Abstract
650,506. Core-making machines; moulding processes; moulding-machines. WOOD, D. H., and WILSON, C. H. July 1, 1948, No. 17683. Drawings to Specification. [Class 83 (i)] Comprises apparatus for making sand cores as described in Specification 650,507 and claims making a core by applying air pressure to sand in a container to discharge the sand through at least one valved passage leading into a core box mainly in the direction of its length. Each box is closed except for air vents. The air pressure may be 70 to 120 lbs. per square inch, and the core-box vents may be arranged as in the above Specification.
