Abstract

152,240. Hoffman, F. I. Dec. 23, 1919. Diaphragm horns. - A diaphragm sounding-device for motor-vehicles &c. comprises a camw h e e 1 3, preferably weighted, slidably mounted on a fixed spindle 4, and adjusted automatically by means shown as a compression spring 10. Instead of the helical spring 10, a leaf spring may be employed. The cam wheel is operated through a gear-wheel 7 by any well-known means.
