Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
In a clevis comprising a U-member and a shank provided with ends respectively proximal and distal to said U-member, the improvement which comprises: (a) said shank and said U-member being formed from separate pieces; (b) said U-member provided with a hole in the bight thereof; said shank being tubular and formed of a deformable material; (c) said proximal end of said shank having an annular shoulder formed thereon which abuts against said U-member, said shank being positioned in said hole and the terminal portion of said proximal end extending through and beyond said bight, and (d) an outwardly extending flange formed by said terminal portion, said flange extending retrorsely into engagement with the periphery of said hole on the inner surface of said bight whereby said U-member is sandwiched between said flange and said annular shoulder to prevent both distal and proximal movement of said shank.
Claim 2
Dependent Claim
146 words
In a clevis comprising a U-member and a shank provided with ends respectively proximal and distal to said U-member, the improvement which comprises: (a) said shank and said U-member being formed from separate pieces; (b) said U-member provided with a hole in the bight thereof; said shank being tubular and formed of a deformable material; (c) said proximal end of said shank having an annular shoulder formed thereon which abuts against said U-member, said shank being positioned in said hole and the terminal portion of said proximal end extending through and beyond said bight, and (d) an outwardly extending flange formed by said terminal portion, said flange extending retrorsely into engagement with the periphery of said hole on the inner surface of said bight whereby said U-member is sandwiched between said flange and said annular shoulder to prevent both distal and proximal movement of said shank.
