PROVISIONAL SPECIFICATION.
An Improved Appliance for Use in Cleansing Outlet Pipes for
Waste Liquids, such as the Sink Pipes of Kitchens and the like.
I JOHAN ERIK ANDERSON of 25-27 Döbelnsgatan Stockholm in the Kingdom
of Sweden, Gentleman do hereby declare the nature of this invention to be as
follows:-
-
This invention consists of the improved appliance hereinafter described for use
in clearing dirt and fatty matter and other deposits from the outlet pipes of
kitchen sinks and other outlet pipes where a supply of water under pressure is
available.
The said improved appliance consists of two lengths of pipe connected end to
end by means of a screw socket so that by turning one of the said lengths of pipe
it may be caused to advance towards or recede from the other. The outer or free
end of one of the said lengths of pipe is provided with packing or is so formed
that when pressed against the mouth of a water supply tap of ordinary size a
water tight connection may be produced between the said pipe and tap. On the
other length of pipe is placed a tubular plug the interior of which is of cylindrical
or conical form and the exterior of which is of spherical or hemispherical or conical
form and of such size that a water tight joint or connection may be formed by it
between the pipe on which it is placed and a sink pipe of any ordinary size by
pressing the said plug against the mouth of such pipe.
In using the said appliance the length of pipe which is adapted for connection
to the supply tap is turned in the connecting socket until the proximate ends of
the two connected lengths of pipe are in contact the length of pipe on which the
plug is placed is passed into the sink pipe or other pipe to be cleared and turned
in the connecting socket until the free end of the other length of pipe is pressed
against the tap of the water supply. By this means a water tight connection is
produced between the water supply tap and the outlet pipe to be cleared the
clearing of which pipe is effected on opening the said tap by means of the water
under pressure which is thus admitted to the said outlet pipe from the water
supply.

COMPLETE SPECIFICATION.
An Improved Appliance for Use in Cleansing Outlet Pipes for
Waste Liquids, such as the Sink Pipes of Kitchens and the like.
I JOHAN ERIK ANDERSON of 25-27 Döbelnsgatan Stockholm in the Kingdom
of Sweden Gentleman 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 consists in the improved appliance hereinafter described and

page_text: illustrated in the accompanying drawings for use in clearing dirt and fatty matter
and other deposits from the outlet pipes of kitchen sinks and other outlet pipes
where a supply of water under pressure is available.
Figure 1 of the accompanying drawings is a longita linal section and Figure 2
is a plan of one form of the said appliance.
Figures 3 and 4 illustrate alternative forms of a part thereof.
The said appliance consists of a lower pipe a having connected to it a socket
into which is screwed the upper pipe e which pipe may be picked at its upper
end suitably to form a watertight junction with the tap of a water supply pipe.
On the lower pipe a is a plug d which is shaped like a truncated come the smaller
cnd being downward. The bore of the cone which takes on the pipe is larger at the
bottom than at the top to allow of the said pipe being put in a slanting position
when necessary. The conical shape of the plug a may be exchanged for or
modified into the spherical shape shown in Figure 3 or the hemi-spherical shape
shown in Figure 4 which shapes of the said plug dalimit of the central orifice or
bote being made of the same diameter throughout.
The action of the said appliance is as follows:-The upper pine is serenel
down as low as possible into the socket after which the plug is plast with its
smaller end downward on the lower pipe which is of such length as to nearly
reach the bottom of the outlet pipe. The said pipe a is then lowered into the
outlet pipe and is screwed on the upper pipe e until the latter fits tightly onto
the tap of the service pipe and watertight joints are maile between the service pipe
and the said appliance and the outlet pipe. The tap of the water supply is now
opened and the water flows under pressure through the outlet pipe and washes
and carries away the dirt and fatty matter.
Figures 5 and 6 illustrate in longitudinal section and plan respectively an
alternative arrangement for securing the plug off on the lower pipe t Referring
to the said figures is an elastic india rubber ring placed around the said lower
pipe a the height or position of which ring is capable of being adjuste 21 N required.
When the plug d is on the said pipe a and the upper pipe e is screwed thereon the
anid plug is pressed against the ring e and thereby prevented from shifting.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
An appliance for use in cleansing the outlet pipes of kitchen sinks and the like
consisting of a lower pipe a of such dimensions as to be capable of passing nearly
to the bottom of the cutlet pipe and having at top a socket provided with a
screw thread in which screw thread an upper pipe is screwed the said lower
pipe a being provided with a plug d of conical or spherical or hemi-spherical shape
or form.
