PROVISIONAL SPECIFICATION.
Improved Means or Apparatus for Igniting Explosive Gases in
Petroleum and other like Motors.
1, ALGERNON JASPER LYON, of 22, St. Andrew's Street, Cambridge, in the County
of Cambridge, Gentleman, do hereby declare the nature of this invention to be
as, follows:
My invention relates to an improved means in hydrocarbon engines for igniting the
explosive mixture.
To effect this object I fix to the rear end or other suitable part of the inside of the
cylinder a hollow bowl shaped plate of platinum or other suitable metal or material
having a tube or hollow neck thereto passing to the outside of the cylinder.
In the tube or neck and plate from outside the cylinder I place a smaller tube of any
suitable metal or material which is shaped to follow as much as possible the shape of
the hollow plate and reaches nearly to the end thereof and at the outside end of this
smaller tube which is fixed to the outside of the cylinder I make a vent or
exhaust hole. The hollow plate may be a disc sphere or cone, the shape being
immaterial.
The plate is, after it has been made incandescent by a blast lamp or blast gas jet,
maintained incandescent by a blast of air and benzine. An air pump actuated by any
suitable part of the engine an air vessel with a regulating pressure valve and a
reservoir for benzine being provided, the end of the blast pipe connected therewith
is fixed to the before mentioned inner tube.by a plug screw bayonet or other suitable
joint.

Petroleum and other like Motors.
I, ALGERNON JASPER LYON, of 22, St. Andrew's Street, Cambridge, in the County
of Cambridge, Gentleman, 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:-
My invention relates to an improved means in hydrocarbon engines for igniting the
explosive mixture.
To affect this object I fix to the rear end or other suitable part of the inside of the
cylinder a tube or hollow neck passing to the outside of the cylinder. In the tube

page_text: or neck from outside the cylinder I place a smaller tube of any suitable metal or
material which reaches nearly to the end thereof and at the outside end of the outer
tube which is fixed to the outside of the cylinder I make a vent or exhaust hole.
The tube is, after it has been made incandescent by a lamp or otherwise, maintained
incandescent by a blast of air and benzoline. An air pump actuated by any suitable
part of the engine, an air vessel with a regulating pressure valve, and a reservoir for
benzoline being provided, the end of the blast pipe connected therewith is fixed to the
before mentioned inner tube.
Figure 1 is an elevation and Figure 2 a section showing the igniter in place in the
cylinder.
a is the inside of the cylinder, and a¹ a boss on its wall. b is a thimble pre-
ferably made of thin platinum fixed to a tube c screwing into the cylinder wall a¹
or fitting therein with a bayonet joint. The parts b and c together make up the
outer tube. d is a vent in the tube cand e is a plug screwing into or other-
wise securely fixed to it. f is a tube fixed to the plug e and having an extension ġ
preferably of the platinum. The parts ƒ and g together make up the inner tube.
h is an open network or sponge of platinum on the end of the tube g.
In starting the whole igniter is removed the thimble 6 warmed by a lamp and
the igniter replaced. The thimble b is then kept hot by a blast of air and
benzoline vapour introduced by the tubes ƒ and g and disseminated by the sponge h
the waste vapours passing out by the vent d. The mixture of benzoline vapour and
air does not ignite or burn in the ordinary sense of the terms but coming into contact
with the hot platinum maintains it at a red heat.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I am aware that igniting tubes have before been heated from their inside and
that I make no general claim to this but what I claim is :-
1. The combination of an igniting tube with means for directing on its surface a
blast of air mixed with benzoline vapour or the like substantially as described.
2. The combination of the outer tube closed at both ends, the vent in it and the
inner tube substantially as described.
3. The combination of the outer tube, the vent near one end of it and the inner
tube reaching nearly to the outer end substantially as described.
4. Means or apparatus for igniting explosive gases in petroleum and other like
motors substantially as described and shown in the drawings.
