ALEXANDER MELVILLE CLARK of 53, Chancery Lane, in the County of
Middlesex, Patent Agent. "IMPROVEMENTS IN APPARATUS FOR RECEIVING,
DISINFECTING AND SEPARATING FOCAL AND OTHER MATTERS" [A communication
from abroad by Philibert Schlosser, of Paris, France]
This Invention relates to the tub system of cesspool for receiving and removing
focal matters from houses, and it has for its object to effect mechanically and
automatically the separation of the solid from the liquid parts of focal or sewage
matters in houses, and the disinfection of the liquid portion by a composition
whereby it is rendered innoxious so that it may be run away into drains or evon
in open street gutters without causing any nuisance.
The Invention consists in a filter vessel or tub in which the excrementitious
matters are received, whereby the dilution and carrying off of the solid or viscous
portions by the urine and other waters (as is the case with other apparatus of this
kind whether the final outlet be at the upper or lower part of the apparatus) is
provented, and whereby the overflowing of the apparatus owing to the obstruction
of the filters by paper and other solid matters, as well as by the slime of the
excrementitious matters themselves is avoided, as well as the excessive retention of
the liquid portions, and the two frequent removal of the tubs.
According to this Invention the filtration takes place in an upward direction and
through an oblique surface, so that the solid or viscous matters are not forced
against the filtering surface and the liquid is free to run off alone.

page_text: The Invention is illustrated by way of example in the accompanying Drawings,
wherein Figure 1 is a perspective view, Figure 2 a vertical section, and Figure 3
a top view of the portable filter tub or vessel. Figure 4 is a top view of
the same with its cover applied for removal, the cover being fixed by bolts and

its upper part with a movable annular filter or percolater e f g h i j k l m n. 1
This filter is constructed with straight double outer walls and an inner wall in
form of a truncated cone, the latter as well as the inner of the straight walls being
perforated with a number of small holes, and the conical space ghil m n filled
with a disinfecting absorbent composition. The filter is provided with an outlet o
leading from the gutter between the double outer walls. The tub or vessel is
also furnished interiorly with a perforated tube ttt also filled with the disin-
fecting absorbent composition. The excrementitious matters generally fall centrally
into the tub or vessel, and settle uniformly therein. The liquid forming the larger
portion of the sewage (without including washing and other household water)
quickly rises to the lower part of the annular filter in traverses the perforated
walls, ihm n, the disinfecting composition contained in the space g h i l m n
and the walls giln into the gutter e fijk n whence it runs off through the
discharge pipe o. tt is a foraminous tube extending the whole height of the
tub and terininating beneath the filter, also filled with disinfecting composition to

is provided with a stopper t' in order (should the liquid in the tub remain stagnant
at this level for a length of time) to prevent the excessive dilution of the disin-
fecting composition and maintain an unused reserve between t and t¹.
In order to provide against the discharge of an unusually large volume of water:
into the tub or vessel the conical cap or chute illustrated in Figure 5 is employed.
This cap is connected to the lower end of the soil or drain pipe X and rests on the
top of the tub or vessel, and it is made of the form shown, and has an internal
corrugated or fluted cone, forming gutters or channels whereby (aided by the
contraction of the internal thoroughfare at ww¹) the water is conducted for the
most part directly into the gutter efijkn of the filter where it mixes with
and is disinfected by the water that filters upwards through the disinfecting
medium. The corrugations or flutes of the internal cone of the cap are deepest at
the middle and they almost meet the surface of the outer cone at the extremities.
They may be formed in one with or attached to the cap.
The construction and form of this apparatus may be. varied without departing
from the Invention for example, the filter might be a hollow perforated cylinder
placed axially in the receiver.

