page_text: BARNES, of Wigan, in the County of Lancaster, Engineer, send greeting.
WHEREAS His 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 October, in the fourth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Richard Barnes, my exors, admors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said Richard Barnes, my
exors, admors, and assigns, or such others as I, the said Richard Barnes,
my exors, admors, and 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 "A CERTAIN
MACHINE OR APPARATUS POR PRODUCING, BY THE COMBUSTION OF GAS OR OIL, HEATED
AIR FOR WARMING THE INTERIOR OF BUILDINGS, AND WHICH MACHINE AND APPA-
RATUS MAY BE APPLIED AT THE SAME TIME TO GIVE LIGHT;" in which said Letters
Patent is contained a proviso obliging me, the said Richard Barnes, 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 Majesty's High
Court of Chancery within two calendar months next and immediately after the
date of the said recited Letters Patent, as in and by the same, referenco 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
Richard Barnes, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following description thereof, (reference being
had to the Drawings hereunto annexed, and to the figures and letters marked
thereon,) that is to say :-
My Invention consists in the combination of mechanical means as described
below, by which I cause a current of air to pass over and in contact with
flame produced by the combustion of gas or oil, or over and in contact with
metal heated by such flame, so as thereby to produce or obtain a sufficient
quantity of heated air, and by the diffusion of such heated air throughout
the interior of the building required to be warmed, to raise the temperature
of the air therein to the required degree of heat or warmth, and at the same
time to give light, if required, by means of the said flame so produced as
aforesaid; and by reference to the Drawings hereunto annexed, and the
following descriptions of such Drawings, the means by which I propose to
effect the above-mentioned purposes may be fully understood.
Description of Figure 1, such Figure being a representation of my patent
heat dispenser. A, bottom on which the machine stands, in which is a hole B,
for the receiving of cold air, surrounded by a ring or hoop C, for the purpose
of protecting from too strong a current of air the annular lights or flame D
produced by the combustion of gas issuing out of the tube E, which is
connected with a service pipe supplying gas. F, a metal disk against which
the cold air which enters at B rushes, and is thrown back on the lights or
flame D, where it is heated, and passing into the cone G, between the vessel
H and the disk F, ascends either through the opening or socket I, in which a
pipe is fixed to convey the heated air into any adjoining apartments, or through
the aperture J, and combines with the cold air, in which the machine is
placed, and forms or produces the desired temperature. K, an outer casing
between which and the vessel H is a space L, through which a current of
cool air passes, merely to prevent accident or inconvenience.
Description of Figure 2, being a representation of my patent heat dispenser,
which is to be used when light as well as heat is required.-A, bottom in which
is an aperture to receive a plate of glas B, surrounded by a hoop or ring C, at
the outside of which are other apertures D, through which the current of cold
air is conveyed up the hoop or ring C, or to the annular flame or lights F,
produced by the combustion of gas issuing out of the tube E, which is
connected with a service pipe supplying gas, and which tube E is supported
by the ledge G, from the inside of the ring or hoop C, and passes over the

page_text: flame or lights F into the cone H, which may be made of any reflecting
metal or material, and discharges itself through the apertures I into the
buildings, roon, or lobby within which the machine orappar atus may be
placed, or by means of pipes or tubes into any adjoining apartment. K, an
inner vessel of any form or shape, the lower half of which is of glass, as at L.
M, an outer casing, the lower half of which is either open or glazed, as
the said inner vessel is at L, and provided with slides, as at N, to cover or
open the lights at pleasure. O, a space between the outer casing M and the
inner vessel K, at the bottom of which are apertures, through which a current
of cold air passes into the space O, and discharges itself at the top P, to
preserve the glass from being broken by the heat, also to keep the outer
casing cool; and to prevent accident or inconvenience I dispense with the
metal disk in the last-mentioned machine and apparatus to be used for giving
light as well as heat, and convey the cold air to or at the outside of the lights
or flame, instead of the inside, as mentioned in the description of Figure 1;
notwithstanding such variation the principle remains the same.
Description of Figure 3, being a variation in the construction of my said.
patent heat dispenser, when the air to be heated and diffused throughout the
building intended to be warmed is required not to be brought into immediate
contact with the flame.-A, A, the bottom on which are placed the hollow
close vessels B, B, B, in which are fixed the tubes C, C, C, out of which issue
the gas lights D, D, D. E, E, E, are open spaces to admit cold air, which after
supporting combustion escapes at the tops of the vessels B, B, B, into the
chimney of the building, or otherwise, as may be convenient, through the
pipe F (regulated by the cock f). G, G, G, are spaces for the admission of
cold air, which passing over the heated exterior surfaces of the vessels
B, B, B, becomes heated, and escapes at the opening H, H, into the building
or room, and thereby increases the heat of the air therein to the required
degree of temperature. I, an inner casing to keep the current of air passing
through the spaces G, G, G, in closer contact with the heated exterior surfaces
of the vessels B, B, B. J an outer casing, between which and the inner
casing I is a space K for cold air to pass through and escape at L, L, for the
purpose of keeping the outer casing cool, and to prevent accident. Should
the use of oil be preferred, a large Argand lamp or Argand lamps will have
to be introduced in the place and stead of the annular ring containing and
supplying gas, such Argand lamp or Argand lamps to be connected by a
conveyance pipe with a fountain of oil in the same machine or apparatus,
or in some convenient part of the building or room wherein the same machine
or apparatus may be placed.

page_text: Now let it be understood, that although I, the said Richard Barnes, have
given Drawings and descriptions of the most convenient and economical
machines, yet I do not intend to restrict myself to the use of machines and
apparatus of the exact form and construction delineated in such Drawings,
but reserve a right to vary and alter the form thereof according to the principle
of my said Invention, as may be the best adapted to the place or places
wherein they shall be fixed, or as circumstances may render necessary.
In witness whereof, I, the said Richard Barnes, have hereunto set my
hand and seal, the Thirteenth day of December, in the year of our
Lord One thousand eight hundred and thirty-three.
