  The hydraulic buffer which is contained in a spring

  case in the upper portion of the cradle consists of a;

  Cylinder, piston, piston-rod, controlling plunger, stuffing

  box with gland also 8 running out springs.

  
  

  The cylinder is closed at the rear by the controlling

  plunger and at the front by the stuffing box and gland

  which are locked in the required position by a spring
