page_text: I, GEORGE CHESSWAS of 2, South Street, Isleworth, Middlesex, Ironmonger, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in rails for tramways and has for its
object to enable ordinary road vehicles to pass over or across the said rails without
causing undue strain or shock to the wheels and axles of such vehicles.
In tramway rails as hitherto constructed the sides or edges of the upper parts
or flanges of the rail are formed of straight lines parallel with one another, and
as these sides or edges generally protrude a short distance above the level of the
roadway they form obstructions to the wheels of a vehicle passing over or across
them so as to cause the wheels to skid or slide along them for some distance and
then to be suddenly jerked across the line thus causing a severe strain on the
said wheels and their axles.
Now according to my invention I cvercome this objection by forming the said
sides or edges of the upper parts or flanges of the rails with curves or undulations
so constructed that the wheels of any vehicle coming or bearing against them
shall be brought gradually inwards towards the rail and caused to pass over the
same without any skidding or straining thereby preventing shock to the vehicle
and the swerving or swaying motion so often produced when crossing rails as
hitherto constructed.
Doted this 22nd day of October 1896

I, GEORGE CHESSWAS of 2, South Street, Isleworth, Middlesex, Ironmonger, 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 improvements, in rails for tramways and has for its
object to enable ordinary road vehicles to pass over or across the said rails without
causing undue strain or shock to the wheels and axles of such vehicles.
In tramway rails as hitherto constructed the sides or edges of the upper parts
or flanges of the rail are formed of straight lines parallel with one another, and
as these sides or edges generally protrude a short distance above the level of the

page_text: roadway they form obstructions to the wheels of a vehicle passing over or across
them so as to cause the wheels to skid or slide along them for some distance and
then to be suddenly jerked across the line thus causing a severe strain on the
said wheels and their axles.
Now according to my invention I overcome this objection by forming the said
sides or edges of the upper parts or flanges of the. rails with curves or undulations
so constructed that the wheels of any vehicle coming or bearing against them
shall be brought gradually inwards towards the rail and caused to pass over the
same without any skidding or straining thereby preventing shock to the vehicle
and the swerving or swaying motion so often produced when crossing rails as
hitherto constructed.
In order that the invention may be more clearly understood reference is had to
the accompanying drawing which shows my improved rail in plan. As shown the
top of the rail A instead of being made straight is curved or sinuous so that
the outer and inner edges are curved at every point. By this means the wheels
of vehicles will obtain a grip on the rail so that they will not slip. The rail is
provided with the usual straight groove a receiving the flanges of the tram car
wheels.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. An improved rail for tram ways and the like having the upper part of flange
of sinuous or curved form substantially as and for the purposes specified.
2. An improved rail for tram ways and the like constructed substantially as
described and shown in the accompanying drawing and for the purposes specified.
Dated this 22nd day of July 1897.
