We, FERNAND HENRY, and LEON LECELLIER, both of Villedieu, in the Republic
of France, Engineers, do hereby declare the nature of this invention to be as
follows
--
Our invention relates to couplings for pipes, and has for its object improvements in
such couplings by which they can be instantly connected or disconnected without the
use of a key or instrument of any kind, whilst the coupling can turn upon its axis
when connected without affecting the tightness of the joint.
The improved coupling consists of a hollow nut which screws upon the corresponding
screwed end of one part of the coupling and holds against the end of the latter a ring
or washer of india rubber. At the outer end of the nut are formed two notches. The
end of the other part of the coupling, which passes freely through the nut and enters
the first part of the coupling, is reduced in diameter for a sufficient part of its length
near the end, and upon the recess formed by this reduced part is fitted freely a
cylindrical ring of shorter length so that it can move for a short distance end ways.
Upon the outer end of this ring are formed two projections or lugs which can enter
the two notches already described at the end of the nut.
In order to connect the coupling, it is only necessary to push the second part of the
latter through the nut until it enters the first part, taking care that the lugs are not
opposite to the notches, and the inner edge of the india rubber ring or washer will then
enter and fit round the end of the recess upon the inner part of the coupling between
it and the end of the moveable cylinder, so as to form a tight joint.
To disconnect the coupling, the moveable cylinder is turned round by hand until the
lugs upon it coincide with the notches upon the end of the nut, and it is then forced
inward so that it presses the india rubber ring outward until it clears the
recess, and
the inner part of the coupling together with the moveable ring round it can then be
readily withdrawn through the nut.
Where it is desired that the joint of the coupling should resist pressure from
without as well as from within, the india rubber ring or washer is made with a more
or less cylindrical flange embracing the inner end of the coupling upon each side or

page_text: the part of the ring which is held by the nut against the end of the outer part of the
coupling as already described, the inner part of such flange making a tight joint
against pressure from within and the outer part against pressure from without. The
inner part of the coupling is in this form prevented from leaving the outer part by a
sufficient number of loose catches or detents fitting in corresponding holes through the
side of the outer part of the nut, their ends entering the inner end of the recess
already described round the inner part of the coupling above the loose cylinder.
The inner sides of these loose catches are made inclined so that when the loose
cylinder is pressed inward as already described it forces the catches outward and the
inner part of the coupling can then be withdrawn without difficulty.
The catches are pressed inward by a ring of india rubber fitting round them in a
recess round the nut, and they are provided with external flanges or projections which
prevent them from being forced too far in when the coupling is disconnected.
Where two pipes having at their ends the outer parts of the coupling described, are
to be connected together, a short separate pipe may be used each end of which enters
one of such pipes, the junction being effected in the manner described.
The end of the inner pipe is made taper or conical so as more readily to enter the
india rubber ring.

WC, FERNAND HENRY, and LEON LECELLIER, both of Villedieu, in the Republic
of France, Engineers, 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, and accompanying drawing, (that is to say) :-
Our invention relates to couplings for pipes, and has for its object improvements in
such couplings by which they can be instantly connected or disconnected without the
use of a key or instrument of any kind, whilst the coupling can turn upon its axis
when connected without affecting the tightness of the joint.
In the accompanying drawing, which is in illustration of our invention, figure 1 is
a vertical section through the coupling, figure 2 an elevation of the same; Figure 3
a vertical section through a coupling to resist pressure from without as well as from
within, figure 4 represents the india rubber washer or flanged ring, figure 5 the nut
by which the coupling is joined, and figure shows front and side views of the loose
catch used.
The form of the improved coupling shewn in figures 1 and 2 consists of a hollow
nut a which screws upon the corresponding screwed end of one part of the coupling b
and holds against the end of the latter a ring or washer of india rubber c. At the
outer end of the nut a are formed two notches d.
The end of the other part of the couplinge which passes freely through the nut and
enters the first part of the coupling, is reduced in diameter for a sufficient part of its
length near the end, and upon the recess formed by this reduced part is fitted freely
a cylindrical ring f of shorter length so that it can move for a short distance
end ways.
Upon the outer end of this ring f are formed two projections or lugs g which can
enter the two notches already described at the end of the nut.
In order to connect the coupling, it is only necessary to push the part e of the latter
through the nut until it enters the other part b, taking care that the lugs g are not
opposite to the notches d, and the inner edge of the india rubber ring or washer c will
then enter and fit at round the end of the recess upon the inner part of the coupling e
between it and the end of the moveable cylinder f, so as to form a tight joint.
To disconnect the coupling, the moveable cylinder is turned round by hand until
the lugs upon it coincide with the notches d upon the end of the nut, and it is then
forced inward so that it presses the india rubber ring c outward into the space k
between the parts b and e until it clears the recess, and the inner part of the coupling e
together with the moveable ring round it can then be readily withdrawn through the
nut, the india rubber ring c meeting nothing to detain it.
When it is desired that the joint of the coupling should resist pressure from without
as well as from within (as illustrated in figures 3, 4, 5, and 6) an india rubber ring or
washer i is used with a more or less cylindrical flange embracing the inner end of the

page_text: coupling upon each side of the part of the ring which is held by the nut m against
the end of the outer part of the coupling as already described, the inner or upper part
of such flange upon the ring i making a tight joint against pressure from within and
the outer or lower part against pressure from without.
The inner part p of the coupling is in this form prevented from leaving the outer
part by a sufficient number of loose catches or detents 7 fitting in corresponding holes n
through the side of the outer part of the nut m, their ends entering the inner end of
the recess already described round the inner part of the coupling above the loose
cylinder.
The inner sides of these loose catches are made inclined so that when the loose
cylinder is pressed inward or upward as already described it forces the catches
outward and the inner part p of the coupling can then be withdrawn without difficulty.
The catches are pressed inward by a ring of india rubber o fitting round them in a
recess round the nut m, and they are provided with external flanges or projections as
shown which prevent them from being forced too far in when the coupling is
disconnected.·
Where two pipes having at their ends the outer parts of the coupling described, are
to be connected together, a short separate pipe may be used each end of which enters
one of such pipes, the junction being effected in the manner described.
The end of the inner pipe is made taper. or cónical so as more readily to enter the
india rubber ring.
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 is :-
1. The combination of the nut a, and the pipe
stantially as described and shewn in figures 1 and 2.
with the ring or washer c, sub-
2. The combination of the moveable cylinder with the pipe e and the ring or
washer e substantially as described and shewn in figures 1 and 2.
3. The combination of the catch or catches I, with the nut m, and the clastic ring o,
substantially as described and shewn in figures 3, 4, 5, and 6.
4. The combination of the flanged ring or washer with the nut m and the pipe,
substantially as described and shewn in figures 3 and 4.
