FREDERICK CHARLES WINBY of Palace Chambers St Stephens in the City of
Westminster "IMPROVEMENTS IN RAILWAY RAILS AND IN FISH JOINTS AND FISH
JOINT CHAIRS FOR RAILWAY RAILS
"
In order to give additional bearing surface between fish plates or the jaws of
fish joint chairs and the rails of railways I reduce the thickness of the vertical
web of the rail at the rail ends where the fish plates are to be secured to it--this
allows of the fish plates being made thicker along their top and bottom edges
where they abut against the head and foot of the rails and in this way a greater
extent of bearing surface is obtained between the top and bottom of the fish plates
and the head and foot of the rails respectively.
It is not necessary that the whole depth of the web of the rails should thus
be reduced in thickness the web might have made in it on each side a groove
where it meets the head and foot the central part of the web being left of the
original thickness. In this case the inner sides of the fish plates or jaws where
they are to abut against the web would be made with corresponding grooves and
projections Or the web and fish plates or jaws where they abut against one
another might have a greater number of grooves and projections formed along
them to effect the same object of obtaining greater bearing surface between the
rails and fish plates or jaws.
The fish plates may be rolled with the grooves and projections on them.
The grooves on the opposite sides of the rail web at the rail ends may be
produced by means of circular cutters or saws or they may be moulded upon the
sides of the web by a press or may be produced at the time when the rail is being
Din cir

page_text: rolled. In this case the rails might also be made with depressions at intervals in
the sides of the web of the rail all along its length. In this way the rails may be
made lighter without reducing their strength.
The fish plates may be formed either with or without prolongations extending
below the foot of the rails as desired.
In some cases I make each pair of fish plates in one piece the connection
between them being below the rails and I also make them with a horizontal web
extending outwards from them at the bottom along each side so forming them into
a joint chair which may be made to rest on a sleeper.
In this case I first roll the chair with the portion which is to form its flat base
of a U form and with two fish jaws extending outwards horizontally from the
lower part of the two side limbs of the U and subsequently I straighten out the
bend of this central U shaped piece so as to make it form a flat base and so as to
bring the side pieces extending from it into a position at right angles to the
flat base and to the proper distance apart for the end of a rail to be received
between them.
The inner faces of the side pieces or jaws may as the chair is rolled be made
either with alternate grooves and projections to fit against corresponding grooves
and projections on the sides of the rails or may be shaped like ordinary fish plates
simply to fit against their bottom and top flanges they may also have a central
groove or grooves formed along them to save weight.

FREDERICK CHARLES WINBY of Palace Chambers St. Stephens in the City of
Westminster IMPROVEMENTS IN RAILWAY RAILS AND IN FISH JOINTS AND FISH
JOINT CHAIRS FOR RAILWAY RAILS
"
In order to give additional bearing surface between fish plates or the jaws of fish
joint chairs and the rails of railways I reduce the thickness of the vertical web of
the rail at the rail ends where the fish plates are to be secured to it-this allows
of the fish plates being made thicker along their top and bottom edges where they
abut against the head and foot of the rails and in this way a greater extent of
bearing surface is obtained between the top and bottom of the fish plates and the
head and foot of the rails respectively.
It is not necessary that the whole depth of the web of the rails should thus be
reduced in thickness the web might have made in it on each side a groove where
it meets the head and foot the central part of the web being left of the original
thickness or,
the thickness of this part of the web might likewise be reduced and
the fish plate stamped accordingly. In this case the inner sides of the fish plates
or jaws where they are to abut against the web would be made with corresponding
grooves and projections. Or the web and fish plates or jaws where they abut
against one another might have a greater number of grooves and projections
formed along them to effect the same object of obtaining greater bearing surface
between the rails and fish plates or jaws.
The fish plates may be rolled with the grooves and projections on them.
The grooves on the opposite sides of the rail web at the rail ends may be
produced by means of circular cutters or saws or they may be moulded upon the
sides of the web by a press or may be produced at the time when the rail is being
rolled-In this case the rails might also be made with depressions at intervals in
the sides of the web of the rail all along its length. In this way the rails may be
made lighter without reducing their strength.
The fish plates may be formed either with or without prolongations extending
below the foot of the rails as desired.
In some cases I connect together the two fish plates which are on the opposite
sides of the rails by a connection below the rails and I make this connection to
extend outwards along each side so as to form a joint chair which may be made to
rest on a sleeper or directly upon the ballast if preferred.
Figures 1 shew a cross section and side elevation of the ends of the two rails
coupled together by fish plates formed as above described.
Figures 2 shew similar views of a fish joint in which the fish plates are made to
lap under the foot of the rails.
Figures 3 shew similar views of a fish joint in which the fish plates are not only
made to lap under the foot of the rails but are also prolonged for a distance
downwards.
Figures 4 shew similar views of a fish joint in which the fish plates are at the
bottom held by a wedge piece into a joint chair.
Figures 5, 6, 7 and 8 shew similar views of other fish joints in which the fish
plates are held into chairs of different forms and constructions the nature of which
is clearly shewn by the several figures.
In each of the examples shewn the inner face of that part of the fish plates
which is to abut against the vertical web of the rail is made with a longitudinal

