Abstract

334,960. United States Cast Iron Pipe & Foundry Co., (Assignees of Langenberg, F. C.). Dec. 29, 1928, [Convention date]. Addition to 334,634. Drawings to Specification. Metal-working apparatus.-In the manufacture of a steel pipe mould, or reconditioning a used mould, as described in the parent Specification, the interior of the mould is finally smoothfinished. A used pipe mould is bored out, either before or after contraction.
