Improvements in Apparatus for Turning on. Lighting, and
Extinguishing Gas at a Distance by Means of Electricity.
I, PAUL LOUIS GUYENOT, of Aix les Bains, Savoie, in the French Republic,
Doctor of Medicine, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for freeing, lighting and extinguishing gas
burners at a distance by means of electricity and more particularly to the apparatus
described in the Specification of my Patent No. 29244 dated December 10th, 1897.
It consists of an arrangement of apparatus of simpler and more economical con-
struction as well as of absolutely certain or reliable working.
The apparatus consists of, as in my previous patent, a closed chamber_com-
municating with a service pipe and the burner by means of a tube and pipe
respectively; a cap or cut off device capable of being located in the seat of the
aforesaid tube or in an adjoining seat which latter is formed at the outlet or end
of a pipe to which is connected a jack-light or pilot-light device.
The modifications carried out consist:-
In replacing the two electro-magnets originally described, by a single
one the core of which is curved so that its end is between the two
seats but above them; in combining this electro-magnet with a source of electricity
and a commutator or switch for reversing the current: in arranging in the chamber,
a permanent magnet resembling in shape a crown, affording a continuous current
in the curved narrow part of the electro-magnet.
The jack-light or pilot-device, the construction of which remains as before, has
its wires connected to the electro-magnet or its derivative branches in the ordinary
manner so that its lighter or platinum wire becomes incandescent when the electric
circuit is closed. With regard to the connections the line wires abut against and
are secured to two metal blocks situated or inserted in any suitable insulating block
or material; and the electro-magnet has the ends of its wire or solenoid attached
to the said blocks and further, the isolated wires of the jack-light are attached to
the same points.
The envelope or casing of the apparatus is formed of two stamped or moulded
shells the one enclosed within the other and secured by means of two screws in-
serted into the body of the apparatus; one of these shells remains always attached
to the apparatus whilst the other on withdrawing one of the screws can be removed
so that the connections above mentioned may be effected or examined.
Finally although the reverser-commutator or switch which is employed to reverse

page_text: the current, may be of any pattern whatever, it is preferable to form it by means
of two plate springs normally bearing upon a little brass-block connected by a
wire to the negative pole of the battery and between which is a stud which by
rotation to the left or right presses on the plate-spring in such a manner as to
cause the particular one to make contact with one or other of two outer brass-
blocks. These blocks are in metallic communication with and are connected by
a wire to the positive pole of the battery. The line wires are respectively connected
to the points of attachment of the plate-springs.
Suppose the apparatus to be in the state of rest, the hall or cap-closer being
situated in the seat and let us see how the operations of freeing and of lighting the
burner as well as closing and extinguishing the same, are performed.
In the state of rest the plate springs are approximately parallel to each other.
To free and to light the burner, the stud of the commutator or switch is caused
to put into contact the plate-spring and the brass-block which effects not only
the closing of the circuit but also causes the battery current to travel from the
battery through the at-present bent plate-spring and in this direction to pass
through the magnet and along the platinum wire of the jack-light or bye pass.
Under the influence of this current the core of the electro-magnet is magnetized
and attracts the ball which acquires the same polarity. This latter is then under
the action of the magnet one of the poles of which attracts it whilst the other
repels it. The direction of the current sent through the electro-magnet is such
that the ball is attracted by the pole. The attraction being effected at the side
of the seat it will be perceived that upon the opening of the circuit the ball will
naturally fall into the seat other than the one originally holding it, so as to close
the jack-light. Between the closing and opening of the electrical circuit, the ball
rests in neither seat and gas has free access from the service pipe to the burner
and to the jack-light or auxiliary lighting-burner the platinum wire of which latter
is rendered incandescent and under these conditions lighting of the burner is
effected.
Once the burner is lit, the ball falls back, as we have seen above, on to the seat
thus closing the auxiliary burner whilst gas continues to escape up and from the
burner.
