PROVISIONAL SPECIFICATION.
Improvements in Means for Saving and Utilizing the Heat from an
Ordinary Gas Jet, or Paraffin Flame, or Oil Burner.
ALEXANDER CARR Surgeon 150 Wells Road Bristol do hereby declare the
nature of this invention to be as follows:-
A hollow sphere or segment of a sphere made of fire clay burnt or baked in kiln
or oven or other suitable material pierced with one, two, or more apertures & of
dimension varied as required.
I intend this to be so placed as to surround a gas jet or burner, or any lamp
for burning oil whether mineral or vegetable, with the intent of saving the heat
given off & utilizing the same by increasing the area of heated surface with which
air comes in contact.

COMPLETE SPECIFICATION.
Improvements in Means for Saving and Utilizing the Heat from an
Ordinary Gas Jet, or Paraffin Flame, or Oil Burner.
I, ALEXANDER CARR of 150 Wells Road, Bristol, Surgeon, 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:—
My invention has for its object to provide improved means for utilising the heat
from a burner (such as a gas burner, or a mineral, or vegetable oil burner) for
warming apartments or for other heating purposes. According to my invention I
provide the gas, or other burner, with a hollow sphere or segment of a sphere, or
equivalent chamber, which will enclose the flame, the said chamber being of any
suitable form and made of any suitable material such as burnt or baked fireclay or
earthenware, or copper, or like material or metal, which will take up and give off
the heat from the flame. It is pierced with a hole, or with holes to admit of the
circulation of air through the said chamber. When the gas jet, or the like is
lighted the heat therefrom by impinging on the walls of the surrounding chamber,
heat the said chamber to a high degree, so that the surrounding air, by impinging
against the outer surface of the chamber becomes heated and is diffused throughout
the apartment in which it is situated. The accompanying drawing illustrates in
section an approximately spherical chamber according to my invention as applied
to an ordinary gas burner, from which it will be readily understood that it may be
of any convenient shape, and that it may be applied to an oil, or other lamp burner
or burners. A is the burner and B a gallery, or support, such as can be used for
the ordinary globe when the heating device is not required to be used, but which
gallery is also utilised for supporting the heating device C when in use.
The heating device consists of a chamber of a spherical, or partly spherical form,
as shewn, or of any other convenient, or suitable shape. I generally prefer to
make it of copper on account of its lightness, but it may be made of fireclay, or
other refractory, or suitable material which will give the desired heating effect,
and if desired the chamber may be made in parts for convenience of manufacture,
the parts being fitted together by screwing one part to, or into the other, or others
or in any other convenient manner. When the gas jet is lighted the heat therefrom
is imparted to the material of which the chamber C is made which thus becomes
Prins 27

page_text: highly heated so that the air surrounding the chamber by impinging against its
outer surface becomes heated, whilst air entering the interior of the chamber
passes out through the perforations D, therein into the surrounding apartment
whereby the said apartment becomes efficiently warmed more readily than would be
the case if the gas jet were not provided with the chamber C. The apparatus will
be found useful for heating rooms, or apartments, which are not provided with fire-
places, or in cases where it is required to raise the temperature of a room rapidly,
or to heat a room only to a slight degree, as the temperature may be regulated by
regulating the size of the flame. It will also be found useful for sick rooms, and
for drying damp rooms.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. As a means for utilising the heat from gas, or other burners, a chamber for
enclosing the burner, the said chamber being of a material which will become highly
heated by the flame from the burner and impart heat to the air circulating around
it, substantially as hereinbefore described.
2. For utilising the heat from gas, and other burners a chamber for enclosing
the flame from a burner the said chamber being composed of a material which will
become highly heated and being provided with a perforation or with perforations
through which air entering the chamber and becoming heated passes into the
apartment outside the chamber to assist in heating the surrounding air substantially
as herein before described.
