Abstract

180,200. Smith, R. H. May 12, 1921. Extrusion machines.-Tubular articles of clay such as chimney pots are manufactured by expanding a tubular length of clay over a tapering core within a mould. Clay is forced through an annular shaping-space g provided between a fixed core f and a fixed die e, which is attached to the upper end of a mould a. Initially a core d is moved up into the mould a, its upper tapering part bedding against the lower end of the fixed core, and as the clay is fed the core is lowered until the clay tube reaches the lower end of the mould. The core d is then raised and the clay tube is thereby pressed into contact with the inner surface of the mould a, displacing the initially thickened parts of the wall to compensate for the increased diameter. The article so obtained is removed, after lowering the core d, by opening the mould a which is in two parts a<2>, a<3> hinged to a support a<6> at a<4>, a<5>.
