IMPROVEMENTS IN THE MEANS OF AND APPARATUS FOR BOILING AND COOKING
Year: 1863

page_text: LETTERS PATENT to George Rand, of Stoneham, in the County of Hants,
for the Invention of "IMPROVEMENTS IN THE MEANS OF AND APPARATUS
FOR BOILING AND COOKING."
Sealed the 12th January 1864, and dated the 16th July 1863.
PROVISIONAL SPECIFICATION left by the said George Rand at the
Office of the Commissioners of Patents, with his Petition, on the
16th July 1863.
I, GEORGE RAND, of Stoneham, in the County of Hants, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE MEANS OF AND
APPARATUS FOR BOILING AND COOKING," to be as follows :—
This Invention consists of certain improvements in the means of and
apparatus for boiling water and cooking generally. I propose to employ as a
means of generating heat for boiling and cooking any of the oils in ordinary
use for illuminating purposes, such as petroleum, paraffine, or other mineral
oil, or the animal or vegetable oils, or any of the hydrocarbons, such as naptha
or camphine.
I propose to employ flat wicks in corresponding holders fixed at the lower
part of the apparatus and set in suitable receivers, or oil holders, which may
be raised or lowered by means of toothed gearing, in order to heat the
apparatus above them to the desired temperature.
The apparatus consists of a vertical boiler of metal, having a conical funnel
or chimney passing through the centre, the chimney being situated over the
wicks of the lamps, the bottom of the chimney is partly closed by a metallic
circular plate, in which niches, slots, or elongated apertures are cut to receive

page_text: the flame from the flat lamp wicks. The heat passes up the chimney, and the
boiler having been filled with cold water surrounding the flue, the water, will
rapidly be raised to the boiling temperature, and can be withdrawn by means
of a tap, or be adapted to the steaming of potatoes or other articles of food by
placing them in a suitable receptacle attached to the upper part of the boiler,
and communicating therewith by a pipe and valve or other regulating
equivalent.
On the top of the chimney, which is formed in a tooth-like or serrated form,
or which top may have its circumference perforated with holes to permit of
the requisite current or draught of air, I propose to place a metallic dish or
pan for the purpose of frying meat, or else a saucepan for boiling meat or
vegetables. By this arrangement of apparatus water may be boiled with a
rapidity not hitherto attainable by means of gas cooking apparatus, and the
various operations of cooking can be accomplished at a mere nominal expense,
and without any effluvium or smoke resulting, or communicating any unpleasant
flavour to the articles, as in the case when gas is used. Moreover, the appa-
ratus itself as well as the oils is exceedingly cheap, and the whole is moveable
or portable, and can be moved or changed from one position to another,
os desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Rand in the Great Seal Patent Office on the
16th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
RAND, of Stoneham, in the County of Hants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of July, in the year of our Lord One
thousand eight. hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Rand, Her special licence that I, the said George
Rand, my executors, administrators, and assigns, or such others as I,
the said George Rand, my 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 "IMPROVE-
MENTS IN THE MEANS OF AND APPARATUS FOR BOILING AND COOKING," upon
the condition (amongst others) that I, the said George Rand, my executors

page_text: 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 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 George Rand, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My Invention consists of certain improvements in the means of and apparatus
for boiling water and other liquids, and cooking. I employ as the means of
generating heat for boiling and cooking any of the oils in ordinary use for
illuminating purposes, such as petroleum, paraffine, or other mineral oil, or the
animal or vegetable oils, or any of the hydrocarbons, such as naptha or
camphine.
I use flat wicks in corresponding holders fixed at the lower part of the
apparatus, and set in suitable receivers or oil holders, which may be raised or
lowered by means of toothed gearing in order to heat the apparatus above
them to the desired temperature.
In order to describe my said Invention as completely as possible, I now
proceed to explain the same with reference to the accompanying Sheet of
illustrative Drawings, and to the figures and letters of reference marked
thereon, as follows:-
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a front elevation of the apparatus, and Fig. 2 a plan view
taken through the line A, B.
a, a, represents a vertical cylindrical boiler resting upon the stand b, b,
which contains the flat wick holders c, c, (shewn in dotted lines at Fig. 2)
mounted on the top of the oil reservoir d; the wicks are raised and lowered
by means of the ordinary method of wheels and milled edged buttons e, e.
The reservoir is to be filled through a tube f, closed by a screw cap g. Within
the boiler a a conical chimney h (shewn in dotted lines) is fixed to the bottom
plate of the boiler and passes centrally above and through the cover i, as shewn,
which cover is moveable by the knobs j, j, in order to permit the boiler to be
filled with water or other liquid to be heated. The contents of the boiler are
withdrawn by means of the tap or cock k. The top of the boiler is furnished
with a rail 7, 1, supported by arms 'm, m, on which a metal dish or pan n may

page_text: be placed for the purpose of frying. The bottom plate of the boiler within
the circumference of the base of the chimney has niches, slots, or elongated
apertures c', c', shewn in dotted lines, Fig. 2, corresponding with the form and
position of the wick holders. The boiler may be lifted from the stand by
handles or rings o, o, and the entire apparatus may be carried by similar
handles p, p, or if preferred by ordinary rigid urn handles. It will be evident
that when the lamp is lighted the heat of the flame will be carried up the
chimney, surrounded by water or other liquid which will speedily be caused to
reach a boiling temperature. The combustion is aided by the draught of air
rushing through the apertures q, q. The heat is so great that meat or other
food placed in the pan over the chimney may be cooked in a comparatively
short time. By the construction of this apparatus, it is obvious that all the
operations of a gas cooking apparatus may be performed at a merely nominal
expense, and without any effluvium or smoke resulting, or communicating any
unpleasant flavour to the food, as is sometimes the case when gas is used.
Moreover, the apparatus itself as well as the oils are exceedingly cheap. The
apparatus may, however, be made of a very ornamental character, according to
taste. It may be of block tin, or copper, or other metal.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark in conclusion that I do
not limit myself to thé précise details and configuration of parts herein expressed
and shewn, as the same may be varied or modified without departing from the
principles upon which my Invention is based; but what I claim as my Inven-
tion, and desire to be secured to me by the herein in part recited Letters
Patent are the general arrangement and combination of parts, substantially as
herein specified and illustrated, constituting an improved apparatus for boiling
and cooking.
In witness whereof, I, the said George Rand, have hereunto set my
hand and seal, this Eleventh day of January, in the year of our
Lord One thousand eight hundred and sixty-four.
