A NEW MODE OF VENTILATING CLOSE CARRIAGES
Year: 1821

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FREDERICK ARCHBOLD, of Serjeant's Inn, Fleet Street, in the City of London,
Esquire, send greeting.
WHEREAS His present Majesty King George the Fourth, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the First day of November last, for Himself, His heirs and successors,
did give and grant unto me, the said John Frederick Archbold, His special
licence, full power, sole privilege and authority, that I, the said John Frederick
Archbold, my executors, administrators, and assigns, and every of them, by
myself and themselves, or by my and their deputy and deputies, servants or
agents, or such others as I, the said John Frederick Archbold; my executors,
administrators, or assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term of years therein
unexpired, should and lawfully might make, use, and exercise, within England;
Wales, and the Town of Harwich-upon-Tweed, my Invention of. "A NEW
MODE OF VENTILATING CLOSE CARRIAGES;" in which said Letters Patent there
is contained a proviso obliging me, the said John Frederick Archbold, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is

page_text: to be performed, and to cause the same to be enrolled in His Majesty's High
Court of Chancery within two calendar months next and immediately after
the date of the said recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Frederick Archbold, do hereby describe and ascertain the nature of my
said Invention, and in what manner the same is to be performed, by the
following description thereof; that is to say:-
In the first place, the air already in the carriage is abstracted by means of
pipes or tubes passing from the inside of the carriage through the side or front
thereof into the lamps, by which means, when the lamps are lighted, and the
air thus therein rarified, the air from the inside of the carriage will pass out
through the said pipes or tubes into the lamps, and thence through the
apertures in the upper parts of the said lamps. Or, instead of having the
lamps on the outside, a lamp or lamps may be placed in the inside of the
carriage, such lamp having an aperture or opening at the bottom or side
thereof, with an open tube passing from the top of the lamp to the outside of
the carriage. Secondly, the place of the air thus abstracted will be supplied
from the outside of the carriage by means of an open tube or tubes passing
from the outside of the carriage to the inside. This tube or tubes I usually
pass along the inside of the roof of the carriage between the ribs, and
extending to the centre thereof; but they may be introduced at the sides or
such other part of the carriage as may be thought most convenient. The
several pipes or tubes herein mentioned I usually make flat, in order that
they may lie more conveniently under the lining of the carriage; and in the
flat side of each tube, near that end thereof which is inside the carriage, and
next the lining, I insert a ventilator of the usual form. In order that the
passengers may regulate the quantity of air to be admitted or abstracted, holes
are cut in those parts of the lining of the carriage where the ventilators come,
for the purpose of allowing the ventilators to appear above the lining, the
lining still concealing the other parts of the tubes. These pipes or tubes,
however, instead of being made flat, may be round or square, and may be
finished with ventilators or not, and passed either under or over the lining, as
may be deemed most convenient or desirable.
In witness whereof, I have hereunto set my hand and seal, the Thirty-
first day of December, in the year of our Lord One thousand eight
hundred and twenty-one.
JOHN FRED*, ARCHBOLD. (L.S.)
