page_text: I, ARTHUR CLARKE, of the Firm of Richard Clarke and Co., of Milton Works,
Heckmondwike, in the County of York, Manufacturers, do hereby declare the
nature of this invention to be as follows:
This invention refers to an improved construction and arrangement of joint par-
ticularly intended for the jointing together of tin lined lead piping in which a
section of non conducting material or substance is placed intermediate of the tin
lining and the lead or like soft metal outer pipe or casing.
In carrying out my invention I cast in, or otherwise suitably form of tin or like
metal employed to form the lining of the pipe a tee, cross, or equivalent shaped
pipe or jointing piece having one, two or more ways therethrough to suit the
number and position of pipes to be jointed together. The outside of the said joint-
ing piece I surround with asbestos or other non conductor which is built up to
the requisite thickness or section to coincide with the section in the lined pipes and
covers only the middle portion or junction of said piece leaving short lengths of the
tin pipe projecting therefrom, the faces or ends of the non conducting section being
cut clean and approximately true. After applying the non conductor, the jointing
piece is placed in a mould and a lead or like soft metal casing or pipe moulded over
the non conductor, so that when completed the central portion of the jointing
piece corresponds to the tin lined non conducting pipe. In making a joint the
ends of the pipes to be jointed together are slightly enlarged by a suitable tool to
admit the projecting ends of the jointing piece which are driven or forced tightly
into the lining of the pipes (or the pipes are driven or forced on to same) until
the faces or ends of the lead and non conductor, sections abut against the ends of
the pipes, after which the joint is made perfectly water tight in the usual way.
The asbestos or non conductor may be cut out in one piece to surround the joint-
ing piece where the junction occurs, or it may be wrapped or otherwise applied
as found most suitable.
By the employment of a jointing piece such as before described a tight firm joint
can be easily and quickly made, nothing being required beyond the cutting out
of a portion of the pipe where another pipe has to be joined thereto, and the intro-
duction of the said jointing piece, the whole being then sealed in the ordinary
manner.

I, ARTHUR CLARKE, of the Firm of Richard Clarke and Co., of Milton Works,
Heckmondwike, in the County of York, Manufacturers, 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 refers to an improved construction and arrangement of joint
particularly intended for the jointing together of tin lined lead piping in which a
section of non conducting material or substance is placed or formed intermediate
of the tin lining and the lead or like soft metal outer pipe or casing.
In carrying out my invention I cast in, or otherwise suitably form of tin or like
metal employed to form the lining-of the pipe, a tee, cross, or equivalent shaped
pipe or jointing piece having one, two or more ways therethrough to suit the
number and position of pipes to be jointed together. The outside of the said joint-
ing piece I surround with asbestos or other non-conductor which is built up to
the requisite thickness or section to the requisite thickness or section to coincide
with the section in the lined pipe and covers only the middle portion or junction
of said piece, leaving short lengths of the tin pipe projecting therefrom, the faces
or ends of the non-conducting section being cut clean and approximately true.
After applying the non-conductor, the jointing piece is placed in a mould and a
lead or like soft metal casing or pipe moulded or cast over the non-conductor, so
that when completed the central or mid portion of the jointing pieces corresponds
to the tin lined non-conducting pipe. In making a joint, the ends, of the pipes to
be jointed together are slightly enlarged by any suitable tool to admit the projecting
ends of the jointing piece which are forced tightly into the lining of the pipe until
the faces or ends of the lead and non-conductor sections abut against the ends
of the pipes, after which the joint is made perfectly watertight in the usual way.
In order that my invention may be fully understood reference is hereafter had to
the annexed drawings forming a part of this specification, in which:-
--
Fig. 1 is sectional elevation of a tee piece or joint constructed according to my
invention;
Fig. 2 shews the method of applying my improved jointing piece for making a
branch joint; and
Fig. 3 is part sectional elevation of a cross or four way piece for jointing two
branch pipes;
The improved jointing piece comprises a central tee, cross, or other
shaped tube A having two, three or
suit
more thoroughfares to
the number and position of the pipes to be jointed together; a non-conducting
section B applied around the middle portion or junction of said shaped tube so as
to leave the ends projecting, and an outer section C composed of lead or other suit-
able metal which is cast or moulded around the non conducting section B. The
tube or shaped inner portion A is composed of block tin or other non-corrosive
metal employed as a lining for water or like pipes to which it is intended to apply
same for jointing the pipes together, and is of corresponding diameter to the
lining D of said pipes. The non-conducting section B may be composed of asbestos
or other suitable non-conductor and is built up or laid around the tube A to the
required thickness to coincide with the non-conducting section E of the water
pipes, the middle portion or junction of the shaped piece A alone being covered so
that the ends of piece A shall project a short distance beyond each face of the
non-conductor and metal shell or casing C, these faces being made true or approxi-
mately true. After applying the non-conductor, the jointing piece is placed in a
mould and the lead or like soft metal shell or pipe C cast or moulded around same,
whole, when completed, corresponding to the lined non-conducting pipes.

page_text: In Fig. 2 I have shewn the method of applying my improved jointing piece for
jointing a branch pipe F to the main pipe F. The pipe F is sawn or otherwise
severed in two where the branch pipe is to be joined to same. The said severed
ends of pipe F and the end of branch pipe F1 are then expanded to receive the
projecting ends of the shaped tube A of the jointing piece after which the faces of
the pipe ends and the jointing piece are brought close together and the joint
soldered or wiped in the usual way to complete and make it watertight.
Although I have shewn only two forms of jointing pieces, it will be quite
obvious that the jointing piece may take any form best suited to the position and
number of pipes to be jointed together, the same construction and method of appli-
cation being followed in all cases whatever the shape of the central portion A may
be. A single way jointing piece for jointing the ends of two pipes together may be
made as above described where required.
By the employment of a jointing piece such as before described, a tight firm joint
can be easily and quickly made, nothing being required beyond the cutting out
of a portion of the pipe where another pipe has to be joined thereto and the intro-
duction of the said jointing piece, the whole being then wiped in the usual manner.
The jointing piece gives a continued non-corrosive lining and prevents contact
between the water and the lead.
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 what
I claim is:
:-
The improved jointing piece comprising a non-corrosive hollow metal lining or
piece having a non-conducting section surrounding the middle portion of same or
the junction of its members or extensions, and a metal shell or casing cast
or moulded around the said non-conducting section, all arranged and constructed in
the manner and for the purposes substantially as herein shewn and described.
Dated this 7th day of January 1898.
