PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling the Flow of and Igniting
Gas.
I, AUGUSTUS SERIN, of 4, Rue Lebeau, Brussels, in the Kingdom of Belgium,
Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for use in igniting gas by means of catalytic
materials and the like and for controlling the flow of such gas, and is chiefly
designed to provide improved means for obviating the continued exposure of
the catalytic material to the action of the gas-flame or flames proper after the
said flame or flames has or have been ignited.
For this purpose, according to my said invention, I provide a bye-pass jet the
supply of gas to which is controlled by the same cock or valve as is employed
for controlling the supply of gas to the main burner or burners, and the said
bye-pass jet is provided with a catalytic igniter of suitable construction and is
arranged so that, when ignited by the catalytic igniter, it will be in a position
to ignite gas issuing from the main burner or burners, whilst the said catalytic
igniter will be out of contact with the flame or flames from the main burner.
And I arrange the ports or passages of the said cock in such a manner that,
when the handle is in one extreme position, the gas will be shut off, when in
the other extreme position the gas will be admitted to the bye-pass, and when
in an intermediate position, the gas will be admitted to the main burner or
burners.
In carrying my said invention practice, I preferably make the bye-pass in the
form of a tube with an open end onto which fits a tubular cap having a suitable
jet or nozzle for projecting the bye-pass-flame into the path of the gases issuing
from the main burner; and to the said tubular cap is secured the catalytic
material in the form of a pastille, wire, or the like in such a position that it will
lie in the bye-pass jet but not in the flame or flames from the main burner. By
these means, when the cock is turned from the "off" position to the other
extreme position, say through an angle of 180 degrees, the bye-pass jet will be
ignited by the catalytic igniter; and when the cock is turned into an intermediate
position, the flames or flames at the main burner will be ignited by the bye-pass
flame and the bye-pass flame will be extinguished, thus preventing deterioration
of the catalytic igniter.
It is obvious that, if desired, a number of burners can be controlled by a
single cock by branching the bye-pass to each burner and providing a catalytic
igniter for each branch."

Gas.
I, AUGUSTUS SERIN, of 4, Rue Lebeau, Brussels, in the Kingdom of Belgium,
Sanitary Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to apparatus for use in igniting gas by means of catalytic
materials and the like and for controlling the flow of such gas, and is chiefly
designed to provide improved means for obviating the continued exposure of
the catalytic material to the action of the gas-flame or flames proper after the
said flame or flames has or have been ignited.
For this purpose, according to my said invention, I provide a bye-pass jet the
supply of gas to which is controlled by the same cock or valve as is employed
for controlling the supply of gas to the main burner or burners, and the said
bye-pass jet is provided with a catalytic igniter of suitable construction and is
arranged so that, when ignited by the catalytic igniter, it will be in a position
to ignite gas issuing from the main burner or burners, whilst the said catalytic
igniter will be out of contact with the flame or flames from the main burner.
And I arrange the ports or passages of the said cock in such a manner that,
when the handle is in one extreme position, the gas will be shut off, when in
the other extreme position the gas will be admitted to the bye-pass, and when
in certain intermediate positions, the gas will be admitted to the main burner or
burners as hereinafter described. By these means, all accident contingent on
explosion or occurring from the depression of the flame are removed.
-:
The improvements are illustrated in the accompanying drawing, in which :-
Figure 1 shows the cock in the position in which, by means of a notch o
arranged in communication with the lower perforation of the axial chamber of
the body or shell a of the cock, and a small passage r, the gas-supply pipe b is
connected with the bye-pass supplying the igniting flame or pilot-light. This
igniting-flame or pilot-light can be ignited by means of catalytic material or
by any other suitable means.
Figure 2 shows the cock in position for igniting. The key d is slightly turned
to the right (looking from the left), so that the pin is" withdrawn from the
shoulder on the shell of the cock. In this position of the key or plug, d, there
remains but little space communicating between the tube and the byepass j.
But at the same time, the upper way h in the plug d of the cock is caused to
partially register with the way in the body or shell of the cock leading to
the burner, so that there flows but a very small quantity of gas from the feed-
pipe to the burner. It is in this position that ignition takes place at the
main burner. There is no danger in depressing or turning down the flame,
since the quantity of gas passing is very small. This advantage is obvious when
the burner is provided with a glass or like cylinder, as it is the depression of
the flame which ordinarily causes the breaking of the glass.
Figure 3 shows the position of the cock after having been partially turned
cut of the position, shown in Figure 1. In this position, the passager no
longer communicates with the tube, this latter being closed and the pilot or
lighting-flame extinguished. On the other hand, the ways or perforations h
and in the plug d of the cock register respectively with the inlet-passage q of
of the burner and with the passage leading to the supply-pipe b, so that the
gas flows to the burner at full pressure.

Figure 4 shows the cock in its fully turned position, that is to say, the
position at which the bye-pass for the igniting as well as the passage q leading
to the burner, are closed. Said position corresponds to rotation of the plug a
through an angle of 180 degrees from its initial position shown in Figure 1.
By these means, when the cock is turned from the off" position, Figure 4,
to the other extreme position Figure 1, the jet at the bye-pass will be ignited
by the catalytic igniter; and when the cock is turned into intermediate positions,
Figures 2 and 3, the flame or flames at the main burner will be ignited by the
bye-pass flame and the bye-pass flame will be extinguished thus preventing
deterioration of the catalytic igniter.
The bye-pass is preferably provided at its end with a tubular cap having a
suitable jet or nozzle for projecting the bye-pass flame into the path of the gases
issuing from the main burner; and to the said tubular cap is secured the
catalytic material in the form of a pastille, wire, or the like in such a position
that it will lie in the bye-pass jet but not in the flame or flames from the main
burner.
It is obvious that, if desired, a number of burners can be controlled by a
single cock by branching the bye-pass to each burner and providing a catalytic
igniter for each branch.
Having now particularly described and ascertained the nature of my said
invention, and, in what manner the same is to be performed, I declare that what
I claim is:-
1. A cock provided with a bye-pass for automatic ignition, wherein the ports
or passages in the plug of the said cock are so arranged that, when the said
plug is in one extreme position, the interior of the said plug is brought into
communication with the bye-pass and with the gas-supply passage, whilst as
the plug is turned away from the said extreme position, the gas-supply to the
main-burner is opened before the passage leading to the bye-pass is closed, the
gas-passages leading to both the main-burner and to the pilot or igniting burner
being both closed when the plug of the cock is in the other extreme position,
substantially as, and for the purposes, herein before described.
2. A cock provided with a bye-pass for automatic ignition, wherein by suitably
arranging the ports or passages of the said cock, the gas-supply is brought into
communication with the igniting-passage or bye-pass in such a manner that,
by moving the key from its open position shown in Figure 1, to that where gas
is supplied to the burner, as shown in Figure 3, there is obtained an intermediate
position shown in Figure 2, whereby when the igniting passage or bye-pass is
open, the passage leading to the burner is only sufficiently open, to allow a
small quantity of gas necessary for igniting, to flow to the burner in order to
prevent the flame from being depressed or turned down.
3. The improved apparatus constructed substantially as described with reference
to the accompanying drawing, for the purposes specified.
