The Separation of Steam or other Vapours or Gases from Liquids
Mixed with them.
I, JEREMIAH EUGENE MATHEWSON, 265 Upperthorpe Sheffield, in the County of
York, Engineer do hereby declare the nature of this invention to be as follows:-
Various plans have heretofore been proposed for doing this by giving a rapid
rotation to a current of the mixed gas & liquid, whereby the liquid portion is thrown
to the circumference by the centrifugal force, while the purified gas or steam is drawn
from the centre.
My invention consists in causing the rotary motion of the mixed gas and liquid to take
place in a tube pierced with numerous small holes, and surrounded by another tube,
with a space between them, the effect of which is that the liquid thrown outward by
the centrifugal force will pass through the perforated walls of the inner tube, & will
collect in the space between the tubes, and can be drawn off by any convenient means,
while the purified steam or gas passes on. The rotary motion can be given to the
mixture of gas and liquid in any convenient way.
A screw or spiral partition may be fitted into a straight perforated tube, or the
perforated tube may be made in the form of a cork-screw, and the current of mixed
gas and liquid introduced at one end, and as it is whirled round in the spiral passage
or passages, it gradually throws off the liquid through the perforations and becomes
purified by the time it reaches the other end.
The perforated tube may be made conical so that the centrifugal force will become
greater towards the small end.
The size of the perforations may be made gradually smaller towards the exit end.
By the expression "perforated tube," I mean a tube pierced with numerous holes,
made of wire gauze, perforated sheet metal or otherwise.

Mixed with them.
I, JEREMIAH EUGENE MATHEWSON Bellefield Works, Sheffield, in the County of
York, 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 :-
My invention relates to the separation of steam or other vapours or gases from
liquids mixed with them.
I am aware that various plans have heretofore been proposed for doing this by
giving a rapid rotation to a current of the mixed gas and liquid, (such as that of
Dundonald, a description of which is published in Spons Dictionary of Engineering
of 1871, under the heading of "Boilers" pages 433-4) whereby the liquid portion is
thrown to the circumference by the centrifugal force, while the purified gas or steam
is drawn from the centre; and therefore I do not claim such principle.
I have therefore illustrated my invention in the annexed sheet of drawings, which
show a sectional elevation, of an Apparatus made according to my invention.
My invention consists in causing a rotary or spiral motion of the mixed gas or
steam and liquid to take place in a perforated tube B, surrounded by another tube or
casing A, so as to leave a space between them, the effect being that the liquid is
thrown outward by centrifugal force, and passing through the perforated walls of the
inner tube B, will collect in the space between the tubes, from which it can be drawn
off by any convenient means, such as shown at G, while the purified Steam or gas
passes on.
The rotary or spiral motion, can be given to the mixture of gas and liquid in any
convenient way, for example a screw or spiral partition F, may be fitted into the lower
part E, or completely through the perforated tube B, or the perforated tube may be
made in the form of a coil or corkscrew, the current of mixed gas and liquid being
introduced at one end, (as at F) and as it is whirled round in the spiral passage, or
passages F, it gradually throws off the liquid through the perforations C, or D, and
becomes purified by the time it reaches the other end.
Any steam which may escape with the water through the perforations, rises and
joins the main current again at the upper end of the perforated tube as indicated by
the arrows.
The rotary or spiral motion may be given to the mixture in the perforated tube, by
the rapid rotation of a central spindle carrying one or more vanes and driven by any
convenient means.
By the expression "perforated tube," I mean a tube pierced with numerous holes,
such as C, or D; or other shapes or made of wire gauze, perforated sheet metal, or
otherwise.

page_text: 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 separation of Steam, or other vapours or gases, from liquids mixed with
them, by causing (by any suitable means) a rotary or spiral motion of the said mixture
to take place in a perforated tube, for the purpose herein before specified.
2 An Apparatus for separating Liquids mixed with Steam, or other vapours or
gases, substantially as hereinbefore described and illustrated.
3-In a Separator, for the purpose herein before specified, the combination of a
perforated tube, with one or more spirally formed passages, leading to or passing
through the said tube, substantially as hereinbefore described.
J. E. MATHEWSON.
