Improvements in and connected with Ships' Water Closets.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co of Deptford in
the County of Kent Engineers and EDWIN WILLIAM DE RUSETT of Warden
House Percy Park Road Tynemouth in the County of Northumberland Naval
Architect do hereby declare the nature of this invention to be as follows:-
Heretofore where a number of water closets have been fitted which derive their
water supply at varying distances from the same source it has been found necessary
to fit each water closet with a stop valve for regulating the flushing action of the
flushing or supply valve according to the varying conditions under which they
severally are placed or fitted This is more especially the case on board large
ships. Now according to this invention the necessity for regulation by means of
such stop valves is obviated by the application to the supply valve lifting spindle
of an adjustable attachment to which the actuating tumbler lever is connected for
the purpose of altering as required the amount of lift of the valve. In one form or
arrangement the outer end of the supply valve actuating spindle is formed with
screw thread and is by two screw uuts fixed in a sleeve o socket provided with a
slot for the end of the tumbler lever to work in. The spindle passes through &
stuffing box and its inner end works against the ball or other flushing valve By
means of the nuts one above and one below the said socket the position of the
latter on the spindle can be adjusted for the requned amount of lift of the
valve.
To prevent the inrush of water we provide in connection with the pull up handle
attached to the discharge valve a trigger o catch whereby the said valve is fimly
secured in its place wheu on its seating When however the pull up handle is being
aised the trigger or catch is thereby released, thus allowing the contents of the
closet to be discharged.
In one form of trigger we make the pull spindle in two parts, an inner one to
which the handle is attached and an outer one or sleeve to the lower end of which
the valve is connected. The inner spindle is connected to the sleeve by a pin in
the sleeve working in an elongated slot in the spindle On the pin is fitted so as
to turn freely a trigger having an upper lateral projection which can look into
recess or slot in the inner spindle and a lower lateral projection which can enter a slot
in the sleeve and hook under the cup which is fixed to the after flush box. When
the pull handle is in the down position the trigger hooks into both places thus firmly
connecting the sleeve with the said cup and keeping the valve tightly closed.
When the pull is raised the trigger turns on its pin whereby tle upper hook part is
drawn out of its recess and the lower hook similaily out from under the cup and when
the pin has come to the bottom of its slot the spindle carries the sleeve up with it and
thus raises the valve. The weight of the spindle 18 such as to normally keep the
sleeve locked and the valve closed.
In cases where the closet is fitted near the water line, in addition to the valve
connected to pull-up handle above mentioned we sometimes fit a self-acting Hap
valve in lower part of closet, secured in its place by wedges, springs, or other
suitable means, and so ai ranged that when the pull up valve is raised, it will prevent
the inrush from the sea from entering the closet pan, as the self acting flap valvo

page_text: will be closed against it, whilst it will open automatically to allow the contents of
closet to pass away to the ship's side.

We, EDWIN JAMES PRESTON, of the Firm of J. Stone & Co, of Deptford, m
the County of Kent, Engineers, and EDWIN WILLIAM DE RUSETT, of Warden
House, Percy Park Road, Tynemonth, in the County of Northumberland, Naval
Architect, 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.-
Heretofore where a number of nater closets have been fitted which derive their
water supply at varying distances from the same source it has been found necessary
to fit each water closet with a stop valve for regulating the flushing action of
the flushing or supply valve according to the varying conditions under which
they severally are placed or fitted. This is more especially the case on board
large ships.
Now according to this invention the necessity for regulation by means of such
stop valves is obviated by the application to the supply valve lifting spindle of an
adjustable attachment to which the actuating tumbler lever is connected for the
purpose of altering as required the amount of lift of the valve.
Fig. 1 is a front view and Fig. 2 a side view of one form of arrangement, the
valve being in the closed position with full lift; Fig. 3 is a front view, the valve
being in the open condition, with reduced length of lift The outer end of the
supply valve actuating spindle A is formed with screw thread and 13 by two
screw nuts B and C fixed in a sleeve or socket D provided with a slot E for the
eud of the tumbler lerei F to work in The spindle A passes through a stufling
box and its inner or upper end works against the ball or other flushing valve in
the casting G By means of the nuts B and C one above and the other below
the socket D the position of the latter on the spindle can be adjusted according
to the required amount of lift of the valve. the stop washer N prevents the lift of
valve being increased beyond its full travel.
To prevent the inrush of water from the sea from lifting the pull up valve,
we provide in connection with the pull up handle attached to the discharge
valve a trigger or catch whereby the said valve is firmly secured in its place
when on its seating. When however the pull up handle is being raised, the
trigger or catch is thereby released thus allowing the contents of the closet to be
discharged.
Fig. 4 is a vertical section through a pull up handle and spindle with one form
of trigger and Fig. 5 is a vertical section of the inuer spindle H. We make
the pull spindle in two parts an inner one H to which the handle is attached
and an outer one or sleeve I to the lower end of which the valve is connected.
The inner spindle II is connected to the sleeve I by a pin K in the sleeve working
in a slot II in the spindle H. On the pin is fitted so as to turn freely a trigger L
having an upper somewhat lateral projection L' which can engage with a recess
o slot in the Duer spindle II and a lower lateral projection which can enter
a slot in the sleeve laud hook under the cup M which is fixed to the after flush
box. When the pull handle is in the down position as here shown, the trigger
parts L' and L' engage in both places thus firmly connecting the sleeve I with the
cup M and keeping the valve tightly olosed. But when the pull is raised the upper

page_text: part L is drawn out of its recess and the heavier lower part L' similarly from
under the cup M so that the trigger turns on its pin and when the pia has come to
the bottom of its slot H¹ the spindle H carries the sleeve I up with it and thus
raises the valve. The weight of the spindle is such as to normally keep the sleeve
locked and the valve closed
In cases where the closet is fitted near the water line, in addition to the valve
connected to the pull up handle above mentioned we sometimes fit a self acting
flap valve in the lower part of the closet, sccured in its place by wedges, spings or
other suitable means and so arranged that when the pull up valve is raised it will
prevent the inush of water from the sea from entering the closet pan, as the
self-acting valve will be closed against it, but will open automatically to allow
the contents of closet to pass away to the ship's side. Fig. 6 18 a vertical section
through a ship's closet fitted with such a flap valve N. The body Q of the closet
18 in this example of earthenware and the valve seating P 19 fixed in place by
means of two wedges O, one on each side, the metall.c valve seating P with the
valve N jointed thereto can be removed through the top of the body Q when the
upper valve S with the parts connected thereto and the flushing cistern R
have been removed The earthenware body Q is formed with a ledge Q' for the
Cistern R to rest on.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manue the same is to be performed we declare that what we
claim 18:
1. In ships' water closets, the application to the supply valve lifting spindle, of
an adjustable attachment for connection to its actuating tumbler lever for the
purpose of altering the amount of lift of the said valves according to the
varying distances of the closets from the source of water supply thus obviating
the use of separato regulating cocks substantially as described and shown.
2. In ships' water closets the application in connection with the pull up handle
attached to the discharge valve of a trigger or catch whereby the said valve is
held securely when on its soating but which is released when the handle is raised
substantially as described and shewn.
3. In ships' water closets with earthenware body and in conjunction, by preference,
with the trigger or catch device the application of a lower self-noting flap valvo
which is removable through the top of the body and will close of itself and prevent
the inrush of water from the sea when the pull up valve is raised but will open
automatically to allow the contents of the pan to pass out substantially as described
and shewn.
