Newcastle-upon-Tyne Electrical Engineer GEORGE MACKIE 151 Pilgrim Street

Shieldfield Newcastle-upon-Tyne aforesaid Electrical Engineer and GEORGE BONSTEAD
HUGHES of 171 Monday Street Arthur's Hill Newcastle-upon-Tyne aforesaid
Carver and Gilder do hereby declare the nature of this invention to be as
follows:-
In joining pipes we intend to dispense with both solder and screwing the ends of
the pipes, to accomplish which we use a male and female coupling outside the pipe to
press it on to a double coned tube inside the pipe maintaining thereby the full area
of the pipe and a clear way without any resistance shoulders; in the case of joining
lead or soft pipes of any kind to iron or hard pipes we use one half of the coned tube
before mentioned with a recess in it to receive the iron pipe, we place it inside the
lead pipe and on the iron pipe we place a piece of lead or soft inaterial tube, the
male and female coupling then are screwed together forcing the lead pipe on to
the half or single cone, and the short piece of lead tube is forced by a female cone
turned in the coupling on to the iron pipe and against the end of the single cone.
joining taps, cocks, we cast a cone on the end of the article to be joined and use the
female half of the coupling to press the soft pipe down on to it.

COMPLETE SPECIFICATION.
Improvements in the Method of Coupling or Joining Water, Gas,
Steam, and every other kind of Pipe.
We, ROBERT CURRY, of 47 Breamish Street, Electrical Engineer, GEORGE MACKIE,
of 151 Pilgrim Street, Electrical Engineer, THOMAS SOUTER of 91 Henry Street,
Shieldfield, Electrical Engineer, and GEORGE BONSTEAD HUGHES, of 171 Monday
Street, Arthur's Hill, Carver and Gilder, all of the City and County of Newcastle-
upon-Tyne, 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 the coupling of pipes without the use of solder or screwing
the ends of the pipe by the use of a novel tubular double coned washer, and a union
connection, a modification of which is suitable for coupling pipes to taps specially
arranged for such connection.
To enable our invention to be properly understood, we will proceed to describe the
same with aid of the accompanying drawings.

Figure 2. sectional view of same.
Figure 3. longitudinal view of coupled iron and lead pipes.
Figure 4. sectional view of same.

page_text: Figure 7. sectional view of coupling pipe to tap.
A lengths of lead pipe, B, C union connection loose on pipe; D tubular doubled
coned washer, the internal diameter of which is the same as that of the pipes to be
coupled. The ends of the pipes where the coupling is to take place are bulged out
as at E, to make the interior to correspond to the outside diameter of the double
cone D, the union connection is then brought together, and screwed up in the usual
way, the pipes being then joined as at Figures 1 and 2. The inside bearings of
connections B, C, are tapered as at F, corresponding to the outside of the parts E of
the pipes, so that by screwing the connections B, C, together the tapered parts F will
have a tendency to compress the bulged ends of the pipes tight upon the outside of
the double cone D producing a hermitically tight joint.
Figures 3 and 4 show how the invention is applied to joining a lead and a pipe, of
other metal or material than lead. A being the lead pipe and G an iron or other
pipe.
In this arrangement a lead double coned washer H is placed upon the iron pipe,
and a metal socket connection J externally screw thread, having a coned front K to
pass into the bulged mouth E of the lead pipe A, and a tapered mouth L for one end
of lead cone H to enter with end of pipe, then the connections C-in this case the two
connections are similar in construction-are brought together and screwed on to the
metal socket J, the tapered insides F of the connections C, will on these being screwed
tight, compress the lead cone on to the iron pipe G, and the outside of the E part of
lead pipe on to and around the cone part K thereby affecting a hermitically tight
joint.
Figures 5 and 6 show the manner the invention is preferred to be used in joining
stiff metal or other pipes than lead. G are iron pipes. M lead double cone preferably
with inside central flange N, the connections B, C, being same as described at Figures 1
and 2 the inner bearing F being rather more tapered.
Figure 7 shows the invention as applied to connecting pipes to taps and which for
the purpose of illustration shows a connection made to a lead pipe. In this plan the
tap is made with cones O and threads P, the cone O is inserted into the mouth E of
the lead pipe A, and the connection C, screwed on to the thread P, thereby joining
the pipe to tap as has been described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. The manner of coupling lead pipes or other pipes of soft material consisting of
the connections B C, and double coned washer D, as hereinbefore described and
illustrated by the accompanying drawings at Figures 1 and 2.
2. The manner of coupling a lead pipe to another pipe other than lead, consisting
of the connections C, the lead double coned washer H and metal socket J, as
hereinbefore described and illustrated by the accompanying drawings at Figures 4
and 5.
3. The manner of coupling pipes other than lead consisting of the double_coned-
washer M, preferably formed with an inner central flange N and connections B C, as
herein before described and illustrated by the accompanying drawings at Figures 5
and 6.
4. The manner of coupling pipes to taps, consisting of forming the tap with cones O
and threads P, and connections C, as hereinbefore described and illustrated by the
accompanying drawings at Figure 7.
