PROVISIONAL SPECIFICATION.
Improved Automatic Detaching Gear for Ships' Boats.
I WILLIAM MADDISON WARD of Low Quay Blyth in the County of
Northumberland Merchant do hereby declare the nature of this invention to be as
follows
This invention refers to improvements in and relating to boat detaching gear to
effect which I pivot between two sides or carriers (fixed in any suitable position of
the boat) at their upper end a bar made of iron or other suitable metal, the upper
part of which is shaped like an ordinary hook, the other end is curved in such a
way that the lower end projects through a loop or eye, also pivotted between the
carriers.
Pivotted on the lower part of the bar in a suitable position, I place for the
purpose of a mousing two pieces of iron or suitable metal (one on each side) and
rivetted together somewhat in the shape of a fitter's square the base of which is
heavier than the perpendicular and which base rests on the loop, the bolt or pin
running through the two at the corner of the base and perpendicular.
For the purpose of automatic and simultaneous action of the fore and after hooks
from the aforementioned loop on the keelson of the boat underneath each hook is
placed a crank connected by a longitudinal rod, from the other end of each crank is
a vertical rod connected to the end of each loop and weighted.
When the weight of the boat is on, the loop is kept up by the pressure of the
tail of the hook against the loop. When the boat is waterborne the pressure ceases
and allows the loop to fall which releases the mousing, and also causes the hook to
free the tackle by being overturned, the loop at the other end of the boat being
connected by the rods and cranks, falls also, thus both ends of the boat are freed
simultaneously.
When the boat is only waterborne at one end, the loop at the other end holds
fast until both ends are waterborne.
To prevent misuse a toggle pin is inserted below the loop which must be removed
on lowering the boat, and put in again before hooking on.

COMPLETE SPECIFICATION.
Improved Automatic Detaching Gear for Ships' Boats.
I WILLIAM MADDISON WARD of Low Quay Blyth Northumberland Merchant
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 :-
The enclosed drawings on being referred to will describe the means I employ to
carry out my invention.
Fig. 1. shows in what manner the hooks are connected. Upon the keelson at
each end of the boat are fixed the cranks B B connected by a longitudinal rod H.
From the extremity of each crank rise two vertical rods E E the upper ends of
which are connected to the detaching loops F F. The detaching power is caused
by the weight W fixed on the stern vertical rod.
Fig. 2 is a side view of the stern hook.
Pivotted between the two sides A at their upper end, is a bar of iron shaped like

page_text: an ordinary hook at its upper end C, the other end D being curved in such a way
that it projects through the loop F which is also pivotted between the sides A.
Pivotted on the lower part of the bar D above the curve is placed for the
purpose of a mousing, two pieces of iron T (one on each side of the hook) shaped
something like a fitter's square, the base being heavier than the perpendicular, the
former resting on the loop F, the pin or bolt running through the two at the corner
of the base and perpendicular.
When the weight of the boat is on, the loop F is kept up by the pressure of the
tail of the hook D against the loop F.
When the boat is waterborne the pressure ceases and allows the loop F to fall
clear of the hook point D, releasing the mousing T and causing the hook C to free
the tackle by being overturned, the loop at the other end of the boat being con-
nected by the rods and cranks as shown in Fig. 1, falls also, thus freeing both ends
of the boat simultaneously.
When the boat is only waterborne at one end, the loop at the other end holds
Iast until both ends are waterborne.
Fig. 3 is a side view of the fore hook.
To prevent misuse a toggle pin G is inserted below the loop F which must be
removed on lowering the boat and put in again before hooking on.
In hooking on it is only necessary to press the tackle ring against the mousing T
which allows it to enter the hook when ou account of its weighted end immediately
regains its position.
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-
1st. The use of a hook as shown in drawing.
2nd. The use of a mousing formed by two pieces of iron or other suitable
material (one on each side of the hook) and rivetted together and shaped something
like a fitters square being pivotted at the corner of the base and perpendicular, and
having the base heavier than the perpendicular, which base rests on a loop or other
foundation.
