Arrangement for Discharging the Sewage of Towns Situated in
Plains.
I, KOLOMAN V. FARKASS of Budapest, Hungary, Royal Chief Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an arrangement for removing the sewage which collects
in the collecting pits of the several parts of a town and which is to be conducted
by means of pipes to certain places where it is either disinfected or
economically utilised.

The essence of this invention consists in providing next to the collecting pit of
each part of the town, a pumping pit in which is arranged a rotary pump that is
preferably driven by means of an electric motor. The electric motors of the several
pumps are supplied with electric current only when the level of the sewage flowing
into the collecting pit has reached a certain height, in which case the electric motor
is then automatically included in the circuit and drives the pump and forces the
accumulated sewage through the delivery pipes to the place of discharge until the
level of the sewage in the collecting pit has fallen again below the height of
contact.

The pump a which is erected (for the purpose of becoming automatically filled)
below the line of the lowest water level in the collecting pits, is driven by the
electric motor b only when the level in the collecting pit B has risen beyond a
certain height which must however, always be below the lowest collecting passage A
that discharges into the pit. This is effected by means of the following arrange-
ment:-In the collecting pit B there is arranged a float c which operates to turn
by means of the mechanisin d e f the contact crank h of the starting resistance g
which is provided in the pump pit, in such a manner that the higher the level rises
in the collecting pit the greater will be the resistance inserted between the line F
and the motor b, the arrangement being such that the contact crank h comes in
contact with the contacts 1-4 (see Figure 3). When the level is below the proper
height, the crank h is not in contact with any of the contacts; the motor b is out of
operation, and the pump is at rest. In order that, in case of a breaking down of
the pump a or of the motor b, the level in the collecting pit shall not rise beyond
a predetermined maximum, it is advisable to arrange in the pump pit a reserve or
duplicate pump a¹ and a reserve or duplicate motor 61 which is inserted or included
in the line F only when the crank h comes in contact with the contacts I-IV, which..
will be the case when the level in the collecting pit rises beyond the normal working
height

electrical signalling lines from all the collecting pits of the town to the central
station so as thereby to enable notice to be given of the fact that a certain level in
the several collecting pits B has been exceeded. The electric motors 6 of the several
pump pits may also be arranged to be included in the line, in such a manner that
they shall not be set in operation automatically but shall be started by hand from
the central station only after the above mentioned transmission of signals. Further,
the connections may be such that the motors b shall be set in operation automatically
and that only the duplicate motors 61 in reserve shall be set in operation from the
central station, when the latter has been signalled that such a step is considered
necessary. In this case the starting apparatus g is provided only with the
contacts 1-4.
Arrangement for Discharging the Sewage of Towns Situated in

I, KOLOMAN V. FARKASS of Budapest, Hungary, Royal Chief 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 an arrangement for removing the sewage which collects
in the collecting pits of the several parts of a town, and which is to be conducted
by means of pipes to certain places where it is either disinfected or can be
economically utilised. .
The essence of this invention consists in providing next to the collecting pit of
each part of the town, a pumping pit in which is arranged a rotary pump that is
preferably driven by means of an electric motor. The electric motors of the several
pumps are supplied with electric current only when the level of the sewage flowing
into the collecting pit has reached a certain height, in which case the electric motor
is then automatically included in the circuit and drives the pump and forces the
accumulated sewage through the delivery pipes to the place of discharge until
the level of the sewage in the collecting pit has fallen again below the height of
contact.
Referring to the drawings lodged with my provisional specification, Figure 1 is
a plan showing the arrangement of the sewers, and Figures 2 and 3 are diagrams
illustrating the construction of the pits.
The sewage of the several parts of the town flows through the downwardly
sloping or inclined pipes or passages A into the collecting pit B next to which is
arranged the pump pit C. The pump mounted in the same, conveys the sewage
through the delivery pipe D to the desired place of destination. The several
electric motors receive their current from the central station E by means of the
line F.
The pump a which is erected (for the purpose of being automatically filled) below
the line of the lowest water level in the collecting pits, is driven by the electric
motor b only when the level in the collecting pit B has risen beyond a certain
height which must however, always be below the lowest collecting passage A that
discharges into the pit. This is effected by means of the following arrangement:-
In the collecting pit B there is arranged a float c which operates to turn by means

provided in the pump pit, in such a manner that the higher the level rises in the
collecting pit the greater will be the resistance inserted between the line F and
the motor b, the arrangement being such that the contact crank comes in contact
with the contacts 1-4 (see Figure 3). When the level is below the proper height,
the crank is not in contact with any of the contacts; the motor b is out of
operation, and the pump is at rest. In order that, in case of a breaking down of
the pump a or of the motor b, the level in the collecting pit shall not rise beyond
a predetermined maximum, it is advisable to arrange in the pump pit a reserve or
duplicate pump al and a reserve or duplicate motor 61 which is inserted or included
in the line F only when the crank h comes in contact with the contacts I-IV, which
will be the case when the level in the collecting pit rises beyond the normal working
height.
For the purpose of controlling the entire arrangement, it is advisable to provide
electrical signalling lines from all the collecting pits of the town to the central
station so as thereby to enable notice to be given of the fact that a certain level in
the several collecting pits B has been exceeded. The electric motors b of the
several pump pits may also be arranged to be included in the line, in such a
manner that they shall not be set in operation automatically but shall be started
by hand from the central station only after the above mentioned transmission of
signals. Further, the connections may be such that the motors b shall be set
in operation automatically, and that only the duplicate motors 61 in reserve
shall be set in operation from the central station, when the latter has been signalled
that such a step is considered necessary. In this case the starting apparatus g
is provided only with the contacts 1-4."
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
claim is
(1) An arrangement for removing the sewage of towns situated in plains,
characterised by the fact that next to each of the several collecting pits B of the
sewers, there is provided a pumping pit C in each of which there is provided a
rotary pump a, adapted to discharge the sewage, and an electric motor b adapted
to drive said rotary pump, in such a manner, that the several motors of the pump
pits can be included automatically in the current circuit F connected to the central
station E either by means of the rise of the level of the sewage in the collecting
pit B by the action of the float e and of the starting resistance g; or can be started
by hand from the central station on the receipt of automatically transmitted signals,
as set forth.
(2) In the arrangement specified in Claim 1, a starting device g in which on the
rise of the level above a certain maximum the float c turns the contact crank h
(that serves to start the pump a) in such a manner that the said crank in rubbing
over the contacts I-IV acts to start the auxiliary motor 61 that operates the reserve
pump a¹, as set forth.
