Abstract
2380. Lucas, H., and Edwards, W. H. Jan. 29. Diaphragm horns.-In electric diaphragm horns, the electro-magnet has a pair of cores a arranged in alinement on a circular or other yoke-piece h, and the adjacent pole tips b are formed with oppositely inclined faces between which operate the armature c carrying the diaphragm striker j. The armature is mounted on the spring member d of the interrupter device.
