Abstract

998,666. Core-boxes; making core-box vents. HILLSDALE TOOL & MANUFACTURING CO. Dec. 3, 1963 [Jan. 3, 1963], No. 47790/63. Headings B3A and B3F. A core-box vent has an annular body portion 32 and a head portion 28 with an annular venting gap 34 therebetween. The vent is formed from a sheet material blank, Fig. 4, and the head portion is located after bending with respect to the body portion by a tongue or tongues 44. In a modification, Figs. 8, 9, the tongues are omitted, the vent being more suitable for lower core-box filling pressures.
