Description

ADAPTER PLATE FOR AUTOMATIC TEST CONNECTOR FOR PIPELINE MAINSTREAM AB FIELD OF THE INVENTION This invention relates generally to a portion of pipe bracket of a brake valve control device for rail cars, that pipe bracket has a plurality of test ports for direct access to the fluid lines and determining their pressures, and more particularly the invention relates to an adapter plate used with the test ports of that pipe bracket to provide at least one upper and lower access for the automatic individual car brake tester. BACKGROUND OF THE INVENTION Wagon brake control valves include a portion of a pipe bracket having a service portion and an emergency portion mounted on opposite sides or faces of the pipe bracket. Those brake control valve assemblies of the prior art are shown diagrammatically in Figure 1.

Typically the back side of the pipe bracket portion has a number of locations for connecting the pipe bracket portion to the wagon pipe. Those rear locations will generally include the connections to the brake line, the brake cylinder retainer valve, the brake cylinder, the emergency tank and the auxiliary tank. Those pipe bracket connections to pneumatic tubing allow the pipe bracket to provide the necessary communication of fluid pressures to both the service and emergency portions of the brake control valve as well as the brake cylinder and reservoirs. Most type AB pipe brackets only have connections to the pipe lines on the rear surface. However, since it is sometimes necessary to enter the fluid lines in order to obtain fluid pressure measurements inside the pipeline, that access to the fluid is often very difficult depending on the placement of the brake control valve in the loading cart. In addition, the connections between the pipe bracket and the car pipe should be separated to allow pressure monitoring. Recent modifications to the brake pipe bracket AB have provided direct access to the fluid passages through the front lads of the pipe bracket on the brake control valve of the car. This modification eliminates the need to have access to the rear side of the car's brake control valve. Front-side test ports provide access to the brake line, brake cylinder, emergency tank and auxiliary tank. Providing these test ports on the front side of the pipe bracket allows testing of fluid pressures within the pipe bracket without having to remove the rail brake control valve or service portion from the emergency portion. from the pipe bracket portion. This pipe bracket, braking method has been described in the US patent application no. series 08 / 547,929, which is assigned to estinghouse Air Brake Company. The automated individual car brake tester will have been described in the US patent application no. series 08 / 365,8715, and is also assigned to Westinghouse Air Brake Company. The test ports on the front side of the pipe clamp provide an important improvement over the old pipe brackets by providing access to the passages in the pipe bracket without having to disconnect the fluid lines normally connected to the back side of the pipe. the pipe bracket portion. However, this modification only provides lateral access to the pipe bracket portion. Unfortunately, there may be cases in which car builders can not use side access, which has test ports arranged vertically, and may prefer or require higher or lower access.

SUMMARY OF THE INVENTION The present invention provides a dockable test connector adapter plate with test ports I positioned vertically on a front side of a pipe bracket portion of a freight or wagon control valve of a freight vehicle. rail and with a test receiver of a portable automatic individual car brake tester. That pipe bracket has a plurality of steps to provide for fluid communication between those test ports in the pipe bracket portion and the brake pipe, the brake cylinder, the emergency tank and the auxiliary tank, respectively. That test corrector adapter plate consists essentially of a first member provided with access ports that are vertically arranged and can be coupled with those test ports on that front side of the pipe bracket portion to have access to the passages in such a way that the pipe bracket portion to communicate the fluid pressure with the brake pipe, the brake cylinder, the emergency tank and the auxiliary tank, respectively. These ports of access to that first member are in fluid communication with the respective steps within the adaptive lacquer of the test connector to communicate with the fluid pressure.

A second member of that test connector adapter plate is a distributor having access ports in fluid communication by means of respective passages within the test connector adapter plate to the access ports on the first member of that adapter plate of test connector for communicating the fluid pressure in the brake line, the brake cylinder, the emergency tank and the auxiliary tank, respectively, and coupled with such a test receiver of the automatic individual car brake carrier. That distributor of the second member of the test connector adapter plate is arranged to provide access ports in the second member on the axis perpendicular to that of the access ports on the first member of the first adapter connector plate for testing. providing at least one upper and one lower access for the test receiver of the automated single carriage brake carrier. OBJECTS OF THE INVENTION It is therefore one of the primary objects of the present invention to provide a test connector adapter plate for the modified AB pipe bracket which requires additional shaping of the pipe bracket. Another object of the present invention is that of proportional- an adaptive plate of test connectsr for the modified AB pipe bracket which is installed in a simple manner. Still another object of the present invention is to provide a test connector adapter plate for the pipe bracket. Modified AB that included a cover plate for the upper portion of the access ports to the distributor when the bottom access is used and a cover plate for the lower portion of the entry ports, to the district when the upper access is used. .
