Abstract

414,053. Casting-machines., SMETHURST, H., 147, Victoria Road, Fallowfield, BANCROFT, F. E., 19, Delaine Road, Withington, both in Manchester, BURROWS, G., Lynton, Fownhope Avenue, Sale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 19, 1933, No. 19321/34. Divided on 413,698. Drawings to Specification. [Class 83 (i).] Metal-pouring ; moulds.-A vacuum chamber 1 containing an electrically heated crucible and a mould as described in Specification 413,698 is characterized in that the means for permitting the metal to flow from the crucible to the mould is operated by a member which passes through a hole in the chamber wall and is connected thereto by a flexible vacuum tight member. The mould has a cooling jacket and is mounted on a jacketed and vacuumsealed door of the chamber. All the parts may be constructed and operated as described in Specification 413,698. Specification 407,503, [Group XXVIII], also is referred to.
