Apparatus for Ventilating Carriages.
We, WILLIAM SHERMAN, of No. 19 Great Coram Street, Russell Square, in the
County of Middlesex, Builder, and GEORGE CORDWELL of Moorgate Street Chambers,
Moorgate Street, in the City of London, Solicitor, do hereby declare the nature of
this invention to be as follows:-
This invention relates to apparatus for ventilating carriages, so arranged that it
effects a change of air to an extent that can be regulated at will, without exposing the
occupants to unpleasant draughts, and that the parts which are seen within the carriage
are not unsightly in appearance.
For this purpose, we fix under the front part of the carriage body a mouthpiece
directed forwards from which a tube leads up the middle of the front within the
carriage to a tube which extends each way along the angle which the ceiling makes
with the front, this tube being bent if required to suit the curve of the front, and being
perforated with numerous small holes near its upper side.
Just below these holes a lip inclining upwards stands out from the tube so as to
direct the jets of air from the perforations upwards towards the ceiling.
At a convenient height we provide in the upright tube a cock or valve by which to
regulate the quantity of air that is caused by the advance of the carriage to ascend
the tube from the mouth piece.
In some cases, instead of a single central upright tube we employ two, one at each
side of the front communicating with the perforated tube and provided with regulating
cocks or valves. At the back of the carriage near the ceiling we provide several tubes
communicating with the outside for the escape of the vitiated air, and, in order to
prevent unpleasant indraughts by these tubes in case of wind blowing against the
back of the carriage, we provide each of the tubes with a deflector which directs
such air as may blow in upwards or sideways without descending on the heads of the
persons occupying the back seat.

We, WILLIAM SHERMAN of No. 19 Great Coram Street Russell Square in the County
of Middlesex, Builder, and GEORGE CORDWELL of Moorgate Street Chambers Moorgate
Street in the City of London, Solicitor, 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 apparatus for ventilating carriages, so arranged that it effects
a change of air to an extent that can be regulated at will, without exposing the
occupants to unpleasant draughts, and that the parts seen within the carriage are not
unsightly in appearance. For this purpose we adopt arrangements such as are shewn
by the accompanying drawings, applied to a brougham or like carriage.
Fig. 1 is a vertical section through the body of the carriage, Fig. 2 is a view of the
front as seen from the interior.
Under the front part of the carriage body we fix a mouthpiece A directed forwards.
From this mouthpiece two tubes B lead up the front angles of the carriage to a
cross tube which may be, like C close up to the ceiling, or, like D, it may cross just
under the front windows. In some cases, instead of carrying two tubes B upwards,
we carry up a single central tube, as indicated by the dotted lines E, communicating
with the cross tube C or D. The cross tube C or D is perforated with a number of
small holes, in front of which is fixed a bent plate F to act as a deflector, directing
upwards and diffusing the air that issues from the perforations. In a convenient part
of each of the tubes B or E is fitted a throttle valve G by which the area of passage
through the tube can be regulated at will. Through the back of the carriage near the
ceiling we provide several tubes H closed at their inner ends but open at their outer
ends to the atmosphere and also having openings I within the carriage on their upper
sides. As the carriage moves onwards, air entering the mouth piece A ascends the
tubes B or the single tube E to the cross tubes (or D and issues into the carriage in
a diffused manner. Also air, more or less fouled, passes from the upper part of the
carriage out through the pipes H. Should there be wind blowing in through the
pipes H, the currents are directed upwards by the openings I so that they do not annoy
the
passengers.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
Apparatus for ventilating carriages constructed and arranged substantially as herein
described and illustrated.
