I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention refers to a method of heating a suite of communicating apartments
in a simple, effective and economical manner.
This method is economical because with a single stove or other heating apparatus a
whole suite of communicating apartments can be heated without pipes or other
expensive apparatus passing from one room to the other as is the case with hot air,
water or steam installations.
In the apartments as ordinarily arranged the stove is placed in one of the rooms and
will heat this room, the highest temperature being against the ceiling and the lowest
on the floor so that the room is so to say divided into horizontal strata of air of
different temperature. If this stove is to heat the whole suite of rooms the doors will
be opened but in spite of this the heating of the other apartments will be insufficient,
because the warmest air which can pass into the next room will be of the temperatura
of the stratum of air horizontal with the top of the door; this temperature will be the
warmest in the second room and it will be seen thus that by the time it reaches the
last room the temperature there will be lower than the lowest in the first room.
By a simple but effective arrangement this can be avoided and a uniform
temperature maintained throughout the whole suite with one stove only. This
arrangement consists essentially in providing in the walls or partitions between the
rooms convenient openings against the ceiling, or even through the ceiling itself.
Through these openings the air of the highest temperature i.e. that against the ceiling
will circulate through the whole of the rooms and when cooled will descend to the
height of the doors and pass back through the doors into the room containing the
stove to be warmed again ascend to the ceiling and pass again through the rooms.
This system of circulation will ensure a uniform and economical heating of all the
communicating rooms, no matter into which the stove or heating apparatus is placed.

small or unsightly stove be used it is immaterial with the application of this arrange-
ment into which room it is placed and can therefore be put up where it is least seen or
where it is least in the way, and to obtain a larger heating surface and consequently a
larger amount of warm air it is preferable to curve the stove pipe several times against
the wall at different heights. If an existing stove in one of the rooms is to be used it
can be converted into a great heat generator in the following manner :-The stove
will be of cast iron and will be deeply fluted or grooved to increase the heating
surface. The doors will be generally closed to force all the air drawn in by the draught
across the fire to heat the stove pipes. The latter will be of cast iron and enclosed in
a barrel or case through which the air of the room passes through openings in the
bottom and passes out hot through openings in the top to warm the room and to pass
also through the other rooms in consequence of the above described arrangement.

page_text: I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. 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 refers to a method of heating a suite of communicating apartments
in a simple effective and economical manner.
This method is economical because with a single stove or other heating apparatus
a whole suite of communicating apartments can be heated without .pipes or other
expensive apparatus passing from one room to the other as is the case with hot air,
water or steam installations.
In the accompanying drawings Figure 1 represents a suite of apartments where the
present invention is not employed and Figure 2 represents the same with the
application of the invention a single stove or other heating apparatus B being
sufficient to heat the whole suite. Figure 3 is a modification.
If
In the apartments as ordinarily arranged the stove B is placed in one of the rooms
for instance in A. and will heat this room the highest temperature being against the
ceiling E and the lowest on the floor so that the room is so to say divided into
horizontal strata of air of different temperatures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 etc.
this stove is to heat the whole suite of rooms A D L M and N, the doors, Ć G J and K
will be opened but in spite of this the heating of the other apartments will be in-
sufficient because the warmest air which can pass into the next room will be of the
temperature of the stratum of air horizontal with the top of the door; in Figure 1
No. 5 in room A this temperature will be the warmest in the second room and it will
be seen thus that by the time it reaches the last room the temperature there will be
lower than the lowest in the first room.
By a simple but effective arrangement this can be avoided and a uniform
temperature maintained throughout the whole suite with one stove only. This
arrangement consists essentially in providing in the walls or partitions between the
rooms convenient openings against the ceiling see O Figure 2 or even through the
ceiling itself see Figure 3; through these openings the air of the highest
temperature i.e. that against the ceiling will circulate through the whole of the
rooms A D L M and N and when cooled will descend to the height of the doors and
pass back through the doors into the room containing the stove to be warmed again
ascend to the ceiling and pass again through the rooms. This system of circulation
will ensure a uniform and economical heating of all the communicating rooms, no
matter into which the stove or heating apparatus is placed.

page_text: Regarding the placing and use of the stoves it is as well to say a few words. If a
small or unsightly stove be used it is immaterial with the application of this arrange-
ment into which room it is placed and can therefore be put up where it is least seen or
where it is least in the way and to obtain a larger heating surface and consequently
a larger amount of warm air it is preferable to curve the stove pipe several times
against the wall at different heights. If an existing stove in one of the rooms is to he
used it can be converted into a great heat generator in the following manner-The
stove will be of cast iron and will be deeply fluted or grooved to increase the heating
surface. The doors will be generally closed to force all the air drawn in by the
draught across the fire to heat the stove pipes. The latter will be of cast iron and
enclosed in a barrel or case through which the air of the room passes through openings
in the bottom and passes out hot through openings in the top to warm the room
and to pass also through the other rooms in consequence of the above described
arrangement.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
The method of warming a suite of apartments by means of openings so arranged
that the upper or heated atmospheric strata heated in the first apartment can pass
through the entire suite to the last apartment substantially as specified.
