PROVISIONAL SPECIFICATION.
Improvements in and connected with Petroleum Oil Engines. -
JAMES CARTER, SIDNEY CARTER, FRANK CARTER, EVERSHED CARTER,
trading as Carter Bros. Engineers. Billingshurst Sussex, do hereby declare the
nature of this invention to be as follows:-
The manner of heating the vaporizer which is a chamber surrounding the ignition
tube the lamp for heating which at the same time heats the vaporizer. After the
engine is started the heat is maintained by the exhaust being circulated through a
passage which entirely surrounds the vaporizing chamber.
The oil necessary for each explosion is pumped into the vaporizer by a small pump
coupled to the exhaust lever, a portion of the air is drawn through and mixed with
the vapor the amount of air so drawn being regulated by a valve in the main air
supply passage. The manner of obtaining the air blast for lamp is by means
of a small double acting pump the piston of which is made with longitudinal slots
in which works an excentric fixed to a spindle working through the side of cylinder
and driven by skew spur gearing from the side shaft. The spindle is extended so
that a handle may be used for working the pump before the engine is started.

WAY
We, JAMES CARTER, SIDNEY CARTER, FRANK CARTER, and, EVERSHED
CARTER, trading as Carter Bros., Engineers, of Billingshurst, in the County of
Sussex, 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 :-
"Our invention relates to engines operated by the explosion of mixtures of hydro-
carbon vapour and air, the said invention consisting in the novel arrangement of the
vaporizing apparatus and of the igniting tube in connection therewith as: hereinafter
more particularly described.
In the accompanying drawings,
Figure 1 is a sectional elevation of apparatus constructed, according to our.
invention;::
'
Figure 2 is a sectional elevation of a modified form of apparatus:
Figure 3. is a section on the line 3—3, Figure 2; and,
Figure 4 is a view of another modification...
Similar letters of reference indicate corresponding parts in the several figures....
a is the power cylinder of the engine, and bis the vaporizing chamber which is
formed by a casing & having passing through it a tube d which forms the chimney.

page_text: of the lamp e, the space between the casing c and the tube being very narrow so
as to afford a very large heating surface relatively with the contents of the said
chamber b.
fis the pipe through which the liquid hydrocarbon is injected into the vaporizing
chamber b, and g is a chamber which we term the mixing chamber in which the
air admission valve h is placed, the said mixing chamber g at one end communi-
cating with the atmosphere through the aperture i and at the other end with the
vaporizing chamber 6 through the passage j.
k is the igniting tube which communicates with the interior of the cylinder in
the usual manner.

1 is a tube surrounding the oil inlet pipe and extending into the vaporizing
chamber b so that a space m is formed between the pipe and the tube 1, which
space communicates with the atmosphere through an aperture n.
In the operation of our apparatus the required quantity of oil is injected into the
vaporizing chamber 6 where it comes into contact with the hot walls of the tube d,
whereby it is vaporized, and on the outstroke of the engine the air valve opens so
that the hydrocarbon vapour is drawn from the vaporizing chamber 6 together with
the small quantity of air which enters through the aperture n into the mixing chamber
where it meets the necessary quantity of air drawn through the aperture i for
forming the explosive charge which thence passes into the cylinder.
is
In the arrangement of our invention shewn in Figure 1 the exhaust passage
represented as being formed in the casing c and as extending around the vaporizing
chamber b so that the heat of the exhausted products of combustion will tend to
raise the heat of the vaporizer. In the said Figure 1 o indicates the exhaust valve
and p the passage surrounding the vaporizer through which the products of
combustion are exhausted. In this figure also we have represented a valve q as
being arranged in the mixing chamber g for the purpose of controlling the quantity
of air which enters through the aperture i to mingle with the hydrocarbon vapour.
We have also represented the igniting tube k as extending horizontally through
the chimney d'and the said chimney as being provided with a cap r for retarding
to a certain extent the flow of the heat of the lamp through the said chimney.
In the modification of our invention shewn in Figures 2 and 3, the outer casing o
of the vaporizer is represented as extending through a chambers in direct com-
munication with the interior of the cylinder a whereby the heat of the vaporizing
chamber is largely increased by the heat due to the explosions within the cylinder.
In this modification also the inner tube d of the vaporizer is represented as provided
with ribs t, which cause the hydrocarbon vapour to pass down one side of the
vaporizing chamber and up on the other side on its way to the passage j and to the
mixing chamber g as indicated by the arrows in Figure 2.
In the arrangement shewn in Figure 4 the igniting tube k, instead of extending
horizontally across the tube d, extends longitudinally through the same, the lamp e
being placed at oue side of the chimney instead of directly beneath it.
:
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. In an engine operated by the explosion of mixtures of hydrocarbon vapour
and air, a vaporizing chamber the inner wall of which is formed by a tube through
which the heated products of combustion from a lamp pass and through which the
igniting tube extends, substantially as described.
2. In an engine operated by the explosion of mixtures of hydrocarbon vapour
and air, the combination with a vaporizer having a central tube heated by a lamp
and having the igniting tube passing through it, of a passage formed around the
Baid vaporizer through which the products of combustion from the power cylinder
are exhausted, substantially as, and for the purpose, described.
3. In an engine operated by the explosion of mixtures of hydrocarbon vapour
and air and in which the vaporizer is provided with a central tube through which the

page_text: igniting tube also passes, arranging the said vaporizer in a box or chamber in
communication with the interior of the cylinder, substantially as described.
4. In an engine operated by the explosion of mixtures of hydrocarbon vapour
and air, a vaporizing chamber the inner wall of which is formed by a tube through
which the products of combustion of the heating lamp pass and having the igniting
tube extending longitudinally through it, substantially as described.
