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).

Abstract: A skate board including a body and a pair of trucks located fore and aft with a friction brake pivotally mounted with respect to the board body to bring a pair of brake shoes into engagement with each of two rear wheels of the rear truck. An operator arm extends from the truck upward above the level of the board whereby the foot of the rider may be used to pivot the brake shoes into engagement with one or the other or both of the truck wheels. The brake arm and shoe assembly is pivotal about a transverse horizontal axis to bring the shoes into engagement with the surface of the wheels and likewise is pivotal around a longitudinal axis to selectively engage one or the other of the two wheels for steering. The operator arm may be operated by either the rear foot of the rider or by his hand in certain cases when the rider is crouched upon the board.
