COMPLETE SPECIFICATION.
"A New or Improved Construction of Boiler for Hot Water Heating
Apparatus."
I, FREDERICK BATHER SCOTT, of 101. Camberwell Grove, London, S.E., Lighter-
man, 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: —
This invention relates to a new or improved construction of boiler for hot water
heating apparatus and has for object to produce a simple form of boiler adapted
to be heated by any description of stove (oil, gas, coke, coal, or the like) and in
which an efficient circulation of the water shall be cbtained throughout the system
of pipes employed to conduct the water around or through the house building
or room to be heated.
In accordance with this invention I construct the boiler in two portions one
contained within the other. Into the outer portion the water to be heated is
conducted from whence it flows into the inner portion; thence it flows through
an outlet provided at the top through the heating pipes and finally, after cir-
culating throughout the whole system of pipes employed within the building
house or room for heating purposes, re-enters the outer portion of the boiler
where the operation is repeated and so on.
The following is a specification of my invention which will be readily under-
stood upon reference to the accompanying sheet of drawings and the letters and
figures of reference marked thereon, that is to say:
Fig: 1 is a sectional elevation of the outer shell or portion of the boiler.
Fig 2. is a similar view of the inner portion arranged and contained within the
outer portion or shell shewn in Fig: 1, and Fig: 3 shews in sectional elevation
the two portions fixed in position.
Similar letters of reference indicate like parts wherever occurring throughout
the figures.
a is the outer shell or portion of the boiler fitted or resting upon a stove 6 of
any convenient description.
The water to be heated is introduced into this outer portion a of the boiler
through inlet c.
A smoke box d is arranged within the shell a. Communicating with the
smoke box d are pipes or tubes e leading from the stove band by means of which
the smoke and products of combustion are conducted from stove 6 to the outlet f
formed in the smoke box d all as shewn by arrows in Figs: 1 and 2.
g is the inner portion of the liler having vertical tubes h connected around
same. i is a central vertical tube connecting inner boiler g with outlet k at the
top of the outer shell a. 7 is an air valve on outlet shell a fitted with a screwed
plug which plug is removed during the operation of filling the boiler.
The outer and inner shells and the smoke box d may be circular, square, or of
any other convenient shape in plan view to suit requirements.
The water admitted into the outer shell a through inlet c will when it rises to

page_text: the level of the top of the vertical tubes h flow through such tubes into the inner
portion of boiler g and thence upwards through pipe to the outlet & whence it
circulates throughout the system of pipes in connection therewith (not shewn in
the drawings) and is returned to the boiler through inlet c as shewn by arrows
Figs 1, 2, and 3, and so an constant circulation is kept up or maintained.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The new or improved construction of boiler for hot water heating apparatus,
substantially as set forth.
2. In boilers for hot water heating apparatus the two portions arranged one
within the other the outer one provided with water inlets and outlets, and smoke
box and uptakes; and the inner one provided with inlet tubes and outlet tube
all in combination with circulating pipes and heating stove constructed and
operating substantially as hereinbefore set forth.
3. In boilers for hot water heating apparatus the outer shell a provided with water
inlet c, smoke box uptake tubes e, smoke outlet f', water outlet ¹, and air
valve the inner boiler g, provided with the vertical tubes h, h, and i in combina-
tion, and all constructed arranged, and operating, substantially as set forth.
