stood, of Glasgow, in the County of Lanark, North Britain, Stove
and Range Manufacturers, for the Invention of "IMPROVEMENTS IN

"
Scaled the 4th September 1874, and dated the 11th March 1874.
PROVISIONAL SPECIFICATION left by the said James Smith at the
Office of the Commissioners of Patents, with his Petition, on the
11th March 1874.
I, JAMES SMITH, of the Firm of Smith and Wellstood, of Glasgow,
in the County of Lanark, North Britain, Stove and Range Manu-
facturers, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN WATER HEATING APPARATUS FOR STOVES AND RANGES," to be as
follows, that is to say :-
This Invention has for its object to utilise heat which in existing stoves
and ranges is wastefully radiated into the ash-pits, and it consists in fitting
beneath the grate of any stove or range in which it is wished to have
means for heating water an iron or other metal box with pipe connections

water box exposed to the heat radiated through the bottom grate bars is by
preference sloped downwards and forwards, so that ashes may move or
be easily moved downwards into a receptacle, and so as not to impede
the radiation of the heat into the water box.

for the ingress and egress of water to and from it. The surface of this
water box exposed to the heat radiated through the bottom grate bars is by
preference sloped downwards and forwards, so that ashes may move or
be easily moved downwards into a receptacle, and so as not to impede
the radiation of the heat into the water box.
When the stove or range is fitted with a boiler or water heating box
in any of the ordinary positions the ash-pit water heater may be con-
nected thereto by pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Smith in the Great Seal Patent Office on
the 10th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
SMITH, of the Firm of Smith and Wellstood, of Glasgow, in the County
of Lanark, North Britain, Stove and Range Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of March, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Smith, Her special licence
that I, the said James Smith, my executors, administrators, and
assigns, or such others as I, the said James Smith, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
WATER HEATING APPARATUS FOR STOVES AND RANGES," upon the condition
(amongst others) that I, the said James Smith, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six

page_text: calendar months next and immediately after the date of the said Letters
Patent..
NOW KNOW YE, that I, the said James Smith, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accompanying
Drawings, that is to say :—
My said Invention has for its object to utilise heat which in existing
stoves and ranges is wastefully radiated into the ash-pits, and it consists
in fitting beneath the grate of any stove or range in which it is wished
to have means for heating water an iron or other metal box with pipe
connections for the ingress and egress of water to and from it. The
surface of this water box exposed to the heat radiated through the
bottom grate bars is by preference sloped downwards and forwards, so
that ashes may move or be easily moved downwards so as not to impede
the radiation of the heat into the water box.
And in order that my said Invention and the manner of performing
the same may be properly understood I hereunto append a Sheet of
explanatory Drawings, to be herein-after referred to, and representing
a cooking stove as fitted with my improved water heating apparatus. In
these Drawings the same reference numerals are used to mark the same
or like parts wherever they are repeated.
Figure 1 is a horizontal section of the cooking stove, and Figures 2
and 3 are vertical sections as at right angles to each other. In this
example there is on one side of the usual fire-box 1 an oven 2, heated by
means of flue spaces 3, 4, 5, 6, leading from the top of the fire, and on
the other side there is a cistern 7 for water. For heating the water a
cast-iron box 8 is placed directly beneath the grate bars 9, and this box 8
communicates with the cistern 7 by means of two pipe connections 10, 11,
with which arrangement an active circulation of the water takes place,
so that the whole of the water in the cistern 7 becomes pretty equally
heated. The top 12 of the water box 8 is sloped down towards the
front for the casy descent of ashes into the ash pan 13, the open forward
part of which last is ordinarily screened from view by an inclined
5 movable plate 14.
If preferred the water heating box 8 may be connected to a cistern
situated outside of the onsing of the stove or range.

page_text: Having thus particuiarly described my said Invention and the manner
of performing the same, I have to state that I do not restrict myself to
the precise details herein described or delineated, but that what I believe
to be novel and original and claim as the Invention secured to me by
the hercin-before in part recited Letters Patent is, the fitting of stoves
and ranges with water heating apparatus in the form of a box placed
directly beneath the fire so as to be acted on by the downwardly radiated
heat, substantially as herein-before described.
.
In witness whereof, I, the said James Smith, have hereunto set.
my hand and seal, this Eighth day of September, in the year of`:
our Lord One thousand eight hundred and seventy-four.
