PIPES AND
"
THEIR CONNECTIONS AND APPARATUS FOR THAT PURPOSE [cominu-
nicated to him from Abroad by Frederick Coney of Antwerp in the Kingdom of
Belgium]
This invention relates to the jointing of lead or other soft metal pipes to one
another and to connections such as nozzles or stop-cocks. For jointing together
two lengths of pipe, an externally screwed ring is placed on the one length and an
internally screwed socket with an internal washer is placed on the other length, in
each case at a little distance from the end. The mouth of each pipe is then opened.
out by inserting a conical tool, and the lip is bent farther out and turned over the
ring as a narrow flange by striking it with the shoulder of the conical tool. The
two lengths of pipe being now brought together, the socket which can turn freely
on the one is screwed on to the screwed ring on the other, and thus the outturned
lips are squeezed together making a tight joint. When a lead or soft metal pipe
has to be jointed to connections such as a stop-cock, a nozzle, bend or T piece,
made of brass, iron, or other hard metal, the socket and its washer are applied as
described to the soft metal pipe, and the socket is screwed on to the connection.

THOMAS PERCEVAL WILSON of N° 3. Whitehall Place Westminster in the County

This invention relates to the jointing of lead or other soft metal pipes to one
another, and to connections such as nozzles or stop-cocks. For jointing together
two lengths of pipe, an externally screwed ring is placed on the one length, and an
internally screwed socket with an internal washer is placed on the other length, in
each case at a little distance from the end. The mouth of each pipe is then opened
out by inserting a conical tool, and the lip is bent farther out and turned over the
ring as a narrow flange by striking it with the shoulder of the conical tool. The
two lengths of pipe being now brought together, the socket which can turn freely
on the one is screwed on to the screwed ring on the other, and thus the outturned
lips are squeezed together, making a tight joint. When a lead or soft metal pipe
has to be jointed to connections such as a stop-cock, a nozzle, bend or T piece,
made of brass, iron, or other hard metal, the socket and its washer are applied as
described to the soft metal pipe, and the socket is screwed on to the connection.
Fig. 1 of the accompanying drawings is a longitudinal section shewing two
lengths of lead pipe jointed together according to this invention; Fig. 2 shews in
section separately the three parts of which the joint is made up, and Fig. 3 repre-
sents the tool employed for preparing the ends of the pipes. The ends of the two
pipes being cut square, the socket B and ring A are put on the one and the sleeve C
on the other. The conical end of the tool Fig. 3 is then driven into the mouth of
each pipe so as to expand it. The ring A and the sleeve C being then held up
against the expanded ends of the pipes respectively, the tool Fig. 3 is driven into
them in an inverted position, so that its shoulder D sets the edges over in the form
of the lips or flanges shewn in Fig. 1, whereupon the socket B being screwed on
the sleeve C, these lips are pressed firmly together, so as to form a tight joint.
When a single pipe is to be jointed to a cock or other hard metal connection on
which there is a screw thread corresponding with that on the sleeve C, the joint is
made by giving the lip to the lead pipe and screwing B on the end of the cock or
other connection.
Having thus described the nature of this invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent, I
claim
The herein described method and apparatus for jointing lead or soft metal pipes..
In Witness whereof I the said Thomas Perceval Wilson have hereunto set my
hand and seal tliis Thirteenth day of December in the year of our Lord. One
thousand eight hundred and eighty-three
