Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
A method of forming a clevis comprising a U-member and a shank with ends proximal and distal to said U-member, said shank having an annular shoulder spaced from its proximal end, said method comprising the steps of: (a) forming a hole in a metal bar; (b) inserting said proximal end of said shank through said hole so that said shoulder abuts against one side of the metal bar; (c) rolling said proximal end outwardly to form a flange pressing against the surface of said bar whereby a portion of said bar is sandwiched between said shoulder and said flange; and (d) thereafter forming said bar into said U-member.
Claim 2
Independent Claim
