An engineer will quickly know by the soundwhen an inspirator breaks. THE HANCOCK COMPOSITE LOCOMOTIVEINSPIRATOR. The composite is a compound Hancock inspirator,consisting of two separate and individual inspiratorswithin one body, which can be operated separately orsimultaneously, as desired.

This instrument enables two inspirators to be connected with practically the expense of connecting one,thus giving two independent ways of feeding the11 162 LOCOMOTIVE APPLIANCES. boiler. By making practice of operating one instru-ment one time, and the other the next, both are con-stantly kept in perfect working order. The com-posite takes up practically no more room than asingle instrument. Where it may be desired to locate both injectors onone side of the locomotive convenient to either theengineer or fireman who has charge of pumping theengine, or on the boiler butt available to both, theadvantages of the composite are apparent. This instrument can be used and a steady feed keptwhen there is a great variation in the power the various combinations of nozzles used it ispossible to keep a steady
