1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
The present invention relates to igniting apparatus for petroleum or similar
gas motors and its object is to permit the employment of an ordinary petroleum or
other suitable lamp with circular wick in combination with a porcelain igniting tube.
While the platinum and other metal igniting tubes used up to the present have
required a very large and intense flaine to produce the required heat, in this instance
the small flame of an ordinary petroleum lamp will be sufficient. The porcelain tube
is passed through the chimney of the lamp immediately above the place where the
chimney is contracted, and the flame is so regulated that it only touches the porcelain
tube with its extreme point as otherwise the heat would not be sufficient and lamp-
black would settle upon it.
The reservoir of the lamp is fastened in any suitable manner and on this is placed
the gallery in which the chimney rests on a suitable spring.
The chimney consists of two parts, a lower one of glass and an upper one of metal
which is rigidly fastened and provided with a flange at its lower end against which the
lower one bears just over the point where it is contracted, under the influence of the
above mentioned spring in the gallery. The porcelain tube passes through the upper
or metal part of the chimney immediately above the flange and as porcelain is a bad
conductor of heat, the heat emanating from the flame of the lamp will be concentrated
almost solely on that part of the tube which is touched by the Hame. Thus this part
of the tube will attain a sufficiently high degree of temperature for igniting the com-
bustible petroleum or other suitably combustible gas mixture which is pressed into it.
The lower or glass part of the chimney is protected against breakage through jars or
jerks by being placed on the spring inside the gallery.

COMPLETE SPECIFICATION.
Improvements in or relating to Igniting Apparatus for Gas Motors.
A communication from EMIL CAPITAINE, of Berlin, in the German Einpire,
Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 :-
The present invention relates to igniting apparatus for petroleum or similar gas
motors and its object is to permit the employment of an ordinary petroleum or other
suitable lamp with circular wick in combination with a porcelain igniting tube.
While the platinum and other metal igniting tubes used up to the present have
required a very large and intense flame to produce the required heat, in this instanco
the small flame of an ordinary petroleum lamp will be sufficient. The porcelain tube
is passed through the chimney of the lamp immediately above the place where the
chimney is contracted and the flame is so regulated that it only touches the porcelain

page_text: tube with its extréme point as otherwise the heat would not be sufficient and lamp-
black would settle upon it.
The reservoir G of the lamp is fastened in any suitable manner on the tube H and
on this is placed the gallery L in which the chimney 1) rests on a suitable spring F.
The chimney consists of two parts lower one D of glass and an upper one J of
metal which upper one is rigidly fastened and provided with a flange i at its lower
end against which the lower one bears just over the point where it is contracted, under
the influence of the above mentioned spring F in the gallery L. The porcelain tube C
passes through the upper or metal part of the chimney immediately above the con-
traction so that it can be reached by the flame and as porcelain is a bad conductor of
heat the heat emanating from the flame of the lamp will be concentrated almost solely
on that part of the tube which is touched by the flame. Thus this part of the tube
will attain a sufficiently high degree of temperature for igniting the combustible
petroleum or other suitably combustible gas mixture which is pressed into it at B.
The lower or glass part of the chimney is protected against breakage through jars or
jerks by being placed on the spring inside the gallery. The combination of the
porcelain tube C with the lamp chimney has for its object to arrange the said tube
directly over the contraction and thereby cause au ignition without using a benzine or
other spirit lamp.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, us communicated to me by my
foreign correspondent, I declare that what I claim is :-
The combination of a porcelain tube with an ordinary petroleum wick lamp in such
manner that the porcelain tube C directly above the contraction of the lamp chimney
extends across the latter and the portion D between the parts J and G is held by a
spring so that it cannot be injured even if the machine gets a shock as it is very
liable to do substantially as herein described and illustrated in the accompanying
drawings.
