Abstract
A plunger assembly is provided wherein the precise centering of the perforated section of the cooling tube within a plunger of an I.S. type glass forming machine is achieved by securing the cooling tube to the plunger. The base of the plunger has a recess which wedgingly receives a plurality of equally spaced wedge elements secured to an annular collar fixed to the cooling tube. The wedge elements are sufficiently tall that they will extend beyond the plunger base, thereby defining exit openings through which plunger cooling air can be discharged.
