Improvements in Ventilators for Ventilating Carriages, Ships'
Cabins, Railway Vehicles, and Spaces or Apartments generally
in Travelling Vehicles or Vessels.
I, FREDERICK SHANKS of the Firm of Frederick & Robert Shanks of 70
and 71 Great Queen Street, and 30 New Bond Street in the County of London,
Carriage Builders do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide simple and efficient means for
ventilating carriages, ships' cabins, railway vehicles, and spaces or apartments,
generally, in travelling vehicles or vessels. A ventilator according to my invention
consists of a passage or tube extending at each end into the open air and having in
it openings communicating with the space or apartment to be ventilated, the
arrangement, and construction being such that as the vehicle, or vessel, travels
along air currents pass through the said passage or tube and these air currents draw
vitiated air from the space or apartment through the said openings and carry. it
away through the outlet. As applied to an ordinary brougham, for example, the
passage or tube may be extended along the roof of the carriage and open to the
outer air through both the front and back of the carriage. The said passage or
tube may be made in copper, tin-plate, or any other suitable metal, or other
material, and may be formed in one length, or in two, or more lengths, say in several
lengths, one of which is inserted through an opening in the front of the carriage
and another through an opening in the back of the carriage, the remaining length
or lengths, being fitted on, or secured to, the others, so as to make a continuous
passage from front to back of the carriage. Openings are made in the said passage
or tube, which openings are in communication with the inside of the carriage, and
are preferably provided with deflecting pieces which will prevent the currents of
air, when the carriage is in motion, from passing into the carriage and will
properly direct the air currents through the passage, or tube, and from the carriage.
Any suitable openings may be provided at any suitable part or parts of the
carriage, if necessary, to admit fresh air to replace that withdrawn. I prefer to
make the passage, or tube, of a flattened form and to make the openings thereinto
for vitiated air in the sides thereof, but the said passage may be of any other
suitable shape, and the openings may be in any other desired position.
The invention may be similarly applied to ships cabins, railway carriages, or the
like, the passage or tube, being led from any suitable air inlet and terminating at
any suitable place of discharge.

Improvements in Ventilators for Ventilating Carriages, Ships'
Cabins, Railway Vehicles, and Spaces or Apartments generally
in Travelling Vehicles or Vessels.
I FREDERICK SHANKS of the Firm of Frederick and Robert. Shanks of 70
and 71 Great Queen Street, and 30 New Bond Street in the County of London,
Carringe Builders, do hereby declare the nature of my 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 provide simple and efficient means for
ventilating carriages, ships' cabins, railway vehicles, and spaces or apartments,
generally, in travelling vehicles or vessels. A ventilator according to my invention
consists of a passage or tube extending at each end into the open air and having in
it openings communicating with the space or apartment to be ventilated the
arrangement, and construction being such that as the vehicle or vessel, travels
along air currents pass through the said passage or tube and these air currents
draw vitiated air from the space or apartment through the said openings and carry
it away through the outlet. I will describe my invention more fully with reference
to the acccompanying drawing which represents it applied to an ordinary
brougham from which its application to other vehicles and places will be readily
understood,
Figure 1 of the drawing represents in longitudinal section the upper part and
roof of the carriage and
Figure 2 an underside view of the ventilating device.
C
A is a passage or tube extending along the underside of the roof B of the
carringe and open at its opposite ends a and b to the outer air through both the
front and back of the carriage the end a for the entrance of the air to the tube or
passage being preferably made trumpet shaped or widened as shown. The said
passage or tube A may be made in copper, tin-plate or any other suitable metal, or
other material, and may be formed in one length, as shewn, or in two, or more
lengths, say in several lengths, one of which may be inserted through an opening
in the front of the carriage and another through an opening in the back of the
carriage, the remaining length or lengths, being fitted on, or secured to, the others
so as to make a continuous passage from front to back of the carriage. Openings
are made in the said passage or tube, which openings are in communication with
the inside of the carriage, and are preferably provided with deflecting pieces d
which will prevent the currents of air entering the passage at a when the carriage
is in motion from passing into the carriage, and will properly direct the air currents
through the passage or tube, and from the carriage and out through the end b.
Any suitable openings may be provided at any suitable part or parts of the
carriage, if necessary, to admit fresh air to replace that withdrawn. I prefer to
make the passage, or tube, of a flattened form as shewn and to make the openings
thereinto for vitiated air in the under side thereof, but the said passage may be
of any other suitable shape, and the openings e may be in any other desired
position.
The invention may be similarly applied to ship's cabins, railway carriages or the
like, the passage or tube, being led from any suitable air inlet and terminating at
any suitable place of discharge.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that what
I claim is
1. A ventilator for carriages, ships' cabine, railway vehicles and spaces or
apartments generally in travelling vehicles or vessels, the said ventilator consisting

page_text: of a passage or tube communicating at each end with the open air and having
openings therein communicating with the space or apartment to be ventilated and
provided or not with deflecting pieces substantially as hereinbefore described.
2. The combination and arrangement of parts constituting means for ventilating
carriages, ships' cabins, railway vehicles and spaces or apartments generally in
travelling vehicles or vessels, substantially as herein before described and illustrated
by the accompanying drawing.
