Abstract
16,467. Oviedo, F. E. July 14. Alarms operated by fusible devices.-Relates to alarms of the kind in which a weight descends and closes an electric circuit when released by the melting of a fusible substance. A cord or wire 13 is passed around, and secured by wax &c. to hooks 11 arranged round the edge of a base 1, and is then passed through an eye 12, a weight 15 being attached to its end. When the wax &c. melts, the weight 15 falls, and chains 8 attached thereto pull down spring contact-pieces 6, 7 into contact with pieces 3, 4, thus closing a single circuit or two complementary circuits. The circuit contains a bell and a drop indicator, which in falling closes an electric - light circuit, and operates a trip adapted to stop a clock and thereby give an indication of the time of the fire.
