PROVISIONAL SPECIFICATION.
An Improved Sliphook for Connecting and Disconnecting
Ships' Boats.
WILLIAM MADDISON WARD Low Quay Blyth Northumberland Merchant
and THOMAS INNES GRAY 108 Bowes Street Blyth Northumberland Blacksmith,
do hereby declare the nature of this invention to be as follows :—
Over the top of a double eye or two sides (as supports) is formed a fixed link or
staple from one side to the other, through these sides in a convenient position a pin
or bolt is fixed, and pivotted on this pin or bolt and working between the two sides.
is a moveable bar forming a hook at one end, the end of the hook pointing through
the link or staple, the other end of the bar is weighted to be heavier than the hook
end causing the point of the hook to enter between the link or staple thus forming a
mousing.
We make the hole in the hooked bar through which the pin or bolt goes
"elongated
or larger in diameter than the pin, this, when the weight of the boat is
on throws the strain equally between the base & point of the hook by allowing the
point to jamb itself under the link or staple. To hook on lift the weight and insert.
the ring on lower tackle between point of hook and link or staple. To release lift
the weight.

COMPLETE SPECIFICATION..
An Improved Sliphook for Connecting and Disconnecting
Ships' Boats.
We WILLIAM MADDISON WARD of Blyth Northumberland Merchant and
THOMAS INNES GRAY of 108 Bowes Street Blyth Northumberland Blacksmith,
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 we employ.
to carry out our invention.
Fig. 1 is a side view.
Fig. 2 is a sectional side view of our invention.
A A is a long double-eye forming at the top a fixed link from one side to the
other, B is a hole through the two sides, and on the sides opposite the link two studs.
are formed.
Through the hole in the two sides a bolt is fixed, and pivotted on this bolt and
working between the two sides is the hook C D one end of which (C) is pointed
through the link A, the other end D is weighted to keep the hook in position.
At the lower part of the hook C_D, and about mid-way between the hook and
weighted end, is formed the tongue E, and pivotted at the end of the tongue E is the
rod F, and from the end of the rod F and leading through the bottom of the double-
eye A is the weight G, which is hung by a lanyard or other suitable appliance.
The hole H on Fig. 2 is elongated or larger in diameter, than the bolt on which
the hook CD is pivotted, so that when the weight of the boat is on, the point of
the hook grips under the link A thus dividing the weight between the base and end
the hook.

page_text: For the purpose of detaching, when the boat is lowered, a lanyard is fixed to
the end of the rod F, attached to the hook at each end of the boat, terminating in a
handle, which, when pulled opens both hooks simultaneously, thus detaching the rings
of the lower tackle blocks.
Fig. 3, shows the hook opened and the ring disengaged.
Fig. 4, shows the act of re-engaging, the inside of the hook and the inside of the
studs (when the hook is open) form a wedge shaped guide, so that when the ring is
inserted, its weight, or the force with which it is inserted closes the hook, which
owing to its weighted end D is kept in that closed position under the link A thus
securely mousing it.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The use of a pivotted hook having an elongated hole, or one of larger diameter
than the bolt on which it is pivotted, for the purpose of allowing the hook to grip
under a link.
2. The use of a double-eye with a link connected from one side to the other.
3. The use of two short studs forming a wedge shaped guide between themselves
and the inside of the before mentioned hook.
