IMPROVEMENTS IN WATER CLOSETS to be as follows:-
Year: 1884

PRESTON trading as J Stone & Co at Deptford in the County of Kent, Engineers,
and EDWIN WILLIAM DE RUSETI of 2 Fell Road, Croydon, Civil Engineer do
hereby declare the nature of said invention for "IMPROVEMENTS IN WATER
CLOSETS to be as follows:-
"
We provide in the upper part of the closet a water supply cistern for giving an
after flush. This cistern has two apertures at the top, one for the inlet of water
from the source of supply and the other for the outlet of water to the closet basin
for the main flush. It has also a small aperture at the bottom for giving an after
flush after the connection to the supply is closed.
We produce this flush and after flush through the motion of the pull handle, by
a connection either with a water waste preventing valve or with a supply valve
arranged on the closet such for instance as the supply valve mentioned in the
Specification of our previous patent No 5380 of 1882.
The two closet valves mentioned in that Specification we arrange and operate in
our improved manner viz so that ono valve is always closed before the other
commences to open thus preventing the rising of any effluvia or wash from the
sea (as applied to ship's purposes). The upper valve is arranged vertically or
nearly so,
and the lower valve at an angle. These valves are actuated by a straight
pull rod provided with two friction rollers which work in tumblers or cam groove
levers on the valve spindles.
The closet pan is by preference of an oval form and has a side outlet being fixed
laterally to the body of the closet and also holding the seating for the upper
valve. The body of the closet is attached at an angle to the lower outlet casting
and also holds the seating for the bottom valve. Both the closet valves are thus
readily removable when required without disturbing the attachment of the closet
to the ships deck or other floor.
In order further to afford ready access to the valves for clearing them we may
provide the aforesaid supply cistern with a removable top and bottom lid which
may be fixed by the same through bolt and nuts.
In some cases for a cheaper class of closets the lower valve with the parts for
working it may be omitted."
Sometimes we make the supply cistern with a passage down through for the
pull rod which we connect to the stem of the closet valve and provide the latter
with a passage fitted with an overflow valve which is self closing for preventing the
escape of noxious gas.

PRESTON trading as J. Stone & Co at Deptford in the County of Kent Engineers
and EDWIN WILLIAM DE RUSETT of 2 Fell Road Croydon Civil Engineer do
hereby declare the nature of said invention for "IMPROVEMENTS IN WATER
CLOSETS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-—
"
We will describe these improvements with reference to the accompanying
drawings of which Figure 1 is a vertical section through a water closet with two
valves and with a water supply cistern arranged for a flush and an after Blush
Figure 2 is a side elevation showing the means for working the said two valves
and the supply valve from the pull handle.
A is a water supply cistern arranged in the upper part of the closet and serving
to give the aforesaid flush and after flush to the basin B. The cistern A has two
apertures at the top, one at A¹ for the inlet of the water from the source of supply,
that is to say in this case by means of the supply valve C, and the other aperture
at A2 for the outlet of water to the closet basin B for the main flush. It has also
a small aperture A³ at the bottom for giving an after flush after the connection to
the supply valve C is closed, We produce this flush and after flush through the
motion of the pull handle D and rod D¹ by suitable connection either with a water
waste preventing valve or with a supply valve arranged on the closet such for
instance as the supply valve C which is mentioned with reference to Figures 10
to 18 of the Specification of Patent N° 5380 of 1882. This valve C is here
shown connected by its spindle C¹ to a lever C² which is jointed to the pull
rod D¹.
The two closet valves mentioned in that Specification we arrange and operate
in an improved manner viz: so that one valve is always closed before the other
commences to open thus preventing the rising of any effluvia (or wash from tbe
sea, applied to ships purposes) The upper valve E is arranged vertically or nearly
50, and the lower valve F at an angle. These valves E and F are actuated by the
straight pull rod D' which is provided with two friction rollers G and H respec-
tively. The roller G works in a tumbler or cam groove lever G₁ fixed on the
spindle E of the valve E and the roller H works in a tumbler H¹ fixed on
the spindle F of the valve F. The valves proper E and F are by preference
mounted on joint or hinge pins E2 and F2 so as to be able to turn slightly
thereon and more readily and accurately find their place on their seating E' and F
respectively.
The closet pan B is by preference of an oval form and has a side outlet at the
upper valve E, being fixed laterally to the body of the closet and also there holding
the seating E for the said upper valve. The body I of the closet is attached at
an angle to the lower outlet casting K and also holds the seating F³ for the
bottom valve F. Both the closet valves E and F are thus readily removable
when required without disturbing the attachment of the closet to the ship's deck

