    • A glass bending and tempering apparatus (10) is disclosed as including a first platen (14) for receiving a heated glass sheet (12) to be bent. The first platen (14) is deformable and includes an actuator (16) for deforming platen (14) from a planar shape to a bent shape. A second platen (22) is mounted above lower platen (14) for bending and quenching glass sheet (12) therebetween the platens. A template (24) is located on the other side of the second platen (22) away from glass sheet (12). Second platen (22) is pressed against template (24) as first platen (14) is deformed from the planar shape to the bent shape to bend the heated glass sheet thereagainst second platen (22), the second platen (22) conforming to template (24). Quenching gas is supplied by both platens (14,22) through quench openings (18) that move with the platens (14,22) to temper the bent glass sheet between the platens.

    • A roll drive mechanism (14) for a horizontal roller conveyor (12) of glass sheet processing equipment (10) has particular utility with a heating furnace (18) of a glass sheet tempering system. First and second continuous drive loops (22,24) of the drive mechanism extend along the conveyor and are alternately engageable in a driving relationship with conveyor rolls (16) over associated lengths (26,28,30) of the conveyor that are selectively adjustable to provide a desired transition between adjacent conveyor sections driven by different drive loops. First and second electric motor drives (32,34) respectively drive the loops to provide synchronous or independent glass sheet conveyance over the different lengths of the conveyor. A pair of each of the first and second drive loops (22,24) are preferably utilized with opposite ends of the conveyor rolls supported thereon and having driven and reduced size portions (88,90 and 86,92) that permit end-for-end roll repositioning to adjust the transition between the driving of the loops. The preferred construction utilizes chains as the drive loops (22,24) with the roll ends projecting outwardly through side slots (66) in the furnace (18) for frictional driving of the rolls by the chains.

    • Sheet glass is heated during conveyance within a furnace housing having a fixed roof and vertically movable side doors that define side slots through which ends of conveyor rolls project outwardly to be supported and frictionally driven by continuous drive loops slidably driven over external support surfaces that extend alongside the side slots. A vacuum holder of the apparatus is positioned within the furnace housing above the conveyor and has a downwardly facing surface with spaced openings in which a vacuum is drawn to receive a glass sheet from the conveyor and support the sheet above the conveyor. The holder surface is disclosed as being both planar and curved and as having a porous cover of ceramic fibers so as to distribute the vacuum and prevent marring of the glass as it is supported. A greater vacuum is drawn to initially support the glass and a lesser vacuum is subsequently drawn to prevent glass deformation at the spaced openings. Vertically movable auxiliary lifters positioned between the rolls or vertical movement of the vacuum holder facilitates glass pickup. Sensing of the glass position along the conveyor and operation of a locator cooperatively provide accurate positioning of the glass on the holder surface without requiring the conveyor to be stopped prior to the holder operation. A carrier mold ring moves under the supported glass and the vacuum is then terminated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows thin glass to be accurately bent. Subsequently the mold ring is moved from the furnace to a quench unit between upper and lower blastheads that temper the bent glass. Increased air is then supplied to the lower blasthead relative to the upper blasthead to lift the glass sheet off the ring and allow return of the ring to the furnace.

    • A spring end cap for use in rotatably driving a glass conveyor roll of ceramic is disclosed as incorporating helical spring coils that clamp onto an end of the roll. Each spring coil has a diameter in an undeflected condition slightly less than the diameter of the roll end so that coil deflection increasing the coil diameter allows the coils to receive the roll end prior to being released in order to clamp over a round outer surface of the end. Different embodiments of the end cap are utilized with frictionally driven rolls as well as with toothed sprocket or gear driven rolls. Ease of installation is achieved when the spring coils are all part of a single helical spring. The end cap can also be utilized to repair a broken roll end and then must include at least three helical springs whose coils are axially threaded so as to provide circumferentially spaced clamping that secures the broken roll end to the rest of the roll at the fracture.

    • A furnace for treating glass sheet material and the like in a glass tempering system. The furnace includes an upper glass treating zone and a lower gas treating and distributing zone for homogenizing gases of different temperatures to minimize exposure of the sheet being treated in the treating zone to uneven temperatures. Diametrically opposed inlets and outlets are provided in the side walls controlled by doors, and a slot in the top wall extends between the inlets and outlets to permit movement of a material carrier through the furnace. A pressure chamber communicates with the slot to cool conveyor elements at the top of the furnace, and also to provide a pressure barrier resisting the escape of gases from the furnace through the slots. Air curtains impinge on the tops of the doors in their closed positions to reduce leakage at the top of the doors.
