IMPROVEMENTS IN MEANS FOR THE VENTILATION OF RAILWAY OR OTHER CARRIAGES
Year: 1885

page_text: I ROBERT BOYLE of the firm of Robert Boyle and Son of Holborn Viaduct and
of Glasgow in the County of Lanark North Britain Ventilating and Sanitary
Engineers do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN MEANS FOR THE VENTILATION OF RAILWAY OR OTHER CARRIAGES" to be as
follows:-
My Invention has for its object to effect the ventilation of railway and other
carriages. According to my Invention, I arrange preferably beneath the carriage
a tube or flue or tubes or flues provided with a ventilator preferably of the kind
known as an air pump ventilator and from the said tube or flue or tubes or flues
pipes rise into each carriage preferably through the floor beneath the seats.
Through these passages when the carriage travels air is drawn from the carriage
fresh air being supplied through ventilators or springs preferably at top leading
into perforated tubes extending across the carriage at the upper part near the roof
at the side opposite to that at which the. air is drawn from the carriage. A main
outlet tube or flue or tubes or'flues for the air drawn from the several compartments
of the carriage may be common to all the compartments the pipes form each com-
partment opening into the said tube or flue or tubes or flues. The air may be
withdrawn from and admitted to the carriage at other parts than those named for
example. The fresh air supply may be drawn through a ventilator communicating
with a pipe rising or descending to any convenient position in the carriage and
terminating in an extended and perforated outlet for the proper diffusion of the
air to prevent injurious draughts. Or the air may be exhausted through a
ventilator (preferably of the air pump form) above the lamp and fitted in the
same casing with the lamp and be extracted through perforations or openings
around the lamp so that the same opening answers for the outlet of air and for the
lamp. The air inlet may be through tubes at the sides of the carriage terminating
above the heads of the passengers.

I ROBERT BOYLE of the firm of Robert Boyle and Son of No 64 Holborn
Viaduct and of Glasgow in the County of Lanark, North Britain, Ventilating and
Sanitary Engineers 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 :-
My Invention has for its object to effect the ventilation of railway and other.
carriages I will describe my Invention with reference to the accompanying
drawings Figure 1 of which is a longitudinal section and Figure 2 a transverse
section of a railway carriage provided with means according to my Invention and
figure 3 is a transverse section of a modification hereinafter described. According
to my Invention I arrange preferably beneath the carriage a tube or flue or tubes
or flues as at a provided with a ventilator b preferably of the kind known as an
air pump ventilator and from the said tube or flue or tubes or flues (a) pipes c rise
into each compartment of the carriage preferably through the floor beneath the
seats. Through these passages when the carriage travels air is drawn from the
carriage, fresh air being supplied through ventilators or openings d preferably at
top leading into perforated tubes e extending across the carriage at the upper part
near the roof at the side opposite to that at which the air is drawn from the
carriage The said pipes e are preferably provided with pipes e opening outside
the carriage for draining off any water which may collect therein These pipes e
may if desired be at a little distance above the bottom of the pipes e so as to
retain enough water therein to act as a cooling and purifying medium for the
incoming air-There may be a tube or flue a for each compartment, or a main
outlet tube or flue or tubes or flues for the air drawn from the several compartments
of the carriage may be common to all the compartments as shewn in figure 1 the
pipes from each compartment opening into the said tube or flue or tubes or
lues (a) Although generally I prefer the arrangement described and illustrated yet
the air may be withdrawn from and admitted to the carriage at other parts than
those named for example the fresh air supply may be drawn through a ventilator
as at f Figure 3 communicating with a pipe g rising (or descending in connection
with a ventilator above as at f' and g³ and f³ and g³) to any convenient position
in the carriage and terminating in an extended and perforated outlet for the proper.
diffusion of the air to prevent injurious draughts such for example as the perforated
pipe at h in figure 3 and e in Figure 1 and further the air may be exhausted
through a ventilator (preferably of the air pump form) above the lamp jand
fitted in the same casing with the lamp the air being extracted through perforations
or openings around the lamp so that the same opening answers for the outlet of
air and for the lamp The air inlet when this arrangement is used may with
advantage be at the sides of the carriage as at f in Figure 3 the inlet tubes
terminating preferably above the heads of the passengers.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First. The combination with railway or other carriages of means for admitting
air to the said carriages and withdrawing it therefrom substantially as herein before
described under several modifications and as illustrated by the accompanying
drawings.
Second. In railway carriages or the like the combination with the lamp and
lamp opening of means for effecting the ventilation of the carriages substantially
as hereinbefore described with reference to Figure 3 of the accompanying
drawings.
