Thewater outlet is kept perfectly closed by a bronze cap, retainedby two levers, whose ends are in turn secured by a fusible link,consisting of two bronze plates transversely corrugated andsoldered together. As soon as the air about any sprinkler head, by reason ofcombustion, reaches a given temperature—usually 165 deg. F.—the solder link in the head melts. Thereupon the valve capwhich closes the outlet end of the water-supply pipe is re-leased. Water then pours through the opening against thedistributor, and is spread over the ceiling and floor of thebuilding. The International head distributes water perfectly, above,. DETAILS OF SPRINKLER HEAD below, and for a desired distance around—in large drops andnot in a fine spray, which runs into steam too rapidly to com-bat a fire successfully. The fusible link, due to its thin design and exposed location,is very sensitive to heat and certain in operation. The entiredevice incorporates in itself a spring,ensuring the promptest action at ratedtemperatures. Experience with this design in largequantities for many years has proven itfree from accidental injury no matterwhere installed. The Internationalhead is made in four different fusingtemperatures, namely : 165 deg., 212 deg.,280 deg., and 360 deg. This head is made of standard size,same as cut; and also in Jumbo size,which is four times as large as stand-ard, for rare application at points re-quiring a large discharge of water. The International eave sprinklerillustrated is made of bronze and is used to protect the ex-teriors of buildings, and wall and window openings. Oth
