page_text: I, EDWIN JAMES PRESTON, of the Firm of J. Stone and Company, of Deptford,
in the County of Kent, Engineers, do hereby declare the nature of this invention
to be as follows:-
My invention relates to ships' closets and particularly to such as are mounted
below the water line of the ship or other vessel.
According to my invention I provide a pan or basin mounted on a suitable
frame which basin is in communication with a pipe for the supply of water for
Hushing purposes and has a valve arranged in a valve casing between the water
supply and the basin. This valve is suitably operated by a lever in the follow-
ing manner: The valve is loosely connected to a valve rod or stem which moves
in guides so that the valve may always seat itself properly even if its stem should
be out of truth and there is a lever working on a pivot and connected to the
valve rod. The baudle for operating the aforesaid lever is preferably arranged to
pull up vertically and at the end of its rod is a weight which is loosely connected
to the rod and to the lever or it may be connected to the lever only. This weight
is for the purpose of effecting the closing of the valve, but the arrangement of the
handle provides for a lost motion so that it is impossible to force the valve on
to its seat by operating the handle.
In connection with the closet busin there is a pump, preferably double acting,
aud operated by a lever pivotted to the frame of the closet At each end of the
pump there is a suction valve communicating with the discharge opening of the
closet basin which valve is mounted in such manner as to be horizontal when
Reated or at all events it is so weighted as to be normally closed whatever may
be the angle of the vessel's deck when riding over the waves or when rolling or
careening. Similarly there is at each end of the pump a delivery valve also
mounted so as to be seated when horizontal and the delivery valves communicate
by a common passage to the discharge pipe leading outside of the ship. The
valve seats for each set, consisting of a suction valve and a delivery valve, are
fixed to or in one with an end cover for the pump, it being understood that the
piston rod of the pump passes through a stuffing box or the like in one end cover.
Heretofore it has been usual in closets of this description to mount the four
valves on separate covers but by my invention I am enabled to reduce the number
of joints by two, while at the same time permitting of easy access to and cleansing
of the interior of the pump, passages and valves. A further advantage consists
in arranging the valves to seat themselves in a horizontal position whereby they
are not so liable to be swung off their seats as has been the case previously where
the valve seats have been at an angle of 45° or thereabouts to the ship's deck
and finally by loosely connecting the Hushing valve to its rod or siem and by
rendering the closure of the flushing valve independent of the flushing handle,

more effective in use.

I, EDWIN JAMES PRESTON, of the Firm of J. Stone & Company, of Deptford,
in the County of Kent, Engineers, 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:
My invention relates to ships' closets and particularly to such as are mounted
below the water line of the ship or other vessel.
Figure 1 of the accompanying drawings represents in side elevation a closet
constructed according to my invention.
Figure 2 is a section thereof.
Figure 3 is a plan and
Figure 4 is a vertical section on the line X-Y Figure 3.
According to my invention I provide a pan or basin A as shown in the drawings
which basin is in communication with a pipe B for the supply of water for flush-
ing purposes and has a valve C (Figures 3 and 4) arranged in a vulve casing D
between the water supply and the basin. This valve is suitably operated by a
levor in the following manner;-The valve C Figure 4 is loosely connected to a
valve rod or stem for instance by a sot screw taking into a groove in the valve
rod as shown (which valve rod moves in guides or as shown in a stuffing box G)
so that the valve C may always seat itself properly even if its stem should be out of
truth and there is a lever E working on a pivot H and connected by a link as
shown to the valve rod F. The handle I for operating the lever E is preferably
arranged to pull up vertically and at the end of its rod is a weight K which may
be loosely connected to the rod and to the lever or as shown for example it is
pivotted to the lever and loosely connected to the rod of the handle. This
weight K is for the purpose of effecting the closing of the valve C, but the
arrangement of the connection between the handle rod provides for a lost motion
so that it is impossible to force the valve on to its seat by operating the handle.
In connection with the closet basin A there is a pump L, preferably double acting
of which the piston M (Figure 4) is double acting and operated by a lever N
pivotted to the frame 0 of the closet by means of connections such as the con-
necting rod P and bell crank lever Q. At each end of the pump there is a suction
valve marked respectively R and R' communicating with the discharge opening S
of the closet basin which valves R and R' are mounted in such manner as to be
horizontal when seated or at all events they should be so weighted as to be nor-
mally closed whatever may be the angle of the vessel's deck when riding over
the waves or when rolling or careening. Similarly there is at each end of the
pump a delivery valve marked respectively T and T which valves are also
mounted so as to be seated when horizontal and these valves communicate by a
common passage to the discharge pipe U leading to the outside of the vessel.
The valve seats for each set consisting of a suction valve and a delivery valve are
fixed to or in one with an end cover for the pump which end covers are marked
respectively V and V and the latter is provided as shown with a stuffing box W
Figs. 1 and 4 or the like for the piston rod. Z is an overflow pipe.

page_text: Heretofore it has been usual in closets of this description to mount the four
valves or separate covers but by my invention I am enabied to reduce the number
ot joints by two while at the same time permitting of easy access to and cleansing
of the interior of the pump. A further advantage consists in arranging the valves
to seat themselves in a horizontal position whereby they are not so able to be
swung off their seats as has been the case previously where the valve seats have
been at an angle of 45° or thereabouts to the ship's deck and finally by loosely
connecting the flushing valve to its rod or stem and by rendering the closure of
the flushing valve independent of the flushing handle the wear and tear on the
valve is much reduced and the valve is consequently more effective in use.
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;-
_
1. The combination of parts forming the improved construction of ships closets
substantially as described and shown.
2. A ships closet provided with a basin, a double acting pump, a set of suction
and delivery valves mounted horizontally in one cover at each end of the pump,
means for communicating motion to the piston of the pump, and means for flush-
ing the basin substantially as described and shown.
3. A ship's closet provided with a basin, a double acting pump a set of suction
and delivery valves mounted horizontally in one cover at each end of the pump,
a hand lever, means for communicating motion from the hand lever to the pistou
of the pump a flushing valve, a handle for opening auid flushing valve, a weight
for causing said flushing valve to be seated and a lost motion between the handle
and the valve substantially as described and shown.
