Abstract

767,059. Electric horns. TRIX, Ltd. Jan. 21, 1955 [Nov. 18, 1954], No. 33474/54. Class 13. [Also in Group XV] A hooter for a toy electric railway, or a similar sound generator, comprises a diaphragm 11 mounted on a solid base 1, a hollow sound chamber 8 secured to the base over the diaphragm, an electromagnet 12 located inside the chamber 8, and an interrupter contact spring 4 fitted in a recess in the base 1 and adapted to make contact with a rivet at the centre of the diaphragm 11. The size of a hole 10 in the sound chamber 8 affects the nature of the sound emitted. The diaphragm 11 is preferably made of a synthetic resin, an iron armature 13 being secured to it by means of the above-mentioned rivet.
