A pipe bracket portion of a freight brake control valve having an improved filter arrangement. The pipe bracket portion has a first side with a service portion and an emergency portion mounted thereto. The pipe bracket portion has a second side with a brake pipe, a brake cylinder, a emergency reservoir and an auxiliary reservoir thereto. The pipe bracket portion is provided with a cavity designed for containing a generally cylindrical filter therein. A retaining nut secures the filter in the cavity and provides a seal between the outer circumference of one end of the cylindrical filter and the pipe bracket portion. A first cavity portion and a second cavity portion are thus formed within the cavity in which the first cavity portion houses the cylindrical filter, and the second cavity portion has at least one radial port for delivering air. The retaining nut has a throughbore to permit air flow from the first cavity portion to the second cavity portion and has one or more spaced raised portions extending into the second cavity portion to provide radial airflow from the second cavity portion to the radial ports.

An access plate mounted between the pipe bracket portion and either the service portion or the emergency portion of a railway freight brake control valve. Passageways are provided through the access plate, each passageway terminating in a respective access port along an end of the access plate. Openings extend through opposed sides of the access plate, intersecting respective access plate passageways. The openings on each side are sized and positioned to sealingly align with openings of the pipe bracket portion and either the emergency portion or the service portion. The openings on the pipe bracket portion, emergency portion and service portion connect to passageways communicating to the brake pipe, the brake cylinder retaining valve, the brake cylinder, the emergency reservoir and the auxiliary reservoir. A housing may be attached to the pipe bracket portion to connect to the access ports, such housing preferably having a valve means for preventing the escape of fluid pressure therefrom. An adaptor may engage with the housing, opening the valve means and allowing the fluid under pressure to enter the adaptor.

The brake cylinder comprises a cylinder body comprising an annular flange and a non-pressure head. The annular flange of the cylinder body defines a plurality of openings. The non-pressure head has an annular flange and a head portion extending from the annular flange. The annular flange of the non-pressure head has a plurality of bosses and a plurality of openings corresponding to and aligned with the plurality of openings in the annular flange of the cylinder body. At least one vent is positioned in one of the plurality of bosses. The cylinder body and the non-pressure head are secured to each other at the respective flanges. The vent is positioned in the boss disposed opposite a mounting portion so that when the brake cylinder is mounted to a railway vehicle, the vent is oriented in a bottom position on the cylinder body with respect to a ground surface.

A dual valve fitting enables pressure within a housing to be quickly measured. The fitting includes first and second valve bodies. The first body defines a passage between its threaded and protuberant ends. In the passage, a first valve atop a valve stem features a poppet head that is seatable against an outer valve seat. A first biasing mechanism compels the poppet head against the outer valve seat so that the first valve is normally closed. The second body defines a bore between its upper and lower threaded ends which communicates with the passage. The upper threaded end connects with the threaded end of the first body whereas the lower threaded end is designed to screw into a threaded bore of the housing. In the bore, a second valve features a retainer whose top defines a recess that retains a seal element that is seatable against an inner valve seat. A second biasing mechanism acts upon the retainer so that the seal element therein seats against the inner valve seat thereby rendering the second valve normally closed.

A pipe bracket for use in a freight brake control valve on a railway freight vehicle. A service portion and an emergency portion are mounted to a first pipe bracket side directed opposite to the first pipe bracket side. Piping to a brake pipe, a brake cylinder, an emergency reservoir and an auxiliary reservoir are connected to a second side of the pipe bracket. A plurality of passageways are provided through the pipe bracket portion for providing fluid communication from the brake pipe, the brake cylinder, the emergency reservoir, and the auxiliary reservoir to the service portion and the emergency portion. One or more and preferably four access ports connect to one or more and preferably each of the passageways. Preferably, the access ports are provided on the first side of the pipe bracket portion. A housing having one or more channels, each corresponding to an access port is engaged to the pipe bracket portion so that fluid pressure at the access ports can be transmitted to the housing.

The present invention is a valve system for exhausting air from a brakepipe in a remote portion of a train. It has a pressure containment structure having a cylindrical bore and a piston mounted in the bore. A first valve chamber is on one side of the piston and a second valve chamber on a second side. A diaphragm seals between piston and bore, the diaphragm having an annular fold for permitting movement of the piston within the bore. The system has a first brakepipe pressure passageway for conveying air from the brakepipe to the first valve chamber and a control pressure connection for conveying air from a control chamber to the second valve chamber. A biasing means is provided for urging the piston toward the first valve chamber. A brakepipe exhaust valve connected to the piston is closed when the piston is moved toward the first valve chamber and opened when the piston is moved toward the second valve chamber so that when the pressure in the control chamber is reduced the brakepipe exhaust valve is opened and air is vented from the brakepipe. An annular sleeve is attached to the pressure containment structure and protrudes into the fold of the diaphragm to prevent the diaphragm from inverting if the pressure in the brakepipe drops below the pressure in the control chamber when the piston is positioned toward the first valve chamber.

A constant tensioning device in the form of an elastic member interposed in the handbrake chain between a railway car handwheel and a handbrake lever of the railway car brake apparatus for maintaining tension in the handbrake chain in accordance with the applied handbrake force, irrespective of such shifting of the railway car relative to its truck, as would otherwise cause slack to develop in the handbrake chain and thereby cause an undesired loss of handbrake force.

A nozzle assembly allows a metered dose of lubricant to be dispensed. It comprises a housing and a piston assembly. The housing defines a piston bore, a stem bore and a spout, all of which axially aligned. It also defines a lubricant passage, an air inlet, and a channel linked to the inlet. Connectable to a source of lubricant, the passage communicates with the stem bore. Connectable to a source of air, the inlet communicates with the stem bore at a position between the passage and spout. The piston assembly has a piston with stem and a spring. The piston lies in the piston bore, its back communicating with the channel. The protrudent end of the stem protrudes into the stem bore and has a groove defined about its circumference. The spring biases the piston assembly into a charge position wherein the groove aligns with the passage. This enables the groove to fill with lubricant.
