PROVISIONAL SPECIFICATION left by the said John Henry Johnson at the
Office of the Commissioners of Patents, with his Petition, on the 20th
October 1862.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, and of 166, Buchanan Street, in the City of Glasgow, North
Britain, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR BOILING LIQUIDS AND COOKING OR PREPARING
FOOD, APPLICABLE ALSO AS A NIGHT-LIGHT," a communication from abroad
by Anthony Pollak, of the City of Washington, in the United States of
America, to be as follows:-
This Invention relates to a peculiar construction and arrangement of
apparatus to be heated by a lamp or gas jet for the purpose of boiling water
or other liquids, and for cooking, warming, or preparing food, the same
apparatus serving also as a night-light for a sick room or nursery.

page_text: According to this Invention it is proposed to combine a vessel or receiver
for the liquid to be boiled or heated with a lamp or gas jet in such a manner
as, to allow the chimney of the lamp or gas flame to pass up the centre of the
vessel and be surrounded by the liquid contained therein. The chimney may
be made either entirely of metal, or the lower part thereof which is attached
to the lamp or burner may be of glass or other transparent material; when
composed entirely of metal a window or aperture is made in the lower part
through which the light may shine into the apartment. A tap may be fitted
to the lower part of the vessel for the purpose of drawing off the heated
liquid or it may be provided with a pouring lip or spout. In some cases an
annular cup may be fitted into the upper part of the vessel so as to surround
the top of the chimney for the purpose of containing infants' food, and a tripod
or stand is situate over the top of the chimney on the lid of the vessel to receive
a dish or plate in which meat or eggs may be fried. The upper part of tho
chimney and the vessel are united at their lower rims so as to form one piece,
which fits accurately over the lower portion of the chimney immediately
surrounding the flame, and is readily removeable therefrom when desired.
When used with a gas burner an ordinary side bracket fitting may be
employed, with a separate stout bracket above fitted with a ring for holding
the apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on the
20th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HENRY
JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex, and of
166, Buchanan Street, in the City of Glasgow, North Britain, Gentleman,

John Henry Johnson, my executors, administrators, or assigns, should at.
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use,

page_text: exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR BOILING LIQUIDS AND COOKING OR PREPARING FOOD, APPLICABLE
ALSO AS A NIGHT-LIGHT," a communication from abroad by Anthony Pollak,
of the City of Washington, in the United States of America, upon the
condition (amongst others) that I, the said John Henry Johnson, my
executors or administrators, by an instrument in writing under my, hand
and seal, or under the hand and seal of one of 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 John Henry Johnson, do hereby declare
the nature of the 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, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say :-
The said Invention relates to a peculiar construction and arrangement of
apparatus to be beated by a lamp or gas jot or jets for the purpose of boiling
water or other liquids, and for cooking, warming, or preparing food, the same
apparatus serving also as a night-light for a sick room or nursery.
According to this Invention it is proposed to combine a vessel or receiver
for the liquid to be boiled or heated with a lamp or gas jet or jets, in such a
manner as to allow the chimney of the lamp or gas flame to pass up the
centre of the vessel and be surrounded by the liquid contained therein. Tho
chimney may be made either entirely of metal, or the lower part thereof which
is attached to the lamp or burner may be of glass or other transparent
material; when composed entirely of metal a window or aperture is made
in the lower part through which the light may shine into the apartment.
A tap may be fitted to the lower part of the vessel for the purpose of drawing
off the heated liquid, or it may be provided with a pouring lip or spout. In
some cases an annular cup may be fitted into the upper part of the vessel so
as to surround the top of the chimney for the purpose of containing infants'
food, and a tripod or stand may be placed over the top of the chimney on the
lid of the vessel to receive a dish or plate in which meat or eggs may be fried
or warmed. The upper part of the chimney is united to the lower rim of the
vessel so as to form one piece therewith, which fits accurately over the lower
portion of the chimney immediately surrounding the flame, and is readily
removeable therefrom when desired. When used with a gas burner an.

