11T was announced this week by
Lancegaye Safety Glass (1934), Ltd., Hythe Road, London, N.W.10, that this concern has practically completed plans for the manufacture of raw glass, in addition to its activities in the production of the well-known toughened and laminated safety glass, with which its name is commonly associated.
From its 4i-acre works, which are now working 24 hours a day, the output for the next 12 months is estimated at 4,000,900 sq. ft. of safety glass, as compared with 1,250,000 sq. ft. in 1937 and 500,000 sq. ft. in 1934. Contracts have been arranged with 14 automobile makers, whilst Lancegaye glass is used extensively by the Admiralty, War Office, Air Ministry, London Transport, L.C.C., important provincial corporations, and three railway companies.
As an indication of the low cost of Lancegaye toughened glass, it is stated that it can be offered, in most cases, at only 10 per cent. more than ordinary plate glass.
The cnmpany has recently concluded arrangements for the absorption of its associated concern, Gilt Edge Safety Glass, Ltd., Stone, Staffs, which will be incorporated as Lancegaye (Northern). Ltd., and will afford service for the north of England and for Scotland. Its associated company in Ireland has completed the erection of a new factory and has secured the business of many vehicle concerns in that country.
During a recent tour of the Lancegays works, we witnessed a number of highly interesting tests. A 2-lb. ball was allowed to fall on a. plate of f-in. glass resting on two supports about 18 ins. apart. The normal drop is about 4 ft. 6 ins., but in our presence the distance was increased to 6 ft. 6 ins, before the glass shattered.
Local temperature change was another test demonstrated. Molten lead was poured on cold glass, in the one case, and water, on hot glass, in another. There were no undesirable consequences.
Then a 2i-lb. weight was dropped 10 ft. on to a 1-ft. 6-in, disc of i-in. glass supported only at its edges. Several trials failed to cause a breakage.
After this, a girl gave a demonstration of skipping on a sheet of i-in. toughened glass, which flexed under her weight, but did not break, and, finally, a cricket ball was bowled from short range at a vertical plate supported only at the base and behind which a man stood.
