PROVISIONAL SPECIFICATION.
An Improved Tubular Boiler for Fireplaces or Stoves.
WALTER JOHN MILLINGTON, 15, Lancefield Street, Harrow Road, W., in the
County of Middlesex, Engineer, do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to manufacture an improved tubular boiler for
fireplaces and stoves.
My invention consists of one chamber of irregular form intersected by one or
more, elliptical or circular tubes fixed vertically, separately or combined.
These tubes may be parallel or taper, or a parallel tube of larger diameter at
bottom than at top, and placed a suitable distance apart to allow space for water to
circulate around the tube or tubes within the shell of boiler as it becomes heated.
The flames and heated gases from the fire will pass upwards through the tube or tubes.
Junctions are also formed to the shell of boiler for the inflow of cold water and the
outflow of heated water, the circulation of the water ensuing in a manner well
known.
The tubes may be welded, rivetted, expanded or cast into the shell of boiler.
A damper may be provided whereby the temperature can be regulated.
In order to fix the boiler, the ordinary back of the stove or fireplace is removed
and the boiler is put in its place, the projecting section containing the tube or tubes
being placed towards the front.
The junctions are then connected with the flow and return pipes, and the boiler is
kept filled with water.
Although my improved tubular boiler as herein before described as applicable to
the back of ordinary fireplaces and stoves, I wish it to be understood that I do
not confine myself to that position, as in some cases it may be more convenient to
fix the same at the side or in other positions according to the constructions of the
fireplace or other stove.
In some cases also the boiler may be fitted with a back flue and damper

COMPLETE SPECIFICATION.
An Improved Tubular Boiler for Fireplaces or Stoves.
I, WALTER JOHN MILLINGTON, of 40, Ashmore Road, Harrow Road, W.,
Engineer (late of 15, Lancefield Street, W.), 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 my invention is to manufacture an improved tubular boiler for fire-
places & stoves or may be independent.
My invention consists of one chamber of irregular form intersected by one or
more elliptical or circular tubes fixed vertically or nearly vertically separately or
combined.
These tubes may be parallel or taper or a parallel tube of larger diameter at
the bottom than the top and placed a suitable distance apart to allow space for
water to circulate around the tubes within the shell of boiler as it becomes heated.
The flames and heated gases from the fire will pass upwards through the tube or
tubes, junctions are also formed to the shell of boiler for the inflow of cold water
and the outflow of heated water, the circulation of the water ensuing in a manner
well known.
The tubes may be welded, riveted, expanded or cast, into the shell of boiler. A

damper may be provided whereby the temperature may be regulated. (This is not
necessarily a part of the boiler.) In order to fix the boiler the ordinary back of
the stove or fireplace is removed and the boiler is put in its place the projecting
section containing the tube or tubes being placed towards the front. The junctions
are then connected with the flow and return pipes and the boiler is kept filled with
water.
Although my improved tubular boiler as hereinbefore described as applicable to
the back of ordinary fireplaces and stoves I wish it to be understood that I do not
confine myself to that position as in some cases it may be more convenient to fix the
same at the side or in other positions according to the construction of the fireplaces
or other stove.
In some cases also the boiler may be fixed with a back flue and damper.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar figures and
letters of reference indicate corresponding particulars.
Fig. 1, is a perspective view of my invention.
Fig. 2, is a front elevation.
Fig. 3 & 4 are cross sections showing tubes.
Fig. 5 is an end view.
Fig. 6, 7, 8 & 9 are top views.
Fig. 10, 11, 12, & 13 are cross sections on the line A B of Fig. 3 & 4 shewing
different forms and arrangements of tubes.
Fig. 14, 15, 16 & 17 are sections through boiler showing the various forms of
tubes on line E F of Fig. 3 & 4.
Fig. 18, 19, 20, & 21 are cross sections on line C D of Fig. 3 & 4.
Fig. 22, 23, 24 & 25, are plans of bottom of boiler on the line G H of
Fig. 3 & 4.
Referring to Figures 3, 4 & 10 to 21, inclusive I are the tubes.
J are the short tubes fixed in combination.
These tubes can be welded, riveted, expanded, or cast into the shell of
boiler.
KK are junction pipes for receiving inflow of cold water from one or both sides
as required.
L, L, are outflows for the passage of the hot water from whence it flows
to a coil, radiator or any other receptacle it may be required for or applied to.
When fitted at the back of an ordinary grate the heated gases pass upwards
through the several tubes, also under the bottom into a flue at back formed in the
brickwork.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture and use of boilers, consisting of an irregular chamber with
tubes I, I, and J, J, passing through the same fitted with inlet and outlet pipes,
-substantially as hereinbefore described and illustrated by the drawings.
2. In combination with boilers constructed arranged and operating as aforesaid a
flue may be formed in the brickwork with an ordinary damper for the regulation of
the heat imparted to the circulating water.
3. The general construction, arrangement, and combination of the several and
respective parts together constituting my invention of improvements in the con-
struction of boilers for fireplaces and stoves substantially, as herein before described
and illustrated by the drawings.
Dated this 21st day of March 1891.
