Firearm sealing device

Claim 2

A firearm sealing device comprising: a. a sleeve means insertable in one end of a firearm barrel and having an end opening presented to the interior of the barrel, b. cord means adapted to extend through the sleeve means, its opening and the barrel to the other end of the barrel, c. ferrule means insertable in said other end, said ferrule means having a portion sized to preclude its passage into the barrel, d. first retainer means engageable with said cord means inside of said sleeve means and second retainer means engageable with said cord means in the vicinity of said ferrule means, and e. means imparting a tensile force on said cord means for the retainer means to compress the sleeve and ferrule means into respectively opposite ends of the barrel to seal it.

Claim 3

The invention set forth in claim 1 including: a. spring means adapted to fit coaxially with and interiorly of said sleeve means for imparting the said tensile force on said cord means, said cord means restraining its associated retainer means against said spring means to compress it, b. said ferrule means having a longitudinal slot for passing the same over said cord means in the vicinity of the retainer means at said other end, c. said spring means acting through said cord means and retainer means to urge said sleeve means and said ferrule means toward each other.

Claim 4

The invention set forth in claim 1 wherein: a. said ferrule means has a flared external end and an internal seating recess for said retainer means, b. the said retainer means having a ball shape.

Claim 5

The invention set forth in claim 1 including: a. coil spring means coaxial with the interior of said sleeve means for reacting against said retainer means and imparting said tensile force to said cord means, b. plunger means having one end adapted to extend coaxially with and from said sleeve means and having flange means at its opposite end cooperating with said coil spring means.

Claim 6

The invention set forth in claim 1 wherein: a. said cord means is elastic and adapted to impart the said tensile force.

Claim 7

The invention set forth in claim 1 including: a. plunger means adapted to move inside of said sleeve means and to extend therefrom into the barrel of a firearm, b. spring means disposed in said plunger means for exerting a tensile force on said cord means by way of said retainer means, c. said cord means passing axially through said plunger means.

Claim 8

A firearm sealing device comprising: a. a flexible elastic cord adapted to pass through a firearm barrel and to be extended by and tensed by the application of a force at a place on the cord beyond an end of the barrel, b. first retainer means engageable with the elastic cord at one end of the barrel, said retainer means preventing withdrawal of the cord from the barrel when the cord is extended by application of a tensile force thereon, c. second retainer means engageable with said elastic cord at the other end of the barrel, and d. a ferrule adapted to be interposed between said second retainer means and an end of the barrel when the cord is extended elastically, said ferrule means having a longitudinal slot for passing said cord through it and having a flared end larger than the bore of the barrel to prevent withdrawal of the second retainer means into the barrel when the cord is released and in tension under its elastic influence, e. said second retainer means having a curved surface which is adapted to seat in said ferrule, whereby a curved key may be engaged with said curved surface to retract said second retainer means for removal of said ferrule means.

Claim 9

A firearm sealing device comprising: a. a flexible elastic cord adapted to pass through a firearm barrel and to be extended by and tensed by the application of a force at a place on the cord beyond an end of the barrel, b. first retainer means engageable with the elastic cord at one end of the barrel, said retainer means preventing withdrawal of the cord from the barrel when the cord is extended by application of a tensile force thereon, c. second retainer means engageable with said elastic cord at the other end of the barrel, and d. a ferrule adapted to be interposed between said second retainer means and an end of the barrel when the cord is extended elastically, said ferrule means having a longitudinal slot for passing said cord through it and having a flared end larger than the bore of the barrel to prevent withdrawal of the second retainer means into the barrel when the cord is released and in tension under its elastic influence, e. said second retainer means having a curved surface which is adapted to seat in said ferrule, whereby a curved key may be engaged with said curved surface to retract said second retainer means for removal of said ferrule means.
