In a blank mold side of an I.S. glass container forming machine, mold cooling air flows from a fixed source through a supply conduit to a plenum that underlies and oscillates with a mold-carrying arm. Cooling air from the source flows upwardly through the supply conduit and then into a hollow member that has an inlet portion telescopically received in an outlet of the supply conduit. The hollow member, which is capable of oscillating motion in a horizontal plane with respect to the supply conduit, has a horizontallyfacing outlet with an annular part-spherical bearing surface, and an annular part-spherical bearing is positioned in the part-spherical bearing surface for pivoting motion in a vertical plane of the part-spherical bearing with respect to the hollow member. A cooling air inlet tube has an inlet end telescopically received in the part-spherical bearing. The outlet end of the cooling air inlet tube is non-telescopically received in a part- spherical bearing surface of the plenum. In a blow mold side of an LS. glass container forming machine, cooling air flows from a fixed source through a supply conduit to a plenum that underlies and oscillates with a mold-carrying arm without any substantial change in the direction of air flow therethrough. A cooling air inlet tube having an outer element, an inner element telescopically positioned within the outer element and a spring to resiliently bias the inner element and the outer element away from one another is provided to accommodate changes in distance between the source and the plenum that occur because of oscillating motion of the mold-carrying arm. ® KIPO & WIPO 2007
