ABSTRACT:
In tempering glass sheets vertically hung from tongs, the uniformity with which tempering medium is applied toward the glass sheets during quenching is improved by providing the quenching apparatus with means to provide finer control of the flow rate of tempering medium against the opposite major surfaces of the glass sheets than one gets from valving branch conduits in order to prevent side-to-side swaying of the glass sheets during quenching, particularly when the sheets are curved. Such means to provide fine control is also useful in quenching glass sheets supported in other than vertical orientations during quenching.
