JOHN COSENS High Street Hythe Southampton Hants no occupation I do hereby
declare the nature of this invention to be as follows:-
First. Two hooks fastened together by a pin, and weighted in such a manner, at the
upper ends, that on the strain of the Boat, or weight being removed they instantly free
themselves thereof.
Secondly. The shape of the Hooks at the lower end are so formed that any weight
must clear itself, and also in Hooking on one hook must close on the other instantly on
strain being applied.
Thirdly. To the head of one is applied a safety stop through which a pin is passed
going through a hole in the head of second hook to prevent them becoming unhooked
accidentally.
Fourthly. To the safety Pin is attached a Lanyard, which enables one man to free
both ends of Boat at the same time, either by hand or, in case of large boats by a Crank
or Lever fixed in the boat, to prevent the danger of one end of boat being free and the
other not.

page_text: JOHN COSENS High Street Hythe Southampton Hants no occupation I do hereby
declare the nature of this invention and in what manner the same is to he performed,
to be particularly described and ascertained in and by the following statement :-
First. Two hooks fastened by a pin together, and weighted in such a manner at the
upper ends that on the strain of the boat, or weight being removed, they instantly free
themselves thereof.
Secondly. The shape of the hooks at the lower end are so formed that any weight
must clear itself, and also in hooking on, one hook must close on the other instantly on
strain being applied.
Thirdly. To the head of one is applied a safety stop through which a pin is passed
going through a hole in the head of second hook, to prevent them becoming unhooked
accidentally.
Fourthly. To the safety pin is attached a lanyard which enables one man to free both
ends of boat at the same time either by hand or in case of large boats by a crank or
lever fixed in the boat, to prevent the danger of one end of boat being free and the
other not.
Fifthly. On the principal hook of the larger sizes a stop or projection is placed to
take the strain from the bottom of the hooks-this is not essential in the smaller sizes,
they can be made either with or without it.
Sixthly. The hooks can be of any size and strength.
In the accompanying drawings
Fig. 1. shows the front view of hook closed showing safety pin and detaching
lanyard.
Fig. 2. shows the back view of Hook open showing the stop, D.
Fig. 3. shows the safety pin.
A A A A. shows the balanced ends which open the hooks on reliet' of strain.
B B B B. shows the strengthning peices for the shoulders, and also to clip the
hooks.
C. C. shows the stop through which the safety pin passes to lock the hooks.
D. shows the stop to prevent the hooks overlopping and to take some strain in the
larger sizes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. That the shape of the hooks are such that a boat, or other weight will become
detached immediately on the strain being taken off.

page_text: 2. The safety pin will prevent the hooks detaching themselves before being required
to do so.
3.
The lanyard attached to the pin will enable one person to free both ends of boat
at one and the same time, and so prevent one end being free and the other not, on the
boat becoming water borne.
4. In hooking on one part must close on the other immediately strain is applied.
5. In cases of danger. The pin and lanyard will enable the hooks to be freed at a
distance without risk to the person freeing them.
