Improvements in or relating to Lime-light Apparatus.
I, GEORGE WRIGHT GWYER Jr. of 64 Cotham Road, Bristol in the County of
Gloucester, Gentleman do hereby declare the nature of this invention to be as
follows:-
:-
In place of the ordinary lime light jet tray an apparatus of almost equal
portability is substituted forming a support for the lime light jet and also a
saturator which can be used with an ordinary lime light jet. The apparatus may,
by a shifting of the usual rubber tubing, be at once worked either with oxygen and
hydrogen in the usual manner or as an ether saturator in combination with oxygen
alone. The change from one form of light to the other being made without
removing either the lime light jet or any part of the apparatus from the
lantern.
In carrying out my invention I provide a flat, closed metal case, similar in shape
to an ordinary lime-light jet tray, and, preferably, about one inch in height.
This forms the saturator, the interior being divided into a series of communicating
chambers so that the gas in passing through is forced to take a zig-zag, up-and-
down or tortuous passage to ensure thorough saturation, the interior of the case
being tightly packed with suitable absorbent material. I prefer to introduce the
gas by means of a spray or perforated tube, and beneath the outlet pipe from the
saturator I place a preferably trough shaped piece of metal perforated with small
holes, and below this trough I pack similar absorbent material to that used in the
other divisions. This end chamber, which I term the buffer chamber, serves to
collect and absorb and excess of liquid hydrocarbon which may be introduced into
the saturator, and to take up any liquid which may be driven through the vessel
when an excessive pressure of gas is employed, and thus prevent it from being
driven, or escaping, into the tubes or chamber of the jet. As a further check Ĭ
may cover the gas outlet from the saturator with perforated metal, or similar
reticulate material.
At or near the back of the saturator I provide an upright rod or tube, upon
which an ordinary "jet" can be placed in the usual manner and clamped in position
by a thumb screw or similar means.
When it is desired to use the ordinary gases-oxygen and hydrogen-the
saturator taps are turned off, and the saturator not used except as a means of
support for the jet; but when it is desired to use the saturator the inlet to the
saturator and the oxygen tube of jet are connected together by india rubber tubes
and a T or in other suitable manner, and the outlet from the saturator, and
the hydrogen tube of the jet, are also connected together by rubber tubing; the
oxygen supply being introduced through the third arm of the T piece.
saturator tubes and jet may be supplied with ordinary valves or taps or screw down
valves, in order to control the supply of gas to the saturator and jet.
The
By these means any ordinary jet may be used with the saturator, and in the
event of the supply of liquid hydrocarbon or ether running short or being exhausted,
I can immediately alter the apparatus and use the ordinary oxygen and hydrogen
gases, without delay.

Improvements in or relating to Lime-light Apparatus.
I, GEORGE WRIGHT GWYER, Junr., of 64 Cotham Road, Bristol in the County
of Gloucester, Gentleman 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 :—
My invention relates to the substitution or use, in place of the ordinary limelight
jet tray, of an apparatus of almost equal portability forming a support for the lime-
light jet, and also a saturator, which can be used with an ordinary limelight jet.
The apparatus may by a shifting of the usual rubber tubing be at once worked
either with oxygen and hydrogen in the usual manner, or as an ether saturator in
combination with oxygen alone; the change from one form of light to the other
being made without removing either the jet or any part of the apparatus from the
lantern.
In carrying out my invention I construct a flat, closed metal case or box, similar
in shape to an ordinary limelight jet tray and preferably about one inch in height.
This forms the combined saturator and "tray," the interior being divided into a
series of communicating chambers so that the gas in passing through is forced to
take a zigzag, up-and-down or tortuous passage, to ensure thorough saturation by
the fluid in the vessel, the interior being tightly packed with suitable absorbent
material. I prefer to introduce the gas by means of a spray, or perforated tube,
and beneath or around the outlet pipe from the saturator I place a preferably
trough or angle shaped piece of metal perforated with small holes, whilst the
remaining portion of the division or compartment is very tightly packed with
absorbent material. This chamber, which I term the buffer chamber, serves to
collect and absorb any excess of liquid which may be introduced into the saturator,
and to take up any liquid which may be driven through the vessel, when an
excessive pressure of gas is employed, and thus prevent it from being driven or
escaping, into the tubes or chamber of the jet. As a further check I may
cover the gas outlet from the saturator, with perforated metal or similar reticulate
material.
At or near the centre of the back of the saturator I provide an upright rod or
tube to which an ordinary "jet" may be secured and held in position in any usual
manner.
When it is desired to use the ordinary gases-oxygen and hydrogen-the
saturator taps are turned off, and the saturator is not used except as a means of
support for the jet; but when it is desired to use the saturator itself, the inlet to
the saturator_any the oxygen tube of jet are connected together by india rubber
tubes and a T or Y piece, or in other suitable manner, and the hydrogen tube of
jet and the outlet from the saturator are also connected together by rubber tubing,
the supply of oxygen being introduced through the third arm of the Y piece. The
saturator tubes, and jet, may be supplied with ordinary valves or taps, or screw
down valves in order to control the supply of gas to the saturator and jet.

