TEMPERING FLAT OR CURVED GLASS SHEETS Abstract of the Disclosure Apparatus for tempering flat or curved glass sheets suspended in a vertical orientation comprising a plurality of nozzle boxes each pivotable about its longitudinal axis and adjustable in position to provide a pair of sets of nozzle boxes facing the opposite major surfaces of a glass sheet held in a quenching position between two sets of nozzle boxes. The present apparatus requires a minimum of power to cause relative movement of blasts of tempering fluid applied against the opposite major glass sheet surfaces, permits positional adjustment of individual nozzle boxes to define a flat or curved space corresponding to the shape of glass sheet handled, and simultaneously permits each nozzle box to oscillate about its longitudinal axes from a desired, adjusted orientation to optimize the heat exchange effect of the moving blasts of tempering fluid applied via the nozzles of said nozzle boxes against the opposite major surfaces of said glass sheets that are quenched. A method of using this apparatus is also covered.
