page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DAUBNEY, HOLMES, of No. 55, St. John's Square, in the County of Middlesex,
Engineer, send greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Nineteenth day of July, in the third year
of His reign, did, for Himself, His heirs and successors, give and grant
unto me, the said William Daubney Holmes, His especial licence, that I,
the said William Daubney Holmes, my exors, adñors, and assigns, or such
others as I, the said William Daubney Holmes, 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 herein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, and also in all His said Majesty's
Colonies and Plantations abroad, my Invention of "A NEW METHOD OF
HEATING HOUSES AND OTHER BUILDINGS, AND OF APPLYING HEAT TO VARIOUS MANU-
FACTURES AND OTHER PURPOSES;" in which said Letters Patent is contained a
proviso obliging me, the said William Daubney Holmes, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of

page_text: the said recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Daubney Holmes, do hereby declare that the nature of my said
Invention consists in the use of oil and other liquids, the boiling points of
which are at higher temperatures than the boiling point of water when under
the same atmospheric pressure, to convey heat from the fire or source of heat
to the apparatus or surface to be heated, by causing the said oil to circulate
by means of the variation in its specific gravity at different degrees of tempera-
ture, on the same principle that water is now made to circulate in the various
apparatus now used for that purpose; and in further compliance with the said
proviso, I, the said William Daubney Holmes, do hereby describe the manner
in which my said Invention is to be performed by the following description
thereof, reference being had to the Drawing annexed, and to the figures and
letters marked thereon (that is to say):-
DESCRIPTION OF THE DRAWING.
The principle of heating houses and other buildings, as also of applying heat
to various manufactures and other purposes, by the circulation of hot water
being already known, and my Invention being confined only to the substitution
of oil and other liquids of the kind herein before described for water in such
cases, it will only be necessary to describe one mode of carrying my said
Invention into effect, and I have here selected the heating of an oven for my
example. In Figure 1, A, A, B, C, is a cast-iron pipe entering the top of
the outer casing or jacket of the oven at one end, and the bottom of it at the
other end; D is the oven; E is a funnel to supply the oil through; and F is
an air-cock to suffer the air to escape while the pipe and the space between.
the oven and the jacket are filling with oil. Figure 2 is a plan of the oven and
apparatus connected therewith, G being the mouth of the oven. In order to
set this apparatus to work, the pipe A, A, B, C, and space between 'the jacket
and the boiler being filled with oil or other liquid as aforesaid, heat by means of
a furnace or other contrivance must be applied to the serpentine part of 'the
pipe A, A; this will cause the oil or other liquid employed to circulate in the
direction of the arrows, provided always that the oil or other liquid must never
be heated to a degree above 400 degrees of Fabrenheit. Now, whereas I claim
as my Invention the use of oil and other liquids, the boiling points of which
are at higher temperatures than the boiling point of water when under the
same atmospheric pressure, as media instead of water for conveying heat from
the fire or source of heat to the apparatus or surface to be heated, by means

page_text: of its continuous flow or circulation as aforesaid, whereby I am enabled to heat
houses and other buildings, and to apply heat to manufactures and other
purposes of a much higher temperature on the said principle of continuous
circulation than can be effected by the use of water for that purpose; and such
my Invention being to the best of my knowledge and belief entirely new, and
never before used within that part of His said Majesty's United Kingdom of
Great Britain and Ireland called England, His said Dominion of Wales, or
Town of Berwick-upon-Tweed, nor in any of His said Majesty's Colonies or
Plantations abroad, I do hereby declare this to be my Specification of the
same, and that I do verily believe that this my said Specification doth comply
in all respects fully and without reserve or disguise with the proviso in the
said herein-before in part recited Letters Patent contained, wherefore I hereby
claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said William Daubney Holmes, have hereunto
set my hand and seal, this Sixth day of December, One thousand eight
AND BE IT REMEMBERED, that on the Sixth day of December, in the
year of our Lord 1832, the aforesaid William Daubney Holmes came before
our said Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Inrolled the Nineteenth day of December, in the year of our Lord One
thousand eight hundred and thirty-two.
