Plunger base module for a plunger mechanism of an I.S. machine

A plunger base module for use in the blank station of a section of an I.S. machine with a number of vertically extending plunger cylinders up to a selected number with each cylinder having a bottom surface and including a set of service conduits including plunger up, plunger down, and counterblow/vacuum or cooling, with each of the service conduits in a plunger cylinder having a selectively located inlet port communicating with the bottom surface of the plunger cylinder comprising

• a permanent plunger distribution base having a top surface and including said selected number of sets of service conduits, each set including plunger up, plunger down, and counterblow/vacuum or cooling conduits for one plunger cylinder, each plunger distribution base service conduit having an outlet port communicating with said top surface,
• a removable transition plate having a bottom surface for engaging said top surface of said plunger distribution base and a top surface, said transition plate having a number, up to said selected number and equal to the number of plunger cylinders, of sets of service conduits, each set including a plunger up, plunger down, and counterblow/vacuum or cooling conduit for one of the plunger cylinders,
• each of said sets of service conduits in said transition plate having inlet ports in the transition plate bottom surface for communicating with corresponding outlet ports of one of said sets of service conduits in said plunger distribution base and having outlet ports in the transition plate top surface selectively located to communicate with corresponding inlet ports of one of the plunger cylinders positioned on the transition plate.
