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: A magnetic drive for a metallic conveyor belt is provided by a driving wheel having permanent magnets disposed in the outer periphery thereof, the magnets protruding radially outwardly so that they act as cleats for driving the belt in addition to supplying a magnetic shear force for driving the belt.

Abstract: A system for distributing successively formed groups of glass gobs from a feeder bowl to the several individual sections of a Hartford I.S. type glassware forming machine includes a single scoop for each gob in the group, and mechanism for rotating the scoops between successive positions wherein each is aligned with a chute associated with a particular mold cavity in each machine section. A "double-gob" installation is described and the two scoops have associated annular spur gears which are driven in unison by a reciprocable rack gear through a predetermined schedule of angular displacements to successively align the two scoops with several sets of paired chutes according to a particular order and to then repeat this schedule. A cam follower connected to the rack gear causes programmed movement thereof in response to rotation of a cam having lobes of predetermined height to produce the predetermined schedule of angular displacements of the scoops.
