Improvements in Pipe Couplings.
We, WILLIAM JOHN HENNING (Chief Engineer, Water Works), of 407,
Caroline Street, and LAWRENCE LEY HIGGS, (Assistant Engineer), of 614, Caroline
Street, Key West, in the County of Monroe, and State of Florida, United States
of America, 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 a pipe coupling adapted to join the ends of pipes,
especially when the pipe sections are mounted rigidly and cannot be moved
toward or from each other, the invention being adapted to all sizes of pipes and
being capable of joining to each other, pipes of different diameters.
This specification is the disclosure of one form of the invention, while the
claims define the actual scope thereof.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in both views.
Figure 1 is a longitudinal section of the invention; and
Figure 2 is a view showing one of the pipe members in section on the line
2-2 in Figure 1.
The invention is illustrated as applied to pipe sections 3 and 4 of different
diameters. The coupling comprises a sleeve 5 loosely embracing the pipe sec-
tion 4, and having at its inner end a shoulder 6 and a' flange 7. A sleeve 7" is
threaded on the pipe section 3, and has a flanged inner end 8, between which
and the shoulder 6 of the sleeve 5, a gasket 9 is arranged.
A collar 10 has an inwardly projecting flange 11 engaging the flange 8 of
the sleeve 7, the collar 10 projecting beyond the sleeve and being threaded
on the sleeve 5 so that by drawing up the collar 10, the sleeves 5 and 7ª may
be drawn together and the gasket 9 pressed securely to effect a hermetic con-
nection. For the purpose of mounting the sleeve hermetically on the pipe sec-
tion 4, a gland-like collar 12 is threaded on the outer end of the sleeve 5, and
formed with an annular chamber 14, in which a packing material 15 is arranged.
Now by screwing up the collar 12 on the sleeve 5, the packing ring 15 will
be compressed and forced tightly around the pipe section 4, to hermetically seal
the outer end of the sleeve 6.
By this arrangement, it is possible to hermetically couple the ends of pipes
without moving the pipes, and also pipes of any diamoter may be joined to pipes
of unlike diameter, this being effected by regulating the interior size of the
sleeves 5 and 7*.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim ie: -
1. The sleeve 5 and the sleeve 7ª, and the devices for connecting them for the

page_text: 2. The sleeve 5 having flange 7, and the sleeve 7" having flange 8, with the
devices for connecting the sleeves, for the purpose specified.
3. The internally threaded collar 10, with the flange 11, for the purpose
specified.
4. The sleeves 5 and 7ª, and the collar 10, for the purpose specified.
