IMPROVEMENTS IN THE PIPE CONNECTIONS OF EARTHENWARE WATER CLOSET PANS, URINAL BASINS, WASHING BASINS AND SINKS
Year: 1884

page_text: PROVISIONAL, SPECIFICATION.
We JANES KEMP and FERMO FISSI both of the Royal Blind Works, Morval
Road, Brixton in the County of Surrey Builders do hereby declare the nature of
our invention for IMPROVEMENTS IN THE PIPE CONNECTIONS OF EARTHENWARE
WATER CLOSET PANS, URINAL BASINS, WASHING BASINS AND SINKS to be as
follows:-
Hitherto the connection between the tubular inlet arm of earthenware water
closet pans and the supply pipe which has to be fitted thereto has been a plain
joint completed by means of putty and india rubber; and the connection between
the tubular outlet of the pan and the end of the trap or pipe which has to be fitted
thereto has also been a plain joint completed by cement or like material. The
connections at the inlet and outlet of earthenware urinal and washing basins and
at the outlet of earthenware sinks have likewise been plain joints completed in a
similar manner. These joints or connections are wanting in durability and there-
fore soon become leaky and the object of our invention is to make joints and
connections which shall be durable and can also be readily disconnected and
reconnected in case of need.
For this purpose we form the tubular inlet arm of earthenware water closet pans
(and which is in one piece with the pan) with an external screw thread; and we
connect it with the supply pipe by means of what is generally called a "cap and
lining," that is to say the end of the supply pipe enters the tubular arm and then
the parts are connected by means of a union nut which bears against a flange on
the supply pipe and is screwed upon the tubular arm until the face of the flange is
brought tight against the end of the tubular arm, or rather against a washer or
packing placed between the flange and the tubular arm to make a hermetic joint.
We likewise make the tubular outlet of the pan with an external screw thread to
receive a corresponding screw thread on the end of the pipe or trap which has to
be connected thereto and we screw the pipe or trap upon the tubular outlet until
the face of the end of the pipe is brought tight against the bottom of the pan,
a washer or packing being placed between the two to make a hermetic joint.

arms with external threads and employing a cap and lining" and a washer or
packing as above described. In the case of earthenware sinks, we in like manner
make the connection at the outlet by means of a tubular arm (which is in one
piece with the sink) formed with an external screw thread and by employing a

We JAMES KEMP and FERMO FISSI, both of the Royal Blind Works, Morval
Road Brixton in the County of Surrey, Builders do hereby declare the nature of
our invention for "IMPROVEMENTS IN THE PIPE CONNECTIONS OF EARTHENWARE
and in what
WATER CLOSET PANS, URINAL BASINS, WASHING BASINS AND SINKS
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
"
Hitherto the connection between the tubular inlet arm of earthenware water
closet pans and the supply pipe which has to be fitted thereto has been a plain
joint completed by means of putty and india rubber; and the connection between
the tubular outlet of the pan and the end of the trap or pipe which has to be fitted
thereto has also been a plain joint completed by cement or like material. The
connections at the inlet and outlet of earthenware urinal and washing basins and
at the outlet of earthenware sinks have likewise been plain joints completed in a
similar manner. These joints or connections are wanting in durability and there-
fore soon become leaky and the object of our invention is to make joints and
connections which shall be durable and can also be readily disconnected and
reconnected in case of need.
For this purpose we form the tubular inlot arm of earthenware water closet pans
(and which is in one piece with the pan) with an external screw thread and we
connect it with the supply pipe by means of what is generally called a "cap and
lining," that is to say, the end of the supply pipe enters the tubular arm and then
the parts are connected by means of a union nut which bears against a flange on
the supply pipe and is screwed upon the tubular arm until the face of the flange is.
brought tight against the end of the tubular arm, or rather against a washer or
packing placed between the flange and the tubular arm to make a hermetic joint.
We likewise make the tubular outlet of the pan with an external screw thread to
receive a corresponding screw thread on the end of the pipe or trap which has to
be connected thereto and we screw the pipe or trap upon the tubular outlet until
the face of the end of the pipe is brought tight against the bottom of the pan,
a washer or packing being placed between the two to make a hermetic joint.
Figure 1 of the annexed drawings represents in vertical section the pipe con-
nections of an earthenware water closet pan made as above described. a is the
earthenware pan and 6 the tubular inlet made in one piece with the pan; this
inlet is formed with an external thread c as shown. d is the supply pipe entering
the tubular inlet. e is the union nut or cap and lining" which bears against
a flange on the supply pipe and is screwed upon the tubular inlet b until the face
of the flange is brought tight against the washer g placed between the flange and
the tubular inlet. h is the tubular outlet of the pan formed with an external
thread. is the trap or soil pipe which is formed with a corresponding internal
thread and is screwed upon the tubular outlet h until the face of the end of the
trap is brought tight against a washer‘or packing & placed between the trap and
the bottom of the pan,

page_text: In the case of earthenware urinal and washing basins we make the connection
between the tubular inlot and outlet arms thereof (and which are in one piece with
the basin) and the supply and waste pipes respectively by forming the said tubular
arms with external threads and employing a "cap and lining" and a washer or
packing as above described. Figure 2 represents a washing basin and Figure 3 a
urinal basin both having their tubular inlet and outlet arms connected respectively
with the supply and waste pipes in the manner described; these figures will be
readily understood without further explanation.
In the case of earthenware sinks we in like manner make the connection at the
outlet by means of a tubular arm (which is in one piece with the sink) formed with
an external screw thread and by employing a "cap and lining" and a washer or
packing to join it to the waste pipe. This is illustrated in Figure 4 which will also
be readily understood without further explanation.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1. Making the connections between the tubular inlet arms of earthen ware water
closet pans and their supply pipes in the manner shown in Figure 1 and heroin-
before described.
2. Making the connections between the tubular outlet arms of earthenware
water closet pans and the traps or soil pipes in the manner shown in Figure 1 and
herein before described.
3. Making the connections between the tubular inlet arms of earthen waro
washing basins and urinal basins and their supply pipes in the manner shown in
Figures 2 and 3 and hereinbefore described.
4. Making the connections between the tubular outlet arms of earthenware
washing basins and urinal basins and their waste pipes in the manner shown in
Figures 2 and 3 and hereinbefore described.
5. Making the connections between the tubular outlets of earthenware sinks and
their waste pipes in the manner shown in Figure 4 and hereinbefore described.
