PROVISIONAL SPECIFICATION left by the said Ambrose Hudd Smith
at the Office of the Commissioners of Patents, with his Petition,
on the 27th October 1868.
I, AMBROSE HUDD SMITH, of No. 7, Mall Place, Clifton, in the
County of Gloucester, Plumber and Gas Fitter, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR WARMING AND HEATING CHURCHES, CHAPELS, AND OTHER
BUILDINGS," to be as follows:-
My Invention consists of a brick chamber beneath the floor, with
a grating over to allow the hot air to pass through. Beneath this
chamber I introduce an air flue in connection with the flooring,
covered with an iron grating. By these means I introduce a current of

page_text: air, which current of air is brought to act upon a ring gas burner,
which gas burner is supplied from an ordinary main by means of a
spanner; by this spanner I am enabled to regulate the amount of heat
required. Underneath this ring burner is a small cistern made of fire-
clay filled with water. The heat from the gas burner acts upon the
water, and causes a steam or vapour to arise, which steam or vapour
passes through pummicestone, which is contained in a cylinder above
the cistern, for the purpose of forming a vapour to moisten the atmo-
sphere contained in the reservoir. Around this is a circular cylinder
made of fire-clay to contain the heat. I cover the whole of this with a
dome made of fire-clay, and also for purifying the same. This dome
is worked by a lever for the purpose of lighting the ring burner. By
these arrangements I get a pure heat, free from smell or smoke, with
a very small consumption of gas.
This heating apparatus can be fixed above the flooring in an
ornamental casc.

page_text: give and grant unto me, the said Ambrose Hudd Smith, Her special
licence that I, the said Ambrose Hudd Smith, my executors, adminis-
trator's, and assigns, or such others as I, the said Ambrose Hudd 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,
excrcise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"HEATING AND WARMING PUBLIC BUILDINGS AND PRIVATE DWELLINGS, HOT-
HOUSES, GREENHOUSES, &c.,". upon the condition (amongst others) that
I, the said Ambrose Hudd Smith, my executors or administrators, by
an instrument in writing under my, or their, or one of their, hands
and scals, 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 Ambrose Hudd Smith, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:―
I construct a square chamber made of bricks, fire-clay, or any other
suitable material. By means of an air shaft introduce a current of
air to act upon a series of ring burners. Underneath these burners or
above (according to circumstances) I employ a water cistern made of firc-
clay; this cistern reaches above and below the burners; the top of this
water cistern is filled with pummicestone I enclose the whole of
this with a bottle-shaped cylinder made of fire-clay. Over the top of
this cylinder I place a dome, likewise made of firc-clay moveable or
fixed. The whole of this apparatus is covered with an iron grating,
fitted flush with the floor. The burner is supplied from an ordinary
main, and lighted according to circumstances.
This Invention can be applied to an ornamental case and fixed in
any position above the floor as may be required.

page_text: C, the ring burner; D, the reservoir for the pummicestone; E, water
cistern; F is a dimut chamber inclosing the whole apparatus connected
with H; G is a
for turning on and off the gas; H, is the
air flue for supplying a current of air to ring burner; I is the dome;
Lis the lever for supporting the dome.
I claim the whole of my Invention as perfectly new.
In witness whereof, I, the said Ambrose Hudd Smith, have here-
unto set my hand and scal, this Twenty-fourth day of April,
in the year of our Lord One thousand eight hundred and sixty-
nine.
