Abstract
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 surface 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 axis from a desired, adjusted orientation to optimize the heat exchange effect of the moving blasts of tempering fluid.
