  • Coupler unit wear pad assembly for railroad equipment
    Patent number: 5174457
    Abstract: A novel wear pad assembly (22) allows worn coupler carrier wear pads of locomotives and train cars to be easily removed, replaced or reversed. A holder-tray (30) attached to the coupler housing (14) of a train car or locomotive receives a removable wear pad (32). A holder plate (34) holds removable wear pad (32) in place within holder-tray (30). When removable wear pad (32) becomes worn and must be replaced, holder plate (34) is removed, worn pad (32) is replaced with a new removable wear pad (32), and holder plate (34) is put back in place. Coupler (16) is not removed from coupler housing (14) during the replacement process. Removable wear pad (32) may be made of materials that increase lubrication and decrease friction between coupler (16) and removable wear pad (32).
