Página 103 - Each cylinder with its valve chest is cast separately and is separate from the saddle. The steam connections are. made by a pipe from the saddle to the highpressure valve chest, and the final exhaust takes place through an adjustable connection between- the lowpressure cylinder and the saddle casting. The valve, which is double and hollow, admits steam to the highpressure cylinder, and at the same time distributes the high-pressure exhaust from the front end of the highpressure cylinder to the back...
Página 103 - A is the high-pressure valve by which steam is conducted from the livesteam openings through external cavities B and B to the high-pressure cylinder. The exhaust from the high-pressure cylinder passes through the opening C to the steam chest, which acts as a receiver; D is the low-pressure valve connected to the high-pressure valve by valve rod E. This valve in its operation is similar to the ordinary slide valve. The outside edges control the admission, and the exhaust takes place through the external...
Página 117 - The same cock acts as a cylinder cock for the high-pressure cylinder and is operated by the same lever that operates the ordinary cylinder cocks, thus making a simple and efficient device, and one that need not become disarranged. This valve should be kept shut as much as possible, as its indiscriminate use reduces the economy and makes the locomotive ''logy.
Página 117 - ... in starting these locomotives with full trains from a state of rest, it is necessary to admit steam to the low-pressure cylinder as well as to the high-pressure cylinder, which is accomplished by the use of a starting valve (Fig.

Página 116 - Cases are reported where compound locomotives of this system have hauled passenger trains long distances with broken valve-stems and broken valves, the parts being kept in their proper relation while running by the compression due to the variation mentioned. To avoid the possibility of breaking, it is the present practice to pass the valve-stem through the valve and secure it by a nut on the front end.

Página 60 - FIGURE 151 reducing valve C is operated automatically by the pressure in the receiver. To this end the port E is provided, communicating with the receiver, and the space in front of the reducing valve; as the pressure rises the steam acts on the large end of the reducing valve, causing it to move backward...
Página 56 - F, by the pressure in chamber E, and the engine runs simple as before. When the grade is passed, the engineer pushes the handle of the three-way cock over and the engine begins to work compound. To start the engine compound the separate exhaust valve is left closed, as in Fig.
