Definitions

  • One of the particular objects of the invention is to provide a diaphragm assembly which permits the use of a low level walkway between cars.
  • Another object is to provide a diaphragm assembly which has the smallest possible movement between interengaging face plates of adjacent cars whereby wear and noise are reduced and the widest possible passageway is left.
  • Another object is to provide a diaphragm assembly in which the tread plates adjust properly for car movements so as to maintain a safe unbuckled walkway surface at all times.
  • Another object is to provide an assembly of simple and inexpensive design which can be easily installed and repaired.
  • Another object is to provide means for keeping the face plates in operating relationship with each other for extremes of movement, especially when mated with standard diaphragms having a considerably higher bottom elevation, and to avoid the chance of one face plate catching against the other in an abnormal position.