page_text: or other floor. S is an overflow passage and S¹ a valve for relieving any undue
pressure that might be produced in the Chamber between the two valves E and F
by the sudden closing of the lower valve F, but we do not claim as new this
passage S and valve S¹.
In order further to afford ready access to the valves E and F for clearing them
we may provide the aforesaid supply cistern A with removable top and bottom
lids L and M which may be fixed by the T bolts L' and M' (or by the same
through bolt) and nuts.
Figure 3 is a side view of a closet of very similar internal construction, but
where the body I of the closet is made with a lower part I' to which the upper
part is bolted and which contains the lower closet valves F. The parts for
actuating the valves are also arranged somewhat differently the pull rod D¹ being
jointed to the lever N the other end of which by slot and pin is connected to the
lever O on the fulcrum spindle O¹. To the lover O is jointed the rod P which by
lever C actuates the spindle C¹ of the supply valve C. On the fulcrum spindle O'
are also fixed the levers Q and R which work in the cam groove levers or tumblers G
and H respectively on the spindles of the upper and lower closet valves E and F as
in Figures 1 and 2.
In some cases for a cheaper class of closets the lower valve with the parts for
working it may be omitted. Figure 4 is a side elevation and Figure 5 a vertical
section through such a form of closet, fitted only with an upper valve E. The
mode of actuating this valve E and the supply valve C from the pull rod D¹ is
similar to that shown at Figure 2. In Figure 6 we have shown a modified
arrangement of working gear to adapt it to the altered position of the valve C
which in this case is connected to the back instead of to the side of the supply
cistern A.
Sometimes we make the supply cistern A with a passage down through for the
pull rod D¹. Figure 7 is a sectional side elevation and Figure 8 plan section of
such an arrangement. The pull rod D¹ passes down through a passage A× formed
in the supply cistern A and at its lower end connected to the stem of the closet
valve E and provide the latter with a passage S fitted with an overflow valve St
which is self-closing for preventing the escape of noxious gases. The ball valve S¹
plays in a trap or trough S* but we do not claim as new this particular trap
valve E. The pull rod D₁ is by means of the block T fixed thereon which block T
also serves as a weight and by means of the double armed fork lever T¹ jointed to
the block T connected with some suitable part for actuating a supply valve.
Figure 9 is a transverse sectional elevation of such an arrangement where the
double armed fork lever T¹ by a rod or link P is connected to the lever C' for
actuating the spindle C₁ of the supply valve C on the cistern A of the closet,
similarly to the arrangement shown at Figure 3.
Figure 10 is a transverse sectional elevation of a similar arrangement but where
the lever T¹ is connected to a chain P the other end of which is connected to a
lever C the other end of which is connected to the spindle C₁ of an ordinary
overhead supply or water waste preventing cistern U which is automatically
charged by means of ball cock.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed We declare that what
We claim is
First: The construction of closet water supply cistern A and also the mode of
and means for causing it to give first a flush and then an after flush after the
connection to the supply valve is closed substantially as described with reference
to the drawings.
Second-The improved arrangement of upper and lower water closet valves
or upper valve alone and also the mode of and means for actuating such valve

page_text: or valves and the water supply valve substantially as described with reference to
the drawings.
Third The combinations of parts forming the improved constructions of double
and single valve water closets substantially as described with reference to the
drawings.
