PROVISIONAL SPECIFICATION.
Improved Means for Connecting Metal Pipes to the Basins or Traps
of Water Closets, Slop Sinks, Urinals, and other similar Sanitary
Appliances.
I THOMAS ROBINSON of 127 Ramsden Road Wardle in the County of
Lancaster Plumber do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved means for making a perfect air and liquid
tight joint between the earthenware outlet pipe of the water closet basin, slop-sink,
urinal or other similar sanitary appliance made of earthenware, and the leaden or
other metal soil or waste pipe connecting the same with the drain, and to enable
such joint to be readily made and closed again when required for repairs or
otherwise.
The invention is an improvement upon the invention for which I made application
for Letters Patent (with a Complete Specification) bearing date March 12th 1892
and numbered 4871. The objects of the present improvements being to dispense
with the necessity for turning and grinding the surfaces of the conical ring and
socket together so as to make a perfect joint, and also in some cases to avoid the
necessity for soldering the conical ring or socket onto the end of the leaden or other
metai soil or waste pipe.
For the purposes of my present invention I provide an outside metal ring which
slips over the inside metal ring, and the top end of the lead or other soft metal
soil or waste pipe. This outer ring is formed with a lip at the top over which the
top end of the lead pipe is lipped or turned.
The lead pipe passes up between the outside ring and inside cone and between
the top of the outside ring and a flange or socket made at the top of the inner ring
which latter is cemented or fixed to the earthenware outlet pipe as described in the
Specification before referred to, and a washer of india rubber or other yielding
material is placed between the two rings, so that when the flat ring or collar.
(in two parts) is bolted on, a perfectly air and liquid tight joint will be made.
When the soil or waste pipe is made of cast iron I make the outer ring deeper
and form a groove or socket all round the lower edge to receive the top of the cast
iron pipe, and I fix the same therein.
In cases where it is required to connect a soil or waste pipe of a comparatively
small diameter to an earthenware outlet of a larger diameter I make the connection
in a similar way, but instead of bringing the top of the lead pipe up between the
two conical metal rings and turning or lipping its edge over I fix on the top of
the pipe a cast lead socket made in a splayed form and provided with a projecting
ring near the top against which the loose metal ring can abut and press it up into
position so as to form the joint.
And in some cases where it is desired to connect a lead or other metal waste pipe
with the earthenware outlet of a slop sink or lavatory basin provided with a conical
metal plug I make the connection in a similar manner with the addition that the
cone turns up inside the outlet pipe to receive a conical seating for the plug.
This seating is made with two projections to engage with two L-shaped slots in
the cone, so that when slipped into place and partly turned round they will make
a secure joint which can be easily unclosed by a partial turn back again.
The projections and slots are made of a dovetail shape so as to cause them to
lock firm.

Improved Means for Connecting Metal Pipes to the Basins or Traps
of Water Closets, Slop Sinks, Urinals, and other similar Sanitary
Appliances.
I THOMAS ROBINSON of 127 Ramsden Road Wardle in the County of
Lancaster, Plumber, 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 :-
1
This invention relates to improved means for making a perfect air and liquid
tight joint between the earthenware outlet pipe of a watercloset basin, slop sink,
urinal or other similar sanitary appliance made of earthenware, and the leaden or
other metal soil, or waste pipe connecting the same with the drain, and to enable
such joint to be readily made and closed again when required for repairs or
otherwise. The same also applicable as a means for lengthening the metal. soil
or waste pipes.
The invention is an improvement upon the invention for which I obtained Letters
Patent bearing date March 12th, 1892 and numbered 4871, the objects of the present
improvements being to dispense with the necessity for turning and grinding the
surfaces of the conical ring and socket together so as to make a perfect joint, and
also in some cases to avoid the necessity for soldering the conical ring or socket
onto the end of the leaden or other metal soil or waste pipe.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a section illustrating one modification.
For the purposes of my present invention provide an outside metal ring a
which slips over the inside metal ring and the top end of the lead or other soft
metal soil or waste pipe c. This outer ring a is formed with a lip a' at the top over
which the top end of the lead pipe is lipped or turned. The lead pipe c passes
up between the outside ring a and inside cone and between the top of the outside
ring a and a flange or socket made at the top of the inner ring 6 which latter is
ceniented or fixed to the earthenware outlet pipe d, as described in the Specification
before referred to, and a washer of india rubber or other yielding material may be
placed between the two rings a and b so that when the flat ring or collar (in two
parts) e e¹ is bolted on, a perfectly air and liquid tight joint will be made.
When the soil or waste pipe cis made of cast iron I make the outer ring a deeper,
as shown at Fig. 2; and form a groove or socket fall round the lower edge to
receive the top of the cast iron pipe c and 1 fix the same therein, by means
of pins or screws f³, or the outer rim of the socket may be dispensed with, and
the conical ring a be fixed to the cast iron pipe e by soldering or by screwing as
shown at Fig. 3.
In cases where it
required to connect a soil or waste pipe of a comparatively
small diameter to an earthenware outlet of a larger diameter I make the connection
in a similar way to Fig. 1 but instead of bringing the top of the lead pipe c
between the two conical metal rings a and b and turning or lipping its edge over f.
fix on the top of the pipe a cast lead socket g made in a splayed form and provided
with a projecting rim near the top against which the loose metal ring a can abut
and press it up into position so as to form the joint. (See Fig. 4.)
And in cases where it is desired to connect a lead or other metal waste pipe with
the earthenware outlet of a slop sink or lavatory basin provided with a conical metal
plug I make the connection in a similar manner (as shown at Fig. 4) with the
addition that the cone 6 turns up inside the outlet pipe d to receive a conical
seating for the plug i. This seating is made with two projections k to engage
with two L-shaped slots in the cone 6 as shown detached at Fig. 5 so that when

page_text: slipped into place and partly turned round they will make a secure joint which can
be easily unclosed by a partial turn back again.
The projections and slots are made of a dovetail shape so as to cause them to
lock firm it will be evident that this same arrangement can be used without the
plug i.
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 :-
:-
The improved means for connecting metal pipes to the earthenware basins or
traps of waterclosets, slop sinks, urinals, and other similar sanitary appliances
substantially as hereinbefore described and illustrated by the drawings annexed.
