Improvements in Apparatus for Separating Oil, Grease, or like
Extraneous Matter from Exhaust Steam.
We, JOHN GEORGE KINCAID, of Oakfield, Greenock, Renfrewshire, Engineer,
and WILLIAM CROCKATT, of 21, Hope Street, in the City of Glasgow, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus of the kind described in the Specification of
Letters Patent No. 12,784 of 1894, and designed for separating oil, grease or like
extraneous matter from exhaust steam on its passage from an engine to the con-
denser, instead of from the pumps to the boilers, thus keeping the condenser and
pumps as well as the boilers free of greasy deposit; and the present improvements
have for their object to provide means whereby the trapping of the oil or grease
better ensured than heretofore.
In lieu of or in addition to the helical vanes formed in the exhaust pipe or
casing leading to the condenser, as described in the specification above referred
to, we form therein a hollow cone or bell whose base is of larger diameter than the
inlet to the condenser, so that as the exhaust steam impinges thereon and partial
condensation takes place, the oily matter carried forward by the steam will be
thrown outwards and downwards and drip from the lower edge into the trap or
collector formed around the mouth or inlet to the condenser, ample area or room
for the passage of the steam round the lower edge of the cone being left between
the spiral vanes.
In a modification in which the helical vanes are entirely replaced by the cone
or bell the exhaust pipe or a trunk or casing forming part of its length is bulged
or widened to cowl-like form to permit of the use of a cone of diameter sufficient
to fully cover the condenser mouth or inlet while leaving ample space for the
passage of the steam between the exhaust pipe and cone and between the lower
edge of the latter and the condenser mouth which extends upwards into the
exhaust passage to form a deep annular trap or collector for the oil and water.
In another modification a hollow and approximately spherical chamber is fitted or
formed in the length of the exhaust pipe and has formed within it a deep bowl where-
into the exhaust pipe extends and the oily matter is deposited and collected whilst the
purified steam passes into the annular space around the bowl and down a continua-
tion of the exhaust pipe or direct into the condenser.
In a further modification the oil trap or collector is formed by breaking the
continuity of the exhaust pipe or interposing a trap in its length. One portion
of the length of the exhaust pipe is terminated in a chamber which serves as the
trap or collector for the oil or greasy matter whilst the continuation of the exhaust
pipe extends from a point in this chamber above the level of the collecting oil
and the termination of the first part of the pipe, so that the steam is deflected in
its course towards the condenser the ends of the exhaust pipe taking the form of
Touvre or baffle plates. This construction may be readily adapted to horizontal
exhaust pipes in which a chamber is formed to depend from a portion of the length

page_text: of the exhaust pipe, and baffle plates are formed in the pipe above to deflect the
exhaust downwards into the chamber and prevent its direct flow therefrom towards
the condenser.
In all the above modifications the bottom of the collector is connected to a
specially arranged filter through which the condensed steam is returned to be
condensed and any oil or greasy matter carried along with it efficiently trapped.

Improvements in Apparatus for Separating Oil, Grease, or like
-Extraneous Matter from Exhaust Steam.
9.1
We, JOHN GEORGE KINCAID, of Oakfield, Greenock, Renfrewshire, Engineer,
and WILLIAM CROCKATT, of 21, Hope Street, in the City of Glasgow, 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:-
This invention relates to apparatus of the kind described in the Specification of
: Letters Patent No. 12,784 of 1894, and designed for separating oil, grease or 'like
..extraneous matter from exhaust steam on its passage from an engine to the con-
denser, instead of from the pumps to the boilers, thus keeping the condenser and
pumps as well as the boilers free of greasy deposit; and the present improvements
have for their object to provide means whereby the trapping of the oil or grease is
better ensured than heretofore.
The invention is illustrated by the accompanying drawings, Figure 1 of which
illustrates one modification of the apparatus showing its connection with "the
exhaust pipe and condenser through the filter. Figures 2, 3 and 4 are 'modifications
of the improved apparatus.

In lieu of or in addition to the helical vanes formed in the 'exhaust pipe or
casing leading to the condenser, as described in the Specification above referred
to, we form therein a hollow cone or bell C¹ whose base is of larger diameter than
the inlet to the condenser B so that. as the exhaust steami impinges thereon and
partial condensation takes place, the oily matter carried forward by the steam will
be thrown outwards and downwards and drip from the lower edge of the cone C¹
into the trap or collector D formed around the mouth or inlet to the condenser,
ample area or room for the passage of the steam round the lower edge of the cone
being left between the spiral vanes.

In the modification illustrated by Figure 2 in which the helical vanes are
entirely replaced by the cone or bell C¹ the exhaust pipe A' or a 'trunk or casing
forming part of its length is bulged or widened to cowl-like form as at O to permit
of the use of a cone C¹ of diameter sufficient to fully cover the condenser mouth or
inlet while leaving ample space for the passage of the steam between the exhaust.
pipe A and cone C and between the lower edge of the latter and the condenser
mouth which extends upwards into the exhaust passage to form a deep annular
trap or collector 1) for the oil and water.
In another modification illustrated at: Figure 3 a hollow and approximately
spherical chamber P is fitted or formed in the length of the exhaust pipe A and
has. formed within it a deep bowl Q wherein to the exhaust pipe A extends and

page_text: the oily matter is deposited and collected whilst the purified steam passes into
the annular space around the bowl and down a continuation of the exhaust
pipe A or direct into the condenser.
In a further modification the oil trap or collector is formed by breaking the
continuity of the exhaust pipe A or interposing a trap in its length. One portion
of the length of the exhaust pipe A is terminated in a chamber which serves as
the trap or collector for the oil or greasy matter whilst the continuation of the
exhaust pipe A extends from a point in this chamber above the level of the
collecting oil and the termination of the first part of the pipe, so that the steam
is deflected in its course towards the condenser the ends of the exhaust pipe taking
the form of louvre or baffle plates. This construction may, as shown at Figure 4,
be readily adapted to horizontal exhaust pipes in which a chamber R is formed to
depend from a portion of the length of the exhaust pipe A, and baffle plates R¹
are formed in the pipe A above to deflect the exhaust downwards into the collector
chamber R and prevent its direct flow therefrom towards the condenser B.
In all the above modifications the bottom of the collector D is connected to a
specially arranged filter S through which the condensed steam is automatically
returned to the condenser B and any oil or greasy matter carried along with it
efficiently trapped.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. As means for separating oil, grease or other extraneous matter from exhaust
steam a combined helical vane and cone, or a simple cone or like deflector fitted in
an exhaust pipe in combination with a trap or collector formed therein, this
collector being connected to a filter which retains the oil and greasy matter and
passes the condensed steam to condenser substantially as described.
2. The improved apparatus for separating oil, grease or other extraneous matter
from exhaust steam, constructed substantially as described with reference to
Figure 1 of the annexed drawings.
3. The improved apparatus for separating oil, grease or other extraneous matter
from exhaust steam, constructed substantially as described with reference to
Figure 2 of the annexed drawings.
4. The improved apparatus for separating oil, grease or other extraneous matter
from exhaust steam, constructed substantially as described with reference to
Figure 3 of the annexed drawings.
5. The improved apparatus for separating oil, grease or other extraneous matter
from exhaust steam, constructed substantially as described with reference to
Figure 4 of the annexed drawings.
