Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . lveto the exhaust port of the cnjrino triple; a three-quarter inch pipe connectsthe valve directly with the brake cylin-ders on the engine and tender; a half-inch pipe connects the valve to the aux-iliary reservoir, and in this pipe there islocated at any convenient point an auto-matic reducing valve, which is usuallyset at 45 lbs.; a three-quarter inch pipeconnects the valve to the auxiliary res-ervoir pipe of the engine and tender;the main exhaust in the control valve isnot connected to any pipe. The engineand tender auxiliary reservoirs are con-nected with a half-inch pipe. As only one triple valve is requiredon the engine and tender, there is a by-pass connection made from the trainpipe to the auxiliary reservoir with ahalf-inch pipe, and in the by-pass thereis a non-return check valve and a re-ducing diaphragm with a one-eighthinch opening; this by-pass enables theengine and tender auxiliary reservoirsto be charged up as quickly as thoughthere were two triple valves; with this r^.

In piping the straight air controlvalve there is a safety valve on thepipe between the brake cylinders on theengine, but this safety valve is not usedwhen the Dukesmith automatic releasesignal is placed on the engine, as therelease signal not only serves the samepurpose of the old style safety valve,but is also a gauge, as it indicates atall times just what the pressure is in thebrake cylinders.
