At the convention of the National Association of Fire Engineers at Milwaukee, Gustave Andreen, Omaha, Neb., exhibited his patent fireproof shutter and received strong recommendation from the exhibit committee. The invention allows shutters equipped with it to be operated from the interior of the building without raising the window, and requires no effort, as is the case with the old style swinging shutters, to close them. Another advantage claimed for this device is that firemen can readily open the shutters from the outside while standing on a ladder, or by water pressure from the hose, thus saving much time in getting at the fire. The lever, which is easily worked from the inside, can open all the shutters on one story or the full side of the building. Without doubt the device has great merit and will be extensively used in all modern buildings.
