Patent ID: 7694534

Claim:
A mechanism for delivering a cooling fluid to the interior of a hot glass bottle after it has been formed in a blow mold of an I.S. Machine comprising a guide arm including a plurality of blow heads; a corresponding number of vertical cooling tubes operatively associated with said blow heads; a vertical post, said guide arm being operatively coupled to said vertical post; a cooling tube arm assembly being operatively coupled to said vertical post; a motor for displacing said cooling tube arm assembly independently of said guide arm between a first up position and a second down position; wherein said second down position of said cooling tube arm assembly positions said vertical cooling tubes within the bottle; a source of pressurized air; conduit means for connecting said source of pressurized air to said vertical cooling tubes; pressure regulator means in said conduit means for defining the pressure of the air delivered to said cooling tubes; and a control for operating said motor to displace said vertical cooling tubes from said up position to said down position, wherein when the cooling tubes are in the up position the glass bottle is formed with a first high pressure air and when the cooling tubes are in the down position the glass bottle is cooled with a second lower pressure air, and for conjointly operating said pressure regulator to decrease the pressure of the air supplied to said vertical cooling tubes from the first higher pressure to the second lower pressure as said vertical cooling tubes are displaced from said up position to said down position.
