1, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS RELATING TO APPARATUS FOR UTILIZING THE
HEAT FROM LAMPS OR CANDLES FOR HEATING FOOD OR OTHER SUBSTANCES," to be
as follows:
This invention has for its object to utilize the heat generated by the burning of
lamps or candles, for heating liquids, food and other substances.
In carrying the said invention into practice a grate, made of sheet-metal strips,
which are placed edgewise and are preferably arranged radially around a common
centre, is fixed above the glass-chimney of the lamp or at a suitable distance above
the flame of the candle, and supports the vessel for containing the liquid or other
substance to be heated.
This grate may be fixed upon a lamp-chimney, by means of a metallic cylinder,
rigidly secured to the underside of the grate and designed to enclose the top end
of the chimney. To the edge of the circular grate is fastened a metallic border or
ring, the upward bent flange of which maintains the said vessel in its position.
To enable the cylinder to fit lamp-chimneys of different diameters, three or more
plate springs are sometimes secured to the inside of the said cylinder. For the
same purpose, the cylinder is sometimes formed of several strips, fixed to the ends
of rods, which are movable in guides connected to the underside of the grate; by
pushing the said rods towards the chimney until the strips touch the same, the
grate is fastened in its position. Another means for applying the strips, into
which the cylinder is divided, to the chimney .consists in suspending the said
cylinder by means of its inward bent top edges upon the top.end of the chimney,
and in connecting each strip by means of several links with the circular grate; in
this case, the grate obviously does not rest upon the chimney and may be replaced
by a ring.
":
When it is intended to cause the grate to be supported, by the shade or the
globe of a lamp, or by the top portion of a candlestick, an annular, disc is placed

page_text: upon the said objects, and as the portion of the chimney overtopping the shade or
globe as well as the candles are of different lengths, the grate, which in this case
also may be ring-shaped, is connected to said disc by means of supports, the length
of which can be varied at will; supports of this kind are toggle-joints and hollow
cylinders enclosing each other.
In order to prevent any liquid which overflows from the vessel to be heated
from dropping upon the lamp or candlestick, the ring surrounding, or used as a
substitute for the grate, is sometimes made gutter-shaped.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
1
This invention relates to apparatus for enabling the heat generated by the
burning of lamps or candles to be utilized for beating liquids, food and other
substances. +

The improved apparatus is applicable to lamps or candlesticks of any construction
and is adapted to support a cooking vessel or the like at a suitable distance from
the flame.without the said vessel being coated with soot.
The said apparatus is carried either by the chimney, the globe, or the shade of a
lamp; or by the upper part of a candlestick, the fastening devices being corre-
spondingly modified.
'
In the accompanying drawing, the figures of which are hereinafter described,
I have represented various modifications of my improved apparatus.
:
The said apparatus consists essentially of a support or platform which is placed
at a suitable distance from the flame, and which, either directly or indirectly,
serves to carry the cooking vessel.

་
The simplest form of my apparatus adapted to be applied to lamps, is represented
in Figures 1, 2 and 3, Figure 1 being an elevation, Figure 2 a longitudinal section,
and Figure 3 a plan:

page_text: This apparatus consists of a metallic cylinder A which is provided at its upper
end with the cross.bars.a by which it is supported upon a lamp-chimney. The
metallic cylinder A, at the part extending above the lamp-chimney, is provided
with openings a¹, which permit the escape of the hot air passing from the flame of
the lamp when a cooking vessel B is placed upon the apparatus, thereby preventing
the direct escape of the products of combustion in a vertical direction.
In order to adapt the described apparatus for use with lamp-chimneys of
different diameters, it is advantageous to provide on its inner side three or more
springs b (see figure 12), which when the apparatus is applied to a lamp-chimney,
press against the latter.
Instead of using a metallic cylinder, I can employ three or four strips A¹ for
supporting the apparatus upon the lamp-chimney.
Figures 4 and 5 illustrate such a mode of fastening, Figure 4 being a vertical
section of the apparatus, and Figure 5 a plan.
Figures 9, 10 and 11 illustrate a modification, Figure 9 being a vertical section,
Figure 10 a section on the line x x figure 9, and Figure 11 an underside view.
In order that these devices shall be applicable to chimneys of varying diameters,
the strips A¹ are either adapted to slide horizontally as shown in Figures 9 and 11;
or they are each connected by means of two links c of equal length with the angle-
plates a serving as the support for the cooking-vessel B.
In the former case the apparatus is supported upon the chimney by the bars a
carrying the cooking vessel B, and in the latter case by the inwardly extending
upper ends of the strips A'. The pressing of the strips A¹ onto the lamp-chimney
is automatically effected, in the apparatus represented in figures 4 and 5, by the
weight of the same, while in the modification shown in figures 9 and 11 it is effected
by displacement of the bars c¹ carrying the strips A¹. This displacement can
also be effected, as is easily understood through the medium of suitably arranged
screws.
If the apparatus is to be carried by the shade or globe of a lamp instead of by
the chimney, it is connected by stays with a disc D which is fixed upon the globe
or shade. As the length of chimney protruding above the globe or the shade
varies in different lamps, and as the bars a carrying the cooking vessel B must
always be at a suitable height above the chimney, it is advantageous to arrange
the said stays in such a manner that the distance of the bars a from the disc D can
be varied according to requirements. This can be attained by arranging the stays
in a similar manner to the levers of lazy-tongs, as represented in figures 7 and 8 in
elevation and plan respectively; or by connecting the disc D with the device
carrying the cooking vessel by cylinders telescoping one within the other and
adapted to be fixed in different positions, as illustrated in elevation in Figure 6.
The apparatus represented in figures 7 and 8 is also adapted for use upon a
candlestick.
In order that the heat shall properly act upon the cooking vessel, the latter is
supported upon the metallic bars a which are of sufficient depth to maintain the
said vessel at a proper distance above the chimney. It is of advantage in some
cases, for instance in heating milk, to arrange vertically above the lamp chimneys,
at a suitable distance therefrom, a small plate d, so that the hot air and the
products of combustion passing from the chimney do not impinge directly against
the cooling vessel.
For the purpose of preventing drops of liquid from entering the lamp-chimney,
in case the liquid in the vessel B should boil over, it is advantageous to enlarge
the upper part of the cooking vessel, so that the cover does not lie upon the rim
of the vessel but is inserted in the rim (see Figure 1).
For
With this arrangement the liquid can only run over the sides of the vessel when
it has collected above the cover up to the level of the rim of the said vessel.
the further protection of the lamp-chimney, the ring E, carrying the cross-bars a,
is made in the form of a channel which receives any liquid which may run over
the edges of the cooking vessel.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what I claim is
First. Apparatus for the utilization of the heat generated by the burning of
lamps .or candles, for heating food and other substances, the said apparatus
.consisting of a support for a vessel B, which support is composed of metallic bars a
of suitable depth, and is attached to a metallic cylinder A which can be placed
over the lamp-chimney and which at its upper rim is provided with openings for
'the escape of the hot air and products of combustion from the lamp-chimney
(substantially as described with reference to Figures 1, 2, 3 and 12), or to a frame
having adjustable strips A¹ adapted to be pressed against the lamp-chimney,
.substantially as described with reference to Figures 4, 5, 9 and 11; or is connected
by means of stays, or of cylinders capable of sliding one within another, with a
disc D (Figures 6, 7 and 8) so that the said support can be fastened to the chimney,
'the globe, or the shade of a lamp, or to, the upper part of a candle-stick.
Second. In apparatus of the class described in the preceding claiming clause
