摘要:
An apparatus for manufacturing strengthened glass containers, and more particularly the construction and operation of a cooling tube nozzle in an apparatus for thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are rapidly thermally strengthened in a cooling station in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers, with the cooling tube nozzles being used to cool the inner surfaces of the glass containers.

摘要:
A change system for changing an orifice plate that is registered with an orifice ring is provided. The orifice plate change system includes a guide arrangement, a plurality of orifice plates, and an actuator. The guide arrangement has a charging plate region and an operating plate region. Each orifice plate is configured to be slidably carried by the guide arrangement between the charging plate region and the operating plate region in which the orifice thereof is registered with the orifice ring orifice. A first orifice plate has a first orifice and a second orifice plate has a second orifice that is different than the first orifice such that a stream of molten glass that passes through the second is different than a stream of molten glass passing through the first orifice. The actuator translates the orifice plates from the charging plate region to the operating plate region.

A heat shield for the refractory tube in a molten glass feeder has an annular metal shell with semi-circular insulating segments stacked therein. The shell is made in half sections to permit easy removal and the segments are provided in sets with relieved areas to accommodate the reciprocating refractory plungers.

A molten glass feeder includes a feeder bowl and a rotating refractory tube. Molten glass is discharged through openings in an orifice plate which are controlled by vertically displaceable needles. To reduce heat loss through the refractory tube, a heat shield is provided which is made up of two mirror imaged parts. Each part has a semicylindrical pan having a lip at the bottom for supporting a semi-circular support plate. Located on this plate is an insulation retainer which has a semi-circular base and a vertical wall at its diameter. This wall forms an insulation receiving bin with the pan.

摘要:
A ware transfer mechanism is disclosed which includes equally spaced pockets which have a fixed rear wall and a side wall advanceable from a retracted position to an advanced position as the pockets are displaced along an arcuate path across the transfer plate overlapping a first conveyor and transverse cross conveyor. Containers will be displaced by the side wall to locate the container in line with the containers on the cross conveyor.
