Abstract
A cylindrical adapter to a fire nozzle is disclosed which produces not only a forward stream but also at the same time a second rearward directed safety spray cone shaped bubble which encloses the fireman and any persons or property being rescued. This adjustable cone shaped bubble protects the fireman by reducing the radiant heat felt by the fireman as well as dangerous gases. Also is taught a small pipe centered in the cylinder with the purpose to allow a shaft to be inserted therein. This shaft can be used to control the forward stream in future models of the invention.
