IMPROVEMENTS: IN PORTABLE STOVES
Year: 1868

page_text: „LETTERS PATENT to James Hinks and Joseph Hinks, both of
Birmingham, in the County of Warwick, Manufacturers, for the
Invention of "IMPROVEMENTS: IN PORTABLE STOVES."
Sealed the 4th August 1868, and dated the 18th February 1868.
PROVISIONAL SPECIFICATION left by the said James Hinks and
Joseph Hinks at the Office of the Commissioners of Patents, with
their Petition, on the 18th February 1868.
We, JAMES HINKS and JOSEPH HINKS, both of Birmingham, in
the County of Warwick, Manufacturers, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN PORTABLE STOVES," to be as
follows:-
Our Invention consists in combining or arranging the parts of a
portable stove in the manner herein-after described. Stoves made
according to our Invention are especially suitable for burning
petroleum oil or petroleum spirit, but other liquid combustibles may be
employed.
We construct a portable stove according to our Invention in the
following manner:-The body of the stove consists of a hollow perforated

page_text: cylinder of metal, the bottom of which has an opening sufficiently
large to permit of the cone of the burner of the lamp being passed
through it. The said body is supported above the lamp at the required
distance by means of arms or brackets on the lamp. The lamp is
supported on a stand provided with handles by means of which the
stove may be carried about. A short distance above the flame is a
hollow cone of sheet metal, up which the current of heated air and
products of combustion from the lamp pass, and on the top of the
perforated cylinder a hot water reservoir or boiler fits. The hot water
reservoir has a conical tube passing through it, up which the current
of hot air from the lamp rises and passes into the room. The cover
of the hot water reservoir and conical tube is so formed that the
heated air in passing into the room carries with it a portion of steam
rising from the water, and thus keeps the air of the room sufficiently
supplied with moisture. By means of a tap hot or boiling water may
be drawn from the boiler. The lower part of the body of the stove
.may be. made of glass, so, that the lamp serves as a source of light
as well as heat. When the body of the stove is of metal we inscrt
near the bottom a piece or pieces of talc through which the state of
the flame can be observed. Instead of supporting the body of the stove
on the lamp, the lamp may be made of nearly the diameter of the
body of the stove and placed in the body, being introduced and removed
from the top. In this case we prefer to employ a chimney to the
lamp, and to furnish the lamp with a wire frame by which to introduce
and remove it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Hinks and Joseph Hinks in the Great Seal
Patent Office on the 11th August 1868.
TO ALL TO WHOM THESE PRESENTS: SHALL COME, we, JAMES
HINKS and JOSEPH HINKS, both, of Birmingham, in the County of 8
Warwick, Manufacturers, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of February, in the
year of our Lord One thousand eight hundred and sixty-eight, in
the thirty-first year of Her reign, did, for Herself, Her heirs, and 3

page_text: successors, give and grant unto we; the said James Hinks and Joseph
Hinks, Her special licence that we, the said James Hinks and Joseph
Hinks, our executors, administrators, and assigns, or such others as we,
the said James Hinks and Joseph Hinks, our executors, administrators,
and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland; the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN PORTABLE
STOVES," upon the condition (amongst others) that we, the said James
Hinks and Joseph Hinks, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under
the hand and scal of one of us or them, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said James Hinks, on behalf of myself
and the said Joseph Hinks, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
thereof, that is to say :-
Our Invention consists in combining or arranging the parts of a
portable stove in the manner herein-after described. Stoves made
according to our Invention are especially suitable for burning
petroleum oil or petroleum spirit, but other liquid combustibles may
be employed.
We construct a portable stove according to our Invention in the
following manner:-The body of the stove consists of a hollow
perforated cylinder of metal, the bottom of which has an opening
sufficiently large to permit of the cone of the burner being passed through
it. The said body is supported above the lamp at the required distance
by means of arms or brackets on the lamp stand.
The lamp is
supported on a stand provided with handles by means of which the
stove may be carried about. A short distance above the flame is a
hollow cone of sheet metal, up which the current of heated air and
products of combustion from the lamp pass, and on the top of the perforated
cylinder a hot water reservoir or boiler fits. The hot water reservoir has

