Abstract
419,425. Moulding-machines. STAHN, A., 4, Hohenzollernstrasse, Hanover, Germany. June 25, 1934, No. 18704. Convention date, June 28, 1933. [Class 83 (i).] Sand is projected into a mould or core box from containers 1 under the action of compressed air admitted through flexible tubes, or, alternatively, through flexibly mounted tubes 7, the tubes moving over the surface of the sand under the action of the compressed air, so preventing the formation of channels or craters in the sand. The flexible tubes may be of rubber or metal-spiral tubing, and the joint 8 may be a ball-joint or a short length of flexible tubing.
