Abstract

845,965. Bending glass sheets. PITTSBURGH PLATE GLASS CO. Aug. 17, 1956 [Aug. 30, 1955], No. 27621/59. Divided out of 845,961. Drawings to Specification. Class 56. A sectionalised mould providing a substantially continuous shaping surface conforming to the shape desired for a bent glass sheet comprises a moulding member relatively movable with respect to the remainder of the mould and a holding device associated therewith and adapted to be tripped to permit the movable member to move into a closed mould position to help provide the shaping surface. The apparatus disclosed forms part of the apparatus described in Specification 845,961.
