Improvements in Steam Traps or Separators.
I JOHANN KLEIN, of Frankenthal, Rhine Province, Empire of Germany,
Manufacturing Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in steam traps or separators in which the
discharge of condensed water is regulated by the rise and fall of a floating vessel
arranged to operate a valve opening and closing communication between the
floating vessel and the discharge pipe.
Upon the accompanying drawing representing a vertical section of my improved
steam trap or separator the casing of the apparatus is formed of two parts A
and B, of which the lower part A is provided with a mud-hole D to permit of
the removal of deposits or impurities. The upper part B comprises in one casting
a steam inlet passage b, the water discharge passage c with valve-box G of valve v,
and vertical piped communicating through valve passages and i with an
outlet c when the valve at its upper end is open, and with the interior of the
floating vessel C at its lower extremity. The floating vessel C is movable upon
the vertical pipe d and a valve rod s fixed to the bottom of the vessel extends
upwards through the pipe d and is connected at its upper end with the valve v.
To prevent the direct influx of the water of condensation from the inlet b into
the floating vessel C, the inner end of the inlet passage is arranged at a lower level
than the entrance, and is partially closed by a partition w extending across it and
formed in a piece with the upper part B of the casing as shewn, or by any known
equivalent device. The casing of the valve-box G is so constructed that the
interior of the floating vessel C is separated from the outlet c by the insertion of a
hollow screwed plug 9 within the upper end of the vertical pipe d, whilst the outlet c
is also closed to the outer air by means of a flange g¹ provided with a suitable
washer which can be tightened up by screwing the plug g. By this arrangement
of the valve-box therefore a double closure is obtained.
g
Within the valve-box G are provided lateral perforations i, and a vertical
passage, which can be shut off by the valve v, so that by the rising and falling of
the floating vessel C, communication with the outlet c and the interior of the vessel
is alternately opened and closed at short intervals.
The floating vessel C which is provided with perforations e near its upper edge
operates as follows :-
The water of condensation entering by the inlet b, in the direction indicated by
the arrow, partially fills the space surrounding the floating vessel C which by
reason of its buoyancy rises until the valve rods having closed the valve v against
the passage arrests the upward movement of the vessel. When the water level
reaches the height of the perforations e near the upper edge of the floating vessel C,
it flows through these perforations into the interior of the vessel and ascends within
the vertical pipe d until the buoyancy of the floating vessel C is destroyed by the
super-added weight of the inflowing water whereupon the vessel descends sufficiently
to open the valve by means of the rod s. The accumulated water of condensation
will then be forced out by the steam pressure within the floating vessel C, through the
vertical pipe d, passage, and discharge outlet c. This action is repeated inter-
mittently at very short intervals so that the constantly accumulating quantities of
water are discharged in an approximately continuous manner.

of the casing as shewn.
By the above described arrangement the construction of the condensing vessel
is considerably simplified, and the advantage is obtained by the central division of
the valve-box of so placing the packing within a groove as to render it capable of
withstanding a very high pressure. Moreover the arrangement of the mud-hole D
in the lower part A of the casing permits of the cleaning of the trap without
necessitating its disconnection.

Improvements in Steam Traps or Separators.
I, JOHANN KLEIN, of Frankenthal, Rhine Province, Empire of Germany,
Manufacturing Engineer, do hereby declare the nature of this invention to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in steam traps or separators in which the
discharge of condensed water is regulated by the rise and fall of a floating vessel
arranged to operate a valve opening and closing communication between the
floating vessel and the discharge pipe.
Upon the drawing filed with my Provisional Specification, representing a
vertical section of my improved steam trap or separator the casing of the
apparatus is formed of two parts A and B, of which the lower part A is provided
with a mud-hole D to permit of the removal of deposits or impurities. The upper
part B comprises in one casting a steam inlet passage b, the water discharge
passage with valve box G of valve v, and vertical pipe d communicating through
valve passages and with an outlet c when the valve at its upper end is open,
and with the interior of the floating vessel C at its lower extremity. The floating
vessel C is movable upon the vertical pipe d and a valve rod s-fixed to the bottom
of the vessel extends upwards through the pipe d and is connected at its upper end
with the valve v.
To prevent the direct influx of the water of condensation from the inlet b into
the floating vessel C, the inner end of the inlet passage is arranged at a lower level
than the entrance, and is partially closed by a partition w extending across it and
formed in a piece with the upper part B of the casing as shewn, or by any known
equivalent device. The casing of the valve-box G is so constructed that the
interior of the floating vessel C is separated from the outlet c by the insertion of a
hollow screwed plug g within the upper end of the vertical pipe d, whilst the
outlet c is also closed to the outer air by means of a flange g provided with a
suitable washer which can be tightened up by screwing the plug g. By this
arrangement of the valve-box therefore a double closure is obtained.
Within the valve-box G are provided lateral perforations i, and a vertical
passage, which can be shut off by the valve v, so that by the rising and falling of
the floating vessel C communication with the outlet c and the interior of the vessel
is alternately opened and closed at short intervals.
The floating vessel C which is provided with perforations e near its upper edge
operates as follows:-
The water of condensation entering by the inlet bin the direction indicated by
the arrow, partially fills the space surrounding the floating vessel C which by
reason of its buoyancy rises until the valve rod s having closed. the valve o against
the passage arrests the upward movement of the vessel. When the water level

page_text: reaches the height of the perforations e near the upper edge of the floating
vessel C, it flows through these perforations into the interior of the vessel and
ascends within the vertical pipe à until the buoyancy of the floating vessel C is
destroyed by the super-added weight of the inflowing water whereupon the vessel
The accumu-
descends sufficiently to open the valve by means of the rod s.
lated water of condensation will then be forced out by the steam pressure within
the floating vessel C through the vertical pipe d, passage, and discharge
outlet c. This action is repeated intermittingly at very short intervals so that
the constantly accumulating quantities of water are discharged in an approximately
continuous manner.
A draw-off tap a may be provided in a convenient position on the lower part A
of the casing as shewn.
By the above described arrangement the construction of the condensing vessel
is considerably simplified and the advantage is obtained by the central division
of the valve-box of so placing the packing within a groove as to render it
capable of withstanding a very high pressure. Moreover the arrangement of
the mud-hole D in the lower part A of the casing permits of the cleaning of
the trap without necessitating its disconnection.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In steam traps or separators, in which the discharge of the water is controlled
by means of a float, a centrally divided casing, the lower part of which is provided
with 'mud-hole or cleaning outlet D, and the upper part with steam inlet
passage band water discharge outlet c, together with the valve-box G and vertical
pipe d, constructed combined and arranged as and for the purposes described
and illustrated upon the drawings filed with my Provisional Specification.