To close the burner and put out the light the stud of the commutator or switch
is caused to act on the other plate spring putting it into contact with its block
which operation entails the closing of the circuit and reversal of the direction of
the current.
The second plate-spring being now bent, the current flows through this and
returns through the straight plate-spring which latter is the one previously bent
for the foregoing operation.
The ball is again attracted by the core and, by reason of the polarity which it
assumes, it is towards the pole of the magnet that is to say towards the seat. The
final opening of the circuit determines or causes the fall of the ball on to the said
seat and gas is completely cut off, the burner being consequently extinguished.
The above described freeing, lighting and extinguishing apparatus, may be made
any suitable size or proportions and of any convenient shape.
of
It may be used in conjunction with all kinds of gas-burners and any suitable
source of electricity may be employed to actuate the working parts of the apparatus.
Any other convenient switch or commutator than the one above described, can be
used.

Extinguishing Gas at a Distance by Means of Electricity.
I, PAUL LOUIS GUYENOT, of Aix les Bains, Savoie, in the French Republic,
Doctor of Medicine, 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 apparatus for freeing, lighting and extinguishing gas
burners at a distance by means of electricity, and, more particularly, to the apparatus
described in the Specification of my former Patent No. 29244 dated December 10th,
1897.
It consists of an arrangement of apparatus of simpler and more economical con-
struction as well as of absolutely certain or reliable working.
In the following description I refer to the annexed drawings on which ;-
Figure 1 is a vertical section on line 1-1 of Figure 2, of an apparatus of a
simplified construction for supplying lighting and extinguishing gas.
Figure 2 is a horizontal section on line 2-2 of Figure 1.
Figure 3 is a vertical section at right angles to that shewn in Figure 1, i.e. on
the line 3-3 of Figure 2.
Figure 4 is a side elevation of the apparatus with a part of its outer covering
removed and illustrates the connection of the apparatus to an electric battery and
a switch or commutator for reversing the current.
Figure 5 is a horizontal section on line 5-5 of Figure 4.
Figures 6 and 7 are diagrams explaining the working.
Figures 8 and 9 shew the reversing commutator or switch in positions corre-
sponding to those of Figures 6 and 7.
The apparatus shewn consists of, as in my previous invention, a closed chamber A
communicating with a service pipe B and the burner C by means of a tube a
and pipe a respectively; a cap or cut off device b capable of being located in the
seat of the aforesaid tube a or in an adjoining seat which latter is formed at
the outlet or end of a pipe f to which is connected a jack-light or pilot-light
device, represented as a whole, by the letter V.
The modifications effected, consist;
In replacing the two electro-magnets originally described by a single one E D
the core e of which is curved at e¹ so that its end is between the two seats c and c³
but somewhat above them; in combining this electro-magnet with a source of
electricity and a commutator or switch for reversing the current; in arranging
in the chamber A, a permanent magnet F resembling in shape, a crown, affording
a continuous current in the curved narrow part of the electro-magnet E D.
The jack-light or pilot-device, the construction of which remains as before, has
its wires connected to the electro-magnet or its derivative shunt branches in the
ordinary manner so that its lighter or platinum wire becomes incandescent when
the electric circuit is closed. With regard to the connections, the line wires .r
and abut against and are secured to two metal blocks y and y' situated or
inserted in any suitable insulating block or material Y; and the electro-magnet E D
has the ends of its wire or solenoid attached to the said blocks at and ¹, and
further, the isolated wires of the jack-light are attached to the same points as
shewn on Figures 4 and 5.
It will further, be remarked that the envelope or casing of the apparatus is
formed of two stamped or moulded shells X and X' the one enclosed within the

page_text: other (Figures 2 and 5) and secured by means of two screws and inserted into
the body of the apparatus; one of these shells X is permanently attached to the
apparatus whilst the other X¹, on withdrawing one of the screws v vl, can be
removed so that the connections above mentioned may be effected or examined.
