PROVISIONAL SPECIFICATION.
Improved System of and Apparatus for Warming and Ventilating
Buildings.
I, JAMES BARTLETT of Buckingham House, Finsbury Park in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved system of and apparatus for warming and
ventilating buildings by means of which the veutilation is continuous and a
constant supply of fresh clean air can be passed through a building at whatever
temperature may be desired. It is sometimes desirable and very often necessary
that different rooms should have different temperatures and also that the tempera-
ture should be under the control of the occupants of each room. The double duct
method hereinafter described fulfils all these requirements.
In carrying the invention into effect, I provide a heating chamber in which the
air, after first passing through the air inlet, is warmed by contact with surfaces
heated either by steam, hot water, or direct fire. Fans are placed at the entrance
to ducts, one for forcing warm air into the upper horizontal duct and the other for
forcing cold air into the lower duct. A horizontal duct or channel formed double
runs the entire length of the building to be warmed or ventilated. Leading
from this double duct are vertical flues arranged in the walls and leading to the
various rooms in the building. A valve is placed at the base of each vertical flue
controlled from the room above by means of a chain over a pulley or any other
suitable device. If the valve be dropped to its lowest position, warm air only will
be admitted into the room; if raised to its highest position, cold air only, and if
placed in an intermediate position, both warm and cold air will be admitted, the
amount of each being regulated by means of any suitable indicator or handle. Any
desired temperature can thus be secured for a room, independently of any other
room in the building and without reducing the total volume. The upper duct might
be used for warm air and the lower duct for cold air, but these can be reversed
without making much practical difference. The double duct can be arranged at
the top of a corridor or other convenient place as well as below a corridor or other
part of the building.

Improved System of and Apparatus for Warming and Ventilating
Buildings.
I, JAMES BARTLETT, of Buckingham House, Finsbury Park in the County of
Middlesex Engineer, 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 an improved system of and apparatus for warming and

may be desired. It is sometimes desirable and very often necessary that different

page_text: under the control of the occupants of each room. The double duct method herein-
after described fulfils all these requirements.
The invention will be understood by referring to the accompanying drawings, in
which,
Figure 1 is a vertical section on the line y y of Figure 2;
Figure 2 a horizontal section on the line of Figure 1; and
Figure 3 a vertical section on the line z z of Figure 1.
In these figures-
A, is a heating chamber in which the air, after first passing through the air
inlet a, is warmed by contact with surfaces heated either by steam, hot water or direct
fire. The drawing shows it passing through heated tubes B. C is the engine room
in which is located preferably a gas engine to drive the Blackman fans D placed at
the entrance to each duct e and e¹, one for forcing warm air into the upper horizontal
ducte and the other for forcing cold air into the lower duct e¹. E is a horizontal
duct or channel formed double as shown in Figure 3 and which runs the entire
length of the, building to be warmed or ventilated. Leading from this double
duct e c', are vertical flues F arranged in the walls and leading to the various rooms
in the building. A valve G is placed at the base of each vertical flue controlled
from the room above by means of a chain over a pulley or any other suitable
device. If the valve G be dropped to its lowest position, warm air only will be
admitted into the room; if raised to its highest position, cold air only; and, if
placed in an intermediate position, both warm and cold air will be admitted, the
amount of each being regulated by means of any suitable indicator or handle.
Any desired temperature can thus be secured for a room, independently of any
other room in the building and without reducing the total volume. The drawings
show the upper duct e for warm air and the lower duct e' for cold air, but these can
be reversed without making much practical difference. The double duct e e¹ can be
arranged at the top of a corridor or other convenient place as well as below a
corridor or any other part of the building.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The improved system of warming and ventilating buildings consisting of a
horizontal or inclined channel or duct formed in two parts, one for the passage of
warm air and the other for the passage of cold air, and ascending flues arranged
in the walls to convey the air from said ducts to different parts of the building,
substantially as and for the purpose described.
2. The combination of the heating chamber and hot. ir flue with a cold air flue
and independent fan for forcing the air through each tube with means for regulating
the quantity of each variety of air entering through a common flue into the room,
substantially as and for the purposes described.
3. The apparatus for warming and ventilating buildings, substantially as and for
the purposes described.
