Abstract

566,339. Moulding-machines. JONES & ATTWOOD, Ltd., and FOLKES, H. L. Aug. 2, 1944, No. 13812/43. [Class 83 (i)] A mould is produced by placing sand a<1> loosely in a box a and forcing a plunger c<2>, with portions c<1> and h<1> of different cross-section, through the sand to compress it and form the cavity required. Local enlargements n, Fig. 2, are formed by applying axial pressure to rubber or other resilient rings i by means of a sleeve m.
