Abstract: 839,278. Bending glass sheets. PITTSBURGH PLATE GLASS CO. May 15, 1958 [May 27, 1957], No. 15629/58. Class 56. In a skeleton mould for bending glass sheets, particularly for vehicle backlights, the longitudinal parts of the side rails 30, 32 of the centre and wing portions, respectively, that contact the undersurface of the sheet have a higher heat capacity per unit length than the parts away from the sheet. This may be effected by forming more apertures 42, Fig. 3, in the more remote parts than are formed, at 40, in the glass-contacting parts, or by making apertures 44, Fig. 4, in the more remote parts only. When the sheet, bent to the line N of the unstressed mould, is tempered on the mould the latter warps away from the bent sheet to the line 100 and this facilitates the removal of the tempered bent sheet from the mould.
