Improvements in Oil Vapor Stoves for Burning Off Paint or for like
Purposes.
F, FREDERICK TYERS, of 47A, Waldeck Road, Carrington, in the City of Not-
tingham, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to improvements in oil vapor stoves for burning off
paint, or for like purposes, and it has for its object, to provide a stove that will
burn what is ordinarily known as paraffin oil, and in which the length of the
flame, and the consequent heat, may be readily regulated to suit the particular
purpose to which it is to be applied.
According to my invention, the vaporizing coil and vapor jet, are contained
in a preferably outer cylindrical casing, (hereinafter termed the burner casing)
provided at one end with a nozzle having an opening of reduced diameter, and
at the other with an approximately semi-circular end plate which partially
closes this end. The burner casing at this end is also provided with suitably
shaped openings, to admit air to the interior of the casing.
The vaporizing coil which is preferably formed of a tube coiled into an annular
form, is placed in or near the nozzle of the casing, concentric with the opening
in the latter.
A continuation of the coil is carried down the interior of the cylindrical casing,
and is connected to a jet casing, which is preferably secured to the semi-circular
end of the burner casing.
This jet casing is provided with a jet or nipple having an aperture of suitable
size, arranged to deliver the oil vapor generated in the coil, through the interior
of the said coil, at which point it ignites, and the flame is forced through the
nozzle of the burner casing.
The jet casing is also provided with a preferably screw down valve, which is
preferably conical, and which screws down preferably on to a seat formed by
the inner end of the jet or nipple, and thus regulates the escape of the vapor
from the latter.
The jet or nipple is preferably made independently of the jet casing, and is
preferably screwed therein.
The stem of the valve is carried through a stuffing box in the jet casing, and
through the end of the burned casing, and is provided with a wheel or other
suitable device, preferably formed of a material which is a non-conductor of
heat, by means of which the valve is regulated.
The burned casing is placed in a preferably inclined position above the oil
reservoir, the nozzle end being the highest. The lower end is connected to a
bracket secured to the top of the reservoir, whilst the nozzle end is supported
on a stay, which is carried from the said nozzle, down to an extension of the
base of the reservoir.
This stay is formed angular in section, and with sharp edges, in order that
the operator may use it for removing burnt paint from his tool or scraper. This

page_text: process is facilitated by reason of the fact, that the stay owing to its position,
becomes heated when the stove is in use.
The lower end of the burner being partially closed by an end plate as previously
described, a receptacle is formed, in which a little oil may be placed and ignited,
for the purpose of heating the coil, and thus starting the stove.
The oil container or reservoir which may be of any convenient shape, is pro-
vided with a handle, the upper end of which may be connected to the same
bracket as the lower end of the burner casing, and its lower end to an extension
of the base of the reservoir.
The vaporizing coil is connected to the reservoir by a pipe which is preferably
a continuation of the said coil, this pipe is screwed into a cap or gland which is
in turn screwed into a seating in the top of the reservoir. This cap is connected
to a pipe which is carried to the bottom of the reservoir, from which the oil
supply is thus taken.
The reservoir is also provided with an inlet for filling, the screw cap of which
is provided with an air outlet, preferably of the screw down type, and also with
a pump to compress air over the oil. The main part of the pump is preferably
placed within the reservoir but the non-return valve is placed in a chamber of
less diameter, set at an angle to the main part, and the end carried to the out-
side of the top of the reservoir, where it is fitted with a screw cap so that the
valve can be inspected at any time without difficulty.
The valve is formed of metal and is preferably conical, it is placed in an
approximately vertical position in the chamber described, and works by its
own weight assisted by a spring if desirable.
Its position owing to this arrangement, is above the level of the oil and the
latter cannot therefore escape into the pump, and interfere, with or injure the
latter.
By enclosing the vaporizing coil and jet in a casing such as described, a
steady flame is obtained, and by placing the valve near the jet or nipple, the
stove is controller by regulating the exit of the vapor from the coil, instead of
the admission of oil to the latter. A better balance is thus obtained between
the air pressure in the reservoir and the vapor pressure in the coil, and the
length of flame may be thus adjusted, and it will burn steadily with either a
large or small flame.

Improvements in Oil Vapor Stoves for Burning Off Paint or for like
Purposes.
I, FREDERICK TYERS, of 47A, Waldeck Road, C'arrington, in the City of Not-
tingham, 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 oil vapor stoves for burning off
paint, or for like purposes, and it has for its object, to provide a stove that will
burn what is ordinarily known as paraffin oil, and in which the length of the
flame, and the consequent heat, may be readily regulated to suit the particular
purpose to which it is to be applied.

