and having at least one firing aperture therein, said sealing plate having at least two positions in relationship to said gun barrel, a first position wherein communication through said gun barrel muzzle is prevented by said sealing plate and a second position wherein communication through said gun barrel muzzle is allowed through said firing aperture, said muzzle seal means being positioned against said sealing plate;
- and
- an actuating means joined between said sealing plate and said gun barrel for moving said sealing plate between said first position and said second position.
An underwater gun barrel seal for preventing fluid from entering a multi-barrel gun comprising:
- a muzzle seal means mounted on said multi-barrel gun having a face seal means which fits over the muzzle of each said gun barrel, a shaft seal means constructed and arranged on the inside of said face seal means and engaging said muzzle, and a spring means engaging said face seal means, said muzzle seal means allowing discharge from at least one said gun barrel;
- a sealing plate joined to said multi-barrel gun barrels to allow relative movement between said sealing plate and said multi-barrel gun barrels, said sealing plate having at least two positions in relationship to said gun barrels, a first position wherein communication through said gun barrel muzzles is prevented by said sealing plate and a second position wherein communication through at least one said gun barrel muzzle is allowed, said muzzle seal means being positioned against said sealing plate;
- and
- an actuating means joined between said sealing plate and said multi-barrel gun barrels and providing relative motion between said sealing plate and said gun barrels from said first position to said second position.
