AN IMPROVEMENT IN BOAT LOWERING TACKLE
Year: 1885

page_text: I, EDWARD JACOB HILL of N° 6 Westminster Chambers, Victoria Street in the
City of Westminster, Engineer, do hereby declare the nature of my said invention
for "AN IMPROVEMENT IN BOAT LOWERING TACKLE" to be as follows:-
My invention relates to an improvement in the boat lowering and detaching
apparatus for which Letters Patent were granted to me dated January 24th 1872
No 242 and it has for its object to facilitate the attachment of the fore and aft
safety line or other means of connecting the two tackles so that a part of the
strain on each shall be transferred to the other in order to prevent the premature
release of one end of the boat.
The invention consists in providing the slip ring employed in connection with
the peculiar slip hook forming the subject of my previous patent aforesaid with an
eye link or shackle jointed thereto for attachment to the lower block of the tackle,
said eye link or shackle having duplicate downwardly pointed hooks one at each
side, so that it matters not which side of the slip link is passed onto the slip hook
first, either of the said hooks serving for the attachment of the fore and aft safety
line or of the standing part of the other tackle, according to the arrangement
adopted for transferring the strain from one tackle to the other. In order however
that the one of the said hooks which is not in use for the time being shall not foul
the point of the slip hook, the said downwardly projecting hooks are not in the
plane of the eye or link or shackle to which they are attached, but are bent
sufficiently to one side to ensure their points passing clear of that of the slip hook.

I, EDWARD JACOB HILL of N° 6, Westminster Chambers, Victoria Street, in the
City of Westminster, 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 :-
My Invention relates to the boat lowering and detaching apparatus for which
Letters Patent were granted to me dated January 24th 1872 and numbered 242;
and it has for its object to facilitate the attachment of the fore and aft safety line,
or other means of so connecting the two tackles that a part of the strain on each
shall be transferred to the other, in order to prevent the premature release of one
end of the boat.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein Figure 1. shows the disengaging gear at one end of a boat;
Figure 2 shows, on a larger scale, a face view, and Figure 3. a plan of the part of
the gear to which my present Invention relates. Figures 2 and 2b show top and
side edge views of the said part separately. The same letters of reference indicate
the same parts in all the Figures.
a is the peculiar slip-hook forming the subject of my previous Patent aforesaid;
b is the slip-ring employed in connection therewith, and c is an eye link or shackle
connecting the slip-ring 6 to the lower or running block d of the boat lowering
tackle, e is the fore-and-aft safety line connecting the links c of the two tackles
which are alike in every respect. The present Invention consists in providing the
eye link or shackle c with duplicate downwardly pointed hooks ff' one at each
side, so that it matters not which side of the slip-link b is first passed on to the
slip-hook, as either of the said hooks f will serve for the attachment of the fore and
aft safety line e, as shown; or for the attachment of the standing end of the fall of
the other tackle; (as described in another application for letters Patent of even
date here with and numbered 5444) whichever arrangement may be adopted for
transferring the strain from one tackle to the other. In order however that the
one of the said hooks, which is not in use for the time being, shall not foul the
point of the slip hook a, the hooks ff¹ are not in the plane of the eye link, or
shackle b on which they are forged, but are bent sufficiently to one side to ensure
the point of the hook f which is not in use passing clear of that of the slip-hook,
when the automatic release of the boat takes place.
Having now particularly described and ascertained the nature of the said inven-
tion; and in what manner the same is to be performed; I declare that what
I claim is
1. In a boat-lowering and detaching gear of the kind herein referred to the com-
bination with the eye link, or shackle, connecting the slip-ring with the running

page_text: block, of a pair of downwardly pointed hooks, one at each side of the said eye link
or shackle, said hooks extending in a fore and aft direction (for the connection of
the fore and aft safety line, or the standing end of the fall of the other tackle) and
being bent out of the plane of the eye link, or shackle, by which they are carried,
5 so that the hook not in use shall not foul the point of the slip hook, substantially
as specified.
