Abstract

203,586. Kerff, G. Nov. 20, 1922. Mandrels.-A composite core for supporting a header a for a water-tube boiler during corrugating, consists of a number of flat plates lying closely next to each other and held together axially by a mandrel c, but freely slidable at right angles to the mandrel. The upper and lower edges of the plates are shaped to correspond to the final shape of the header after corrugating. Depressions d are formed in the sides of the hole for the mandrel, into which a tool may be inserted for withdrawing the plates after corrugating.
