Complete Specification Leit, 2nd Sept., 1897-Accepted, 2nd Oct., 1897
Improvements in Steam Boilers for Motor Cars, Tramway
Locomotives, Steam Launches, Tugs, and the like.
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
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 chief object of our
Invention is to prevent the emission of visible steam from the chimney or
funnel.
In applying our Invention to a vertical boiler such as a Field tubular boiler
we connect the steam exhaust pipe from the engine to a coil of pipes placed
near the top of the fire box preferably immediately below the chimney the end
of the coil terminating in a nozzle at the bottom of the chimney; or in place of
the nozzle we make a number of holes in the upper coil; by either of these means
the exhaust steam will be superheated and enter the chimney in a highly vapourized
state and escape in an invisible condition.
The coil also serves as a baffle to prevent the flame and hot gases from the
furnace passing directly into the chimney and causes them to act more efficiently
upon the water tubes and other portions of the boiler.
Dated this 3rd day of December 1896.

Improvements in Steam Boilers for Motor Cars, Tramway

We, WILLIAM WILKINSON, of Holme House Foundry, Wigan, in the County
af 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
locomotives, steam launches, tugs, and the like, and the chief object of our
Invention is to prevent the emission of visible steam from the chimney or
funnel.

page_text: In applying our Invention to a vertical. boiler such as a Field tubular boiler
we connect the steam exhaust pipe from the engine to the coil of pipes placed
near the top of the firebox preferably immediately below the chimney.
The accompanying drawing is a sectional elevation of a Field tubular boiler
in which a designates the outer casing b.the inner casing or firebox, c the firebars,
d the ashpan the chimney or funnel, f the water tubes, 9 the steam exhaust
pipe from the engine and h the coil of pipes placed near the top of the firebox b
immediately below the chimney e.
The coil of pipes h may terminate in a nozzle h¹ as shown at the bottom of the
chimney or in place of the nozzle h¹ we make a number of holes in the upper
coil of the pipes h.
By means of the exhaust steam escaping either through the nozzle h¹ or the
perforations it (the exhaust steam) will be superheated and enter the chimney e
in a highly vapourized state and escape in an invisible condition.
The coil h also serves as a baffle to prevent the flame and hot gases from the
furnace passing directly into the chimney e, and causes them to act more efficiently
upon the water tubes f and other portions of the boiler.
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:
1. The combination with the steam exhaust pipe in a boiler of the indicated
type, of the coil of pipes h arranged and operating substantially as and for the
purposes herein set forth.
2. The general arrangement and combination of parts embodying our improve-
ments in boilers of the indicated type substantially as and for the purposes.herein
set forth.
