Permanent Way of Railways and the like.
I HUBERT BANKART of Great Winchester Street in the city of London,
Engineer do hereby declare the nature of the said invention for "IMPROVEMENTS
IN METALLIC SLEEPERS AND FASTENINGS FOR THE PERMANENT WAY OF RAILWAYS
AND THE LIKE" to be as follows:-
This sleeper is formed either of a double channel section, or a single channel with
a longitudinal rib on the back.
The main web is preferably slightly arched so as to facilitate the running off of
water and the upper flanges may be cut or bevelled off towards the centre and ends.
Suitable openings in the upper flanges are formed to admit the rails and keys, a
portion of the rail head or foot fitting under a projecting part of the flange.
The chair or block which when secured by the key holds the rail or rails is
suitably shaped according to the section of rail employed and those chairs which
come at the junction of two rails are provided with two pins or projections which
take into corresponding holes in the rails (or the projections could be in the rails
and the holes or recesses in the blocks but the former plan is preferred) and thus
hold rails and sleepers securely together.

I HUBERT BANKART of 8 Pinner's Hall, Great Winchester Street, in the City
of London, Engineer, 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 sleeper is formed either of a double channel section, or a single channel with
a longitudinal rib on the back.
The main web is preferably slightly arched so as to facilitate the running off of
water and the upper flanges may be cut or bevelled off towards the centre and ends.
Suitable openings in the upper flanges are formed to admit the rails and kegs, a
portion of the rail head or foot fitting under a projecting part of the flange.
The chair or block which when secured by the key holds the rail or rails is
suitably shaped according to the section of rail employed and those chairs which
curve at the junction of two rails are provided with two pins or projections which
take into corresponding holes in the rails (or the projections could be in the rails
and the holes or recesses in the blocks but the former plan is preferred) and thus
hold rails and sleepers securely together.
In the accompanying drawings Figure 1 is a longitudinal section of a double
channel sleeper with rails and fastenings mounted in position that at the left side
being taken where a joint occurs. Figure 2 is a cross section (the chair being
omitted) and Figure 3 a plan of Figure 1. Figure 4 shows to an enlarged scale
the mode of securing the rails at joints. Figures 5 and 6 are cross sections of two
forms of sleepers.
A is a sleeper of double channel section having a portion of its upper flanges cut
away in the centre and at both ends to reduce the weight the lower members
being left intact.
་
At a suitable distance apart, 'according to gauge of railway notches or openings,
are formed in the upper flanges for the reception of the rails B, one side of this
notch fitting the rail flange and if necessary abutting against the web of rail. On
the opposite or outside of rail a chair C envelopes the flange and extends underneath
same. This block is held in position by a taper key D which passes through slots
in the flanges of the sleeper and is provided at its smaller end with a serrated edge
to prevent its becoming loose by the vibration of passing trains or other causes.
The chair may be placed on the inside of the rail if preferred.
Where joints occur in the rails the chair C is made larger and extends to the
underside of the rail head it is also provided with pins or lugs C' which fit into
corresponding recesses or holes in the webs of the rails (generally there is one pin
to the end of each rail) and thus secure them against longitudinal movement and
dispense with the necessity for fish plates.
The sleeper A has its horizontal web slightly arched or cambered in cross section
to facilitate the running of water and in some cases is curved longitudinally to
agree with the curvature of the bed on which it is to be placed or the ends are
.turned down.

page_text: Figure 5 is a cross section of the single channel sleeper with the rib E on the
back: otherwise it is similar the double channel or H sleeper which is fully
described herein.
Where the nature of the ground requires it the two under flanges of the double
channel sleeper may be turned outwards as in Figure 6.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. A metallic sleeper for the permanent way of railways having its upper
surface arched or cambered for the purpose of clearing off the water substantially
as specified and shown in Figure 2 of the accompanying drawings.
2. In a metallic sleeper for the permanent way of railways having flanges
extending upwards from the central web or plate the bevelling or cutting away of
said flanges substantially in the manner and for the purpose specified and shown
in the accompanying drawings.
3. The method of preventing excessive longitudinal movement of the rails
consisting in the employment where two rails meet of pins or projections such
as C¹ connected together and engaging with both rails substantially as specified.
4. A metallic railway sleeper of double channel or H section or of single
channel with a rib such as E on the back substantially as specified.
5. A metallic sleeper of doube or single channel section the depending flanges G
whereof are turned outwards from each other substantially as specified and shown
in Figure 6 of the accompanying drawings.
