Complete Specification Left, 2nd Apr., -1897-Accepted, 19th June, 1897
Improvement in Couplings for Flexible Hose or Tube.
HENRY BINKO Electrical Engineer 34 Leadenhall Street London E.C. do
hereby declare the nature of this invention to be as follows:-
This improvement refers to a coupling for which a Patent was granted to
Edward Nunan of 166 Fleet Street E.C. No. 4503-1885.
In the specification of said patent the couplings are fully described showing
that they are thoroughly interchangeable & that packing-rings are provided to
each half-coupling to make the meeting-edges watertight."
Practice has proved that these packing-rings provided to each half of the
coupling soon wear out & so produce a leakage.
The object of my improvement is to avoid such leakage, & for that purpose I
provide a projecting ring or neck, to one half of the coupling, which presses on an
elastic ring fitted in a recess in the other half of the coupling.
It is obvious that by the application of this projecting ring, no matter how much
the elastic ring is worn, the coupling will still be watertight.
Dated this 2nd day of July 1896.

HENRY BINKO, Electrical Engineer 34 Leadenhall Street London E.C. 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 improvement refers to a coupling for which a Patent was granted to
Edward Nunan of 166 Fleet Street No. 4503-A.D. 1885.
In the specification of the said patent the couplings are fully described showing
that they are thoroughly interchangeable and that packing-rings are provided to
each half-coupling to make the meeting-edges watertight.
Practice has proved that these packing-rings provided to each half of the
coupling soon wear out & so produce a leakage.
The object of my improvement is to avoid such leakage and for that purpose I
provide a projecting ring or neck to one half of the coupling which presses on au
elastic ring fitted in a recess in the other half of the coupling.
It is obvious that by the application of this projecting ring, no matter how much
the elastic ring is worn the coupling will still be watertight.
In the drawing hereto annexed, A. A. shows the two halves of a coupling in
cross section B. B. shows the lugs for externally connecting the two half couplings
C shows the flexible ring or packing in the recess of one half of the coupling,
D shows the projecting ring or flange in the other half of the coupling.

page_text: I wish it to be understood that I do not restrict myself to the exact construction
of parts shown in the drawing, but may vary the same so as to better carry out
the principles of my improvements without departing from the true scope
thereof.
Having now particularly described & ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improvement in the projecting ring or flange in one half of the coupling,
in connection with the coupling constructed according to Patent No. 4503-
A.D. 1885.
