<p>A glassware forming machine blowhead arm assembly (12) includes a one-piece blowhead arm body (26) having at least one longitudinal air passage (36) and a plurality of lateral air passages (30-34) connected to the longitudinal passage. A blowhead chuck (44) is removably received in a first end of each lateral passage and a cap (60) is threaded into the second end of each lateral passage spaced from the associated blowhead chuck. A spring (66) is captured in compression between each cap and an associated blowhead chuck biasing the blowhead chuck in a direction out of the lateral passage and away from the cap. In an exemplary embodiment of the disclosure adapted for use in conjunction with so-called isolated finish cooling blowheads, there are first and second longitudinal air passages (28, 36) extending through the blowhead arm body separately from each other, and separate air inputs (18, 22) in the body respectively coupled to the first and second longitudinal passages. Each lateral air passage is separately connected to the longitudinal air passages, and the blowhead chucks have separate air passages for feeding blow air and finish cooling air to a blowhead (54) mounted in the chuck.</p> |
