PROVISIONAL SPECIFICATION.
Improvements relating to Apparatus for Closing the Watertight
Doors and Valves of Ships.
FREDERICK WILLIAM SLAUGHTER, 76, Breakspear Road, Brockley,
London, S.E., Engineer, do hereby declare the nature of this invention. to be as
follows:-
This improvement has for its object the means of closing more quickly the water-
tight doors, and valves, in ships by a combination of deck-box and spanner, so that
in a case of emergency the spanner to fit on the spindle, being contained in the
deck-box may be more readily at hand for the purpose of screwing down the door,
or valve.
A loose spanner is preferred or it may be made to swivel on end of spindle, or be
made folding.
I also prefer to construct the deck-box with a hole in the bottom for the handle
of the spanner to pass through, and the loose spanner by preference cranked, with
a socket to fit the top of the spindle.
Between the socket and handle a ring, or hole is formed with its axis at right
angles to the socket, which hole is for the purpose of slipping over the spindle, thus
allowing the cranked part of the spanner to lie low in the box, the handle
projecting through the bottom and enabling a small, and light size of box to be
used.
This arrangement allows the cover to be screwed on the top of the box and all
be flush with the deck.
And in such cases where the box is placed in a manner that would prevent the
spanner from making a complete revolution, a vice handle spanner may be used
which when required to be packed away, the small part of the handle is passed
through the bottom of the deck box while the socket is placed at right angles or is
inverted and slipped over the spindle.

COMPLETE SPECIFICATION.
Improvements relating to Apparatus for Closing the Watertight
Doors and Valves of Ships.
FREDERICK WILLIAM SLAUGHTER, 76, Breakspear Road, Brockley, S.E.,
Engineer, 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 :-
This improvement has for its object the means of closing more quickly the water-
tight doors and valves in ships by a combination of deck box and spanner, so that
in a case of emergency the spanner to fit on the spindle being contained in the box,
may be more readily at hand for the purpose of screwing down the door or valve.
A loose spanner is preferred, or it may be made folding, I also prefer to construct
the deck box with a hole in the bottom for the handle of the spanner to pass
through, and the loose spanner by preference cranked, with a socket to fit the top
of the spindle.
Between the socket and handle a ring or hole is formed with its axis at right
angles to the socket, which hole is for the purpose of slipping over the spindle, thus

page_text: allowing the cranked part of the spanner to lie low in the box and the handle
projecting through the bottom, and enabling a small and light size of box to be
used.
This arrangement allows the cover to be secured on the top of the box and all
be flush with the deck.
And in such cases where the box is placed in a manner that would prevent the
spanner from making a complete revolution, a vice handle spanner may be used;
which when required to be packed away, the small part of the handle is passed
through the bottom of the box while the hole in the handle near the socket is
slipped over that part of the spindle contained in the box.
Fig. 1 of the accompanying drawings is a vertical section of a deck box showing
the cranked spanner stowed away according to my invention.
Fig. 2 is also a vertical section with cover removed, showing position of spanner
when in use.
Fig. 3 is a plan of Fig. 1.
Figs. 4 and 5 are a modification, forming a vice handle spanner which may be
stowed away in a similar manner.
Figs. 6 and 7 are also a modification of Fig. 1 and Fig. 2 showing a folding
spanner in use and packed away respectively.
In Fig. 1 the handle A of the spanner B. is passed through a hole C in the
bottom of the box D while a hole E in the spanner B is slipped over the spindle F
which is used for screwing down the door or valve.
The hinge ring G as shown in plan in Fig. 3 is used for screwing or unscrewing
the cover H.
In Fig. 4 a vice handle spanner J is shown packed away in a similar manner.
In Fig. 6 the handle L may be drawn through the rod P, and when required to
be packed away is threaded through the hole Ñ as shown in Fig. 7.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that wha I
claim is :-
1. A method of containing in a flush deck box the head of a valve spindle and a
key or spanner, for the purpose of actuating it, thus preventing the key or spanner
being mislaid.
2. A combination of deck box and spanner so constructed to give ea access to
the key or spanner and spindle and at the same time forming a compact dush-deck
box to contain the said key or spanner.
3. The improved construction substantially described with reference to the
Figs. 1 to 7 of the accompanying drawings, and operating for the purpose as above
specified.
Dated this 16th day of February 1891.
