Improvements in and relating to Apparatus for Delivering Night-soil,
Rain Water, and the like to Drains or Sewers.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
15 Southampton Buildings, in the County of Middlesex do hereby declare the
nature of the invention to be as follows:-
This invention relates to apparatus for automatically delivering night-soil, rain-
water, slops and the like, which fall from the several floors of a house into the said
apparatus, to drains or sewers by the direct action of water.
In a pit in or near the house is fixed by brackets against the wall a closed vessel
into which descends the waste pipe directly from the water closet and if desired also
the rain pipes and pipes for delivering slops or the like.
This vessel is provided with a siphon having two branches the shortest of which
terminates at the bottom of the vessel while the longest serves for delivering the
matter, which is conducted through the general pipe of the house and thence into
the drains or sewers.
On one side of the said vessel, which has an inclined bottom in order that the
whole of its contents may be discharged into the siphon, is provided a small
reservoir having a float and communicating with the vessel through a small siphon.
Water passes constantly into this reservoir through a cock with two plugs.
One of these plugs is operated by hand for obtaining a constant supply, while the
second plug is controlled by the aforesaid float.
It will now be easy to understand the operation of my apparatus, which is as
follows:
The solid and liquid matter falls directly from the water-closets through the
waste pipe into the said vessel.
This vessel is supplied by the general water pipe with water which flows
regularly through the first of the said plugs into the reservoir in order to pass thence
through the small siphon into the vessel wherein it mixes with the waste matter
coming from the waste pipe.
The level of the liquid is thus gradually raised in the vessel and at the same time
in the large siphon, thereby causing also a gradual compression of the volume of air
contained in the said siphon.
When the level of the liquid in the vessel reaches a certain point the level of the
liquid which the large siphon contains, and the upward movement of which is
retarded by the compression of the air, arrives at a point at which the compressed
air, being considerably reduced in volume and having therefore acquired a pro-
portionately high pressure, dispels the liquid which is contained in a bent portion of
the siphon pipe and passes with this liquid into the general drain pipe.
The pressure having ceased above the level of the liquid in the large siphon the
liquid in the latter rises quickly to gain the level of the liquid in the vessel, and
sets the large siphon in action so as to completely empty the reservoir and at the
same time the vessel the contents of which flow into the general pipe leading to
the drains, leaving in the large siphon a sufficient quantity of liquid to aid in the
following delivery.
It will be observed that when the level of the liquid rises in the vessel it rises

page_text: at the same time in the reservoir thereby causing at a given moment the opening of
the second cock by the upward movement of the flat. The water arrives in
abundance through the second cock, the level rises rapidly in the vessel, the large
siphon acts and the whole is emptied into the general pipes while the second cock
is closed. Water continues to flow from the first cock without interruption in such 5
a manner that as the reservoir and then the vessel is filled with night-soil the large
siphon acts as hereinbefore explained and a fresh delivery takes place.

Improvements in and relating to Apparatus for Delivering Night-soil,
Rain Water, and the like to Drains or Sewers.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 automatically delivering night-soil, rain
water and slops which fall from the several floors of a house into the said apparatus,
to drains or sewers by the direct action of water.
In order that the nature of my invention may be easily understood I have
represented it in the accompanying drawing in which
Figure 1 is a vertical longitudinal section of my apparatus arranged in the drains
of the house.
Figure 2 represents a side view partly in vertical section on the line x-y of
Figure 1.
Figure 3 is a plan of the apparatus with the upper part removed.
Figure 4 is a modification illustrating the automatic starting of siphon.
In a pit in or near the house and fixed against the wall thereof by means of
brackets, is a closed vessel B into which descends the waste or soil pipe C directly
from the water closets, and if desired also the rain pipes and pipes for delivering
slops or the like.
This vessel B is provided with a siphon S having two branches the shortest of
which terminates at the bottom of the vessel while the longest serves for delivering
the matter which is conducted through the general pipe of the house and thence
into the drains or sewers.
On one side of the vessel B, which has an inclined bottom as shown in Figure 1
in order that the whole of its contents may be discharged into the siphon S, is
provided a small reservoir M having a valve or cock and float and communicating
with the vessel B through a small siphon m. Water passes constantly into this
reservoir through the valve or cock which has two plugs, and r¹.
One of these plugs r, is operated by hand for obtaining a constant supply, while
the second plug, r', is controlled by the aforesaid float.
The operation of my apparatus, will now be readily understood, which is as
follows:
The solid and liquid matter falls directly from the water-closets through the
waste pipe C into the vessel B.
This vessel is supplied by the general water pipe with water which flows regularly
through the plug r into the reservoir M in order to pass thence through the small
siphon m into the vessel B wherein it mixes with the waste matter coming from the
waste pipe C.
The level of the liquid is thus gradually raised in the vessel and at the same

