Abstract
379,229. Glassware manufacture. OWENS-ILLINOIS GLASS CO., Nicholas Building, Toledo, Ohio, U.S.A. Feb. 23, 1932, No. 5377. Convention date, Oct. 26, 1931. [Class 56.] A method of forming a hollow glass article comprises forming a parison by introducing separate streams of glass simultaneously through separate openings into a mould cavity and causing said streams to merge and fill the cavity. The invention is described with reference to a suction-gathering machine of the Owens type having a rotary carriage with dipping frames carrying parison moulds to which air and vacuum can be supplied. Each parison mould 13 comprises separable sections each formed with a cavity 27, and having a lug 29 at the centre of the base. These lugs, in the closed position of the mould, form a bridge across the cavity, leaving openings 28. The upper surface 29<1> of the bridge is convex, while the ridge of this surface extending lengthwise of the bridge from one mould wall to the other is concave. In gathering, glass enters by both openings 28, the two streams merging to fill the mould. A shearing knife severs the charge and forms a mould closure while the initial blowing is performed. The suspended parison is supported by a mould bottom having a convex upper surface and is blown in a finishing mould.
