Abstract

699,068. Glass bending and tempering. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. June 27, 1952 [June 28, 1951], No. 16204/52. Class 56. A sheet of glass 1 is shaped and tempered by bringing the sheet in a pliable condition between two discontinuous surfaces each formed on a shaping element 4 and movable towards and away from each other, interposing a continuous surface 8<SP>1</SP> between each face of the sheet and the respective discontinuous surface, moving the shaping elements towards each other to shape the sheet therebetween, moving the shaping elements apart, displacing the discontinuous surfaces, and projecting a chilling medium on to the shaped faces of the sheet through the discontinuities 10 in the surfaces of the shaping elements. The surfaces 4 are apertured at 10 and form the front walls of air boxes 5 carried by stirrups 6<SP>1</SP> rigidly connected to rods 6 associated with the power means by which the boxes are reciprocated. Air is supplied to the boxes through connections 7. The continuous surfaces are either formed from a substantially non-combustible material or are provided with a heatresisting coating. The continuous surface shown is of glass cloth 8<SP>1</SP> carried in frames 8 of flexible, e.g. spring steel, which return to their normal shape after the shaping operation, but rigid surfaces could be used. The discontinuous surfaces 4 may be provided by a framework of parallel spaced rods arranged to give the required shape, the continuous surface then being a rigid refractory material.
