Abstract
151,831. Evans, W. E., (Europaischer Verband der Flaschenfabriken Ges.). Oct. 16, 1919. Blowing; delivering molten metal.- Relates to improvements in automatic bottle-blowing machines of the Owens type such as described in Specifications 13026/03, 14184/05, and 29251/12. The objects of the invention are to give additional support to the blank and to eliminate marks in the finished article caused by the cut-off knife. According to the invention, the finishing-mould R is mounted on a carriage O which can be raised and lowered along a slide P by pneumatic gear M. The mould bottom Q can also be raised and lowered pneumatically and independently of the mould R. As soon as the knife I, Fig. 6, has cut off the excess of metal, the mould bottom Q is raised so as to close the bottom of the parison mould D, Fig. 7, and is kept in the raised position so as to support the parison until the blowing has been completed in the finishing-mould, which is opened and closed pneumatically.
