Apparatus for Heating the Igniting Tubes of Gas Motor Enginés.
I, CHARLES DENTON ABEL of No. 28 Southampton Buildings Chancery Lane in
the County of Middlesex Consulting Engineer and Patent Agent do hereby declaro
the nature of this invention to be as follows:-
This invention relates to apparatus for externally heating the tubes by means of
which the combustible charges of motor engines are ignited, and it has for its object
to effect such heating by the combustion of vapour produced by the volatilisation
of benzine or other volatile combustible liquid. For this purpose a closed receptacle
of spherical or other shape charged with combustible liquid is fitted at top with, a
tube reaching down inside the same to near the bottom and having an internal
screwed thread through which is screwed a screw rod the lower end of which acts
as a valve for more or less closing a small opening at the bottom of the receptacle,
through which the combustible liquid can pass in regulated quantities into a pipe
conducting it downwards to a point where external heat is applied for volatilizing
the liquid as it flows down. The resulting combustible vapour then passes through
a continuation of the pipe to a nozzle or Bunsen's burner where it mixes and enters
into combustion with the air. For heating the said pipe any convenient source of
heat may be used, such as part of the heat produced by the combustion of the
vapour itself, or the heat radiated from the motor engine, but by preference the
necessary heat is supplied by fixing or forming round the supply pipe a small annular
chamber having at top a number of small jets and communicating by a small hole,
regulated by a screw plug, with the interior of the pipe so that a portion of the
vapour generated passes into the annular chamber and issues through the jets thereof.
In order to produce the requisite quantity of vapour for supplying these jets in the
first instance, a cup is fixed on the supply pipe underneath the annular chamber,
for the reception of a small quantity of volatile combustible liquid which is ignited.:

Apparatus for Heating the Igniting Tubes of Gas Motor Engines.
I, CHARLES DENTON ABEL, of No. 28 Southampton Buildings, Chancery Lane, in
the County of Middlesex, Consulting Engineer, and Patent Agent, 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 externally heating the tubes by means of
which the combustible charges of motor engines are ignited, and it has for its object
to effect such heating by the combustion of vapour produced by the volatilisation of
benzine or other volatile combustible liquid. For this purpose a closed receptacle
of spherical or other shape charged with combustible liquid is fitted at top with a tube
reaching down inside the same to near the bottom and having an internal screwed
thread through which is screwed a screw rod the lower end of which acts as a valve
for more or less closing a small opening at the bottom of the receptacle, through which
the combustible liquid can pass in regulated quantities into a pipe conducting it
downwards to a point where external heat is applied for volatilizing the liquid as it
flows down. The resulting combustible vapour then passes through a continuation of
the pipe to a nozzle or Bunsen burner where it mixes and enters into combustion with
the air. For heating the said pipe any convenient source of heat may be used, such
as part of the heat produced by the combustion of the vapour itself, or the heat
radiated from the motor engine, but by preference the necessary heat is supplied by
fixing or forming round the supply pipe a small annular chamber having at top a
number of small jets and communicating by a small hole, regulated by a screw plug,
with the interior of the pipe, so that a portion of the vapour generated passes into the
annular chamber and issues through the jets thereof.
In order to produce the requisite quantity of vapour for supplying these jets in the
first instance, a cup is fixed on the supply pipe underneath the annular chamber, for
the reception of a small quantity of volatile combustible liquid which is ignited.
The said apparatus may be used in combination with any form of Buusen or other
burner and igniting tube; the accompanying drawing shews an arrangement thereof

page_text: in combination with the construction of igniting tube and Bunsens burner described
in the Specification to Patent No. 11444 of 1887.
R is a closed reservoir charged with combustible liquid having an opening at top
fitted with a tubular plug through which is screwed the rod t whose lower end
closes more or less the small opening leading into the pipe w with shut-off cock m.
The lower end of the pipe is bent upward and fixed in the nozzle a of the Bunsens
burner to the igniting tube. At p an annular chamber is fixed on the pipe u which
communicates therewith by a small hole regulated by a screw plug q and which has
several small jets at top, so that some of the combustible vapour will pass from u
into P and being ignited on issuing from the jets, will heat the pipe so as to convert
the whole of the descending liquid into vapour, which passes up into the burner where
it mixes with the air and is burnt as already described.
Below the chamber p is a cup o for the reception of a small quantity of inflammable
liquid for heating the pipe on starting.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use in combination with burners for heating the igniting tubes of gas
motor engines, of apparatus consisting of a closed receptacle charged with volatile
combustible liquid having a screw plug for regulating the flow of the said liquid
down a pipe connected to the said burner, which pipe is heated externally so as to
volatilize the liquid therein before it reaches the burner, substantially as herein
described.
2. In combination with the apparatus referred to in the preceding claim, the use
of a burner surrounding the said pipe and communicating with the same so that
a portion of the vapour passes from the pipe to the burner and serves to heat the
same, substantially as herein described.
