Improvements in Snips water Closets.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford, in the
County of Kent, Engineers and RICHARD HESSLEWOOD, in the employ of the
said firm, do hereby declare the nature of this invention to be as follows:-
This invention is applicable to ships' water closets fitted above and below the
water-line.
We do away with the usual enclosing wood casing and leave all the working
mechanism open for inspection and repair but out of sight. The pan is made of
earthenware for the sake of cleanliness and good appearance and is made with a
vertical front forming a shield in front of the principal working parts; the outlet
is at the front, and is made to slant down towards the back. The pan is longer
from front to back than the width across, thus enabling the closet to be used as a
urinal when the cover is lifted. The supply valve for flushing is at the back and
is worked by a pull-up handle with weighted lever gear, the water pressure also
tending to keep it normally closed.
The working parts are so arranged and constructed as to make them easy to
work and quick in action. By these improvements the closets are rendered
especially suitable for first class passenger steamers, yachts and the like.
In closets fitted above the water-line and with single or double valves, the latter
as well as the supply valve are worked from the pull-up handle by a weighted foot
piece connected to the lower end of the bandle rod and jointed near one end of a
lever which by slot cam or tumbler operates the closet outlet valve (or a slot cam
for each valve in case of a double valve closet) and has its fulcrum at one side of
the near the front of same. A back continuation of this lever comes against the
supply valve spindle and opens its valve when the pull-up handle is raised. The
overflow is formed at the side of the after-flush cistern and is trapped at its lower
end which leads into the closet valve box. The said cistern is on the top of the
valve box and connected therewith.
In closets fixed below the water-line we employ a horizontal double acting soil
pump which is placed at the back of the closet and is worked from an upright lever
by means of suitable lever, cam, tooth sector or other connections. In one arrange-
ment the lever has its fulcrum at a floor plate and is from a point a few inches
above it by a link connected to one arm of a bell crank lever, the other arm being
by a short link connected to the pump rod. The lower end of the weighted pull-up
handle is jointed to a lever which operates the supply valve. The pump is fitted
with doors for easy access to the valves.

COMPLETE SPECIFICATION.
Improvements in Ships' Water Closets.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford, in the
County of Kent, Engineers and RICHARD HESSLEWOOD in the employ of the
said firm, do bereby declare the nature of this invention and in what manner
Price 8d.l

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement :-
This invention is applicable to ships' water closets fitted above and below the
water line.
We do away with the usual enclosing wood casing and leave all the working
mechanism open for inspection and repair but practically out of sight. The pan is
by preference made of earthenware for the sake of cleanliness and good appearance
and is made with a vertical front forming a shield in front of the principal working
parts; the outlet is at the front and is made to slant down towards the back. The
pan is sensibly longer from front to back than the width across, thus enabling the
closet to be used as a urinal when the cover is lifted. The supply valve is at
the back and is worked by a pull-up handle with weighted lever gear, the water
pressure also tending to keep it normally closed. The working parts are so arranged
and constructed as to make them easy to work and quick in action. By these
improvements all as hereinafter described the closets are rendered especially
suitable for first class passenger steamers, yachts and the like.
Fig. 1 of the accompanying drawings is a side view, Fig. 2 a sectional side view
and Fig. 3 a back view of a single valve ship's water closet fitted above the
water line.
The pan A is made with a vertical front forming a shield in front of the principal
working parts; the pan is sensibly larger than the width across; the outlet A¹
slants from the front towards the back; B is the valve to the valve box C and
soil pipe. The supply valve D is arranged at the back and is together with the
closet valve B worked from the pull-up handle rod E. The lower end of the latter
is for this purpose connected to a weighted foot piece F which is jointed to a lateral
boss G on the lever G near the back end of same, the lever fulcrum being at one
side of the pan near the front of same. A back continuation G' of this lever comes
in contact with the lever H which operates the spindle H' of the supply valve and
opens the latter when the pull-up handle is raised. The weight H2 serves to close
the supply valve when the pull-up handle is let go. The closet valve B is operated
from the lever G by the slot cam or tumbler I. The overflow A' is formed at the
side of the after-flush cistern K and is tapped at its lower end A which leads into
the closet valve box C. The said cistern K is at the top of the valve box C and
connected therewith.
Fig. 4 is a side elevation, Fig. 5 a sectional side view and Fig. 6 a back view of
a double valve ship's water closet fitted above the water line. The general
arrangement of parts is similar to the single valve closet described except as to
there being two closet valves B and L worked from the lever G by slot cams I
and 1'; also instead of the trapped overflow the overflow A² is fitted with non-
return valve A³ to the lower valve box and soil pipe M.
Fig. 7 is a sectional side view, Fig. 8 a back view and Fig. 9 a part sectional
plan view of a ship's water closet fixed below the water-line and provided with a
double acting soil pump which latter is shown separately in the vertical sectional
side view Fig. 10.
The outlet A from the pan A is connected to the suction valve chamber N of
the horizontal double acting pump, the barrel O of which is placed transversely at
the back of the closet pan and is worked from an upright lever P by means of
suitable lever, cam, tooth sector or other connections. In the example here shown
the lever P has its fulcrum on a floor plate Q upon which the pump and closet are
mounted and is from a point a few inches above it by a link P¹ connected to one
arm of a bell-crank lever P2, the end of the other arm working in a slot head O'
on the pump rod 01. The lower end of the weighted pull-up handle R is jointed
to a lever S, which operates the supply valve spindle S. The pump is fitted
with doors for easy access to the valves. The suction valves T, Fig. 7, are
each jointed to a removable door T' which is fixed in place by two screws T2,
Figs. 7 and 9. The delivery valves U are jointed to the removable door Uí
which is fixed in place by the screws U³.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A single valve ships' water closet fitted above the water line in which the
soil outlet is arranged to slant down from the earthenware or other suitable pan
towards the back thereof where the after-flush cistern is arranged having a trapped
overflow passage to the closet valve box, the supply valve arranged at the back of
the said cistern being actuated by a pull handle at the rear and a weighted lever at
the side which lever also works the closet valve substantially as described with
reference to Figs. 1, 2 and 3.
2. A double ship's water closet fitted above the water line in which the soil
outlet is arranged to slant down from the earthenware or other suitable pan towards
the back thereof where the after-flush cistern is arranged having an overflow com-
municating with the lower valve box by a passage provided with non-return valve,
the supply valve arranged at the back of the said cistern being actuated by a pull
handle at the rear and a weighted lever at the side which lever also works the
closet valves substantially as described with reference to Figs. 4, 5 and 6.
3. A ship's water closet fitted below the water line in which the soil outlet is
arranged to slant down from the earthenware or other suitable pan to the suction
chamber of a horizontal double acting pump arranged trausversely at the back and
operated by suitable connections from a lateral lever handle, the supply valve
arranged at the rear being actuated by a weighted pull handle at the side
substantially as described with reference to Figs. 7, 8, 9 and 10.
