Improvements in Steam Boilers for Motor Cars, Tramway Loco-
motives, Steam Launches, Tugs, and the like.
We, WILLIAM WILKINSON, of Holme House Foundry, Wigan, in the County of
Iancaster, Mechanical Engineer, and SAMUEL TAYLOR, of 60 Market Place, Wigan
aforesaid, Gentleman, do hereby declare the nature of this Invention to be as
follows:-
Our invention relates to improvements in steam boilers for motor cars, tramway
locomotives, steam launches, tugs, and the like, and the object of our Invention is
to heat the feed water for the steam boiler.
In carrying our Invention into effect we employ a closed ashpan and fit in this
pan a horizontal coil of pipes as near as convenient to the under side of the fire
bars; one end of the coil of pipes is connected to the feed pump or injector by
which the water is fed into the coil of pipes and the other end of the coil is
connected to the steam boiler so that the feed water is heated in its passage to
the boiler.
As an addition to the coil before described we may fit a vertical coil of pipes in
the ashpan and cause the water to enter the bottom of this coil and then pass
through it and the horizontal coil to the boiler.
In either arrangement the coil may serve as a suction pipe and be placed between
a supply tank and the pump thereby heating the feed water before it reaches the
pump or injector.

We, WILLIAM WILKINSON, of Holme House Foundry, Wigan, in the County of
Lancaster, Mechanical Engineer, and SAMUEL TAYLOR, of 60 Market Place, Wigan
aforesaid, Gentleman, 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:-
Our invention relates to improvements in steam boilers for motor cars, tramway

which the water is fed into the coil of pipes and the other end of the coil is

In the accompanying Sheet of Drawings
Figure 1 is a sectional elevation of the ashpan, fire bars and the lower part of
the fire box of a steam boiler of the indicated type fitted with our improvements,
and Fig. 2 is a plan of the same with the fire bars removed.
In these views, a designates the outer casing, b the inner casing or firebox,
the fire bars, the ashpan, and e the horizontal coil of pipes connected at one
end to the feed pump or injector and at the other end to the steam boiler.
As an addition to the horizontal coil e we may fit a vertical coil of pipes in the
ashpand and cause the water to enter the bottom of this coil and then pass through
it and the horizontal coil e to the boiler.
In either arrangement the coil may serve as a suction pipe and be placed between
a supply tank and the pump or injector thereby heating the feed water before it
reaches the pump or injector.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
In a boiler of the type indicated the combination with the ashpan and fire bars,
of a coil or coils of pipes placed in the ashpan as a means for heating the feed water
substantially as herein set forth.
