Abstract: A valve block for glassware forming machines is rendered faster and more accurate by substituting, for the pilot air system, a plurality of solenoids directly coupled with the cartridge valves which handle the operational air, the major part of the bodies of said solenoids being arranged across the main operational air feed manifold to be cooled by the air passing therethrough, a closed chamber around the upwardly projecting ends of said solenoid valves, means for passing cooling air through said chamber, a plate for closing the lower ends of said valve chambers, and a plurality of manually actuatable push buttons in said lower plate to permit manual actuation of said cartridge valves. In order to facilitate removal of the cartridge valves for maintenance purposes, said valves are modified by removing the wider portion of their bodies and providing a section in the valve chamber of smaller diameter to engage the end plunger portion of the valve member.

Abstract: The present invention relates to a lehr loader apparatus generally of the type shown in U.S. Pat. No. 4,067,434. The improvement here lies in a mechanical coupling between the prime mover and the pusher bar cam which permits the total time of the forward pushing stroke to be greater than the time of the return stroke for any given speed of operation of the apparatus.

Abstract: A lehr for heat treating glass articles is assembled from a series of modules to define an elongated insulated tunnel. A belt conveyor extends throughout the tunnel for moving articles from one end to the other. Duct work connection between the tunnel and the ambient air and associated heating and blower means establish heating, tempering and cooling zones respectively within the lehr in the direction of conveyor movement. Temperature sensors adjacent both flights of the conveyor are linked with a control panel to permit establishment of any desired temperature curves.

Abstract: A parison mold and baffle system for an automatic molding machine of the I-S type including a two piece split parison mold with an integral funnel thereon. The funnel portion terminates upwardly in an annular opening with walls of outwardly tapering cross section. A combined blow-down and baffle head has blow-down nozzles, a downwardly facing annular groove which is snugly received on the walls of the funnel in both the blow-down and mold closing baffle positions. Blow-down starts from the initial engagement of the blow-down and baffle head on the funnel and continues until said mold end is completely closed by the baffle.

Abstract: A valve block for glassware forming machines is rendered faster and more accurate by substituting, for the pilot air valve system, a plurality of solenoids directly coupled with the cartridge valves, the coupling between said solenoids and said valves comprising a lost motion mechanical memory which, on reception of one pulse by the solenoid, pushes the cartridge valve and forces it to remain open, until reception of the next pulse by said solenoid, when it releases the cartridge valve to be closed; and a compensating spring, which is stronger than the force necessary to open said valves but weaker than the maximum force exerted by said solenoid, between said lost motion mechanical memory and said cartridge valve.

Abstract: A parison mold and baffle system for an automatic molding machine of I-S type includes a two piece split parison mold with an integral funnel. A combined blow-down and baffle member cooperates with the mold in a first position to perform the blow-down function and then in a second position acts as the bottle bottom end of the mold during the blow-back final shaping of the parison.

Abstract: An improved glassware article forming machine employing a hollow arm, one end of which is rigidly carried at the upper end of the vertical hollow shaft, the other end of each hollow arm being provided with a glassware article receiving chuck, and including mechanism for imparting vertical movement to the hollow shaft and associated arm, and mechanism for imparting oscillatory movement to the hollow shaft associated arm, and mechanism for supplying an adjustable amount of air through the hollow shaft and associated hollow arm for circulation into the chuck and about the hot glassware article received from a blow mold to provide an air cushion on which the glassware article will ride while providing cooling for said hot glassware article throughout its vertical and oscillatory movement to a takeout position.

Abstract: Article handling apparatus for use in conjunction with a glassware forming machine is effective to remove finished ware from a dead plate where it has been placed to cool and transfer it to a moving conveyor. An electronic control synchronizes the movements of the apparatus with the cycle of the forming machine and deposits the ware on the moving conveyor with a component of velocity in the direction of the conveyor movement which effects smooth transfer to the conveyor irrespective of variations in conveyor speed.

Abstract: A mold gauging device and a method for gauging a mold is disclosed wherien a false mold having vertically adjustable gauges therein is positioned between a mold hinge in substitution for a mold to be set therein and with other alignment means placed on the false mold measurements are made of the mold to be set therein to its other cooperating mechanisms, which mechanisms are then adjusted to their proper positions.

Abstract: In a glass molding machine, for example, of the type known in the industry as I.S. machines, an apparatus for shearing molten glass into gobs as the glass issues from a feeder includes mechanisms for independently adjusting both the horizontal and vertical position of the shears with respect to the feeder nozzles, as well as the distance between the two halves of the shear blades and the length and time duration of the cutting stroke. All adjustments are possible without shutting down the entire forming operation and can be effected merely by supplying energy to adjusting motors.

Abstract: A method of blow molding hollow ware in a paste mold machine includes positioning a blow nozzle in spaced non-sealed relation to the neck ring. During the blowing portion of the molding cycle, air is continuously flowed into and out of the ware so as to simultaneously cool and shape the ware.

Abstract: A feeder chute for glass molding machines has a cross section defined by an even number, preferably four of equal length sides. Each side may be either plane or curved convexly inwardly in a horizontal plane.
