Abstract: The disclosure includes a process and an apparatus for delivering a gob of molten glass into a blank mold. The apparatus includes a loading funnel holder that defines at least one opening, and a split loading funnel rotatably carried by the funnel holder. The split loading funnel includes two or more individual funnel segments that together provide an outlet of the funnel having an exit plane, each of the individual funnel segments having a lower portion that includes a concave interior guide surface. The two or more individual funnel segments are coupled together so that the interior guide surfaces of the individual funnel segments cooperate to define a guide passage extending along a longitudinal axis and terminating at the outlet.

Abstract: A multiple orifice glass feed system for use with a glass forehearth including a plurality of closely spaced plungers, each of which is individually supported independently of the other. Each plunger includes a servo controlled linear actuator and an arm extending between each plunger and its respective servo-motor. Each servo-motor has an axis parallel to the axis of the plungers. An air spring is associated with each plunger for balancing the weight of each plunger and its respective arm. The center lines of the plungers lie generally in a plane. The arms have the major portions thereof generally parallel and closely spaced. A feedback system is provided to monitor the position of each individual needle independently of the other at all times and make corrections to the actual position of the needle if desired.

Abstract: A method for delivering a coated glass stream having a first inner layer and a second outer layer wherein the method includes providing a vertical orifice, delivering molten glass from a first source through the orifice, providing a gap about the orifice intermediate its upper and lower ends, delivering glass from a second source about the gap such that the glass from the second source flows through the gap to provide an outer layer about the glass from the first source as it flows through the orifice, and controlling the size and shape of the gap parallel to the flow and the size of the gap perpendicular to the flow such that the gap provides sufficient flow resistance and the gap is of sufficient size and shape to prevent clogging. The method includes the step of providing passages for the flow of the glass from the second source and controlling the size and shape of the passages such that the passages are sufficiently large to minimize flow resistance therein and to provide sufficient pressure to force the glass through the gap and provide less resistance than the metering gap. The method also includes providing a plurality of orifices, each having a gap, delivering glass from the first source through each of the orifices, delivering glass from the second source to the gaps and controlling the size and shapes of such gaps.

Abstract: A multiple glass feed system for use with a glass forehearth including a plurality of closely spaced plungers, each of which is individually adjusted independently of the other. The upper end of each plunger is oval in cross section and the lower end is round. The oval portions of the plungers are each supported in an individual clamping mechanism having a chuck housing, a curved liner plate within the housing, and a cap screw which extends between the housing and liner plate to engage the upper end of the plunges and clamp the plunger in the housing to arrange the plungers in side by side relation to each other with the long axis of each oval portion parallel to the long axis of the adjacent plungers.

Abstract: A glass article such as a sham bottom tumbler with a decorative air bubble encapsulated in its base is produced on existing automatic glass-forming machines by injecting a bubble of air into a charge of molten glass in the gob-feeder section of a glass furnace as the charge is being formed into a gob. This is accomplished by mounting an air supply pipe in the gob-feeder orifice. Preferably, the outlet end of the pipe extends radially to the center of the orifice. Puffs of compressed air are supplied in synchronism with the feeder plunger cycle so an air bubble is formed in the lower end of the gob, and the gob is then formed by normal procedures into a finished article.
