9. DRIVER, TENDER, and TRUCK-BRAKE CYLINDERS, CUT-OUT COCKS, AIR STRAINERS, HOSE COUPLINGS, FITTINGS, etc., incidental to the piping. (The 1-inch Cut-out Cock in Brake Pipe directly beneath the automatic brake-valve (Fig. 1) is designated the DOUBLE-HEADING COCK). Names of Piping NAMES OF PIPING. (See Fig. 1. Notations thereon as to pipe connections.) In the color scheme of Fig. 1, it is not implied that the indicated pressures are in all of the several pipes at the same time; the intention is to explain the routing of the air flow, and the zone that may be occupied by each pressure. In subsequent charts, the coloring will indicate the pressures that are contained in the pipes, chambers, etc., during the particular phase of action represented by the individual plate. DISCHARGE PIPE: Connects the AIR PUMP to the first MAIN RESERVOIR. CONNECTING PIPE: Connects the two MAIN RES ERVOIRS. MAIN-RESERVOIR PIPE: Connects the second MAIN RESERVOIR to the AUTOMATIC BRAKE-VALVE, DISTRIBUTING VALVE, FEED VALVE, REDUCING VALVE, and PUMP GOVERNOR. FEED-VALVE PIPE: Connects the FEED VALVE to the AUTOMATIC BRAKE-VALVE. EXCESS-PRESSURE GOVERNOR PIPE: Connects the FEED-VALVE PIPE to the EXCESS-PRESSURE HEAD of the PUMP GOVERNOR. REDUCING -VALVE PIPE: Connects the REDUCING VALVE to the INDEPENDENT Brake-Valve, and to the SIGNAL SYSTEM. BRAKE PIPE (Formerly "train line."): Connects the AUTOMATIC BRAKE-VALVE with the DISTRIBUTING VALVE and all TRIPLE VALVES on the cars in the train. BRAKE-CYLINDER PIPE: Connects the DISTRIBUTING VALVE with the DRIVER, TENDER and TRUCKBRAKE CYLINDERS. APPLICATION-CYLINDER PIPE: Connects the APPLICATION CYLINDER of the DISTRIBUTING VALVE with the INDEPENDENT and AUTOMATIC BRAKE-VALVES. DISTRIBUTING-VALVE RELEASE PIPE: Connects the APPLICATION-CYLINDER exhaust port of the DISTRIBUTING VALVE to the AUTOMATIC BRAKE-VALVE through the INDEPENDENT BRAKE-VALVE. |