page_text: The invention will be best understood by reference to the accompanying draw-
ings in which
Fig. 1 is an elevation partly in section of an oil stove constructed according
to my invention.
Fig. 2 is a sectional view of part of the air pump. Like letters indicate like
parts throughout the drawings.
According to my invention, the vaporizing coil A (see Fig. 1) and vapor jet
casing B, are contained in a preferably outer cylindrical casing C, (hereinafter
termed the burner-casing) which is provided at one end with a nozzle Chaving an
opening of reduced diameter, and at the other with an approximately semi-circular
end plate CB which partially closes this end. The burner-casing C is at this end
also provided with suitably shaped openings C, to admit air to the interior of
the casing.
The vaporizing coil A which is preferably formed of a tube coiled into an
annular form, is placed in or near the nozzle C" of the casing C, and concentric
with the opening in the latter.
A continuation A' of the coil is carried down the interior of the cylindrical
casing C, and is connected to the jet-casing B, which latter is preferably secured
to the semi-circular end (2 of the burner-casing.
This jet-casing is provided with a jet or nipple B₁ having an aperture of
suitable size, arranged to deliver the oil vapor generated in the coil A, through
the interior of the said coil, at which point it ignites, and the flame is forced
through the nozzle C of the burner-casing
The jet-casing is provided with a preferably screw down valve D, which is
preferably conical, and which screws down preferably on to a seat 12 formed
on the inner end of the jet or nipple 31 and thus regulates the escape of the
vapor from the latter. The end of the valve D is provided with a reduced part 1)*
which extends beyond the seat 132, and enters the small aperture in the nipple 131
when the valve is secured down and acts as a cleaner.
The jet or nipple B is preferably made independently of the jet casing B,
and is preferably screwed therein.
The stem of the valve D) is carried through a stuffing box B on the jet
casing B and is provided with a wheel or other suitable device D³, preferably
formed of a material which is a non-conductor of heat, by means of which the
valve stem is rotated.
The burner casing C is placed in a preferably inclined position above the oil
reservoir with the nozzle C the highest. Its lower end is connected to a bracket E
secured to the top of the reservoir F, whilst the nozzle end C is supported on
a stay C, which is carried from the said nozzle, down to the base of the reser-
voir.
The stay G is formed angular in section and with sharp edges, in order that
the operator may use it for removing burnt paint from his tools or scraper.
This process is facilitated by reason of the fact, that the stay owing to its position,
beconies heated when the stove is in use.
If preferred the upper end of the stay C. may be formed with a bracket or
lug C provided with a pin or stud G2, on which latter the inner end of a detach-
able rest H may be placed as shown.
This rest H may be used for supporting any article it is desired to heat.
The lower end of the burner-casing C being partially closed by the end plate C²
as previously described, a receptacle is formed in which a little oil may be
placed and ignited, for the purpose of heating the coil, and thus starting the
stove.
The oil container or reservoir F which may be of any convenient shape, is
provided with a handle I, the upper end of which may be connected to the same
bracket E as the lower end of the burner casing, and its lower end to an exten-
sion of the base of the reservoir F.
The vaporizing coil A is connected to the reservoir by a pipe 12 which is pre-

page_text: ferably a continuation of the said coil, this pipe is screwed into a gland A³
which is in turn screwed into a seating in the top of the reservoir. This gland A³
is connected to a pipe which is carried to the bottom of the reservoir, from which
the oil supply is thus taken.
The reservoir is also provided with an inlet for filling, the screw cap of
which is provided with an air outlet J', preferably of the screw down type, and
also with an air pump K to compress air over the oil. The main part of the
pump K is preferably placed within the reservoir F, but the non-return valve L
(see Fig. 2) is placed in a chamber L', set at an angle to the main part K, the
upper end of which chamber L' extends to the outside of the top of the reservoir,
where it is fitted with a screw cap L2, so that the valve can be inspected at any
time without difficulty.
The valve E is formed of metal and is preferably conical, it is placed in an
approximately vertical position in the chamber L' as shown, and works by its
own weight assisted by a spring L³ if desirable.
The position of the air outlet L is owing to this arrangement above the level
of the oil, and it cannot therefore leak into the pump, and thus interfere with
the working of or injure the latter.
By enclosing the vaporizing coil jet in a casing such as described, a steady
flame is obtained, and by placing the valve near the jet or nipple, the stove
is controlled by regulating the exit of the vapor from the coil instead of the
admission of oil to the latter. A better balance is thus obtained between the
air pressure in the reservoir and the vapor pressure in the coil, and the length
of flame may be thus adjusted, and it will burn steadily with a large or small
flame.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In an oil vapor stove the combination with a vaporizing coil such as A
of a jet-casing such as B a jet such as B¹ a valve D) and a valve seat B² sub-
stantially as described.
2. In an oil vapor stove the combination with a vaporizing coil such as A
of a jet-casing such as B, a jet B¹ a valve D a valve seat B and an extension D³
of the valve to act as a jet cleaner substantially as described.
3. In an oil vapor stove the combination with the oil reservoir F of a vaporizing
coil such as A a burner casing such as C and a stay such as G substantially
as described.
4. In an oil vapor stove the combination with the oil reservoir F of a vaporiz.
ing coil such as A a burner casing such as C a stay such as G and a rest such
as H substantially as described.
5. In an oil vapor stove the combination with the oil reservoir F of a pump K
provided with a valve chamber L set at an angle to the body K and having its
upper capped end above the top of the reservoir substantially as described.
6. The combination and arrangement of parts constituting the complete oil
vapor stove substantially as described and illustrated in the accompanying
drawings.
