Improvements in Oil Stoves or in Apparatus Connected therewith.
We, FREDERICK TYERS and WALTER SHEPHARD, both of 247 Mansfield Road,
Carrington, in the Borough of Nottingham, Plumbers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to stoves which are heated by the combustion of oil and
it has for its object the improved construction and arrangement of such stoves, or
apparatus connected therewith.
In carrying out this invention the base of the stove or apparatus is formed by
a vessel af suitable size and shape in which is contained the oil, a suitable opening
being formed, fitted with a preferably screw cap for filling; arranged over this
vessel is an open framing supported on pillars or other convenient supports, on which
a vessel containing liquid to be heated, or metals to be melted may be placed. On
the underside of this framing is secured a preferably cylindrical casing having holes
formed in the sides to admit air; inside this casing is a helix formed of tubing
the upper end of which is connected by a supply pipe with the vessel.
It may
pass through the top of the vessel containing the oil, to which it is secured, and
extend to the bottom, or it may pass down to the base of the vessel on the outside
and there be secured. This supply pipe is provided with a suitable stop-cock which
may be placed near the centre and the space above and below filled with any suitable
material which will allow the oil to percolate or gradually pass through.
The lower end of the tubular helix is fitted with a suitable pipe or burner. The
oil may be forced up the supply pipe by compressing the air contained in the vessel
over the oil, and is effected by forcing air through an opening in the top fitted with
a stop-cock to which a pipe is connected; sufficient pressure may be obtained to keep
the stove burning some time by blowing in with the mouth, or if preferred the pipe
may be fitted with an india-rubber air ball and the air forced in by compression of
the ball.
The oil is lighted at the burner and the flame passing up the centre heats the
helix thus rapidly turning the oil as it is gradually supplied into vapour which burns
fiercely.
When melting metal in a crucible or metal pan we preferably arrange an outer
casing round the crucible or pan so as to confine the heat."
The foregoing arrangement is specially adapted for melting metal, heating liquids,
soldering irons, and for general plumbing purposes, for which a portable stove is
necessary but it inay be modified to suit different requirements.

COMPLETE SPECIFICATION.
Improvements in Oil Stoves or in. Apparatus Connected therewith.
We FREDERICK TYERS and WALTER SHEPHARD both of 247 Mansfield Road,
Carrington, in the Borough of Nottingham, Plumbers, 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 stoves which are heated by the combustion of oil and it
has for its object the improved construction and arrangement of such stoves or
apparatus connected therewith.
It will be best understood by reference. to. the accompanying drawings in. which

page_text: Fig. 1 is a vertical section and Fig. 2 a plan of a portable stove or furnace adapted
for heating liquids or melting metal.
In carrying out this invention the base of the stove or apparatus is formed by a
plate or ring A to which is secured a vessel B of a suitable size and shape in which
is contained the oil, a suitable opening being formed fitted with a preferably screw 5
cap C for filling.
Arranged preferably over this vessel is an open framing D supported on pillars E
the lower ends of which are secured to the base plate or ring A, the framing D is
provided with projections D' on which a vessel containing liquid to be heated, or
metal to be melted may be placed. On the underside of the framing D is secured a
coil of tubing F formed with an open space in the centre, and connected hy its upper
end to the vessel or oil reservoir B by a supply pipe G extending to near the bottom
of the vessel and provided with a stopcock or valve H for regulating the supply of
oil to the coil, the lower end of the coil is turned downwards and is fitted with a
short tube I passing under the coil one or more holes J. being formed in it at that
part corresponding to the centre of the coil.
The coil F is preferably surrounded by a perforated casing K which is secured by.
its upper edge to the framing D and is preferably provided with a concave bottom t
catch any overflow of oil, it may also be provided with an opening fitted with a
door so as to give access to the coil for lighting.
The oil is preferably forced up the supply pipe by compressing the air contained
in the vessel or oil reservoir B over the oil, this may be effected by forcing air
through an opening in the top fitted with a stopcock to which a pipe is connected,
sufficient pressure may be obtained to keep the stove burning sometime by blowing
in with the mouth, or if preferred the pipe may be fitted with an india-rubber air
ball and the air forced in by compressing the ball; in large apparatus however we
preferably attach a cylindrical air pump L provided with a piston M which may be
operated by hand this may be secured by passing it through the vessel B as shown
in the drawings, a vertical pipe N being connected to convey the air above the oil,
the piston rod O at one side of the vessel may be fitted with a cross head or handle O'
and the end of the pump at the other side of the vessel may be fitted with a remove-
ablo cap P so as to give access to the valve.
When the oil is lighted at the burner the flame passes up the centre of the tubular
coil which it heats, thus rapidly turning the oil into vapour as it is gradually supplied,
which burns fiercely and causes a blast as it escapes from the coil at a great pressure.
When melting metal in a crucible or metal pan we preferably arrange an outer
casing round the crucible or pan so as to confine the heat, this casing may be pro-
vided with an opening fitted with a door so that soldering irons or other articles may
be inserted and heated. The foregoing arrangement is specially adapted for melting
metals beating liquids or soldering irons, and for general plumbing purposes for which
a portable stove is necessary but it may be modified to suit other requirements.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In an oil stove the combination and arrangement of a coil such as F with a tube
or burner such as I, J, substantially as and for the purpose described and illustrated in
the accompanying drawings.
2. In an oil stove the combination with a coil F and tube or burner I, J, of a
framing such as D, D', for supporting a vessel or the like substantially as described
and illustrated in the accompanying drawings.
3. In an oil stove the combination with a coil F burner I, J. framing D, D₁ of a
vessel such as B to contain oil and compressed air substantially as described and
illustrated in the accompanying drawings.
4. In an oil stove the combination with the oil reservoir of a pump or equivalent
means for compressing the air in such vessel substantially as herein described and
illustrated in the accompanying drawings.

page_text: 5. The combination and arrangement of parts forming the complete oil stove con-
sisting essentially of a coil F, burner I, J, framing D, D', supply tube G, provided
with a stopcock or valve, vessel B for containing oil, and air, pump L, substantially as
described and illustrated in the accompanying drawings.
