page_text: An Improved Appliance for Discharging Condensation Water.
I, EMANUEL BLAUHORN, of III Barichgasse 5A, Vienna, Austria, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an appliance for the elimination of condensation water
which permits such water to continuously flow away. It consists of a piston or plug
accurately fitted into a casing connected with the steam duct; this plug has channels
running round it through which the condensation water can find exit, while the steam
is prevented from issuing on account of the water-packing formed by the condensation
of the steam in the channels.
The accompanying drawings shew various forms of my discharging appliance in
vertical section.
Fig. 1 shews an arrangement with a fixed plug or piston on which are formed the
channels.
Fig. 2 shews an arrangement also with a fixed plug but with the channels formed
in the casing.
Figs. 3 and 4 shew arrangements analogous to that of Fig. 1 combined respectively
with a valve for letting off condensation water, and with a cut-off cock.
Fig. 5 shews a plug consisting of several concentric parts provided with channels,
and Fig. 6 a plug combined with a valve.
At the lowest point of the steam duct is fixed a casing g g¹ in the upper part of
which the condensation water can collect.
In the cylindrical portion of this casing a metal plug or piston k is accurately
fitted but without much friction, so that it can be moved easily in the casing.
As shewn in Fig. 1, this plug has channels r in its surface which may be of
various forms and have various inclinations to the axis of the plug; preferably,
however, they are arranged vertically to the direction of flow of the condensation
water. At its lower end the plug is provided with the transverse passage o and an
axial bore communicating therewith. To prevent the plug from falling out it can
be fixed in the casing by the screw bor in some other manner.
In the form shown in Fig. 2, the channels are formed in the inner wall of the
cylindrical casing g; instead of the bore l a side exit tube is used and the fixing of
the plug in its casing is effected by a plate and flange.
Fig. 3 shews a plug fixed by a screw and provided with channels, and having
a central opening for a valve v, such as are used in steam heating pipes, the spindle
of which passes through the bore l.
Fig. 4 is of the same form, viz. a plug provided with channels, but is combined
with a cut off cock h.
The plug can also be made movable in the casing and can be subjected to the
pressure of the steam on the one hand and the pressure of a spring on the other
hand, as shewn in Figs. 5 and 6. By this movement of the plug the settling of
dirt between the plug and the casing will be prevented.
The action of the appliance is, in all its forms, as follows:-As the plug is not
absolutely tight, the condensation water which forms above it can be expressed into

page_text: the open air between the plug and the casing.
When no condensation water
is present, the steam seeks an exit by this way, but condenses in the channels and
escapes in the form of drops of water into the open air. The channels rr, when
filled with water, form a tight packing and practically close the plug steam-tight
so that escape of steam, even at high pressure cannot occur.
I, EMANUEL BLAUHORN, of III Barichgasse 5A, Vienna, Austria, 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 an appliance for the elimination of condensation water
which permits such water to continuously flow away. It consists of a piston or plug
accurately fitted into a casing connected with the steam duct; this plug has channels
running round it through which the condensation water can find exit, while the
steam is prevented from issuing on account of the water-packing formed by the
condensation of the steam in the channels.
The drawings accompanying my Provisional Specification shew various forms of my
discharging appliance in vertical section.
Fig. 1 shews an arrangement with a fixed plug or piston on which are formed the
channels.
Fig. 2 shews an arrangement also with a fixed plug but with the channels formed
in the casing.
Figs. 3 and 4 shew arrangements analogous to that of Fig. 1 combined respectively
with a valve for letting off condensation water, and with a cut-off cock.
Fig. 5 shews a plug consisting of several concentric parts provided with channels,
and Fig. 6 a plug combined with a valve.
At the lowest point of the steam duct is fixed a casing g g¹ in the upper part of

As shewn in Fig. 1, this plug has channels in its surface which may be of various
forins and have various inclinations to the axis of the plug; preferably, however
they are arranged vertically to the direction of flow of the condensation water.
its lower end the plug is provided with the transverse passage o and an axial bore
communicating therewith. To prevent the plug from falling out it can be fixed in
the casing by the screw b or in some other manner.
In the form shewn in Fig. 2, the channels are formed in the inner wall of the
cylindrical casing g; instead of the bore la side exit tube l'is used and the fixing
of the plug in its casing is effected by a plate and flange.
Fig. 3 shews a plug fixed by a screw and provided with channels, and having a
central opening for a valve v, such as are used in steam heating pipes, the spindle o
which passes through the bore l.
Fig. 4 is of the same form, viz. a plug provided with channels, but is combined
with a cut off cock h. The plug k can also be made movable in the casing, and car
be subjected to the pressure of the steam on the one hand and the pressure of

page_text: spring on the other hand, as shewn in Figs. 5 and 6. By this movement of the plug
the settling of dirt between the plug and the casing will be prevented.
The action of the appliance is, in all its forms, as follows:-As the plug is not
absolutely tight, the condensation water which forms above it can be expressed into
the open air between the plug and the casing. When no condensation water is pre-
sent, the steam seeks an exit by this way, but condenses in the channels and escapes
in the form of drops of water into the open air.
The channels 'r, when filled with water, form a tight packing and practically
close the plug steam-tight so that escape of steam, even at high pressure cannot
occur.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is
1. Appliance for discharging condensation-water consisting of a casing connected
to the steam conduit and containing a piston or plug which closes the casing against
the outer air and which has annular grooves formed round it, that allow the
condensation-water collecting in the casing to gradually descend between it and the
piston so as to escape into the outer air while preventing the escape of steam,
substantially as described.
2. In an appliance for discharging condensation-water such as is referred to in
the first claim, arranging the grooved piston or plug movable and combining
therewith a spring acting in opposition to the pressure of the steam, substantially as
described.
3. In an appliance for discharging condensation-water such as is referred to in the
first and second claims, forming-the annular grooves r that serves for the discharge
of the condensation water in the walls of the casing g surrounding the piston,
substantially as described.
