Improvements in Apparatus for Separating Liquids from Solid
Matters Suspended therein.
We JOHN SHEPHERD SAWREY of No. 53 Carleton Road, Tufnell Park, Middlesex,
Engineer, and HAROLD COLLET of 7 Coleridge Road, Finsbury Park, Middlesex,
Engineer do hereby declare the nature of this invention to be as follows:-
Our invention relates to apparatus through which liquids are passed for the purpose
of inducing the solid matters suspended therein to settle out by gravitation, provision
being made for drawing off the deposit or solid matter through escape cocks. For
this purpose we place in such apparatus a number of parallel flat or corrugated plates
set perfectly vertical and without angles from the vertical, so that no portion of any
plate shall incline at an angle from the perpendicular. The liquid is made to pass
between the said plates, below which is a coned or shelving bottom or receptacle
leading to a mud cock by means of which the deposit may be drawn off.

For
Our invention relates to apparatus through which liquids are passed for the purpose
of inducing the solid matters suspended therein to seitle out by gravitation, provision
being made for drawing off the deposit or solid matter through escape cocks.
this purpose we place in such apparatus a number of parallel flat or corrugated plates
set perfectly vertical and without any angles from the vertical, so that no portion of
any plate shall incline at an angle from the perpendicular. The liquid is made to pass
either upwards. downwards or horizontally between the said plates, and while passing
between them the solid particles touch and are detained by the plates and thence slide
down to a coned or shelving bottom or receptacle leading to a mud cock by means of
which the deposit may be drawn off.
Referring to the drawings, Figs. 1 and 2 shew a vertical tank provided with a set
of vertical Hat plates (shewn in plan in Fig. 3). The plates are shewn at the bottom
of the tank extending only a short distance up, but they may be at the top or middle
of the tank and may be of any height desired. The water may pass either from the
top downwards or from the bottom upwards, or it may be introduced on a level with
the plates and pass horizontally between them; in the latter case the plates are
preferably corrugated as in Fig. 4. The direction of the corrugations is in all cases
such that a perpendicular section of any plate shall be a straight vertical line, and we
make no claim to the use of plates in which the corrugations make an angle from the
vertical.
Having now particularly described and ascertained the nature of our said inven-
Lion and in whit manner the same is to be performed, we declare that what we
claim is :-
In apparatus for the purpose herein described the use of vertical depositing or
baffle plates substantially as described and for the purpose set forth.
