Excerpt from Air Brake of the Science of Railways Referring to Fig. 1-b, air compressed by the pump passes through pipes D and C as usual to the main reservoirs and the main-reservoir pipe, mr. The main-reservoir cut-out cock, W, is to cut Off and vent the air from the main-reservoir pipe, when removing any Of the apparatus except the governor. The end to ward the main reservoir is tapped for a pipe connection, G, to the Pump Governor. Before this cock is closed the double-heading cock, X, should be closed, and the brake-valve handle placed In release position. This is to prevent the slide valve Of the feed valve, and the rotary valve of the brake valve, being lifted from their seats. Beyond the main-reservoir cut-out cock, the main-reservoir pipe has four branches, one of which runs to the automatic brake valve, one to the feed valve, one to the reducing valve, and one to the dis tributing valve. As a result, the automatic brake valve receives air, from the main reservoirs in two ways, one direct and the other through the Feed Valve.
