PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes:
at the Office of the Commissioners of Patents, with his Petition, on the
4th December 1'867.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent
Agents, 123, Chancery Lane, London, do hereby declare the nature of the
said Invention for "AN IMPROVED LIGHTING, HEATING, AND COOKING APPARATUS,.
PART OF WHICH IS APPLICABLE TO OTHER PURPOSES," a communication to me from
abroad by Zoeth Durfee, of Philadelphia, United States of America, to. be..
as follows:-
This Invention relates to an apparatus for cooking and heating food and.
boiling water and other liquids, which apparatus can also be employed for
heating, lighting, or warming rooms and greenhouses, and other similar
purposes.
The apparatus consists of a stand of suitable size and form, on which is
placed a hollow vessel for containing petroleum or other bydrocarbon oil,
which is supplied to the said bollow vessel through a hole closed by a screwed
cap. On the top of this oil vessel are fixed one, two, or more burners
according to requirement, in which are placed felt wicks, which said wicks are

page_text: raised and lowered in the ordinary manner. On the top of the said oil vessel
are three or more projections, on which is placed the heating chamber, the
spaces between the said projections allowing air to pass into the heating
chamber with the flame of the lamp, and thus assist combustion. The heating
chamber is made of metal, and has a perforated metallic diaphragm at its
base for the admission of air, the said diaphragm being provided with slots
through which pass the burners. In the interior of the heating chamber is
placed a strong metal plate also provided with slots corresponding to the size
and number of burners, which said burners pass therethrough into the heating
chamber. Near the top end of the said heating chamber is a grid, on which can
be placed small vessels containing the food or liquid to be heated or cooked.
The top of the heating chamber is provided with projections, on which can
be placed larger vessels containing the food or liquid to be heated or cooked,
the spaces between the said projections serving as passages for the escape of
the waste gases from the heating chamber. At any convenient point in the
said heating chamber is an aperture, over which is fixed talc or other tran-
sparent non-fusible material, so that the state of the flame may be observed
therethrough, and the wicks raised or lowered according to requirement.
Felt wicks can also be applied to any other description of petroleum lamp
now in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Thomas Newton in the Great Seal Patent Office
on the 3rd June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention of "AN IM-
PROVED LIGHTING, HEATING, AND COOKING APPARATUS, PART OF WHICH IS APPLICABLE
TO OTHER PURPOSES," a communication to me from abroad by Zoeth Durfee, of
Philadelphia, United States of America, upon the condition (amongst others)
that I, the said Edward Thomas Hughes, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Edward Thomas Hughes, 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, and accompanying Sheet of Drawings (that is
to say):
This Invention relates to an apparatus for cooking heating and food, and
boiling water and other liquids, which apparatus can also be employed for
heating, lighting, or warming rooms and greenhouses, and for other similar
purposes.
The apparatus consists of a stand of suitable size and form. on which is
placed a hollow vessel for containing petroleum or other hydrocarbon oil, the
said oil being supplied to the hollow vessel through a hole closed by a screwed
cap. On the top of this oil vessel are fixed one, two, or more burners
according to requirement in which are placed felt wicks, which said wicks are
raised and lowered by pinions turned by hand or in any well-known manner:
On the top of the said oil vessel are three or more projections, on which
is placed the heating, chamber, the spaces between the said projections
allowing air to pass into the heating chamber with the flame of the lamp, and
thus assist combustion. The heating chamber is made of metal and has a
perforated metallic diaphragm at its base for the admission of air, the said
diaphragm being provided with slots through which pass the burners, and with
projections corresponding with those ou the oil vessel into which they fit, thus
keeping the heating chamber securely in position. In the interior of the
beating chamber is placed a strong metal plate also provided with slots cor-
responding to the size and number of burners, the said slots being cut or cast
in projections on the said plate which serve as chimneys and into which the
burners pass.
Near the top end of the said heating chamber - is a grid on
which can be placed small vessels containing the food or liquid to be heated
or cooked, and the top of the heating chamber is provided with projections

page_text: on which can be placed larger vessels containing the food or liquid to be
heated or cooked. At any convenient point in the said heating chamber is
an aperture, over which is fixed a talc or other transparent non-fusible
material, so that the state of the flame may be observed therethrough, and
the wicks raised or lowered according to requirement. A. plate of metal. or
other material is placed over the said. grid; which aids the consumption of the
smoke or gases issuing from the flame, thereby preventing all smell arising
from the apparatus. Felt wicks can also be applied to any other description
of petroleum lamp now in use.
In order that this Invention may be more clearly understood, I have
annexed the accompanying Sheet of Drawings,. on which Fig. 1 is a sectional
elevation of the apparatus, and Fig. 2 a plan of the same.
A is the stand on which the oil vessel rests; B, the hollow vessel for
containing the oil; C, the aperture through which the said vessel is supplied
with oil; D, the burners containing the felt wicks d; E, the pinions, and
F, the thumbscrews for raising and lowering the said wicks; G, the projec-
tions on the oil vessel for supporting the heating chamber; H and I, thé
corresponding projections on the heating chamber; J, the perforated metallic
diaphragm for the admission of air; K, the metal plate with the projections L,
into which the burners D.pass;. M, the grid, on which may be placed small
vessels containing the food or liquid to be heated or cooked; N, the casting
fitting into the top of the heating chamber, having projections for 'supporting
larger vessels; O, the aperture for observing the state of the flame; and P,
the plate for aiding the consumption of the smoke or gases and preventing
smell.
Having now described the nature and particulars of the said Invention,
what I claim as new and useful and desire to secure by Letters Patent is, the
apparatus for lighting, heating, and cooking, as herein described and illus-
trated in the accompanying Sheet of Drawings, also the application of felt
wicks to petroleum lamps.
In witness whereof, I, the said Edward Thomas Hughes, have hereunto
set my hand and seal, this Third day of June, in the year of our
