COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for the Treatment of
Sewage and like Liquids.
I, EDWARD WILLIAM IVES, of Littleover, in the County of Derby, Civil.
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 improvements in apparatus which may be used
in connection with the arrangement shown and described in the Specification of
Letters Patent granted to me numbered 16,034 and dated the 20th day of June
1896; and has for its object an arrangement by which, 1st, the filter is effectually
acrated after each charge of effluent, and 2nd, by certain mechanical arrange-
ments, the automatic discharge of the tank is effected in a given time, and the
number of times of such discharge can be recorded by well known means.
In order that my invention may be fully understood, I will describe the same
in detail by making reference to the accompanying drawings, in which Fig. 1
represents a plan view of a sewage tank and filter, part of the filter cover is
removed and shows the bracings beneath.
Fig. 2 is a sectional elevation through irregular line a, b.
Fig. 3 is an enlarged sectional detail through line C, d.
Fig. 4 is an enlarged sectional detail through irregular line e, f.
Fig. 5 is an enlarged sectional detail showing the valve R fitted at the bottom
of bucket C and
Fig. 6 is an enlarged sectional detail through outlet chamber pipe and carrier,
on one end of line a, b.
In any suitable position near to tank N, Figs. 1 and 2, I construct chambers A
and B shown in sectional detail by Fig. 3, and in chamber A I place a movable
receptacle or bucket C supported by a chain or the like D passing over pullies E
and H, secured on shafts F, F, working in bearings G, G, of ordinary construction
secured in any convenient manner.
The chain or the like D is attached to a valve J, in chamber B, the valve being
provided with a seating K formed on pipe U communicating with the carrier M
through which part of contents of the tank N is discharged in the direction of
the arrows shown by Figs. 2 and 6.
The effluent is delivered into the tank N from trough W and when valve J is
closed the effluent rises in said tank, into the filter T, above tank, displacing the
air therein and thus aerating the effluent.
When the valve J is open, the overflow arm 0¹, (see Figs. 2 and 6) forms the
overflow from tank N, into chamber B, and away.
A communication, by means of pipe P, is made between the filter T and
chamber A, the end of said pipe within the chamber is provided with a tap Q, for
the purpose of regulating the flow of liquids from the filter T into the bucket C
in chamber A. The tap Q is so regulated that by the time the effluent has
risen to the top of the filter T, and has been running through filter T a certain
077

page_text: time, sufficient liquid will have been discharged through the tap Q into
bucket C as is sufficient to overcome the weight of valve J, thus raising the
valve J clear of tts seating K, thereby allowing the effluent to escape through
overflow 0¹, valve J and pipe U, into the carrier M, thus discharging the over-
flow from the tank N through valve J; and away.
The bottom of the bucket C is provided with a valve R shown in detail by
Fig. 5, and is constructed with a rubber or other suitable water tight face.
Upon the bucket C being sufficiently full of effluent of the like as to cause
its descent, on arriving at the bottom of chamber. A, the valve R will be forced
from its seat R2, thus allowing the contents of bucket C to escape through pipe S
provided with a tap V as shown in Fig. 4.

By the regulation of tap V any required time may be allowed for the empty-
ing of bucket C, and upon the bucket C becoming empty, the weight of the
valve J will overcome the resistance of the empty bucket C and close automati-
cally, thus bringing the bucket C back to its original position ready for the
refilling of the filter T, and by connecting the bucket C, by means of a chain or
the like, with either an engine counter or what is known as a watchman's "tell
tale" the number of times the bucket has been filled and emptied can be auto-
matically recorded; on each descent of the bucket the lever of the recording
instrument is operated and the descent enumerated on the dial of the instrument.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The movable bucket C, counter-balanced by the valve J, the bucket actuating
the valve R in such a manner as to discharge the contents of the filter T, or the
effluent from tank N, into one or more channels, the time taken for such discharge
being regulated by the, taps or valves Q and V, substantially in the manner
herein set forth and illustrated by the opening drawings.
