PROVISIONAL SPECIFICATION.
Improvements connected with Couplings used with Flexible Hose..
I, EDWARD NUNAN, of 166 Fleet Street, City of London, Engineer do hereby
declare the nature of my said invention to be as follows:-
For the purpose of my invention I either arrange a lever, tumbler, bolt, crank,
or eccentric on or to a half coupling to engage in or between lugs or other pro-
jections or parts of the other half coupling, in order to enable the two half couplings
to be locked and so prevented from becoming detached should they accidentally get
loose at the joint, such as from the coiling or twisting of the hose or I fit a sleeve
ring over the neck of a hose coupling and attach the hose length to said sleeve ring,
so that the ring can turn on the coupling should the hose be twisted, the coupling
itself not being affected.
Each half coupling, interchangeable or other, may be similarly fitted.

COMPLETE SPECIFICATION.
Improvements connected with Couplings used with Flexible Hose.
I, EDWARD NUNAN, of 166 Fleet Street, City of London, Engineer, 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 object. To prevent kinks occurring in flexible hose.
For the purpose of my invention, I make the neck of one or of each half
coupling in two parts, so that one can rotate on the other, this rotatable part or
sleeve has the end of the hose secured to it, and not to the fixed part of the neck,
as is usual. This sleeve is ground internally to fit on the fixed neck to make it
watertight without interfering with its freedom to turn when necessary.
My sleeve or sleeves can be employed with any system of coupling but I prefer
their adoption to the methods described in my previous Patents Nos. 5272 of 1882;
16553 of 1884; 4503 of 1885; 13137 of 1888.
The annexed drawings show my invention.
Figure 1. half sectional elevation of a screw ferrule coupling having my sleeve
on each half.
Figure 2. half sectional elevation of sliding ring and clip coupling with my
sleeve on each half.
Figure 3. half sectional elevation of a rotating ring for acting on the tail ends of
the clips to bind the two half couplings together, these two half couplings have my
sleeves on their necks.
Figure 4. half sectional elevation of modified form of rotating ring, the pressure
being from two sets of inclined ribs to act simultaneously on the clips at both
their ends. This shows one sleeve only.
Figure 5. half sectional elevation of one half coupling and full elevation of the
other half coupling, both being of the same construction in every particular to be
interchangeable with each other, and each provided with the rotatable sleeve.
A, B, on all the figures are the two half couplings with rotatable sleeves C, D,
on the necks E, F. G. Figure 1 is a screw ferrule; at Figure 2 a sliding ring; at

half coupling. H, H, clips on one half coupling to be forced into grooves of the
other half coupling by the rings G for the attachment of one half coupling to the
other. I, 1, Figure 5, notched lugs on rotating rings G, G, on each half coupling
for engaging over inclined ribs J, J, of each other half coupling, each half coupling
being alike and interchangeable to one another. The sleeve may be on one half
coupling only, if desired.
The outer ends of the necks E, F, may be about flush with the sleeves, or it may
have a rib extending beyond the diameter of the sleeve, as at a, Figure 3.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is
1. Providing couplings with a rotatable sleeve on the neck for the attachment of
the flexible hose for the purpose set forth.
2. The several arrangements of coupling appliances shown on the annexed
drawings for connecting one length of hose to another length of hose, each
coupling or half coupling having a sleeve for the direct attachment of the hose end
and rotatable on a fixed neck, as described.
