An Improvement or Improvements in Joining or Connecting.
Metallic Pipes.
I RICHARD HOBBS TAUNTON of Heneage Street Birmingham in the County of
Warwick Tube Manufacturer do hereby declare the nature of this Invention to be as
follows:-
My invention has reference principally to the joining or connecting of iron pipes
such as are used for the conveying of water under pressure but is also applicable to
the joining of iron and other metallic pipes for various purposes My said invention
has for its object to effect a secure and rapid joining or connecting and disconnecting
of metallic pipes and also to allow of a slight play at the junction of the pipes without
diminishing the tightness or soundness of the junction.
I make collars on the ends of the pipes to be joined. Between these collars I place
a ring or washer of vulcanized india rubber or other elastic material and I press the
said collars together so as to form with the said elastic washer a tight joint by means
of two strong cast iron or other rings or loose flanges situated respectively on the two
pipes shoulders on the inner faces of the said rings engaging on the collars. on the
ends of the pipes. These rings or loose flanges have sungs at two opposite .points.
The said snugs having holes in them through which screw bolts are passed screw nuts
being screwed onto the ends of the screw bolts the said rings or loose flanges and with
them the collars of the pipes are drawn forcibly together and the junction or connection
of the pipes effectel.
Although two snugs at opposite points on the rings are under ordinary circumstances
sufficient for pipes of moderate diameter yet three or more snugs for receiving screw
bolts and screw nuts may be employed where by reason of the size of the pipes or
the pressure to which they are to be exposed it may appear desirable..
+
The collars on the ends of the pipes to be joined may either be made in one piece
with the pipes or they may be made separately and attached to the ends of the pipes
by brazing screwing or otherwise.

Metallic Pipes.
I RICHARD HOBBS TAUNTON of Heneage Street Birmingham in the County of
Warwick Tube Manufacturer do hereby declare the nature of my Invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention has reference principally to the joining or connecting of iron pipes
such as are used for the conveying of water under pressure but is also applicable to
the joining of iron and other metallic pipes for various purposes. My said invention
has for its object to effect a secure and rapid joining or connecting and disconnecting
of metallic pipes and also to allow of a slight play at the junction of the pipes without
diminishing the tightness or soundness of the junction.
I make collars on the ends of the pipes to be joined. Between these collars I place
a ring or washer of vulcanised india rubber or other elastic material and I press the
said collars together so as to form with the said elastic washer a tight joint by means
of two strong cast iron or other rings or loose flanges situated respectively on the two
pipes, shoulders on the inner faces of the said rings engaging on the collars on the
ends of the pipes. These rings or loose flanges liave snugs at two opposite points,
the said snugs having holes in them through which screw bolts are passed. Screw
nuts being screwed onto the ends of the screw bolts, the said rings or loose flanges
and with them the collars of the pipes are drawn forcibly together and the junction or
connection of the pipes effected.
Figure 1 of the accompanying Drawing represents partly in longitudinal section
and partly in side elevation and Figure 2 in end elevation iny method of joining or
connecting the ends of iron or other inetallic pipes.
The same letters of reference indicate the same parts in both Figures.
a, bare the ends of the two pipes to be joined together the said ends being provided
with collars marked respectively a² and 62. The collars a², 62 on the ends of the pipes
to be joined may either be made in one piece with the pipes or they may be made
separately and attached to the ends of the pipes by brazing screwing or otherwise; cis
the ring or washer of vulcanized india rubber or other elastic material placed between
the two collars a², 2; d, e are the two rings or loose flanges situated respectively on
the ends of the pipes a, b for the purpose of pressing the said collars a², together
and forming with the elastic washer ca tight joint between the ends of the two pipes.
The inner faces of the two rings or loose flanges d, e are provided with shoulders
at d², e² for engaging with the collars a², 62 as seen in Figure 1; de³ are perforated
snugs at opposite points on the rings or loose flanges d, e through which screw bolts, f
are passed and secured by the nuts for binding together the two rings or loose
flanges de.

page_text: In joining or connecting the ends of the pipes a, b together the collars a², on
their ends are brought together with the elastic washer e between them and the two
rings or loose flanges d, e are engaged by their shoulders d with the said collars.
The screw bolts are next passed through the snugs d³, of the rings or loose
flanges d, e and the screw nuts y, y are screwed on the ends of the screw bolts. The
said rings or loose flanges d, e and with them the collars a², 2 on the pipes a, b are
thereby forcibly drawn together compressing between them the elastic washer c the
collars a preventing the lateral spreading of the said elastic washer. A very secure
junction is thus made.” In consequence of the elasticity of the washer ca slight play
at the junction of the pipes may occur without interfering with the tightness of the
junction.
Although two snugs at opposite points on the rings or loose flanges are under
ordinary circumstances sufficient for pipes of moderate diameter yet three or more
snugs for receiving screw bolts and screw nuts may be employed where by reason of
the size of the pipes or the pressure to which they are to be exposed it may appear
desirable.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that what. I claim is :-
Joining or connecting metallic pipes by making or fixing on the ends of the pipes
to be joined the collars a², between which an elastic ring or washer is pressed by
means of rings or loose flanges d, e on the said pipes bound together by screws and
screw nuts substantially as herein before described and illustrated in the accompanying
drawing.
