Improvements in Apparatus for Separating Grit, Water, Oil, or
Grease from Steam or other Liquids.
I, ROBERT DAWSON, of Park Hill, Stalybridge, in the County of Chester,
Heating Engineer, do hereby declare the nature of this invention to be as follows:
11
This invention is.primarily designed for arresting foreign matter such as scale
iron chips red lead or other grit or water that may be carried along with live steam
or for separating oil grease grit or the like from exhaust steam before such is passed
into or enters a steam trap.
The apparatus is constructed with a vertical division plate and a horizontal
separator plate. The division plate extends down towards the bottom of the
apparatus with sufficient space below it for the steam to pass round it and allow of
the impurities to collect below it. The separator plate extends horizontally across
the apparatus and is provided with perforations those at the side at which the
steam enters being preferably larger than those at the outlet side.
Where the apparatus is intended for separating water or oil from steam it may
also be provided with a second chamber and a false or perforated bottom to prevent
the steam coming again in contact with the water or oil or prevent any current
that may be passing through the apparatus from agitating it.
The outlet pipe may also be fitted with a steel sleeve to prevent water which
may be formed by the steam condensing on the sides of the chamber from escaping
up into the outlet as such water of condensation will drop back from the lower
edge.
A plug or blow-off pipe is fitted to the bottom of the apparatus which can be
opened at any time to remove the impurities which have collected in the bottom.
This separator apparatus is also applicable for use with pumps elevator engines
water meters bleaching kiers or other apparatus operated by fluids or liquids.

Improvements in Apparatus for Separating Grit, Water, Oil, or

I, ROBERT DAWSON, of Park Hill, Stalybridge, in the County of Chester,
Heating 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 is primarily designed for arresting foreign matter such as scale
iron chips red lead or other grit or water that may be carried along with live-
steam or for separating oil grease grit or the like from exhaust steam before such
is passed into or enters a steam trap.
It consists essentially of apparatus constructed with two upper and one lower
chambers provided with a vertical division plate attached to a perforated horizontal

page_text: separator plate so placed that the steam enters at one side of the vertical division
plate by which it is deflected downwards through one side of the perforated plate
into the lower chamber passing upwards again through the other side of the
horizontal perforated plate and at the other side of the vertical plate.
The invention will be fully described with reference to the accompanying drawings
in which two modifications are shown.
separator plate so placed that the steam enters at one side of the vertical division
plate by which it is deflected downwards through one side of the perforated plate
into the lower chamber passing upwards again through the other side of the
horizontal perforated plate and at the other side of the vertical plate.
The invention will be fully described with reference to the accompanying drawings
in which two modifications are shown.

The apparatus is formed of a casting A. with a vertical division plate B and a
perforated horizontal separator plate C dividing it into three chambers two upper
chambers a a¹ and a lower chamber at a steam inlet orifice D being provided in
the chamber a and the outlet E in the chamber a'. The division plate B extends
down towards the bottom of the apparatus with sufficient space below it in the
chamber all for the steam to pass round it and allow of the impurities to collect
below it. The separator plate C extends horizontally across the apparatus and is
provided with perforations c c¹ the perforations c at the side at which the steam
enters being preferably larger than those at the outlet side.
Referring to Figs. 1 to 4 where the apparatus is intended for separating water
or oil from steam it may also be provided with another chamber at placed at the
bottom and a false or perforated bottom or drip plate F to prevent the steam
coming again in contact with the water or oil or prevent any current that may be
passing through the apparatus from agitating it.
The outlet pipe E may also be fitted with a steel sleeve G of funnel shape to
prevent water which may be formed by the steam condensing on the sides of
the chamber from creeping up into the outlet as such water of condensation will
drop back from the lower edge.
A plug or blow off pipe is fitted to the bottom of the apparatus which can be
opened at any time to remove the impurities which have collected in the bottom.
This separator apparatus is also applicable for use with pumps elevator engines
water meters bleaching kiers or other apparatus operated by fluids or liquids.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
Apparatus for separating grit, oil, or grease from stean or other liquids con-
structed with a vertical deflecting plate and a perforated horizontal separating
plate dividing it into three chambers or compartments with or without a perforated
bottom or drip plate substantially as described and shown.
