Abstract

144,860. Fellows, D. V. L. Aug. 27,1919. Diaphragm horns.-In an electric horn of the type in which a diaphragm or anvil member thereon is struck by a hammer, the vibration of the diaphragm is damped in one direction by means of a stop or stops, while it may vibrate more or less freely in the opposite direction. As shown, the anvil 8 is adjustably mounted in a conical bush 9 secured to the diaphragm and adapted to engage a corresponding coned recess 12 in the base-plate 2, so that the diaphragm, while free to vibrate in the direction of the blow from the hammer 7, has its vibrations damped in the opposite direction.
