Year: 1867

page_text: LETTERS PATENT to William Gaudly Creamer, of Woburn Place, Russell
Square, in the County of Middlesex, Engineer, for the Invention of
"IMPROVED AUTOMATIC APPARATUS FOR THE VENTILATION OF RAILWAY
CARRIAGES, OMNIBUSES, AND OTHER VEHICLES, AND THE CABINS OF STEAM-
BOATS."
Sealed the 17th January 1868, and dated the 20th July 1867.
PROVISIONAL SPECIFICATION left by the said William Gaudly Creamer
at the Office of the Commissioners of Patents, with his Petition, on the
20th July 1867.
I, WILLIAM GAUDLY CREAMER, of Woburn Place, Russell Square, in the
County of Middlesex, Engineer, do hereby declare the nature of the said
Invention for "IMPROVED AUTOMATIC APPARATUS FOR THE VENTILATION OF RAIL
WAY CARRIAGES, OMNIBUSES, AND OTHER VEHICLES, AND THE CABINS OF STEAM-
BOATS," to be as follows:-
This Invention consists in the construction and arrangement of certain
apparatus which acts automatically, and is applicable for the ventilation of
railway carriages, omnibuses, and other vehicles, and also of the cabins of
steamboats.
Openings of any desired dimensions are made in the sides and near the
ceiling or roof of the carriage, vehicle, or cabin to be ventilated, and in each
of these openings is placed a vertical wicket, such wicket being supported on

page_text: pivots, so that it can move backwards or forwards. The outer end of the
wicket projects a short distance from the outer side of the carriage, vehicle,
or cabin, and stands at an angle therewith of about forty-five degrees. When
the train, vehicle, or steamboat is in motion the counter current of air at the
side thereof impinges against the wickets, thus causing a strong and constant
exhausting current from the inside of the carriage, vehicle, or cabin outwards.
When the direction of transit of the train, vehicle, or steamboat is changed
the wickets shift by reason of the counter current which comes into operation,
and are reversed in position, a similar process of ventilation being thus effected.
A door is provided opposite each of the apertures, by which they can be
entirely closed when desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Gaudly Creamer in the Great Seal Patent Office
on the 20th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GAUDLY CREAMER, of Woburn Place, Russell Square, in the County of
Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Gaudly Creamer, Her special licence that I, the said William
Gaudly Creamer, my executors, administrators, and assigns, or such others
as I, the said William Gaudly Creamer, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVED AUTOMATIC APPARATUS FOR THE VENTILATION OF RAILWAY
CARRIAGES, OMNIBUSES, AND OTHER VEHICLES, AND THE CABINS OF STEAM BOATS,"
upon the condition (amongst others) that I, the said William Gaudly
Creamer, my executors or adminstrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal

page_text: Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Gaudly Creamer, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying Drawings,
and the figures and letters marked thereon, that is to say :-
My said Invention consists in the construction and arrangement of certain
apparatus which acts automatically, and is applicable for the ventilation of
railway carriages, omnibuses, and other vehicles, and also of the cabins of
steamboats.
Openings of any desired dimensions are made in the sides and near the
ceiling or roof of the carriage, vehicle, or cabin to be ventilated, and in each
of these openings is placed a vertical wicket, such wicket being supported on
pivots, so that it can move both backwards and forwards. The outer end of
the wicket projects a short distance from the outer side of the carriage, vehicle,
or cabin, and stands at an angle therewith of about forty-five degrees. When
the train, vehicle, or steamboat is in motion the counter current of air at the
sides thereof impinges against the wickets, thus causing a strong and constant
exhausting current from the inside of the carriage, vehicle, or cabin outwards.
When the direction of transit of the train, vehicle, or steamboat is changed
the wickets shift by reason of the counter current of air which comes into
operation and are reversed in position, a similar process of ventilation being
thus effected. A door is provided opposite to each of the apertures, by which
they can when desired be entirely closed.
My said Invention will be more clearly understood by reference to the
accompanying Drawings.
Figure 1 is a longitudinal section of the side of a carriage, which is
indicated by the letters A, B. The opening is shewn at C, D, E being the
vertical wicket which works on the pivot G and projects outwards about three
inches from the side of the carriage.
Figure 2 shews the external appearance of the ventilator, the same letters
of reference being used as in Figure 1.
Having thus declared and ascertained the nature of my said Invention, and
the manner in which it is to be performed, I would observe in conclusion that
what I consider novel and original and therefore claim as constituting the
Invention secured to me by the said herein-before in part recited Letters
Patent is, the construction and arrangement of automatic ventilating apparatus

page_text: as and for the purposes substantially herein-before set forth and described, or
any mere modifications thereof.
In witness whereof, I, the said William Gaudly Creamer, have hereunto
set my hand seal, this Twentieth day of January, in the year of our
Lord One thousand eight hundred and sixty-eight.
W. G. CREAMER. (L.S.)
