Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 151 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; and inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, whereby when said plug is secured to said one chain end and the other end of said chain introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
Claim 2
Dependent Claim 151 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; and inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, whereby when said plug is secured to said one chain end and the other end of said chain introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
Claim 3
Dependent Claim 151 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; and inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, whereby when said plug is secured to said one chain end and the other end of said chain introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
Claim 4
Dependent Claim 151 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; and inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, whereby when said plug is secured to said one chain end and the other end of said chain introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
Claim 5
Dependent Claim 45 words
A safety device in accordance with claim 1 wherein said combination lock includes a rotatably positionable tumbler ring, said ring including a groove adapted to be aligned with said path by manipulation of said ring to allow said chain to be inserted through said lock.
Claim 6
Dependent Claim 25 words
A safety device in accordance with claim 2 wherein realignment of said groove out of said path prevents withdrawal of said chain form said lock.
Claim 7
Dependent Claim 33 words
A safety device in accordance with claim 2 and further characterized by means for retaining said tumbler ring at a plurality of positions wherein said groove is out of alignment with said path.
Claim 8
Dependent Claim 255 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; an inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than the diameter of said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, said combination lock including at least one rotatably positionable tumbler ring, compressed spring and sphere, said ring including a groove adapted to be aligned with said path by manipulation of said ring to allow said chain to be inserted through said lock, said ring also including a plurality of peripheral notches for retaining said tumbler ring at a corresponding plurality of positions wherein said groove is out of alignment with said path, said sphere adapted to be urged by expansion of said spring to occupy any one of said notches to temporarily retain said ring with respect to said path, whereby when said plug is secured to said one chain end and the other end of said chain end introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
Claim 9
Dependent Claim 255 words
A safety device for firearms having a barrel with a breech and including a cartridge head recess, comprising in combination: a flexible bead chain having a length in excess of the length of said barrel; an inwardly tapering plug adapted to be removably secured at its smaller end to one end of said chain, a portion of said plug having a diameter greater than the diameter of said cartridge head recess; and a tubular combination lock adapted to be releasably secured to said bead chain at a location intermediate the ends thereof by insertion of said chain through a tortuous path in said lock, said combination lock including at least one rotatably positionable tumbler ring, compressed spring and sphere, said ring including a groove adapted to be aligned with said path by manipulation of said ring to allow said chain to be inserted through said lock, said ring also including a plurality of peripheral notches for retaining said tumbler ring at a corresponding plurality of positions wherein said groove is out of alignment with said path, said sphere adapted to be urged by expansion of said spring to occupy any one of said notches to temporarily retain said ring with respect to said path, whereby when said plug is secured to said one chain end and the other end of said chain end introduced through said barrel, said lock can be secured to said chain at a location corresponding to the length of said barrel to prevent introduction of a cartridge into said head recess.
