ABSTRACT:
An improved glass sheet quench (14) is disclosed as including opposed blastheads (26,28) each of which includes elongated plenum housings (34) including openings (42) positioned therealong in a spaced relationship and oriented to supply jets (44) of quenching gas angularly in opposite directions from the plenum housing toward a heated glass sheet therebetween for impingement therewith to cool the glass sheet. This angular supply of the quenching jets permits the use of half as many plenum housings as is ordinarily needed such that the plenum housings can be spaced farther from each other to provide a greater flow area for spent quenching gas to escape from between the blastheads. Flat glass embodiments of the quench (14,14a) and bent glass embodiments of the quench (14' 14a) are disclosed and may incorporate sheet metal and tube plenum housings (34) or drilled metal bar plenum housings (34').
