of said invention for "IMPROVEMENTS RELATING TO THE EMPTYING OF CESSPOOLS

This invention relates to the emptying of cess-pools or similar receptacles from
a central station by means of a vacuum or compressed air or by a combination of
these two agents, and to apparatus therefor.
. The said apparatus comprises a lever to which is attached a connecting rod
terminating in a valve intended, according to its position, either to open or close
the discharge orifice and thus establish a connection between the cess-pool and a
sewer which conveys the sewage to a general collecting tank situated at the central
station.
In the accompanying drawing I have shown, by way of example, two forms of
apparatus constructed according to this invention.
In the apparatus shown in Figure 1 the discharge orifice is opened by the action
of suction, which raises the valve, while the said orifice is closed by compression,
which, added to the weight of the connecting rod and of the valve, brings the latter
to its seat.
The apparatus consists of a conical holder into which the sewage is conveyed by
an inlet pipe b. An outlet pipe c discharges the sewage into a main sewer d when
the valve e is raised.
The said valve is attached to a connecting rod f connected to the extremity of
the short arm of a lever g having its fulcrum at h on a standard i fixed to the lid j
of the holder a. To the extremity of the long arm of the lever g is jointed a rod k
to which is attached a piston working inside a pipe m.. The said pipe is in
connection with a pipe, which, like the main sewer d, runs to a central station. A
little below the inlet pipe b inside the holder is a grating or metal sieve with
meshes wide enough to let the sewage pass through, but sufficiently close to arrest
the progress of hard and bulky substances, such as bones, broken bottles, and other

the said piston.

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of our invention for "IMPROVEMENTS RELATING TO THE EMPTYING OF CESSPOOLS
OR SIMILAR RECEPTACLES, AND APPARATUS THEREFOR 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 the emptying of cesspools or similar receptacles from a
central station by means of a vacuum or compressed air, or by a combination of
these two agents and to apparatus therefor.
The said apparatus comprises a lever to which is attached a connecting-rod
terminating in a valve intended, according to its position, either to open or close
the discharge orifice, and thus establish a connection between the cesspool and a
sewer which conveys the sewage to a general collecting tank situated at the central
station.
In the accompanying drawing I have shown by way of example two forms of
apparatus constructed according to this invention.
In the apparatus shown in Figure 1, the discharge orifice is opened by the action
of suction, which raises the valve, while the said orifice is closed by compression,
which, added to the weight of the connecting rod and of the valve, brings the latter
to its seat.
The apparatus consists of a conical holder a into which the sewage is conveyed
by a pipe b. An outfall pipe c discharges the sewage into a main sewer & when
the valve e is raised.
The said valve is attached to a rod f connected to the extremity of the short arm
of a lever g, having its fulcrum at h on a standard fixed to the lid j of the
holder a.
To the extremity of the long arm of the lever g, is jointed a rod k to
which is attached a piston 7 working inside a pipe m. The said pipe is in
connection with a pipe which, like the main sewer d, runs to a central station.
A little below the pipe inside the holder is a grating or metal sieve n with
apertures wide enough to let the sewage pass through, but sufficiently close to
arrest the progress of hard and bulky substances, such as bones, broken bottles and
other debris. Above the grating is an opening o through which the said débris can
be removed. This opening is closed by means of a door p. In the centre of the
grating n there is an opening which serves as a guide for the rod f.
The apparatus is very simple in its operation and is worked from the central
station.
To empty the holder a the air is exhausted from the pipe with which the pipe m
is connected. Thereupon the piston is drawn downward thereby rocking the
lever g upon its fulcrum h and causing the rod f and the valve e to rise and open
the outfall opening c. The sewage then passes into the main sewer d, which,
owing to suction now exerted from the central station conveys it to a collecting
tank situated at the said central station.

page_text: As soon as the emptying operation is completed the air in the pipe m is com-
pressed from a central station thereby raising the piston . In its ascent the said
piston lowers the short arm of the lever g and with it also the rod f and the ball
valve e, which again closes the orifice c connecting the holder a with the sewer d.
The apparatus shown in figure 2 differs from the foregoing only in that the rod f
is pivoted to the lever g between the fulcrum and the point where the force is
brought to bear. In this modification the raising of the valve is effected, by means
of compression, while the valve is brought to its seat by creating a vacuum beneath
the said piston.
Apart from this modification the two forms of apparatus are alike.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. The method herein before described of emptying cesspools or similar
receptacles from a central station, the said method consisting in causing a vacuum
and compressed air to alternately act upon a piston or vice versa, to operate,
through the medium of a lever and connecting-rod, a valve which, when open,
places the receptacle to be emptied in communication with a sewer for conveying
away the matter contained in the said receptacle.
Second. The combination with a receptacle a for receiving the sewage from a
drain-pipe, of an outlet pipe c connected to a main sewer d; and a ball-valve e
adapted to be operated, through a rod f attached to a lever g, a rod k and a piston l,
by the alternate effect of a vacuum and compression, or vice versa produced at a
more or less remote central station, in a pipe m, substantially as, and for the
purpose, specified.
