Abstract: A work table in a glass forming unit in apparatus for producing hollow glass articles has an orifice plate which is loosely fitted in a recess of the work table. Therefore, the orifice plate can be removed or mounted on the work table instantly while the orifice plate is firmly secured to the work table during the operation of the work table because the orifice plate expands by the heat of the handled molten glass to be friction-fitted in the recess. The orifice plate is formed of material having a coefficient of thermal expansion equal to, or relatively larger than, that of the work table.

Abstract: A rotatable neck ring assembly for use primarily in an automatic blow molding machine includes an annular bushing and a concentrically arranged series of pivotally mounted foot members which in their closed position cooperate with the bushing to hold a parison during molding of the ware. The feet are spring-biased toward open position and cammed in to closed position when engaged by the upwardly moving parison mold. Cam surfaces on the outer surface of the feet cooperate with corresponding surfaces on a concentrically surrounding sleeve to hold the ring tightly closed on the rim of the parison even after lowering of the parison mold and throughout the blow molding portion of the cycle. The ring is opened following the molding and cooling portions of the cycle by hydraulic pressure acting on a piston which engages the upper surface of the bushing to force the feet to pivot outwardly.

Abstract: A machine for the manufacture of glass articles by blow moulding comprises a plurality of article-forming assemblies mounted in a circular array on a rotatable carousel. Each assembly has a number of operating means which cooperate to shape a gob of molten glass, first by rough-blanking using a plunger, and then by blow-moulding, into the required article. Control of said operating means is effected by a set of primary control members adjustably positioned in fixed locations around the carousel, and a respective set of carousel-mounted secondary control members associated with each assembly. As the carousel rotates, the secondary control members are moved past and influenced by corresponding ones of the primary control members and, as a result, the operating means of each assembly are appropriately controlled to shape the required article.

Abstract: A multi-gob glassware forming machine has a blank station at which parisons are formed from gobs of molten glass in a plurality of blank moulds, an intermediate station at which the parisons are supported after having been transferred from the blank station, and a blow station at which the parisons are blown in blow moulds to the shape of the articles of glassware. The spacing of the supported parisons at the intermediate station is smaller than the spacing of the centers of the blow moulds at the blow station and the machine has transfer means which increase the spacing of the parisons during transfer of the latter from the intermediate station to the blow station.

Abstract: A glassware forming machine has at least three individual side-by-side molds at both the blow and the blank side of the machine, which molds are upwardly open and adapted to be closed by a blowhead or baffle depending upon which side of the machine (blank or blow) that the molds are at, that is for either forming the final article at the blow side or the preliminary parison at the blank side. Three blowheads are disclosed for use at the blow side of a machine, and are retained in a carrier arm for limited vertical movement in order to accommodate variations in height of the tops of the individual molds. Two links extend laterally through slots in the blowhead retainers, and a bellcrank lever interconnects these links to the carrier itself so that upon closing contact made between one of the three blowheads and its associated mold, downward movement of the other two blowheads will occur thereby equalizing the closing forces between all three blowheads and their associated molds.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. Three independently operable transfer means move, respectively, a parison formed in an upright position at the first station to the second station, a further formed parison from the second station to the third station, and an article of glassware from the third station to a takeout position over a deadplate. The operating speed and rate of acceleration of each of the three transfer means is selected independently of the operating speed and rate of acceleration of both the other transfer means to effect its movement in the shortest practicable time compatible with the state of the glass during the movement of that transfer means.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. A parison formed in the first station is transferred to the second station and released there by a first transfer means. A second transfer means which is operated independently of the first transfer means engages the parison at the second station and moves the parison to a third station in which an article of glassware is formed. By adjusting the time of operation of either transfer means relative to the other, the period of time during which the parison reheats may be changed without altering the relative timing of any of the machine functions which together make up the parison-forming cycle or the relative timing of any of the machine functions which together comprise the glassware forming cycle.

