In a blank mold side of an I.S. glass container forming machine, mold coolin g 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 sour ce 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 horizontallyfacin g 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 respe ct to the hollow member. A cooling air inlet tube has an inlet end telescopical ly received in the part-spherical bearing. The outlet end of the cooling air inlet tube is non-telescopically received in a part-spherical bearing surfac e 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 substanti al change in the direction of air flow therethrough. A cooling air inlet tube having an outerelement, an inner element telescopically positioned within th e outer element and a spring to resiliently bias the inner element and the out er element away from one another is provided to accommodate changes in distance between the source and the plenum that occur because of oscillating motion o f the mold-carrying arm.
