Allworking parts are on the out-side, in plain sight, and easilyaccessible. This trap is located G ft. ormore above the water-line of theboiler. The-water from the con-densing surfaces is forced bythe pressure of the steam be-hind, through a pipe leading tothe trap, with a swing checkvalve close to the latter.

As soon as the receiver isempty it tilts back as before and again refills. The trap isprompt in opening and closing, its action being entirely dueto gravity. When once set up it requires no further atten-tion. It takes the water from the condensing surfaces, July, 1903.

Thereis no outlet by which the steam can be wasted. The trap issaid to be quick and positive in delivering the water into laeboiler against any pressure, and regardless of fluctuations ofpressure. It supplies all the water needed in the boiler fromduties of a pump or injector. It is reported to operate equal
