page_text: I, WILLIAM PAGET HOBLYN, of the Fir Hill near St. Columb, in the County
of Cornwall Justice of the Peace for the said County, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be.)
. par-
ticularly described and ascertained in and by the following statement :-
The object of my, invention is to provide a simple and effective form of smoke.
consuming furnace.
For this purpose I construct a partition of metal, or fire brick, or other suitable
material near the end of the stove away from the furnace door. It will not be
necessary to continue the fire bars under this partition, but their existence there
will not materially interfere with the carrying out of my plan. A false top is
placed in the upper part of the furnace reaching from the further end of the
furnace nearly to the furnace door. There is a space between this top and the
before mentioned partition. Fresh air enters through the ash pit door, passes up
the passage between the partition and the back of the furnace, is deflected by the
false top, passes along the upper part of the furnace, and emerges by the passage
between the deflecting false top and the door end of the furnace. Or an additional
deflector may be placed under the other, carried beyond the partition, but not
continued to either end of the furnace. A space must also be left between this
second deflector and the partition. In this second form of furnace only a part of
the fresh air rising from the ash pit passes through the furnace beneath the lower
deflector, the other part being carried between the two deflectors or false tops, both
parts however emerging by the passage as before described. With either of these
forms the air in its course is sufficiently heated to consume the whole or nearly the
whole of the smoke emerging from the furnace. The chimney to carry off the
products of combustion may be placed above or nearly above the passage, that is
at the door end of the furnace, or the products of combustion may be conducted
through a flue to a chimney placed in any convenient position.
A simple modification of the apparatus dispenses with the deflecting false tops.
The air rising from the ash pit & passing up the passage between the partition and
the end of the furnace in this case meets the smoke emerging from the stove over
the partition.
In all these forms the furnace bars may be horizontal or sloping upwards from
the door, or partly horizontal and partly inclined upwards.

Having now particularly described and ascertained the nature of my inven-

I claim is
In a furnace or stove the use of the partition with or without the deflecting false
tops, or with the upper deflecting false top as herein described.
