PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Purifying Water or other Liquids.
I RICHARD SYDNEY BROWNLOW of Canning Works Manchester in the County
of Lancaster, Filter Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates chiefly to the purification of water by the action of
chemical or other re-agents which cause the precipitation in a solid or flocculent
form of the impurities contained therein, but it is also applicable to the purification
of other liquids containing precipitable matter.
The invention consists of certain improvements on or modifications of the inven-
tion for which Letters Patent No. 16006 dated October 9th 1890 were granted to
me, the object being to increase the efficiency of such apparatus principally by
reducing the distance to which the water or liquid has to travel on its passage
through the apparatus and by thus obtaining a reduced amount of movement the
water is more tranquil or stagnant and hence the precipitation takes place more
readily and speedily.
According to the first part of my present improvements I dispense with the
bafflers or plates marked d on the drawings annexed to the Specification of the
Letters Patent above mentioned so that the water or liquid in passing round the mid-
feather takes a straighter course.
As a second modification I propose in some cases to dispense also with the mid-
feather 6 and to substitute therefor small triangular baffle-plates between the inclined
plates c and c¹.
As a third modification I propose to retain the midfeather b¨but instead of its
being a solid plate, to perforate the same either at the central part only or all
over, so that the water or liquid can pass through, instead of round the outside of,
the said midfeather, and in this case I propose sometimes to prevent the water or
liquid from taking too direct an upward course by fixing narrow baffle plates on
alternate sides of the said perforated midfeather.
And as a fourth modification or improvement I propose instead of perforating the
mid feather as last above described to perforate the same on alternate sides only,
that is to say, in the compartment formed by or between the first and second inclined
plates 1 perforate the midfeather (say) on the right hand side only, and in the
next compartment formed by or between the second and third inclined plates I
perforate the midfeather at the left hand side only, and so on alternately, small
baffle plates being placed at an angle with the midfeather, if desired to make the
water take a more serpentine course.

10 Improvements in Apparatus for Purifying Water or other Liquids.
I, RICHARD SYDNEY BROWNLOW of Canning Works Manchester in the County
of Lancaster Filter Manufacturer 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 chiefly to the purification of water by the action of

page_text: chemical or other re-agents which cause the precipitation in a solid or flocculent
form of the impurities contained therein, but it is also applicable to the purification
of other liquids containing precipitable matter.
The invention consists of certain improvements on or modifications of the inven-
tion for which Letters Patent No. 16006 dated September 9th 1890 were granted
to me, the object being to increase the efficiency of such apparatus principally by
-reducing the distance through which the water or liquid has to travel on its passage
through the apparatus and, by thus obtaining a reduced amount of movement, the
water is more tranquil or stagnant, and hence the precipitation takes place more
readily and speedily.
According to the first part of my present improvements I dispense with the
bafflers, or plates marked d (see Fig. 3) on the drawings annexed to the Specifi-
cation of the Letters Patent above named so that the water or liquid in passing
round the midfeather 6 takes a straighter course, as shown on Fig. 1 of the drawings
hereunto annexed.
As a second modification I propose in some cases to dispense also with the mid-
feather and to substitute therefor triangular baffle-plates between the inclined
plates & and c² leaving trapezoidal spaces at alternate sides of the chamber, see
Fig. 2 of the annexed drawings. Or if the plates intersect the trapezoidal spaces
may be dispensed with.
As a third modification I propose to retain the midfeather b, but instead of its
being a solid plate, to perforate the same (see Fig. 3 of the annexed drawings)
either at the central part only or all over so that the water or liquid can pass
through instead of round, the outside of the said midfeather, which is made the
whole width of the casing a instead of being narrower as before; and in this-case
I propose sometimes to prevent the water or liquid from taking too direct an
upward course by employing the baffle plates d, which may be placed either vertically
or horizontally.
And as a further modification or improvement propose, instead of perforating
the midfeather as last above described, to perforate the same on alternate sides
only that is to say, in the compartment formed by or between the first and second
inclined plates I perforate the midfeather (say) ou the right hand side only, and
in the next compartment formed by or between the second and third inclined
plates I perforate the midfeather at the left hand side only, and so on alternately,
small baffle plates being placed at an angle with the midfeather, if desired, to
make the water take a more serpentine course.
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 :-
The various modifications of my water purifying apparatus, substantially as herein
before described and illustrated by the annexed drawings.
