Abstract: A piston rod of a piston and cylinder device has an axial bore through which a fixed non-ferromagnetic monitoring member extends, and a detection insert of ferromagnetic materially extending generally axially of the monitoring member. A magnetic circuit is created through a base of the cylinder, a sidewall, the piston and the detection insert, and movement of the piston is detected by a Hall sensor which detects a change of flux in the magnetic circuit.

Abstract: A trough system for the delivery of a gob of molten glass from a gob distributor to a parison mould cavity in a glassware forming machine comprises a trough assembly comprising an upwardly facing inclined trough which is arranged to receive a gob from a scoop of the gob distributor and a downwardly facing deflector which deflects a gob which has travelled down the trough into a vertical path to fall into the parison mould cavity. The deflector and the trough are mounted on a hanger which is supported in a frame member of the machine by a universal joint adjustable about three perpendicular axes. Consequently adjustment of the position of the deflector may be made without causing misalignment of the deflector and the trough.

Abstract: An inspection machine for inspecting the outer surface of a vertically standing container comprising a transparent convey for conveying a vertically standing container through an inspection location. The support conveyor includes a diffuser plate located to be beneath a conveyed container at the inspection location. A beam of collimated light is directed vertically downwardly towards the diffuser plate, and a two-dimensional camera axially views the bottom of the container above the diffuser plate, and the image is processed to evaluate the circumference of the container.

Abstract: A ware transfer mechanism is disclosed which includes equally spaced pockets which have a fixed rear wall and a side wall advanceable from a retracted position to an advanced position as the pockets are displaced along an arcuate path across the transfer plate overlapping a first conveyor and transverse cross conveyor. Containers will be displaced by the side wall to locate the container in line with the containers on the cross conveyor.

Abstract: A parallel movement mould mechanism for use in a glassware forming machine comprises mould mounted for movement on horizontal shafts and means (90, 102) for moving the mould supports comprising a cage assembly in which a piston and cylinder device linked to the mould supports is mounted, the cage assembly being mounted for adjustable pivotal movement with respect to shafts so that adjustment of the position of the cage assembly adjusts the position of the centre line of moulds supported on the mould supports.

Abstract: A take out mechanism for a glassware forming machine comprises a parallel linkage for effecting movement of the takeout tongs. To enable adjustment of the position of the takeout tongs, the position of one of the fixed pivots of the parallel linkage may be adjusted.

Abstract: An I.S. machine is made up of a plurality of independent individual sections for receiving gobs of molten glass and for forming the gobs into glass containers. A gob distributor delivers gobs to the sections. The controller of these sections and the gob distributor are synchronized by means for generating a once per cut signal, a divide by N circuit where N is the number of sections which are to have gobs distributed to them, means for defining N, means for applying N to the divide by N circuit, means for supplying the once per cut signal to the divide by N circuit, and means for distributing the output signal of the divide by N circuit to each of the section and gob distributor controllers.

Abstract: Mechanism for moving an operative member such as a blowhead funnel or baffle in a glassware forming machine comprises a piston rod on which the operative member may be mounted and two piston heads on the rod which may be operated independently of each other, one to cause axial movement of the rod and the other to cause rotation of the rod.

Abstract: An inspection machine for inspecting the profile of a vertically standing glass bottle comprising a conveyor for horizontally displacing a vertically standing glass container through an inspection location, a pair of diffused light sources located behind the conveyor for directing beams of light horizontally at a container located at the inspection location, the beams being sufficiently large so that the light beams will pass around the entire profile of a container located at the inspection station, a mirror pair located in front of the conveyor for receiving each of the light beams and redirecting the beam rearwardly, a reflecting prism having a pair of angularly related reflecting surfaces, a two-dimensional camera having an imaging surface, a pair of mirrors for receiving the beams redirected from each of the mirror pairs and redirecting the received beams to reflect off a corresponding one of the prism reflecting surfaces onto a corresponding half of the imaging surface, means for evaluating the profile

Abstract: A parallel movement mould mechanism for use in a glassware forming machine comprises mould supports mounted for movement on horizontal shafts and means for moving the mould supports comprising a cage assembly in which a piston and cylinder device linked to the mould supports is mounted, the cage assembly being mounted for adjustable pivotal (22) movement with respect to shafts so that adjustment of the position of the cage assembly adjusts the position of the center line of moulds (18) supported on the mould supports.

Abstract: A shear mechanism has opposed shear assemblies mounted for reciprocation on a pair of parallel guide rails. Each shear assembly has a removable portion which supports the shears with top accessible fasteners so that these portions can be removed when the shear assemblies are fully advanced. A stop mechanism locks the shear assemblies at their fully advanced positions.

Abstract: A shear mechanism has a shear assembly with shear assembly that can be quickly changed. The shear assembly supports a vertically displacable shear which is operated via a drive system which is connected to the shear mechanism frame. With the release of top fasteners which secure the shear assembly to the guide rail support and the release of a top accessible support bearing the shear assembly can be lifted out of the frame since the shear drive system and shear assembly are vertically separable.

Abstract: A shear mechanism for shearing discrete gobs from at least one runner of molten glass has a shear assembly which is displacable back and forth along a pair of guide rails. The assembly has at least one shear supported on an arm which has a bearing at one side which is operatively associated with one of the guide rails. The support bearing has a lower bearing surface which engages the bottom of the guide rail and an upper bearing surface which supports the top surface and the lower bearing surface can be displaced away from the guide rail by operating a release which is located on the top of the bearing.

Abstract: Shears are supported for reciprocating displacement within an open frame so that they can be conjointly displaced from retracted positions to advanced overlapping positions where a runner of molten glass will be severed. A pair of covers close the open frame except for the central portion where the runners pass through. A pipe having a plurality of holes is secured to the front edge of the covers so that coolant can be directed downwardly and inwardly against the reciprocating shears.

Abstract: A shear mechanism having at least one shear. Each shear has an associated drop guide which can be displaced relative to the shear. The drop guide is secured in position from the front and when release, it can be pulled forwardly and separated from its support for replacement or repair.

Abstract: A push out device for a glass container making machine has a series of pusher fingers mounted on a pusher head arranged for the conventional extended and retracted movement and rotation about a vertical axis. The pusher fingers are mounted in a support plate of the pusher head so that the spacing between a base of the pusher head and the support plate may readily be adjusted.
