PROVISIONAL SPECIFICATION.
Improvements in Joints for Tubes, Connecting Vessels with their
Covers, and other purposes.
We, WOLF DEFRIES, of 4 Danes' Inn, Strand, London, and VICTOR ISIDORE
FEENY, of 60 Queen Victoria Street, London E.C., Engineers, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to improvements in the construction of mechanical joints
for tubes, or for detachably connecting the neck of a vessel either with a cover or
with a tube, union or other fitting, and has for object to provide a simple means
for readily effecting the connection or disconnection of such joints. It consists in
adopting the forms of construction of the respective parts to be joined which are
hereinafter described.
In applying our invention to the closing of the mouth of a bottle or other
hollow vessel, we form on either the inner or the outer surface thereof, projections
of which the faces furthest removed from the mouth of the vessel are formed as
inclined planes.
Corresponding projections are formed on either the outer or inner surface
respectively as the case may be, of the cover or stopper of width sufficiently small
to pass between the projections on the mouth of the vessel, and at a depth such as
will cause the two sets of projections by abutting on each other to draw the flange
or end of the cover or stopper into close contact with the end of the mouth of the
vessel when the cover or stopper is slightly rotated.
This joint may be made tight by the use of an elastic washer or ring or equivalent
device.
Instead of forming projections on the outside of the cover or stopper, we may
provide it with a flange to slip over the projections on the mouth of the vessel
furnished with returns corresponding to the projections on the mouth of the vessel,
as in the arrangement previously described, the operation of closing being the same
in each case.
In cases where the vessel is to contain fluid at a substantial pressure, we prefer
to form the projections on the outside of the vessel, and to substitute for the ordinary
elastic washer, an elastic ring of L-section preferably thickened at the vertex and
fixed within the mouth of the vessel with its return angle parallel to the plane of
the cover.
A turned face on the cover comes into rough contact with this web of
the rubber ring, and the internal pressure forces it into a joint practically sound
against fluid at any pressure.
In applying our invention to the connection of tubes to each other, we may form
projections on the pipes in a manner corresponding to that described above,-the
one pipe taking the place of the vessel, and the other that of the cover, and the
joint made being consequently of the spigot and socket type.
Alternatively we may make our improved joint between the butt ends of the two
tubes which are brought into contact, by means of a union having projections at
each end arranged to engage in a similar manner to that described above with
corresponding projections on the tubes, and provided if necessary with suitable
elastic washers, or rings, or other ordinary means for making a sound joint.

page_text: We may make our improved joint of either glass metal or any other material
suitable for the particular purpose for which the joint is intended to be used.

Improvements in Joints for Tubes, Connecting Vessels with their
Covers, and other purposes.
We, WOLF DEFRIES, of 4 Danes' Inn, Strand London, and VICTOR ISIDORE
FEENY, of 60 Queen Victoria Street, London, E.C. 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 :-
Our invention relates to improvements in the construction of mechanical joints
for tubes, or for detachably connecting the neck of a vessel either with a cover or
with a tube, union or other fitting, and has for object to provide a simple means for
readily effecting the connection or disconnection of such joints. It consists in
adopting the forms of construction of the respective parts to be joined which are
hereinafter described.
In order that our invention may be more clearly understood reference is had to
the accompanying drawings upon which,
Figure 1 is an elevation of our improved joint as formed for closing the mouth of
a vessel.
Figure 2 being a section of the same.
Figure 3 is a longitudinal section of a coupling for pipes constructed according
to our invention, and
Figure 4 is a cross-section of the same.
In applying our invention to the closing of the mouth of a bottle or other hollow
vessel we adopt the method of construction shewn on Figures 1 and 2. On the
outer surface of and around the mouth A we form projections B, of which the
.surfaces furthest removed from the mouth of the vessel are formed as inclined planes,
and are also preferably undercut.
Corresponding projections C are formed on the inner surface of the cover or
stopper D, of a width capable of passing between the projections B on the mouth A
of the vessel, and at such a depth as will cause the set of projections C on the
stopper to abut against, and engage with the other set B when the cover or stopper D
is slightly rotated, whereby the flange or end of the cover or stopper will be drawn
into close contact with the end of the mouth A of the vessel, and held in the closed
position.
The above described joint may be made tight by the use of an elastic washer or
ring, or equivalent device.
We may otherwise form the projections B and C respectively on the inner surface
of the mouth A of the vessel, and on the outer surface of the cover or stopper D,
with the same result as in the arrangement already described; the operation of
closing being similarly effected in each case.
In cases where the vessel is to contain fluid at a substantial pressure, we may
form the projections on the outside of the mouth A of the vessel, and substitute
for the ordinary elastic washer, an elastic ring of L-section E preferably thickened
at the vertex, and fixed within the mouth A of the vessel, its upper surface being
parallel to the inner face of the cover D. A turned face on the cover comes into
rough contact with this web of the rubber ring, and the internal pressure forces it
into a joint practically sound against fluid at any pressure.

page_text: In applying our invention to the connection of pipes or tubes to each other, we
may form projections on the pipes in a similar manner to that described above,-
one pipe taking the place of the vessel, and the other that of the cover, and the
joint made being consequently of the spigot and socket type.
Alternatively we may make our improved joint, as shewn on Figs. 3 and 4,
between the butt ends, F and G, of the two tubes which are brought into contact
by means of a union H, having projections I at each end arranged to engage, in a
similar manner to that described above, with corresponding projections K on the
tubes, and provided if necessary with suitable elastic washers or rings L or other
ordinary means for making a sound joint.
We may make our improved joint of either glass, metal or any other material
suitable for the particular purpose for which the joint is intended to be used.
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. Couplings or joints for tubes and vessels, constructed, combined, and arranged
as and for the purposes described.
