Improved Means for Ventilating Railway Carriages and other
Vehicles.
I ARTHUR BRANSTON CONSTANTINE, of Bollings Mill, Bradshaw Gate, Bolton,
Lancashire, Cotton Waste Dealer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to he particularly described and
ascertained in and by the following statement :-
This invention relates to improved means for ventilating railway carriages and
other carriages, by a continuous current of fresh air caused to enter same by the
velocity with which they are travelling.
And in order that my invention may be more readily understood, I have shewn
same upon the accompanying sheet of drawings, in which:
Fig. 1 is a front view of the apparatus,
Fig. 2 being a side view of same applied to a railway carriage.
The invention consists in a tube or pipe A, provided at its lower extremity with
a curved part terminating in a funnel or bell-mouthed aperture B.
Where the invention is to be applied to railway vehicles, the said tube or pipe
will be supplied with two apertures B. B' as shewn in Fig. 2, so that whichever
way the vehicle is travelling, one of these apertures will face the front or travelling
direction of the train, and so receive the rush of air.
The tube or pipe A which forms an air-passage, is fixed into the vehicle in a
vertical position, in any convenient part of same, the upper extremity or outlet C
of the said air-passage being curved as shewn and provided with a suitable
regulator D for the purpose of checking or increasing, as desirable, the current of
air that is allowed to pass through the said out-let C. As will be readily seen,
from the position of the inlets B. B', the current of air caused to enter the vehicle,
will always be comparatively pure and cool, even when the vehicle is passing
through a tunnel, as the inlets being on a low level, escape all the smoke and foul
gases and air which rise to the top of the tunnel.
For use with broughams and other like road vehicles, the air-passage A is only
provided with one inlet instead of two.
The said air-passage can be fixed into any part of the vehicle which is convenient.
In the case of railway carriages, 1 preferably fix the air-passage in the partitions
which divide the carriages into compartments, and also the said air-passage can be
provided with two outlets instead of one, for the purpose of making one air-
passage ventilate two or more compartments.
The said air-passage A may be inade in the form of a circular tube, or it may be
made flat or square whichever is desirable or convenient.
Having now particularly described and 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 :-
An air-passage A provided with inlets B, and outlets C and regulators D,
by means of which a current of pure air is conveyed to the interior of a vehicle,
substantially as in manner described and shewn and for the purpose set forth.