page_text: groove in it along its centre-so producing two longitudinal projections along the
inner face of this part of the fish plate one along the top the other along the
bottom.
On both sides of the rails at their ends longitudinal grooves corresponding to
these longitudinal projections are formed as above described into the vertical
web. The fish plates are as usual secured by bolts and nuts to the sides of the
rails. In each of the figures the rails are shewn to be of the same section
but they might be of other sections. By forming the longitudinal grooves into the
sides of the web at the end of the rails in the manner above described just above
and below the foot and head of the rails respectively-the radius curve between
the head or foot and web can be diminished where the grooves are formed―
this gives still more extended bearing surface than if the same curvature were
maintained..
In Figure 4 the fish plates are at the bottom locked together and prevented from
bending outwards away from one another by a chair A into which they are locked
by a wedge piece B drawn downwards by keys C driven through slots in bolts D.
In Figure 5 they are held together in a somewhat similar chair by keys B.
In both these arrangements the chairs are designed only to lock together the
lower parts of the two fish plates on the two sides of the rails and not to take any
bearing upon the ballast.
In Figure 6 the chair A is shewn to be of a form to rest on and be affixed in
the ordinary manner to a wooden sleeper-the fish plates are also held in the chair
by a wooden key B. In Figures 7 and 8 the chairs A are shewn to be of a form
to rest upon the ballast and so give support to the joint.
In Figures 9 I have shewn how a rail may be rolled with depressions at
intervals in the sides of the web of the rail all along its length so as to reduce
their weight without reducing their strength.
The cross section is taken through one of the thinner portions A of the web say
at the line X Y in the side view-the thicker portions B of the web remain of the
usual thickness. The side view shows a portion of the rail on a scale one half the
size of the sectional view.
Other sections of rail than the one shown can similarly be rolled with varying
thicknesses of web
Having thus described the nature of my Invention and the manner of performing
the same I would have it understood that I claim :-
First. The construction of fish plates with longitudinal, projections along the
top and bottom of their inner face where it abuts against the rail web to enter
corresponding grooves in the web substantially as described.
Second. The construction of railway rails with a groove or grooves at their
ends on either side of the vertical web just below and above the head and foot of
the rail respectively substantially as described.
Third. Connecting together the bottom parts of the two fish plates of a rail fish
joint by a connection below the rails extended outwards on both sides so as to
form a fish plate chair substantially as described and shown at Figures 4, 5,
6, 7 and 8.
Fourth. The manufacture of rails with the vertical web reduced in thickness at
intervals along its length substantially as described.
In witness whereof I the said Frederick Charles Winby have hereunto set
my hand and seal this Seventh day of December in the year of our Lord
One thousand eight hundred and eighty two.
