Improvements relating to Pipe Joints for Water Taps and the like.
We, OCTAVIUS THOMAS, of Laburnum House, Risca, Monmouthshire, Manager
of Gas and Water Works, and JOHN HENRY DYER, of 1, Grove Villas, Ponty-
mister, Monmouthshire, Plumber, do hereby declare the nature of this invention to
be as follows:-
This invention relates to joints for connecting water taps and the like to pipes.
According to this invention as applied to a water tap, the pipe for connection to
the tap is telescoped into a chamber of brass, gun-metal or other suitable metal
which chamber is incorporated with or connected to the tap.
That part of the pipe which is contained within the chamber fits over a ferrule
or tube made in one piece with the chamber and extending along in the middle
thereof. Between the outside of the pipe and the inside of the chamber is a space
which, when the pipe has been slipped over the ferrule or tube, is charged with
solder which is charged in either at the mouth of the chamber or through an
A secure
aperture in the chamber wall, or is otherwise conveniently introduced.
and water-tight joint is thus made and is, by the provision of the chamber, effected
with less solder than heretofore generally used in jointing pipes, and economy also
in time in jointing is effected and the joint is less liable to leak.
In its application to other water fittings than taps the invention is substantially
the same.
The chamber aforesaid is approximately oval, or is globular or of other suitable
shape. As adapted for horizontally disposed pipes the chamber mouth fits the
pipe sufficiently closely to prevent escape of solder at the mouth.
As adapted for vertically disposed pipes the chamber mouth is sufficiently larger
than the pipe to permit the solder to be poured in at the mouth.

Improvements relating to Pipe Joints for Water Taps and the like.
We, OCTAVIUS THOMAS, formerly of Laburnum House, Risca, and now of
Prospect House, Pontymister, Monmouthshire, Manager of Gas and Water
Works, and JOHN HENRY DYER, of 1, Grove Villas, Pontymister, aforesaid,
Plumber, 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 :-
This invention relates to joints for connecting lead pipes to water taps and
other water-fittings.
According to this invention, as applied to a water tap, the lead pipe for
connection to the tap is telescoped into a chamber of brass, gun-metal or other
suitable metal tinned internally. This chamber is incorporated with or connected
to the tap. That part of the lead pipe which is contained within the said chamber

page_text: is burnished or cleaned on the outside before introduction and when introduced is
passed over a ferrule or tube, either screwed or otherwise attached to the chamber,
or made in one piece therewith, and extending along the middle thereof. Between
the outside of the pipe and the inside of the chamber is a space, which, when the
pipe has been slipped over the ferrule, is filled with solder which is charged in,
either at the mouth of the chamber, or through an aperture provided in the wall of
the chamber, or is otherwise conveniently introduced.
A convenient shape for the chamber is approximately egg-shape, but it may be
globular or of other suitable shape. In its application to other water-fittings than
taps, the invention is carried out in substantially the same manner as for taps.
As adapted for horizontally arranged pipes, the solder is charged into the
chamber through an aperture in the wall aforesaid, and the chamber mouth fits the
pipe sufficiently closely to prevent escape thereat of the solder.
Referring to the accompanying drawings, Fig. 1 represents a tap a connected to
a horizontally disposed lead pipe 6 in accordance with one arrangement comprised
in this invention.
The pipe b is inserted in a chamber c of brass, gun-metal or other suitable metal,
either incorporated with or connected to the tap. The chamber c is tinned
internally for adherence of solder. Extending along the middle of the chamber c
is a ferrule or tube d, also of brass gun-metal or other suitable metal.
C
This ferrule d may either be screwed to the chamber c, or it may be otherwise
secured thereto, or it may be made in one piece therewith. The pipe 6 fits over
the ferrule d, as shown. Prior to inserting the pipe b in the chamber c, that part
of the pipe which is to be contained in the chamber is burnished externally. After
insertion of the pipe 6 in the chamber the latter is heated by the application of a
plumbers' blow-pipe, or soldering lamp, or by a gas-jet or other flame, and a stick
of solder is held at the aperture e provided in the wall of the chamber. The solder
as it fuses drops into the chamber c and fills the space f between the exterior of
the pipe 6 and the interior of the chamber, the mouth of which fits the pipe b
sufficiently closely to prevent escape of the solder. In cases where the mouth does
not fit sufficiently closely on the pipe b, the aperture is stopped by putty or other
suitable substance.
When desirable, the chamber c can be heated by the means aforesaid both before
and after insertion of the pipe b.
At Fig. 2 is illustrated the application of this invention to connecting a cistern
union a to a lead pipe b which latter is vertically situated. In such cases, that is
to say, when the pipe is vertical or sufficiently inclined, the solder is charged into
the chamber c at the mouth thereof which is sufficiently large for the purpose. As
in other cases, the ferrule d may be either screwed in place, as shown, or otherwise
fixed, or it may be made in one piece with the chamber c.
The employment of the ferrule d is not absolutely necessary in all cases, as,
instead thercof, a mandril or core of iron or other suitable material may be inserted
in the chamber c and the solder charged around it. After completion of the
connection, the mandril or core is withdrawn.
By connecting water taps and other water-fittings in accordance with this
invention, secure and watertight joints are obtained with less solder than heretofore
generally used. Economy in time and labour is effected and the joints have a
neater appearance.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. An improved method of connecting lead pipes to water taps and other water-
fittings; consisting of a chamber such as c, of brass or other suitable metal
internally tinned, connected to or incorporated with the tap or other fitting, and a
ferrule such as d extending along the middle of the said chamber over which
ferrule the pipe for connection is passed; solder being charged into the space

page_text: between the pipe and the interior of the chamber; either through an aperture
provided in the wall thereof or through the mouth thereof, substantially as
hereinabove described with reference to the accompanying sheet of drawings.
2. The modified method of making the connection, that is to say, without the
employment of a ferrule and by the use of a mandril or core of iron or other
suitable material temporarily inserted in the chamber c and withdrawn after the
solder is charged around such mandril or core.
