I, WILLIAM HORATIO HARFIELD, of Mansion House Buildings, in the city of
London, Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
Hitherto Bow or fore Bitt Stoppers for chain cables have been placed between the
hawse pipe and the Riding Bitts. In such stoppers as generally constructed the chain
passes over the whole length of the stopper, the vertical links running in a longitudinal
groove continued to the fore end of the stopper.
My improvements consist in stopping the groove considerably short of the end of
the stopper and forming a large pipe or hole in the fore end of the stopper through
which the chain passes and which forms the inboard flange of the hawsepipe.
Further, stoppers as commonly constructed, have only one straight lead corre-
sponding with the longitudinal groove and when there are two leads one to the
Capstan and one to the chain lockers it has been necessary to place a bollard or roller
between the Bow Stopper and the Capstan which entails considerable expense.
In order to dispense with the necessity of using a bollard or roller,
lead on the stopper itself which enables the chain (after leaving the holding part of
the stopper) to be led in any required direction, thereby effecting economy in both
cost and deck space.
I form a fair-

page_text: I, WILLIAM HORATIO HARFIELD, of Mansion House Buildings, in the city of
London, Mechanical 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
n and by the following statement :-
Hitherto bow or fore bitt stoppers for chain cables have been placed between the
hawse pipe and the riding bitts. In such stoppers as generally constructed the chain
passes over the whole length of the stopper the vertical links running in a longitudinal
groove continued to the fore end of the stopper.
My improvements consist in stopping the groove considerably short of the end of
the stopper and forming a large pipe or hole in the fore end of the stopper through
which the chain passes and which forms the inboard flange of the hawse pipe."
Further, stoppers as commonly constructed have only one straight lead corre-
sponding with the longitudinal groove and when there are two leads of the cable,
videlicet, one to the capstan and the other to the chain lockers, it has been necessary
to place a bollard or roller between the bow stopper and the capstan which entails
considerable expense.
In order to dispense with the necessity of using a separate hollard or roller, I form
or attach a fairlead on the stopper itself which enables the chain (after leaving the
holding part of the stopper) to be led in a side direction thereby effecting economy in
both cost and deck space.

In order to enable my invention to be fully understood I will proceed to describe
how it may be carried into effect by reference to the accompanying drawing in which
figure represents a plan, figure 2, a longitudinal section and figure 3 a back view
of a cable stopper constructed with my improvements. In figure 2 the stopper is
shewn with a chain cable placed therein. Similar letters in all the figures represent
similar parts.
A, represents the stopper proper and A', the longitudinal groove thereof which
(as clearly shewn in figures 1 and 2) is stopped considerably short of the fore end of
the stopper; B, is the large pipe or hole which I form in the fore end of the stopper,
such hole B, forming the inboard flange of the hawse pipe C, through which the chain
cable B', passes. In the drawing the stopper A, and the pipe or flange B, are shewn
cast in one, but it will be obvious that the pipe or flange can if required be cast
separate from the stopper proper; the line a, y, figure 1, shews where the two parts
can be conveniently divided and when in use they are brought together and bolted
in place. D, is the fairlead which I form on or attach to one side of the stopper A,
such fairlead allowing the cable B¹, (after leaving the holding part of the stopper) to
be led in a side direction thereby effecting economy both in cost and deck space.
E, is the ordinary tripping lever of the stopper. F, is the usual bow.

page_text: 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 :-
1. Providing bow or fore bitt cable stoppers with a hole or pipe formed at the
fore end of the stopper substantially as and for the purpose hereinbefore described and
illustrated in 'the acconipanying drawing.
2. Providing bow or fore bitt cable stoppers with a fairlead for guiding the chain
in a side direction after leaving the stopper, substantially as hereinbefore described
and illustrated in the accompanying drawing.

3. The improved cable stopper herein before described and illustrated in the
accompanying drawing.
