Abstract: An improved glass pressing machine which captures exhausting cooling gas to reduce noise in the vicinity of the machine. A glass press for making television face plates includes a cooling station where large quantities of a gas, such as air, are blown on a newly formed article to remove residual heat. Escape of this air creates a noise problem in the area of the machine. The tube which introduces the gas is substantially enclosed by a shroud. The gas, as it completes its cooling function, is conducted from an exhaust pipe in the shroud to a vent stack which delivers the gas to a location remote from the machine. The spent cooling gas is therefore not exhausted at the machine location to create a noise problem.

Abstract: In a conjunction with a glassware press-molding machine, an arrangement of Bernoulli nozzles is employed to remove the articles from the mold, complete the forming of the articles, cool them, heat treat them and transfer them to a conveyor. The cooling and heat treating is effected by air from the nozzle combined with an airflow directed onto the underside of the articles while supported by the Bernoulli nozzles.

Abstract: A furnace for heat treating glass sheet material including a circular enclosure having top, bottom and side walls of refractory material. Inlet and outlet openings are formed in the side walls. The side walls have an outer insulating layer and an inner layer of material having a low coefficient of thermal expansion, the inner layer having spaced end portions projecting beyond the outer layers and the periphery of the side walls to define said inlet and outlet openings. Each opening is controlled by doors, and each door includes an elongated support bar with a plurality of blocks of refractory material supported on the bar in end-to-end relationship. The blocks are adjustably secured to the bar to accommodate irregularities in the openings.
