Abstract

119,325. Monnot, J. F. Nov. 6, 1917. Diaphragm vibrators.-A warning or signal device suitable for large works or on aircraft comprises a number of diaphragms a supported' on a frame or casing b adapted to be rotated relatively to a fixed wheel or cam c. As shown, the casing b is rotated by a shaft d operated by an electric motor or other means or, if the device is for use in connexion with aircraft, from a propeller shaft. According to the Provisional Specification, the casing may be fixed and the wheel rotated, or the casing and wheel may be rotated in opposite directions.
