Improvements in Pipe Joints or Connections.
I, THOMAS CARTMAN, of No. 1, Cheltenham Crescent, Harrogate, in the County
of York, Registerd Plumber, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to make a cheap and secure joint between pipe
made of lead or other pliable material and pipe made of iron, brass, earthenware
or other hard material.
In order to accomplish this I employ a socket of iron, brass or other suitable
material which may be of equal diameter throughout its length or greater
diameter at one end than the other. The pipe of lead or other pliable material
is passed through the socket (at the smaller end if one of varying diameter be
used) and turned back outside thus forming a lining to the socket a small flange
may be provided on the outside of the outward end of the socket and if the
internal pipe be turned back and over this it would prevent the socket slipping
backward. The socket is made large enough to be passed, together with its
lining over the pipe to which it is to be connected and leave a small space be-
tween the two which is filled with suitable cement thus making a secure joint.
Hitherto the pipe of lead or other pliable material has been enlarged (when
necessary) to allow it to pass over the pipe of harder material to which it was
to be connected and the space between filled with cement but any vibration of
the parts has caused the pliable pipe to give or open thus causing a leak. By
using the socket as herein described the cement used can be caulked tightly in
and a more secure joint made. This invention will be of great advantage in
sanitary work.
Sockets have been used previously in this work but a soldered joint has been
necessary to connect them to lead pipe which in this case is dispensed with.
The socket being entirely lined is protected from corrosion if made of a
corrosive material.
When sockets of varying diameters are used the pliability of the lining
allows it to be adapted thereto.

page_text: 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 make a cheap and secure joint between pipe
made of lead or other pliable material and pipe made of iron, brass earthenware
or other hard or rigid material.
In order to accomplish this I employ a socket of iron brass or other suitable
rigid material which may be of equal diameter throughout its length or of greater
diameter at one end than the other. The pipe of lead or other pliable material
is passed through this said socket (by way of the smaller end if of varying
diameter) and its edges turned backwards outside the socket thus forming. a
lining thereto. A small flange may be provided on the outside of the outward
end of the socket and if the end of the internal pipe be turned backwards over
this it would prevent the socket slipping backwards or forwards. The said socket
is made large enough to be passed easily, together with its lining, over the pipe
of iron, brass, earthenware or other hard or rigid material to which the con-
nection is to be made and leave an annular space between which is filled with
suitable cement thus making a secure joint. Hemp may be wrapped round the
rigid pipe before the socket is passed over it to prevent the cement oozing
through the joint. Hitherto the pipe of lead or other pliable material has been
enlarged at the end to form a socket sufficiently large to allow it to be passed
over the pipe of hard or rigid material to which it was to be connected and
leave an annular space between the two which was filled with cement, but any
vibration of the parts has caused the socket thus formed to give or enlarge,
thereby causing the joint to leak. By using a socket of iron, brass or other
suitable rigid material the cement used can be tightly caulked in and a per-
fectly secure joint made. This invention will be of great advantage in sanitary
work. Sockets similar to the one described have been used previously for this
work but a soldered joint has been necessary to connect them to lead pipe which
in this case is dispensed with. The socket herein described being entirely lined
by the pliable pipe is protected from corrosion if made of a corrosive material.
When sockets of varying diameter are used the pliability of the pipe allows it
to adapt itself thereto.
In order to fully illustrate this my said invention I have hereunto annexed a
sheet of drawings in which Fig. 1, is a side elevation of an earthenware closet
basin connected to lead pipe by means of a socket as herein described. Fig. 2, is
an end elevation thereof, and Fig. 3 shews a section of the joint described to a
larger scale.
A is the socket of iron brass or other suitable rigid material (shewn of v ry-
ing diameter) through which a lead pipe B is passed by way of the smaller and
and having its edge turned back over a flange A¹ on the socket A. D is the
hemp which may be used to prevent the cement C being pressed through the
joint. E¹ is the outlet of the earthenware closet basin E to which the lead peis
connected. The other end of the lead pipe is connected to a fall pipe
means of branch pipe G.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that hat
