Improvements in the Construction of Boilers, suitable for Hot Water
Heating Apparatus.
1, GEORGE NEWSUM, of 5 Fairfax Road, Beeston Hill, Leeds, in the County of
York, Printers Engineer 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 :-
The object of this invention is to arrange a boiler suitable for heating by means
of hot water, the interior of buildings, conservatories, and the like, by so constructing
the boiler that a considerable additional amount of heating surface is obtained in a
manner that the major portion of heat emitted from the fuel is utilized in heating
the water, and thus by the additional heat obtained to more effectually force the
hot water through a longer length of pipes than is the case with boilers occupying
the same space and of the ordinary construction.
In describing my invention in detail reference is made to the accompanying
drawings in which
Fig. 1 represents a sectional elevation through line a. b. in Fig. 2 of a boiler
constructed according to my invention.
Fig. 2 is a plan of the same.
Fig. 3 a sectional elevation through line c. d. with the bottom portion and fire bars
removed, and
Fig. 4 is a sectional plan through line e. f. in Fig. 1.
The outside casing A of the boiler is by preference made conical, and has a water
space B extending all round, an opening C is formed at the top for the supply of
fuel to the fire space D. E and F below. The boiler is supported by a casing R
arranged to carry the fire bars G in any suitable manner, and into the fire space D
and ashes pit H below, an opening is formed through the said casing, which is
provided with a door S of the ordinary construction and hinged to the casing at P. P.
thus affording means of access to the fire and ashes pit.
Within the space E formed by the outer casing of boiler, 1 place hollow vessels J.
by preference at an inclination. The said vessels are coupled together at top and
bottom by the respective pipes K and L the latter pipes are also connected by
suitable branches with the interior of outer casing A.
The connecting pipe K at the top of the said vessels is coupled to the pipes M,
which are also coupled by pipes T. T. to the upper portion of the outer casing A.
and through which the hot water flows to the pipes fixed in the building to be heated,
the return flow of water entering the boiler near the bottom through openings N. N.
arranged in a similar manner as with ordinary boilers, thus obtaining a continuous
circulation of water through the boiler and pipes.
By the additional amount of heating surface obtained by a boiler constructed in
the manner described, the water therein is more effectually heated, and in accordance
with the extra heat imparted to the water, the latter may be forced through a
proportionately longer length of pipes than is the case with a boiler occupying the
same space and constructed in the ordinary manner.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A boiler in the interior of which are placed hollow vessels J connected together

page_text: and to the outer casing A by suitable pipes all arranged substantially in the manner
as shown and described.
