Abstract

988,750. Joint-making packing. F. HANSBERG. March 12, 1963 [March 23, 1962], No. 9800/63. Heading F2B. [Also in Division B3] In a foundry mould &c. blowing machine the joint between the feed slide 28 and the sand container 2 is sealed by a joint 22 inflatable by compressed air. The joint 22 is clamped by annular fillets having inclined surfaces which exert a wedging action, and the material of the joint is elastically deformable. Specifications 763,036, 988,748 and 988,749 are referred to.
