Abstract

See full text

A revolver-type firearm has a barrel-cylinder gap created between its barrel and a rotatable cartridge cylinder. The cartridge cylinder has a plurality of cartridge chambers each with corresponding counterbore retaining a translatable shuttle. When a cartridge is fired, the shuttle expands and translates forward toward the breech-end of the barrel and seals the barrel-cylinder gap to prevent the escape of gases, flames, and residue through the barrel-cylinder gap. When pressure drops as the cartridge projectile exits the barrel, the shuttle contracts. The barrel-cylinder gap opens upon rotation of the cartridge cylinder as the shuttle translates away from the breech-end of the barrel. The shuttle has a thin cylindrical body, a beveled front end, and a conical central bore and is manufactured from a hard elastic metal or metal alloy such as one comprising titanium.
