Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
The method of forming an elongated pin type connector comprising the steps of, extruding a disc of resilient and flexible metal into a tubular body having a closed end, which tubular body has a maximum outside diameter of about 0.037 inch, bulging outwardly an elongated section of said tubular body to a wall thickness of about 0.003 inch, heat treating the tubular body to uniform hardness to obtain consistant spring action, cutting a plurality of elongated slots having a uniform width of less than 0.010 inch through the wall of said elongated section of said tubular body along the longitudinal length thereof and at circumferentially spaced locations by subjecting the metal to spark erosion.
Claim 2
Independent Claim
114 words
The method of forming an elongated pin type connector comprising the steps of, extruding a disc of resilient and flexible metal into a tubular body having a closed end, which tubular body has a maximum outside diameter of about 0.037 inch, bulging outwardly an elongated section of said tubular body to a wall thickness of about 0.003 inch, heat treating the tubular body to uniform hardness to obtain consistant spring action, cutting a plurality of elongated slots having a uniform width of less than 0.010 inch through the wall of said elongated section of said tubular body along the longitudinal length thereof and at circumferentially spaced locations by subjecting the metal to spark erosion.
Claim 3
Independent Claim
90 words
A method of forming an elongated pin type connector, comprising the steps of: forming a disk of resilient metal into a tubular body having a closed end, the body having a maximum outside diameter of about 0.037 inch and a wall thickness of about 0.003 inch; and cutting a plurality of elongated slots having a uniform width of less than 0.010 inch through the wall of said elongated section of said tubular body along the longitudinal length thereof and at circumferentially spaced locations by subjecting the metal to spark erosion.
Claim 4
Independent Claim
90 words
A method of forming an elongated pin type connector, comprising the steps of: forming a disk of resilient metal into a tubular body having a closed end, the body having a maximum outside diameter of about 0.037 inch and a wall thickness of about 0.003 inch; and cutting a plurality of elongated slots having a uniform width of less than 0.010 inch through the wall of said elongated section of said tubular body along the longitudinal length thereof and at circumferentially spaced locations by subjecting the metal to spark erosion.
Claim 5
Dependent Claim
27 words
The method defined in claim 2 and further comprising the step of heat treating the tubular body to obtain consistent spring action prior to cutting the slots.
