PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Joining and
Coupling Pipes and Tubes.
We, HENRY GIBBON of 10 Atherton Street, Prescot, in the County of
Lancaster, Millwright and WILLIAM TYRER of 13 Vicarage Place, Prescot,
aforesaid, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a method of and apparatus for joining and
coupling pipes and tubes without soldering the same.
The apparatus comprises a tubular union which externally is slightly tapered
from about the middle towards each end, and flanges, or their equivalent, for
coupling or joining the ends of the pipes or tubes together.
To join the ends of two pipes, the flange is placed on the end of one of the pipes :
the union is pressed or forced onto the pipe so as to expand its end and form a
flaring mouth therefor. The end of the other pipe is subjected to the same opera-
tions. The two flanges are pulled towards each other by means of bolts and nuts
and as the flaring ends of the pipes form stops for the flanges, whereby the latter
cannot be pulled off, the pipes are drawn firmly against the conical or sloping ends
of the union and a tight joint obtained.
We have described one way in which our invention may be carried into effect,
but it will be understood that once given the general idea certain alterations may
be made without departing from the principle of our invention; for example,
instead of flanges being used, a kind of gland may be employed, or the flanges may
be made in such a way as to screw one onto the other and the joint formed by
screwing these two parts together. By this means a very tight and secure joint
can be produced.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Joining and
Coupling Pipes and Tubes.
We, HENRY GIBBON of 10 Atherton Street, Prescot in the County of
Lancaster, Millwright and WILLIAM TYRER of 13 Vicarage Place, Prescot,
aforesaid, Gentleman, 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 has for its object a method of and apparatus for joining and
coupling pipes and tubes without soldering the same.
It is best understood from the following description, reference being had to the
accompanying drawings, in which :-
Figures 1 and 2 show arrangements for connecting up two ends of pipes ;
Figure 3, a separate view of double cone;
Figures 4, 5 and 6 show various arrangements for connecting a faucet or screw
joint with a pipe ;
Figure 7, a separate view of a single cone; and
Figure 8, a connection between a main pipe and a branch pipe.
The invention consists practically in enlarging the end of the pipe so as to form

page_text: a conical trumpet mouth, then placing a wedge-shaped mouth piece or tubular union
into this mouth, placing also (in some cases) a washer with a conical hole over the
cone pipe and drawing the washer and cone towards each other by means of a
screw or screws.
Referring first to Figures 1, 2 and 3—
A, B, are the two ends of pipes to be joined up: C, a double cone or tubular
union fitting one end into each pipe: D and D' are flanges or collars having holes
fitting the said pipes: H, a bolt: and J, a nut for drawing the two parts D and D'
tightly together.
In Figures 4, 5, 6, & 7 similar letters relate to similar parts. In Figure 4, a
single cone G is used instead of a double cone; the nut I draws up the collar D
precisely as in Figures 1 and 2. In Figure 5, the part G is screwed into the faucet
instead of resting against it, and is formed in one with the part D. In Figure 6,
the single cone G is made separate from the faucet I, but it is obvious it could be
formed in one therewith; the nut J is also of a different shape.
In Figure 8, the part C has a projection L thereon with a passage K there-
through; the remaining parts are similar to those already described.
It is obvious that the part C or G can be formed in one with one of the pipes in
all instances, instead of being an independent pipe. .
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. In a junction for pipes or other conduits, the combination of an enlarged
conical end of the pipe, a cone fitting into the said conical end having watertight
connection with the conduit to be joined to the said pipe and having substantially
the same bore as the pipe, a collar with a conical hole fitting the outside of the
conical month of the said pipe, and a tightening up device whereby the collar can
be pressed towards the coue in a direction parallel with the axis of the conduit and
thus the enlarged mouth of the pipe tightly pressed against the cone.
2. The combination of the pipe A having an enlarged conical end with a piece
fitting into the said conical end, and connected in a watertight manner with the
pipes to be connected with that pipe, a collar with conical hole entirely surrounding
the enlarged part of the pipe and means for drawing the collar tightly up the incline
of the pipe.
3. The combination of the two pipe ends A and B, the double conical mass C
fitting those two ends, collars D and D' fitting the outside of the enlarged conical
ends of the pipes A and B, and a screw and nut device H H adapted to force the
parts D'and D' towards each other.
4. The combination of a pipe A having an enlarged conical end, a projecting
conical end in watertight connection with the pipe or conduit to be connected with
the pipe A, entering the enlarged part of pipe A, a non-extensible collar D
surrounding the pipe A and a device for forcing the cone into the conical mouth of
pipe A