page_text: time in the large siphon S, thereby causing also a gradual compression of the volume
of air contained in the said siphon.
When the liquid in the vessel B reaches a level indicated by X, the level of the
liquid in the large siphon S, the rise of which is retarded by the compression of the
air, will have risen to the point Z. At this moment the compressed air, being
considerably reduced in volume and having therefore acquired a proportionately
higher pressure, forces down the liquid which is contained in a bent portion S' of
the siphon pipe and passes with this liquid into the general drain pipe.
The pressure having ceased above Z in the large siphon S, the liquid in the latter
rises quickly to the level X in the vessel, and sets the large siphon in action, so as
to completely empty the reservoir M, and at the same time the vessel B, the
contents of which flow into the general pipe leading to the drains, leaving in the
large siphon S a sufficient quantity of liquid to aid in the following delivery.
It will be observed that when the level of the liquid rises in the vessel B it rises
at the same time in the reservoir M, thereby causing at a given moment the opening
of the cock by the upward movement of the float. The water flowing quickly
through the cock r¹, the level rises rapidly in the vessel B, the large siphon S acts
and the whole is emptied into the general pipes while the cock is closed.
Water
continues to flow from the cock without interruption as above explained and in
such a manner that filling the reservoir M and then the vessel B concurrently with
night soil the large siphon S acts as hereinbefore explained and a fresh delivery
takes place.
As a modification of the system I may also arrange my apparatus as represented
in Figure 4. The siphon S is arranged as before and branches off at the lower part
of the vessel B receiving the night soil from the waste pipe C of the house. This
vessel B moreover carries a vessel A which communicates with it at band which is
divided into two compartments 1 and 2 by means of a vertical partition K pierced
with communicating holes.
Into these two compartments project the tubular branches d d' which form the
prolongation of the pipe D fixed at the top of the siphon S. As shown in the
drawing the brauch d is somewhat longer than the branch d¹.
The compartment 1 contains, besides the branch d, a small siphon J the top of
which is lower than that of the delivery siphon S.
When the level rises in the vessel B, in consequence of the fall of matter arriving
through the pipe C, the gases are compressed in the system S, thus stopping at o, p
in the said siphon the upward movement of the liquid which continues to rise in the
vessel B and in the vessel A until it passes over the top of the siphon J. This
latter begins to act immediately and empties the vessel A, passing its liquid either
into the lower part of the siphon S or directly into the drain or sewer.
The compartment 1 which contains the siphon J being emptied first the lower
part of the tube d is uncovered and allows the escape of the compressed air through
the tube D of the siphon S. The latter commences to act at once, by reason of the
sudden rise of the level o p, and the vessel B is completely emptied.
During this time the liquid which has remained in the compartment 2 of the
vessel A flows into the compartment 1 through the holes pierced in the partition K
and obturates the lower part of the tube d, while that of the tube d' is freed. The
air then rises through the latter tube in order to supply the siphon S which will be
emptied, and it is the compression of this new mass of air which serves for the
following discharge.
The lower part of the tube d¹ may be provided with a bell for enabling the
quantity of air supplied to the siphon S to be augmented.
For ensuring a regular operation and feeding the parts with clean water, I may
also arrange above the compartment 1 of the vessel A a cock a connected to the
main water supply pipe and allowing the flow of a small current of water in a
constant manner. The supply of this cock may be augmented by the action of a
float situated in the vessel B so as to produce as rapid a delivery as possible when
the latter is full.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
:―
First. An apparatus for automatically delivering night-soil, rain water, slops and
the like to drains or sewers, comprising a vessel B into which the night-soil or the
like passes through a waste pipe C, and ordinary water through a reservoir M
having a float, the said reservoir receiving the water from a cock r and conducting
it to the vessel B through a small siphon m, substantially as set forth.
Second. An apparatus for automatically delivering night-soil, rain water, slops
and the like, to drains or sewers, comprising a closed vessel constantly supplied
with water and from the bottom of which extends a siphon S arranged in such a
manner that when the level of the liquid rises in the said vessel the air is compressed
in the siphon S, forces the liquid from the bent portion S¹ of this siphon, and is
precipitated with it into the drain or sewer, which, owing to the rapid rise of the
liquid into the upper part of the siphon S, causes the latter to act so as to completely
empty the vessel. substantially as set forth.
Third. In apparatus for automatically delivering night soil rain water, slops and
the like the employment of a water supply reservoir having a cock with two plugs
and, the first allowing the constant flow of water and the second being opened
only when its float is raised by the rising of the level in order to effect a rapid
delivery by a sudden increase in the flow of water.
Fourth. In an automatic apparatus for the direct delivery of night soil the
combination of a device for operating the siphon S, consisting of a receptacle A
with two compartments 1 and 2 separated by a perforated partition and into which
project the branches dd' of a tube at the top of the siphon S, in combination with
a small siphon J the top of which is lower than that of the siphon S, so that, when
the level reaches a certain height in the vessel B and consequently in the
receptacle A communicating with it, the siphon J is set in action, empties
the compartment 1, allows the escape of the air which remains at the top of the
siphon S which begins to act immediately and empties the vessel B as described
with reference to Figure 4.
