Improvements in and connected with Oil or Vapour Burners for
Heating Purposes, Brazing, and Melting Metals, and the like.
I, THOMAS WATKINS, of 120 St. Aldates Street, Oxford, Dentist, do hereby
declare the nature of this invention to be as follows:-
My invention relates to certain improvements in oil or vapour burners and it
consists in a simple construction of same adapted for heating purposes as well as
its arrangement with a heating melting or brazing furnace whereby small
quantities of metal such as zinc lead and the like can be melted or articles razed.
My improved apparatus consists of a suitable oil tank provided with the
necessary cocks and gauge and an air pump for putting pressure upon the oil.
A pipe from the tank which may be flexible or not as desired leads to the burner
portion which consists of a valve preferably having a conical ended adjustable
spindle seating in a correspondingly shaped recess to close and open a passage
for the oil, the size of the passage being regulated by the position of the spindle.
To keep the passage clear a needle passes through the spindle and enters the
passage such needle being preferably controlled by a spring. The needle is
connected to a spindle which may be provided with a suitable handle so that the
needle may be worked up and down in the passage. The nozzle of the valve above
described, is situated at a short distance at the rear of a coil of pipe which is
connected to or forms part of the pipe leading the oil to said nozzle. Over the
coil but so arranged that the nozzle and valve is exposed is placed an open ended
sheet iron or other suitable case preferably conical in form having at one end
an asbestos ring or the like the edge of which forms a baffle to the vapour radiating
from the nozzle so that the stream is checked and thrown back on the coil and
against the case. The vapour is ignited at the asbestos ring and the case and the
coil become sufficiently heated to vapourize the oil passing through the centre of
the coil.
The flame regulates itself in a measure automatically as while the pressure is
great the flame is driven forward and the coil receives less neat while with a lower
pressure the flame comes back towards the coil and more highly vaporize the oil.
The amount of air passing into the case from the nozzle end may be regulated
by a suitable cover or door.
To start the burner a small flame is ignited at the nozzle so as to heat the coil
which may be also previously heated by burning oil spirit or the like around it.
For melting metals or for brazing, the nozzle may be provided with a small
round hole while for heating purposes such as heating boilers a flat thin slot may
be used.
The burner or it may be more than one burner may be arranged to project

page_text: through the sides or top of a furnace casing so as to project the flame upon the
hearth or bed of same or it may be a ladle supported thereon.

Improvements in and connected with Oil or Vapour Burners for
Heating Purposes, Brazing and Melting Metals, and the like.
I, THOMAS WATKINS, of 120 St. Aldates Street, Oxford, Dentist, 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 certain improvements in oil or vapour burners and
consists in a simple construction of same adapted for heating purposes as well as
its arrangement with a heating melting or brazing. furnace whereby small
quantities of metal such as zinc, lead, and the like can be melted or articles
brazed,
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part, and in
which: :-
Fig. 1, is a side elevation of this my improved oil or vapour burner.
Fig. 2, is a plan view of the invention.
Fig. 3, is a side sectional elevation showing also 'the relative position of the
burner with the heating, melting or brazing furnace.
My improved apparatus consists of any ordinary suitable oil tank provided with
the necessary cocks and gauge and an air pump for putting pressure upon the oil.
This tank &c is not shown as it forms no part of my invention. A pipe 5, from
the tank which may be flexible or not as desired, leads to the burner portion which
consists of a valve 6, preferably having a conical ended adjustable spindle 7,
seating in a correspondingly shaped recess 8, to close and open a passage for the
oil, the size of the passage being regulated by the position of the spindle, which
is operated by the handle 9.
To keep the passage 10, clear, a needle 11, passes through the spindle 7, and
is made to enter the passage at will by pressure upon the knob 12, such needle
being preferably controlled by a spring 13, so that the needle may be worked up
and down in the passage. The nozzle 14, of the valve above described is situated at a
short distance above the coil 15 which is connected to or forms part of the pipe 5,
leading the oil to said nozzle. Over the coil, but so arranged that the nozzle and
valve is exposed, is placed an open ended sheet iron or other. suitable case 16,
having at one end an asbestos ring 17, or the like, the edge of which forms a baffle
to the vapour (indicated by dotted lines 18) radiating from the nozzle, so that the
stream is checked and thrown back on, the coil and against the case as indicated
at 19. The vapour being ignited at the asbestos ring, the case and coil thus
become sufficiently heated to vapourize the oil passing through the centre of the
coil.
The flame regulates itself in a measure automatically as while the pressure is
great the flame is driven forward more directly through the nozzle 20, and the

page_text: coil receives less heat, while with a lower pressure more of the flame strikes the
ring 17, and comes back towards the coil and more highly vapourize the oil.
The amount of air passing into the case from the nozzle and may be regulated
by a suitable sliding &c cover or door 21, or in addition thereto air holes 22, may
be used.
To start the burner a small flame is ignited at the nozzle 14, so as to heat the
coil 15, which may be also if desirable previously heated by burning oil spirit or
the like around it.
For melting metals or for brazing, the nozzle 14, may be provided with a small
round hole while for heating purposes such as heating boilers a flat thin slot may
be used.
The burner or it may be more than one burner-may be arranged to project
through the sides or top of a furnace casing such as 23, (see Fig. 3) so as to project
the flame upon the hearth or bed of same or it may be a ladle supported thereon.
The form of furnace or ladle &c will necessarily vary according to its specific use.
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.
In oil or vapour burners such as those herein described the combination con-
sisting of the pipe 5, coil 15, having the valve 6, spindle 7, with needle device,
and the casing 16, having nozzle 20, all constructed and operating substantially
as set forth and shown.
