to be as follows:―
This Invention consists of an apparatus to deaden the noise of exhaust
steam in the exit pipes of locomotive, steamboat, stationary, and other
engines. I effect this purpose by attaching a pipe of proper area closed
at the end to the exhaust steam pipe, which pipe is perforated with
small holes into which are inserted short bent tubes by which the steam
escapes, thus breaking the waves of sound, when the exhaust pipe is
carried into the smoke stack and rendering the passage of the steam
almost noiseless without interfering with its draft and effecting a con-
siderable saving in the light particles of coal which are consumed instead
of being blown off as usual by the exhaust steam.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Philip Syng Justice in the Great Seal Patent
Office on the 18th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIP
SYNG JUSTICE, of 27, Southampton Buildings, Chancery Lane, London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Eighteenth day of May, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Philip Syng Justice, Her
special licence that I, the said Philip Syng Justice, my executors,
administrators, and assigns, or such others as I, the said Philip Syng
Justice, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 "AN APPARATUS TO DEADEN THE NOISE OF EXHAUST STEAM IN THE
EXIT PIPES OF LOCOMOTIVE, STEAMboat, Stationary, AND OTHER ENGINES, AND TO
ARREST THE SPARKS AND CINDERS THEREFROM," a communication to me from
abroad by Thomas Shaw, of Philadelphia, in the United States of North

page_text: America, upon the condition (amongst others) that I, the said Philip
Syng Justice, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Philip Syng Justice, do hereby
declare the nature of the said 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 of a noise absorber and exhaust nozzle consists of an
apparatus to deaden the noise of exhaust steam in the exit pipes of
locomotive, steam, stationary, and other engines.. I effect this purpose
by attaching a pipe of proper area closed at the end to the exhaust
steam pipe, which pipe is perforated with small holes into which are
inserted short bent tubes by which the steam escapes, thus breaking the
waves of sound, when the exhaust pipe is carried into the smoke stack
and rendering the passage of the steam almost noiseless without inter-
fering with its draft.
The sparks and cinders arising from the smoke box are arrested and
distributed by the said small bent tubes, which effects a considerable
saving in the light particles of coal which are consumed instead of
being blown off as usual by the exhaust steam.
And in order that the said Invention may be properly understood I
will now proceed to describe the same, having reference to the annexed

page_text: Having thus described the nature and object of the said Invention,
I declare that what I claim and desire to be secured to me by the herein-
before in part recited Letters Patent is, the apparatus to deaden the
noise of exhaust steam in the exit pipes of locomotive, steamboat,
stationary, and other engines, and also to arrest the sparks and cinders
therefrom, substantially as herein-before described and shewn on Drawing
or any mere modification thereof.
Having thus described the nature and object of the said Invention,

noise of exhaust steam in the exit pipes of locomotive, steamboat,
stationary, and other engines, and also to arrest the sparks and cinders
therefrom, substantially as herein-before described and shewn on Drawing
or any mere modification thereof.
In witness whereof, I, the said Philip Syng Justice, have hereunto
set my hand and seal, this Eighteenth day of November, One
thousand eight hundred and seventy-five.
