PROVISIONAL SPECIFICATION.
Improvements in Joining or Coupling Lead Pipes to Iron Sockets
or Supports.
..
I FREDERICK GEORGE JONES of 58 Ashmore Road St. Peter's Park,
Paddington, London, Sanitary Engineer do hereby declare the nature of this
invention to be as follows:-
My invention relates to improved means for joining or coupling lead pipes to
iron sockets or supports whereby the ordinary brass coupling and soldered joints is
dispensed with.
According to my invention I form the joint between the lower end of the leaden
pipe and the iron socket or support in which it is held by means of a series of
lead rings fitted loosely on the said pipe which rings form a packing between the
pipe and the inner surfaces of the socket or support. The inside of the lower end
of the pipe is fitted with a thin iron tube or cylinder of about the same depth as
the joint and of sufficient strength to resist the pressure due to the caulking of
the rings and the end of the pipe is slightly bulged to form a bearing surface
between it and the socket. The end of the pipe having been placed in the socket
the aforesaid rings are hammered down or caulked until they entirely fill up the
space between the pipe and the socket thus forming a tight joint, suitable packing
material being preferably placed between the said rings.
To form the joint between two lengths or portions of a leaden pipe and iron
wall-bracket or support the upper end of the lower length is bulged outwards or
enlarged by a bulging tool so as to fit tightly the inner surface of the wall-bracket;
the lower end of the upper length is then placed in the said enlarged portion of
the lower length, the space formed between the two being filled up with molten
lead and caulked so as to form a tight joint. The lower end of the upper length
rests upon a ledge formed around the bottom of the wall-bracket, and a recess may
be formed in the inner wall of the said enlarged portions into which the molten
lead runs and acts as a key thereto.
As my improvements are capable of some modification without departing from
the principle thereof I do not restrict myself to the precise form or placement of
the parts thereof.

Improvements in Joining or Coupling Lead Pipes to Iron Sockets
or Supports.
I FREDERICK GEORGE JONES of 58 Ashmore Road, St. Peter's Park
Paddington in the County of London, Sanitary Engineer do hereby declare the
nature of my 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 relates to improved means for joining or coupling lead pipes to
ГД...

page_text: iron sockets or supports whereby the ordinary brass coupling and soldered joints
are dispensed with.
According to my invention I form the joint between the lower end of a lead
pipe and its iron socket or support by means of two or more lead rings fitting round
the said end, the said rings forming a packing between the pipe and the inner
surface of the socket or support.
The inside of the end of the pipe is fitted with a thin iron tube for enabling
the pipe to resist the pressure necessary for caulking the said rings, and the said
end is slightly bulged to form a bearing surface between it and the socket.
The said rings are hammered down or caulked until they fill up the space
between the pipe and the socket suitable packing material being previously placed
between the rings.
To form a joint between two lengths of a lead pipe and an iron wall bracket
or support the upper end of the lower length is bulged out or enlarged to fit the
inner surface of the wall bracket, the lower end of the upper length is then placed
in the said enlarged end of the lower length and the space formed between the two
filled up with molten lead and caulked thus forming a tight joint. A recess may
be formed in the inner wall of the bracket, and consequently in the lead pipe fitted
thereto, into which the molten lead runs so as to act as a key to the said lead.
According to a modification for forming a joint between a lead pipe and a socket
forming the end of an iron pipe I extend the latter a short distance within the
socket and fit around it a loose leaden tube, I then partially fill up the space
between the latter and the socket with molten lead the remaining space being
filled up with a wooden ring formed with a flange bearing against the outer end of
the socket. The end of the leaden tube is then bent over and forced against the
outer side of the flange of the said wooden ring. The lead pipe to be joined is
then placed in position against the turned over end of the leaden tube its end being
bevelled so as to fit against a bevelled portion of the said tube. The lead pipe
and leaden tube are then suitably soldered together, thus forming a tight joint.
In the accompanying sheet of drawings illustrating my invention
Figure 1 is a section of my improved joint or coupling, the lower portion
showing the joint formed between the lower end of a lead pipe and an iron socket,
and the upper portion the joint between the upper end of a lead pipe with its
bracket or support, and the lower end of another lead pipe.
Figure 2 shows a modified form of joint.
Figure 3 is a cross section on line of Figure 1 and
Figure 4 a cross section on line y y of Figure 2.
Figure 5 is an elevation of an iron branch pipe with a lead pipe connected
thereto.
a' is the iron socket or support formed on the end of a pipe a¹ and 6 is the lead
pipe to be joined thereto. The end is slightly enlarged to receive the thin iron
tube c which acts as a support to the lead pipe b against the pressure occasioned
by the caulking of the lead rings d carried on the end of the said pipe and the
end of the latter is enlarged or bulged out at b' to form a bearing between it and
the inner end of the socket, e is any suitable packing material placed between the
rings d.
In order to form a joint between the lead pipe 6 and another lead pipe f the
end of the pipe b is bulged out to fit the interior of the wall bracket or support g
of the said pipes. The end of the pipe f bears against the ledge 62 of the
pipe b when placed in position within the bracket g, and the space formed between
the two pipes is then filled up with molten lead h which is caulked to form a
tight joint a recess h being preferably formed into which the lead runs so as to
form a key thereto.
In the modification shown in Figure 2 the end a 2 of the iron pipe a¹ is
extended a short distance within the socket a. Around this end is placed a
loose leaden tube i provided with a flange bearing against the inner end of
the said socket. Having placed the tube i in position molten lead his poured

then caulked to form a tight joint.
The rest of the space is then filled by a wooden ring k provided with a curved
flange bearing against the outer end of the socket a and formed with a bevelled
portion 2. The outer end of the tube i is theu bent over and forced against the
curved surface of the flange after which the lead pipe to be joined is placed
in position so that its bevelled end bears against the bevelled portion of the
turned over tube i.
The pipe is then soldered by solder m to the curved end of the tube i and
the joint is complete.
The wooden ring k is for the purpose of preventing any moisture ascending to
the solder m of the pipe l.
In Figure 5 n is an iron pipe formed with a branch n¹ to the socket n 2 of which
is connected the lead pipe o in manner such as herein before described.
As my improvements are capable of some slight modification without departing
from the principle of this my invention I do not restrict myself to the precise form.
or placement of the parts thereof.
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 ;-
1. In joining or coupling lead pipes to iron sockets or supports the employment
of lead rings surrounding the end of the lead pipe and caulked between the said
pipe and the interior of the socket, substantially as described and for the purpose.
