Definitions

  • the wear plate is positioned in a recess formed in the bottom surface of the coupler shank and is rigidly fastened thereto so as to be seated in the recess to equally distribute the coupler weight and to prevent buckling of the wear plate which can result in fracture of the fasteners.
  • the coupler shank side surfaces have formed on the lower portion thereof a radius that terminates substantially tangent to the wearing surface of the wear plate to insure a smooth nongouging operation of the coupler during rotation.
  • This invention relates generally to railroad rotary couplers and particularly to a new and improved rotary dump coupler with a novel wear plate attached to the bottom surface of a rotary coupler.
  • a wear plate for the lower coupler shank area is often provided.
  • Such prior art wear plates have taken the form of the wear plate shown in FIGS. 1 and 2 of the drawings and consist of a generally U-shaped plate I which is prebent and heat treated subsequent to being welded to the lower side surfaces 12 of the coupler shank- 14.
  • the wear plate thusly formed attempts to protect the lower side surfaces 12 as well as the bottom surface 16 of the coupler shank during rotation and horizontal movement of the coupler on the coupler carrier (not shown in the drawings).
  • the present invention provides a new and improved wear plate which is contained in a recess formed on the bottom surface only of the coupler shank thereby eliminating buckling of the wear plate and fracture of the welds.
  • the coupler shank is provided with a pair of radii on the lower portion of the shank side surfaces that terminate substantially tangent to the wearing surface of the wear plate to insure that the coupler carrier will not be gouged during dumping ofthe car.
  • Another object of the invention is to provide a new and improved rotary coupler shank which contains a wear plate that is not subject to buckling and fracture of its welded joints.
  • Yet another object of the invention is to provide an improved coupler shank having a novel wear plate on the lower surface that does not gouge the coupler carrier or prevent a smooth rolling action during dumping of the car.
  • FIG. I is a side elevational view of a coupler showing a prior art type of wear plate installed thereon;
  • FIG. 2 is an enlarged cross sectional view taken along line 2-2 of FIG. 1;
  • FIG. 3 is a side elevational view of the present invention installed on a railroad coupler
  • FIG. 4! is an enlarged cross sectional view taken along line 4-4 of FIG. 3.
  • the present invention which comprises a substantially rigid rectangular shaped flat wear plate 20 having a wearing surface 21 formed on the bottom surface thereof.
  • the wear plate 20 is positioned within an elongated recess 22 formed in the bottom surface 24 of the coupler shank 26.
  • the wear plate 20 is rigidly fastened to the coupler shank 26 by means of a welded joint 28 which may be continuous or intermittent on each side of the recess 22 but not on the transverse sides thereof.
  • the wear plate 20 is substantially flat and the recess 22 has the same contour, the wear plate is positioned in the recess 22 in such a manner that it always seats in the recess in contact with the coupler shank to equally distribute the coupler weight throughout a major portion of the wear plate area. This prevents buckling of the wear plate whenever the plate rubs or impacts on the coupler carrier during horizontal and rotary motion of the coupler. As a result, the before mentioned fractures of the wear plate weld are eliminated thereby providing an improved coupler wear plate.
  • the wear plate of the invention provides a replaceable wearing surface only on the bottom surface of the coupler shank and not on a portion of the sides as was the practice with the prior art type U-shaped wear plate. It is apparent that the use of the wear plate of the invention also eliminates the costly and difficult control required of the shape of the wear plate and the shape of the mating coupler shank.
  • the side surfaces 30 of the coupler shank 26 have formed on the lower portion thereof a radius 31 which terminates substantially tangent to the wearing surface 21 of the wear plate 20 to prevent gouging of the coupler carrier and to permit a smooth rolling action of the coupler during the dumping of the railroad car.
  • a rotary coupler of the type having a coupler shank bottom surface in rubbing contact with a coupler carrier and a pair of side surfaces, the improvement comprising:
  • the bottom shank surface having formed therein an elongated recess
  • each side surface having formed on the lower portion thereof a radius terminating and said elongated recess;
  • a rigid wear plate having a Brinell hardness ranging from 350 to 450, positioned within said recess so that its wearing surface is substantially tangent to the side surfaces for a smooth, nongouging operation during rotation of the coupler;
  • a continuous welded joint formed on each side of said recess, to rigidly fasten said wear plate within said recess so that said wear plate is seated in said recess in contact with the coupler shank throughout its area to equally distribute the coupler weight over a major portion of said wear plate area and to prevent failure of said welded joints caused by buckling of said wear plate during horizontal and rotary motion of the coupler.
