Improved Means for Connecting Metal Pipes to Earthenware Drain
.
Pipes, Water Closet Basins or Traps, applicable also to the
Connection of other Metal Pipes for similar purposes.
I, THOMAS ROBINSON, Plumber 127 Ramsden Road Wardle Lancashire do
hereby declare the nature of this invention to be as follows :-
The object of this invention is to construct a permanent air and water tight joint
between a lead soil, or waste pipe and a drain pipe or water closet basin or trap
made of earthenware applicable also for joining two metal pipes together.
When connect the lead soil or waste pipe to an earthenware drain pipe I form
a short earthenware pipe with a projecting rim formed all round the top edge, and
into this pipe I insert a lead pipe or cap formed with a groove or socket all round
the top thereof and bed it in a suitable cement and turn the lead over the bottom
edge and insert it into the socket of the drain pipe and cement it thereto and solder
the lead pipe to the top edge thus forming a permanent air and water tight joint.
When it is required to fix the lead pipe to the outlet of the water closet, I form
on the inside of the outlet pipe a projecting hollow shoulder and I insert the short
earthenware pipe therein and connect it as described above.
When it is required to fix the lead pipe to the outlet of an ordinary water closet
basin or trap, I form the short earthenware pipe to fit on the outside and turn the
lead over the top and bottom and edge and connect as above described.
In cases where it is required to connect a lead to an iron socket pipe, I dispense
with the short earthenware pipe, and I form a lead or brass pipe or cap similar in
shape to the metal pipe or cap described above and I insert it into and over the top
edge of the iron pipe socket, and fill the intervening space with a suitable cement
or metallic lead, and solder the lead pipe thereto.
It will be evident that although I describe the metal pipe or cap as a detached
piece of metal it may be constructed as a continuation to any length of pipe or a
loose socket or collar may be placed over the pipe and attached thereto by
soldering,'
," "burning," or casting."

COMPLETE SPECIFICATION.
Improved Means for Connecting Metal Pipes to Earthenware Drain
Pipes, Water Closet Basins or Traps, applicable also to the
Connection of other Metal Pipes for similar purposes.
I, THOMAS ROBINSON of 127 Ramsden Road, Wardle Plumber in the County
of Lancaster 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 :---
The object of this invention is to construct a permanent air and water tight join

page_text: between a lead soil or waste pipe and a drain pipe or water closet basin or trap,
made of earthenware, applicable also for joining two metal pipes together.
The nature of my 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. shews a sectional elevation of my invention as applied to the connection
of the metal pipe, to a drain pipe: Fig. 2. and 3. shews a similar view as applied to
a water closet basin or trap outlet: Fig. 4. shews the application of my invention
to the connection of metal pipes.
In the first place when I connect the lead soil or waste pipe, a, Fig. 1, to the
earthenware drain pipe, a 1, I form a short earthenware pipe, a 2, with a projecting
rim formed all around the top edge, a 3, and 1 insert a lead pipe or cap, b, formed
with a groove or socket 1, all around the top thereof, into the short earthenware
pipe, a 2, and bed it in a suitable cement (preferably white lead) and turn the lead
over the projecting rim, a 3, and over the bottom edge, a 4, and I insert it into the
drain pipe, a 1, and cement it thereto, and attach the lead pipe, a, to the top edge
of the lead pipe or cap, bi, by ("soldering or burning") thus forming a
permanent air and water tight joint.
ני
When I connect the lead pipe to the outlet of a water closet basin or trap, I form
on the inside of the outlet pipe 62, Fig. 2, a projecting hollow shoulder, 63, and I
insert a similar short earthenware pipe as shown at a 2, (Fig. 1) therein and connect
thereto as described at a 1, Fig. 1.
When I connect the lead pipe, a, Fig. 3, to the outlet of an ordinary water closet
basin or trap as shown at c, Fig. 3, I form the short earthenware pipe, e 1, to fit on
the outside of the outlet of the water closet basin or trap, c, and I fix the lead pipe.
or cap, e 2, on the outside of the short earthenware pipe, c 1, and turn the lead over
the top and bottom edge inwardly and connect it to the outlet, c, by cement, and
attach the lead pipe, a, as described at 6 1, (Fig. 1).
In cases where it is required to connect the lead pipe, a, Fig. 4, to an iron socket
pipe, d 2, as shown at Fig. 4, (I dispense with the short earthenware pipe, a 2,
Fig. 1, and, e 1, Fig. 3) and 1 form a lead (or brass) pipe or cap, d 1, similar in
construction to the lead pipe or cap described at, b, (Fig. 1) and I insert it into and
over the socket, d, of the iron pipe, d2, and I fill the intervening space, between
the pipe, or cap, d'1, and the iron socket, d, with a suitable cement, or molten lead,
and attach the lead pipe, a, to the top edge, or rim, as described at 61 (Fig. 1).
It will be evident that although I describe the metal pipe or cap, (as shown at b,
Fig. 1, and 2, Fig. 3, and d, Fig. 4) as a detached piece of metal, it may be
constructed as a continuation to any length of pipe as shown for example at d2,
Fig. 5, or a loose collar or socket, d4, Fig. 5, may placed over the pipe ee,
and attached thereto by "soldering" "burning," or "casting."
Having now particularly described and ascertained the nature of my said iuven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1st. The improved means for permanently connecting metal pipes, to drain pipes,
or water closet basins or traps, made of earthenware, substantially as hereinbefore
described, and illustrated by the drawings annexed.
2nd. The improved means for permanently connecting metal pipes together,
substantially, as hereinbefore described and illustrated by the drawings annexed.
