AN IMPROVED ARRANGEMENT OR REGULATOR FOR GAS LIGHTS, WHEREBY A MORE PERFECT COMBUSTION IS ATTAINED
Year: 1875

page_text: COMPLETE SPECIFICATION filed by Samuel Chandler at the Office of
the Commissioners of Patents, with his Petition and Declaration,
on the 16th October 1875, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
CHANDLER, junior, of the Firm of Chandler & Sons, of York Street,
Southwark, in the County of Surrey, Gas Engineers, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
ARRANGEMENT OR REGULATOR FOR GAS LIGHTS, WHEREBY A MORE PERFECT
COMBUSTION IS ATTAINED," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the true and
first Inventor thereof.
NOW KNOW YE, that I, the said Samuel Chandler, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed in and by the following
statement :-
The object of this Invention is to improve the present system of the
combustion of gas in gas burners, and relates more especially to those
known as "argands."

page_text: It is a well-known fact that the more complete the combustion of gas
the greater is the brilliancy of the light, and such being the case a
saving of gas is effected through the fact of less being required to obtain
a given light.
Hitherto argands have been manufactured with orifices through them
which have been much too large for the admission of the proper quantity
of atmospheric air, and such being the case the hydrocarbon gas could
not give the actual amount of light which it otherwise would give; it is
therefore this air chamber with which I propose to deal, and in such a
manner as to cause a more perfect combustion of gas. For this purpose
I have shewn at Figure 1 of the Drawing annexed a burner A arranged
according to my Invention. This burner has a small orifice or air
passage of the exact size necessary for the most perfect combustion of
the gas which may be required, according to quantity, quality, or
pressure, as the case may be; it will be noticed that I have shewn two
means of inlet, either for vertical or horizontal fixing, marked A¹.
Instead however of constructing the aforesaid burner in the manner
described I may have the size orifice as needed fixed or arranged at the
lower end, or in the burner B, as shown at Figure 2; or the small taper
valve C at Figure 3 may be used to close or open the area for the
admittance of the right quantity of oxygen by means of being screwed
up or down the wire.
Having explained the object and manner in which my Invention is
carried into effect, I wish it to be distinctly understood that I do not
limit myself to any special manner of attaining my object, as it may be
attained in various ways; but what I do claim as my Invention is,
constructing burners with certain size orifices up the centre for the
admission of a certain amount of oxygen, or arrangements for closing,
opening, diminishing, or increasing the area for the supply of oxygen.
In witness whereof, I, the said Samuel Chandler, junior, have here-
unto set my hand and seal, this Sixteenth day of October, in
the year of our Lord One thousand eight hundred and seventy-
five.
