EMPTY/LOAD SENSOR MECHANISM FOR CONTROLLED VEHICLE BRAKING

摘要

An empty/load mechanism for controlling the brake pressure on a railroad car is mounted inboard on the web of the car body side sill having a lower flange. A pivotable sensing arm reaches around the side sill flange and has a horizontal contact shaft at its free end for contact with the upper surface of a truck side frame for operating the mechanism in response to the distance between the car body and the truck.
