I ANDREW HOWATSON of 7 Lavender Hill, Surrey, Engineer do hereby declaro
the nature of my said invention to be as follows:-
This invention relates to certain novel detail methods of arranging plates or
appliances in vessels of any suitable shape but preferably in vessels that shall
correspond in shape or approximately so to suit the position or arrangement of the
plates for the purpose of separating solid or flocculent impurities from water or
other liquids which is or are passed upwards through the apparatus said upflow or
passage being uniform or otherwise according to the nature of the liquid under
operation.
The invention is based upon a previous patent applied for by me on the
23rd May 1885 No. 6351 in the specification of which Letters Patent reference is
made to the employment of corrugated, fluted or zig zag plates arranged vertically
within a vessel and having between said plates a series of corresponding passages
all tending upwards but deviating alternately from side to side said passages being
for the upflow of liquid from the lower part of the vessel this forming a receptacle
in which the solid matter deposits itself after sliding down from said plates the
clear water flowing away from the upper part of said vessel in any convenient
manner.
Now according to my present invention I employ flat plates set out of the
perpendicular or at an angle or angled plates can be set vertically the angles being
of the same or of different lengths or corrugated plates may be set at an angle
with their corrugations running vertically or otherwise or other equivalent forms
of plates can be arranged within a vessel which may be upright or arranged with
sides set to angles corresponding to those of the plates or otherwise set.
The water or liquid to be filtered is either forced or allowed to flow up between
the plates from a chamber at the bottom part of the vessel the solid impurities
precipitating or depositing themselves upon the surface of the plates during said
up-flow or up-travel. The solid deposit slides down the plates and accumulates
in the bottom chamber from which it can be removed when the flow is shut off.
Dated this 20th day of January 1886.

Used for Separating Solid Impurities from Water or other
Liquids.
I, ANDREW HOWATSON of 7 Lavender Hill, Surrey, 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 certain novel detail methods of arranging plates, or
appliances in vessels of any suitable shape but preferably in vessels that shall
correspond in shape, or approximately so to suit the position, or arrangement of the
plates, for the purpose of separating solid or flocculent impurities from water, or
other liquids, which is; or are, passed upwards through the apparatus, said up-flow
or passage being uniform or otherwise according to the nature of the liquid under
operation.
The invention is based upon a previous Patent applied for by me on the
23rd May 1885 No 6351 in the specification of which Letters Patent reference is
made to the employment of corragated, fluted, or zigzag plates arranged vertically
within a vessel and having between said plates a series of corresponding passages
all tending upwards but deviating alternately from side to side, said passages being
for the up-flow of liquid from the lower part of the vessel, this forming a receptacle
in which the solid matter deposits itself after sliding down from said plates, the
clear water flowing away from the upper part of said vessel in any convenient
manner.
Now according to my present invention, employ flat plates set out of the
perpendicular or at an angle, or angled plates can be set vertically, the angles being
of the same or of different lengths or corrugated plates may be set at an angle
with their corrugations running vertically, or otherwise, or other equivalent forms
of plates can be arranged within a vessel which may be upright or arranged with
sides set to angles corresponding to those of the plates or otherwise set.
The water or liquid to be filtered is either forced or allowed to flow up between
the plates from a chamber at the bottom part of the vessel; the solid impurities
precipitating or depositing themselves upon the surface of the plates during said
up-flow or up-travel. The solid deposit slides down the plates and accumulates in
the bottom chamber from which it can be removed when the flow is shut off.
The annexed sheet of drawings show several examples of arrangement of plates
according to my present invention. In Figures 1 and 2 I show flat plates B, B,
arranged above one another on suitable supports and at fixed distances apart by
notched bars or otherwise. The supports are preferably metal rods simply laid in
the tank A for the plates, to rest upon but without interfering with the upward
flow of water which passes up, the chamber L through between them.
Figure 3 shows a series of bent plates B forming two angles in themselves these
are arranged vertically in the tank A as are also the plates shown at Figure 4, in
which the angles are formed by kinking the plates top and bottom.
Figure 5 shows a series of similar plates the ends kinked at greater angles.

page_text: Figure 6 represents a tank with a series of corrugated plates, the corrugations
being set vertically and at an angle corresponding to that of the tank itself.
Figure 7 represents a series of plates with the lower ends vertical, the remainder
of the plates being set at an angle in a tank also set at an angle.
Figure 8 indicates a series of plates with the upper ends less kinked than the
lower ends, arranged in a vertical tank, and Figure 9 shows a series of perfectly
flat plates set at an angle in a tank correspondingly set.
In Figure 2, in the drawings annexed to my previous specification before
referred to, the chamber L is in connection with the lower part of the chamber D
by a pipe M. It has been found that this pipe when treating certain liquids
becomes choked as to interfere with the proper flow of liquid from the mixing
chamber into the precipitating chamber. I now dispense with the pipe M and
connect two angle plates P, P, to the bottom of the partition Q dividing the two
tanks whereby an unchecked flow is ensured.
It will be observed by the annexed drawings that the method of separating
solid impurities from water or other liquids is the same or substantially the same
as that described in my previous Patent, the present invention consisting of a
novel application of shaped plates, or of tanks shaped to suit plates in which the
plates are made with angles, or set to form angles and having passages also at
angles along which a constant flow of liquid in an upward direction is established
and within which the impurities are separated from the liquid by gravitation and
slide down into the chamber L to be drawn off by the sludge cock N in the manner
described in my before mentioned previous specification.
In the several examples shown on the drawings the respective plates are set at
the same distance apart from each other but said distances may be otherwise
arranged as desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is:-
The several improved arrangements of plates set within tanks as hereinbefore
described, whether said plates be set at an angle or formed with angles and set in
vertical tanks or as angled plates, or plain flat plates, or corrugated plates set in
angled tanks, or in vertical tanks in which impurities, solid or flocculent matter,
may be separated and precipitated from liquid while such liquid has a constant
upflow through between said plates as set forth.
