Definitions

  • This invention relates to brake operating means for railway trains.
  • An object of this invention is the provision of automatically actuated means for operating the brakes of a car when its draft gear is subjected to strains exceeding predetermined value.
  • Fig. l is a longitudinal section of an embodiment of the invention.
  • Fig. 2 is a view similar to Fig. l in another position of the parts.
  • the draft gear for each car comprises two rods A extending longitudinally of the car frame, each rod being substantially one-half the length of the car and each rod being provided with a coupler head a.
  • Each rod A is provided with a pair of collars a and (7. against which abut followers B, slidably mounted on the rod A.
  • Springs C are interposed between the followers B and transmit strains from the rods A to the car structure in the well-known manner through abutments provided on the car frame for that purpose.
  • each rod A has a collar a rigidly mounted thereon and followers D are slidably moimted on the rods A between the collar a and abutments a provided at the inner end of each rod.
  • a spring E is arranged between the followers D and is of higher resistance than the springs C.
  • Guide rods F extend through each collar a and the followers D, these riods being provided with nuts so that outward pull on either rod A is transmitted through the followers D, rods F and spring E to the remaining rod A.
  • Levers G are pivoted at one end to the collars a and are pivotally connected at their other end by a pin 9 carrying a roller g thus forming a toggle for moving the roller g upon relative movement of the collars 01.
  • a bell crank lever H is pivotally supported on the car frame by a pin h and has its arm 71. extending into 00 the-path of the roller The arm 71. of the lever H is provided with a shoulder which is engaged by one arm of the lever K, also supported by the under frame of the car.
  • This lever K is attached to a valve T controlling a branch 05 conduit 2 leading from the air brake line L and discharging to the atmosphere.
  • a link M is pivotedto the arm k and is provided at its free end with a slot m through which projects a pin k carried by the lever K. 1
