摘要： A hopper car door locking mechanism includes a rotatable latch member which includes a keeper receiving portion. The latch member also includes a positioning portion providing stops which are engaged by a rotatable locking pawl in the closed position of the hopper car door. The rotatable locking pawl includes a cam device which is pivoted in response to reciprocating movement of a rod having a suitable cam surface. The rod also includes a stop device which with the rotatable latch member provides a second stop which therefore provides for double locking of the door.

摘要： A railway hopper car includes laterally positioned bottom dump discharge openings and doors which are locked in a closed position by a latching mechanism actuated from a ground-mounted trip lever. After the car has been dumped it is moved adjacent to a ground-mounted cam which is engaged by cam followers on the doors thereby swinging the doors again to the closed position.

摘要： A static switching apparatus for a track vehicle includes a main line track and a switch track which at a switching junction both include a conventional track rail and a specially constructed rail. A switching cam including cam faces is positioned at the junction and includes straight and curved cam surfaces which are selectively engaged by cam followers supported on the vehicle to provide for steering of the vehicle. The cam followers are lowered and raised vertically by fluid extensible devices which also move them in an orbital path into cam surface engagement.

摘要： The side discharge doors of a railway hopper car are maintained in a closed and locked position by a rotatable latch element which is engaged by a stop and lock member. The stop and lock member is connected to a linkage rigging arrangement which is moved by a ground actuated operating and tripping mechanism. The tripping mechanism includes a cam actuated arm which by linkage means transmits vertical movement to horizontal movement of the linkage rigging which actuates the latch and locking members of the doors.
