PROVISIONAL SPECIFICATION.
Improvements in and connected with Boilers of Kitchen Ranges.
I, JAMES BAZELEY PETTER, of Nautilus Works, Yeovil, in the County of
Somerset, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in arranging constructing and mounting
boilers for kitchen ranges and my present improvements may be described as the
lengthening or continuing of the boiler (usually placed at the back of a Leamington
or close fire kitchen range) below the level of the fire grating so that any incrusta-
tion or deposit arising from the action of the fire upon the water in that part of
the boiler actually in contact with the fire may fall into a part of the boiler not in
contact with the fire from which it can be removed when desired through a manhole
cover or small opening closed by any suitable covering provided for the purpose in
the lower part of the boiler.
The boiler may have one or more centre flues or tubes or flues formed in the
sides or be otherwise suitably arranged so that the products of combustion from the
fire may descend either through or down the centre part of the boiler or against
the outer surfaces of the boiler before passing into the chimney.
Provision is made for cleaning the vertical flues through or around the boiler
and for removing the soot from said vertical flues by a horizontal shaft underneath
terminating with a soot door in the ashpit.
The boiler may be formed with the front part thereof (or that part which is next
to the fire) lower than the back part so that the front part in contact with the fire
will be kept quite full of water and thus prevent the front part being burnt which
otherwise might happen with this new arrangement of boiler and stove.
The boiler can also be made larger if desired by extending the lower front part
below the fire bars or bottom of the grate.

Improvements in and connected with Boilers of Kitchen Ranges.
I, JAMES BAZELEY PETTER, of Nautilus Works, Yeovil, in the County of
Somerset, Manufacturer, 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 improvements in arranging constructing and mounting
boilers for kitchen ranges and my present improvements may be described as the
lengthening or continuing of the boiler (such as is usually placed at the back of
a "Leamington" or close fire kitchen range) below the level of the fire grating
(so that any incrustation or deposit arising from the action of the fire upon the
water in that part of the boiler actually in contact with the fire may fall into a
part of the boiler not in contact with the fire from which it can be removed when
desired through a "manhole" or small opening closed by any suitable covering
provided for the purpose in the lower part of the boiler in the ashpit) in com-
bination with one or more continuous vertical flues or passages formed in the centre
part of such boiler or in the sides thereof or otherwise suitably arranged
.

constructed in accordance with my invention.
Fig. 2 is a sectional plan upon line 2, 2, Fig. 1.
Fig. 3 is a vertical sectional view (upon line 3, 3, Fig. 2) of said boiler set in
position in a "close" range or stove such as is known as a "Leamington" or close 2
fire kitchen range.

< open" range.
c is the fire grating arranged and mounted as shown with the lower part of the
boiler a below the level of such grating c.
The products of combustion take the course indicated by the arrows (see Figs. 3
and 4) first descending completely through the boiler from top to bottom through
the flue and thence by the horizontal shaft e under the bottom of the boiler and
ascending behind the boiler up the shaft or passage of thence escaping to the
chimney. It will thus be seen that a greatly increased heating surface is thereby
obtained while the fire itself only comes in contact with the boiler at a point a¹
much above the lower part of said boiler which has a "manhole" or other suitable
opening such as a² therein to obtain access to the inside of such boiler for
cleaning &c.
The front part a¹ of the boiler a is always kept quite full of water (the back
part a being higher than a¹) thus preventing the part a¹ which comes in direct
contact with the fire itself from being burnt.
;
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 combination with a boiler for kitchen ranges or the like purposes of a
continuous flue or passage (or passages) descending completely through the said
boiler from top to bottom thereof and the lower part of said boiler extending
considerably below the bottom of the fire on the fire grating substantially as and
for the purposes hereinbefore set forth.
2. The combination with a boiler for kitchen ranges or the like purposes of a
continuous flue or passage (or passages) descending completely through said boiler
from top to bottom thereof and the lower part of said boiler extending considerably
below the bottom of the fire on the fire grating with a
"
"manhole or other

boiler substantially as and for the purposes herein before set forth.
3. The combination with a boiler for kitchen ranges or the like purposes the
lower part of such boiler extending considerably below the bottom of the fire on
the fire grating of a "manhole door or opening closed by any suitable covering
in such lower part of such boiler substantially as and for the purposes hereinbefore
set forth.
"
4. I claim the improved general arrangement construction and combination of
parts in and connected with the boilers of kitchen ranges substantially in the
manner and for the purposes hereinbefore described and as illustrated in the
drawings hereunto annexed.
