<p>A spring would bell-shaped dispensing housing is constrained against rotational movement by a band secured to the housing and a non-rotatable bottom plate. The band, which is locked in position by a fusible element, also serves to seal the liquid or chemical dispensing apertures which are peripherally disposed about the bottom portion of the bell-shaped housing. When the fusible element parts in the presence of an abnormally high temperature condition, signalling the presence of an incendiary situation, the band falls away from the bottom plate and the housing simultaneously permitting the spring would housing to commence rotating and the liquid or chemical extinguisher to be discharged through the peripherally disposed apertures. The rotating bell-shaped housing, through its generated centrifugal force, will expel the extinguishing liquid or chemical in a well defined circular pattern over the burning area.</p> |
