PROVISIONAL SPECIFICATION.
An Improvement in Domestic Fire Ranges or Heaters.
I, JAMES WADE, of Number 72, Albion Street, in the City of Leeds, Solicitor,
do hereby declare the nature of this invention to be as follows:-
My invention is intended to increase the heat of domestic fires for cooking and
other purposes. In so doing I provide a plate or series of plates of metal or
other suitable substance hung on to the bars with clips or catches, each plate
having a series of connical tubes cast or affixed thereto, which project into the
centre of the fire, the wide end of the connical tubes outside, and the smaller
end inside. By this means I say that the amount of air entering the wide end
of the tubes is contracted at the smaller end, causing a natural blast, as the air
must pass into the fire with greater velocity. I also adapt the same means to
set-pots, or coppers.

An Improvement in Domestic Fire Ranges or Heaters.
I, JAMES WADE, of Number 72, Albion Street, in the City of Leeds, Solicitor,
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 is intended to increase the heat of domestic fires for cooking
and other purposes. For the purpose of effecting this, a plate or series of plates
of metal or other suitable substances (in which are one or more holes) with clips
or catches, is hung on to the bars. Each plate has one or more conical tubes
cast or affixed thereon, the smaller ends of which project into or towards the
centre of the fire, the wider end of each tube being on the outside of the fire
and attached to or projecting through the said plate. By this means, I say, that
the amount of air entering the wider end of the tubes is contracted as it passes
towards the smaller ends, causing a natural blast, as the air at that point (the
smaller end) will have an increased velocity according to the size and shape of
the cone.
Referring to the accompanying drawing, "C" (Figures 1 and 3) represents
a flat plate of metal or other suitable substance which is hung on the outside
of the fire bars "E" (Figures 2 and 4) by means of the clips or catch "F"
(Figures 2 and 4), and which plate shuts off a portion of the atmosphere from
the fire. Into the said plate "C" is fixed a series of conical tubes "D"
(Figures 2 and 4) with the larger openings in C and the smaller projecting
between the bars of the fire grate into the fire. These tubes are made round
or rectangular to suit different ranges.
When the "heater" is fixed on the bars adjacent to the oven, with the tubes

page_text: projecting into or towards the centre of the fire, the air passes through the tubes
in the direction shown by the arrows in Figures 2 and 4. As the inner opening
or end is smaller than the outer one, the air passes into the fire at a greater
velocity than when it enters the wider end, the natural draught thus being
concentrated and led to the heart of the fire, keeps the coal or cinders from con-
gealing or getting sad, and better combustion is obtained with less variation of
temperature.
A similar heater is also applied to ordinary household setpots and coppers.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner it is to be used, I declare that I claim:-
The conical tubes or ducts attached to an outside plate for the purposes sub-
stantially as herein before set forth and described.
