WHEREAS Her present most Excellent Majesty Queen Victoria," by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of April, in the eighth year of Her reign,
'did, for Herself, Her heirs and successors; give and grant unto me, the said
James Startin, ny exors, admors, and assigns, Her especial licence; full power,
sole privilege and authority, that I; the said James Startin, my exors, admors,
and assigns, or such others as I; the said James Startin, my exors, admors; or
assigns, should at any time agree with, and no others, from time to time and at
all times during the term of years therein expressed; should and lawfully might
make, use; exercise, and vend, within England, Wales; and the Town' of
Berwick-upon-Tweed, my Invention of IMPROVEMENTS IN BOILING LIQUIDS,
APPLICABLE TO MANY PURPOSES OF DOMESTIC USES, AND PARTICULARLY TO TEA AND
TABLE URNS;" in which said' Letters Patent is contained a proviso, that I, the
said James Startin, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be inrolled
in Her said Majesty's High Court of Chancery-within six- calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same," reference being thereunto had, will more fully and
at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
James Startin, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say:-
My Invention consists, first, of a method of constructing furnaces to be fixed
in urns and such like vessels.
And, secondly, my Invention consists in constructing urns of china, earthen-
ware, or glass, with internal furnaces suitable for consuming fuel.
And in order that the Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a tea or table urn made of china, earthenware, or glass,
having affixed therein a furnace, with a regulator, so as to regulate the 1
introduction of air to support combustion. This furnace is so formed that
the fire bars consist of tubes a, a, on which the fuel rests, hence the heat
imparted to the tubes will produce a constant current of water or other fluid
contained in the urn, thus facilitating the quick transmitting of heat from the
fuel to the fluid, and at the same time the circulation of the fluid through
the bars will tend to preserve the bars so formed. At the upper part of the
furnace is formed a ventilator, consisting of a sliding tube b, having several
Jong openings through, so that according as such sliding tube is more or less
raised, so will be the quantity of air admitted to the fire below to support
combustion. c, c, are a series of holes through which steam as it is generated
in the urn finds a passage away, and by mixing with the products of charcoal
consumed in the furnace prevents the fumes thereof being offensive. I would
remark that a furnace constructed as herein described is also applicable to
urns made of metal, and such description of urns may readily be made there-
with, and the furnace may be applied when constructing other shaped vessels 3
for domestic purposes where heat is desired to be applied to water or other
fluids. And I would also state, that although I believe the mode of arranging
a furnace in an earthenware, china, or glass urn as shewn, to be the best, the
same may be varied, provided a furnace suitable for consuming fuel be applied
within an urn made of earthenware, china, or glass.
Having thus described the nature of my Invention, and the best means I
am acquainted with for performing the same, I would have it understood that

page_text: I do not confine myself to the details shewn, provided the peculiar character of
either part of my Invention be retained; but what I claim is,-
First, the mode of constructing furnaces for urns and other shaped vessels
for domestic purposes, whereby the fuel is placed on hollow bars through
which the fluid circulates, when such arrangement is combined with means of
regulating the passage of air and vapour above, as herein explained.
And, secondly, I claim the making earthenware, china, or glass urns with
internal furnaces for burning fuel, as above described.
In witness whereof, I, the said James Startin, have hereunto set my
hand and seal, this Seventeenth day of October, in the year of our Lord
One thousand eight hundred and forty fu