by which the saturator is filled with ether or other carburetting fluid. is the
inlet tube to the saturator, and e¹ is the outlet tube. These tubes have taps or
valves and e respectively applied thereto.
The interior of the vessel is divided into compartments x, by means of plates x',
secured alternately to opposite sides of the vessel, the opposite ends of these plates
extending to within a short distance of the sides of the vessel, so that an up-and-down,
zigzag or tortuous passage is formed for the passage of the fluid.
"
It will be observed, on referring to Figure 2 of the drawings, that the gas
entering the saturator through the tube f', passes through all the compartments .c
until it comes to the top or beginning of the last chamber 2, whence it passes from
the saturator by the pipe c', without passing through the remainder of
compartment x2, which I term the "buffer chamber, the object of this final
chamber being to take up any surplus liquid which may be in or forced through the
saturator, and to act in a manner as an absorbing and reservoir chamber. I prefer
that the pipes and e', where they enter and leave the chamber respectively, should
be provided with wire gauze or reticulate shields or covers. In Figure 4 fl and p
indicate one form of shield or diffuser; a perforated tube or roll 9¹ being also
provided around the filling opening g.
The method which I find convenient to employ in constructing my saturator is to
first construct the outer shell, with the exception of the wall z (Fig. 4) a compressed
layer of packing is then inserted, then a division plate is soldered in its position
above the packing, then another layer of packing, then another division plate, and so
on until the saturator is entirely full from end to end, the last or buffer chamber
being packed the tightest of all.
Upon referring to Figure 1, it will be readily seen that the vessel may be used
simply as a means of support for a jet for use with oxygen and hydrogen gases, the
jet being attached to the pin b in the usual manner; or, by connecting the tubes in
the manner shown, the vessel may be used as a saturator in conjunction with
oxygen alone, which is introduced through the tube r, attached to the Y pièce g,
part of the gas going direct to the oxygen tube of jet, by means of the
connecting tubing o, and part passing through the saturator and thence to the
hydrogen tube of jet by means of the tubing h. By employing two taps or valves
on the saturator, in addition to the jet taps, I am able to regulate the admission and
emission of gas with the greatest nicety and precision.
One of the drawbacks incidental to the use of many forms of saturators is the
necessity of employing two saturators when used in the interior of a biunial or
double lantern. I am able to employ one saturator for use with a biunial or double
lantern, because I do not in any way alter the usual connections between the
dissolving taps or taps and the jets but when I desire to use the saturator I merely
connect the outlet valve of the saturator with the hydrogen pipe of the dissolver,
the inlet tube of the saturator itself and the oxygen tube of the dissolver deriving
their joint supply of gas from a Y piece connected to an oxygen cylinder or bag or
other supply. This is shown clearly in Figure 5, wherein 1 is the hydrogen entry
tube of the dissolver, and 2 the oxygen inlet of same, 3 the Y piece leading to the
oxygen supply or cylinder, 4 and 5 inlet to and outlet from saturator respectively.
The jets are connected to the dissolver in the usual way, and never require
alteration, the saturator when used being connected directly to the dissolver and not
with either of the jets, so that the change from "saturated" to ordinary hydrogen
gas can be very easily effected, by first turning off the saturator taps, then removing
the rubber tube from the outlet tube of saturator, and connecting it to the hydrogen
gas supply or cylinder, the oxygen connections requiring no alterations, since when
the saturator taps are closed, all the oxygen gas goes direct to the dissolver, so that
only one tube has to be disconnected to make the change from one form of light to
the other.
Referring to the saturator, I do not confine myself to the precise construction

page_text: shown, as the gas passages or chambers may be formed in any other suitable way,
so long as a final reservoir, buffer, or absorption chamber or space is provided.
I am aware that it has been proposed to combine a flat saturator having two
upright tubes, with an ordinary jet, and I do not herein claim such an arrangement,
but,
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what I
claim is :-
1. In limelight apparatus, the combination of a saturator and jet substantially as
shown, and for the purpose described.
2. In limelight apparatus, a saturator with a series of gas passages, and final
reservoir or buffer chamber, substantially as described.
3. In limelight apparatus, the combination in a multiple lantern, of a saturator
such as described, with two or more jets and dissolver, the apparatus being capable
of being used, at will, with ordinary oxygen and hydrogen gases, or with oxygen
and "saturated" oxygen, substantially as described.
