PROVISIONAL SPECIFICATION.
A Device or Apparatus for the Useful Employment of the Waste Heat
given off from Gas and other Burners and Stoves.
I, JAMES THOMAS SPENCER, of 25 and 27, London Road, Reading, in the County
of Berkshire, Ironmonger and Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention consists of a device or apparatus adapted to be fixed upon and
above any ordinary gas or oil burner employed for illumination, for the purpose
of distributing or radiating the otherwise waste heat given off therefrom in order
to heat the air and generally to warm the room or compartment in which such
burner is situated without deteriorating the illuminating power of such burner,
the same device or apparatus being also applicable for use upon certain gas and
oil stoves for like and similar purposes.
When used in connection with gas or oil burners employed for illuminating
purposes, my invention consists of a metallic chamber preferably circular in plan,
and having a domed or other shaped air tight roof, and provided at its lower end
with a circular or other shaped opening having a suitable flange inside the said
chamber. The said chamber may be adapted to be suspended above and over
the burner, or be seated upon a suitable gallery screwed upon or otherwise con-
nected to the said burner, the said gallery, when used, being so arranged the the
globe of the burner may rest in position therein beneath the said chamber in order
that the burner may be used for illuminating purposes undeteriorated by the
presence of the said chamber.
The said chamber has at its lower end any number of small holes or perforations,
or a surface of wire gauze through which the heat from the burner may escape,
and between the said holes, perforations or wire gauze and the before mentioned
hole in the bottom the said chamber is provided with any number of vertical
tubular passages extending through the roof and bottom of same, and the said
tubular passages by becoming heated by the flame of the burner would heat the
atmospheric air therein which by convection would rise and escape out at the
top of the said tubes into the room or compartment while fresh air would enter
the lower ends of the said tubes, thus providing the said compartment with heated
pure air uncontaminated by the carbonaceous fumes from the burner.
For bath and other purposes where heated water may be required, I may
dispense with the said tubular passages, and provide within the said chamber one
or any number of coils of copper or other tubing, arranged in spiral or other
form or forms around about and above the said burner, the initial end or ends
of the said tube or tubes being connected outside the chamber with a preferably
cock-governed water supply, while the final end or ends of same may terminate
outside the chamber in the form of a spout or tap from which the water may flow
or be otherwise withdrawn as heated.
In connection with gas or oil stoves either of the said devices may be arranged
to fit upon and partly or wholly cover the said stove or be otherwise placed in

page_text: connection therewith so that the whole or a portion of the heat therefrom may
be used in like manner for the purposes stated.

A Device or Apparatus for the Useful Employment of the Waste Heat
given off from Gas.and.other.Burners and Stoves.
I, JAMES THOMAS SPENCER, of 25 and 27, London Road, Reading, in the County
of Berkshire, Ironmonger and 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:-
My invention consists of a device or apparatus adapted to be fixed upon and
above any ordinary gas or oil burner employed for illumination, for the purpose
of distributing or radiating the otherwise waste heat given off therefrom, in order
to heat the air and generally to warm the room or compartment in which such
burner is situated without deteriorating the illuminating power of such burner,
the same device or apparatus being also applicable for use upon certain gas and
oil stoves for like and similar purposes.
In order that my said invention may be fully understood reference is herein-
after made to the appended drawings, of which,
Fig. 1 is a part sectional elevation of my improved apparatus for attachment
to an illuminating gas burner, Figs. 2 and 3 being top and bottom plan views
respectively of the same.
Fig. 4 is a part sectional elevation of an apparatus for heating water, according
to my invention and hereinafter explained, Fig. 5 being a section of same upon
the line AB.
Referring to Figs. 1, 2 and 3, which relates to an apparatus for distributing
and heating the air of a compartment by the employment of the otherwise waste
heat given off from an ordinary gas burner, I mount upon a bracket or other burner
such as A a suitably shaped wire or other metallic frame or gallery B, adapted
to receive and carry a suitable gas globe C (shewn by dotted outline in Fig. 1).
The said frame while serving to form a gallery for the globe C is also so arranged
at its upper surface as to carry above and clear of the said globe, so as not to
obstruct the light given off therefrom, a cylindrical
chamber D, having a dome or other shaped air tight cover D¹ (Fig. 2) and a
or other shaped metallic
like bottom D2 (Fig. 3) in the latter of which is formed a preferably circular
opening E, through which the heat from the burner A may enter the chamber D,
the said opening E thus converting the said bottom D2 into a sort of broad flange,
in which are formed any number of circular holes F, while in the roof D are a
like number of similar holes G coinciding in position with those in D³, and each
hole G in D is connected by a metallic tube H to the corresponding hole F in D³,
the two ends of each of the said tubes being burred over upon the said top and
bottom or otherwise arranged so as to form a perfectly air-tight joint.
From the foregoing it.will be understood that the otherwise waste heat given
off from the burner A, would enter and rise up into the chamber D through the
aperture E, and heat the tubes H, so that the cold air entering into the lower
ends of the said tubular passages would immediately become heated, and by
convection would rise and escape out at the top ends of same into the room or

