page_text: We, THE AUTOMATIC UNIVERSAL GAS LIGHTER, LIMITED, of Throgmorton House,
15, Copthall Avenue, in the City of London, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a modification of the arrangement of combined gas-cock,
plug and igniting-tube forming the subject of an Application for Letters Patent
filed by J. F. C. Jurgens dated 23 December 1897 No. 30437 and it consists in
so constructing the igniting tube as to form a Bunsen burner from which an
intimate and inflammable mixture of gas and air will issue upon the cock-plug
being fully turned in one direction, and will impinge upon the automatic gas
igniting body, such as for example a pillule of porous material impregnated with
spongy platinum, this effecting the ignition of the mixture of air and gas in a
quicker and more certain manner than it would a stream of gas alone and without
the need of accurate adjustment of the igniting body, thus increasing the
certainty and rapidity of ignition of the main supply of gas from the main burner.
The arrangement possesses the further advantage that the said mixture of gas and
air produces, when ignited, an intensely hot smokeless flame which, when used in
conjunction with an incandescent mantel, will raise the portion of such mantel
upon which it impinges, to a state of incandescence without smoking or blackening
it and so that the main supply of gas on coming in contact with such incandescent
portion of the mantel will be ignited thereby, practically without noise or explosion
and consequently without shock to the mantel.
The Bunsen flame from the igniting tube is automatically extinguished upon
releasing the cock plug.
As will be obvious an igniting tube constructed to form a Bunsen burner as
herein before described can advantageously be used in conjunction with gas igniting
arrangements other than that described in the prior specification above referred to.
Dated this 15th day of February 1898.

Arrangements.
A-communication from JULIUS FRIEDRICH CHARLES JÜRGEN, of 35, Oelkersallee,
Altona, Germany, Mechanical Engineer.
We, THE AUTOMATIC UNIVERSAL GAS LIGHTER, LIMITED, of Throgmorton House,
15, Copthall Avenue, in the City of London, 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 a modification of the arrangement of combined gas-cock,
plug and igniting-tube forming the subject of an Application for Letters Patent
dated 23 December 1897 No. 30437 and it consists in so constructing the igniting
tube as to form a Bunsen burner from which an intimate and inflammable mixture
of gas and air will issue, upon the cock-plug being fully turned in one direction,
and impinge upon the automatic gas igniting body, such as for example a pillule
of porous material impregnated with spongy platinum, which will effect the ignition
of the mixture of air and gas in a quicker and more certain manner that it would a
stream of gas alone, and without the need of accurate adjustment of the igniting
body, thus increasing the certainty and rapidity of ignition of the main supply of
gas from the main burner. The arrangement possesses the further advantage that
the said mixture of gas and air produces, when ignited, an intensely hot smokeless
flame which, when used in conjunction with an incandescent mantle, will raise the
portion of such mantle upon which it impinges, to a state of incandescence without.
smoking or blackening it, and so that the main supply of gas on coming in contact
with such incandescent portion of the mantle will be ignited thereby, practically
without noise or explosion and consequently without shock to the mantle. The
Bunsen flame from the igniting tube is automatically extinguished upon releasing
the cock plug.
Fig. 1 of the accompanying drawings shows in side elevation, a combined gas
cock, plug and igniting tube of the kind described in the said prior Specification
No. 30437 of 1897 but with the igniting tube constructed to form a Bunsen burner
according to the present invention.
Figs. 2 and 3 show respectively in side elevation and vertical section, the upper
portion of one construction of igniting tube according to this invention.
a is the cock casing formed with main and supplementary gas passages and
provided with an igniting tube b that branches off from the supplementary gas
passage in the cock casing and the supply of gas to which is governed by a spring
controlled plug arranged and operating in the manner described in the said former
specification.
The igniting tube according to this invention is constructed as a Bunsen burner
for which purpose its upper portion b¹ is formed with air inlet holes 62 and the
lower portion b extends upward and forms a gas exit nozzle within the upper
portion 6 so that when gas is permitted by the plug of the cock to enter the lower
portion of the ignition tube, as described in the said former specification, it will
escape upward through such nozzle and cause air to be drawn through the holes 62
whereby an intimate mixture of air and gas will be produced, which, impinging on
an automatic igniting device 63 above, will be more readily ignited by such device
than a stream of gas alone, and which, burning with a smokeless flame, will cause
the ignition of the main supply of gas in a more advantageous manner than usual.
When the plug of the gas cock is released, it will automatically cut off the supply

page_text: of gas to the ignition tube b, b¹ and automatic igniting body 63 and be turned full
on to the main burner.
The Bunsen igniting tube may be constructed in various ways. Preferably the
upper portion 6 is made separate from the lower portion b and adapted to be
slipped over the same. Figs. 2 and 3 show a construction of this kind in which
the upper portion of the Bunsen igniting tube consists of a short metal tube 61
adapted to slide fairly tightly on the lower portion of the igniting tube and
formed with air inlet apertures 62. The upper part of the tube b¹ may advan-
tageously be formed, as shown, with extensions 6+ forming a carrier or clip adapted
to support a block c of refractory material to which the automatic igniting body 63
is secured by fine platinum wires d arranged in the path of the issuing gas as
described in the Specification of Letters Patent No. 2312 of 1898. The automatic
igniting device may advantageously be made in the manner described in the
Specification of Letters Patent No. 29828 of 1897.
By the construction described a Bunsen igniting tube with carrier or clip for
the igniting body can be easily and cheaply made.
As will be obvious an igniting tube constructed to form a Bunsen burner as
herein before described can advantageously be used in conjunction with gas igniting
arrangements other than that shown in and described with reference to Fig. 1.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. A gas cock with plug and igniting tube constructed and operating as described
in the Specification of Letters Patent No. 30437 of 1897 but in which the igniting
tube is constructed to form a Bunsen burner from which an intimate mixture of
gas and air will issue and impinge upon the automatic igniting body above such
tube, substantially as herein described for the purposes specified.
2. In an automatic gas igniting arrangement, an igniting tube constructed to
form a Bunsen burner substantially as hercinbefore described with reference to
and shown in Figs. 2 and 3 of the accompanying drawings for the purposes
specified.