page_text: a conical tube passing through it, up which the current of hot air from
the lamp rises and passes into the room. The cover of the hot water
reservoir and conical tube is so formed that the heated air in passing.
into the room carries with it a portion of steam rising from the water,
and thus keeps the air of the room sufficiently supplied with moisture.
By means of a .tap hot or boiling water may be drawn from the boiler.
The lower part of the body may be made of glass, so that the lamp.
serves as a source of light as well as heat. When the body of the
stove is of metal we insert near the bottom a piece or pieces of talc
through which the state of the flame can be observed.
Having explained the nature of our Invention we will proceed to
describe with reference to the accompanying Drawing the manner in
which the same is to be performed.
Figure 1 represents in elevation, and Figure 2 in vertical section a
portable stove for burning petroleum oil or petroleum spirit or other
liquid combustible constructed according to our Invention; Figure 3
is a plan of the same; and Figure 4 is a horizontal section of the same
taken through the line x, Figure 2. The same letters of reference
are employed to indicate the same parts in each Figure of the
Drawing.
The
a, a, is the body of the stove, the upper part a consisting of a
hollow perforated metal cylinder and the lower part a³ consisting of a
hollow glass cylinder. The part a has a perforated metal bottom a³,
through a hole in the axis of which the burner 6 of the lamp passes,
as represented in Figure 2. The glass part α of the cylindrical body
is strengthened and fixed to the metal part a by the metal straps c.
The reservoir d of the lamp is supported in the hollow stand e.
said stand is provided with a frame of uprights f, to the tops of which
a ring g is fixed. The uprights f carry horizontal arms or brackets g³,
on which the body a, a, of the stove is supported. The body of the
stove is furnished with handles a for the purpose of introducing it
into or removing it from the frame of the stand e. In Figure 2 the
uprights are shown broken off in order to exhibit the way in which
In the
the glass cylinder a is connected with the metal cylinder a.
perforated metal cylinder or body a of the stove is a hollow cone of
sheet metal as, up which the current of hot air and products of com-
bustion from the lamp 6 pass, as indicated by the arrows in Figure 2.
By the position of the lamp b with respect to the body of the stove the

page_text: heat from the said body is not transmitted to the said lamp or to its
reservoir d. In addition to the isolation of the lamp from the body
the position of the said lamp also permits the air for the combustion
of the flame to pass directly through the windguard at the under
side of the burner instead of having first to pass through the body
of the stove before it reaches the lamp, as in the ordinary stove. On
the top of the perforated cylinder a a hot water reservoir or boiler h
fits. In the axis of the said boiler is a conical tube i, up which the
current of heated air rises and passes through the perforations in the
cover into the room. By the passage of the hot air through the
boiler the water therein is heated or boiled. The cover k both
covers the top of the hot water reservoir or boiler h and the conical
tube i, and the said cover is so arranged that the heated air in passing
into the room from the top of the stove carries with it a portion of
the steam arising from the water in the boiler or reservoir h, and
thereby keeps the air of the room sufficiently supplied with moisture.
The way in which the mixture of hot air and steam escapes through
the perforations in the cover k will be understood by referring to
Figure 2. The boiler or reservoir is furnished with a tap / by means
of which hot or boiling water may be drawn from the said boiler or
reservoir. The said tap when the boiler is placed in the body or
cylinder a fits in a vertical slot m in the said body (see Figure 1).
Instead of the hot water reservoir or boiler h an oven for baking
articles of food, or a boiler, or boiler and steamer combined for boiling
and steaming articles of food may be used. In either case the bottom
of the oven or boiler or steamer fits on the top of the cone a³, and
the heated air from the stove is made to circulate about the vertical
sides of the oven or through the axis of the boiler or steamer before it
passes into the room.
When the body of the stove is made partly of metal and partly of
glass, as illustrated in the Drawing, the lamp 6 of the stove serves
as a source of light as well as heat. In such cases we prefer to use
ground or roughened glass for the lower part of the body, an unground
portion being left through which the state of the flame of the lamp
may be examined. Instead of glass tale' or other transparent or semi-
transparent material may be employed. When we make the whole
metal we insert near the
of the cylindrical body of the stove of
bottom a piece or pieces of talc through which the state of the

page_text: flame can be observed.
If required the stand e may be provided
with handles by means of which the stove may be carried about,
but in transporting the stove we find it better to separate the cylindrical
body from tlie stand.
In order to trim the lamp or supply the reservoir with oil or liquid
combustible it is only necessary to lift the body a, a, and boiler / by
means of the handles a vertically from the arms or brackets g³, when
easy access can be gained to the lamp and reservoir.
In the Drawing we have represented our improved duplex burner
applied to the stove, but a. single burner may be used, or more than one
burner, according to the size of the stove and the heat it is required to
obtain.
Having now described the nature of our Invention, and the manner
in which the same is to be performed, we wish it to be understood
that we do not limit. ourselves to the precise details herein described
and illustrated in the Drawing, as the same may be varied without
departing from the nature of our Invention%; but we claim as our
Invention, the improvements in portable stoves herein-before described
and illustrated in the accompanying Drawing, that is to say, arranging
or combining the parts of portable stoves for burning petroleum oil
or petroleum spirit or other liquid combustible, substantially as described
and illustrated.
In witness whereof, I, the said James Hinks, have hereunto set
my hand and seal, this Tenth day of August, in the year of our
T
Witness,
GEORGE SHAW.
JAMES HINKS. (L.s.)
