Improvements in Heating and Ventilating and Cooling and
Ventilating Public Buildings, Hospitals, Dwelling Houses,
Ships, Conservatories, and other Places.
I, ROBERT BELL, of 29 Lynedoch Street, Glasgow, in the County of Lanark,
North Britain, Doctor of Medicine and a Fellow of the Faculty of Physicians
and Surgeons, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in heating and ventilating, and cooling
and ventilating, public-buildings, hospitals, dwelling houses, ships, conservatories
and other places requiring to be supplied with hot fresh air, or cold fresh air, as
the case may be and consists as follows:-
:-
In carrying out my invention as applied for heating and ventilating buildings
and the like, I employ an air shaft, the one end of which is in direct communica-
tion with the outer atmosphere, and if desired it may be provided with a dust or
other guard. The said air shaft is connected to a pump or the like so as to propel
fresh air into the various compartments of the building or the like in a continuous
stream, there being branch pipes, or air shafts, provided for each compartment, and
if desired one or all of the said branch pipes and air shaft may be provided with
suitable regulating cocks or valves. In order to heat the air during its passage
through the air shaft I mount within the same a suitable steam pipe which is
supplied with steam from any convenient source, and if desired branch steam
pipes may be mounted in one or more or all of the branch air pipes or shafts; the
said branch air shafts being provided with suitable means for diffusing the heated
air throughout the various compartments.
In carrying out my said invention as applied for cooling and ventilating buildings
and the like, I employ the same arrangement of apparatus as for heating and
ventilating, but in lieu of passing steam through the pipes contained in the air
shaft or shafts, I pass a stream of cooled brine. The said brine is reduced to a
low temperature and circulated through the said pipe or pipes by any suitable
means so as to cool the air passing through the air shalt or shafts.
As a modification in lieu of employing a steam pipe or pipes for heating the air
in the shaft or shafts I may pass the air shaft or shafts through one or more
suitable furnaces so as to make the air shaft or shafts the heat conveyer or
conveyers.
In carrying out my invention as applied to ships and the like 1 provide one or
more of the ventilating shafts with steam pipes, preferably formed as coils and
suitably attached within the ventilator shafts in such a manner as to heat the air
passing to the stockholds, saloons, cabins and the like. The said pipes or coils may
also be used for cooling the air by means of circulating a stream of brine, cooled
to a low temperature through them, in such a manner, as that on the air passing
down through the ventilating shafts, coming into contact with the said pipes or
coils, it, the air, is deprived of its caloric, and thus cold fresh air is supplied to the
stokeholds, saloons, cabins, and the like.

page_text: The whole arrangement provides efficient means for heating and ventilating or
cooling and ventilating, public buildings, hospitals, dwelling houses, ships, conser-
vatories and other places.

Improvements in Heating and Ventilating and Cooling and
Ventilating Public Buildings, Hospitals, Dwelling Houses,
Ships, Conservatories, and other Places.
I, ROBERT BELL, of 29 Lynedoch Street, Glasgow, in the County of Lanark,
North Britain, Doctor of Medicine and a Fellow of the Faculty of Physicians
and Surgeons, 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 improvements in heating and ventilating, and cooling
and ventilating public buildings, hospitals, dwelling houses, ships, conservatories
and other places requiring to be supplied with hot fresh air, or cold fresh air,
as the case may be and consists as follows:-
In carrying out my invention as applied for heating and ventilating buildings
and the like and as is illustrated in the annexed sectional drawing I employ an air
shaft or shafts A, the one end a of which is in direct communication with the
outer atmosphere and if desired it may be provided with a dust or other guard a¹.
The said air shaft is connected to a fan pump or the like B so as to propel fresh
air into the various compartments of the building or the like in a continuous stream,
there being branch pipes or air shafts A' provided for each compartment, and if
desired one or all of the said branch pipes and air shaft may be provided with
suitable regulating cocks or valves. In order to heat the air during its passage
through the air shaft or shafts A, I mount within the same a suitable steam pipe
or pipes C, which is or are supplied with steam or hot water from any convenient
source, and if desired branch steam or hot water pipes B' may be mounted in one
or more or all of the branch air pipes or shafts A'; the said branch air shafts
being provided with suitable means such as with perforations D for diffusing the
heated air derived from the radiation of heat from the hot pipes B', throughout
the various compartments, the said steam or hot water pipes B being so arranged
as to form means whereby a continuous circulation of the heating agency is
effected.
In some cases if desired I may employ in lieu of the propelling fan, pump or
the like an outside cowl E so constructed and arranged as to have its opening
always facing the wind; said cowl E being mounted on the top end of a vertical
air supply shaft or pipe F which may pass down the chimneys or interior of the
building, as shown, though it may also be arranged outside the building.
In some cases, such as for hospitals and the like, where it is desired to purify the
air before it is heated or passed into the air shaft or shafts I may pass the air over
iron bars or pipes heated to a red heat by any suitable means so as to free it from
all impurities.
In carrying out my said invention as applied for cooling and ventilating
buildings and the like, I employ the same arrangement of apparatus as for heating
and ventilating, but in lieu of passing steam or hot water through the pipes con-
tained in the air shaft or shafts, I pass a stream of cold water or cooled brine
according to the degree of cold required, the said brine is reduced to a low

page_text: temperature and circulated through the said pipe or pipes by any suitable means
so as to cool the air passing through the air shaft or shafts.
As a modification in lieu of employing hot water or steam pipe or pipes for
heating the air in the shaft or shafts I may pass the air shaft or shafts through one
or more suitable furnaces so as to make the air shaft or shafts the heat conveyer
or conveyers.
In carrying out my invention as applied to ships and the like I provide one or
more of the ventilating shafts with steam pipes, preferably formed as coils and
suitably attached within the ventilator shafts, in such a manner as to heat the air
passing to the stockholds, saloons, cabins and the like. The said pipes or coils
may also be used for cooling the air by means of circulating a stream of brine,
cooled to a low temperature or a stream of cold or iced water as required through
them, in such a manner, that on the air passing down through the ventilating shafts,
coming into contact with the said pipes or coils, it, the air, is deprived of its
caloric to a greater or less effect, and thus cooled fresh air is supplied to the
stokeholds, saloons cabins and the like.
The whole arrangement provides efficient means for heating and ventilating or
cooling and ventilating, public buildings, hospitals, dwelling-houses, ships, conser-
vatories and other places.
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 :-
1st. The general arrangement, construction and combination of the various parts
constituting my improvements in heating and ventilating and cooling and ventilating
public buildings, hospitals, dwelling-houses, ships, conservatories, and other places,
substantially as herein before described and shown in the accompanying drawings.
2nd. The improved means whereby fresh atmospheric air in a heated condition
is supplied to buildings, and other places, substantially as herein-before described
and shown in the accompanying drawings.
3rd. The improved means whereby fresh atmospheric air in a cooled condition
is supplied to buildings and other places, substantially as hereinbefore described
and shown in the accompanying drawings.
