Definitions

  • My invention relates to railway car retarders ot the type involving brakebeams located in the trackway and movable into engagement with the wheels of a car for the purpose of retarding the motion vof the car.
  • One feature of my invention is the provis ion of a car retarder of this type in which the brake beam is made up of a series of nonarticulated sections.
  • the accompanying drawing is a plan view showing one rail of a railway track having associated therewith one form of car retarder embodying my invention.
  • the reference character 1 designates a track rail along which cars normally move in the directicn indicated by the arrow. Located on one side of this rail is a brake beam made up of a series of sect-ions 6 6 6, etc.; and located on the other side of the rail is another brake beam made up of a series of sections 7, 7 7
  • Each brake beam section is provided with the usual wheel-engaging shoe 5. Associated with each section of each brake beam are a plurality of springs G, for biasing the section toward the wheels of a car on the track 1. As here shown, one end of each spring is pivotally attached to the brake beam section, and the other end is pivotally fixed to a bar 70 by means of an abutment D. Each bar 70 is rigidly attached to the track ties, which are not shown in the drawing. The axis of each spring (3 is disposed at an angle less than 90 to the track rail, so that longitudinal motion of the brake beam sections in lines parallel with the track rail will result in movement of these sections toward and away from the rail, that is, into closed and open positions of the retarder.
  • the brake beam sections may be moved longitudinally by any suitable means, such, for example, as the mechanism shown and described in application for Letters Patent of the United States, filed by W. C. -McWhirter, April 29, 1927, Serial No.. 187 ,525, which became Patent No. 1,744,833. This operating mechanism is 1928. Serial int'zaisza.
  • the springs are so designed or adjusted that substantially the same pressure is exerted against the carwheel at all points in the section, and for this purposethe pressure per unit of compression of the spring by the car wheels at the creases to a minimum for thespring atthe proaches theleavingjend of the section, theleavmg end is pushed back by the wheels, so
  • a railway car retarder comprising a series of non-articulated brake beam sections located v beside a track rail and movable towards and away from the rail to closed and open positions, and springs for each section for biasing the section towards the rails, the parts being so designed that when the retarder is closed the entering endof each section is farther from the rail than the. leaving end, and said springs being so proportioned and adjusted that when the retarder is closed and a car-passes through the retarder the relatively small compression of the spring at LEMUEL F. How'imn the, entering end of each, section causes sub stantially the same pressure against the wheel as the relatively large compression of the spring at the leaving end.

  • a railway car retarder comprising a series of non-articulated brakebeam' sections located beside a track rail and movable towards and away from the rail to closed and open positions, and springs for'each section tor'biasing the section towards the rails, theparts being so designed that when the retarder is closedthe entering end of each section is farther from the rail than the leaving end, and the pressure per unit ofcompression of the springs being progressively decreased from the entering to the leaving end of each section, so that when. the retarder is closed the pressure exerted on a car wheel is substantially the same at all points in each section. 1' l A.
  • a railway car retarder comprising two series of oppositelydisposed non- ⁇ articulated brake beam sections located one on each side of a trackrail and each section movable toward and away from the rail to closed and open positions, and springs for each section for urging the section towards the rail, the
