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 of such
water closets as have double discharge valves and are suitable for ships' and other
structures in which such water closets may be required:
In a water closet made according to my present Invention, the basin, formed
preferably in the same piece of earthenware with a pedestal front, is partly of the
"washout" type, and has its discharge outlet at the back, the basin having a shallow
bottom concavity for retaining. water,. lower than the outlet: The basin outlet is
made with a nozzle projecting a short distance into a valve box fixed to the back of
the basin, and' to the outer end of the nozzle which is preferably inclined there is
applied a flap valve fixed to a horizontal spindle extending through a stuffing box
to the outside where a short lever is. fixed on it. In the lower part of the valve box
there is an outlet port. to which is applied.aisecond flap valve also fixed on a' spindle
extending, through. a. stuffing: box. and having a short lever fixed on its outer endi
The two valve spindles are preferably in the same vertical plane; and their levers
are jointed to a vertical bar to which vertical movement can be imparted by means
of the closet handle. The lifting, of the vertical har closes the lower valve and
opens the upper one and vice versa. The parts are arrangedi so that only a small
movement of the closet handle is required; and a tumbler. weight, or spring: may
be applied to insure a complete movement in either direction.

I, JOHN SHANKS, 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 has for its object to improve the construction of such
water-closets as have double discharge valves and are suitable for ships and other
structures in which such water closets may be required.
And in order that my said Invention and the manner of performing the same
[Price 8d.l

page_text: may be properly understood
hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing a water closet as made with my improvements.
Figure, 1, on the accompanying sheet of drawings, is a side elevation and
Figure, 2, is a vertical section showing my improved water closet.
In a water closet made according to my present Invention, the basin, A, formed,
preferably in the same piece of earthenware with a pedestal front, B, is partly of the
"washout " type, and has its discharge outlet, C, at the back, the basin, A, having
a shallow bottom concavity for retaining water, lower than the outlet, C. The
basin outlet, C, is made. with a nozzle, D, projecting a short distance into a
valve box, E, fixed to the back of the basin, A, and to the outer end of the nozzle, D,
which is preferably inclined there is applied a flap valve, F, fixed to a horizontal
spindle, G, extending through a stuffing box, H, to the outside where a short lever, J,
is fixed on it. In the lower part of the valve box, E, there is an outlet port, K, to
the underside of which is applied a second flap valve, L, also fixed on a spindle, M,
extending through a stuffing box, N, and having a short lever, P, fixed on its
outer end. The two valve levers, J, P, are jointed to a vertical bar, Q, which is
connected by a cross bar R, to a rod, S, working in a guide tube, T, and on which
the closet handle, U, is fixed. On pulling up the closet handle, U,
vertical movement is imparted to the vertical bar, Q, which then through
the levers, J, P, closes the lower valve, L, and opens the upper one, F, and
vice versa. A second lever, V, on the horizontal spindle, G, is connected
through links, W, with the spindle, X, of the water-inlet valve, so that on
the closet handle, U, being pulled up to actuate the valves, F, L, as herein before
described, the water is also admitted to the closet. The parts are arranged so that
only a small movement of the closet handle is required.
"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 a water closet with a valve box at the back of the basin arranging a nozzle on
the basin outlet to which a flap valve is applied; and forming in the lower part of
the valve box an outlet port to which a second flap valve is applied both valves being
on horizontal spindles. on the outer ends of which are levers jointed to a vertical bar
to which movement can be imparted by the closet handle; substantially as and for
the purposes hereinbefore described, and as shown in the accompanying drawings.
