  • Publication number: 20070295032
    Abstract: A burner nozzle for depositing soot on a glassware mold includes an inner member and an outer member surrounding at least a downstream portion of the inner member. A first gas passage extends through the inner member for delivering a fuel gas to at least a single outlet port from the inner member. A second gas passage extends between the inner and outer members in an annulus surrounding the first passage for delivering a second gas through the annulus to at least one second outlet port. The first and second outlet ports preferably form an annular composite array in which the first and second outlet ports alternate with each other. The second plurality of ports preferably comprise slots having long dimensions radial to the annular array. The first plurality of outlet ports preferably are circular.

  • Publication number: 20070277558
    Abstract: A burner for depositing carbon soot on a glassware mold includes a burner nozzle having an annular array of individual gas outlet ports, a fuel passage within the nozzle connected to a first plurality of the outlet ports and an oxidant passage in the nozzle connected to a second plurality of the outlet ports. The first plurality of outlet ports individually alternate with the second plurality of outlet ports around the annular array such that the array presents alternate fuel and oxidant outlet ports around the array. A spark electrode is disposed on the burner nozzle within the annular array of outlet ports for igniting fuel and oxidant emerging from the outlet ports. The spark electrode preferably is in the form of an elongated ignition electrode rod telescopically surrounded by an insulator and centered on the burner nozzle within the annular array of outlet ports, and a ground electrode telescopically surrounding the insulator.

  • Publication number: 20060179884
    Abstract: In a blank mold side of an I.S. glass container forming machine, mold cooling air flows from a fixed source through a supply conduit to a plenum that underlies and oscillates with a mold-carrying arm. Cooling air from the source flows upwardly through the supply conduit and then into a hollow member that has an inlet portion telescopically received in an outlet of the supply conduit. The hollow member, which is capable of oscillating motion in a horizontal plane with respect to the supply conduit, has a horizontally-facing outlet with an annular part-spherical bearing surface, and an annular part-spherical bearing is positioned in the part-spherical bearing surface for pivoting motion in a vertical plane of the part-spherical bearing with respect to the hollow member. A cooling air inlet tube has an inlet end telescopically received in the part-spherical bearing. The outlet end of the cooling air inlet tube is non-telescopically received in a part-spherical bearing surface of the plenum.

  • Publication number: 20060144088
    Abstract: A surface mixing burner (16) is positioned in alignment with a mold of a glass container forming machine of the I.S. type to produce a supply of soot to lubricate an inner surface of the mold, the soot being produced by combustion of a rich, combustible supply of a fuel and an oxidant. The supply of fuel and oxidant is intermittently ignited by a sparking device (54) that is positioned within a sooting head (10), and an ignition coil (56) is positioned within the sooting head to deliver a high voltage pulse to the sparking device by the inductive discharge method. The ignition coil is positioned sufficiently close to the sparking device, and preferably in direct contact therewith, to avoid interference with the proper operation of an electronic control system for the I.S. machine. A remotely-positioned power supply (62) is provided to energize the ignition coil, the power supply providing power to the ignition coil at a relatively low voltage, for example, 12-24 volts d.c.

  • Publication number: 20060081007
    Abstract: Vertically aligned first (30) and second (32) combined blowhead and takeout mechanisms are provided to sequentially blow glass parisons (P) into containers (C) in a mold set (22) and to transfer blown containers to a deadplate (40) of a glass containing forming machine (20). Each of the combined mechanisms is pivotally suspended about an axis A from a carrier arm (36) that is pivotally attached to an end of an oscillating arm (38), an opposed end of which is pivoted about an axis (B). The axis (B) of each combined blowhead and takeout mechanism is periodically raised and lowered to permit the other combined blowhead and takeout mechanism to oscillate therebeneath, to thereby permit overlapping cycles between the blowhead and takeout mechanisms. Each blowhead and takeout mechanism is provided with a chuck or tong assembly (54) to engage or release each container by its finish (F).

  • Publication number: 20050264154
    Abstract: A spark electrode assembly has an elongate electrode with an inner insulator arranged for operable attachment to a support structure. The inner insulator surrounds the electrode with one end of the electrode positioned adjacent a ground element across a spark gap and another end of the electrode extending relative to the support structure for attachment to a source of electrical power. An outer insulator is spaced radially outwardly from the inner insulator and surrounds the inner insulator generally adjacent the end of the electrode adjacent the ground element. The inner and outer insulators cooperate to inhibit the formation of a continuous lubrication layer thereon, thereby establishing an area generally free from the lubrication layer between the end of the electrode adjacent the ground element and the support structure.

  • Publication number: 20050005647
    Abstract: An invert assembly for an individual section glassware forming machine includes an invert base that is oscillated about an axis between angularly spaced apart first and second positions, a double ended ball screw positioned co-axially with the axis and having spaced apart oppositely threaded portions, first and second nuts each threadably engaging one of the oppositely threaded portions of the ball screw so that the nuts reciprocate toward and away from each other in response to rotation of the ball screw, and first and second neck ring arms respectively engaging the first and second nuts so that the neck ring arms reciprocate toward and away from each other along the axis with the first and second nuts. Preferably, the invert base is oscillated about the axis by a first reversible electric motor, and the ball screw is driven for rotation in opposed directions by a second reversible electric motor to move the nuts and neck ring arms toward and away from each other along the axis.
