IMPROVEMENTS IN APPARATUS FOR SATURATING ATMOSPHERIC AIR OR GASES USED FOR HEATING OR ILLUMINATING PURPOSES WITH LIQUID HYDRO CARBON."
Year: 1880

page_text: LETTERS PATENT to Sanders Trotman, of Mornington House, Wanstead, in
the County of Essex, Engineer, for an Invention of "IMPROVEMENTS IN
APPARATUS FOR SATURATING ATMOSPHERIC AIR OR GASES USED FOR
HEATING OR ILLUMINATING PURPOSES WITH LIQUID HYDRO CARBON."
PROVISIONAL SPECIFICATION left by the said Sanders Trotman at the
Office of the Commissioners of Patents on the 12th July 1880.
SANDERS TROTMAN, of Mornington House, Wanstead, in the County of Essex,
Engineer. "SATURATING_ATMOSPHERIC AIR OR GASES USED FOR ILLUMINATING
PURPOSES WITH LIQUID HYDRO CARBON."
My Invention consists of an improved means or apparatus for more effectually
carburetting or saturating with hydro carbon atmospheric air and other gases used
for heating or illuminating purposes, thus securing an increased degree of heating
or illuminating power.
For the purposes of my Invention I take a vessel of suitable shape and dimensions,
by preference circular, for intercepting the gas froin the meter or other source of
supply. The vessel may be made of tinned iron or any other suitable metal.
Into the aforesaid vessel the gas or atmospheric air is admitted at the bottom
and passes into a vertical tube covered by another tube of larger dimensions
working telescopically over it; attached to the bottom of this second tube, into
which the gas passes freely, is a disc of the internal diameter of the case, or nearly
so. This disc is so supported by floats as to be always resting on the surface
of the liquid hydro carbon (with which the vessel is filled) whatever its level
may be.
Thus, the gas on entering the vertical tube passes into the outer tube (working
telescopically over it), and thence laterally underneath the disc and through the
liquid hydro carbon to escape at its extreme edge. On to this edge of the disc
is soldered a flange of suitable depth to prevent the escape of the gas otherwise
than through a series of small holes round its extremo circumference, thus

page_text: attenuating the bubbles or streams of gas and perfecting the saturation. To aid in
accomplishing this result I also place a second or inner flange between the centre
and outer circumference, similarly perforated or spaced out from the disc, so as to
leave an annular space or thoroughfare of such width as shall be equivalent in
area to the thoroughfare of the inlet pipe of the apparatus; this arrangement
effectually disperses the gas through the liquid and compels a perfect saturation
thereof.
The larger tube, before referred to as working telescopically over the standard or
inlet tube, is closed at the top, and to allow of its change of position vertically with
the rising or falling of the disc a chamber of suitable size is placed on the top of
the vessel, hereinbefore described, and receives the gas which has been saturated
and has escaped from its immersion through the perforations to the upper side of
the-disc-and-thus-to-the-top of the vessel
The outlet is placed on the top of the chamber thus described.

SANDERS TROTMAN, of Mornington House, Wanstead, in the County of Essex,
Engineer. "IMPROVEMENTS IN APPARATUS FOR SATURATING ATMOSPHERIC AIR
OR GASES USED FOR HEATING OR ILLUMINATING PURPOSES WITH LIQUID HYDRO
CARBON."
My Invention consists of an improved means or apparatus for more effectually
carburetting or saturating with hydro carbon atmospheric air and other gases used
for heating or illuminating purposes, thus securing an increased degree of
illuminating power.
For the purposes of my Invention I take a vessel of suitable shape and dimensions,
by proference circular, as shewn in the Drawing, and of the proportions therein
defined, for intercepting the gas from the meter or other source of supply. The
vessel may be made of tinned iron or any other suitable metal. Into the aforesaid
vessel the gas or atmospheric air is admitted at the bottom and passes into a
vertical tube covered by another tube of larger dimensions working telescopically
over it; attached to the bottom of this second tube, into which the gas passes
freely, is a disc of the internal diameter of the case, or nearly so. This disc is
SO supported by floats as to be always resting on the surface of the liquid hydro
carbon with which the vessel is filled, whatever its level may be. Thus, the gas
on entering the vertical tubo passes into tho outor tube (working telescopically over
it), and thence laterally underneath the disc and through the liquid hydro carbon
to escape at its extreme edge. On to this edge of the disc is soldered a flange of
suitable depth to prevent the escape of the gas otherwise than through a series of
small holes round its extremo circumference, thus attenuating the bubbles or
streams of gas and perfecting the saturation. To aid in accomplishing this result I
also place a second or inner flange between the centre and outer circumference,
similarly perforated or spaced out from the disc, so as to leave an annular space
or thoroughfare of such width as shall be equivalent in area to the thoroughfare of
the inlet pipe of the apparatus; this arrangement effectually disperses the gas
through the liquid and compels a perfect saturation thereof.
The larger tube, before referred to as working telescopically over the standard
or inlet tube, is closed at the top, and to allow of its change of position vertically
with the rising or falling of the disc a chamber of suitable size is placed on the
top of the vessel, hereinbefore described, and receives the gas which has been
saturated, and has escaped from its immersion through the perforations to the
upper side of the disc, and thus to the top of the vessel. The outlet is placed on
the top of the chamber thus described.

Having now described the nature of my Invention, and the manner in which the
same is to be performed, I hereby declare-that-I-claim_as_my Invention the
saturation of the air or gases before referred to, for the purposes herein before
described (without reduction of pressure), by immersing and passing them laterally
or horizontally through the said liquid hydro carbon.
In witness whereof, I, the said Sanders Trotman, have hereunto set my
hand and seal, this Twentieth day of December, in the year of our Lord
One thousand eight hundred and eighty.
