A New or Improved Heating or Radiating Appliance for use in
connection with Domestic Fire Places.
We, GEORGE MIDDLETON, Photographer, 17 Clarendon Terrace, Laygate
Lane, and ROBERT DAVISON, Blacksmith, 158 South Frederick Street, both in
South Shields in the County of Durham 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 :-
This invention relates to a new or improved heating or radiating appliance for
use in connection with domestic fire places.
As is well known a very large proportion of the heat evolved from the fuel in
ordinary fire places is wasted and our object is to devise an appliance which will
tend to concentrate and distribute the heat into the room and thus economise fuel.
For this purpose we make use of a hollow receptacle constructed by preference
of some good conductor of heat and in order to afford access to the interior of the
receptacle we pierce its walls with holes.
We find that the gases evolved from the burning fuel are in this manner attracted
to the receptacle and as the latter is heated in the fire to a red or white heat the
gases are burnt therein thus effecting in a concentrated space an intense heat. We
find that such an appliance placed in the grate of an ordinary fireplace has the
effect of increasing the temperature of the room considerably above the temperature
obtained from fuel burnt in grates of the ordinary description while at the same
time economy in quantity of fuel used accrues.
We will fully describe our invention with reference to the accompanying drawings
in which
Figure 1 shows an elevation.
Figure 2 a plan view and
Figure 3 a sectional elevation of a receptacle such as that hereinabove referred
to and throughout this description like marks of reference indicate like parts.
Referring to the figures, A is a perforated receptacle constructed of cast iron,
though wrought iron or other equivalent material will answer the purpose. We
prefer to construct it with slightly tapering sides as shown, with legs or feet A'
for it to stand on, with an internal perforated plate or grate A³, and with a
perforated crown or lid A³.
To apply it place the receptacle in the centre of an ordinary fire grate and
arrange the fuel around it.
After the fuel has burnt for a while the

receptacle turns red hot and becomes a
Some of these gases enter the perfora-
walls of the receptacle or as they issue
The incandescent state of the receptacle and the additional heat evolved from
the increased quantity of burnt gases has the effect as regards the chamber in
which it is applied above described.
When the fire requires more fuel it must be placed around the receptacle A or
a little fuel may be added within the same by the opening of the lid A³ when the
receptacle will continue to perform its heating and radiating functions.
For culinary purposes the lid A3 will be found to be a useful adjunct for which
purpose we prefer to construct it with a flat top but a domed top may be used
where greater neatness is desired.

tion, and in what manner the same is to be performed, we declare that what we
claim is :
A perforated receptacle constructed and adapted to operate substantially in the
manner and for the purposes herein set forth.
