“TRIPLEX” GLASS

H COME INTO GENERAL USE> . ye an idea of how engineers experts regard triplex unglass for motor-car windj S interesting to note the "it ’of a. recent poll in America of " >sU v- councils, engineers, automobile and impartial students of mod- *" trends in the motor industry. The ,r “ .7 p ( 'the voting was that 40 per t*were of the opinion that non‘hattprnble glass was the most essen--1 oending change in the modern car, 1111 cen t. voted for automatic chas- ' fabrication, while the balance voted ,IS oilier general improvements. Triplex. which is standard on the new r «1 car Windshiels. is a non-shatter--1 , c iear-vision glass with no wires its structure, and consists briefly of ou t9ide layers of glass with a ,; d „l 9 binding layer of plastic. The ““ are welded together under heat id pressure, and the product passes ““ »h it different operations before passed as Triplex. During the war aviators were proved by goggles and windshields made [ Triplex glass, while the glass for Submarines and safety screens for high-speed submarine chasers was also pf’this same material. Flying glass, usually from windtik'lds, is responsible for 65 per cent, if all injuries incurred in automobile accidents in America. This unshatter- . ole glass, which by actual test is 50 wr cent, stronger than plate-glass of l.mal thickness, will not do more than .rack There arc no flying splinters or figged edges. Although flexible under Minpuct, it cannot be cut with a diamond.
