page_text: I, THOMAS WILLIAM NAYLER, of Friars Street, Hereford, in the County of
Hereford, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in vaporisers for the evaporisation of
heavy oils used for motor purposes whereby I am enabled to obtain a complete
vaporisation of the oil.
My invention consists in providing the vaporising chamber with a zig-zag
or corrugated interior sides which may form a zig-zag chamber in the direction
of the course of the spray or vapor and air, so that a maximum surface area may
be provided for radiation and for contact by the spray or vapor, and air, in
passage there-through, so that also the exterior sides of the vaporising chamber
shall correspond in configuration to that of the interior or be likewise corrugated
or zig-zag in form, so that a large extent of surface may be exposed to the flame
applied thereto for maintaining the chamber at à temperature suitable for the
vaporisation of the particles of oil injected therein.
In carrying my invention into effect as applied to an oil motor having the
usual Otto cycle of oneration, I mount the vaporiser at the back of the cylinder
with its communicating aperture in alignment with the aperture of the com-
bustion chamber or the cylinder of the engine.
I provide the vaporising chamber angularly disposed so that its zig-zag exterior
sides may be played unon and heated by a lamp provided for the purpose, and I
provide at the upper extremity of the vaporising chamber an air valve which
opens at determined intervals for the admission of air. I provide for the
injection of oil into the combustion chamber by gravity or by pumping or
spraying into the chamber at determined intervals corresponding to the cycle
of operation.
At the foot of the vaporiser I provide an ignition tube which is heated to
incandescence by a lamp for the ignition of the explosive mixture upon com-
pression. Upon the forward stroke of the piston the air is drawn and the oil
is injected into the vaporiser and on passage in a zig-zag course the air becomes
heated and particles of oil are converted into vapor and saturate the air, the vapor
becoming at the same time intimately mixed with the air. The supply of air
is cut off and upon the return stroke of the piston the mixture which has been
drawn through the vaporiser, is compressed, and ignited by the incandescent
tube, thereby producing 'an explosion and a motive impulse."
I provide my vaporiser with a casing in which the flame or flames are arranged
to play upon the igniter tube and vaporiser.
I sometimes dispense with the use of an incandescent tube in which event I

with the walls of the vaporising chamber which may be heated to a sufficient
degree for this purpose.

I, THOMAS WILLIAM NAYLER, of Friars Street, Hereford, in the County of
Hereford, Engineer, do hereby declare the nature of this invention end 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 improvements in vaporisers for the evaporisation of
heavy oils used for motor purposes whereby I am enabled to obtain a complete
vaporisation of the oil.
My invention consists in providing the vaporising chamber with a zig zag
or corrugated interior sides which may form a zig zag chamber in the direction
of the course of the spray or vapor and air, so that a maximum surface area may
be provided for radiation and for contact by the spray or vapor, and air, in
passage there-through, so that also the exterior sides of the vaporising chamber
shall correspond in configuration to that.of the interior or to be likewise corrugated
or zig zag in form, so that a large extent of surface may be exposed to the flame
applied thereto for maintaining the chamber at a temperature suitable for the
vaporisation of the particles of oil injected therein.
The accompanying drawings illustrate one mode of carrying my invention into
effect and Figure 1 is a part sectional elevation and Figure 2 a plan of the
same.
In carrying my invention into effect as applied to an oil motor having the usual
Otto cycle of operation, I mount the vaporiser A at the back of the cylinder B
with its communicating aperture C in alignment with the aperture of the
cylinder of the engine, ana in this modification the vaporiser forms a combined
vaporizer and combustion chamber.
I arrange the vaporizing or combustion chamber so that its zig zag exterior
sides D may be plaved upon and heated by a lamp such as E provided for the
purpose, and I provide at the upper extremity of the vaporisino chamber a valve
which opens at determined intervals for the admission of oil and air, this valve
being placed at F but not shown in the drawings.
I also may provide for the injection of oil into the combustion or vaporiser
chamber by gravity or by pumping or spraying into the chamber at determined
intervals corresponding to the cycle of operation.
At the foot of the vaporiser I provide an ignition tube G which is heated :.
incandescence by the lamp E for the ignition of the explosive mixture upon com-
pression. Upon the forward stroke of the piston the air and oil is drawn into
the vaporiser A striking the zig zag surfaces D becomes heated the particles of
oil are converted into vapor and saturate the air, the vapor becoming at the same
tim intimately mixed with the air. The supply of air is cut off and upon the
return stroke of the piston the mixture which has been drawn through the
vaporiser, is compressed and ignited by the incandescent tube G, thereby
producing an explosion and a motive impulse,

page_text: I provide my vaporiser with a casing H in which the flame or flames are arranged
to play upon the igniter tube and vaporiser.
I sometimes dispense with the use of an incandescent tube in which event 1
may effect the ignition of the compressed mixture of vapor and air by contact
with the walls of the vaporising chamber which may be heated to a sufficient
degree for this purpose.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In oil engine vaporisers or combustion chambers the provision of zig zag
or corrugated surfaces upon which a mixture of oil and air or oil only impinges,
as a means for rapid vaporization of the oil and heating of the air owing to the
increased heating surface presented.
2. The improvements in oil engine vaporisers or combustion chambers sah.
stantially as and for the purpose hereinbefore described with reference the
accompanying drawings.
