Stillwell, consulting engi-neer. RAILWAY AND LOCOMOTIVE ENGINEERING. May, 1910. Air Brake Department Conducted by G. W. Kiehm Triple Valve Test Rack. FUNCTIONS OF THE VALVES AND COCKS OFTHE TESTING RACK. Valve I. 2. Direct opening to brake pipe 3. 4. Brake pipe exhaust through 1/32 S- Brake pipe exhaust through 3/64 6. Brake pipe exhaust through 1/16 7. Brake pipe exhaust through 5/64 opening. Cock communication between themain reservoir and testing rack. Cock X. Used in clamping triple valve to triplevalve stand face to admit air to andexhaust it from the clamping cylinder. Cock Y. To be used if triple valve is of thepipeless type, to permit brake pipe airto flow to the triple valve. Cock Z. To be used if triple valve has brakepipe connection to the check valve PIPING DIAGR.^M OF WESTINGHOUSE TEST RACK. Position 8. Brake pipe exhaust forrapid reduction. Valve B. Position I. Brake pipe pressure underdiaphragm, auxiliary pres-sure above diaphragm. Position 2. By-pass brake pipe air toauxiliary reservoir. Position 3. Lap. Position 4. Brake pipe pressure overdiaphragm, auxiliary pres-sure under diaphragm. Valve C. Used for controlling air from mainreservoir to the auxiliary reservoir dur-ing service port capacity test and foradjusting the safety valve. Valve J. Notches determine the rate of feed upof the brake pipe volume. Cock I. Controls communication betweenbrake pipe and triple valve and used tooperate triple valve in quick action. Cock 2. Closed to obtain reduced auxiliaryvolume, open to obtain maximum aux-iliary volume. Cock 3. Closed to obtain reduced brake cylin-der volume, open to obtain maximumbrake cylinder volume. Cock 4. To exhaust
