NEW WINDOW SHUTTER
Device Against Thieves f —— Representatives of the metropolitan police aud Insurance companies met recently in a workshop off Great Portland Street, London, to watch a demonstration of an invention to prevent smash-and-grab raids. The inventor is Mr. W. J. Samuel, aged 57, an engineer at Chatham dock, yard, aud when tlie representatives arrived they found him standing in front of a (hick plate-glass window with a brick in bls hand. He threw the brick through the window, and immediately a shutter fell with such rapidity that it would have been impossible for anyone to put his hand through the hole in the glass. The invention is claimed to be so simple that there is very little possibility of anything going wrong. A« soon as the window receives any violent pressure a small spring at the top releases another spring, which, in turn, releases the steel shutter.
