Abstract
181,434. Hailwood, E. A. March 5, 1921. Delivering m o l t e n metal; pressing.-A device for pressing articles from glass comprises a mould, a cup for measuring the quantity of glass to be pressed, and a device for giving the article an auxiliary or secondary squeeze after it has been formed in the mould by the plunger of the press. In the construction shown in Fig. 1, a measuring-cup C having a removable base C<1> is mounted above the mould. The cup C is of such dimensions, or is provided with indicating- marks C<2>, that the correct quantity of glass to form the article can be gauged. After filling, the base C' can be drawn away to allow the glass to fall into the mould. The plunger P moves down through the cup to press the glass and this plunger is provided with a sleeve P<1>, which, either by itself or by acting on a flange P<x> in the mould, brings an additional pressure on the article after formation to size it and to squeeze out bubbles. In a modification, instead of having a removable bottom, the cup may be supported on trunnions and tilted to pour its contents into the mould. In other modifications, one cup may serve several moulds, or there may be a series of cups mounted on a wheel to empty their contents into moulds as they are brought into the desired position.
