Gun bore rust inhibiting method and apparatus

Claim 1

Apparatus for inhibiting rust in the bore of a barrel of a gun having a muzzle and a breech, said apparatus comprising: first generally cylindrically shaped hollow capsule means with one end open and containing a desiccant therein and having a passage means in said one end, said first capsule means having a slightly tapered outer surface toward said one end, the outer surface being of a size so that said first capsule means can be inserted into the muzzle of the gun in substantially sealing engagement, with the passage means in communication with the bore of the gun; second generally cylindrically shaped hollow capsule means with one end open and containing desiccant therein and having passage means in said one end, the passage means of said second capsule means being located axially inward from said one end thereof so that a cylindrical side wall extends beyond said passage means, the inside surface of said side wall being slightly smaller than the outer surface of said one end of said first capsule means, said second capsule means having a slightly tapered outer surface toward said one end, the outer surface being of a size so that said second capsule means can be inserted into the breech of the gun in substantially sealing engagement, with the passage means in communication with the bore of the gun; the first and second capsule means being adapted to be interfitted with the outer surface of said one end of said first capsule means engaging the inside surface of said one end of said second capsule means so that said respective passage means only communicates with each other and thereby substantially prevent depletion of said desiccant.
