  • FIGS- RAIL JOINTS This invention relates to rail joints and rail systems.
  • Hitherto rails have been welded or connected by fish plates connected to the sides of the rails. Welding can cause distortion and requires expensive equipment to align and assemble the track and fish plates produce localized changes in the cross-section of the rails.
  • a rail system comprises interconnected lengths of rails upon which a vehicle wheel or roller may run and a joint-piece of similar cross-section to the rails located between the aligned adjacent ends of successive lengths of rail
  • the joint-piece comprises a wedgeshaped element having a wheel or roller bearing surface aligned with corresponding surfaces on the rails
  • the rail ends are wedge-shaped to co-operate with the joint-piece
  • engagement means are provided within the cross-section of the joint-piece and rails whereby the joint-piece is engaged with the rails so as to transmit at least part of the vehicle weight from the joint-piece to the rails.
  • the rails are preferably circular in section and may be tubular.
  • the engagement means may comprise a cylindrical member projecting from each end of the wedge-shaped element for engagement withthe tubular rails.
  • a similar projecting cylindrical member may also be provided projecting from the end of each rail for engaging the joint-piece.
  • Another aspect of the invention provides a method of assembling a rail track comprising aligning the adjacent ends of successive lengths of rail supported upon a load bearing surface to leave a wedge-shaped gap when viewed in plan, inserting a wedge-shaped joint-piece in a direction substantially parallel to the said surface and locking the joint-piece toprevent movement in that direction.
  • FIG. 1 is a plan view of a joint-piece located between two rail ends;
  • FIG. 2 is a side view in a direction of arrow A shown in FIG. I and,
  • FIG. 3 is an end view of a joint-piece shown in FIG. 1 partially in cross-section;
  • the embodiment of the invention is applicable to passenger conveyors of the kind in which passengercarrying platforms are each provided with rollers running upon spaced-apart rails.
  • FIG. 1 illustrates a joint-piece 1 comprising a wedge shaped element 2 which is tubular.
  • a mounting pin 3 is welded to the tubular element and extends from it transversely at the tapered side of the wedge-shaped tube and is secured with a nut and spring washer 3a within a boss 4 forming part of a supporting bracket 5, the supporting bracket 5 having a pair of holes in a base portion for securing it to a load-bearing member or surface.
  • Similar brackets 50 and 5b are provided, one on each side of the bracket 5, and are similarly secured, respectively, to portions of tubular rail lengths 6a and 6b.
  • the rail lengths have wedge-shaped ends 7 and 8, respectively, shaped corresponding to the ends of the jointpiece 1, gaps 9 and 10 existing between the rail ends and the joint-piece.
  • Tubular cylindrical projecting members 15a and 15b are provided, one at each end of the joint-piece, and are secured co-axially with it so as to project from the joint-piece sothat substantially half the area of the projecting cylinder end remains within the volume enclosed by the wedge-shaped tubular joint-piece and engaged into the adjacent rail ends 7 and 8 (see FIG. 1).
  • Similar second cylindrical tubular projecting members 16a and 16b are secured co-axially within rail ends 7 and 8 and, similarly, project from the rail ends into the joint-piece.
  • tubular rail lengths are mounted by means of the brackets and 5b in acurate co-axial alignment.
  • a pre-assembled joint-piece 1 comprising a wedgeshaped tubular element, tubular members 15a and 15b, and bracket secured together by means of a pin 3 and nut and washer 3a, is slid laterally into position to joint the rail lengths.
  • the lateral "sliding is made possible by the wedge shape of the element, as described, but this case of assembly doesnot mean that no support is provided by the joint-piece l to the rail ends 7 and 8.
  • the wedge-shape itself serves as some support if the corresponding rail ends are deflected to close the gaps 9 and 10 to bear upon the wedge-shaped element 2. More positive support, however, is provided by the cylindrical tubular members 15a and 15b and 16a and 16b.
  • a rail system having interconnected lengths of tubular rails and a joint between adjacent ends of successive lengths of rail comprising:
  • a joint element between aligned adjacent ends said element having wedge shaped ends with oblique cuts and cylindrical projections complementary to those of the rail ends so that the joint element can be inserted without longitudinal displacement of the rail.