page_text: compartment, while fresh air would again enter into the lower ends, thus pro-
viding the said compartment with heated pure air uncontaminated by the
carbonaceous fumes from the burner.
I may provide upon the outer surface of the roof D¹ a hook or its equivalent,
shewn by dotted outline at a Fig. 1, so that where more convenient, the apparatus
may be suspended above the burner A instead of resting thereon as described,
but in either case the chamber D would be provided at its lowest end with any
number of holes or perforations or a space of wire gauze such as 6 Figs. 1 and 4,
through which the now partly cooled products of combustion may pass when driven
against the inner face of D by the greater pressure of the more highly heated air
passing up through the aperture E.
In Figs. 4 and 5 I illustrate the manner in which I construct my invention
when intended for use as a geyser or means for heating water for bath and other
uses, by the heat given off from an ordinary gas burner or burners or oil lamp
or lamps or the lamp of an oil stove.
In this arrangement the chamber D is preferably enclosed by a lid covered
metallic casing J, standing upon feet K, so as to provide space for the gas or
oil burner A and a globe C thereon if required. The chamber D is suspended
within by the means of projections L thereon, resting upon lugs M on the
casing J.
Within the lower, and in this case open end of the chamber D, I provide and
fix a coil or ring N, of copper or other tubing, connected with a tap governed
cold water supply at O, and connected to and communicating with the interior
of the said coil or ring N are any number of copper or other tubes H¹, which
pass through and are connected air-tight with a like number of holes in the
roof D', the upper ends of all the tubes H being bent over towards the centre
of the said roof.
In this arrangement the heat from the burner A by passing up inside the
tubular coil N, into the chamber D, would so heat the tubes H₁ that the heated
water therein would rise and trickle out of the upper ends of same on to the
already heated roof D¹, from the outer edges of which it would trickle down in the
direction of the arrows into an already heated annular trough P, provided upon
the inner face of the casing J the said trough being provided with an open
nozzle R, by means of which the water in P may be withdrawn, as heated.
From the foregoing it will be understood, that the water first becomes heated
in the coil N, and further heated by the hot tubes H¹ in which it rises, and from
which it is delivered on to the heated roof D¹, from which it falls into the already
heated trough P, the water-thereby exuding from the nozzle R almost in a boiling
condition.
I may find it convenient to provide in the lid or cover S of the casing J a hole
or chimney, as suggested by dotted outline at T, so that a cover may be placed
thereon, and removed at will, should the water exuding from R be found to bo
getting too hot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
(1) The herein described apparatus for heating the air in rooms and the like
by the otherwise waste heat of a gas burner used for illuminating purposes, sub-
stantially as herein set forth and shewn.
(2) In an apparatus for heating air by the waste heat of an illuminating gas
burner, the combination of a frame such as B, adapted to be mounted upon a
burner A, and receive a globe such as C, for heating a chamber such as D, sus-
pended above or resting upon the frame B, and provided with a ventilating surface
such as b, and having a cover D₁ and bottom D², the latter having therein an
aperture E, with any number of tubular passages such as Hextending from D2 to 1)¹

page_text: substantially as and for the purposes stated and shewn by Figs. 1, 2, and 3 of the
appended drawings.
.
(3) In an apparatus for heating water by the flame of a gas or oil burner or
burners the combination of a casing J, with closed or open cover S, and supporting.
a chamber such as I) with air tight canopy D¹, the lower end of the said chamber
supporting a tubular coil or ring N in connection with a water supply at O, and
any number of vertical tubular passages such as H' extending upwards through 1)¹,
the upper ends of the said tubes H₁, being then curved towards D', so that the
heated water therein may fall upon D', and from this into an annular trough P,
-provided with an open nozzle R, substantially as and for the purposes stated and
shewn by Figs. 4 and 5 of the appended drawings.
