Improvements relating to Oil or Hydro-carbon Motors.
JAMES EDWARDES WEYMAN GEORGE HITCHCOCK and JAMES ARTHUR
DRAKE each and all Engineers Church Acre Works Guildford Surrey do hereby
declare the nature of this invention to be as follows:-
Whereas in hydro carbon engines the ignition of the working charge has been
difficult of attaining in a simple manner, we claim to effect this in the following
manner: In our motor a vaporizer is used having an inner surface as part of or an
extension of the cylinder of the engine or motor, either as the combustion chamber
or otherwise, with an outer chamber which forms the vaporizer proper: we use a hot
tube similar to that used in gas engines, having a connection through the vaporizer
into the combustion chamber of the cylinder, the opening of the hot tube being in
the inner surface of the vaporizer: our object being to ignite the mixture where it
is richest in vapour and where it is hottest viz. in the combustion chamber or that
part of the cylinder from which the heat is taken to heat the vaporizer and which
has no water jacket, by means of a hot tube.

COMPLETE SPECIFICATION.
Improvements relating to Oil or Hydro-carbon Motors.
We, JAMES EDWARDES WEYMAN, GEORGE HITCHCOCK and JAMES ARTHUR
DRAKE, each and all Engineers, Church Acre Works, Guildford, Surrey, do
hereby declare the nature of our invention, for, "IMPROVEMENTS RELATING TO
OIL OR HYDRO-CARBON MOTORS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Whereas in hydro-carbon engines the ignition of the working charge has been
difficult of attaining in a simple manner, we claim to effect this in the following
manner.
In our motor a vaporiser is used having an inner surface as part of or an
extension of the cylinder of the engine or motor, either as the combustion chamber
or otherwise, with an outer chamber which forms the vaporiser proper: we use a
hot tube similar to that used in gas engines, having a connection through the
vaporiser into the combustion chamber of the cylinder, the opening of the hot tube
being in the inuer surface of the vaporiser: our object being to ignite the mixture
where it is richest in vapor and where it is hottest, viz. :-in the combustion chamber
or that part of the cylinder from which the heat is taken to heat the vaporiser and
which has no water jacket.
As a modification of the last named arrangement we sometimes divide the
vaporising chamber into two or more compartments, one of which compartments
being provided at the outer end of the combustion chamber is used as a reservoir
for the vapor before it is admitted into the combustion chamber or before it is
admitted into a third compartment where it is further heated by being brought into
contact with the walls of the combustion chamber immediately before it is admitted
by a suitable valve provided for the purpose.

page_text: The nature of our invention will be better understood on reference to the
accompanying sheet of drawings in which
Fig 1, is a sectional clevation and Fig. 2, a cross section of our improved
vaporiser shewing the arrangement and position of the hot tube passing through
the vaporising compartment into the combustion chamber.
Fig. 3, is a longitudinal section and Fig. 4, an end elevation of a modified form
of vaporiser shewing the hot tube passing through the second compartment or
reservoir into the combustion chamber.
Figs. 5 and 6, are a sectional elevation and end elevation shewing a further modifi-
cation of the same with the vaporiser divided into three compartments, the hot tube
passing through the reservoir compartment as in the previous figures.
The same letters refer to similar parts throughout the several views.
a, is the combustion chamber.
b, is the vaporiser.
c, is the vaporiser reservoir or second compartiment.
d, is the third compartment of the vaporiser where the vapor is further heated
immediately before it is admitted into the combustion chamber.
e, being the valve by means of which such admission is regulated.
f, is the hot or ignition tube.
g, is the cover to the vaporiser on the removal of which the several divisions or
compartments of the vaporiser may be examined and cleaned.
h, is the motor cylinder.
i, is the water jacket surrounding the same.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
1. In oil or hydro-carbon motors, the particular arrangement and combination of
parts and appliances, comprising the combustion chamber and vaporiser fitted as
part of or an extension of the cylinder of the engine, the combustion or compression
chamber being an inner space surrounded by an annular space forming the vaporiser,
a hot or ignition tube similar to that used in gas engines having a connection
through the vaporiser into the combustion chamber, the opening of the hot tube in
the combustion chamber being placed so that the mixture is ignited where it is
hottest and richest in vapor in the manner and for the purposes substantially as
herein described and illustrated.
2. In oil or hydro-carbon motors the modification of the particular arrangement and
combination of parts and appliances described in Claim 1, by dividing the annular
space round the combustion chamber which forms the vaporiser into two or more
compartments in the manner and for the purposes substantially as herein described
and illustrated.
3. In oil or hydro-carbon motors so arranging the vaporiser compartments which
surround the combustion chamber that on removal of the cover the said compart-
ments may be examined and rendered accessible for cleaning in the manner and for
the purposes substantially as herein described and illustrated.
