PROVISIONAL SPECIFICATION.
Improved Means for Coupling Lead Pipes to Lead or other Metal
Pipes, or to Taps.
We JOHN BRIERLEY, Bleacher, Dyer and Finisher, of Spring Clough, and
SAMURL MELLING Mechanic, of 4 Nipper Laue, both of Whitefield in the County of
Lancaster, do hereby declare the nature of this invontion to bo as follows:—
The object of this invention is to facilitate the connection of lead pipes together,
or of lead pipes with other metal pipes or taps, and to dispense with the necessity for
plumbers joints, solder, cement or india rubber or other packing rings.
For connecting two lead pipes together our apparatus consists mainly of a short
metal coupling tube, the bore of which is equal to that of the pipes to be coupled.
The ends of the said tube are made taper so that when inserted in the lend pipes
the ends of the latter are enlarged or made conical.
Over each of these onlarged or conical ends we bring a metal ring (preferably
coned internally) which has been placed on the pipe before the coupling tubo was
inserted; this metal ring is made with a collar, against which we bring a flange
placed ready upon the lead pipe and behind the ring.
The two adjacent ends of the pipes to be connected having been treated as above
described, the aforesaid flanges are drawn, towards each other either by screwed nuts
cast or fixed thereto and made to screw upon collars cast or fixed to the coupling
tube, or by bolts and nuts or other equivalent means.
The rings are thus formed on the enlarged or conical parts of the ends of the
lead pipes, which are therefore tightened upon the ends of the coupling tube above
described, and by these means we form a perfect and durable joint through which it is
impossible for anything to pass.

For coupling a lead pipe to a tap, or to a pipe of metal other than lead, such
tap or pipe is screwed or connected by an ordinary screw coupling to one end of
the coupling tube, the other end of which is formed as above described to connect it
to the lead pipe.
The coupling tube can have a branch or branches cast to it if desired, and thus
only one joint need be made for several branches. A tap may be also inserted in the
said tube.
The branches may be screwed for coupling a pipe (of other metal than lead) or a
tap thereto, or when lead pipes are to be connected thereto the ends of the said
branches are formed like the ends of the coupling tube as first above described.

Improved Means for Coupling Lead Pipes to Lead or other Metal
Pipes, or to Taps.
We JOHN BRIERLEY, Bleacher Dyer and Finisher, of Spring Clongh, and SAMUEL
MELLING, Mechanio, of 4 Nipper Lane, both of Whitefield, in the County of Lancaster,
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 :-
The object of this invention is to facilitate the connection of lead pipes together, or
of lead pipes with other metal pipes or taps, and to dispense with the necessity for
plumbers joints, solder, cement or india rubber or other packing ring.
For connecting two lead. pipes together our apparatus consists mainly of a short
metal coupling tube, the bore of which is equal to that of the pipos to be coupled.
The ends of the said tube are made tapered to a feather edge so that when inserted
in the lead pipes the ends of the latter are enlarged or made conical.
Over each of these enlarged or conical erids we bring a metal ring (preferably
coned internally) which has been placed on the pipe before the coupling tube was
inserted; this metal ring is made with a collar against which we bring a flange placed
ready upon the lead pipe and behind the ring.
The two adjacent ends of the pipes to be connected having been treated as
above described, the aforesaid flanges are drawn towards each other either by
screwed nuts cast or fixed thereto and made to screw upon collars cast or fixed to the
coupling tubo, or by bolts and nuts or other equivalent means.
The rings are thus forced on the enlarged or conical parts of the ends of the lead
pipes, which are therefore tightened upon the ends of the coupling tube above
described the ends of the lead pipes abutting against the collar on the coupling tube
and by these means we form a perfect and durable joint through which it is impossible
for anything to pass.
For coupling a lead pipe to a tap or to a pipe of metal other than lead, such tap
or pipe is screwed or connected by an ordinary screw coupling to one end of the
coupling tube the other end of which is formed as above described to connect it to
the lead pipe.
The coupling tube can have a' branch or branches cast to it if desired' and thus only
- one joint need be made for several branches. A tap may be also inserted in the said
tube.
The branches may be screwed for coupling a pipe (of other metal than lead) or a
tap thereto, or when lead pipes are to be connected thereto the ends of the said
branches are forined like the ends of the coupling tube as first above described.
In order that our invention may be more clearly understood we have annexed
hereto a sheet of drawings illustrative thereof.
Fig. 1 on the annexed drawings shews in section our means for connecting or
coupling two lead pipes together. a a' are the two lead pipes; bb is the coupling tube
made conical at each end to open out the ands of the pipes a a¹ as shewn; care the
metal rings with collars c' drawn together as above described by flanges & upon nuts d'
shewn as screwed' upon the central flange or collar 6 on' the tube b br.

Fig. 2 shews in section our means for connecting a lead pipe a to a pipe of metal
other than lead or to part of a tap as seen at a³, and also shewing that the flange d may
be drawn to the collar on the tube bb by means of bolts d. The part of the tap
or pipe a³ is connected by the coupling e to the end 6' of the tube 66 which in this
oase is screwed as seen. In this case the conical ring c and the flange d may be made
in one piece as shown.
Fig. 3 shows how the coupling tube may be provided with branches.

page_text: The drawing shews two conical ends to a bent coupling tube bb and two
branches 63 b which are in the form of screwed sockets, but it will be evident that
either or both branches may be in the form shewn at b and b¹.
It will be evident without illustration that a tap may be inserted between 6 and bl
if the coupling tube is long enough to admit of such a construction.
It will also be evident that our improved apparatus can be applied to the coupling
of pipes of other expandible material as well as lead pipes.
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. The combination of a coupling tube (with or without branches) having a conical
end made with a feather edgo for opening out the lead or other expandible pipe, and
a suitable screwed collar or a flange or its equivalent with a corresponding loose
conical ring, a screwed flange, bolts, or other equivalent connection for drawing the
conical ring up towards the collar or flange on the coupling tube and over tho conical
end of the coupling tube, so as to canse the end of the lead pipe to abut against
the collar, and means for connecting the other end of the coupling to the pipe or tap
to which the said expandible pipe is to be coupled as horeinbefore described and
illustrated by the drawings annexed.
2. For coupling two lead pipes together, a coupling tube having two conical
feather edged ends and an intermediate screwed collar or collars in combination with
two flanged conical loose rings, and two internally screwed and flanged rings for
fitting on the collar and drawing the said loose rings and the ends of the lead pipes
up towards the shoulders of the said screwed collar or collars as hereinbefore described
and illustrated by the drawings annexed.
