PROVISIONAL SPECIFICATION.
Improvements in or relating to Rails for Rail and Tramways.
We, ROBERT CORKLING, Gentleman, of 182, Regents Park Road, in the County
of Middlesex, and JEROME PHILO OSTROM, Gentleman, of 150, Finborough Road,
in the County of Middlesex, do hereby declare the nature of this invention
to be as follows:-
This invention relates to rails for use in rail- and tram-ways, and may be
carried out in the following manner: —
The upper portion comprises a running or track rail with a suitable head or
top to receive the wheels of the vehicles and a lower rail which would take the
place of the usual chairs and may be secured in any desired way to the sleepers
or other form of the permanent way or road-bed. The track-rail is provided with
a central web which fits into a suitable channel formed in or upon the lower
rail, cross bolts or other suitable fastenings passing through all three webs or
flanges and securing them together. The lower rail may be provided with two
webs or flanges of length equal to that of the rail so as to form between them
the channel in which the web or flange of the upper rail fits, or a series of jaws,
may be formed upon the lower rail for the same purpose.
The upper rail may be provided with longitudinal channels or recesses to
receive the upper edges of the flanges of the lower rail.
The above described arrangements may be reversed, the single flange or web
being upon the lower rail and two flanges or webs being upon the upper or track
rail.
The ends of either or both the rails may be bevelled or intercalated to minimise
jolting at the joints.
The various flanges may bear upon their opposing rails for the whole or any
portion of their length. The holes through which the bolts or other fastenings
pass may be elongated in the direction of the length of the rail to accommodate
expansion and contraction and similar provision may be made if desired in a
vertical direction.
By means of this invention the upper or track rail can be removed without dis-
turbing the lower rail or sleepers etc., and the ordinary chairs, fish-plates, etc.,
are avoided. The lower rail does not require to be made of steel.

We, ROBERT CORKLING, Gentleman, of 182, Regents Park Road, in the County
Middlesex, and JEROME PHILO OSTROM, Gentleman, of 150, Finborough Road,
[Price 8d.]

page_text: in the County of Middlesex, 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;
This invention relates to rails for use in rail and tram-ways, and may be
carried out in the following manner:
The upper portion comprises a running or track rail with a suitable head or
top to receive the wheels of the vehicles and a lower rail which would take the
place of the usual chairs and may be secured in any desired way to the sleepers
or other form of the permanent way or road-bed. The track-rail is provided with
a central web which fits into a suitable channel formed in or upon the lower
rail cross bolts or other suitable fastenings passing through all three webs or
flanges and securing them together. The lower rail may be provided with two
webs or flanges of length equal to that of the rail so as to form between them
the channel in which the web or flange of the upper rail fits, or a series of jaws
may be formed upon the lower rails for the same purpose.
The upper rail may be provided with longitudinal channels or recesses to
receive the upper edges of the flanges of the lower rail.
The above described arrangements may be reversed the single flange or web
being upon the lower rail and two flanges or webs being upon the upper or track
rail.
The ends of either or both the rails may be bevelled or intercalated to minimise
jolting at the joints.
The accompanying drawings illustrate this invention as carried out for rail-
way purposes.
Figure 1 is a vertical section of one construction of rail according to this
invention,
Fig. 2 is a vertical section of a modified form of the same, and
Fig. 3 is a broken side elevation of the form of rail illustrated in Figure 2.
Figs. 4 and 5 show in plan two forms of bevelled joints,
Like letters indicate like parts throughout the drawings.
The upper or running rail A is shown in Fig. 1 as having two downwardly
directed webs A¹ which engage with an upwardly directed web B¹ of the lower
rail or carriage B spiked or bolted down to the sleepers C. The lower rail is
provided with longitudinal channels B2 one on either side of the web 13 which
receive the ends of the webs A¹ when the rail A is placed in position on the
rail B; the two rails are secured together by means of bolts or other fastenings D.
If preferred the upper rail may be provided with one web A¹ only engaging
with two webs B' on the lower rail B as shown in Fig. 2. In this case the
channels B2 would be formed in the upper rail as at A².
In both cases the single central web may be tapered the channel formed
between the two other webs with which it engages being also tapered as shown in
Fig. 1 in order that the lateral rigidity of the rail may be increased; also the
outside ends of the two webs may be tapered or bevelled and the channels to
receive them correspondingly tapered or bevelled for the same purpose. This
bevelling also serves to facilitate the entrance of the webs into the channels when
"placing" the upper rail. If however preferred both constructions of rail may
be made with webs of rectangular cross-section as shown in Fig. 2 and the
channels may or may not be used with either form of web.
The upper and lower rails which are of the same length are preferably jointed
as shown in Fig. 3 so that the joint of one rail comes at or about the middle of
the length of the other thus dispensing with the use of "fish plates" and decreas-
ing the amount of spring between the ends of the different sections of rail.
To further decrease this spring the sleepers may be arranged to come under
the joints as shown or the rails may be carried by longitudinal sleepers.
The jolting usually experienced in passing over a joint in the rails may also
be decreased by bevelling the ends of the rails either as shown in Fig. 4 or Fig. 5

page_text: so that the wheel of the passing vehicle may be brought gradually over the space
between the two lengths of rail.
The holes through which the bolts or other fastenings D pass and also those
through which the fastenings to the sleepers pass may be slotted to permit of
the expansion of the rails in the direction of their length.
It will be understood that the one rail need not be made to bear upon the other
throughout the whole of its length but that the webs on the rail, bearing the
double webs may be arranged as a series of pairs of jaws engaging the web of
the second rail.
By means of this invention the upper or track rail can be renewed without dis-
turbing the lower rail or sleepers, etc., and the ordinary chairs, fish-plates, etc.,
are avoided. The lower rail does not require to be made of steel.
Having now particularly described and ascertained the nature of our said iu-
vention and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination with an upper running or track rail having a downwardly
directed web of a lower rail or carriage having two upwardly directed webs sub-
stantially as and for the purpose described and illustrated in Figure 2 of the
accompanying drawings.
2. In a rail of the kind described a longitudinal channel or recess such as formed
on the under side of upper rail or on the upper side of the lower rail for the
purpose described.
3. A rail constructed substantially as described or illustrated in Figure 1,
Figures 2 or Figure 3 of the accompanying drawings.
