CHARLES JORDAN, of Newport, in the County of Monmouth. IMPROVEMENTS
IN JOINTS FOR CONNECTING PIPES OR TUBES FOR GAS, WATER, OR OTHER
PURPOSES."
This Invention relates to improvements in the method of making joints for con-
necting pipes or tubes for gas, water, or other purposes.
It is well known that when molten lead is used for filling the space in the socket
around the end of the pipe it is connected to that when the lead is cold and set the
shrinking of the metal causes a space to be left between it and the surfaces of the
pipes, an imperfect joint being the result, which it is difficult afterwards to close
and make perfectly tight.
Now according to my Invention I first cast the filling piece of lead or its alloys
or other comparatively soft metal in the form of a bush or ring in cast iron,
wrought iron, steel, or other "chill" moulds. This bush or ring is then inserted in
the socket or placed on the end of the pipe or tube to form the joint, and the two
parts being made to fit tightly are then forced or drawn together so as to compress
the bush or ring of lead or soft metal between the two ends of the pipes or tubes,
and thus form a perfectly tight joint.
In the case of small pipes or tubes they may be forced together by means of
a sledge hammer or otherwise, and for larger pipes they may be formed with lugs
on the socket, a wrought-iron or metal gland being placed across the socket of the

page_text: pipe to be connected, which is forced into place by means of screw bolts connected
to the lugs and to the gland, or otherwise.
The bush or ring may be formed with an inclined passage through it so as to
admit of the pipes being set or jointed at an angle to each other.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Jordan in the Great Seal Patent Office on the 12th July

"IMPROVEMENTS
IN JOINTS FOR CONNECTING PIPES OR TUBES FOR GAS, WATER, OR OTHER
PURPOSES."
This Invention relates to improvements in the method of making joints for con-
necting pipes or tubes for gas, water, or other purposes.
It is well known that when molten lead is used for filling the space in the socket
around the end of the pipe it is connected to that when the lead is cold and set the
shrinking of the metal causes a space to be left between it and the surfaces of the
pipes, an imperfect joint being the result, which it is difficult afterwards to close
and make perfectly tight.
Now according to my Invention I first cast the filling piece of lead or its alloys
or other comparatively soft metal in the form of a bush or ring in cast iron, wrought
iron, steel, or other "chill" moulds. This bush or ring is then inserted in the
socket or placed on the end of the pipe or tube to form the joint, and the two parts
being made to fit tightly are then forced or drawn together so as to compress the
bush or ring of lead or soft metal between or around the two ends of the pipes or
tubes, and thus form a perfectly tight joint.
In the case of small pipes or tubes they may be forced together by means of a
sledge hammer, or otherwise, and for larger pipes they may be formed with lugs on
the socket, a wrought-iron or metal gland being placed across the socket of the pipe
to be connected, which is forced into place by means of screw bolts connected to the
lugs and to the gland, or otherwise.
The bush or ring may be formed with an inclined passage through it so as to
admit of the pipes being set or jointed at an angle to each other.
And in order that my Invention may be clearly understood and readily carried
into practice I will proceed to describe the Drawings hereto annexed,
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a longitudinal section of the ends of two straight metal nines

page_text: Figure 3 shows a section of the socket end of a pipe with a metal cap e placed
thereon, and a block of wood d to receive the blows of a sledge hammer for driving
the spigot end of one pipe into the socket end of another pipe.
Figure 4 shows an end view of the driving cap c and block of wood d.
Figure 5 shows a section of two curved metal pipes a, a, connected together in
accordance with my Invention.
Figure 6 shows an elbow pipe a with bush b.
In carrying out my Invention I bore out the socket end of each pipe a and turn
the spigot end slightly conical. An annular cone or bush of lead b, or other soft
metal or allow (cast in a chill mould), is inserted and driven into the socket end of
the pipe, and the spigot end of the adjoining pipe is introduced into the leaded
socket, and is driven in by means of a mallet if the pipes are of comparatively small
diameter, but for larger pipes a cap c and block of wood d is placed over the end of
the socket pipe, which is then driven home by means of a sledge hammer or other-
wise.
When the pipes are curved or bent, brackets or projections are cast upon them,
as shown at a, a¹, Figures 5, 6, and 7, for the purpose of driving them into
position, a piece of wood being placed in front of the projection for the hammer to
act upon, and thus prevent the pipes from being broken when being forced into
each other. The snugs or projections a¹ are so placed as to cause the force of the
blow to act in a direct line with the centre of the joint.
Figure 7 shows a method of connecting two pipes in case of breakage, or for con-
necting my improved joint with ordinary socket pipes. In this case the pipe a is
formed with a socket at each end, the socket a² at one end being much longer than
the socket at the other end. The pipe b is formed with a spigot at each end, so
that when the end 61 is driven into the socket of the adjoining pipe the end 62 slides
in the elongated socket of the other adjoining pipe a, which joint is rendered tight
by running lead therein and caulking in the ordinary manner.
Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, I would remark that I make no claim to any of
the parts separately, which are well known and in common use; but what I claim
is, the improved method of making joints for connecting pipes or tubes for gas,
water, or other purposes by means of a soft metal bush b, introduced between the
two ends of the pipes to be connected, substantially in the manner herein-before
described, and represented in the Drawings hereto annexed.
In witness whereof, I, the said Charles Jordan, have hereunto set my hand
and seal, this Eighth day of June, in the year of our Lord One thousand
eight hundred and seventy-eight.
