Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
A method for packaging a dry cell in a cylindrical metal jacket comprising: positioning an insulating film across one end of said jacket to completely cover said end; positioning an insulating disc, of a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said end; ramming a cylindrical insulating sleeve into said jacket, through said end, in a manner such that said insulating disc and said insulating film are pushed ahead of said sleeve through the bore of said jacket; and inserting said dry cell within said insulating sleeve.
Claim 2
Independent Claim
98 words
A method for packaging a dry cell in a cylindrical metal jacket comprising: positioning an insulating film across one end of said jacket to completely cover said end; positioning an insulating disc, of a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said end; ramming a cylindrical insulating sleeve into said jacket, through said end, in a manner such that said insulating disc and said insulating film are pushed ahead of said sleeve through the bore of said jacket; and inserting said dry cell within said insulating sleeve.
Claim 3
Independent Claim
171 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a cylindrical metal jacket with the opposite end of said jacket having an inwardly disposed lip; b. positioning an insulating disc having a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said jacket; c. pushing a cylindrical insulating sleeve having an inwardly disposed lip at one end into said cylindrical jacket in a manner such that the lip end of the sleeve rams the insulating disc and the insulating film through the bore of the jacket to the bottom of the jacket until the disc and insulating film come to rest on the lip of the jacket; and d. inserting a dry cell having an inwardly disposed lip at one end, within said insulating sleeve in such a manner that the lip end of the dry cell comes to rest on the lip of the insulating sleeve.
Claim 4
Independent Claim
171 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a cylindrical metal jacket with the opposite end of said jacket having an inwardly disposed lip; b. positioning an insulating disc having a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said jacket; c. pushing a cylindrical insulating sleeve having an inwardly disposed lip at one end into said cylindrical jacket in a manner such that the lip end of the sleeve rams the insulating disc and the insulating film through the bore of the jacket to the bottom of the jacket until the disc and insulating film come to rest on the lip of the jacket; and d. inserting a dry cell having an inwardly disposed lip at one end, within said insulating sleeve in such a manner that the lip end of the dry cell comes to rest on the lip of the insulating sleeve.
Claim 5
Dependent Claim
49 words
The method of claim 2 wherein the following step is added: e. crimping the end of the metal jacket and the end of the insulating sleeve over the end of the dry cell in a manner such that the outer metal jacket is completely insulated from the dry cell.
Claim 6
Dependent Claim
94 words
The method of claim 2 wherein the following steps are added: e. positioning a false bottom within said insulating sleeve in such a manner that it rests on top of the dry cell; and f. crimping the end of the metal jacket and the end of the insulating sleeve over said false bottom in a manner such that said false bottom is maintained in electrical contact with said dry cell and electrically insulated from said metal jacket, and in such a manner that the outer metal jacket is completely insulated from the dry cell.
Claim 7
Independent Claim
110 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a metal jackEt to completely cover said end; b. positioning an insulating disc, of a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said end; c. inserting a dry cell into an insulating sleeve; and d. ramming said insulating sleeve containing said dry cell into the metal jacket, through said end, in a manner such that said insulating disc and said insulating film are pushed ahead of said sleeve through the bore of said metal jacket.
Claim 8
Independent Claim
110 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a metal jackEt to completely cover said end; b. positioning an insulating disc, of a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said end; c. inserting a dry cell into an insulating sleeve; and d. ramming said insulating sleeve containing said dry cell into the metal jacket, through said end, in a manner such that said insulating disc and said insulating film are pushed ahead of said sleeve through the bore of said metal jacket.
Claim 9
Independent Claim
176 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a cylindrical metal jacket with the opposite end of said jacket having an inwardly disposed lip; b. positioning an insulating disc having a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said jacket; c. inserting a dry cell having an inwardly disposed lip at one end into a cylindrical insulating sleeve having an inwardly disposed lip at one of its ends in such a manner that the lip end of the dry cell comes to rest on the lip of the insulating sleeve within said sleeve; and d. pushing said cylindrical insulating sleeve containing the dry cell into said cylindrical jacket in a manner such that it rams the insulating disc and the insulating film through the bore of the jacket to the bottom of the jacket until the disc and insulating film come to rest on the lip of the jacket.
Claim 10
Independent Claim
176 words
A method for packaging a dry cell in a cylindrical metal jacket comprising the steps: a. positioning an insulating film across one end of a cylindrical metal jacket with the opposite end of said jacket having an inwardly disposed lip; b. positioning an insulating disc having a diameter smaller than the diameter of said jacket, on said insulating film in register with the periphery of said jacket; c. inserting a dry cell having an inwardly disposed lip at one end into a cylindrical insulating sleeve having an inwardly disposed lip at one of its ends in such a manner that the lip end of the dry cell comes to rest on the lip of the insulating sleeve within said sleeve; and d. pushing said cylindrical insulating sleeve containing the dry cell into said cylindrical jacket in a manner such that it rams the insulating disc and the insulating film through the bore of the jacket to the bottom of the jacket until the disc and insulating film come to rest on the lip of the jacket.
Claim 11
Dependent Claim
49 words
The method of claim 6 wherein the following step is added: e. crimping the end of the metal jacket and the end of the insulating sleeve over the end of the dry cell in a manner such that the outer metal jacket is completely insulated from the dry cell.
Claim 12
Dependent Claim
94 words
The method of claim 6 wherein the following steps are added: e. positioning a false bottom within said insulating sleeve in such a manner that it rests on top of the dry cell; and f. crimping the end of the metal jacket and the end of the insulating sleeve over said false bottom in a manner such that said false bottom is maintained in electrical contact with said dry cell and electrically insulated from said metal jacket, and in such a manner that the outer metal jacket is completely insulated from the dry cell.