page_text: ordinary side bracket may be employed, with a separate stout bracket above
fitted with a ring for holding the apparatus.
And in order that the said Invention may be fully understood, I shall
now proceed more particularly to describe the same, and for that purpose
I shall refer to the several Figures on the Sheet of Drawings hereunto
annexed, the same letters of reference indicating corresponding parts in both
Figures.
Figure 1 of the annexed Sheet of Drawings represents a vertical section
of one form of the improved apparatus as adapted on a comparatively small
scale for use in the nursery or sick room, the heat being derived from a small
lamp; and Figure 2 is a similar view of the apparatus constructed on a larger
scale and heated by gas jets, this modification being intended as a boiler or urn
for saloons or restaurants. In these two Figures A represents a vessel in
which water or other liquid is heated by the aid either of a paraffin or other
lamp B, as in Figure 1, or by one or more gas jets as shown in Figure 2,
C is a chimney passing through the centre of the vessel A; it is composed
either entirely of metal, or the other part which is contained within the vessel
is of metal, whilst the lower part or bulb c which surrounds the flame is
composed of glass or other suitable transparent or translucent material.
When the bulb c is composed of metal it is to be provided with one or more
apertures covered with glass or tale d, d, through which a light is thrown into
the apartment and facility is afforded for inspecting the state of the flame.
The lower part or bulb c is fixed in any convenient manner to the gallery of the
lamp B (see Figure 1), or is supported in a stand E (Figure 2), but in all
cases it is separate from the upper portion of the chimney which is secured
at a, a, by soldering, brazing, or otherwise, to the rim or edge of the bottom
of the vessel A, this portion of the chimney being expanded at the part in
question for that purpose as shewn in the Drawings. The vessel A and the
upper part of the chimney consequently form one piece, which rests upon the
upper rim.or edge of the bulb or lower portion c of the chinney and may be
readily fitted thereon or removed at pleasure. In Figure 2 the part c consists
of a cylindrical casing of sheet metal or other suitable material provided with
à bottom of perforated metal or wirework e for the free admission of air to the
gas burners, which pass through openings made for that purpose in the bottom
of the casing, and are connected by branch pipes f, fitted with a stop-cock g
to a flexible or other gas pipe h. In the larger sized apparatus a sufficient
base is obtained for supporting the vessel or boiler A safely upon the upper
rim of the case c, but in the smaller apparatus it is found advisable to employ
a stand consisting of two or more vertical supports h', h', secured to a small,

page_text: tray i, and having an annular support or socket k fitted to their upper ends,
within which socket the vessel A (which may be made slightly conical or
tapering towards the bottom) rests, the ring k thus supporting the entire
weight of the vessel. A pouring lip or spout 1, and handle m, may be fitted
to the smaller vessels, whilst those of a larger make are provided each with a
tap or cock n for drawing off the contents. The smaller apparatus may also
be arranged to be heated by an ordinary gas burner, a supporting bracket
being provided, having a ring in which the vessel is to be placed over the
gas burner. A vessel having a central flue as herein-before described may
be used with any ordinary lamp and glass chimney by simply slipping it over
the glas chimney of the lamp, in which case the lower part or bulb c will be
dispensed with.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion, that what I consider to be novel and
original and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent, is,-
First, the general constructions and arrangements of apparatus for boiling
liquids, and for cooking and preparing food, substantially as herein-before
described.
Second, the peculiar combination of lamp chimney or vertical central
flue and vessel with any ordinary lamp or gas burner as herein-before
described.
Third, the making of the upper part of the chimney and the vessel with
which it is connected so as to fit on to the lower part or bulb, which latter may
be either of metal or glass provided or not with one or more windows or light
apertures as herein-before described.
In witness whereof, I, the said John Henry Johnson, have hereunto set
my hand and seal, this Twentieth day of April, One thousand eight
hundred and sixty-three.
