PROVISIONAL SPECIFICATION.
Improvements in or connected with Apparatus for Vaporizing Oil.
I, CORNELIUS CRASTIN, of 16, Tollington Road, Holloway, in the County of
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or connected with apparatus for
vaporizing oil and mixing it with air to form an explosive mixture for driving
motors and for other purposes, the object of my invention being to prevent as
far as possible any surplus oil entering or remaining in the vaporizing chamber
when the motor or other apparatus to which the vaporizer is connected is at work
and also to prevent any oil entering the said chamber when the motor is not at
work.
To this end I provide means whereby any excess of oil is conveyed into a
receptacle in which it is stored.
In carrying out my invention I provide a chamber preferably cylindrical and
fixed in a vertical or slightly inclined position the said chamber being advan-
tageously formed of lengths of tube placed one within the other so as to leave a
space between them.
The upper and lower ends of this space are closed by
suitably shaped rings. At the bottom of the outer tube preferably at one side of
the same and on a level with the lowest point of said space I attach one end of
an inlet tube the other end of which is connected to a T piece or the like
provided with a sight feed device for supplying oil and air.
At the ton of the outer tube, and preferably on the side of the same opposite to
the inlet tube, I arrange an outlet tube leading to the motor or other apparatus
which tube may be provided with an air inlet opening controlled by a hand valve
to further dilute the explosive charge with air if necessary.
The vaporizing chamber is fitted in a suitable casing lined with a non-
conducting material and a lamp is provided so arranged that the flame or a portion
of the flame passes up into the central tube and heats the said chamber.
A tube passes from the bottom of the tee piece or the like on the inlet pipe to a
receptacle for storing any oil that is not drawn into the vaporizing chamber and
converted into gas. This receptacle is provided at the bottom with a cock to
enable the oil to be drawn off and used again.
In connection with the sight feed device I arrange a device for regulating the
air supply and the sight feed device for the oil is arranged so as to allow sufficient
oil to drop upon a small disc or piece of gauze and be carried into the vapourizing
chamber by the current of air set up by the operation of the motor.
When the motor is not at work or is running slowly any excess of oil will
find its way into the receptacle until the main supply is shut off.
The air supply may be warmed by causing it to pass through tubes in or around
the vaporizing chamber.
My improvements when applied to a motor may be arranged in conjunction
with an ignition tube casing. It will be obvious that with this construction of

page_text: apparatus the discharge from the exhaust is rendered clean and a better propor-
tioned explosive mixture is obtained than heretofore. My arrangement also
reduces the proportion of unburnt gases in the exhaust and effects a saving of oil.

I, CORNELIUS CRASTIN, of 16, Tollington Road, Holloway, in the County of
London, Engineer, 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:-
This invention relates to improvements in or connected with apparatus for
vaporizing oil and mixing it with air to form an explosive mixture for driving
motors and for other purposes for instance for heating purposes, the object of my
invention being to prevent as far as possible any surplus oil entering or remaining
in the vaporizing chamber when the motor or other apparatus to which the
vaporizer is connected is at work and also to prevent any oil entering the said
chamber when the motor is not at work.
To this end I provide means whereby any excess of oil is conveyed into a
receptacle in which it is stored.
In carrying out my invention I provide a chamber preferably cylindrical and
fixed in a vertical or slightly inclined position the said chamber being advan-
tageously formed of lengths of tube placed one within the other so as to leave a
space between them. The upper and lower ends of this space are closed by
suitably shaped rings. At the bottom of the outer tube, preferably at one side of
the same and on a level with the lowest point of the said space, I attach one end of
an inlet tube the other end of which is connected to a T-piece or junction piece
provided with a sight feed device for supplying oil and air."
At the top of the outer tube, and preferably on the side of the same opposite to
the inlet tube, I arrange an outlet tube leading to the motor or other apparatus
which tube may be provided with an air inlet opening controlled by a hand valve
to further dilute the explosive charge with air if necessary.
The vaporising chamber is fitted in a suitable casing lined with a non-
conducting material and a lam is provided so arranged that the flame or a portion
of the flame passes up into the central tube and heats the said chamber.
A tube passes from the bottom of the junction piece on the inlet pipe to a
receptacle for storing any oil that is not drawn into the vaporizing chamber and
converted into gas. This receptacle is provided at the bottom with a cock to
enable the oil to be drawn off and used again.
In connection with the sight feed device I arrange a device for regulating the
air supply and the sight feed device for the oil is arranged so as to allow sufficient
oil to drop upon a small disc or piece of gauze and be carried into the vaporising
chamber by the current of air set up by the operation of the motor.
When the motor is not at work or is running slowly any excess of oil will
find its way into the receptacle until the main supply is shut off.
In the accompanying drawing:-
Figure 1 is a sectional elevation of apparatus for vaporizing oil constructed
according to my invention;

