I, JOHN SHANKS, 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 has for its object to improve the construction or combina-
tion of parts of watercloset apparatus so as to adapt them for ships the improve-
ments or some of them being also applicable otherwise.
In carrying out my invention in the case of a series of waterclosets in separate
compartments I have a bottom pipe or channel piece extending through the
series of compartments, and made preferably with a flat top. The closet basins
are made each with a trap-bend discharge with a flanged end to be bolted or
otherwise fixed to the pipe top. The inlet for the flushing water is fitted with a
valve in the form of a heavy plunger working through a stuffing box and closing
by its weight down against the pressure, being raised by means of a cord or lever;
or the heavy piece may be connected by a rod to the valve. The cord may be
connected to the door of the compartment so as to be pulled by the opening of
the door.
In order to supply after flush and to maintain a suitable quantity of water in
the basin notwithstanding the withdrawal of water from the trap bend through
motions of the ship or or actions of the sea or otherwise, I provide in con-
nection with each basin a compartment having in it a float to which is fixed or
connected a valve controlling a branch water supply. The compartment being
in communication with the closet basin, the water in both falls or rises simul-
taneously and the valve opens when required.
The valve controlled by the float may be the main water-supply valve, and
may be connected to the closet handle or lever, so as to be opened thereby for
the main flush.
To prevent backward flow through the discharge passage, one or two cheek
flap valves may be arranged in that passage.
The valve controlled by the float when the float is on the end of a lever com-
prises a plunger closing against the pressure and acted on by a small downwardly
extending lever having its bottom end jointed to the float lever. The float lever
extends beyond the joint and is jointed to a toggle link jointed to a part of the
valve box, forming a toggle arrangement such that when the float lever is raised
into a horizontal position the joints of the float lever and link are in or nearly in
a horizontal position, and the combination effectually prevents the opening of
the valve by the water pressure.

page_text: 1, JOHN SHANKS, of Tubal Works, Bari head, 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 has for its object to improve the construction or combina-
tion of parts of watercloset apparatus so as to adapt them for ships, the improve-
ments or some of them being also applicable otherwise.
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 in describing my improvements.
Figure 1, on the accompanying sheet of drawings is a front elevation partly in
section of one modification of my improvements Figure 2, is a sectional plan
and Figures 3, and 4, are respectively side and front elevations partly in section
of a second modification. Figures 5, and 6, are vertical sections of two modifica-
tions of my improvements applicable for ships' waterclosets; and Figures 7,
and 8, are respectively a section and an elevation of a water-supply valve. In
these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
In carrying out my invention in the case of a series of waterclosets in separate
compartments as shown in Figures 1, to 4, I have a bottom pipe or channel
piece, A, extending through the scries of compartments and made preferably
with a flat top. This pipe, A, may be either continuously or intermittently
flushed by water led to it by a pipe, B. The closet basins, C, are made each
with a trap bend discharge with a flanged end, D, to be bolted or otherwise fixed
to the pipe top as shown in Figure, 1. Or the trap bend discharge of each
closet basin, C, may, as shown in Figure 3, be fixed to an enlargement, A 1, in
the pipe, A, which pipe, A, in this modification is shown (Figure, 4) as being
made in sections with flanges, E, to permit of the sections being bolted together
to form a continuous pipe or channel.
The inlet, F, for the flushing water is fitted with a valve in the form of a
heavy plunger, G, (Figure, 1) working through a stuffing box, H, and closing
by its weight down against the pressure being raised by means of a cord, J,
which may be connected to the door, K, of the compartment so as to be pulled
by the opening of the door. Or the heavy plunger, G, may, as shown in
Figure,, be raised by means of a lever, L. The heavy plunger, G, may be made
up of a number of separate pieces as shown in Figures, 4, and 6, so that the
weight can be adjusted to suit the pressure against which it has to act.
heavy piece, G, is connected by a rod, M, to a valve, N. This arrangement of
The
valve is applicable for use in connection with other forms of closet basins.
In order to supply after flush and to maintain a suitable quantity of water in
the basin, C, notwithstanding the withdrawal of water from the trap bend
through motions of the ship or actions of the sea or otherwise I provide in con-
nection with each basin, C, a compartment, P, which may be either separate
from the basin as shown in Figure, 5, or made in a piece with the basin as shown
in Figure, 6, The compartment, P, has in it a float Q, to which is fixed or
connected a valve, R, admitting water from the main inlet, F, (Figure, 5) or
from a branch water supply pipe, S (Figure 6). The compartment, P, is in com-
munication with the closet basin, C, either through a passage, T, as shown in
Figure, 5, or through a small hole, U, in the back of the basin, so that the water

page_text: in both falls or rises simultaneously and the valve, R, opens when required. To
prevent backward How through the discharge passage, cheek flap valves, V, may
be arranged in that passage.
An improved water supply valve controlled by a float on the end of a lever, W,
such as is partly shown in Figures, 7, and 8, comprises a plunger, X, closing
against the pressure and acted on by a small downwardly extending lever, Y,
having its bottom end jointed to the float lever, W. The float lever extends
beyond the joint and is jointed to a toggle link, Z, jointed to the valve box, l',
forming a toggle arrangement such that when the float lever, W, is raised into a
horizontal position the joints of the float lever and link, Z, are in or nearly in
a horizontal position. A heel, I, on the toggle link, Z, when the parts are in the
horizontal position encounters the part, r, and prevents the float lever, W,
from being raised above that position and the combination effectually prevents
the opening of the valve, X, by the water pressure. This float valve mechanism
is applicable to various kinds of cisterns for supplying waterclosets.
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. In connection with a series of water-closets providing a bottom pipe or
channel piece made with a flat top, the closet basins being each made with a
trap-bend discharge and being fixed to the pipe top substantially as hereinbefore
described with reference to Figures, 1, to 4, of the accompanying drawings.
2. In connection with water-closets fitting the inlet for the flushing water
with a valve in the form of or attached to a heavy plunger, the valve closing by
its weight down against the pressure and being raised by means of a cord or
lever, substantially as herein before described with reference to Figures, 1 to 6,
of the accompanying drawings.
3. In connection. with ships water-closets providing in connection with each
basin a compartment having in it a float controlling a supplementary water
supply valve, the compartment being in communication with the closet basin
substantially as and for the purposes hereinbefore described.
4. In float valve water-supply mechanism, a valve closing against the pressure
and acted on by a small downwardly extending lever jointed to the float lever
the float lever extending beyond the joint and being jointed to a toggle link
jointed to a part of the valve box substantially as and for the purposes herein-
before described.
