Abstract: Plural article transfer mechanisms are operated in timed sequence by an electronic control synchronized to a main drive shaft. Each article transfer mechanism transfers articles from a dead plate to a moving conveyor. An extensible-retractable pusher arm engages, moves and releases the articles between 90.degree. positions under control of a fluid motor mounted on a turntable. Operation of the fluid motor is based on rotary alignment of a pair of turntable ports with a pair of fluid supply channels in a turntable drive body. The turntable is stepped in rotary increments between 90.degree. positions by an electric stepping motor. The angular speed profile of the pusher arm between the 90.degree. positions is governed by a programmed electronic control, including a PROM, which drives the stepping motor. An adjustable finger clip assembly is snap-fitted on the pusher arm and provided with a handle for ease of replacement.

Abstract: A neck ring mechanism for transferring a blank or parison from a blank mold section to a blow mold section of an I.S. glass forming machine includes a rock shaft and a pair of spaced cylinders reciprocable in opposition directions on the shaft. The rock shaft is provided with a plurality of longitudinal grooves, and a like plurality of followers are arranged in the grooves so as to contact at least one side wall of each groove. The followers are supported on each cylinder. One or more piston rings are seated in associated annular grooves in the rock shaft so as to preclude air leakage.

Abstract: A quadruple gob glass feeder and cooperating shear mechanism are disclosed. The shear mechanism has two arms reciprocal toward and away from each other. Each arm has four blades arranged in mating pairs to cooperate with each other for cutting four streams of glass.

Abstract: A shear mechanism adapted to be attached to a glass feeder for cutting a glass stream into gobs includes a housing supporting a pair of blade arms. At least one blade is connected to each arm. The blades are adapted to be in overlapping relationship in one position of the arms. A motor is supported by the housing and has its output mechanically connected to a pair of shafts for oscillating the arms in unison in opposite directions between open and closed positions.

Abstract: A pusher is disclosed for transferring plural glass containers onto a conveyor. The pusher includes a finger for each glass container. Each finger is separately retractable after its container has been transferred onto a conveyor so as to prevent a collision between the second container and the finger for the first container.

Abstract: An arm which may support a baffle or blowhead is adapted at one end for clamping to a vertical shaft. First and second holder units are supported by the arm between its ends. Each unit has a holder open at its bottom and into which a baffle or blowhead may be inserted from below. A spring biased latch is provided for each unit and adapted to prevent relative rotation between the holder and its associated baffle or blowhead. A manifold in the arm communicates with each unit by exposed conduits.

Abstract: A profile control for a shear mechanism of a glass processing machine eliminates cams, gears, etc. otherwise required to oscillate the shear mechanism arms in unison in opposite directions between open and closed positions. The profile is the angular position time curve of the arms as they open and close over a predetermined angular displacement. The profile is controlled by adjustable oscillators and programmable memory (PROM) which determine the commands to a reversible dc motor drive. The control synchronizes the movement of the arms in proper phase relationship with respect to the feeder mechanism of the glass processing machine.

Abstract: First and second arms for holding a blank mold are pivotable about a shaft between an open position and a closed position by means of a motor. A motor operated cam cooperates with rollers on the arms to apply a clamping force to prevent premature movement of the arms toward an open position.

Abstract: The molten glass feeding bowl has two parallel sides with a third side being generally perpendicular thereto. Electrodes for heating glass within the bowl extend through aligned holes in the side walls of the refractory bowl and metal housing. The bowl can accommodate electrodes along its parallel side walls and along a front wall depending upon the operative position of the shear mechanism which may extend along the center line of the bowl or to either side of the center line.

Abstract: A valve block assembly for use in glassware forming machines is disclosed. The valve block has at least two rows of valve stations arranged parallel to one another. An air supply manifold and an air exhaust manifold communicates with each row of valve stations. A cartridge valve is disposed at each of the valve stations for controlling the air flow through a respective valve station. An outlet conduit, having a needle valve disposed within it, forms a flow path away from the cartridge valve. A check valve is also disposed within at least one of said outlet conduits. All of the valves are mounted in a vertical front face of the valve block.
