Abstract

996,740. Moulding-machines. OSBORN MANUFACTURING CO. Jan. 28, 1963 [Feb. 26, 1962], No. 3465/63. Heading B3F. In a mould and core blowing machine, pressure air is supplied internally of the body of sand in the reservoir 5 through means having 26 a large number of small apertures. The air is supplied via a valve 18 which may be connected to exhaust to relieve excess pressure in the reservoir after blowing. Imperforate sleeves may be fitted over the perforated conduit 26 to mask selected apertures.
