Improvements in the Construction of Tanks and Filters for Precipi-
tation and Filtration Purposes, and in the Appliances and Fittings
arranged for use in the same.
I, HENRY LEONARD HINNELL of 41 Corporation Street, Manchester in the County of
Lancaster, Civil Engineer, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improvements in the construction of tanks and
filters for the precipitation and filtration of solids and liquids from, sewage, bleachers,
dyers, tanners, fell-mongers and manufacturers refuse and in the appliances and
fittings employed and arranged therein. The tanks are arranged with distributing
troughs and weir walls to which are attached weir-plates. The distributing troughs
are placed near the top of the tanks where the liquids and solids enter and are
arranged so that an uniform distribution of the same takes place the full width of
the tanks immediately the liquids and solids flow into the tanks. The weir walls
fitted with plates are arranged at uniform distances in the tanks and they tend to
cause a rapid precipitation of the matters in suspension in the liquids; the flocculent
matters in the same being arrested by the weir plates which form traps when partly
submerged and partly above the normal flow of the liquids and supported by brackets
from the weir walls. The straining filter straps are composed of troughs having a
division plate in the same, the lower portion of which is perforated. One side of the
traps is filled with fine or coarse materials and the other side or portion is an open
channel; the liquids flowing pass through the filtering materials and which strains
out any matters in suspension in the liquids and flowing through the perforated plate
rises into the other portion of the trough. The straining filter traps are arranged as
a moveable appliance so that the materials forming the filter can be removed
expeditiously.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation of my improvements in the construction of tanks and
filters for the precipitation, purification, and filtration of solids and liquids from
sewage, bleachers, dyers, tanners, fell-mongers and manufacturers refuse, and Fig. 2.
is a plan of same showing one or more tanks.
A, A1 and A2 are the divisions of a tank; B the side walls; B1 weir walls; C conduit
leading to the tanks; D sluice valve or "penstock"; E distributing troughs; G weir
plates; I conduit from tanks; K outlet channel; L straining filter trap, and
M receptacle for solid or other matters.
The tanks A, A1 and A2 are constructed by means of the sides B and weir walls B¹,
and are arranged or provided with the distributing troughs E and the weir plates G as
shown in the drawings. The distributing troughs E are placed or fixed near the
top of the wall or side B of the tank 'A where the liquids and solids enter. The
liquids and solids are conveyed from any convenient or desired source to the conduit C,
from whence they are admitted by the sluice valve or "penstock" D to the
distributing troughs E; the latter being provided with the openings O placed at equal
or other distances from each other and of equal or other sizes to ensure of an uniform"
distribution of the same being effected the full width of the tank or tanks A
immediately the liquids and solids flow therein. Opposite the sluice valve or
"penstock" D the distributing troughs E may be provided with the angular or
concaved projection N to direct the liquids and solids under treatment in both
directions. The weir walls B¹ are fitted with the weir plates G, and are arranged as
shown in the drawings or in any other equivalent manner at uniform or other
distances to effect a rapid precipitation of the matters in suspension in the liquids;
the flocculent matters in the same being arrested by the weir plates G, the latter
forming traps when their lower ends are 'submerged and their upper ends are above
the normal flow of the liquids. The distributing troughs E are supported from the
weir wall.B by the brackets S as shown in Fig. 1 or they may be built in the wall B
and the weir plates G are supported by the arms P secured in the upper end or side
of the weir walls B, The tanks A, A1 and A2 are connected with each other by the
openings T provided with doors or other closing arrangements which may be of
any desired size and of any required number to effect equal distribution of the
liquids admitted therein. The bottom of the tanks A, A and A2 are inclined as
"

page_text: shown in the drawings to allow of the same being emptied and cleaned out
thoroughly in a ready and efficient manner, the same inclining to the outlet W
by which the entire contents may be drained and carried away to any point at a
lower level. If desired the outlets W may be provided with sluice valves to
allow of one tank being shut off from another when placed side by side as shown
in the drawings or otherwise, The liquid under treatment flows from the division
of the tank A into the conduit I froin whence it passes into the channel K and
through the straining filter trap L, the latter consisting of bars disposed side by
side longitudinally, or by other equivalents, such as, a plate or plates provided
with holes or openings. The straining filter trap bars or plate or plates L are
inclined as shown in the drawings, the upper end resting on the inner edge or
ledge of the receptacle M; the latter being used for receiving the refuse or flocculent
matter collected on the bars or plate or plates L of the filter trap when removed
therefrom by means of a rake, or by any other cleansing apparatus that may be
employed. To ensure of the efficiency of the straining filter trap the bars or plate or
plates L may be covered with filtering cloth or other suitable material or materials,
substance or substances. The straining filter trap being composed of bars or a
perforated plate or plates may be removed and renewed or replaced expeditiously.
Having thus stated the nature of my invention and described the mode of performing
the same, I would have it understood that I do not confine nyself to the precise
details or configuration of the parts I have shown and described as the same may be
varied or modified without departing from the principle of my invention and that the
same may be applied either jointly or severally as shown, but what I claim and desire
to be secured to me by Letters patent is :-
The general arrangement-either separate or combined-of parts composing the
improvements in the construction of tanks and filters for precipitation, purification
and filtration of solids and liquids from sewage, bleachers, dyers, tanners, fell-mongers,
manufacturers refuse and the like as herein before described and as illustrated in the
annexed drawings.
