PROVISIONAL SPECIFICATION.
Improvements in Ships' Waterclosets.
I, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of
Renfrew, North Britain, Sanitary Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention relates to under-water-line ships' waterclosets constructed
entirely above the floor line and has for its object to improve the construction of
the watercloset and the pump or discharge apparatus so as to render them more!
effective and satisfactory in use and so that the entire watercloset pump, and
accessory parts may be disconnected and removed for examination, repair, or
renewal without interfering with the discharge pipe also so as to prevent the sea
water entering the ship when the parts are so disconnected.
In carrying out my invention the basin, which may be of fireclay, earthenware,
or metal, is of the wash-down type having the outlet at the back, or centre, or
other convenicut place, and is supported on a pedestal which may be made in a
piece with the basin or separate therefrom. The water-supply horn to which the
water is led from the cistein, tank, or other supply apparatus, communicates with
the rim of the basin which may be made either perforated, open, or with a fan for
directing the flushing and cleansing water towards the outlet of the basin. This
outlet communicates through a check valve with a pump so constructed that
obstruction is reduced to a minimum, the top or crown of the barrel being rounded
to enable the bridge of the pump over the bucket to be made large enough to
allow the valve to work with perfect freedom. The discharge pipe is connected
by a flanged or other suitable joint to the crown or other convenient part of the
pump and at the connection there is fitted a check valve which admits of the
entire watercloset pump, and other parts being disconnected and removed for.
examination, repair, or renewal without interfering with the discharge pipe, this
valve preventing the sea water from entering the ship when the parts are so
disconnected.
The levers for actuating the pump may be arranged in any convenient way to
suit the available space.

Improvements in Ships' Waterclosets.
1, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of
Renfrew, North Britain, Sanitary 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, that is to say :—
My said invention relates to under-water-line ships' waterclosets constructed
entirely above the floor line and has for its object to improve the construction of

page_text: effective and satisfactory in use and so that the entire watercloset pump, and
accessory parts may be disconnected' and removel for examination, repair, or
renewal without interfering with the discharge pipe, also so as to prevent the sea
water entering the ship when the parts are so disconnected.
In carrying out my invention I cause the basin outlet to communicate through
a check valve, with a pump the top or crown of which is made rounded to enable
the bucket bridge to be made large enough to allow the valve to work freely.
The discharge pipe is connected to the pump crown and is fitted with a check
valve to keep out the sea water and so allow of the pump parts being disconnectel
for examination and repair when required.. The invention also comprises an
improved combination and arrangement of the parts of a ship's watercloset.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing ship's waterclosets as made with my
improvements.
Figures, 1, 2, and 3, of the drawings are side, front, and back elevations
respectively:
Figures, 4, and 15, are vertical sections as at right angles to each other.
Eigure, 6, is a back elevation of a second modification.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
The watercloset basin, A, which may be made of fireclay; earthenware, or metal
is of the wash-down type having the outlet, B, at the back (or it might be at the
centre or other convenient place) and is supported on a pedestal; C, which is made
in a piece with the basin (or it might be separate therefrom). The water-supply
horn communicates with the rim, D, of the basin which may be made either
perforated, open, or with a fan for directing the flushing and cleansing water
towards the outlet, B, of the basin. This outlet, B, communicates through a
foot-check valve, E, with a pump, G, so constructed that obstruction is reduced
to a minimum, the top or crown, H, of the barrel being rounded to enable the
bridge, J, of the pump:bucket, K, to be made large enough to allow the valve, L,
to work with perfect freedom. The discharge pipe, M, is connected by a flanged
or it might be any other suitable joint to the crown, H, (or other convenient part)
of the pump, G; and in the discharge pipe, M, at the joint there is screwed a
flanged ring, F, to which a delivery check valve, N, is fitted. The valve, N; by.
stopping the ingress of sea water. admits of the entire watercloset, pump and other
parts being disconnected and. removed for examination, repair, and renewal without
interfering with the discharge pipe, M.
The closet lever, P, is arranged at the side of the basin, A; and is fixed on a
horizontal spindle, Q, carried at the back of the apparatus on a bracket, R, fixed
to the pump barrel and the closet basin, the spindle also having, on it, an arm, S,
connected to the pump, bucket rod, T.
The pump bucket, K, when moved by the closet lever, P, draws the contents of
the basin, A, through the foot valve, E, and on further actions of the lever
taking place forces them through the delivery valve, N, and the discharge
pipe, M.
•
A pump, U, and parts, comected therewith similar to the pump, G, and its
driving and other parts are provided for flushing the basin, A, with clean water
the pump delivery pipe-being connected. to the water-supply horn, and the suction
pipe directly to a pipe communicating with the. sea or a tank. The pump,
worked by an independent lever; V:
U, is
Instead of the flushing water being supplied by means of a pump (U) it may be
supplied from any source yielding a sufficient head, its ingress being controlled
by a valve, W, (shown in Figure, 6) operated by an arm or lever, X, on the
spindle, Q, which is extended to carry it; a second lever (V) being dispensed
with.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination and arrangement of parts constituting the improved ship's.
watercloset substantially as herein before described.
2. In a ship's watercloset, placing between the basin outlet and the discharge
pipe, a single-acting pump having a rounded crown, a foot valve, a bucket with a
central valve, and a delivery check valve which remains attached to the discharge.
pipe when the pump is disconnected therefrom substantially as.and for the purposes-
herein before described.
