Improvements in Means for Extracting or Separating the Water
from Steam in Steam Pipes.
We WILLIAM DURANT of Thorncliffe Lane, Chapeltown near Sheffield in the
County of York, Electrician and THOMAS WILLIAM BARON DURANT of Thorncliffe
Lane, Chapeltown aforesaid Electrician 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 means for extracting or separating collecting and
removing water from steam in pipes for conveying steam from generators to motors
and the object thereof is to arrange a simple and efficient mechanical separator and
collector whereby the water which would otherwise pass with the steam to the
motor and so reduce the effeciency thereof is previously collected and withdrawn
thereby permitting the steam to proceed and perform its work in a drier state than
has hitherto been possible to secure.
To attain which we construct and arrange a mechanical device substantially as set
forth in the accompanying drawings which are to be taken as typical illustrations
thereof but not as final forms as it will be obvious that the device may be modified to
suit various sizes shapes and forms of pipes without departing from the essential
particulars of our invention.
Fig. 1. is a longitudinal sectional elevation of our improved means applied to an
arrangement of ordinary steam piping and
Fig. 2. is an isometric perspective view of the grating employed in our improved
device and
Fig. 3 is an end view of our improved device or length of piping with our improved
device combined.
Figs. 4, 5, 6 and 7 are cross sectional elevations which would be taken on line a a
of Fig. 1. of modified forms of our improved device.
Similar letters of reference denote corresponding parts in each view. We arrange
a length of steam piping B with flanges & suitable to couple up to the ordinary
steam piping C in the usual way, and the lower part of the said piping B is arranged
in the form of a tapered or wedge shape chamber 62 the depth of which increases
in the direction of the flow of the steam as shown by arrows.
The upper part of the tapered chamber 62 is preferably formed with a ledge or
beading whereon rests an especially formed iron metal or other plate D which is
formed with rectangular perforations d' and projections de running longitudinally
with and so situated as to occupy the complete cross section area of said plate, the
majority of said projections leaning against the motion of the steam towards the
narrowing direction of the chamber and the remainder leaning in the opposite
direction as shown Figs. 1 and 2.
The upper inner side of pipe B at the inflowing end is preferably formed with a
deflecting internal projection see Fig. 1.
The lower part of chamber 2 is in the form of a branch 6 and receives a piece of
water piping & with a tap b'.
As the steam and water travel in the direction of the arrows within the pipe B
the water comes in contact with the projections d2 and is conducted through the
perforations d and the reversing of the directions of the projections d¹ near the
exit end of pipe B facilitates the egress of any steam that may flow with the water
through the perforations and prevents the return of the water as will be well
understood

page_text: As the water is collected in the chamber 62 it flows down the branch and out of
the water piping and tap.
Should water be suspended in the steam as it enters the pipe B it is deflected
on to the grating or plate D by the tapered projection 6.
We do not confine ourselves to any special form of plate D although by experi-
ment we have found that shown at Figs. 1, 2 and 3 to give excellent results but the
various forms shown at Figs. 4 to 7 and arranged with or without projections may
be employed and likewise an ordinary grating or a series of bars may be employed.
Fig. 4. shows a V form of grating or plate D with projections and perforations.
Fig. 5. shows a flat plate 1) with perforations and no projections.
Fig. 6. shows a corrugated plate D with projections and perforations.
Fig. 7. shows a curved plate D with projections and perforations.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In means for extracting or separating the water from steam in pipes used for
the conveyance of steam; the combination in a pipe B of a tapered or other
chamber with a plate D having perforations d' and with or without projections d
and a deflector substantially as described and illustrated in the accompanying
drawings or any mere obvious modification of said combination.
