PROVISIONAL SPECIFICATION.
Improvements in Gas or Oil Lighting, Heating, and Cooking
Apparatus.
I, THOMAS BOYDELL, of 1, Vincent Street, Bolton, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to utilize the waste heat from gaslights or oil lamps
used for illuminating purposes, without altering the fittings of the same, without
interfering with the use of the light for illumination, or causing any more smoke
or smell than comes from the ordinary open gaslight or oil lamp.
To the globe holder of an ordinary gas pendant, bracket, chandelier or the
like, I affix a metal stand, formed as follows.
A narrow circular ring, of diameter and size to fit various sizes of globe holders
is connected by one, two, or more upright or curved pillars to another elliptical
or circular band of a diameter or size to allow of a small kettle or dish to fit thereon
at a suitable height above the flame to prevent any smoke or smell, or to prevent
the light from shining into the room.
In another stand, I make the bottom part of stand to screw upon the gas socket.
The sides of both of these previously mentioned stands are open, to allow the
light to shine into the room.
For baking, frying, or warming, light cakes, meat or the like, I use a larger
light metal plate or wire stand, which fits loosely but firmly upon the top of any
of the other mentioned stands.
In a combined globe and stand, I use a globe made of glass or other transparent
or semi-transparent heat resisting material. To the top of this globe I attach per-
manently a light raised stand made of any fire resisting material, but preferably
metal. The top of this stand is open to receive a small kettle, pan or the like, to
be heated by the flame underneath and the superfluous heat passes out through
the sides of the stand raised above the globe. The globe is fastened at the bottom
to any ordinary globe holder.
In another modification, I make the stand to fit loosely on the top of the globe,
so that the stand can be removed from the globe when not required for cooking
or heating.
In another combined globe and stand, I use a globe formed of a light framework
of metal, with either sliding or fixed panels of coloured or plain glass or other
transparent or partially transparent material in the sides. The bottom part of
framework is made either to screw upon the gas socket or fit upon the globe holder.
The top of this framework globe is continued above the panels with a raised stand
with open sides, fixed at a suitable height to receive a kettle or the like.
It will thus be understood that this apparatus can be instantly attached to the
socket or globe holder of any ordinary gaslight or oil lamp. That during darkness
only one light is necessary in a room for illuminating, heating, or cooking pur-
poses. That it is available in emergencies or sickness when there is no fire in the
house, and with only the cost of one light for illuminating, heating or cooking,

page_text: and these it will accomplish without any more smoke or smell than comes from
the ordinary open gaslight or oil lamp.

Improvements in Gas or Oil Lighting, Heating, and Cooking
Apparatus.
I, THOMAS BOYDELL, of 1, Vincent Street, Bolton, in the County of Lancaster,
Engineer, 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, that is to say:-
In the production of light by the use of gas-lamps, oil-lamps or similar illu-
minating means, a considerable amount of heat is generated during the process
of combustion of such illuminant, and is, under ordinary circumstances allowed
to diffuse into the atmosphere without being put to any use as a heating medium.
To utilize this heat which is usually wasted, by the application of means to the
gas or oil lamp or bracket whereby said heat may be made to perform the functions
of heating or cooking, and that without affecting or diminishing the illuminating
power of the flame, is the object of this invention,, which is attained as hereinafter
described.
In order that my said invention may be readily understood, I have hereunto
appended sheets of drawings illustrative thereof, in which:-
Fig. 1 is an elevation of parts illustrating the application of my invention to
an ordinary gas bracket.
Fig. 2 is a view of parts shewn by Fig. 1 as seen from beneath.
Fig. 3, 4, 5 and 6 illustrate modifications of the arrangement shown by Figs. 1
and 2.
Figs. 7, 8 and 9 are top and side views of parts which may be used in addition
to the other parts of my invention.
Fig. 10 is an elevation showing how my invention may be applied to the globe
of a gas or oil lamp.
Figs. 11 and 12 are modifications of the arrangement illustrated by Fig. 10.
Figs. 13, 14 and 15 are detail drawings of parts hereinafter referred to.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying my invention into effect, I make use of a stand or holder for sup-
porting a kettle or like utensil consisting of an annular or other suitably shaped
piece of metal or other substance a connected by an arm or arms 6 with a base
piece c, said base piece being either of the form shown by Fig. 1'and taking over
a part c¹ (see Figs. 13 and 14) screwed on to the ordinary gas bracket d, or similar
to that illustrated by Figs. 3 and 5, in which case the part takes on to or rests
upon the gallery e which in an ordinary way supports the globe k. Suitable handle
parts g may be fixed to the parts a, b or c to facilitate the placing into position or
removal of the said stand.
Again the annular part a for holding the kettle etc. may be detachably supported
by means of the parts 61 resting upon the flange h formed on the inner or outer
periphery of an ordinary kind of globe k (as shown by Fig. 10) or the part a may
be securely attached to or made integral with the upper part of the globe k as
shown by Fig. 11, in which case suitable openings are made in said globe k for
the passage of the products of combustion from the burner within. Further, said

page_text: annular piece a may be carried by the upright parts 6, said upright parts extend-
ing from the base piece of the globe to the ring a, thus forming a suitable frame-
work by which the separate panels of the globe k are held in position; in this
manner it allows these panels to be of any one colour or of varied colours of glass
or other transparent or semi-transparent material or substance suitable for the
purpose. Or this arrangement of framework and panels may be used without the
upper ring a if desired, thus a globe for ordinary lighting purposes is produced.
If desired under certain conditions of heating or cooking, plates op of metal
or other suitable material formed as shown by Figs. 7, 8 and 9 may be placed on
or within the annular piece a.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
-
1. The improved device for heating and cooking purposes constructed and
arranged substantially as specified.
2. Means for utilizing an ordinary gas flame for lighting, and heating purposes,
the same being constructed substantially as herein specified.
