Improvements in Ventilators.
I, ROBERT MACKAY, Junior, Ventilating Engineer, 150, Hope Street, Glasgow,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to house and ship ventilators both for the outlet of the
vitiated air and the inlet of fresh air, and it has for its object to increase the
temperature as may be required of the air entering or leaving the building or
ship. In carrying out my invention I make use of an electric current to heat the
air in the shaft, trunk, pipe or channel leading to a ventilator or outlet in the
roof, deck or other part of the building or ship, or to heat the air in or passing
through the ventilator, inlet or outlet, itself by means of an electrically heated
coil, disc, or radiator. The electric current is so arranged that it can be controlled
by a switch cutting off the current as may be required for the increase of the
extracting power and the increase in temperature of the air entering, and the
better ventilation of the building or ship. The air entering is heated as required
by being passed over an electric coil, disc or radiator placed in the inlet panel,
bracket, brick or aperture through the wall, a switch being provided for regulat-
ing or cutting off the current. The invention can be applied for the extraction
of the vitiated air or steam or smoke from any description of building, work,
or place where manufacturing is carried on. It is also applied to heat the air
brought into the building or ship to replace the vitiated air extracted.

I, ROBERT MACKAY, Junior, of 150, Hope Street, Glasgow, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to house and ship ventilators, both for the outlet of the
vitiated air and the inlet of fresh air, and it has for its object to increase the
temperature, as may be required of the air entering or leaving the building
or ship.
In order that my invention may be properly understood and readily carried
into effect, I have appended one sheet of drawings of which,
Figures 1 and 2 are views of different forms of ventilating shafts.

page_text: Figures 3 and 4 are respectively front view and section shewing my improve-
ments as applied for heating buildings.
Figure 5 shews a means of heating the different flats of a building.
Figure 6 illustrates the method of ventilating a room or other compartment
at or near the ceiling by placing a radiator upon a flue formed in the partition
or external wall.
Figure 7 is a view of one form of the radiator.
In carrying out my invention I make use of an electric current to heat the air
in the shaft, trunk, pipe flue, or channel A leading up to a ventilator or outlet
in the roof, deck or other part of the building or ship. Or to heat the air in or
passing through the ventilator,-inlet or outlet,-itself by means of an electrically
heated coil, disc, or radiator.
The electric current is so arranged that it can be controlled by a switch, not
shown, cutting off or regulating the current as may be required for the increase
of the extracting power, and the increase in temperature of the air entering, and
the better ventilation of the building or ship. The air entering the building or
ship is heated as required by being passed over an electric coil, disc, or radiator B,
of any suitable construction placed in the inlet panel, bracket, brick, flue, or
aperture through the wall. A switch is provided for the regulation of the
current.
Referring to Figure 5 it will be observed that I employ a screen C, which acts
as a purifier of the air entering the building and I also provide a door D by which
the admission of the cold air can be completely cut off. I also provide a series
of radiators B and air propeller.
My improvements can be applied for the extraction of the vitiated air or steam
or smoke from any description of building, work, or place where manufacturing
is being carried on. It is also applicable for the heating of the air brought into
the building or ship to take the place of the air extracted.
Of course it is to be understood that although I have shewn one or two forms
in which my improvements might be applied, there may be many other ways
without deviating from the principle of my invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
:-
In the ventilation and heating of buildings, ships, and such like, the application
of an electric current, substantially as herein before described and illustrated on
the accompanying sheet of drawings.
