Abstract

210,558. Monnot, J. F. Nov. 14, 1922. Diaphragm horns.-A horn of the type in which a diaphragm 8 is vibrated by a striker 14 secured to the armature 4 of a self-interrupting magnet 2 comprises the following features : (1) The spring controlling the armature is a triangular plate 16, Fig. 2, rigidly fixed at two points 17, 17a spaced apart, and free from clamping means between these points the striker arm being secured at a point 18 outside the line 17, 17a. (2) The movable contact 19 is carried by a leaf spring 20 secured at both its ends, and is operated by an adjustable screw carried on the projection 25 of the spring 16. (3) A resistance 27 connected across the interrupter contacts 19, 21 in order to reduce sparking is wound non-inductively around the main electromagnet winding 2. (4) The cup-shaped outer casing of the electromagnet is screw-threaded and has secured thereto a flared ring 5 for supporting the diaphragm 8, and also carries a frame ring 11 having two rearwardly extending brackets 12, 12<a> to which are secured the armature-controlling spring 16, the leaf spring 20 carrying the movable contact and a relatively-rigid member 24 carrying the adjustable fixed contact 21.
