Triplex toughened glass dating
Clarence Avery, a Ford employee, began working with Pilkington Co., a British glass manufacturer, on a new glass-making process.By the end of 1919 they had perfected a process for pouring molten glass through rollers and onto a mobile table.Unfortunately, it was costly and both manufacturers and drivers had a strong interest in keeping cars affordable.Though Benedictus was granted a patent in 1909, the product was not put into use until World War I when laminated glass was used in the goggles of gas masks.Meanwhile Wood had also been working with cellulose and devised another method for adding a protective layer (originally tree resin, later cellulose) between two pieces of glass and creating shatter-resistant glass. Benedictus, in 1910, added a gelatin layer which stuck to both panes of glass and patented Triplex. Also about this time a new urethane glue was also used to bond the glass to the frame.The Triplex Glass Company was founded in 1923 and Triplex glass was brought to the U. The laminated window was more secure and if it broke it broke in a spider's web pattern rather than splintering into small shards.Because it was difficult to penetrate, it also kept passengers from being ejected.Its strength actually meant more structural integrity for the car if it rolled over.
When one of these early cars was involved in an accident, it was not uncommon for the driver at a minimum to be injured by flying shards of glass or, far worse, lose his life after going headfirst through the windshield.

In 1904 when the first windshields were introduced, most were a horizontally-divided piece of plate glass just like the glass used for house windows.
Later as Benedictus climbed a ladder, he bumped that shelf, once again sending the flask to the floor. Cellulose nitrate, a clear liquid plastic left in the beaker, had dried and kept the glass from breaking into shards.
After experimenting further Benedictus developed safety glass, two layers of plate glass with a layer of cellulose between them, and he hoped to promote its use in automobiles.
There are also stories that Henry Ford and some of his closest friends were themselves injured by flying glass in accidents.
