Abstract
362,161. Devices for producing audible signals. MONNOT, J. F. and KLAXON, Ltd., 36, Blandford Street, Portman Square, London. Dec. 4, 1930, No. 36661. [Class 13.] The contacts J for making and breaking the circuit of an electromagnet B which actuates a diaphragm D to produce an audible signal are carried one on a flexible member G adapted to be moved by an actuating member connected to the diaphragm and the other on a comparatively rigid member F adjustable relatively to it. As shown, the flexible arm G and rigid member F are both clamped at one end by a screw E<1> to a boss E on a member A which houses the electromagnet B. The other end of the member F is adjustably held on the member A by a screw F<1> and lock-nut F<2> and the free end of the member G rests on the rear end of the actuating member K which passes through an aperture in the member F and carries an armature K<1> by which the diaphragm D is actuated. Adjustment of the member F by deflection towards the diaphragm enables the arm G to move by its own resiliency in the same direction, while movement of the member F away from the diaphragm D is effected by its own resiliency and carries the arm G with it.
