PROVISIONAL SPECIFICATION.
Improvements in or Additions to Kettle and other Heating Lamps
or Lamp Stoves.
I, THOMAS HENRY THOMPSON, of 18 Spring Road Edgbaston, in the City of
Birmingham, Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in, or additions to, kettle and other
heating lainps, or lamp stoves, for the boiling or heating of vessels, supported upon
stands or rests.
My invention has for its object, the regulation of the size of the flame, hence
the regulation of heat, and this I accomplish by providing the upper extremity
of the wick casing or tube, with a supplementary tube, or short cylinder, which
when raised to its maximum height, comes above, or on a level with, the top
of the wick, which is above the wick casing carrying it, and when at its lower
position, it comes on a level with the top of the said wick casing.
When the said regulator or supplementary tube is in the first named position, the
flame is small, and is employed only for imparting only a moderate heat, but when
the regulator is down, then the flame is of a large size, and is employed for boiling
or other heating purposes.
In carrying out my invention, I provide a vessel for containing spirit or other oil,
with a depending wick tube, directed from the middle of its cap or cover, which
may be attachedly connected to the vessel by looped ears upon the one part, taking
over and upon outstanding inclines of the other part.
The centre of the lamp has a wick stem, over which the wick is placed, so that
the wick comes between the wick casing, and the peg.
Surrounding the upper part of the said wick casing, is a supplementary tube or
regulator, sliding telescopically into an outer position, and which is raised by a
branched arm or lever, actuated by a turn, jointed at its inner end to a cover or cap
of the vessel.
The movement of the turn in one direction, raises the regulator to a height above
the wick, and so partially damps off, or puts out the same.
The now movement of the turn in the reverse direction, lowers the regulator,
leaving the wick exposed for full burning.
By my invention the flame of the wick can be regulated as may be desired,
according to the position to which the regulator has been raised or lowered.
Dated this 6th day of July 1891.

COMPLETE SPECIFICATION.
Improvements in or Additions to Kettle and other Heating Lamps
or Lamp Stoves.
I, THOMAS HENRY THOMPSON of 18 Spring Road Edgbaston in the City of
Birmingham, Brass Founder, 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 additions to, kettle, and other
heating lamps, or lamp stoves used for the boiling, heating or keeping warm,

page_text: of water or liquids, contained within vessels, principally supported upon stands,
or rests.
My invention has for its object, means for regulating the size of the flame
of the said stoves, hence the augmentation or diminution of heat thereby; and
which said regulating means consists, in providing the upper extremity of the
wick casing or tube, with a supplementary tube or short cylinder, which when
raised to its maximum height, comes above, or on a level with, the top of the
wick which is above the wick casing carrying it, and when at its lower position,
it comes on a level with the top of the said wick casing.
When the said regulator or supplementary tube is in the first named position,
the flame is small, and is employed only for imparting a moderate heat, but
when the regulator is down as in the second named position then the flame is of
a larger size, and is employed for boiling or other heating purposes.
In carrying out my invention, I take an ordinary vessel, suitable for containing
spirit or oil, and I direct down the middle of the same and its cap a depending and
outside tube, which admits of being raised and lowered by a bifurcated or branched
thumb lever.
Arranged concentrically within the middle of this sliding tube, which is the wick
regulating tube, is a wick stem, over which, and between the sliding tube, the wick
of the lamp comes.
The movement of the lever turn in one direction, raises the regulator to a height
above, or about on a level with the wick and so partially damps off or regulates the
size of the flame.
The movement of the turn in the reverse direction, lowers the regulator, leaving
the wick exposed for full burning.
By my invention the flame of the wick, can be regulated as may be desired,
according to the position to which the regulator has been raised or lowered.
Figure 1 of the accompanying drawing, represents in vertical section a heating
lamp, or lamp stove, provided with a flame regulating means, made and provided
according to my invention.
The said regulator, which consists of a sliding tube or sleeve, over the outside of
the wick, is shown down, or in its lowered position, hence a large flame, augmented
by the uncovering, and leaving naked, of a large portion of the upper end of the
wick.
Figure 2 represents a like view as Figure 1, but with the flame regulator raised,
and covering up the whole or nearly the whole of the outside top of the wick, hence
a small flame, and a reduction of heat.
When the regulator is in position Figure 1, the lamp stove is employed generally
for boiling or heating, but when in the position Figure 2, the heat evolved from the
flame, keeps warm, up to a given temperature, liquid contained within a vessel.
Figure 3 is an elevation of the said stove or lamp, whilst Figure 4 is a plan of the
same.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is a vessel or spirit container, and is an open ended and fixed tube, or wick
stem, directed up the middle of the said vessel, and provided with an air shaft
wherethrough air is drawn or ascends, for feeding the interior of the flame of the
lamp, a is the cap or cover of the lamp or container having a neck flange a³, at
the middle of its crown or upper part.
c is a flame regulating tube, with a slightly expanded and open top end and
which tube slides vertically upon an interlocated wick e, directed between the inner
and fixed tube b, and outer sliding tube c, which works through the neck flange a³
of the cap.
The upper end e², of the wick, comes above the top of the tube , and above
the top c, of the sliding tube, when the last named is in its down position, as shown
at Figure 1.
The flame regulating tube is depressed and picked up by a forked arm f, of a

page_text: thumb or turn lever, fulcrummed at ³, engaging with studs c³, on the two opposite
sides of the tube c.
The said forked ends, have slots, to admit of the flame regulating tube c, being
picked up or depressed vertically, or concentric with the wick.
g is the extinguisher or lid, jointed at g², and by throwing the same over the top
of the wick the flame of the lamp is extinguished.
By turning in one direction the thumb lever f, upon its fulcrum or joint, the
tube c, is raised, which brings the mouth e, of the tube c, about on a level with the
top of the wick e, hence the damping-off or covering up of the said wick, which now
gives only a very small flame as represented in Figure 2.
The turning of the thumb lever in the reverse direction depresses the flame
regulating tube, and exposes or leaves naked a considerable portion of the said wick,
hence a large flame, as in Figure 1.
The raising or lowering of the said flame regulating tube to a greater or less
height, gives unto the lamp a greater or less fame, according to the relative
positions of top regulating tube and wick.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is
First: In a heating lamp, or lamp stove, employing in connection with the wick,
of a sliding wick regulating tube c, as set forth.
Secondly-In a heating lamp, or lamp stove, having a flame regulating tube,
the employment of a thumb lever, constructed, arranged and fitted as set forth.
Thirdly-In a heating lamp or lamp stove, the construction and arrangement of
the parts, as set forth.
