County of Lancaster for an Invention of "IMPROVEMENTS IN OR APPLICABLE

PROVISIONAL SPECIFICATION left by the said Thomas Taylor and John
Taylor at the Office of the Commissioners of Patents on the 27th October.

'IMPROVEMENTS IN OR APPLICABLE TO ELECTRIC GAS-LIGHTERS”
This invention relates to that class of gas lighters wherein an electric spark is
employed for lighting the gas issuing from a burner or jet, tho object of the
invention being to direct the gas exactly onto the point where the spark is
produced and thus ensure the immediate lighting of the gas by one single spark
only as well as to prevent the waste and escape of gas. By these means electric
gas lighters are enabled to be used for a much longer time without the necessity
for renewing the galvanic battery than they can be as ordinarily constructed, as it
usually requires several sparks to be emitted before the gas is lighted.
For this purpose we attach to the tube which carries the terminal wires a
hanging funnel or cone, so formed, and hung, that any gas entering the base or
mouth of the funnel is directed through the opening at the apex thereof exactly
onto the point between the two terminal wires where the spark is formed..
Thus it will be evident that, if this cone is held over the jet of gas instead of the
spark having to find the gas as usual, the gas will be caught and directed on to
the spark even though the lighter may be held slightly on one or other side of
the jet.
In constructing new gas lighters the funnel or cone may be hung direct upon
the tube which carries the wires, but for adapting this invention to gas lighters.
already constructed it may be hung from a short tube or ferrule adapted to slide
onto the outside of the ordinary tube which carries the terminal wires.

"IMPROVEMENTS IN OR APPLICABLE TO ELECTRIC GAS LIGHTERS
”
This invention relates to that class of gas lighters wherein an electric spark is
employed for igniting the gas issuing from a burner or jet, the object of the
invention being to concentrate the gas exactly onto the point where the spark is
produced and thus to ensure the immediate lighting or ignition of the gas by one
single spark only as well as to prevent the escape and waste of gas.
By these means electric gas lighters are enabled to be used for a much longer
time (without the necessity for removing the galvanic battery) than they can be
as ordinarily constructed as it frequently requires several sparks to be emitted
before the gas is lighted especially if the gas to be lighted is situated some distance
above or below the level of the eye
The improvements also allow of a spark of much shorter duration being
effectually employed whereby the life of the battery is still further prolonged.
The invention will be readily understood on referenco to to the annexed drawing
and the following explanation thereof
The drawing illustrates the application of the "concentrator" to that form of
electric gas lighter wherein the terminal wires are carried in a conducting tube a, a
but it will be evident that very slight alteration will be required to adapt the
same to other forms of electric gas lighters.
Fig. 1 is a side elevation and Fig. 2. a section of our concentrator or attachment.
We attach to the conducting tube a a or other part which carries the terminal
wires a hanging or swinging funnel or cone b, b (which we term a "Concentrator")
BO formed and hung that the apex of the cone coincides with the point where the
electric spark is produced so that any gas entering the base or mouth of the
funnel or cone 6,6 is collected and concentrated or directed through the opening c, c
at the top thereof exactly onto the apex or point between the two terminal wires
where the spark is formed.
Thus it will be evident that if this cone or concentrator is held over a jet of gas
instead of a spark having to find the gas as heretofore the gas will be caught
and directed onto the spark even though the lighter may be held slightly on one
or other side of the jet or burner and at whatever angle the "lighter" may be
held and either above or below the level of the eye as shown by the dotted lines
in Fig. 2. Fig. 3 shows the "concentrator" swinging from tubes or collars d, d.
which are so mounted that they can turn loosely on the tube a, a
The "concentrator" will also greatly facilitate the lighting of gas inside a globe
or shade with a small opening beneath, in which case we use only a section of a
cone as shown at e, e Fig. 4. To withdraw the "lighter" it should be turned partially.
round so that the swinging "concentrator" falls against the conducting tube a, a
as shown by the dotted lines.
In constructing new gas lighters the cone or concentrator may be hung direct
upon the tube or other conductor which carries the terminal wires but for adapting
our invention to gas lighters already constructed we hang it from a short open
tube or ferrule d, d adapted to slide onto the outside of the ordinary tube a, a
which carries the terminal wires and in some cases we propose to mount this short
tube loosely thereon between two collars so that it can swivel sideways as well as
swinging to and fro on the fulcrum as shown at Fig. 3.
For lighting a collection of jets known as a "Sunlight" a larger cone or
concentrator will be required.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it to be
understood that we claim as our Invention the construction and adaptation to
electric gas lighters of a hanging or swinging "Concentrator" in the form of a
cone or section of a cone so formed and hung that the apex of the cone shall
coincide with the point where the electric spark is produced substantially as and
for the purposes horeinbefore particularly set forth.
In witness whereof we the said Thomas Taylor and John Taylor have hereunto
set our hands and seals this twenty fifth day of April in the year of our Lord
one thousand eight hundred and eighty four
