PROVISIONAL SPECIFICATION.
Improved Means for Securing End Loops of Ropes or Chains.
I, EDWARD DOUGLAS, of 327 South John Williamson Street, South Shields
in the County of Durham, Trimmer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to means for securing end loops of ropes or chains when
used to make fast one object to another e.g. a ship to a mooring post and has for its
object. to provide a simple and efficient device which can be quickly fixed and
released and which is inexpensive to produce..
According to my invention at any distance on the end of the rope which may be
required to form the end. loop I fix a tapered metal stop piece or equivalently a
cylindrical stop with à flange at its outer end.
To the end of the rope I fix by a thimble and ring or otherwise a corresponding
tapered sleeve or a cylindrical sleeve with a slot in its wall extending its full
Jength; this slot is of such width as to receive any required rope or chain and
the sleeve is adapted to pass over the aforesaid stop piece and fit and be firmly
held thereby.
In use any part of the rope, outside the stop piece is passed through the slot of
the holder sleeve or piece and then any subsequent pull on the loop serves to
draw the slotted sleeve along the rope and engage it firmly on the fixed stop and
a secure connection is effected.

$
The unfastening is accomplished on the slacking of the rope or chain.
When my invention is employed with a chain the parts are so formed as to: fit
the conformation of the links and act in the same manner as above described.

Improved Means for Securing End Loops of Ropes or Chains.
1, EDWARD DOUGLAS, of 327, South. John Williamson Street, South Shields
in the County of Durham, Trimmer, 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 relates to means for securing end loops of ropes or chains when
used to make fast one object to another, for example, a ship to a mooring post, a
horse to a balk of timber and so forth, and has for its object to provide a simple
and efficient device which can be quickly fixed and released and which is
inexpensive to produce.
According to my invention, at any distance from the end of the rope which may
he required to form the loop end, I fix a tapered metal stop piece, or equivalently,
a cylindrical stop with a flange at its outer end.
To the end of the rope, I fix by a thimble and ring or otherwise a corresponding
tapered sleeve or a cylindrical sleeve, with a slot in its wall extending its full
.

page_text: length; this slot is of such width as to receive any required rope or chain and the
sleeve is adapted to pass over the aforesaid stop piece and fit it and be firmly
held thereby.
I will fully describe my invention with reference to the accompanying drawings
in which Figures 1 and 2 show respectively the parts detached and attached.
Where thick ropes are used it is convenient to use a chain or two thinner ropes
for the loop and this latter arrangement I have illustrated.
A is the stop piece and a its flange. It is shown tapered as being the preferred
construction, though it may be parallel sided as shown in dot-and-dash lines in
Figure 1. It is fixed by countersunk headed rivets or other suitable means to the
rope R at any convenient distance from the free end required to form any sized
loop.
B is the correspondingly shaped and sized sleeve with longitudinal slot 6 of
width equal to, or slightly greater than, the diameter of any rope or chain to
which the stop A is fitted. It is secured to the rope end as shown in the drawings
or in any other practical manner.
In use, the loop is passed round the bollard C or equivalent object and the
slot in the sleeve B is then passed over any part of the rope R outside the stop
piece A and then a subsequent pull on the loop serves to draw the sleeve up the
rope and over the stop until its upper end engages below, the flange a of the
stop A as shown in Figure 2 and a perfectly secure fastening is effected.
:
The unfastening is accomplished on the slacking of the rope or chain and may
be aided if desired by the use of a short tug piece as shown at T in Figure 2.
When my invention is employed with a chain the sides of the slot & and the
required parts are
so formed as to fit the conformation of the links and act
precisely in the manner herein before described.
'
By my invention there is no loose piece such as the usual pin used with a
shackle which is frequently lost in unfastening and the like.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The means for securing end loops of ropes or chains wherein a hollow slotted
sleeve B secured to the rope or chain end is used in connection with a corre-
spondingly shaped flanged stop piece A fixed to the rope or chain at any distance
from its end, the two parts being arranged and adapted to operate substantially as
above described and illustrated in the drawings.
