摘要： A brake pipe control apparatus of the type that defines primary and control passage networks has been improved. The primary passage network interconnects the brake pipe to at least one pneumatic valve in the apparatus. The control passage network interconnects a source of control pressure to at least one magnet valve used to cause operation of the pneumatic valve(s). The improvement includes first and second check valves and a passageway added between the two passage networks. The first check valve is incorporated into the control passage network between an inlet channel thereof that connects to the source and a branched channel thereof that connects to the magnet valve(s). The first check valve is situated to prevent air from flowing to the source from the branched channel when pressure in the source is low relative to pressure in the branched channel. The passageway interconnects the branched channel and the primary passage network. Placed into the passageway, the second check valve is situated to allow air to flow from the primary passage network to the branched channel when pressure in the source is low relative to pressure in the brake pipe. Pressure is thus maintained in the branched channel thereby allowing the magnet valve(s) during operation thereof to cause proper operation of the pneumatic valve(s) of the apparatus even if the source fails to provide air at the control pressure ordinarily expected.

摘要： A handle assembly, of the type used in railway locomotives, which includes a base plate, a cam mount attached to the base plate, a cam disk and a shaft assembly interconnecting the mount and disk to allow rotation of the disk. The improvement includes a yoke, a bail bar, first and second bearing members anchored to the plate and first and second switches attached to the plate. Pivotally connected to the disk and accommodating a handle, the yoke rotates along with the disk as the handle is moved along its range of motion and tilts as the handle is moved perpendicularly thereto. The bail bar is rotatable between the first and second bearing members. A first mechanism imparts a rotational force to the bail bar so that its middle section presses against an upper portion of the yoke. A stop limits rotation of the bail bar to a point at which the yoke and handle attain an untilted state. Operating against a lower portion of the yoke, a second mechanism provides a counterbalancing force to normally bias the yoke in the untilted state. No matter where the handle is positioned along its range of motion, when it is tilted by a preset amount, the yoke overcomes the rotational and counterbalancing forces so that a third mechanism causes both the first and second switches to change state.
