PROVISIONAL SPECIFICATION.
Improved Apparatus for Heating Apartments, Churches, Chapels,
Cabins, Railway Carriages, and other Places wherein Heat is
Desired.
I JOHN LANGFIELD of Market Square Tyldesley in the County of Lancaster
Engineer do hereby declare the nature of this invention to be as follows:-
This invention is intended to overcome the objection to ordinary heating apparatus
(which sends heated air into a room or other place) which is that the hot air
supplied is too dry, or not pure.
My improved apparatus is constructed as follows:-
Beneath the floor of the apartment to be heated I place a pipe or metal tube
say of about 18 inches diameter and 6 feet long inside a flue or cavity leading from
One end of
a fire or furnace, and by preference sloping upwards from the fire.
this tube is open to the atmosphere or outside air and the other near to the hot
air supply passages.
Inside this tube, and just above the fire or furnace I fix vertically or nearly so a
pipe of about two and a quarter inches diameter and fourteen inches high closed
at both ends; the lower end of this vertical pipe communicates by a small pipe of
about one quarter of an inch diameter with a cistern which supplies water to the
said vertical pipe and by preference maintains the level thereof at a suitable height.
A small pipe is connected to the upper part of the vertical pipe and is carried
along the large metal tube into the cavity connected to the air supply passages to
distribute the air as required to the apartment.
The level of the water in the vertical pipe above named should not rise sufficiently
high to allow the water to escape from the end of the small pipe at the top thereof;
therefore the supply cistern should be provided with a suitable ball-cock or equi-
valent apparatus or if filled by hand should be shallow or made with an overflow
to prevent overfilling of the said vertical pipe.
The action of the apparatus is as follows:-
When the fire is lighted the air in the large tube or pipe is heated and supplied
to the apartment but as soon as it becomes over heated and desiccated the said
tube or pipe becomes red hot and boils the water in the vertical pipe.
Steam is then ejected from the end of the small escape pipe before named which
moistens the air as it is being supplied to the apartment and increases the draught
in the tube.
Thus pure warm and moist air is supplied to the apartment by a simple apparatus
which will require no other attention than that necessary for the fire or furnace
and (when the supply cistern is filled by hand) there are no taps or valves to get
out of order.
I would remark in conclusion that the dimensions given above are only by way
of illustration and may of course be varied to suit different requirements.

Desired.
1 JOHN LANGFIELD of Market Square Tyldesley in the County of Lancaster
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 is intended to overcome the objection to ordinary heating apparatus
(which send sheated air into a room or other place) which is, that the hot air so supplied
is too dry and not pure.
My improved apparatus is designed for the supply of moist heated air which I
propose to effect automatically by means of a jet of steam which mingling with the
heated air before it enters the apartment imparts a sufficient amount of moisture
without lowering the temperature thereof.
The nature of my said invention and the manner in which the same is to be
performed or carried into practica! will be readily understood on reference to the
accompanying sheet of drawings and the following explanation thereof.
Fig. 1. on the drawings is a longitudinal section illustrating one method of applying
my invention and Fig. 2. is a similar view showing a modification thereof.
Referring to Fig. 1.-a is a pipe or metal tube placed beneath the floor of the
apartment or other place to be heated inside a flue or cavity leading from the fire or
furnace e and preferably sloping upwards therefrom.
One end a of this tube is open to the atmosphere or outside air and the other end
leads to the hot air supply passages for heating the apartment.
Inside this tube and preferably just above the fire or furnace e is fixed vertically or
nearly so, a tube d closed at both ends, and the lower end of this vertical tube com-
municates by means of a small reversed syphon pipe e with an open cistern which
thereby supplies water to the said vertical tube, and by preference maintains the level
thereof at a suitable height. The use of the reversed syphon pipe e is to obtain a
column of water of sufficient weight to prevent the steam from forcing the water back
into the cistern.
A spherical or other shaped closed boiler or steam generator may be substituted for
the tube d.
A small pipe g is connected to the upper part of the tube or boiler d and is carried
along inside the larger pipe or metal tube a into the cavity connected with the air
supply passages which distribute the air as required into the apartment or other place
to be heated, the end of the small pipe g being open and provided with a small nozzle
or rose for the issue of the steam.
The level of the water in the tube or boiler d should not rise sufficiently high to
allow the water to escape from the end of the small pipe g at the upper part thereof,
and for this purpose the supply cistern should be provided with a suitable ball cock
or equivalent apparatus or if filled by hand should be shallow and made with an
overflow pipe to prevent over filling of the said tube d.
The action of this apparatus is as follows: When the fire c is lighted the air in
the large tube or pipe a is heated and supplied to the apartment as is the case with
an ordinary hot air stove, but as the air becomes over heated and desiccated it raises
the temperature of the water in the tube or boiler d to boiling heat.
Steam is then ejected from the open end of the small escape pipe g which moistens
the heated air as it is being supplied to the apartment without decreasing the
teinperature thereof and at the same time increases the draught in the said tube.
In the modification shown at Fig. 2 the action is the same but the details of
construction are slightly varied.
Vertical tubes open at each end are substituted for the sloping nina ď

page_text: These tubes are open to the atmosphere at the bottom, and at the top they lead into
the hot air cavity communicating with the hot air passages which supply the air to
the apartment.
The heat from the furnace c acts upon the outside of the tubes has it passes between
them to the chimney or flue and one or more of these pipes (preferably of those
nearest the furnace) has placed inside it a tube, similar to that marked d in Fig. 1,
or other boiler or steam generator to the upper part of which is connected the
small steam pipe g which (when the heat is excessive and the water boils) throws
off steam and supplies moisture to the heated air as in the previous case; is the
supply cistern and the reversed syphon pipe as before.
I would remark in conclusion that the form and position of the air heating
apparatus and the boiler or steam generator may be varied to a considerable extent
and the dimensions of the same and the details of construction altered to meet
different requirements, so long as the principal novel feature of my invention is
retained which is the means described of automatically supplying to the dry heated
air a jet of steam which moistens the same, and replaces the oxygen which was
naturally lost in the heating process thus not only moistening the heated air supplied
but also rendering it pure healthy and agreeable.
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 :-
The combination substantially as hereinbefore described, with a hot air stove, of
a water tube, boiler, or steam generator, placed in the hot air tube or cavity near
to the furnace or fire the water in such tube boiler or generator being supplied
from a cistern and kept automatically at a suitable level, so that when the air in
the said tube or cavity becomes over heated the water boils and distributes a jet
of steam into the hot air cavity so as to moisten the heated air before it is dis-
tributed into the apartment or other place to be warmed.
