Abstract

420,424. Moulding-machines. ZIMMERMANN, G., 19, Lindemannstrasse, D³sseldorf, Germany. July 16, 1934, No. 20755. Convention date, July 20, 1933. Addition to 332,347, [Class 83 (i)]. [Class 83 (i)] The support for a counter-pressure plate 20 of a moulding-machine as described in the parent Specification comprises a telescopic tubular member filled with an adjustable volume of liquid. The plate stem 47 screws into a plunger 46 of a cylinder 45 which can slide in a cylinder 36 attached to the turnover frame. Liquid in a reservoir 37 can flow freely through a non-return valve 40 into the cylinders 36, 45, a spring - closed valve 41 being opened by hand to admit air, but cannot return and so serves to hold the plate 20 during moulding. After invertion spring-closed valves 42, 43 are opened by hand to allow liquid to flow back to the reservoir and air to escape. Movement of the plate 20 may be limited by guide rods 48, 49 with a stop nut or pin 51.
