Engineer WILLIAM ACKROYD, Justice of the Peace of The Wheatleys,
Birkenshaw, Worsted Spinner and THOMAS HENRY ACKROYD, of Oakroyd Hall,
Birkenshaw, Worsted Spinner, all in the County of York do hereby declare the
natnre of this invention to be as follows:-
The object of our invention is to utilize the waste or residual heat and gases of
marine boilers for heating the feedwater of the same.
We employ an economiser consisting of an arrangement of preferably vertical
pipes and scrapers upon the said pipes.
The said economiser is placed in any suitable position within the flues, funnels,
or uptakes of the said marine boilers.
When placed within the funnel, we prefer the pipes to be placed vertically around
the inside periphery, leaving the required space for the waste heat or residual g
1 gases
in the centre of the chimney.
For internally cleaning the pipes at the bottom, we employ screwed metal plugs
at the end of each pipe, so that when the plugs are unscrewed or taken out, each
pipe can be thoroughly cleaned.

We JOHN WILLOUGHBY of the firm of Willoughby and Company of Gomersal,
Engineer, WILLIAM ACKROYD, Justice of the Peace, of The Wheatleys, Birkenshaw,
and THOMAS HENRY ACKROYD, of Oakroyd Hall, Birkenshaw, Worsted Spinner,
do hereby declare the nature of this invention, and in what manner the same
be performed, to be particularly described and ascertained in and by the following
statement :-
to
The object of our invention is to utilize the waste or residual heat and gases of
marine boilers for heating the feed water of the same or for other suitable
purposes.
We employ an economiser consisting of an arrangement of preferably vertical
pipes, or a coil of pipes may be employed.
The said economizer is placed in any suitable position within the flues, funnels,
or uptakes.
When placed within the funnel we prefer the pipes to be placed vertically around
the inside periphery of the said funnel, leaving the required space for the waste heat
or residual gases in the centre of the chimney.
For internally cleaning the pipes, at the bottom we employ screwed metal plugs
or preferably flanges opposite the end of each pipe, so that when the plugs or
flanges are unscrewed or taken off, each pipe can be thoroughly cleaned.

Fig. 1 shows a plan of annular box to which the pipes are attached.
Fig. 2 is an elevation of same with pipes broken.
Fig. 3, shows coil within flue or uptake.
We employ an economiser consisting of an arrangement of preferably vertical
pipes B, or a coil of pipes may be employed see Fig. 3.
The said economiser is placed in any suitable position within the flues, funnels, or
uptakes.
When placed within the funnel A we prefer the pipes B to be placed vertically
around the inside periphery of the said funnel, leaving the required space for the
waste heat or residual gases in the centre of the chimney, the pipes preferably
fitting into the annular box D placed at the top and bottom with suitable
inlet and outlet.
For internally cleaning the pipes at the bottom we employ screwed metal plugs
or preferably flanges G opposite the end of each pipe, so that when the plugs or
flanges are unscrewed or taken off each pipe can be thoroughly cleaned.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The use and employment (within the chimney or uptake of marine boilers) of an
economiser consisting of tubes for utilizing the waste or residual heat and using it
for any suitable purposes such as herein shown and described.
