Abstract

205,083. Etablissements A. Sisson- Lehmann. Oct. 3, 1922, [Convention date]. Moulding-machines.-Sand is packed in foundry moulds I by means of a current of air. The sand is delivered through a vibrating sieve K to a tube D suspended by a universal joint G so that it can be moved about by handles H. Air from a fan A is introduced into the tube by a nozzle C so arranged that it draws in additional air from the upper end of the tube. The Specification as open to inspection under Sect. (91) (3) (a) states also that the machine may be movable about the foundry along a straight or circular path. This subject-mater does not appear in the Specification as accepted.
