PROVISIONAL SPECIFICATION left by the said Walter Brierley at the Office
of the Commissioners of Patents on the 27th February 1883.

* IMPROVEMENTS IN APPARATUS FOR HEATING AIR FOR WARMING, BUILDINGS. AND
OTHER USES" (communicated to me from abroad by Robert Tungler of Goerlitz,
Prussia)
This invention relates to an improved construction of apparatus or furnace to be
employed for heating air for warming buildings and other purposes requiring the
application of hot air, the apparatus being constructed wholly of brick and mason
work except the doors and furnace bars the liability to fracture as where iron and
brick work are used in the composition of a furnace is obviated a great amount of
heat when once the furnace has been fired is stored and available for heating air.
Furnaces or apparatus according to this invention are by preference rectangular
the firing hole being funnel shaped, behind the bridge is a series of upright and of
pendant divisions or partitions there being a second series of such divisions and
cells the whole forming two series of passage way cells through which the air to be
heated circulates thence passes to an inner circulating chamber and through
distributing chambers to its exit.
On being fired the furnace is closed so as to exclude air except by an aperture
below the furnace bars and through air slits formed in the furnace specially
provided the latter air supply being for the purpose of ensuring complete combustion
there being provided doors or valves for regulating the circulation.

WALTER BRIERLEY of Halifax in the County of York, Patent Agent
"IMPROVEMENTS IN APPARATUS FOR HEATING AIR FOR WARMING BUILDINGS AND
OTHER USES communicated to me from abroad by Robert Tungfer of Goerlitz
Germany.
"
This Invention relates to an improved construction of Apparatus or furnace to
be employed for heating Air for warming buildings, and other purposes requiring
the application of hot air, the Apparatus being constructed wholly of brick and
mason work except the doors and furnace bars the liability to fracture as where
iron and brick work are used in the composition of a furnace is obviated a great
amount of heat when once the furnace has been fired is stored and available for
heating Air.
Furnaces or apparatus according to this invention are by preference rectangular
the firing hole being funnel shaped behind the bridge is a series of upright and
of pendant divisions or partitions there being a second series of such divisions &
cells the whole forming two Series of passage way cells through which the air to
be heated circulates thence passes to an inner circulating chamber & through
distributing chambers to its exit.
On being fired the furnace is closed so as to exclude air except by an aperture
below the furnace bars and through Air slits formed in the furnace specially
provided the latter air supply being for the purpose of ensuring complete combustion
there being provided doors or valves for regulating the circulation.
Such being the nature of the said invention the particulars thereof will be fully
understood from the following description aided by the annexed drawings of
which―
Fig. 1 shows a vertical longitudinal Section
Fig. an horizontal longitudinal plan in Section
Fig. 3 a vertical cross-section of the stove with surrounding brickwork.
At A is the furnace the grate after firing the doors are closed the supply of air
for combustion of fuel is by way of door C', A further supply of air can be admitted
by slits. g, g. which can be locked and communicate with a slit 6 surrounding the
hearth the latter supply of air is to ensure the complete consumption of any remaining
products of combustion.
The firegases pass along one side of the stove A advance in a zigzag line between
partition-walls d d d return by the other side betwixt similar partition-walls d d
and pass along the channel h towards the chimney c.
The partition walls d d are constructed of brick work as is the other part of the
stove whereby unequal expansion and defective joints are avoided and by reason
of the quantity of brick work a large amount of heat is stored as at the time the
fuel is in a perfect state of "glowing heat" the brickwork will after closing the.
shutter C¹ be already sufficiently heated for warming the air streaming through for
a considérable time. The firing and heating of the stove itself is therefore to be
effected the night previously.
The stove A is for some distance surrounded by an hull B of brickwork. When,
the air heating is to take place the channels i of admission of cold air are opened.
The cold air will be warmed by streaming over the surface of the stove A and enters
after passing through the distributing channels k k the rooms to be beated.
By shutting the channels facility is given to retain the warmed air, where

page_text: opportunity is afforded the attendant to regulate directly from the stove and from
the air's discharge the entire circulation of the air currents, to such other purposes
(than the heating of rooms) as required.
Having thus fully described the nature and particulars of the said invention I
would have it understood that I claim
The air heating stove A constructed of brick work having partition walls d d. d, d¹
the funnel shaped hearth a in combination with doors c. c. c. and slits g, g, and
substantially as described and for purpose set forth.
In Witness whereof I the said Walter Brierley have hereunto set my hand and
seal this twentieth day of August in the year of our Lord one thousand eight
hundred and eighty three.
