PROVISIONAL SPECIFICATION:
Improvements in Purifiers applicable for Steam Boilers and other
purposes.
I, JOHN EDWARD SLACK, of Chester Road, Manchester, in the County of
Lancaster, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:--
This invention relates to improvements in purifiers used for separating impuri-
ties or solids contained in feed water or other liquids.
In the present construction of purifiers where a number of diaphragms or
baffle plates are employed to form a number of settling chambers the diaphragms
or baffle plates are usually fixtures or are only movable by obtaining direct access
to them and in order to clear out the purifier under pressure when in use it is
necessary to provide blow-off outlets for each chamber.
My invention consists essentially in constructing the purifier with the dia-
phragms or baffle plates which divide it into or form the settling chambers
attached to a central rod bar or spindle capable of being turned about its axis
and so lift or remove the plates out of contact with the bottom of the purifier to
permit. of it being blown off through a single outlet when in use and under
pressure.
In carrying out this invention these diaphragms are secured to or rest upon a
rod bar or spindle placed inside a cylindrical chamber of the purifier.
This bar rod or spindle or an attachment to it extends through the casing of
the purifier and is fitted with a lever of suitable form by which it can be moved
thus causing the diaphragms or baffle-plates to move at the same time. The
position of the diaphragms or baffle-plates can thus be reversed thus leaving the
bottom of the chamber in which they are suspended free from end to end for
cleansing purposes.
With the position of the diaphragms reversed the solids or impurities can be
forced out under pressure through one outlet only and this without putting the
purifier out of working order.
By removing the end plate all the diaphragms or baffle-plates can be drawn
cut as one piece to afford facility for inspection and cleansing when the purifier
is out of use.

Improvements in Purifiers applicable for Steam Boilers and other
purposes.
I, JOHN EDWARD SLACK, of Chester Road, Manchester, in the County of
Lancaster, Mechanical 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 relates to improvements in purifiers used for separating impuri-
ties or solids contained in feed water or other liquids.
In the present construction of purifiers where a number of diaphragms or
baffle plates are employed to form a number of settling chambers the diaphragms
or baffle plates are usually fixtures or are only movable by obtaining direct access
to them and in order to clear out the purifier under pressure or when in use it is
necessary to provide blow-off outlets for each chamber.
My invention consists essentially in constructing the purifier with the dia-
phragms or baffle plates which divide it into or form the settling chambers
attached to a central rod bar or spindle capable of being turned about its axis
and so lift or remove the plates out of contact with the bottom of the purifier to
permit of it being blown off through a single outlet when in use and under
pressure.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Longitudinal section.
Fig. 2. Transverse section through line - Fig. 1.
Fig. 3. Transverse section through line y-y Fig. 1.
The purifier is constructed of the ordinary cylindrical shell A divided into
settling chambers or compartments B by the diaphragms or plates C.
The diaphragm or plates C are not attached to the sides A of the purifier but
are attached to a rod or staff D extending longitudinally of the purifier. The rod
or shaft D (or an extension of it) extends through one or both ends of the purifier
and is fitted with a hand wheel E or lever of any suitable form by which it can
be rotated.
The diaphragms or plates are of such a shape that a space or opening e is left
above them and under each alternate one a space b is left at the bottom.
In a modification if desired the short plates with the space below may be
fitted to the sides of the purifier and the other alternate plates attached to the rod
or shaft D but I at present prefer the arrangement in which all the diaphragms
or plates C are attached to the rod or shaft D.
F is the steam inlet, G the water inlet, K the water outlet and H the blow off
pipe.
By rotating the rod or shaft D the diaphragms or plates C are lifted or removed
at the same time their position being reversed from the bottom to the top of the
purifier thus leaving the bottom of the chamber in which they are suspended free
from end to end for cleaning purposes.
With the position of the diaphragms reversed the solids or impurities can be
forced out under pressure through one outlet only at H and this without putting
the purifier out of working order.
By removing the end plate all the diaphragms or plates C can be drawn out as
one piece to afford facility for inspection and cleansing when the purifier is out
of use.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A purifier for feed water or other liquids constructed with the internal
diaphragms or plates attached to a rod or shaft by the rotation of which they can
be raised or removed for the purpose of clearing or removing sediment sub-
stantially as described.
2. A purifier for feed water and other liquids constructed and arranged sub-
stantially as and for the purpose described.
