This invention relates to a rail tie (also called
a "railway sleeper") and to a railway rail-and-fastening assem-
bly including a rail tie.
BRIEF SUMM~RY OF THE INVENTION
According to one aspect of the invention there is
provided a rail tie made of rolled sheet steel and comprising:
(a) a flat-bottomed trough inverted and having first and
second support surfaces near opposite ends of the tie on which
flanges at the bottoms of first and second railway rails of a
railway track are to stand; (b) first and second ribs pressed
out of the material of the top of the tie and integral with it
on one side of the first and second support surfaces, respec-
tively, and projecting higher than said support surfaces for
locating in each case the edge of one side of the flange on
one of the rails and forming first and second substantially
horizontal passageways substantially perpendicular to the
length of the rail tie, said passageways being closed at the
top and open at least at one end and being suitable for
receiving parts of resilient rail clips for holding the rails
down on the tie; and (c) first and second lugs between the
first and second ribs and on the opposite sides of the support
surfaces, each lug having a part which is higher than said
support surfaces and such that it can lie above and close to
the top of the other side of the flange of one of the rails
and prevent that rail tipping to increase the gauge of the
railway track, and each lug being pressed out of the material
of the top of the tie and integral with it, leaving a hole in
the top of the tie beneath the lug.
According to another aspect of the invention
there is provided a railway rail-and-fastening assembly in a

railway track comprising: a rail tie ma~e of rolled sheet
steel and comprising; (a) a flat-bottomed trough :inverted
and having first and second support surfaces near opposite
ends of the tie, (b) first and second ribs pressed out of
the material of the top of the tie and integral with it on one
side of the first and second support surfaces, respectively,
and projecting higher than said support surfaces and forming
first and second substantially horizontal passageways sub-
stantially perpendicular to the length of the rail tie, said
passageways being closed at the top and open at least at one
end, and (c) first and second lugs between the first and
second ribs and on the opposite sides of the support surfaces,
each lug having a part which is higher than said support
surfaces and each lug being pressed out of the material of
the top of the tie and integral with it, leaving a hole in
the top of the tie beneath the lug, said assembly further
comprising: (d) first and second rails having flanges stand-
ing on said first and second support surfaces, respectively,
each rail having the edge of one side of its flange located
by one of tha ribs and having said part of one of the lugs
lying above and close to the top of the other side of its
flange to prevent the rail tipping to increase the gauge of
the railway track and (e) two resilient rail clips each
having a first part in one of said passageways and a second
part pressing downwardly on the top of said one side of the
flange of one of the rails.
Preferably each said lug, proceeding from its
root to its tip, first extends upwardly at a first angle to
the horizontal and then extends upwardly at a second and
smaller angle to th~ horizontal. The first angle may exceed
60 and the second angle may be less than 30.

The lugs and ribs, preferably are all pressed out
simultaneously or irst one lug and one rib, both in one half
of the tie, are pressed out simultaneously and then the tie is
reversed in position to bring the other half near the pressing
tools and then the other lug and the other rib are pressed out
simultaneously.
BRIEF DESCRIPTION OF THE DRAWING
An example in accordance with the invention is
described below with reference to the accompanying drawing, in
which:-
Figure 1 shows an end view of part of a railwayrail-and-fastening assembly, and
Figure 2 shows a plan view of the same part of the
assembly as Figure 1, and
Figure 3 shows an end view of the complete assembly.
DETAILED DESCRIPTION OF THE DRAWING
Referring to Figures 1 and 2, the illustrated part
of the assembly includes a rail tie 1 made of rolled sheet steel
and in the conventional shape of a flat-bottomed trough inverted.
In each half of the length of the tie there is a projection in
the form of a lug 2 which has been pressed out of the material
of the top 3 of the tie (i.e. the base of the trough~. There is
also in each half of the length of the tie a portion in the form
of a rib 4 which has been pressed out of the material of the top
of the tie. Each rib forms a horizontal passageway 5 closed at
the top, open at both ends, and perpendicular to the length of
the tie.
On each half of the length of the tie rests a rail
6, having a flange 7 at its bottom which stands on a support
surface on the tie, the lug 2 in that half of the
,,
~.~1'7~
tie having~ proceeding from i-ts roo-t -to its -tip, firstly
a par-t 2A ex-tending up -the edge o~ one side of the
flange at an angle of more than 60 to the horizontal
and then a part 2B which lies above and close to that
side of the flange and extends upwardly at an angle of
less than 30 to the horizontal. The passageway 5
in that half of the sleeper is beside the edge of -the
flange on the other side of the flange and is parallel
to the rail.
Two rail clips 8 are used -to hold -the rails
to the tie, each having been made by bending a steel
rod of circular cross-section, a substantially straight
leg 8A of each clip being in a respective one of the
passageways 5, a portion 8B of each clip bearing down-
wardly on the flange of a respective one of the rails
and a portion 8C of each clip bearing downwardly on a
respective fixed surface 9 which, as seen from -the
associated rail, is beyond the associated passageway 5,
the surface 9 being part of the top of the sleeper.
The illustrated lug 2 is integral with the top
of the tie and joined to it on one side of the a~ove-
mentioned support surface and the illustrated rib 4 is
on the opposite side of the support surface and is like-
-wise integral with the top of the tie. It projects
higher than said support surface and locates that edge
of the illustrated rail flange which is remote from the
projection 2 and from the other railO
The illustrated tie can be used with a rail
having a narrower flange, the left-hand edge of which,
in contrast to what is shown in -the drawing, will not
80~
extend to the junction between the parts 2A and 2B of the
projection 2.
Figure 3 shows the ends A and B of the tie and
the two rails, two lugs, two ribs and two clips, in the one
case with the prefix 1 ana in the other case with the pre-
iX 2 before the reference numerals used in Figures 1 and 2.It is to be noted that the lugs 12 and 22 are between the
ribs 14 and 24. They prevent the rails tipping so that the
distance between the tops o~ the rails increases, i.e. the
gauge of the railway track increases.
