Abstract

768,781. Bending. glass. LIBBEY-OWENSFORD GLASS CO. April 19, 1955 [Nov. 10, 1954], No 11219/55. Class 56 In the bending of glass sheets 29 by passing them on shaping moulds 26 through a heated chamber 15 the bulk of the heating is supplied by radiant heaters 22 in the roof 16 which direct preformed beams of radiant heat on to the surface of the sheet. Selected heaters only are fired according to a predetermined pattern designed according to the type of bend to be effected. Additional heat is supplied by heaters 21 in the walls of the furnace below the moulds arid by batteries of burners 23. adjustable in position by the mechanism 39.
