Improvements in Arrangements for Separating Liquids from Steam
in Motion, and in Combining such Arrangements with Apparatus
for Feeding Steam Generators with Water.
I ARTHUR SLATER SAVILL of 65 Park View, Queens Park, Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of the said invention, to
be as follows:-
.:
1. My improvements are or may be combined with pipes or passages conveying
steam from a boiler to the cylinder of the engine to dry the steam or keep back
liquids carried along with it when in motion passing from the boiler to the Engine or
may be used for the like purpose where steam is passing through pipes or passages
for other purposes, or for separating liquids in a state of water or grease from steam
exhausted from steam Engines, and consists in the use of one or more thin plates
having numerous perforations or slits against which thin plates the steam infringes
and passes through the holes or slits therein.
On that side of the plates against which the steam strikes, a projecting rim or
margin is formed round each hole or slit so that the liquid moisture, whether water or
grease which comes upon the surface of the plates between the holes or slits can run
down the face of the plates (which are arranged in a vertical position) and is thus not
likely to be carried through the holes or slits by the current of steam passing through
them but will run down the face of the plates to the lower part of the chamber in
which the plates are arranged and may be then drawn off by a "steam trap" or other
suitable arrangement or where applied for preventing liquid from passing with the steam
from the boiler to the Engine, the liquid thus separated is or may be returned to the
boiler.
The plates are arranged when more than one is used so that the holes or slits in
one plate will be opposite the blank places between the holes or slits in the adjoining
plates.
2. In applying my invention where exhaust steam is used for feeding the boiler I
place the separating arrangement in the passage or pipe or in a chamber formed in
the passage or pipe between the exhaust pipe and the Injector and thus only operate
upon such portion of the exhaust steam as is required by the Injector, leaving the
surplus exhaust steam not required to pass away in the ordinary manner.
Dated this Second day of August 1887.

page_text: Improvements in Arrangements for Separating Liquids from Steam
in Motion, and in Combining such Arrangements with Apparatus
for Feeding Steam Generators with Water.
I ARTHUR SLATER SAVILL of 65 Park View, Queens Park, Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
1. My improvements are or may be combined with pipes or passages conveying
steam from a boiler to the cylinder of the Engine or Engines to dry the steam or
keep back liquids carried along with it, when in motion passing from the boiler to
the Engine or Engines or may be used for the like purpose where steam is passing
through pipes or passages for other purposes or for separating liquids in a state of
water or grease from steam exhausted from steam Engines, and consists in the use
of one or more plates (thin by preference) having numerous perforations or slits
against which thin plates the steam impinges and passes through the holes or slits
therein.
On that side of the plates against which the steam strikes a projecting rim or
margin is formed round each hole or slit so that the liquid moisture whether water or
grease which comes upon the surface of the plates between the holes or slits can run
down the face of the plates (which are arranged in a vertical position by preference)
and is thus not likely to be carried through the holes or slits by the current of steam
passing through them but will run down the face of the plates to the lower of
part
66
the chamber, in which the plates are arranged and may be then drawn off by a steam
trap or other suitable arrangement, or where applied for preventing liquid from
passing with the steam from the boiler to the Engine the liquid thus separated is or
may be returned to the boiler.
The plates are arranged when more than one is used so that the holes or slits in one
plate will be opposite the blank places between the holes or slits in the adjoining
plates when the holes or slits in the plates are to be nearly in the same line.
2. In applying my invention where exhaust steam is used for feeding the boiler I
place the separating arrangement in the passage or pipe or in a chamber formed in
the passage or pipe between the exhaust pipe, and the Injector and thus only operate
upon such portion of the exhaust steam as is required by the Injector, leaving the
surplus exhaust steam not required, to pass away in the ordinary manner.
Fig. 1 is a sectional elevation illustrating one modification of my invention.
Fig. 2 is also a sectional elevation illustrating another modification.
Fig. 3 is also a sectional elevation of a modification similar to that shown by fig. 1,
but with a throttle valve combined with the casing.
Fig. 4 is a sectional elevation illustrating my invention combined with an Exhaust
steam or combined Exhaust steam and live steam Injector and fig. 5 is a section
on the line A-B fig. 4.

