I CHARLES SHENTON DU SAUTOY of Linden, Denzil Avenue Southampton Supt
Engineer Union Steam Ship Company Limited do hereby declare the nature of my
said invention to be as follows
-
When steam is allowed to stand in pipes from which the heat of the steam becomes
dissipated by condensation and radiation, such pipes will become more or less filled
with water formed by the condensation of the steam Then if the contents of the
pipe water, or water and steam-be allowed to pass to any instrument, apparatus,
engine, or appliance, depending for its effective operation upon dry steam, some con-
siderable time must elapse under the present ordinary conditions of working before
the machine, or other thing will be provided with dry steam and will work properly
and efficiently
As the presence of water in the working fluid is the cause of
inefficient working, then until it is got rid of, the appliance, or other thing cannot
work properly Now the object of my invention is to prevent the water condensed as
described, entering the working parts of appliances, instruments engines and machines
and to provide means to drain off the water To this end I provide in conjunction
with the steam supply pipe of any appliance, machine, engine or other thing a second
"turned on the
pipe which is so combined with the supply pipe that when steam is
water existing in such supply pipe falls down such second pipe, instead of being forced
by the steam into the machine or appliance or other thing as under the present
ordinary manner of supplying steam would be done, thus by my invention the water
is intercepted and drawn off and dry steam supplied directly steam is "turned on
My invention can be applied with great advantage to steam whistles as in most
cases the steam in the pipe leading from the source of supply to the whistle remains in
t turned
such pipe and gradually condenses Then as a consequence when steam is
on" to the whistle instead of steam issuing through the exit orifice water is for some
ame blown out and accordingly as more or less water exists in the pipe, the whistle

In applying my invention to a steam whistle the supply pipe is provided with a

connected to the supply pipe and it is so arranged that when steam is "turned on" to
the whistle the water in the supply pipe is forced up and falls automatically down the
second draw off pipe At the point at which the water is intercepted or drawn off
the pipes may be bifurcated or connected forming a water separating or intercepting
portion or chamber
This invention in whole or in part may be applied to steam engines, steam heating
apparatus and other apparatus appliance or instruments requiring dry steam

1 CHARLES SHENTON DU SAUTOY, of Linden, Denzil Avenue, Southampton, Supt
Engineer, Union Steam Ship Company Limited, do hereby declare the nature of my
sud invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement
-
When steam is allowed to stand in pipes from which the heat of the steam becomes
dissipated by condensation and radiation, such pipes will become more or less filled
with witer formed by the condensation of the steam Then, if the contents of the
pipe-water, or water ind steam-be allowed to pass to any instrument, appírītus,
engine, or appliance depen ling for its effective operation upon dry steam, some
consider time must elipse under the present ordinary conditions of working before
the machine or other thing will be provided with dry steam and will work properly
and efficiently As the presence of water in the working fluid is the cause of
inefficient working, then until it is got rid of, the appliance, or other thing innot
work properly Now the object of my invention is to prevent the water condensed as
described, entering the working parts of appliances, instruments, engines and
machines, and to provide means to drun off the water To this end I provide in con-
junction with the steam supply pipe of any appliance, machine, engine, or other thing,
" turned
second pipe which is so combined with the supply pipe, that when stem is
on, the water existing in such supply pipe falls down such second pipe, instead of
being forced by the steam into the machine, or appliance, or other thing, as under the
present ordinary manner of supplying sto im would be done, thus by my Invention
the water is intercepted and drawn off, and dry steam supplied, directly stcun is
' turned on
My invention can be applied with great advantage to steam whistles is
in most cases the steam in the pipe leading from the source of supply to the whistle
remains in such pipe and gradually condenses Then, as a consequence, when steam
19 turned on
to the whistle, instead of steam issuing through the exit orifice, water
18 for some time blown out, and accordingly as more or less water exists in the pipe,
On board
the whistle for a longer or shorter period will not commence to sound
onditions,
navigable vessels this delay of operation of the whistle may, under some
occasion series danger of collision the spraying too of water is a source of incon-
venience and annoyance to passengers and bystanders

In applying my invention to a steam whistle, the supply pipe is provided with a
cock or valve, as is also the water return pipe, which may be in couimunication with

the boiler Near to the whistle the second or water draw off or return pipe is con-
necte to the supply pipe, and it is so arranged that when steam is
" turned on to
the whistle the water in the supply pipe is forced up and falls automatically down the
second or draw off pipe The point at which the water is intercepted or drawn off, the
pipes may be bifurcated or connected, forming a water separating or intercepting
portion or chamber
This invention in whole or in part may be applied to steam engines, steam heating
apparatus, and other apparatus, appliances, or instruments, requiring dry steam
The drawing hereunto annexed and forming a part of this Specification serves to
illustrate the Invention as above described applied to the steam supply pipe of a steam
whistle For convenience of space the drawing is shown in two parts
With reference to the drawing A designates a steam whistle, B is the usual coch
or valve of the whistle, C is the steam supply pipe from the boiler, D is a valve on
the steam supply pipe C, worked by the screwed spindle e and wheel ei, E is the water
intercepting pipe provided with valve F worked by the screwed spindle fund
wheel, and communicating with the supply pipe (through the bifurcated branch C"
In action when the valve D is opened and steam is " turned on to the whistle A, iny
water which may be condensed in the supply pipe C will be forced up it, and, at the
point of bifurcation of the branch of the pipes C and E, will fill automatically
down the passage leading to the return pipe E and by opening the valve F this
water (condensed steam) can be blown away through a waste pipe, or returned to the
boiler
By this arrangement when the cock or valve B of the whistle A is opened, only
dry steam will be supplied to the whistle, that is, practically no water will be carried
into the whistle with the steam, and the action of the whistle will consequently take
place instantly its steam valve is operated, and the sound will at once be cle ir, and
besides this water is not blown through the whistle to the discomfort and annoyance
to bystanders
In the application of my Invention to other purposes than that above described in
reference to the drawings, such as to steam engines, heating apparatus, or other
apparatus in which dry steam is required, the vertical supply pipe bifurcited
branch C (or equivalent connection), and the water intercepting and carrying off
pipe E would be used, the supply of dry steam to the machine or appliance being
taken away from the top of the branch " above the point of junction of the two
bifurcated passages, just in the same way as it is led therefrom to the whistle described
with reference to the Drawings
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I
clum 15-
1 The means substantially herein described for intercepting and drawing off water
(condensed steam) from the steam supply pipes of steam whistles, steam engines,
steam heating apparatus ind other appliances, which means consist in providing on d
steam supply pipe, a device having two pipes vertically arranged, one of which serves
as a continuation of the steam pipe, and the other serves to carry off the water, said
pipes communicating by a branch, at which point the water is intercepted, so that
when steam is turned on, the water existing in such supply pipe is caused to fall down
such second pipe and is led away
2 In means for intercepting or drawing off water (condensed steam) from the
steam supply pipe of appliances, instruments, or machines, in which dry steam 18
required, the combination of a vertical portion of the steam supply pipe, a second pipe
in communication with the said supply pipe, and a valve for removing the water
(condensed steam) from the supply pipe, as set forth
