NEW FIRE-PROTECTIVE WINDOW FRAME.

NEW FIRE-PROTECTIVE WINDOW FRAME.

W. D. Wasson, of Chicago, has invented a new window frame designed to do away with the outside iron fire-protective shutters. It is manufactured by a Philadelphia firm, and was recently subjected to a very severe half hour’s test under a fierce fire,after which a line of hose was turned directly against the frame and glass. Inspector McDevitt, of the Fire Underwriters’ association, then inspected the w indow, which had been built into a small brick building erected for the purpose. He said he found the frame in good repair and that it moved easily. A second test was next made by piling oak and pine wood inside the little building, then pouring oil over before the match was touched. This blaze was also kept going for half an hour, and the same frame came out in as good condition as after the former test.
