Abstract

1,254,014. Fog horns. KOCKUMS MEKANISKA VERKSTADS A.B. 8 Jan., 1970 [9 Jan., 1969], No. 945/70. Heading G5J. In a gaseous driven sound transmitter, having a diaphragm which oscillates during signalling, a support member 12 is situated in the outlet passage 5 adjacent the diaphragm 7. The support member is spaced from the diaphragm a distance greater than the deflection of the diaphragm towards the support member during oscillation, but smaller than the maximum diaphragm deflection at which permanent deformation does not occur. The support member may consist of a ring 13, screwed into a threaded recess, with a number of thin cams 14 projecting towards the diaphragm, the surfaces 15 of which follow the curvature of the diaphragm when it is in contact with the cams. Alternatively, the support member may consist of a ring, with a number of support legs carrying a support ring concentric with the diaphragm. Using one of these arrangements, undue stresses in the diaphragm material will not exceed permissable values.
