PROVISIONAL SPECIFICATION.
Improved Means for Thoroughly Mixing the Gases for Lime Light
Production.
I GEORGE WRIGHT GWYER, Junior of 17 St. Augustine's Parade, City and
County of Bristol, Engineer do hereby declare the nature of this invention to be as
follows:-
According to the usual method of producing a mixture of oxygen and oxy-ether
gas the gases are forced through separate pipes into a circular casing or chamber
in which they become imperfectly mixed just prior to passing to the jet nipple.
The object of my invention is to improve the mixing, for which purpose
I connect the two supply pipes to a single branch which is attached to a mixing
chamber of long rectangular or equivalent shape from the opposite end of which a
curved pipe projects with a nipple end in line with the lens.
By this invention the gases strike each other at the junction of the branch and
flow along the branch in a partially mixed condition and then become thoroughly
and completely mixed in the chamber before passing through the curved pipe.
The introduction of ether saturators has rendered necessary an improvement in
the mixing of the ether gas with the oxygen. The specific gravity of the gas being
more than the hydrogen formerly used more thorough mixing is required to get
good results. This is usually accomplished by increasing the size of the existing
circular shaped mixing chamber. There is however a limit to the size of the
mixing chamber because the nipple must not be above the middle of the lenses of
the condenser.
By placing the jet horizontally it enables a great length of mixing chamber to
be obtained.
Instead of carrying oxygen and oxy-ether gas in separate pipes to the mixing
chamber as formerly the gases commingle as soon as they enter the branch before
they come to the mixing chamber and a cock can be placed at the junction by
means of which both the oxygen and the oxy-ether gas can be cut off at once, an
important thing to a lanternist when he sees that the ether in his saturator is
getting exhausted.

1, GEORGE WRIGHT GWYER, Junior, of 17 St. Augustine's Parade, City and
County of Bristol, Engineer, 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:—
According to the usual method of producing a mixture of oxygen and oxy-ether

page_text: gas the gases are forced through separate pipes into a circular casing or chamber
in which they become imperfectly mixed just prior to passing to the jet nipple.
The object of any present invention is to improve the mixing for which purpose
I connect the two supply pipes A, A, as shown in the annexed drawings, Figure 1
side elevation, Figure 2 plan, to a single branch B which is attached to a mixing
chamber or vessel C of long rectangular, circular, or equivalent shape and
preferably coned at the juncture, from the opposite end of which vessel C a curved
pipe D projects with a nipple eud in line with the lens.
By this invention, the gases from the two pipes A, A, strike each other at the
junction of the branch and flow along the branch in a partially mixed condition
and then become thoroughly and completely mixed in the chamber or vessel C
before passing through the curved pipe D.
The introduction of ether saturators has rendered necessary an improvement in
the mixing of the ether gas with the oxygen. The specific gravity of the gas
being more than the hydrogen formerly used, more thorough mixing is required
to get good results. This is usually accomplished by increasing the size of the
existing circular shaped mixing chamber. There is however a limit to the size
of the mixing chamber because the nipple must not be above the middle of the
lenses of the condenser.
By placing the jet horizontally it enables a great length of mixing chamber to
be obtained.
Instead of carrying oxygen and oxy-ether gas in separate pipes to the mixing
chamber as formerly, the gases commingle as soon as they enter the branch before
they come to the mixing chamber and a cock E can be placed that both the oxygen
and the oxy-ether gas, or either of them can be cut off at once, or regulated, an
important feature to a lanternist when he sees that the ether in his saturator is
getting exhausted.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
Connecting two supply pipes A A of a saturator of the kind described and shown
to a single pipe B in which a partial mixing of the gases can take place prior to
passing into the mixing chamber C for the more complete saturation, admixture,
commingling in proportional quantities, for improving the action on the lime at the
point of combustion, as set forth.
