WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Mason Cook, Her special licence that I, the said John
Mason Cook, my executors, administrators, and assigns, or such others as
I, the said John Mason Cook, 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 Invention
for "IMPROVEMENTS IN RAILWAY CARRIAGES AND ALL OTHER SPRINGED VEHICLES,"
upon the condition (amongst others) that I, the said John Mason Cook,
my executors or administrators, 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 Patent.
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said John Mason Cook, 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 thereof, reference being had to the Drawing hereunto annexed,
that is to say:-
The objects of my Invention are to prevent noise and to diminish the
oscillation of railway carriages and other springed vehicles, and the Invention
consists in the introduction of vulcanized india-rubber or any other substance
which will act as a non-conductor of sound between the wheels or springs and
the body of the vehicle.
The accompanying Drawing illustrates one method of carrying my Invention
into effect as applied to a railway carriage.
A is the floor, and B the frame of the carriage, between which I place a
layer of vulcanized india-rubber, vulcanite,. or any other substance which will
act as a non-conductor of sound, of, say, about of an inch in thickness, and
the full width of the framework of the carriage; D is a brace or strap con-
necting the springs, between which brace or strap and the frame of the
carriage I place a layer of the sound-deadening material of, say, about 1 inch
in thickness, and sufficiently wide to prevent the iron and wood coming in
contact; E, E, are the axle guards, between which and the frame of the

page_text: carriage I insert a layer of the before mentioned material, say, about
an inch
in thickness, and about 1 inch wider and deeper than the axle guards; these
layers are let into the frame of the carriage behind the axle guards. In the
construction of springed vehicles of every description I apply the before-
mentioned materials to all parts connecting the springs, axles, and wheels, to
the body of the vehicle. I bore the holes in the sound-deadening material
rather smaller in diameter than the screws or pins such holes are intended to
receive in order that they may fit tightly; and I place a washer of the aforesaid
material between the heads of the screws or pins and the parts with which
they usually come in contact, and likewise between the nuts and the iron or
wood, as the case may be.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, constructing
railway carriages and other springed vehicles with vulcanized india-rubber, or
any other substance which will act as a non-conductor of sound, between the
wheels or springs and the body of the vehicle, substantially as herein-before
described and illustrated in the accompanying Drawing.
In witness whereof, I, the said John Mason Cook, have hereunto set my
hand and seal, this Seventeenth day of March, One thousand eight
hundred and sixty-four.
