Abstract: An apparatus for hydraulically cushioning the motion of reciprocating means is provided by first hydraulic cushioning means which is adapted to be contacted by the reciprocating means near the end of its stroke in the direction of the first hydraulic cushioning means, second hydraulic cushioning means adapted to be contacted by the reciprocating means near the end of its stroke in the direction of the second hydraulic cushioning means, and means for adjusting the position at which the reciprocating means contacts at least one of said first and second hydraulic cushioning means.

Abstract: An individual section of a multiple section glassware forming machine is shown wherein each such section preferably includes three stations performing separate and sequential operations in forming articles of glassware. Each such section may be adapted for "single gob" or "multiple gob" use whereby each station in the section performs its operation in forming either a single article of glassware or multiple articles at the same time. The section shown is adapted for "double gob" operation. Its first station is utilized in forming (by overhead pressing plungers) two parisons in upright parison molds. Its second station is utilized to further form the parisons either in intermediate blow molds or by suspending the parisons for a re-heat. Its third station is utilized to blow the parisons into the final shape of the glassware article being made.

Abstract: The individual section of a Hartford I. S. type machine is modified to permit forming the parisons in an upright orientation, and also for transferring the upright parisons from the blank to the blow side of the section without disturbing this upright orientation. The pressing plungers at the blank station are mounted for movement toward and away from the upwardly open blank mold cavities, and each blank mold cavity is defined in part by partible neck ring molds, in part by a lower solid blank or body mold, and finally by intermediate partible mold sections which engage the upper neck ring molds and also the lower body mold. These intermediate mold sections at the blank side of the machine are mounted on the existing blank mold holder arms.

Abstract: Apparatus and transport system for production of pressed articles from plastic material, e.g., molten glass. A series of molds is routed on non-linked carriages over an endless course defined by a plurality of cooperating conveyors disposed over the course. The course comprises a charging section, a molding section, a solidification section, and a discharge section. Means can be provided for varying the speed of the carriages by operation of the conveyors in accordance with the working time at the respective sections.

Abstract: A machine for forming hollow articles of vitreous material includes at least one forming station provided with at least one forming means and for each forming means a neck ring means carrying a parison and including a pair of neck ring halves and a guide ring coaxially carried by the neck ring halves and rotatable relative thereto. The guide ring which engages the parison at its mouth is rotated to thereby impart to the parison a rotary motion relative to the remainder of its forming means which may comprise a split mold to thereby avoid formation of seams or fins on the finished hollow article and to improve the surface quality thereof.

Abstract: The neck ring arms of a Hartford I. S. type glassware forming machine section are adapted to be oscillated between a blank and a blow station, and also to move toward and away from one another in order to cooperate with one another and with a blank mold at the blank side of the machine, and to release a partially formed parison at the blow side of such a machine. In a triple gob configuration, where three such neck ring molds are provided, cartridges are disclosed for conveniently mounting the six neck ring mold segments for quick assembly with the associated neck ring arms. The cartridges can be quickly removed with a minimum downtime to the machine section, and the neck ring mold segments bench-assembled in the cartridge at the leisure of the machine operator.
