Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . o the port c, tothe pipe connection d. on the three-waycnck and valves to the whistle, soundingit until the equilibrium is restored on thetwo sides of the diaphragm. Fig. 4 shows the car-brake valve forapplication of the brakes and the givingof signals. The connection from themain brake pipe is made to the port f,leading into the chamber F. A secondcliamber. G, has a connection, g. leadingto the atmosphere. The chambers F andG communicate through a port closed bya valve having a rubber face, which isheld in its seat by a small spiral springassisted by the air pressure. The cordextending through the car is attached tothe lever H, and, when pulled, opens theport between the chambers F and G,discharging the air through the port G and into a small pipe leading throughthe bottom of the car. As will be seen,the signal valve is really the beginningof the present conductors valve which isnow used to apply brakes only. In addition to this patent held by theWestinghouse Co., a number oT similar. patents have been gotten out by railroadand air-brake men from time to readers will recognize the weaknessof the scheme in the fact that signalscannot be given at the moment that
