Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
A method of forming an annular slot in a longitudinally splined annular member to receive a snap-type retaining ring therein; said method comprising lancing the root section of each spline of said splined member along two spaced lines and further comprising the step of displacing the material between said lanced portions radially away from said root section.
Claim 2
Independent Claim
57 words
A method of forming an annular slot in a longitudinally splined annular member to receive a snap-type retaining ring therein; said method comprising lancing the root section of each spline of said splined member along two spaced lines and further comprising the step of displacing the material between said lanced portions radially away from said root section.
Claim 3
Dependent Claim
25 words
The method as defined in claim 1 and in which the material between said lanced portions is displaced radially outwardly away from said root section.
Claim 4
Dependent Claim
25 words
The method as defined in claim 1 and in which the material between said lanced portions is displaced radially inwardly away from said root section.
Claim 5
Independent Claim
52 words
A method of forming an annular slot in a longitudinally splined annular sheet metal member; said method comprising lancing the root section of each spline of said splined member along two spaced lines and further comprising the step of displacing the material between said lanced portions radially away from said root section.
Claim 6
Independent Claim
52 words
A method of forming an annular slot in a longitudinally splined annular sheet metal member; said method comprising lancing the root section of each spline of said splined member along two spaced lines and further comprising the step of displacing the material between said lanced portions radially away from said root section.
Claim 7
Dependent Claim
22 words
The method defined in claim 4 wherein said material between said lanced portions is displaced radially outwardly away from said root section.
Claim 8
Dependent Claim
22 words
