PROVISIONAL SPECIFICATION.
Improved Attaching and Detaching Gear for Boats.
JAMES LINKLETER 3 Percy Street Tynemouth in the County of Northumberland
Patentee & Manufacturer do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in attaching & detaching gear whereby a
ring can be instantly secured by pressing it down on the hook so that it will not
detach itself, although it can be instantly detached even with the weight of the
boat on it.
To this end my invention consists of two cheeks between which is hinged a hook
on one pin, and a catch lever on the other.
In the two cheeks there is a recess to receive the lifting ring.
Above & partly overhanging the recess is the pin on which the hook is hinged,
the hook in front of pin projects over the recess, while it is weighted behind the
pin so that when the hook is forced down, by the ring passing into the recess, the
weight at back of hook brings it to its former position there it is held by coming in
contact with the lever catch.
The ring can be released at any time by lifting the lever which frees the back &
allows the hook to revolve on the pin & discharge the ring from its recess.
After which it comes back to its former position ready for reattachment.
When two hooks are fitted to work simultaneously the relative position of the two
hinges will vary, in the two hooks.
Dated this 21st day of October 1890.

COMPLETE SPECIFICATION.
Improved Attaching and Detaching Gear for Boats.
JAMES LINKLETER 3 Percy Street Tynemouth Patentee and Manufacturer 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 improvements in attaching and detaching hooks, whereby
a ring can be instantly attached by pressing it down on the hook and detached even
with the weight of the boat on it.
To this end my invention consists first of two cheeks between which is hinged
a hook on one pin and a catch lever on another, in the two cheeks is a recess to
receive the lifting ring, while above and partly overlapping the recess is the pin on
which the hook is hinged, this hook projects over the recess, in front of the pin and
is weighted behind the pin, so that when the hook is forced down by the ring
passing into the recess, the weight at back of hook bings it to its former position,
where it is held by coming in contact with the lever catch.
The ring can be released at any time by lifting the lever which frees the back
and allows the hook to revolve on the pin and discharge the ring from its recess,
after which it comes back to its former position ready for reattachment.
When two hooks are fitted to work simultaneously the relative position of the
two hinges will vary in the two hooks.
This will be better understood by reference to the drawings and descriptions.

page_text: DESCRIPTION OF DRAWINGS.
In each figure corresponding letters represent the same parts, C is the cheeks,
one of which is removed to show parts inside, R is the recess, H the hook, L the
catch, B the bolt through thwart and keel, and S is the lifting shackle or ring,
W is the wire connecting rope, and T a triangle spliced on the end, A is the
lever which gives the man aft control over both ends of the boat even with the
weight of boat and crew hanging in the tackles, K is the clip which holds and
releases the triangle.
Fig. 1. shows gear forward with catch lever and wire rope connection W, leading
aft with triangle T spliced on the end.
Fig. 2. is gear aft with lever A. pointing forward, the triangle T is attached to
the clip K. The catch L and clip K are so designed that the triangle leaves the
clip exactly as the back edge of hook leaves the catch L, thus releasing the two
shackles at the same time. Fig. 2. also shows the action of lifting shackle S,
passing into recess R, after which the heavy back of hook, weighs up the point
and locks the shackle in recess from which it cannot release itself, as shown in
Fig. 1. R and S.
The wire connection can either be worked straight fore and aft or through a pipe
attached to air boxes around the side of the boat.
A variety of forms of catch can be made where different results are required.
I do not tie myself to any particular form of catch.
I declare that what I claim is
Making an attaching and detaching gear with two recessed cheeks and short
pointed hook held by a catch.
