Abstract
438,394. Moulding-machines. ZIMMERMANN, G., 19, Lindemannstrasse, Dusseldorf, Germany. Nov. 22, 1934, No. 33604. Convention date, Dec. 7, 1933. [Class 83 (i)] [See also Group V] A pneumatic mould-pressing and shockless jarring machine has a valveless jarring device arranged within the pressing piston 3 so that, during pressing, the jarring device can be used to hammer on the mould table 7. This has a plunger 6 working in a cylinder 4, both being provided with ports and passages 11 ... 20, so that, when air is admitted at 11, the plunger is reciprocated and, as the cylinder 4 is carried by a spring 5 adapted to support the parts 4, 6, 7 and the filled mould, the shock of the table 7 on buffers 8 is not transmitted to the foundation. If air is also admitted to a pipe 2, the piston 3 rises and presses the mould 23, false flask 24, and pattern 22 against the fixed head H while the cylinder 4 reciprocates and strikes blows on the table 7 from below.
