PROVISIONAL SPECIFICATION.
Improvements in Joints for Rails for Railways, Tramways, and for
like purposes.
We, GEORGE FLETT, of 101 Leadenhall Street London, E.C. and DIOK, KERR
& COMPANY LIMITED of 101 Leadenhall Street, London, E.C., Engineers, do
hereby declare the nature of this invention to be as follows :-
Our invention has reference to an improved form of joint or fish plate connection
for use upon rails for railways, tramways and the like, the object of the invention
being to produce a rail having a practically continuous bearing surface for the
tread of the wheel and thus to obviate the wear, and tear due to the open space
which exists with rails joined in the usual ordinary manner.
In carrying our invention into effect we construct our rail with its head web and
flange formed in any well known manner, and we provide upon one side a fish
plate which makes a bed near to. or upon the web and lies between the underside of
the head and the upper surface of the flange. The other companion fish plate we
form in a special manner by causing it to enter a recess or opening formed like a
jaw within the heads of the meeting rails and thus to complete the continuity of
the rail head or rolling surface by-fitting therein between the ends of the rails
which are to be jointed.
We cause-this special fish plate to be rolled or shaped so as to take the place of
the metal which is cut away from the upper part of the rail head and we make its
lower portion to rest upon the upper surface of the flange, while the fish bolts pass
through the central part of the plate and through the web of the rail in the well
known ordinary manner at present employed with common rail sections.
We prefer to make the holes in one of our fish plates square rectangular, or
other shape which will admit of the bolts not turning when the nuts are being.
screwed or unscrewed, and we may make the opposite fish plate with oval or
enlarged holes to enable expansion to be provided for.
We do not limit the application of our invention to any particular shape or
section of rail but we modify the form and shape of our fish plate or jointing plates
to suit the particular form of rail to which it is to be attached.
We may make each fish plate to enter recesses formed in each side of the rail
head when so.desired, instead of making one continuous or head engaging fish plate
and one web fish plate as hereinbefore described.

We, GEORGE FLETT, of 101 Leadenhall Street, London, E.C. and DICK KERR
AND COMPANY LIMITED, of 101 Leadenhall Street, London, E.C., Engineers, do
hereby declare the nature of this invention and in what manner the same is to
bo performed, to be particularly described and ascertained in and by the following
statement :-
Our invention has reference to an improved form of joint or fish plate connection
for use upon rails for railways, tramways and the like, the object of the invention
being to produce a rail having a practically continuous bearing surface for the
tread of the wheel and thus to obviate the wear and tear due to the open space
which exists with rails joined in the usual ordinary mauner.
In the accompanying sheet of explanatory drawings—
Figure 1 is a sectional end elevation of our joint for a tramway rail.
Figure 2 is an elevation showing one half of the inside fish plate on one side, and
one half of the outside fish plate on the opposite side, and
Figure 3 is a plan.
In carrying our invention into effect we construct our rail with its head A,
web A¹ and flange A2 formed in any well known manner, and we provide upon one
Ride a fish plate B which makes a bed near to or upon the web and lies between
the underside of the head and the upper surface of the flange. The other com-
panion fish plate C we form in a special manner by causing it to enter a recess or
opening D formed like a jaw within the heads of the meeting rails A A and thus
to complete the continuity of the rail head or rolling surface by fitting therein
between the, ends of the rails which are to be jointed.
We cause this special fish plate C to be.rolled or shaped so as to fill the gap D
or take the place of the metal which is cut away from the upper part of the rail
bead and we make its lower portion to rest upon the upper surface of the flange,
while the fish bolts E pass through the central part of the plate and through the
web of the rail in the well known ordinary manner at present employed with
⚫ common rail sections.
We prefer to make the holes F in one of our fish plates square rectangular or
other shape which will admit of the bolts E not turning when the nuts are being
screwed or unscrewed, and we may make the opposite fish plate with oval or.
enlarged boles F to enable expansion to be provided for.
We do not limit the application of our invention to any particular shape or
section of rail but we modify the form and shape of our fish plate or jointing
plates to suit the particular form of rail to which it is to be attached.
We may make each fish plate to enter recesses or gaps formed in each side of
the rail. head when so desired, instead of making one continuous or head engaging
fish plate C and one web or ordinary fish plate B as herein before described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is;-
1. The construction of a fish plate or joint plate for rails, having the upper
surface formed for entering into a recess or gap cut in the meeting rail heads,
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
2. In a tramway or other rail joint the use of a fish plate which enters into a
slot or opening formed within the head of the ends of the meeting rails

the accompanying drawings.
3. In a tramway or other rail joint the use of a fish plate which enters into a
gap formed upon the heads of the ends of the meeting rails on one side, and having
an ordinary fish plate arranged upon the opposite side of the rail webs, substantially
as hereinbefore described and as illustrated in the accompanying drawings.