ALEXANDER MELVILLE CLARK of 53 Chancery Lane in the County of
Middlesex Patent Agent "IMPROVEMENTS IN APPARATUS FOR RECEIVING
DISINFECTING AND SEPARATING FOECAL AND OTHER MATTERS." A communication
from abroad by Philibert Schlosser of Paris, France.
This Invention relates to the tub system of cesspool for the reception and
removal of focal matters, and it has for its object to effect mechanically and
automatically the separation of the solid from the liquid parts of foecal or sewage
matters in houses and the disinfection of the liquid portion by a composition,
whereby it is rendered innoxious so that it may be run away into drains or even
in open street gutters without causing any nuisance.
The Invention consists in a filter vessel or tub to receive the excrementitious
matters so constructed as to prevent the dilution and carrying off of the solid or
viscous portions by the urine and other waters (as in other similar apparatus
whether the final outlet be at the upper or lower part) as well as to avoid overflows
in consequence of the obstruction of the filters by paper &c. and by the slime of
the excrementitious matters and the necessity for the frequent removal of the tubs
in consequence of an excessive proportion of liquid being retained in them.
According to this Invention the filtration takes place in an upward direction and
through an oblique surface so that the solid or viscous matters are not forced
against the filtering surface and the liquid is free to run off alone.
The Invention is illustrated by way of example in the accompanying Drawings
wherein Figure 1 is perspective view, Figure 2 a vertical section, and Figure 3
a top view of the portable filter tub or vessel. Figure 4 is a top view of
the tub with its cover 8 q made in two parts which is placed on it before
removal, the cover being fixed by bolts and lugs u, u Figure 5 shows a section,
and Figure 6 a perspective view of a conical chute or cap to be applied to the tub
or vessel for conducting off exceptionally large quantities of water without passing
through the filter. Figure 7 shows a modification of the chute or cap drawn to a
larger scale. The same letters of reference indicate the same parts in all the
Figures.
A B C D is a tub or vessel provided with side handles p p' and furnished at
its upper part with a movable annular filter ef g h i j k l m n. This filter is
constructed with a vertical outer wall gi ln and an inclined inner wall i h m n
in form of a truncated cone both perforated with small holes, and the conical
space g h i l m n between them is filled with a disinfecting absorbent com-
position. The filter is surrounded by a gutter provided with an outlet o. The tub
or vessel is furnished interiorly with a perforated tube t t t also filled with the
disinfecting absorbent composition. The excrementitious matters generally fall
centrally into the tub or vessel and settle uniformly therein. The liquid which
forms the larger portion (without counting washing and other household water)
quickly rises to the lower part of the annular filter, traverses the perforated walls
and the disinfecting composition contained in the space between them, and is
received in the gutter surrounding the filter, whence it runs off through the
discharge pipe o. ttt is a foraminous tube extending the whole height of the
tub and terminating beneath the filter, also filled with the disinfecting composition
to act on the matters in the tub as it becomes filled in order to render them
imputrescible and innoxious. This tube t is fixed in the receiver by the lug v and
is provided with a stopper t¹ in order (should the liquid in the tub remain stagnant

page_text: at this level for a length of time) to prevent the excessive dilution of the disinfecting
composition and maintain an unused reserve between tand t'. In order to provide
against the discharge of an unusually large volume of water into the tub or vessel,
the conical cap or chute illustrated in Figures 5 and 6 is employed. This cap W
is connected to the lower end of the soil pipe or drain pipe X and rests on the top
of the tub or vessel by its flange Y Z. It is made of the form shown and has an
internal corrugated or fluted cone forming gutters or channels whereby (aided by
the contraction of the internal thoroughfare at W₁ W') the water is conducted for
the most part directly into the gutter surrounding the filter where it mixes with
and is disinfected by the water that has filtered through the disinfecting medium.
The corrugations or flutes of the internal cone of the cap W are deepest at the
middle and they almost meet the surface of the outer cone at the extremities.
They may be formed in one with or attached to the cap.
The construction and form of this apparatus may be varied without departing
from the Invention for example, the filter might be a hollow perforated cylinder
placed axially in the receiver.
•
In Figure 7 the saine letters of reference are used to denote the same parts as in
Figures 1 to 6. In this modification a distributor 1 is interposed between the
cap. W W and the discharge or soil pipe X, to receive the water from the latter
and conduct it into an annular cup 2 wherein the water is distributed uniformly
around the entire circumference so that as it overflows from the cup it necessarily
runs down the sides of the cap W until it reaches the gutter around the filter.
The distributor 1 is fixed in any suitable manner below the soil pipe X and is
furnished with hooked arms 3 to which the cap W W¹ may be attached when the
latter is lifted off before removing the tub. The distributor 1 may receive other
discharge or soil pipes as indicated by X' X. The water runs down the cap into
the gutter and runs off therefrom as before described, and as shown by the
arrows.
The above arrangement is chiefly applicable in cases where large quantities of
liquid are discharged at once into the pipe X.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein before in part recited Letters Patent is :—–—
1st. A filter tub or vessel in which the separation of the solid and liquid parts
of foecal matters is effected by upward filtration through an oblique surface and a
disinfecting composition substantially as herein shown and described for the
purpose specified.
2nd. In a filter tub or vessel for separating the solid and liquid parts of foecal
matters, the combination of a tub or vessel A B C D, annular filter with inclined
walls e f g h i j k l m n discharge orifice o, removable perforated tube t t¹ t²,
and conical cap W, the whole substantially as before described for the purpose
specified.
3rd. In a filter tub or vessel for separating the solid and liquid parts of foecal
matters, the combination of cap W W with distributor 1, 2 and discharge pipe X
arranged substantially as described and for the purpose specified.
In witness whereof I the said Alexander Melville Clark have hereunto set
my hand and seal this First day of June A.D. 1882.
