With this object in view, thiscompany has prepared the valves illus-trated and described herewith. To attach the reducing valve, Fig. i,connect fitting 30 with a nipple to airtank and pipe to water reservoirs fromZ, inserting two cocks in this pipe. At-tach levers to the cock handles and ex-tend same to opposite sides of car. Closeone cock before recharging water valve is adjusted to deliver 20 poundspressure on the water for forcing itthroughout the car. Necessary readjust-ments are made with nut 27.

As the air pressure in the watertanks diminishes from the use of water,the pressure on piston 20 is likewiseaffected, and, rising, opens valve 18 andrestores the air pressure. Attach the governor, Fig. 2, to air tankwith a nipple at X, and from fitting 46(W) extend pipe to auxiliary reservoir. CONDUCTED BY P. M. NBLLIS. The pressure on spring 42 is such that apressure in chamber c of 60 pounds ondiaphragm 40 is required to raise its valvefrom its seat. Therefore the auxiliaryreservoir of the air brake is charged tothis extent for braking the train beforeany pressure passes to the air tank of thewater-supply system. Air pressure from the auxiliary reser-voir entering the valve at W reacheschamber c through por
