Abstract

601,691. Making poppet valves. EATON MANUFACTURING CO. May 31, 1945, No. 13673. Convention date, April 22, 1944. [Class 83 (ii)] A method. of making a hollow poppet valve comprises forming the hollow stem 14 and head 12 as shown inserting the coolant 22, welding or otherwise securing a closure member 20 over the open end of the stem, forging the enlarged upper end of the stem to form a permanent, integral seal and finally cutting and shaping the closed end.
