Abstract
An improved guide bracket for doors on railroad cars which reduces or eliminates wear of the guide bracket and the guide member of the lower door track of the railroad car. The improved guide bracket includes a J-shaped plate and a tubular plastic wear collar or member mounted on the plate. The wear collar engages the inner surface of the guide member of the lower door track and prevents wear of the guide member when the door moves or vibrates. When worn, the wear collar may be separately replaced without replacing the entire J-plate and or track.
Claims19
A guide bracket for a door on a railroad car, said railroad car having a flame and a lower door track connected to the frame, said track having a substantially horizontally disposed bearing member for supporting the door and a substantially vertically disposed guide member having an inner surface engaged by said guide bracket for guiding the movement of the door on the track and preventing the door from coming off the track, said guide bracket comprising:
- a plate having connected inner and outer walls, said outer wall adapted to be attached to said door, and said inner wall adapted to be aligned with said guide member;
- and
- a plastic wear member attached to the inner wall and aligned with said guide member,
- whereby the wear member adapted to engage the inner surface of the guide member when the door moves or vibrates to reduce wear on the guide member.
A guide bracket for a door on a railroad car, said guide bracket adapted to be mounted adjacent to a lower end of the door to guide the lower end of the door along a lower door track attached to the car during opening and closing of the door, said track including a substantially vertically extending guide member, said guide bracket comprising:
- an outer wall adapted to be mounted on the door;
- an inner wall adapted to be aligned with the guide member, said inner wall including a base which defines a shoulder, and a neck extending from the base and having a smaller dimension than the base;
- and
- a plastic wear collar mounted on the neck and supported by the shoulder, said wear collar including an engaging wall adapted to be aligned with and to engage the guide member to reduce the wear on the guide member as the door moves or vibrates, and said wear collar including at least two locking walls connected to the engaging wall and adapted to maintain the wear collar on the neck.
In a car having a frame, a lower door track connected to the frame, and a door movably mounted on said lower door track, said lower door track having a substantially horizontally disposed bearing member for supporting the door and a substantially vertically disposed guide member for guiding the movement of the door, a guide bracket mounted on the door for engaging the guide member along its inner surface to guide the door and to prevent the door from disengaging the lower door track, the improvement being in the guide bracket which comprises:
- a plate having connected inner and outer walls, said outer wall adapted to be attached to said door, said inner wall adapted to be aligned with said guide member, and
- a plastic wear collar attached to the inner wall and aligned with said guide member.
