page_text: LETTERS PATENT to James Stone, of Drayton, in the County of
Somerset, Gentleman, for the Invention of "A NEW OR IMPROVED
APPARATUS FOR WARMING BED AND OTHER ROOMS, ALSO APPLICABLE FOR
WARMING OR HEATING CHURCHES, CONSERVATORIES, GREENHOUSES, OR OTHER
33
PROVISIONAL SPECIFICATION left by the said James Stone at the
Office of the Commissioners of Patents, with his Petition, on the
27th August 1872.
I, JAMES STONE, of Drayton, in the County of Somerset, Gentleman,
5 do hereby declare the nature of the said Invention for "A NEW OR IM-
PROVED APPARATUS FOR WARMING BED AND OTHER ROOMS, ALSO APPLICABLE FOR
WARMING OR HEATING CHURCHES, CONSERVATORIES, GREENHOUSES, OR OTHER
BUILDINGS OR ROOMS REQUIRING WARMING OR HEATING," to be as follows:―
This Invention relates to a new or improved apparatus for warming
O bed and other rooms, also applicable for warming or heating churches;
conservatories, greenhouses, or other buildings or rooms requiring

page_text: warming or heating, which consists mainly of two suitably shaped metal
vessels, placed one within the other, having the space between them
filled with a layer of the non-conducting or imperfectly conducting
material, or combination of materials (the glass however or component
part thereof by preference being used as a silicate) described in the
Specification of the Invention for which Letters Patent were granted to
Bristow Hunt on the 6th day of October, A.D. 1871, No. 2652, the same
having been a communication to the said Bristow Hunt from myself
whilst I was resident in Ceylon.
The improved apparatus when in position fills the whole space above
the grate of the fire-place, and when it is to be heated is drawn to the
front thereof, so that the smoke may pass at its back up the chimney
or flue; and when the water (which is contained in the inner vessel) is
made to boil or is sufficiently heated, the apparatus is allowed to remain
in position or is moved to the back of the grate, and the damper or trap
door in the flue closed; and when in. use it will be found to keep a
moderately sized room sufficiently or comfortably warm for at least
twelve hours.
Or, as a modification and instead of using water as the hoating
medium, I construct the apparatus so as to allow of one or more tubes
running throughout its centre, and provide it with a fire-box at one end
and a chimney at the other, and also fill it with the material or materials
above referred to and described in the above-mentioned Specification
mixed with pieces of iron or iron turnings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said James Stone in the Great Seal Patent Office on
the 27th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
STONE, of Drayton, in the County of Somerset, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of August, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
3

page_text: give and grant unto me, the said James Stone, Her special licence that
I, the said James Stone, my executors, administrators, and assigns, or
such others as I, the said James Stone, 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 "A NEW OB IMPROVED APPARATUS FOR WARMING
BED AND OTHER ROOMS, ALSO APPLICABLE FOR WARMING OB HEATING CHURCHES,
CONSERVATORIES, GREENHOUSES, OTHER BUILDINGS OR ROOMS REQUIRING WARMING
OR HEATING," upon the condition (amongst others) that I, the said James
Stone, my executors or administrators, 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 calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Stone, 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, and on reference being had to the
accompanying Drawings, that is to say:-
This Invention relates to new or improved apparatus for warming or
heating bed and other rooms, and churches, conservatories, greenhouses,
or other buildings or places, one modification of the construction and
application of which is illustrated on the accompanying Drawings in
Figure 1, which represents a sectional side elevation of the apparatus
applied to an ordinary fire-place.
The apparatus consists mainly of two suitably shaped metal vessels a, b,
placed one within the other, having a space 6¹ between them (which may
be used as an air chamber for heating air and supplying it to the rooms
or other places) filled with two layers c, d, the outer one c of any
suitable non-conductor of heat, and the inner one d (by preference) of
the non-conducting or imperfectly conducting material or combination.
of materials (the glass however, a component part thereof, by preference
being employed as a silicate) described in the Specification of the In-
vention for which Letters Patent were granted to Bristow Hunt on the

page_text: 6th day of October, A.D. 1871, No. 2652, the same having been a com-
munication to the said Bristow Hunt from myself whilst resident in
Ceylon.
In this modification the improved apparatus is placed, as shown,
above and at the back of the grate, but when desired to be used it is
drawn to the front thereof, so that the smoke from the grate may pass
at its back up the chimney or flue. When the water or the composition
herein-after referred to (which is contained in the vessel 6) is made to
boil (or is sufficiently heated), the apparatus is either allowed to remain
in position or is moved to the back of the grate, and the damper or trap
door in the flue closed, and the heat it retains will keep a moderately
sized room sufficiently or comfortably warm for at least twelve hours,
thereby effecting a great economy in the consumption of fuel.
When using water as the heating medium I prefer to saturate it with
starch or any salt which would not act injuriously on the metal, such as
common washing soda or chloride of calcium, so as to obtain a greater
heat by raising the boiling point of the water.
In a second modification, most applicable when intended for use in
any of the latter of the above-mentioned purposes, I construct the
apparatus as illustrated in Figures 2 to. 6. Figures 2 and 3 represent an
end elevation and longitudinal vertical central section respectively of
this modification in a horizontal form, and Figures 4 and 5 a partly
sectional elevation and sectional plan respectively in a vertical form.
Figure 6 shows a further application of the Invention to a stove heated
by gas.
In this modification I construct the apparatus so as to allow of
one or more tubes x running throughout its centre or other part (which
may also be applied in the first modification, see Figure 1), and provide
it with a fire-box or heating chamber at one end and a chimney e at
the other, and instead of using liquid as the heating medium, as men-
tioned in the first modification, I fill the vessel b with the materials or
combination thereof above referred to, by preference in a powdered state,
mixing with them pieces of iron or iron turnings; or I fill it with well-
washed sand or gravel, which, when heated by the passage of the heated
gases through the flue or flues, will retain considerable heat for a
lengthened period.
The apparatus may be made of various forms or shapes to suit the
special purposes to which it is to be annlied the cenot nuinainte
2

page_text: construction being retained. Amongst its varied uses, in addition to
those above related, may be mentioned its application for warming or
heating bakers' and other ovens, and its use as a portable stove to be
heated in one room and carried to another, and as a means of hatching
eggs.
Having now described the nature and object of my said Invention for
"A New or Improved Apparatus for Warming Bed and other Rooms, also
applicable for Warming or Heating Churches, Conservatories, Green-
houses, or other Buildings or Rooms requiring Warming or Heating,"
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I would remark in conclusion that
I claim as my Invention, the improved apparatus for warming rooms
and other places (and the means of retaining or arresting the escape of
heat), constructed substantially as above described and as illustrated on
the accompanying Drawings, or any mere modification thereof, and its
application to any of the above-mentioned and other similar purposes.
In witness whereof, I, the said James Stone, have hereunto set my
hand and seal, this Twenty-fourth day of February, in the year of
our Lord One thousand eight hundred and seventy-three.
Witness,
BRISTOW HUNT,
Solicitor and Patent Agent,