Finally, although the reverser-commutator or switch M which is employed to
reverse the current, may be of any pattern whatever, it is preferable to form it
(Figure 4) by means of two plate springs and normally bearing upon a little
brass-block n connected by a wire to the negative pole of the battery N and
between which, is a stud which by rotation to the left or right, presses on the
plate-spring or the other in such a manner as to cause the particular one to
make contact with the brass block or terminal n' or n². These blocks or terminals
are in metallic communication with and are connected by a wire to the positive
pole of the battery N. The line wires and are respectively connected to the points
of attachment of the plate-springs and .
Suppose the apparatus to be in the state of rest, the ball or cap closer 6 being
situated in the seat e, Figure 1, and let us see how the operations of freeing and
lighting the burner as well as closing and extinguishing the same, are performed.
In the state of rest the commutator or switch M occupies the position shewn
on Figure 4.
To free and to light the burner, the stud 12 of the commutator or switch M is
caused to put into contact the plate spring with the terminal n¹ which effects not
only the closing of the circuit but also causes the battery current to travel from
the battery N in the direction indicated by the arrows in Figure 8 and in this
direction to pass through the magnet E D and along the platinum wire of the
jack-light or bye-pass V.
Under the influence of this current the core e e¹ of the electro-magnet is mag-
netized and attracts the ball which acquires the same polarity. This latter is
then under the action of the magnet F (Figure 6) one of the poles of which
attracts it, whilst the other d repels it.
The direction of the current sent through the electro-magnet is such that the
ball is attracted by the pole . The attraction being effected at the side of the
seat c¹, Figure 6, it will be perceived that upon the opening or breaking of the
circuit the ball will naturally fall into the seat c' so as to close or cut off the jack-
light. Between the closing and the opening of the electrical circuit, the ball b
rests in neither seat and gas has free access from the service pipe B to the burner C
and the jack-light or auxiliary lighting-burner V, the platinum wire of which
latter is rendered incandescent, and under these conditions lighting of the burner
is effected.
Once the burner is lit, the ball falls back, as we have seen above, on to the
seat thus closing the auxiliary burner V whilst gas continues to escape up and
from the burner C.
To close the burner and put out the light the stud 2 of the commutator or
switch M is caused to act on the other plate spring putting it into contact with
its terminal which operation entails the closing of the circuit and reversal of
the direction of the current, as illustrated on Figure 9.
The ball is again attracted by the core o el and, by reason of the polarity which
it assumes, it is attracted towards the pole d of the magnet (Figure 7) that is
to say towards the seat c. The final opening of the circuit determines and causes
the fall of the ball on to the said seat, and gas is completely cut off, the burner C
being consequently extinguished.
The above described freeing, lighting and extinguishing apparatus, may be
made of any suitable size or proportions and of any convenient shape.
It may be used in conjunction with all kinds of gas-burners and any suitable
source of electricity may be employed to actuate the working parts of the apparatus.
Any convenient switch or commutator other than the one above described, can be
used,

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I claim
is:-
1. An apparatus for freeing, lighting and extinguishing gas at a distance by
electricity, which is characterised by the combination of a closed chamber A in
communication with the service pipe by means of a tube a and with a gas-burner
through a small pipe a¹; of a jack-light V communicating with the said chamber
and furnished across its orifice with a platinum wire; of a cap or ball 6 capable
of being located in the seat c which terminates the tube a, or in the seat c¹ of the
pipe leading to the jack-light V; of an electro-magnet E D situated in an elec-
trical circuit within which is keyed or placed any suitable commutator or switch
for reversing the current; and of a circular permanent magnet F whose magnetism
is cpposite to that of the core of the electro-magnet E D, substantially as and for
the purposes described.
2. The apparatus for freeing lighting and extinguishing gas burners at a dis-
tance by means of electricity, being an improvement on the apparatus described
in my Patent No. 29244 of 1897, constructed, combined, and arranged to operate,
in the manner herein set forth.
