Abstract

672,487. Moulding-machines. HANSBERG, F. June 22, 1950, No. 15645/50. Class 83 (i). A core-moulding machine comprises a container for the sand, loam, &c. with one or more outlets and a conduit for compressed air connected to the container through a large, quickacting valve and if desired a smaller adjustable throttling valve. The container 3 may have a perforated metal liner 4 and a replaceable nozzle 7 around which is arranged a head 8 to engage the core box having exhaust openings 9 covered with gauze 10. The valve 13 has a cone 13<1> to direct air so that some enters the container 3 through the liner 4. It is operated pneumatically by a spring-returned piston. The throttling valve 14 may be moved by a hand wheel 17. The core box is placed on a table 19 which is raised by a pneumatic piston 21. The container 3 is arranged to swing on the conpressed air supply 1, shown as a reservoir. Packing 22 avoids loss of compressed air.