page_text: Figure 2 is a section on the line 2-2 Figure 1; and,
Figure 3 is a section on the line 3-3 Figure 1.
a is the cylindrical vaporizer fixed in a vertical (or slightly inclined) position
and b and c are the two lengths of tubing forming the said vaporizer, the tube b
being placed inside the tube c so as to leave a space or chamber d between the
two tubes. e is the ring or plug closing the upper end of the space and is
the similar ring or plug closing the lower end thereof. g is the inlet tube one
end of which is fitted to the lower end of the tube c, the said inlet tube g Deing so
fitted that it is on a level with the lowest point of the space d between the two
tubes b and c; h is the junction piece into which the other end of the inlet tube
opens.
i is the outlet tube leading to the motor or other apparatus to which the explosive
charge is to be supplied, the said tube opening from the upper end of the tube
and eterably on the opposite side thereof to the inlet tube g.
is the inlet
opening into the said outlet pipe i and kis the hand valve with which the said
inlet is provided for enabling the explosive charge to be further diluted with air
if necessary.
Z is the casing which is lined with a suitable non-conducting material and which
surrounds the vaporizing chamber, and m is the lamp of ordinary construction
which is fitted to the casing 7 below the chamber so that the flame or a portion
thereof passes up the central space in the tube b and heats the vaporizing
chamber d.
n is the sight feed device screwed to the upper end of the junction piece h and
the oil inlet tube n° of which is formed of glass tubing drawn to a fine point.
The said device is provided at its lower end with a number of air inlet holes,n', u'
which can be partially or wholly closed by means of a ring o sliding upon the
outside of the feed device n and provided with holes o¹ corresponding in number
and size to the holes n'.
P
is a perforated disc or disc of gauze which covers the mouth of the junction
piece h, as clearly shewn in Figure 1 and q is a small funnel of sheet metal fitted
in the said junction piece to direct the surplus oil to the centre of the junction
piece h. is the tube passing from the bottom of the junction piece h and s is
the receptacle for storing the surplus oil and into which the said tuber opens. t
is the cock provided on the bottom of the receptacles by means of which the latter
can be emptied when required.
The operation of my apparatus is as follows:-The motor or other apparatus
exercises a suction effect in the inlet pipe i thereby drawing the oil, which drops
down through the sight feed device n on to the perforated or gauze disc p which
partially pulverizes it, together with air, which enters through the holes o, o' in
the said feed device, into the space or chamber d between the two tubes b and c.
This chamber is heated by the flame from the lamp m as above described and
vaporizes the oil and the gaseous mixture is then drawn through the tube i to
the motor or other apparatus where it is exploded in the usual manner. When
the motor is running slowly or is not at work, the oil which drops through the feed
device then flows in the first case partly and in the latter case wholly through the
pipe into the receptacles, where it is stored up for future use, until the main
supply is partially or wholly turned off to suit the demand. It will thus be seen
that only the requisite quantity of oil is drawn into the vaporizer, the rest escaping
into the recentacle s.
The air supply may be warmed by causing it to pass through tubes in or around
the vaporizing chamber and my improvements when applied to a motor may be
arranged in conjunction with an ignition tube casing.
It will be obvious that with my construction of apparatus the discharge from
the exhaust is rendered clean and a etter proportioned explosive mixture is
obtained than heretofore. My arrangement also reduces the proportion of
unburnt gases in the exhaust and effects a saving in oil.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. Apparatus for vaporizing oil having a junction piece interposed between the
vaporizing chamber and the oil and air feed device substantally as, and for the
purpose, hereinbefore described.
2. Apparatus for vaporizing oil comprising a vaporizing chamber formed of two
concentrically arranged tubes surrounded by a suitable casing containing non-
conducting material, and in communication at one end with the motor or other
apparatus to be supplied with the explosive charge and at the other end with a
feed device and with a receptacle for storing surplus oil, substantially as, and for
the purpose, herein before described.
3. In apparatus for vaporizing oil of the kind described in Claim 1 the employ-
ment of a perforated or gauze disc immediately below the air inlet and so arranged
that the oil from the feed device drops on to it substantially as and for the purpose,
herein before described and as illustrated.
4. The combination and arrangement of parts forming the improved. apparatus
for vaporizing oil, herein before described and illustrated in the accompanying
drawing.
