Improvements in Oil or Spirit Vaporizing Apparatus for Heating or
similar purposes.
I, THOMAS WATKINS, of 120, Saint Aldates Street, Oxford, Dentist, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in oil or spirit vaporizing apparatus
for heating or similar purposes, and consists broadly as follows:-
I provide an inverted bell shaped body of metal around and upon whose sides
the burning flame is to play as hereinafter described. The upper overhanging
(bell base) part serving to spread out the flame into an enlarged diameter. The
oil or material from which the gas is produced is contained in a reservoir under
pressure with which it communicates by means of a pipe leading to the lower
part of the said body. Zig-zag vertically inclined passages are now made in and
around the said body, which is preferably done in a right and left hand direction
from such inlet, until they again meet at the opposite side, where they are now
conjointly conveyed to a (central) down passage through the body and to a
suitable distance below it, where it is again divided and passes in opposite direc-
tions, and again upwards towards and near the bottom of the body, and terminates
each with a pin-hole burner or burners. In the downward passage and below the
body is placed a regulating tap or valve. At a suitable distance below the burners
is an internal cleaning wire or pin, which is capable of a sliding to and fro
motion, so that it may be passed from time to time as desired, through the burner
to remove dirt or other obstruction therefrom. This sliding motion may be
effected in manner varying in detail but preferably to do this I provide a stuffing
box and gland through which a part rotative spindle passes having a suitable
handle &c. for operating same. At the inner end of this spindle is a crank device
connection with the slide aforesaid, so that by part rotating the said spindle the
cleaning may be effected when desired. Encircling the burners I now provide an
annular Bunsen air chamber by which air may enter below and mix with the gas
in its consumption. Usually two of such air chambers are used, opposite to each
other, and each encircling the body about one third of its circumference, more or
less. In some cases however I may unite them into one common chamber, or in
some cases instead of adhering to the circular form of body I may vary it as
triangular, or rectangular for instance, and in such case I similarly arrange the
flame to play upon the sides.
In use, the commencement of working is effected by first heating the body by
an ordinary gas flame or other convenient means, until sufficient gas has been
vaporized to supply the burners described, when the heat therefrom will continue
the operations.

I, THOMAS WATKINS, of 120, Saint Aldates Street, Oxford, Dentist, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in oil or spirit vaporizing apparatus
for heating or similar purposes, and consists broadly as follows:
In order to more clearly explain this my invention I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference in
which:-
Fig. 1 is a vertical elevation of an apparatus embracing this my invention.
Fig. 2 is a plan of the apparatus.
Fig. 3 is a front end view of the apparatus.
Fig. 4 is a vertical sectional view of the hell shaped generating chamber, on
line A B (Fig. 2).
Fig. 5 is a vertical sectional view of the generating chamber on line C-D
(Figs. 2 & 4).
Fig. 6 is an enlarged vertical sectional view of the burner and its combined
cleaning needle and valve, on line E-F (Fig. 1).
I provide an inverted bell shaped body S, of metal, around and upon whose
sides the burning flame 9 is to play as hereinafter described. This body serves as
the vapourizing or gas generating chamber. The upper overhanging (bell base)
projecting part 10, serves to spread out and reflect the flame, thus increasing its
diameter. The oil (or material) from which the gas is produced is contained in
a reservoir (under pressure) (not shown), with which communication is made by
means of a pipe 11, leading to the lower part of the said body. Zig-zag vertically
inclined passages 12, 12, are now made in and around the said body 8, which is
preferably done in a right and left hand direction from such inlet 11, see Fig. 5,
until they again meet at the opposite side at 12, where they are conjointly con-
veyed to a central down passage 13, through the body and to a suitable distance
below it, where it is again divided and passes in opposite directions by pipes 14, 14,
and again upwards towards the bottom of the body S, and terminates each with a
pin-hole burner or burners 15. In the downward passages and below the body is
placed a regulating tap or valve 16, by which the quantity of generated gas may
be controlled in its supply to the burners. At 17, is a wire gauze or other suitable
substance through which the gas has to pass and which collects carbon, dust, or
other impurities, thus preventing to that extent their interference with the
burners. This filtering substance may be readily inserted or removed for
cleaning &c. by means of taking out the screw plug 18. Part of the structure in
Fig. 1, is shown broken and removed in order to illustrate this device.
At a suitable distance below the orifice of the burners is an internal cleaning
wire or pin 19, which is capable of a sliding to and fro motion, so that it may be
passed from time to time as desired, through the burner to remove dirt or other
obstruction therefrom (see Fig. 6). The point of this needle is cone shaped or
rounded so that it may be also used as a regulating valve whereby the flames from
the two (or more) burners may be balanced. This double use of the device is
most advantageous inasmuch as frequently the flame from one burner exceeds that
of the other and thus tends to pull the heat disadvantageously to one side;
but by the means described they may be readily kept in balance. The necessary

page_text: sliding motion for the pin 19, may be effected in manner varying in detail but
preferably to do this I provide a stuffing box 20, and gland 21, through which a
part rotative spindle 22 passes, having a suitable handle 23 &c. for operating same.
At the inner end of this spindle is a crank pin 24, secured in the spindle 22, and
engaging in a slot in the slide 19 aforesaid, so that by part rotating the said spindle
the cleaning may be effected when desired. As seen in Fig. 6, the slide is at half
stroke, but when turned completely down the burner orifice is free for the passage of
the gas. Encircling the burners I now provide annular Bunsen air or mixing
chambers 25, by which air may enter below and mix with gas in its consumption,
resulting in the flame 9, at their upper ends. In these mixing chambers I cut
away the lower corners so as to provide the inclined air openings at the sides.
Usually two of such air chambers are used, opposite to each other, and each
encircling the body 8, about one third of its circumference, more or less. In some
cases however I may unite them into one common chamber, or in some cases
instead of adhering to the circular form of body I may vary it as triangular, or
rectangular for instance, and in such cases I similarly arrange the flame to play
upon the sides.
In use, the commencement of working is effected by first heating the body 8,
by an ordinary gas flame or other convenient means, until sufficient gas has been
vapourized to supply the burners 15, when the heat therefrom will continue the
operations. Any desirable regulating valve may be used in or connected with the
pipe 11, for controlling the supply of oil &c.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In vapourizing apparatus the solid metallic body 8, having the zig-zag
passages 12, with inlet 11, and central outlet 13, substantially as shown and
described.
2. In vapourizing apparatus the combination with suitable supply means for
the introduction of a liquid hydrocarbon, and of outlet 13, burners 15, and mixing
chambers 25 of the vapourizing body S, having zig-zag passages 12, all substan-
tially as set forth and shown.
3. In vapourizing apparatus the interposing between the vapourizing chamber
and the burners, of the filtrating device 17, substantially as set forth and shown.
4. In vapourizing apparatus the combination with the burner 15, of the sliding
pin 19, arranged and adapted to serve for cleaning burner and also controlling
supply substantially as set forth and shown.
5. In vapourizing apparatus the employment and use of the reflecting projec-
tion 10, upon the generating body 8, substantially as set forth and shown.
