CERTAIN IMPROVEMENTS IN OR ON THE MEANS OF LIGHTING THE INTERIOR OF OFFICES, THEATRES, BUILDINGS, HOUSES, OR ANY PLACE WHERE LIGHT MAY BE REQUIRED
Year: 1816

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAC
HADLEY REDDELL, of Orange Court, Leicester Square, in the County of
Middlesex, Engineer, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain and Ireland, bearing
date at Westminster, the Twenty-seventh day of May, in the fifty-sixth year of
His reign, did give and grant unto me, the said Isaac Hadley Reddell, my
exors, admors, and assigns, His special licence, full power, sole privilege
and authority, that I, the said Isaac Hadley Reddell, my exors, adñiors,
and assigns, during the term of years therein expressed, should and law-
fully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN
OR ON THE MEANS OF LIGHTING THE INTERIOR OF OFFICES, THEATRES, BUILDINGS,
HOUSES, OR ANY PLACE WHERE LIGHT MAY BE REQUIRED;" in which Letters
Patent there is contained a proviso obliging me, the said Isaac Hadley
Reddell, under my hand and seal, to 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 His Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said recited Letters Patent,
as in and by the same (relation being thereunto had) may more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Isaac Hadley Reddell, do hereby declare that the nature of my said Inveni-
tion, and manner of performing the same, are particularly described and

page_text: ascertained by the following description in writing, and annexed Drawings
(that is to say)-
My Invention is, in principle, an improved method of fashioning, forming,
and combining certain parts of chandeliers or suitable apparatus to be used in
the lighting of the interior of offices, theatres, buildings, houses, or any place,
with inflammable air or gas, and of the pipes and tubes used and employed to
convey such inflammable air or gas into the same, with a view of preventing,
in an eligible manner, the possibility of danger from the explosion of any such
inflammable air or gas as may escape from any burner, pipe, or tube, and also
any ill effect which might otherwise arise from the smell of such inflammable
air or gas, or the foul air generated or produced during the combustion
thereof. The plan I have invented for these purposes is, the introduction of
such inflammable air or gas by means of a pipe or tube running in the interior
of a larger pipe or tube, which larger pipe or tube shall at one end have free
communication with the open atmospherical air. The pipes or tubes for the
passage of the gas are thus to continue in the interior of the larger pipe or
tube throughout every part of the office, theatre, building, house, or other
place to be lighted, until terminating in the burner or burners to be attached
to the various ends of such pipes or tubes, so that every burner will be ignited
in a suitable glass or lanthorn attached to such larger pipe or tube so com-
municating with the open atmospherical air. By this method all inflammable
air or gas escaping from any burner or interior pipe or tube through which it
is conveyed, and also all smell and heated and foul air generated during the
combustion of such inflammable air or gas, will be immediately carried off
through the exterior pipe or tube into the open atmospherical air, so as to pro-
duce the effects above mentioned. The pipes or tubes, both interior and exterior,
may be constructed of any metal or other material of which pipes or tubes
now in use for the conveyance of gas are constructed; and the termination of
any exterior pipe or tube in which any burner or burners is or are placed
may be of glass, to afford a transparent medium for the diffusion of light.
EXPLANATION OF PLAN No. 1.
A, A, a pipe or tube to pass either into a chimney or the exterior of the
building, to be made widest at the bottom to receive the three smaller tubes
marked B, B, B, which must ascend into it a few inches, and be firmly secured
thereto, and in a similar manner a single light, or any number of lights, may
be applied. C, C, C, three glasses open at bottom, and with short neck and
suitable orifice at top; D, D, D, D, metallic supports to the said glasses and
ornaments below them; E, E, a gas pipe or tube to descend in the inside of

page_text: the other (as represented by the dotted lines, and after diverging into three
parts at I to pass down the three smaller tubes to supply the burners.
EXPLANATION OF PLAN No. 2.
F, F, pipe or tube to convey air from the exterior of the building to supply
the burner in the glass G, the lower part of which should be fixed (by means
of a short neck (to the top of it), and with a suitable orifice thro' it, a small
gas pipe or tube to pass up, in the manner represented by the dotted lines, to
supply the burner. H, H, a pipe or tube to pass either into a chimney or to the
exterior of the building, to be made sufficiently wide at the bottom to admit
as much air as may be necessary to prevent too strong a draft, and to pass
sufficiently low over the glass to prevent the escape of gas or foul air, which
by that means would be conveyed out of the building.
In witness whereof, I, the said Isaac Hadley Reddell, have hereunto
set my hand and seal, this Twenty-sixth day of November, in the
year of our Lord One thousand eight hundred and sixteen.
