at the Office of the Commissioners of Patents, with his Petition, on
the 21st September 1859.
I, WLLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "AN IMPROVED MODE OF AND APPARATUS FOR CONDENSING
THE WASTE STEAM OF MARINE ENGINES," to be as follows:-
This Invention of an improved mode of and apparatus for condensing the
waste steam of marine engines, relates to a novel mode of effecting the con-
densation of the waste steam that is usually allowed to blow off through the
waste pipe near the funnel of steam vessels. In blowing off steam in the
ordinary manner through this pipe a considerable noise is made by the rush of
the steam, and one of the objects of the present Invention is to prevent.
this noise.
In carrying out the Invention, it is proposed to conduct the waste steam

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of September, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Newton, Her special license that I, the said
William Edward Newton, my executors, administrators, and assigns, or such
others as I, the said William Edward Newton, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "AN IMPROVED MODE OF AND APPARATUS FOR CONDENSING THE
WASTE STEAM OF MARINE ENGINES," being a communication from abroad by
Messrs. Mazeline and Co., of Paris, in the Empire of France, upon the con-
dition (amongst others) that I, the said William Edward Newton, by an
instrument in writing under my hand and seal, 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,

page_text: NOW KNOW YE, that I, the said William Edward Newton, 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, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention of an improved mode of and apparatus for condensing the
waste steam of marine engines, relates to a novel mode of effecting the con-
densation of the waste steam that is usually allowed to blow off through the
waste pipe near the funnel of steam vessels. In blowing off steam in the
ordinary manner through this pipe, a considerable noise is made by the rush
of the steam, and dense white clouds are also formed. The object of the
present Invention is to obviate the necessity of discharging the steam in this
way, and thereby to prevent the noise caused by the rush of steam, and the
appearance of the dense white clouds.
In carrying out the Invention, it is proposed to conduct the waste steam
from the escape valves down a pipe to an injecting apparatus provided with a
conical jet, which forms the exit end of the waste steam pipe. This conical
jet is enclosed within a conical cover placed at the lower end of another pipe,
which communicates by means of a cock with a pipe filled with water, either
from the outside of the vessel, or from a reservoir in the vessel itself, such as
the well where the bilge water collects. Upon the steam being allowed to
rush into the exit pipe and out at its conical end, it will cause a vacuum in the
water pipe, and force the cold water up the latter, and condense the steam as
it issues from the jet. The force of the steam will, nevertheless, be sufficient
to expel the water from the pipe by forcing it upwards and out at the upper
end, either into the boiler, or through the side of the vessel into the sea
without making any noise, and as the water is expelled at the top by the
steam, fresh cold water will rush into the pipe. In this way a current of cold
water will be always ready to condense the steam as it issues from the jet into
the water pipe. As the injecting apparatus communicates by means of
suitable pipes with the bilge water well, the waste steam may be made to
pump water from the ship into the sea.
In the accompanying Drawings I have shewn an arrangement of apparatus
whereby the objects of the present Invention may be effected.
Fig. 1 represents a transverse vertical section of a steam vessel, shewing
the improvements adapted to the boilers; Fig. 2 is a plan view of the
injecting and condensing apparatus, as seen from above; Fig. 3 is a longi-
tudinal elevation of a portion of a boiler provided with the improved apparatus;
Figs. 4, 5, and 6, represent different views of some of the parts of the injecting

page_text: apparatus, shewn in detail. In Figs. 1 and 3, the blue lines indicate the old
arrangement of apparatus, which consisted, as may be seen, in taking the
steam from the valves S and S¹, and conducting it into the vertical tube placed
beside the chimney or funnel, and from which tube it escaped into the air.
By the employment of the improved injecting and condensing apparatus, the
steam which escapes from the valves S and S¹ enters the horizontal part of the
tube T, whereby it is conducted down a vertical pipe to the injecting
apparatus U. This apparatus (the details of which are shewn at Figs. 4, 5,
and 6,) is composed of a conical plug or piece A enclosed within a conical
envelope B, provided with a tubular opening communicating with a two-way
cock C, which establishes a communication by means of the branch pipe D
with the sea water outside the vessel and the injector V, and also through the
pipe E with the bilge water near the keel and with the injector. The
envelope B of the injector is supported by the arms b, which are fixed against
the sides of the vessel, and provided at the outer end with a ring which
surrounds the exit tube T', that is bent at its upper end, so as to pass through
the ship's side and empty itself above the water line of the vessel.
tube T is closed at pleasure by a clack t. The apparatus acts in the following
manner When, from any cause, the steam owing to an increase of pressure
in the boiler escapes by the valves S it is received by the pipe T, which brings
it directly under the conical piece A of the injector. The cock C is then
opened, so that the sea water may penetrate or enter the envelope B, into
which the steam from the valves S immediately enters and draws the water
from the outside, and causes it to rise in the vertical pipe T¹, and escape
without noise in a very regular manner into the water outside the vessel. The
effect will be the same if a communication be opened through the tube E
between the bilge water near the keel and the injector. The suction of the
steam when allowed to pass into the injector causes the bilge water to enter
the conical part of the injector, and rise in the ascending tube T¹. By this
means a continuous suction will be maintained, and made to draw the water
from near the keel, and discharge it without noise by the pipe T¹.
The
Having now described this Invention of an improved mode of and apparatus
for condensing the waste steam of marine engines, as communicated to me by
my foreign correspondent, and explained the manner of carrying the same
into effect, I would remark, that although I have shewn and described a con-
venient form or arrangement of apparatus to be employed for the purpose of
the present Invention, I do not mean or intend to confine myself rigidly
thereto, as it may be doubtless varied in many particulars without departing
from the nature and object of the present Invention; but that which I consider

page_text: to be new, and therefore wish to claim as the Invention secured to me by
Letters Patent as aforesaid, is, the mode herein set forth, together with the
apparatus above described, or any mere modification thereof for condensing the
waste steam of marine engines.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Nineteenth day of March, in the year of
our Lord One thousand eight hundred and sixty.
