Improvements in Apparatus Employed in the Clarification of
.
Sewage.
I ARTHUR FAWCETT, Old Town Hall, Wakefield in the County of York Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for purpose aforesaid wherein is employed a
waterwheel, employed for imparting the requisite motion to appliances for delivering
and mixing a quantity of lime (or other medium) and water to be added to the sewage
for purpose of clarifying the latter. A difficulty in applying such apparatus often
arised by reason of the levels at which the sewage outlet, and the clarifying tanks, are
of necessity situate that the requisite flow or head of sewage to turn the water wheel
cannot be obtained, and the object of this invention is to remedy that defect.
According to this my said invention I employ at the mouth of the sewer, a tank, tho
outlet of which, is closed by. a sluce-the upper part of which is by chain passing over
guide pulleys, or by lever connected with a bucket or vessel having a valve in the
bottom or lower part thereof. Near the upper level of the tank, is an orifice and pipe
or shoot, through which when the tank is filled, sewage flows into the bucket or vessel
referred to, until the weight of sewage therein counterbalances the weight of the sluce,
the bucket descends, and by the connecting chain or lever lifts the sluce, and permits
the flow of sewage from the tank so driving the wheel and the clarifying medium,
delivering and mixing machine. Meanwhile the descent of the bucket to the floor
level, or to a stop piece will have opened the valve, or operated a lever connected
therewith, and the sewage therein is discharged, whereon the sluce being the heavier
at once descends, lifting the bucket and closing the orifice, until a further accumulation
of sewage in the tank operates the bucket and sluce and will as above descend, the
whole being automatic in its operation.

Improvements in Apparatus Employed in the Clarification of
Sewage.
1, ARTHUR FAWCETT, Old Town Hall, Wakefield in the County of York, 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 apparatus for purpose aforesaid wherein is employed a
waterwheel, employed for imparting the requisite motion to appliances for delivering and
mixing a quantity of lime (or other medium) and water to be added to the sewage
for purpose of clarifying the latter. A difficulty in applying such apparatus often
arised by reason of the levels at which the sewage outlet, and the clarifying tanks, are
of necessity situate that the requisite flow or head of sewage to turn the water wheel
cannot be obtained, and the object of this invention is to remedy that defect:
According to this my said invention I employ at the mouth of the sewer a tank the
outlet of which is closed by a sluice the upper part of which is by chain passing over
guide pulleys, or by lever connected with a bucket or vessel having a valve in the
bottom or lower part thereof. Near the upper level of the tank is an orifice and pipe
or shoot, through which when the tank is filled, sewage flows into the bucket or vessel
referred to, until the weight of sewage therein counterbalances the weight of the
sluice, the bucket descends and by the connecting chain or lever lifts the sluice and
permits the flow of sewage from the tank so driving the wheel and the clarifying
medium, delivering and mixing machine.
Such being the nature and object of this my said invention, the following is a complete
description of same reference being had to the accompanying drawings:-
Fig. 1 is a general view in elevation of my improved apparatus for the clarification
of sewage.
Fig. 2 is a side elevation of the sluice, bucket, and connections.
Fig. 3 is a plan view of Fig. 2.
According to this my said invention, I employ at the mouth of the sewer, a tank 1
the outlet 2 of which is closed by a sluice 3 the upper part of which is by chain 4
passing, over guide pulleys 5-5 or by lever connected with a bucket or vessel 6 having
a valve in the bottom or lower part thereof. Near the upper level of the tank 1 is an
orifice and pipe or shoot 8 through which when the tank 1 is filled from the sewers,
sewage flows into the bucket or vessel 6 referred to, until the weight of sewage therein
counterbalances the weight of the sluice 3 whereon the bucket descends, and by
the connecting chain 4 or lever lifts the sluice 3 and permits the flow of sewage from
the tank 1 so driving the wheel 9 and the clarifying medium, delivering and mixing
machine. Meanwhile the descent of the bucket to the floor level, or to a stop piece will
have opened the valve 7 or operated a lever connected therewith, and the sewage in 6
is discharged, whereon the sluice 3 being the heavier at once descends, lifting the

page_text: bucket 6 and closing the outlet of the tank 1, until a further accumulation of sewage
in the tank 1 operates the bucket 6 and sluice 3 and will as above descend, the whole
being automatic in its operation.
Having now particularly described and ascertained the nature of this my
Invention and in what manner the same is to be performed I declare that what I
claim is :-
The sluice 3 connected and combined with the vessels 1 and 6, latter having dis-
charge valve such as 7, the sluice and vessel operating as and for purpose herein fully
described.
