page_text: I, JOHN SHANKS, of Tubal Foundry, 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 and action of
watercloset apparatus.
In carrying out my Invention the closet basin is made of what is known as the
"wash-out" kind, but with two distinct inlets for the water which is supplied from
a cistern. One of the water inlets is in the common position at the top of the
basin and is provided with a spreading fan, or is in communication with a hollow
rim, arranged to distribute the water round the basin. The other water inlet is in
a lower position facing the discharge outlet so that the force of the jet entering by
it is better directed for sweeping the contents of the basin into the discharge
outlet; and to give the fullest action to the jet the pipe or passage leading to this
lower inlet is made a direct continuation of the main downlet pipe from the cistern,
the upper inlet being supplied by a branch therefrom. The inlets with a portion
of the passages leading to them may be made in the samne piece with the basin and
so that there may be a single joint connecting them to the main downlet pipe; or
the downlet pipe may be made with branches to be separately connected to the
inlets. The cistern is of a size to contain the water for each flushing and is
emptied by means of a siphon. The downlet pipe is extended up through the
bottom of a well or depressed part formed in the bottom of the cistern, and the
open upper end of the downlet pipe is enclosed by a hood or inverted cup which
is fixed. The inverted cup extends down in the well or depressed part nearly to
the bottom, and between it and the sides of the well there is a loosely-fitting
annular plate or ring connected by rods to a lever at the top of the cistern. This
lever is connected to the closet handle so as when this handle is pulled up to
depress the ring this causing the water under the ring to rise up inside of the
inverted cup and start the siphonal action. .

page_text: Improvements in and Connected with Waterclosets.
I, JOHN SHANKS, of Tubal Foundry, 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 and action of
watercloset apparatus; and I hereunto append a sheet of explanatory drawings
showing such apparatus as made with my improvements.
In carrying out my Invention the closet basin, 6, is made of what is known as
the "wash-out" kind as shown in vertical section in figures, 1, and 2, of the
accompanying drawings, but with two distinct inlets, 7, 8, for the water which is
supplied from a cistern. One, 7, of the water inlets is in the common position at
the top of the basin, 6, and may either be provided with a spreading fan, or be in
communication, as shown, with a hollow rim, 9, arranged to distribute the water
round the basin. The other water inlet, 8, is in a lower position facing the
discharge outlet, 10, so that the force of the jet entering by it is better directed for
sweeping the contents of the basin, 6, into the discharge outlet; and to give the
fullest action to the jet the pipe or passage, 11, leading to this lower inlet, 8, is
made a direct continuation of the main downlet pipe, 12, from the cistern, the
upper inlet, 7, being supplied by a branch, 13, therefrom. The inlets, 7, 8, with a
portion of the passages, 13, 11, leading to them may be made in the same piece
with the basin, 6, as shown in figure, 1, and so that there may be a single joint
connecting them to the main downlet pipe; or the downlet pipe, 12, may be made
with or have connected to it a piece made with branches, 13, 11, as shown in
figure, 2, to be separately connected to the inlets, 7, 8. This improved arrange-
ment of the basin inlets, 7, 8, may have combined with it a simple arrangement of
the kind shown in figure, 1, for supplying a little water as an after service to insure
the filling of the bottom of the basin. This arrangement consists of a pocket or
small compartment, 14, having an opening at the top to receive water from the
upper inlet branch passage, 13, whilst there is at the bottom of the pocket a small
orifice leading into the basin. The pocket, 14, becomes more or less filled whilst
the water is descending but empties itself slowly because of the smallness of the
bottom orifice so that enough remains for the intended purpose after the main
supply has ended. This after-service arrangement is an adaptation to suit my
present improvements from substantially similar arrangements described in my
Patent Specification No 10416 of 1885.
The cistern to be used with my improved watercloset apparatus and also
applicable with various kinds of watercloset apparatus is shown as made according
to one modification in figure, 3, of the drawings, this figure being a vertical section.
The cistern, 15, is of a size to contain the water for each flushing and is emptied
by means of a siphon. The downlet pipe, 12, is extended up through the bottom
of a well or depressed part, 16, formed in the bottom of the cistern, 15; and the
open upper end of the downlet pipe, 12, is enclosed by a hood or long inverted
cup, 17, which is fixed. The inverted cup, 17, extends down into the well or

page_text: depressed part and has inlet openings made at the bottom of it; and between it
and the sides of the well there is a loosely fitting annular plate or ring, 18,
connected by a pair of rods, 19, to levers, 20, at the top of the cistern. In the
section figure, 3, only one of the rods, 19, and one of the levers, 20, are shown.
The levers, 20, are on a rocking shaft, 21, which has fast on it at one side of the
cistern a lever, 22, connected to the closet handle so as when this handle is
pulled up to cause the ring or plate, 18, to be depressed. This causes the water
under the ring or plate to rise up inside the inverted cup, 17, and start the
siphonal action.
The siphon details may be placed in the middle of the cistern, with the well, 16,
and plate, 18, in a complete circular form; or they may be arranged close to one
side of the cistern as shown in figure, 4, which is a horizontal section; and when
in the last described position the well, 16, and plate, 18, are not of a completely
circular form, whilst a single rod, 19, is used for moving the plate, 18.
Figure, 5, is a vertical section of my improved cistern apparatus with the siphon
details duplicated so as to provide for an after service. The water for the after
service is received in a separate compartment, 23, through a hole in the upper part
of the partition dividing it from the main compartment, and it is discharged
through a siphon pipe, 24, connected by a branch, 25, to the main downlet pipe, 12.
The inverted cup, 26, enclosing the siphon pipe, 24, is in this case made movable
and is connected to the end of a lever, 27, extending from the rocking shaft, 21,
oppositely from the levers, 20, connected to the plate, 18, of the main compartment,
so as to be raised when the plate, 18, is depressed, and vice versa. A small
valve, 28, is attached to the inside of the inverted cup, 26, to close the top of the
siphon pipe, 24, when the main siphon is started in order to prevent the sucking
action of the water passing down the downlet pipe, 12, from prematurely starting
the after-service siphon. When the closet handle is let go the inverted cup, 26,
descends and by a flange round its bottom causes the water below it to rise between
it and the siphon pipe, 24, so as to start the siphonal action.
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-The providing of a "wash-out" watercloset basin with two water inlets one
being at the top of the basin and the other near the bottom at the part opposite to
the main discharge outlet of the basin and supplied in a direct manner from the
downlet or service pipe, the parts being constructed with or without an after-
service pocket all substantially as herein before described and as shown in figures, 1,
and 2, of the accompanying drawings.
2-The arranging and combining together of the parts of siphonal cistern
water-supply apparatus for waterclosets substantially as hereinbefore described and
as shown in figures, 3, 4, and 5, of the accompanying drawings.
