There is provided a system of an individual section machine (IS) having a blow side with a mold and a blow head, and a blank side, the system includes a P-Switch valve in fluid communication with an EPVB of the IS machine and with the P-Switch valve configured to control a valve pilot air supply to a predetermined pilot valve. When the P-Switch valve is activated, the blow side mold is set to an OPEN position and the associated blow head is set to an UP position. With the P-Switch valve of the system activated, the blow side machinery cannot be overridden from the blank side of the IS machine.

P-switch pilot operating air supply controller

A pneumatic machine control unit for an I.S. machine having at least one machine section for processing a gob of molten glass into a selected bottle. The section is supplied by a plurality of pneumatic lines at different pressures. A pneumatic supply input line supplies a manifold which is connected to a plurality of output lines. An electronically settable pressure regulating device is situated in each output line and a control is provided for setting the electronically settable pressure regulating devices either in response to operator inputs or from retrieved pressures from a database.

Pneumatic machine control unit for an I.S. machine

A plunger base module for a selected number of vertically extending cylindrical plunger canisters each 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 canister having a selectively located inlet port communicating with the bottom surface of the plunger canister. The plunger base module includes a permanent plunger distribution base having a top surface and a plurality of sets of service conduits, each set including plunger up, plunger down, and counterblow/vacuum or cooling. Each plunger distribution base service conduit has an outlet port communicating with the top surface. A removable transition plate has a bottom surface for engaging the top surface of the plunger distribution base and a top surface. The transition plate has a number, equal to the number of plunger canisters, of sets of service conduits, each set including plunger up, plunger down, and counterblow/vacuum or cooling. Each of the service conduits in the transition plate has an inlet port in the transition plate bottom surface for communicating with a corresponding outlet port in the plunger distribution base and has an outlet port in the transition plate top surface selectively located to communicate with a corresponding inlet port in a plunger canister positioned on the transition plate. The plunger distribution base also includes a valve for selectively blocking the flow of the services to the transition plate.

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

An I.S. Machine for making glass bottles, having a plurality of sections, each having a blank station for forming a parison. Each section has a section frame having a top surface, and a plunger mechanism including at least one plunger canister having a lower cylinder and an upper flange. A horizontal mounting plate having a top surface and vertical openings for receiving the lower cylinder of each of the plunger canisters is fixedly secured on the top surface of the section frame. The section frame top surface has vertical openings for receiving the lower cylinders of each of the plunger canisters and the flange of the plunger mechanism is secured to the top surface of the mounting plate.

I. S. machine

A plunger mechanism comprising a vertically extending cylindrical plunger canister having a bottom surface and including a plurality of service air conduits with each conduit having an inlet port communicating with the bottom surface. A plunger distribution plate below said plunger canister having a top surface and including a corresponding plurality of service air conduits which are to be connected to the plunger canister service air conduits with each plunger distribution plate conduit having an outlet port communicating with the top surface. At least one outlet port of the plurality of service air conduits in the plunger distribution plate which are to be connected to the plunger canister service air conduits being axially offset from the corresponding inlet port of the plunger canister. A transition plate intermediate the plunger canister and the plunger distribution plate having a bottom surface for engaging the top surface of the plunger distribution plate and a top surface.
