1. FREDERICK THOMAS SCHMIDT, of Hustlergate Bradford in the County of York,
Electrician, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of an apparatus whereby gas jets
in lamps and other places may be lighted or extinguished from any place to which a
connection is made."
I accomplish my object in the following manner. The apparatus is fixed to the
service pipe, and consists of a short pipe containing a valve, on the spindle of which
is a lever extending on both sides of the centre of the valve spindle. To the said
short pipe are fixed two plates, to one of which are secured two magnets, and below
each magnet is a bar mounted on trunnion pins which allow the respective bar
to move when an electric current is sent through the adjacent magnet.
When lighting a gas flame an electric current is sent through the magnet on one
side of the short pipe and valve, which causes the respective bar which for distinction
I call the hinged bar to move on its trunnions and an armiture on the said bar to
come in contact with the valve lever, thereby opening the valve for gas to pass to the
burner. By moving the hinged bar as described, it is brought in contact with a
vertical bar raising the same a sufficient distance to break contact; then the hinged
bar drops, and the vertical bar again brought into contact by a spring, when the
hinged bar on trunnions is again lifted and the contact broken; so that a quick
vibrating motion to the hinged bar and vertical bar is obtained; by which electric
sparks are almost continuously passing between the vertical bar and its metallic
contact as the former is raised and the circuit broken: so that gas escaping from
the burner and impinging on the before mentioned contact is lighted by the electric
sparks.
To extinguish the flame or gas light, a current is sent to the magnet on the opposite
side of the pipe and valve, by which the adjacent hinged bar on its trunnions is
attracted towards the magnet, and the valve closed by an armiture coming in contact
with the valve lever.

Distance.
I, FREDERICK THOMAS SCHMIDT of Hustlergate, Bradford, in the County of York
Electrical 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:-
:
This invention has for its object the construction of an apparatus whereby gas jets
in lamps and other places may be lighted or extinguished from any place to which a
connection is made and consists of a short pipe containing a valve which is opened
and closed by an electric current being sent to the respective electro magnets attached
to the said pipe the electro magnet on one side in addition to opening the gas valve,
operates a vertical bar, causing the same to break circuit or contact in quick succession
so that sparks are almost continuously passing between the vertical bar and its
metallic contact maker, that gas escaping from a burner and impinging on the
before mentioned contact is lighted by the electric sparks: the gas flame being
extinguished by sending a current through the electro magnet at the opposite end of
the gas valve lever.
In order to more fully explain my apparatus, I will describe the same by making
reference to the accompanying sheet of drawings which form part of this specification,
and in which Fig. 1 represents an elevation of my invention drawn to a scale of about
double the original size, and Fig. 2 an elevation looking at right angles, that is, in
the direction of the arrow: the casing enclosing the electro inagnets is shewn in
section in both figures.
The apparatus has an internal thread at A, and is screwed on the service pipe which
then forms a continuation to the burner B. In the pipe immediately above the base
plate C, is a circular valve D, having a lever D₁ secured thereto the arms of which
extend on both sides of the centre: and to the upper plate C¹ I secure two electro
magnets E and E', below each of which are mounted the bars or armatures F and F¹
respectively, each bar or armature being hinged or mounted on trunnion pins so that
when an electric current is sent through the adjacent electro magnet, the respective
bar or armature is operated.
To open the valve D for allowing gas to pass to the burner B and for lighting same,
an electric current is sent from any distance in connection therewith, through the
electro magnet E fixed on one side of the valve, the electro magnet attracting the
hinged armature or trunnioned bar F, causing an arm H on the said armature or bar F
to come in contact with one end of the valve lever D₁, thereby turning the circular
valve D to allow gas to pass to the burner B.
By moving the hinged bar or armature F as described, it is brought in contact with
a sliding bar J projecting vertically, by which it is raised a sufficient distance for the
same to break circuit or contact-with-a metallic-projection at J'. As soon as the

page_text: circuit is broken, the hinged bar or armature F drops, and the bar J is brought into
circuit or contact again by the pressure of spring S on the bar J, and when the circuit
is complete, the hinged bar or armature F is attracted and the circuit broken as
before thus causing a quick vibrating motion to be given to the hinged bar F and
bar J, by which electric sparks are caused to pass almost continuously between the
bar J and its metallic contact J', as the former is being raised in rapid succession to
break the circuit: so that on gas escaping from the burner and impinging on the
before mentioned contact, it is lighted by the electric sparks.
To extinguish the flame or gas jet, an electric current is sent to the electro magnet E¹
placed on the opposite side of the valve, by which the adjacent hinged bar or armature F
is attracted towards the electro magnet, and the valve closed by an arm H¹ on the
hinged bar or armature F' coming in contact with the gas valve lever D', thus stopping
the supply, thereby extinguishing the flame.
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 :-
The combination of an electro magnet E' with a hinged bar or armature F, bar J,
and metallic projection J', all arranged substantially in the manner and for the purpose
shewn and described.
The hereinbefore described process of lighting gas jets, the essential novelty in such
process consisting in the operation of the bar J in a vertical direction for breaking in
rapid succession the circuit or metallic contact.
