I JOHN DOWN of Hill Side House, Hope Chapel Hill, in the parish of
Clifton, in the city and county of Bristol, Greenhouse and Conservatory Stove
Manufacturer do hereby declare the nature of my said invention to be as
follows
-
This invention relates to a novel construction or arrangement of apparatus
constituting a stove, heated by gas or a lamp by the heat of which a natural flow of
air through a pipe fitted within the flue pipe, is induced which air pipe has a clear
passage from the atmosphere into the greenhouse or apartment, the air being heated
in its passage by conduction, by the escaping fumes or heat passing through the flue,
which enters from a box in which the first heating takes place to an outlet which is
also outside and open to the atmosphere as is also the air supply tube which feeds the
box or stove proper which serves as a generating chamber for the full development of
the heat given off from the flame or flames
The air inlet pipe for the gas stove is of larger diameter than the flue or outlet so
that a full supply of air enters the box the pressure generated within the box and flue
being sufficient to prevent back draught.
I prefer to arrange the inlet pipe horizontal and lead it into the bottom of the
stove box and fit the outlet pipe which acts as a flue, also horizontal, the air heating
tube passing through the same within the flue, which flue may be of such a length
as to project through another wall or into an uptake, or it may return with a tapering
pipe to an outlet through the same wall in which the air supply tube is fitted, the
enlarged outlet having a tee piece or other check.
By making the return flue tapering or of larger diameter from the bend enables
any condensed water to flow away.
Dated this 6th day of June 1888.

I, JOHN DOWN, of Hill Side House, Hope Chapel Hill, in the parish of
Clifton, in the city and county of Bristol, Greenhouse and Conservatory Stove
Manufacturer, 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 novel construction or arrangement of apparatus, such as I
show in the annexed drawing, and constituting a stove A heated by gas, or a lamp,
the heat of which induces a natural flow of air through a pipe B fitted within the flue
pipe C, which air pipe B has a clear passage from the atmosphere into the
Greenhouse or apartment.
The air is heated in its passage through the pipe B by conduction by the escaping
fumes or heat passing through the flue C which enters from the box A in which the
first heating takes place to a return or outlet pipe D which is also outside and open
to the atmosphere, as is also the air supply tube E which feeds the box or stove
proper. This box A and flue Cserve as a generating chamber for the full developement
of the heat given off from the flame or flames.
The air inlet pipe E is of larger diameter than the flue outlet branch F to prevent
back draught.
By making the return flue tapering from the bend G, condensed water may flow
away by the drip nozzle H while the vapour escapes by the end I.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Fitting an open ended pipe B through and within a flue pipe (), for rarifying
inflowing air by the surrounding heat and products of combustion issuing from a
stove A as and for the purposes described.
