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 :-
A New System of Sewage Disposal.
This is a scheme to prevent the pollutions in Drains and Water-courses arrising
from the offensive sewage of Dwellings and Public Works, by means of a Portable
Cesspool box and Filter.
These act as a closed receptacle and filter intercepting between the sewage conduit
pipes and attached to them at the inlet and outlet by joints held in place by some
simple contrivance all in such a way as to admit of a rapid removal by the men who
lift it away and who as readily attach another in its place.
Small and large sized boxes lifting by hand and by mechanical power being used
for the different volumes of sewage, these boxes being made suitable for removal 'to
the most distant manure depot. In many cases, boxes of any figure having the
requisite strength of materials might do, provided they have the inlet rightly placed
to receive the pollutions, and an outlet from the filtering materials towards the pure
water channels, closed by lids, and fitted with ordinary stop-valves to prevent smells
and leakage while in place, or during the time of removal, but generally exactness in
construction will be necessary. The example in the drawings will only serve to show
what is substantially the distinctive features of this New System of Sewage Disposal.
The kinds, conditions and situation in sewage pollutions being so multifarious will
require a corresponding variation in relative details.
one example of its application to the water-closet sewage in towns, a small pit
below the street pavement, or a place in the ground or wall accessible to the nightsoil
men has to be chosen, for the purpose of holding the apparatus.
The specimen in the drawings being for the service of six small houses or an average
of twenty-four persons, the main filter being changed at longer intervals but the
cesspool daily or weekly according to the system of attendance set up.
The boxes in the drawings are made of sheet-iron by riveting and soldering, but
generally some of the parts will be made by casting and finishing in the usual way of
the trade. In the figures the sheet-iron or thin edges are represented by a single line,
and a space shown at the loose couplings for India rubber or a packing ring. The
India rubber or close coupling at the street pipe outlet is only preventive of air from
covered up sewers. The cesspool inlet which partakes of the shape and nature of the
plug stop-cock, has the through opening or flow passage, entering in at the end and
out at the side, (d Fig. 2) and not in the usual way. The plug or valve (f) which
turns inside being hollow and open at the end, serves as a shell or casing (f) to
receive the end of the pollutions pipe (G H) within it, which then serves for the

page_text: upling joint required at this inlet. This end of the pollutions pipe (H) is also formed
to a stop valve by having for the valve a thin casing (G) outside the pipe, to turn
opening and shutting. The movable hose allows the end of this pipe with its stop
lve to be entered into the opening of the other stopcock, which then requires to be
rust home, to bring the collar (1) by which each valve is turned, into position for
e spanner or pin key to take its seat, to operate both valves at the same time. The
If turn required to operate the valve is travelled in the screw in the stuffing
x (UV) which along with the slight taper of the valve tightens it in shutting and
ckens it in opening. A gland nut or another packing ring not shown in
awings, will be added when required.

into a stop valve by having for the valve a thin casing (G) outside the pipe, to turn

valve to be entered into the opening of the other stopcock, which then requires to be
thrust home, to bring the collar (1) by which each valve is turned, into position for
the spanner or pin key to take its seat, to operate both valves at the same time.
half turn required to oporate the valve is travelled in the screw in the stuffing
box (UV) which along with the slight taper of the valve tightens it in shutting and
slackens it in opening. A gland nut or another packing ring not shown in
drawings, will be added when required.

The
Charcoal will do for a filtering material and in the case of houses with gardens,
partly filling the cesspool with earth dressings would make it more manageable for
servants atendance and the private dungstead. But the kinds of filtering materials
or the chemicals placed in the boxes or the placing of the outlet in the cesspool
higher up for subsidence, or using the cesspool as a convenience for any process
previous to filtration and any other contingent or incidental aids, are here left to the
convenience of each district, and the option of the persons in charge.
This portable scheme is expected to be of service in the large area or district
system of treatment is. the purifying at a few points only of the numerous drains,
in order to prevent the pollutions entering the larger water-courses.
But a more full and better application of this system lies in keeping the pollutions
out of the drains as well, by using the apparatus for very small areas or better still
by taking each building, publick works, or other small source of pollution for separate
treatment. The space then exposed to pollution is minimised through confining it to
a short length of conduit pipe at the source and the offensive sewage is kept out of
the street or common sewers. In this way the injurious effects arrising from the
junction of dwellings with common sewers can be negatived, and a town with its
small streams freed from sewage effects, and not by the mere riddance of sewage at
the outfall.
This scheme is applicable to an isolated house or to any locality requires no expen-
sive drainage works as surface streams will suffice for the purified effluent. It is
capable of doing all that other schemes can do, and through overcoming the difficulty
of the water-closet system, by making it unobjectionable and safe inside the house is
vastly superior to all other schemes.

page_text: By these separate collections what is fitted for manure can be sent to fertilize the
land, otherwise a system of collection is in readiness for its final disposal by car-
bonizing or in any other way.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claini is
(1) As an essential feature of the apparatus, the use of a cesspool or collection box
or set of boxes, conjoined with a filter, draining off and purifying the effluent
water.
(2) The main novelty lies in the portable form of nature or the apparatus, adapting
it for all the noisome operations being performed after removal to the manure depot
or other place for emptying, and the permitting the whole of the apparatus being kept
in a freshened state by cleansing and disinfecting before returned.
