Abstract
Abstract An article of manufacture is disclosed having a first part constructed or powdered metal and having a lip which extends outwardly from one end of the first part. A second part, for example a steel stamping, has a first side, a second side and an opening extending between its sides. The opening is dimensioned so that, with the second part positioned on the end of the first part, the lip extends through the opening and outwardly from the second or outer side of the second part. The first and second parts are then mechanically secured together by deforming the lip so that a portion of lip overlies and entraps an edge portion of the second part between the deformed lip and the end of the first part.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
An article of manufacture comprising a first part constructed of powdered metal, said first part having a lip which extends outwardly from one end of said first part, a second part having a first side, a second side and an opening extending between said sides of said second part, said opening being dimensioned so that, with said first side of said second part in abutment with said end of said first part, said lip extends through said opening and outwardly from said second side of said second part, said first and second parts being mechanically secured together by deforming said lip so that a portion of said lip overlies and entraps an edge portion of said second part between said lip portion and said end of said first part.
