PROVISIONAL SPECIFICATION.
Improvements in Boat Detaching Apparatus.
I, EDWARD JACOB HILL, of 6 Westminster Chambers, Victoria Street, in the City.
of Westminster, Engineer, do hereby delare the nature of this invention to be as.
follows:-
My Invention relates to improvements in the Boat-Detaching gear for which former
Letters Patent were granted to me dated the 22nd day of November 1886 No. 15196
and it has for its object to simplify the construction of the carrier and hook in
which it slides and to strengthen both of these pieces, and also to provide a more
secure and easily operated locking device. To this end, I dispenso with the slot and
pin connection which in my former invention limited the endwise movement of the
carrier, and I connect a slotted link by a pin to the end of the carrier, said link being
long enough to bridge the slot in the hook in which the carrier slides. The slot in
the link extends from near one of its ends to about its mid-length so that it may
be drawn into the slot in the hook when the carrier is moved to open the hook, or it
may be placed at right angles across the slot in the hook when the carrier is within
the hook and thus lock the carrier in that position.
The link would be provided with a ring at the opposite end to the slot, serving as
a stop for the carrier in the open or unmoused position and for the attachment of a
connecting line.

COMPLETE SPECIFICATION.
Improvements in Boat Detaching Apparatus.
EDWARD JACOB HILL of 6 Westminster Chambers, Victoria Street, in the City
Westminster, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained'
in and by the following statement :-
My invention relates to improvements in the Boat-Detaching gear for which former
Letters Patent were granted to me dated the 22nd day of November 1886, No. 15196,
the said gear consisting of hooks fixed in a fore and aft position at the bow and
stern of the boat, for- engagement with rings or shackles attached to the lower or
running blocks of the boat lowering tackles. In each of these hooks a plate is fitted
to slide in a fore and aft direction, the said plate being adapted to act as a mousing
5to close the mouth of the hook when the tackle ring is engaged therewith, and also
as a carrier or traverser to disengage the tackle ring from the hook in the operation
of detaching the boat.
The present invention has for its object to provide a more secure and easily operated
locking device for the said sliding traverser or mousing and also to simplify the
construction of the traverser and increase the strength of the parts.
Reference is to be had to the accompanying drawings forming part of this
specification in which figure 1 shows one of the hooks with the improved locking
device applied to the sliding traverser and mousing, the parts being in the locked
position. Figure 2 is a similar view, the mousing being unlocked and ready to be
disengaged whilst Figure 3 shows the position after disengagement of the hook from
the boat lowering tackle.

page_text: A is one of the fore and aft hooks B the ring or shackle attached to the running
block of the tackle and C the notched plate fitted to slide through a fore and aft
mortise in the hook and adapted to act as a mousing to retain the ring B in the
hook A and also as a means of carrying said ring clear of the hook in disengaging
all as described in the specification of my said former patent. D is the improved
locking device for the mousing plate C. It consists of a longitudinally slotted plate
received in a fork e at the rear end of the plate C and connected thereto by a joint pin c¹
passing through the slot in the said locking plate. This slot extends from near one
end of the plate D to about the middle of its length and the plate is long enough
when placed at right angles to the carrier plate as shown in figure 1 to bridge across
the end of the mortise in the hook A in which the traverser C slides and prevent any
motion of the traverser which is thus locked. The locking plate D when placed in
the position shown in figure 2 opposes but a slight resistance to the movement
of the traverser as it is free to be drawn into the mortise in the hook immediately a
forward pull comes on the traverser C. The locking plate D is provided with an eye
at the end opposite to the slot for the connection of a ring e and cord, the ring serving
as a stop to limit the motion of the traverser as shown in figure 3. The traverser
of the bow hook is connected to that of the stern hook and the two are adapted to be
operated simultaneously for the purpose of disconnecting the boat either by the pull
on the boat's painter by the coxswain of the boat or by a man on the ship, the
operation in that respect being similar to that described in the specification of my
previous patent.
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―
The combination with the herein described hook and traverser or mousing of the
herein described locking device consisting of a plate connected to the sliding traverser
or mousing and adapted to be placed in the positions herein described with regard
thereto and to the hook substantially as and for the purpose specified.
