Abstract

809,175. Making valves. CAMERON IRON WORKS Inc. Dec. 17, 1956 [March 21, 1956], No. 38405/56. Drawings to Specification. Class 83 (2). [Also in Group XXIX] The method of fabricating a liner for a plug valve (see Group XXIX), comprises bonding a thin sheet of gasket material to each side of a thin sheet of metal with the sheets extended flat, blanking out the liner from the bonded sheets, and bending the blanked piece into a frusto-conical shape.
