mongers, do hereby declare the nature of this invention to be as follows:-
This invention has for object, improved means and apparatus for utilizing the
waste heat from ordinary domestic, or other fire stoves for the purpose of warming
and ventilating rooms or apartments other than those in which such stoves are
situate.
For the purpose of our invention, we erect a tubular or other shaped flue above
or in connection with an ordinary domestic or other fire stove, said flue being within
a chamber in which air has free passage from a lower inlet to an upper outlet from
which it escapes into one or more rooms or apartments situate above the room or
apartment in which the fire stove for giving the heat is arranged or fixed. The
flue tube which heats or warms the ascending air in the space between the flue and
the walls of the chamber, can be stopped at any distance up the house for the
escape of the warmed air into the room directly over, or into a
apartment at a higher level, or the flue tube may be carried to such a height that
more than one upper room can be provided with an outlet, which may be at the
lower part of the upper room for circulation in conjunction with other outlets for
ventilation.
room or
The outlets for the warm air can be provided with shutter or other valves
capable of regulating the quantity of warm air, that has to pass into the upper
apartment.
Supposing a bedroom over a parlour had to be warmed and ventilated-the flue
tube from the lower fire grate could terminate about level with the joists or skirting
board of the bedroom, or where the air outlet is arranged, by a conical or other
flange plate set into the brickwork of what would be the ordinary chimney, which
by our invention forms the continuation of the flue.
The position of the air outlet will necessarily follow upon the particular con-
struction or arrangement of the ordinary chimney especially in houses already
built to which our invention is equally applicable as to houses in progress.

Improved Means and Apparatus for Utilizing the Waste Heat from
Ordinary Domestic or other Fire Stoves for the purpose of
Warming and Ventilating Rooms or Apartments other than those
in which such Stoves are Situate.
We, WILLIAM PRYOR, and CHARLES JAMES MACINTOSH, trading as
Wm. Pryor & Co., of 3 Kingsland High Street, Middlesex, Wholesale Iron-
mongers, do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement :—
This invention has for object, improved means aud apparatus for utilizing the
waste heat from ordinary domestic, or other fire stoves for the purpose of warming
and ventilating rooms or apartments other than those in which such stoves are
situate.
For the purpose of our invention, we erect a tubular, or other shaped smoke
flue in connection with and within the chimney of an ordinary domestic, or other
fire stove. The smoke flue tube which heats the air ascending between it and the
chimney, within which it is placed, can be stopped at any distance up the chimney
for the escape of the warmed air into the room directly over, or into a room or
apartment at a higher level, or the smoke flue tube may be carried to such a height
that more than one upper room can be provided with an outlet, which may be at
the lower part of either, or all of the upper rooms for the purpose of introducing
into such room or rooms a supply of fresh air warmed, or otherwise, such fresh air
being by preference drawn from outside of house or building.
The outlets for the fresh air warmed, or otherwise, can be provided with shutters,
or other valves capable of regulating the quantity of warm, or other fresh air that
it may be wished to pass into either or all of the upper apartments.
Supposing a bedroom over a parlour had to be warned and ventilated, the smoke
flue tube from the lower fire grate could terminate a short distance above the level
of skirting board of the bedroom, or where the air outlet is arranged by a flange,
conical, or other plate set into the brickwork.
The position of the air outlet will necessarily follow upon the particular con-
struction, or arrangement of the ordinary chimney, especially in houses already
built, to which our invention is equally applicable as to houses in progress.
Our invention will be more particularly understood by the annexed drawings.
Figure 1 is an elevation of portions of two rooms, one above the other.
Figure 2 represents a section of a portion of a house with the fresh air inlet,
behind the stove but the air may enter at any convenient position.
A is the ordinary fireplace. B an ordinary chimney. Ca smoke flue tube
fitted therein. Da branch of the chimney leading to an air inlet valve E. The
smoke flue tube C terminates just above the outlet valve G by a funnel shaped
enlargement. The valve G may have a shutter for partially or entirely closing it,
whereby any air, warm or otherwise, in the chamber formed between smoke flue
and chimney proper will be controlled in, or altogether prevented from entering
the upper room.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. The improved means and apparatus for utilizing the waste heat from ordinary
domestic, or other fire stoves for the purpose of warming and ventilating rooms or
apartments other than those in which such stoves are situate, as hereinbefore
described and substantially as shown by the annexed drawings.
2. Placing a smoke flue tube in an ordinary chimney, and utilizing the space
between the chimney proper and such smoke flue tube for the passage of fresh air
for the purpose of warming and ventilating an upper room or rooms by heat
derived from a fire below, as set forth, and also providing means whereby a supply
of fresh air drawn by preference from outside house or building can be introduced
into such room or rooms when heat is not required.
