I FREDERICK JOIN BURRELL of St. Nicholas Works Thetford in the County
of Norfolk, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
The object of this Invention is to provide a means whereby Road Locomotives
of the usual construction and height from the ground may, without prejudicing
their efficiency in other respects, be fitted with an arrangement so as to enable
them to pass through shallow rivers or watercourses without putting the fire out,
even though the water shall be considerably above the furnace; and also whereby
the fuel can be added to the furnace and steam pressure maintained in the boiler
whilst passing through the said waters. To enable this to be done I utilize
1stly a water tight ashpan combined with a downtake or air conductor of sufficient
depth to reach above the surface of the water in the river. 2ndly I fit the fire
door with a water tight hopper also carried up the necessary height & fitted with
a door. 3rdly I make the smoke box and door watertight and thus protect all the
interior heating surface of the boiler from direct contact with the water in the
river.

Improvements in Road Locomotives.
I, FREDERICK JOHN BURRELL, of St. Nicholas Works, Thetford, in the County
of Norfolk, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of this invention is to provide a means whereby road locomotives of
the usual construction and height from the ground may without prejudicing
their efficiency in other respects, be fitted with an arrangement so as to enable
them to pass through 'shallow rivers or watercourses without putting the fire
out, even though the water shall be considerably above the furnace; and also
whereby the fuel can be added to the furnace and steam pressure maintained in
the boiler whilst passing through the said waters.
To enable this to be done I utilize firstly, a water-tight ashpan combined with
a downtake or air conductor of sufficient depth to reach above the surface of the
water in the river.

page_text: Secondly, I fit the fire door with a watertight hopper also carried up the
necessary height and fitted with the door.
Thirdly, I make the smoke box and door watertight and thus protect all the
interior heating surface of the boiler from direct contact with the water in the
river.
:
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a side elevation showing my invention applied to a road.locomotive.
Fig. 2, is an end elevation of same.
Fig. 3, is a plan of the road locomotive.
In Fig. 1, a is the boiler of the locomotive having a fire box 6 of the usual con-
struction, c is the water tight ashpan combined with the downtake / for
conducting air to the underside of the fire bars and extended upwards to the
point e where it is fitted with a door for regulating the draught.
The door is placed sufficiently high to reach above the surface of the water in
the river or stream through which the locomotive may be caused to pass.
In place of the ordinary fire door I fit a watertight hopper g also carried up
the necessary height and fitted with a door h through which fuel is fed to the
firebox b.
I also make the smokebox j and its door k watertight and thus protect all the
interior heating surface of the boiler from direct contact with the water in the
river.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. In road locomotives or traction engines the combination of sealed water-
tight ashpan fixed on a downtake and hopper and smokebox door, substantially
as herein described and according to the accompanying drawing.
2. In road locomotives or traction engines, the means of protecting the interior
heating surface of the boiler from direct contact with the water in the river or
stream through which the locomotive is caused to travel.so that fuel can be added
to the furnace and steam pressure maintained in the boiler whilst passing through
the said waters, substantially as described.
3. In road locomotives or traction engines, the combination of the various
parts fully described in the above specification for the purpose specified.
