ABSTRACT:
A heated glass sheet topside support device (22,22',22a,22a') is disclosed as including horizontally extending lower and upper plates (38,46) connected by a set of vertically extending passage members embodied by tubes (54) or plate members (54a) to define passages (55,55a,55a'). The support device also includes first and second manifolds (56,58) for supplying pressurized gas and a vacuum through first and second sets of holes (42,42a,42a';44,44a,44a') in the lower plate so as to thereby support a heated glass sheet below the lower plate without any engagement. In one construction, the pressurized gas is supplied through a chamber (48,48a) between the plates through a set of shorter tubes (80,80a) mounted within the first set of holes (42,42a) in the lower plate (38,38a), and the vacuum is drawn from the upper side of the upper plate (46,46a) through the holes (52,52a) therein and through the passages (55,55a) and the second set of holes (44,44a) in the lower plate. In another construction, the vacuum is drawn through the chamber (48,48a') between the plates through the first set of holes (42,42a') in the lower plate (38,38a'), and the pressurized gas is supplied through the holes (52,52a') therein and through the passages (55,55a') and the second set of holes (44,44a') in the lower plate. Each embodiment of the topside support device is supported by fused silica posts (86) that preferably have upper ends including inverted cup-shaped members (102) on which the topside support device is slidably mounted by an associated spherical bearing (106). Positioners (118) for the silica posts (86) and support device locators (134) cooperate in supporting and positioning the topside support device at the proper location.