Abstract: A glassware forming machine has three operating stations, in the first of which a parison is formed in an inverted position. First transfer means transfers a parison from the first station to a second station where the parison is released by the first transfer means in an upright position. A second transfer means receives the released parison at the second station and supports it for a selected time, after which the second transfer means transfers the parison to a third station, releases it and reverts to a position at the second station for receiving a further parison. A third transfer means operative independently of both the first and second transfer means removes an article of glassware from the third station and supports the glassware for a cooling period beyond the third station.

Abstract: An apparatus for manufacturing glass bottles is disclosed which includes consecutively delivering gobs of molten glass into a blank mold, forming each gob into a parison, transferring the parisons alternately into at least two sets of blow molds, allowing said parisons to reheat, and expanding the parisons in the blow molds. The sets of blow molds recipricate along a substantially vertical path. A first position where the parisons are alternately received by the blow molds and blown containers removed is located on the vertical path. The parisons are expanded and cooled in the blow molds by blowing them out or by applying a vacuum, or a combination of those means at a second position on the vertical path. The apparatus is an improvement to forming sections of the well known Hartford type I.S. machine.

Abstract: A multi-section blow molding machine for the manufacture of hollow glassware has in each section a parison mold for each pair of blow molds. The blow molds are disposed below and on opposite sides of the center of oscillation of a neck ring arm carrying rotatable neck rings and arranged so that the mold or molds on one side are open when those on the other side are closed. The molds and neck ring arm are interconnected to oscillate together in opposite directions between lockable positions 180.degree. apart. The parison mold and associated feed and plunger means are movable in and out of operative position below and above the neck ring arm respectively, and operate in timed relation thereto. The open blow molds are spray cooled during the blowing cycle as well as during oscillation of the neck ring arm between its locked positions. In the closed blow molds, the blowing is continued simultaneously with the spray cooling to further cool the molded articles prior to release to a take-out conveyor.

Abstract: Two sections of a multiple section-type of glass forming machine are disclosed in which each section is comprised of a single parison forming station and two blow molding stations with a pair of transfer arms for alternately transferring and reverting the formed parisons from the parison station to the blow molding stations. A take-out means is provided for each blow molding station to move the blown ware to a dead plate. A sweepout device moves the ware from the cooling dead plate to a conveyor. A common conveyor for all of the forming machine sections is provided for conveying the ware away from the sections which are physically arranged as in-line forming machine sections.

Abstract: Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape.

Abstract: An improved apparatus for the transfer of mold rings in a centrifugal casting process. One type of forming process for the funnel portions of color television picture tube envelopes utilizes a centrifugal casting process for the glass. This process requires a main mold body. An indexing mechanism moves from a station at which the mold ring is deposited on the main mold to a station where the mold ring is removed from the main mold after completion of the casting process. A movable shuttle member is connected to pivotally mounted pairs of support fingers for the mold rings through connecting rods. An external drive motor operates a single actuator at each machine cycle. This single actuator causes the entire shuttle to shift and a mold ring to be deposited at one station and a second mold ring to be simultaneously picked up at another station. Because of the mechanical linkage design, one pair of support fingers always opens while all the others close when the single actuator is operated.

Abstract: An individual section of a Hartford I. S. type glassware forming machine is modified to provide for in-line, or parallel motion, of the split mold halves at both the blank and blow stations. Vertically extending rock shafts move the blank and blow mold holder structures on fixed ways, through toggle links similar to those in a conventional I. S. machine, but the space formerly occupied by the hinge pin at the blow side is made available for the mold structure because the ways are oriented parallel to and slightly below the neck ring hub mechanism. This design provides for an increased mold closing force at the blank side and simplifies the mold holder structure itself whereby the molds can be continually cooled from an internal chamber in the mold holder which is supplied with cooling air through a vertical interface between the movable mold holder structure and the fixed machine frame.
