Improvements in the Manufacture of Steam and Hot Water Boilers.
We, SAMUEL Fox, Clerk, and the Firm of HARTLEY AND SUGDEN, LIMITED,
of Atlas Boiler Works, Halifax, in the County of York, Boiler Makers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of low pressure
steam and low pressure hot water boilers the object being a novel construction
of such boilers to ensure an increased efficiency combined with compactness
and durability.
According to this invention we construct the boiler with a saddle like water
space having elongated sides. Underneath and partly enclosed by the saddle
like water space is a second water space somewhat similar in shape to the first
one but inverted and with its elongated sides reaching almost to the under and
inner side of the bridge of the first saddle like water space and at or near the
bottom of the second water space is the fire box and grate bars, the former of
which may be corrugated if desired. The spaces between the inner and outer
or upper and lower water spaces constitute the flues open at their lower ends
and carried thence around the water spaces to an outlet flue or chimney.
When used as a low pressure water boiler the bridge of the first saddle shaped
water space is curved or semi-circular, but when used as a low pressure steam
boiler it is preferably slightly flattened and additional space is allowed for
water and steam.

We, SAMUEL Fox, Clerk, and the Firm of HARTLEY AND SUGDEN, LIMITED,
of Atlas Boiler Works, Halifax, in the County of York, Boiler Makers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in the manufacture of low pressure
steam and low pressure hot water boilers the object being a novel construction
of such boilers to ensure an increased efficiency combined with compactness
and durability.

page_text: Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a vertical section on line A B of Fig. 3 of the improved low pressure
water boiler.
Fig. 1 is a vertical section on a plane at right angles to and on line C D of
Fig. 1.
Fig. 2 is a vertical section of the improved low pressure steam boiler.
Fig. 3 is a horizontal section of the improved boiler on line E F of Fig. 1.
According to this invention we construct the boiler with a saddle like water
space having elongated sides 2 2. Underneath and partly enclosed by the
saddle like water space 1 is a second water space 3 somewhat similar in shape
to the first one but inverted and with its elongated sides 4 4 reaching almost to
the under and inner side of the bridge of the first saddle like water space 1 and
at or near the bottom of the second water space 3 is the fire box 5 and grate
bars 6, the former of which may be corrugated if desired. The spaces 7, 7
between the inner and outer or upper and lower water spaces 1, 3 constitute the
flues open at their lower ends 8 and carried thence around the water spaces 1, 3
to an outlet flue or chimney 9 (see Fig. 3).
When used as a low pressure water boiler (see Fig. 1) the bridge of the first
saddle shaped water space 1 is curved or semi-circular but when used as a low
pressure steam boiler (see Fig. 2) it is preferably slightly flattened and addi-
tional space 10 is allowed for water and steam.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) The improved construction of low pressure water boiler as herein described
and substantially as illustrated by Figs. 1 and 3 of the annexed drawings.
(2) The improved construction of low pressure steam boiler as herein described
and substantially as illustrated by Figs. 2 and 3 of the annexed drawings.
Doted this 10th day of March 1899.
