Definitions

  • the cast steel crossing piece according to the present invention wherein the running heads or lines comprise a tubular end portion and have at each end a bearing plates, is characterised in that said tubular end portion is truncated in order to provide a clearance under the remaining tubular portion, above said plate, and that this bearing plate is provided with hearing bosses and guiding bosses so dimensioned and disposed as to permit the convenient positioning and welding of connecting members between the aforesaid tubular portions and the Vignoles rails, in perfect alignment with the tubular ends ice of the running heads or lines of the crossing piece, said connecting members being if desired of the type disclosed and illustrated in the applicants French Patent No. 1,432,640.
  • FIGURE 1 is a plane view
  • FIGURE 2 is a longitudinal sectional view taken along the line II-II of FIGURE 1, and
  • FIGURES 3, 4 and 5 are cross-sectional views taken respectively along the lines III-J11, 1V-IV and VV of FIGURE 1.
  • the crossing piece 1 illustrated in the drawing comprises a bearing plate 2 provided with bearing bosses 3 and guiding bosses 4 projecting only very slightly above the top surface of said bearing plate 2; the running lines or heads 5 of the crossing piece have tubular end portions 6 bounded at their outer end by a vertical section 7 of which the external contour corresponds to that of the upper or head portion of a tubular and truncated rail, so as to provide a clearance 8 between said tubular truncated portions 6 and the bearing plate 2.
  • connecting members 9a and 9b Disposed and secured in alignment with each running head or line in, 5b are two connecting members 9a and 9b consisting of steel castings having a tubular cross-sectional contour 10 at their inner end and the contour of a Vignoles rail '11 at their outer ends, of a length sutficient to permit the welding thereof.
  • These connecting members 9a and 9b are aligned by means of the guiding bosses 4 and held in the proper vertical position by the bearing bosses 3 and the faces 3a, and also by means of the spikes provided on the crossties outside the crossing piece.
  • connecting members are welded at 12 to the manganese steel casting, at the ends of the running heads or lines 6, and at 13 to the guiding bosses 4.
