Middlesex for an Invention of "IMPROVEMENTS IN STOVES OR APPARATUS
FOR WARMING AIR FOR HEATING APARTMENTS AND BUILDINGS OR OTHER
PLACES"
PROVISIONAL SPECIFICATION left by the said Henry Darby at the Office
of the Commissioners of Patents on the 4th December 1883.
HENRY DARBY of Caledonian Road in the County of Middlesex, " IMPROVE-
MENTS IN STOVES OR APPARATUS FOR WARMING AIR FOR HEATING APARTMENTS
AND BUILDINGS OR OTHER PLACES
"
This invention relates to improvements in stoves or apparatus for warming air
for heating apartments buildings or other places in which the products of
combustion from a lamp gas burner stove or other source of combustion and heat
are received or conducted into a tube or chamber (or a series of tubes or chambers)
the heat and products of combustion after circulating therein being allowed to
escape slowly therefrom the watery vapor as it condences falling or passing into a
receptacle arranged to receive it.
According to one form or arrangement of apparatus constructed and acting in
accordance with my improvements I construct two vertical tubes passages or
chambers which may form hollow standards for carrying and supporting the stove.
These hollow standards are connected by two (or more) horizontal tubes passages
or chambers into the lowest of which (divided by a stop or partition) the chimney
of a lamp or gas burner (or the flue of a stove or other source of heat or combustion)
enters.
The heat and products of combustion enter the horizontal tube on each side of
the partition one portion of the heat passing up the vertical hollow standard at
one end thence through the horizontal tube passage or chamber (or chambers) and
down the hollow standard at the other end escaping by a suitable, outlet or outlets
at the bottom where a receptacle is arranged to receive the condensed vapour.

page_text: The other part or half of the products of combustion pass in the opposite
direction along the horizontal tube and down the hollow standard to the outlet and
receptacle for condenced vapour.
The bottom of each hollow standard is formed with corresponding outlets and
receptacles for receiving the condenced vapour but in action atmospheric air enters
into and ascends up one of the hollow standards being heated in its passage to the
other hollow standard by which it descends and passes to the outlet below.
Some-times one hollow standard acts as the air inlet and sometimes the other
according to the temperature or position of the apparatus
Chambers for heating water may be arranged in combination with the heating
tubes and an open vessel containing water is combined with the apparatus the form
and arrangement of which may be considerably varied
The circulating tubes or passages may be inclined in place of horizontal if
desired
Radiating plates or surfaces may be arranged in combination with the stove if
desired

HENRY DARBY of Caledonian Road in the County of Middlesex "IMPROVE-

This invention relates to improvements in stoves or apparatus for warming air

are received or conducted into a tube or chamber (or a series of tubes or chambers)
the heat and products of combustion after circulating therein being allowed to

These hollow standards are connected by two (or more) horizontal tubes passages
or chambers into the lowest of which (divided by a stop or partition) the chimney

enters.
The heat and products of combustion enter the horizontal tube on each side of
the partition one portion of the heat passing up the vertical hollow standard at

The other part or half of the products of combustion pass in the opposite
direction along the horizontal tube and down the hollow standard to the outlet
and receptacle for condensed vapour.
The bottom of each hollow standard is formed with corresponding outlets and
receptacles for receiving the condensed vapour but in action atmospheric air enters
into and ascends up one of the hollow standards being heated in its passage to the
other hollow standard by which it descends and passes to the outlet below.
Sometimes one hollow standard acts as the air inlet and sometimes the other
according to the temperature or position of the apparatus.
Chambers for heating water may be arranged in combination with the heating
tubes and an open vessel containing water is combined with the apparatus the
form and arrangement of which may be considerably varied.
The circulating tubes or passages may be inclined in place of horizontal if
desired.
Radiating plates or surfaces may be arranged in combination with the stove if
desired.
And in order that my invention may be clearly understood and readily carried
into practice I will now describe the Drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS
1
Figure 1 is a side elevation, Figure 2 an end view, Figure 3 is a longitudinal
section and Figure 4 a transverse section of a stove or apparatus for warming air
for heating apartments and buildings or other places arranged and constructed in
accordance with my improvements.

a. a. are the end vertical tubes passages or chambers which form hollow standards
for carrying and supporting the stove. a¹. a. are horizontal tubes passages or
chambers which connect the vertical passages a. a. together the lower passage being
divided by a stop or partition a².
a. a. are air tubes open at each end as shown.
The lower ends of the vertical passages a. a. are connected by a pan or
receptacle a for receiving the condensed vapour.
b is an ordinary lamp (advantageously for burning petroleum or other cheap
oil or spirit) the heat and products of combustion from which pass up into the
lower horizontal passage a part of the heat passing to the right and part to the
left of the partition a² and circulating in the passages a and a¹ as previously
'described.
:
a. are outlets through which the condensed vapour flows into the pan or
receptacle a*.
Having thus described the nature of my invention and the manner of performing
or carrying the same into practice it should be clearly understood that I make no
claim to any of the parts separately which are well known and in common use-
But what I claim is:-
The improved arrangement and construction of stoves or apparatus for warming
air for heating apartments buildings and other places such apparatus acting
substantially as and for the purpose herein before fully described.
In witness whereof I the said Henry Darby have hereunto set my hand and
seal this Thirty first day of May in the year of our Lord One thousand eight
hundred and eighty four.
