COMPLETE SPECIFICATION (AMENDED).
An Improved Igniting Attachment for Gas-burners.
I TIMOTHY VINCENT RIORDAN, of No. 63, Elms Road, Clapham, London, S.W.
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 relates to an attachment for gas-burners, whereby the coal-gas.
issuing from same, may be ignited by its chemical action upon a medium held by
such attachment.
One part of my invention relates to an improvement in the method of attachment,.
and another part to an improved igniter.
And in order that the said invention may be the more readily understood and
carried into effect, I have referred to same upon the accompanying sheet of
illustrative drawings, wherein:
Fig. 1 is a perspective view of the attachment, without the igniting medium,
Fig. 2 a side elevation of an ordinary gas-burner, with the complete attachment
in position thereon.
Fig. 3 a plan view of Fig. 2, and
Fig. 4 a side view of the igniting medium shewn separate.
The nature of the attachment is as follows:-
:-
I form of suitable resilient material, a spring clip a having open ends, which clip.
is adapted to be slipped over or around an ordinary gas-burner b, and be securely
maintained in position thereon.
At the top of this clip a and attached thereto, I fix a small holder
rounded or
turned in the opposite direction, which holder is designed to receive a suitable
igniting medium, such as that hereinafter described.
The attachment can be adjusted so that the igniter may just catch the bottom of
the stream of gas issuing from the burner.
The material or composition of my improved igniter, is made of a mixture of
platinum black, white clay, and flint powder, in or about the proportion of one part
of each, thoroughly mixed together and then moulded into plugs or pellets of the
required dimensions. I afterwards fire the plugs in a furnace at a high temperature.
(such as a furnace for pottery), which renders them very porous.
In this plug or pellet so composed, I insert in the usual way, one or more
fine platinum wires e twisted together, and projecting from the said plug or
pellet d.
The clip a with the plug or pellet d, can be placed on any ordinary gas-burner b,
with the fine platinum wires e in close proximity to the igniting opening in the
gas-burner, so that when the coal-gas containing hydrogen is turned on and reaches

page_text: the plug or pellet, the material of which the latter is composed, is ignited through
the agency of the finely divided platinum, in the well-known manner.
I am aware that a porous plug containing finely divided platinum is not new
as for instance the invention described in the Specification of Letters Patent
granted to John Frederick Duke dated the 15th January 1895 No. 969 and
I make no general claim to an ignitor so composed.
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. An igniting plug formed by mixing platinum black with suitable materials to
form a plug, and firing the plug in a furnace to render it porous, substantially as
described.

The improved igniter for gas-burners, substantially as above described.
