  • Method of setting small objects in malleable sheet material and apparatus for carrying out the method
    Patent number: 6253432
    Abstract: A method and apparatus for setting small gem stones in malleable material including precious metals such as gold sheets, so as to form lockets, pendants and other jewelry. Sheet material thinner than used in a completely hand-set operation is pressed to form a recess for the gem, and projections around the recess. The stone is deposited in the recess and the assembly is pressed in a jig, causing the projections to become deformed and form claws over the gem stone edge, setting it in the sheet.