page_text: In fig. 1, a is a casing with flanges a¹ and a² by which the casing is combined with
the pipe conveying steam from a steam boiler or generator or source of supply to a
Steam Engine or Engines, or from a steam exhaust pipe to an exhaust steam Injector.
It will be seen that the casing a is divided into two chambers by a thin plate b of
metal which is or may be slided into grooves formed in the casing a and held therein
by a lid c, secured to flanges a³ on an opening giving access to the casing, or the plate b
is or may be secured by screws to the inside of the lid or cover c so as to be inserted
and removed with the lid or cover.
The steam flows in the direction shown by the arrows on fig. 1 and passes through
slits or holes formed in the plate (which may be of soft metal) by punching or
otherwise.
The metal round each hole or slit is made to project in front or beyond the general
face of the plate b to form a margin 6 round each hole or slit beyond the face of the
plate on one side of it-so that all liquid striking against that face of the plate b
will run down it by gravity and pass on the sides of the holes or slits 6¹ and not in
front of them so as to be carried through the holes or slits by the passing steam.
The liquid whether water or grease accumulates in front of the plate (the front
here means that side of the plate which the steam impinges upon before passing
through the holes or slits) and is conveyed away by a pipe e connected with any
ordinary and suitable "steam trap."
When the arrangement is used simply for separating water from steam passing
from a boiler to an Engine or Engines the water separated is or may be returned to
the water space of the boiler by connecting the pipe e with such water space
providing the casing a is sufficiently above the water space of the boiler to allow the
water separated to flow by gravity from the casing a to the water space of the boiler.
When the apparatus is used mainly for separating the grease from the steam,
then a steam trap arrangement above referred to is used, but when the
apparatus is used for separating the grease from that portion of exhaust steam
from an Engine or Engines, which is passed to and taken by an Exhaust steam
Injector, then such exhaust steain being at or near atmospheric pressure, or which by
the action of the exhaust Injector is a little below atmospheric pressure, the pipe e is
or may be made with a bend to retain sufficient water or grease in it at all times to
prevent the admission of air, but allow the grease or water to escape, when it has
accumulated to the given extent.
The outlet from this said pipe e with a bend is or may also be closed by a valve
allowing fluid to pass out but preventing its return.
That modification of my invention shown by fig. 2 will be readily understood from
the previous description of fig. 1-It shows two plates and 6x with holes or slits
each constructed as hereinbefore described in reference to fig. 1.
It will be seen that the holes or slits & in one plate bare arranged to come opposito
the blank space in the other plate b*.
A series of these plates 6 and 6x are or may be alternately arranged in like manner
if desired, and in some cases the holes or slits & in one plate may be opposite these in
the adjoining plate, but by preference not directly opposite but so that the holes or
slits in one plate will be directly opposite the space between the holes or slits b¹ in
the adjoining plate.
It will be seen that in fig. 2 the cover or plate c has a passage c¹ to convey the water
or grease from the chambers in front of each plate band 6x to the pipe e for conveying
it away as herein before explained.
The modification shown by fig. 3 is the same as that shown by fig. 1, except that
a throttle valve is combined with the casing, d is the spindle of the valve, d' the
disc, which fills or closes the passage when the valve is shut, a' the stuffing box for
the valve spindle.
Figs. 4 and 5 illustrate my invention, where the casing a for the water or grease
separator is combined with the casing f of an Exhaust steam or combined Exhaust and
supplementary live steam Injector Only a part of the Exhaust steam injector is
shown, which may be of the ordinary construction.

page_text: The casing a, plate b, and throttle valve d and d' are similar to that shown by
fig. 3, except that the casing a is modified to combine it with the casing f for tho
Exhaust steam Injector.
The flange a is joined with the pipe forming a junction with the exhaust pipe,
same as exhaust steam injectors are connected with the exhaust steam supply.
When a combined Exhaust and supplementary live steam injector is used, as
supposed in figs. 4, and 5, the casing a is formed with a branch a with which the
live or boilor steam pipe is connected, and this branch is prepared to receive the
double coned live steam nozzle -The end of the casing of the Exhaust steam
Injector is formed with a flange to act when secured to the casing a, as a lid or
cover (corresponding to c figs. 1, 2 and 3) to which the plate fl and pipe e for grease
or water is secured, the grease and water being conveyed away by the pipe e as
hereinbefore explained.
h is the exhaust steam nozzle of the injector, i part of the combining nozzle, i part
of the hinged flap, f2 the water branch of the Exhaust steam Injector.
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 claim is,
1. The construction and arrangement of a plate or plates or surfaces (b) with holes
or slits for the steam to pass through; such holes having projecting margins round
them, substantially as and for the purpose hereinbefore described and illustrated by
the drawings.
2. The combinations and arrangements of parts substantially as and for the purpose
hereinbefore described and illustrated by figs. 1, 2 and 3, and figs. 4 and 5 of the
drawings.
3. The combination of apparatus or arrangements with Exhaust or Exhaust and
supplementary live steam Injectors and with the Exhaust pipe of the steam Engine or
Engines for separating grease from that portion only of Exhaust steam from a steam
Engine or Engines which passes to the Exhaust steam Injector substantially as
hereinbefore described.
