An Improvement in Railway and Tramway Rails.
I, OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
For certain purposes, railway and tramway rails are constructed in the following
manner; the head and web of the rail are rolled in the usual lengths, and at the
ends of each length, and at intervals between the ends, discontinuous flanged
supports or pedestals are attached to the rail web, these pedestals being either
separate steel castings or short lengths cut from rolled bars, electrically or other-
wise welded to the rail web so as become integral with the rail. This invention
relates to such a construction of rails of the kind referred to and of their pedestals
or supports as to give increased rigidity and strength to the rail between the
supports and to ensure a more sound and strong weld of the support to the rail. For
this purpose, the rail is rolled with a bend or prominence projecting at the lower
edge of the web on either side thereof or preferably on both sides, and the upper
edge of the piece that is to form the support is preferably, but not necessarily,
beaded in a corresponding manner. There is thus provided at the place of the
weld additional thickness of metal including the beads, whereby the junction of
the two pieces is ensured and strengthened while between the supports the edge of
the web is stiffened by the beading.
Fig. 1 of the accompanying drawings is a side view of part of a tramway rail
with supports or pedestals S at its ends and others s at intervals, and Fig. 2 is a
transverse section on X. Fig. 3 is a section shewing the rail R and pedestal S
separately cach with a bead B B' at the edge of its web, so that, when the two
edges are brought together to be welded, their beads furnish additional metal to
form a strong weld at W; moreover the bead 13 at the edge of the rail web gives
the rail additional stiffness between the discontinuous supports Ss. The rail head
and the pedestal may be of various forms examples of which are shewn in Figs. 4
and 5. Also as shewn in Fig. 6, the rail web instead of being merely beaded, may
be formed with a flange to be welded at its edges to beads on the pedestal, so that.
when the parts are united, the rail and pedestal are made integral as shewn in
Fig. 7. When the rail has double webs the beads may be formed on the outer
side only of each rail web, and also on the outside of each web of the pedestal,
which may have its base in one piece with its webs as shewn in Fig. 8, or which
may consist of separate angle pieces as shown in Fig. 9. When the double webbed
rail has a bend on each side of each web, it is rolled first as shewn by Fig. 10 with
the webs curved away so that the beads can pass through the rolls, the webs being
afterwards straightened as indicated by the dotted lines.
Although, in the drawings, the webs of the pedestals are shewn beaded, they
may have plain edges without beads, and, as the pedestals are comparatively short
pieces, the whole web may be thickened if required without involving great
expenditure of metal.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what 1
claim is :-
The construction of rails and of discontinuous pedestals or supports to be welded
thereto with beads or prominences on the edges of the rail web with or without.
