Automatic test connector adapter plate for AB pipe bracket

A test connector adapter plate engagable with vertically disposed test ports on a front side of a pipe bracket portion of a freight brake control valve of a railway freight vehicle and with a test receiver of a portable automated single car brake tester, said pipe bracket portion having a plurality of passageways for providing fluid communication between said test ports and brake pipe, brake cylinder, emergency reservoir and auxiliary reservoir, respectively, said test connector adapter plate consisting essentially of:

• a. a first member provided with access ports which are vertically disposed and engagable with said vertically disposed test ports on said front side of said pipe bracket portion for accessing said passageways in said pipe bracket portion for communicating fluid pressure with said brake pipe, said brake cylinder, said emergency reservoir and said auxiliary reservoir, respectively;
• b. said access ports on said first member of said test connector adapter plate being in fluid connection with respective passageways within said test connector adapter plate for communicating fluid pressure;
• c. a second member of said test connector adapter plate being a manifold having access ports in fluid communication via said respective passageways within said test connector adapter plate and with said access ports on said first member of said test connector adapter plate for communicating fluid pressure from said brake pipe, said brake cylinder, said emergency reservoir and said auxiliary reservoir, respectively, and engagable with said test receiver of said portable automated single car brake tester,
• d. said manifold of said second member of said test connector adapter plate is disposed to provide said access ports on said second member on an axis perpendicular to that of said access ports on said first member of said test connector adapter plate so as to provide at least one of a top access and a bottom access for said test receiver of said portable automated single car brake tester.
