Improvements in and relating to the Treatment of Gas for
Illuminating and other Purposes.
We, CHARLES EDWARD BOTLEY, and CHARLES FREDERIC BOTLEY, Junior,
both of "Guildables" Wellington Road, Hastings, in the County of Sussex,
England, Civil Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the treatment of gas, either in the process of manufacture
or in the distribution of same, whereby naphthalene and like deposits are prevented,
and the illuminating power of the gas can be increased.
We are aware that volatilised hydro-carbons have been mixed with gas to
prevent naphthalene deposits, and for increasing the illuminating power of the gas
but the process has proved ineffectual in so far as preventing the naphthalene
deposits, as hydro-carbon in this condition has very slow action on naphthalene
and moreover carries moisture which is an accepted cause of the deposits.
Now according to our invention we overcome this disadvantage by the production
of an oil or hydro-carbon mist of suitable specific gravity, within a vessel, through
which the gas to be carburated is constantly passed, so that the mist or hydro-
carbon particles can be taken up by the gas in proportion to its specific gravity,
and thereby prevent the formation of any deposits, as the action of the hydro-
carbon produced in this manner absorbs or dissolves the naphthalene or like
deposits.
This we effect by passing the gas to be treated through a vessel at one end of
which are atomizers for producing in the form of mist any suitable oil light enough
to be suspended by the gas, such as from 650 to 980 specific gravity. The said
atomizers may be operated by either compressed air, gas, or superheated steam and
is constructed so that the hydro-carbon material and the supply of pressure can be
proportionately regulated.
They each consist of a tubular body provided with suitable inlet branches one
of which communicates with a emaller tube arranged within said body to convey
the oil, whilst the other communicates with the annular space between said tube
and the body and forms a passage way for the supply of pressure. The combined
oil and pressure then enter an expansion chamber and finally pass through a nozzle
carrying a striking plate to complete the atomization of the liquid.

Illuminating and other Purposes.
We, CHARLES EDWARD BOTLEY, and CHARLES FREDERIC BOTLEY, Junior,
both of "Guildables" Wellington Road, Hastings, in the County of Sussex,
Civil Engineers, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to the treatment of gas either in the process of manu-
facture or in the distribution of same, to prevent the formation of naphthalene and
like deposits, and at the same time if required increase its illuminating power.
According to our invention we find that to effectually prevent the formation of
naphthalene and like deposits and to absorb or dissolve any deposits which may
exist, it is necessary to saturate the gas with an oil or liquid hydro-carbon in the
form of a very fine mist light enough to be readily suspended and carried
by the gas.
This we effect by passing the gas to be treated through a vessel at one end of
which is one or more specially constructed atomizers for producing the hydro-
carbon mist, so that the gas will thus carry a certain amount of oil in mechanical
suspension, the degree of saturation varying according to the specific gravity
of the gas, that is to say in cold weather more oil is used than in warm weather.
It is essential to the proper working of the process, that the gas shall be treated
with the atomized oil, at a temperature as near as possible to that of the gas in
the mains, and that the apparatus shall be so formed as to render the working of
the atomizer visible, also that the oil shall be thoroughly strained before
it is used.
Any suitably liquid hydro-carbon from 650 to 980 specific gravity, may be used,
but we have obtained excellent results from American lamp oil of 790 to 810 specific
gravity.
The atomizer may be operated by either, compressed air or gas, or super-heated
steam, and it is so constructed that the hydro-carbon material and the supply of
pressure can be proportionately regulated.
In the accompanying drawings-
Figure 1, is a plan, partly in section, shewing the carburator connected with the
gas main, and the position of the atomizer.
Figure 2, is a sectional view of the atomizer.
Figure 3, shews the striking plate of same.
Figure 4, is a detail, and
Figure 5, a section through x-x of Figure 1.
In carrying out our invention we provide a cylindrical metallic vessel such as A,
having suitably glass covered windows B through which the interior of said vessel
can be inspected, and also inlet and outlet branches C and C¹ respectively,
connecting with the gas main D. Each of these branches is provided with a
valve E, so that communication between the vessel A and the gas main, can be
shut off when desired, in which case the bye-pass valve F on the gas main is
opened, but when the apparatus is in use the valve F is closed, and the valves E
and E are open.
The atomizer G is arranged at the end of the vessel A nearest the inlet
branch C, and is attached to the said vessel by a coupling H and suitable fittings.
It is composed of the tubular body I within which the tube J is suitably suspended
in order to form an annular space K between said tube and the body I. An oil

page_text: supply pipe L fitted with a regulating cock M connects with said body and
communicates with the interior of the tube J. The pipe N for the supply of
pressure is provided with a regulating cock O, and also connects with the body I,
but communicates with the annular space K. An expansion chamber P in which
the oil and pressure combine is formed at the extremity of the tube J and connects
with the nozzle Q having a perforated striking plate R at its outer end, to complete
the atomization of the liquid. A cock S is attached to the end of the tubular
body I in order that the tube J may be cleared of any foreign matter should such
an operation be necessary. A small flange T projects into the branches C and C¹
to prevent over saturation of the gas, and also, prevent any liquid oil from
entering the mains. A well U provided with a draw off tap V is formed in the
lower portion of the vessel A to receive the drip from the atomizer and any
superfluous oil in said vessel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
Firstly. The particular process and apparatus in connection therewith, for the
treatment of gas for illuminating and other purposes, substantially as and for the
purposes herein set forth.
Secondly. In the treatment of gas for illuminating and other purposes, the
combination with a vessel such as A of an atomizer G, composed of the tubular
body I in which the tube J is suspended to form the annular space K, the supply
pipes L and N connected with said body and fitted with regulating cocks; the
expansion chamber P and nozzle Q provided with a striking plate R, with or
without the clearance cock S, and suitable coupling for attachment to said
vessel A, substantially as and for the purposes herein fully explained and as
illustrated.
