An Improvement in Swivels.
Year: 1893

page_text: Date of Application, 19th Sept., 1893
Complete Specification Left, 16th June, 1894-Accepted, 21st July, 189
I, GEORGE MORISON HAMLYN, of No. 6 Crosby Square, in the County of
London, Ship Broker, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the construction of a swivel in such a manner that a rope
or cable can be passed through it without interfering with the relative movements
of the two parts of the swivel.
For this purpose, I make the one loop of the swivel terminate in a ring having a
projecting boss formed with a projecting collar, and I make the other loop also
terminate in a ring having an internal groove adapted to embrace the collar above
mentioned. I divide this second ring and open it out so as to pass its mouth over
the collar, and then close it in, the collar being thus engaged in its groove. To
prevent the divided ring from reopening I shrink over it an outer ring. The collar
of the one ring being free to revolve in the groove of the other, the two loops of
the swivel which are respectively attached to the two rings can turn relatively to
one another, while a rope or cable is passed through the open middle of the
inner ring.
Dated this 19th day of September 1893.

COMPLETE SPECIFICATION.
An Improvement in Swivels.
I, GEORGE MORISON HAMLYN, of No. 6 Crosby Square, in the County of
London, Ship Broker, 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 :-
My invention relates to the construction of a swivel in such a manner that a
rope or cable can be passed through it without interfering with the relative
movements of the two parts of the swivel.
For this purpose I construct a swivel as shewn in the accompanying drawing in
side view partly in section by Fig. 1, and in plan by Fig. 2 which is a section
on X X of Fig. 1. I make the one loop A of the swivel terminate in a ring having
a projecting boss B formed with a projecting collar C; and I make the other
loop D also terminate in a ring E having an internal groove adapted to embrace
the collar C. I divide the ring E and open it out so as to pass its mouth over the
collar C and then I close it in, the collar being thus engaged in its groove. To
prevent the divided ring E from reopening, I shrink over it an outer ring F. The
collar C of the boss B being free to revolve in the groove of the ring E, the two
loops A and D of the swivel can turn relatively to one another, while a rope or
cable G is passed through the open middle of the boss B. A number of shackles
such as H may be engaged on the loops A and D, but, instead of engaging several
mooring shackles on D, all of which might have to be separately detached, I prefer
to connect to D by a single shackle H a cage K with which two or more mooring
shackles H2 are engaged. Thus in order to detach the swivel from the moorings,
only the single shackle H' has to be disengaged.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A swivel consisting of two loops attached to rings, the one ring having a boss
with a projecting collar engaged in a groove of the other ring which is put on in
halves and held by an outer ring shrunk on, substantially as described.
Dated this 16th day of June 1894.
