PROVISIONAL SPECIFICATION.
Improvements in Waterclosets and in Apparatus connected
therewith.
We, SIDNEY JENNINGS and JOHN MORLEY, both of Palace Wharf, Stangate,
Lambeth, in the County of Surrey. Sanitary Engineers, do hereby declare the
nature of this invention to be as follows:-
:-
The watercloset is of the pedestal type and is provided with a flushing cistern
(very similar to that described in the Specification No. 407 of the year 1886)
divided into three compartments each provided with a valve, whose rods are
connected with levers acted upon by a tappet axis caused to rotate by the pull.
When the axis is turned the tappets first permit the valves in the ball valve and
after flush compartments to drop to their seats so that no more water can pass into
the main flushing compartment of the apparatus, and the afterflow compartment is
ready to retain water within it. Immediately afterwards the movement of the axis
causes the main flushing valve to be opened and water rushes rapidly out of the
main compartment. Some of the water passes down by the passage through the
after flow valve, and this forms the main flushing supply whilst the remainder of
the water missing this passage is retained in the after flow compartment.
On the pull being released the axis returns to its original position, the after flow
valve then lifts allowing the after flow water to pass away, so that the after flow
water enters the pan after the pan valve has closed and it there remains.
The pan valve is opened and closed by the revolution of the same axis being
timed to open before the main flush enters the pan and to close again before the
after flush.
The stem of the pan valve passes out of a tube in the top of a cover or cap
closing in the back of the pan and its upper end is connected by links to opposite
sides of a ring encircling the stem and forming part of a lever having one end
pivotted to the cover whilst its other end is pivotted to a rod connecting it to a
lever operated by a tappet on the pull axis.
The overflow from the pan is arranged as follows:-The cover at the back of
the pan is provided with a dome (or domes) having a vertical partition running
nearly but not quite to its top the dome being open on one side of the partition to
the pan and on the other to the overflow so that the surplus water passes over the
partition and down the overflow. At the top of the dome there is a valve opening
inwards which prevents water or air from escaping but allows air to enter and so
obviates any risk of a rush of water down the overflow syphoning out the contents
of the pan.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section and Figure 2 a front elevation of a closet con-
structed according to this invention. The flushing cistern at the upper part of
these figures differs only in shape from that described in our prior Specification
No. 407 of the year 1886 and requires no further description.
a is a rod which is lifted by the revolution of the tappet axis before the main
flush enters the pan and is lowered again before the after flush. The bottom of
the rod a is connected by a link b to the lever c. The link is formed of a tube and
screw so that its length can be readily adjusted. Part of the lever c consists of a
ring to which are pivotted the links d by which the lever is connected to a
vertical rod e passing through the ring c¹ and down through a tube f¹ carried by
the cover or cap which closes the back of the pan. These parts are shown to a
larger scale in plan, side elevation and transverse section respectively at Figures 3
4 and 5. The other end of the lever c is pivotted at 2 to an upright fixed to the
cover f. Fixed to the lower end of the rod e is a portion of a sphere e¹ upon which
works a spherical socket 9 screwed onto the top of the valve h. This enables the
valve to adjust itself in its seat notwithstanding any slight eccentricity of ring h¹
forming its face.
g
The cover is provided with two domes kk each having an air inlet valve at
the top. Each valve consists of a disc of indiarubber k¹ as shown. Il are partitions
running from front to back of the domes and forming weirs over which any surplus
water from the pan flows, the compartments k² k² of the domes being in connection
with the pan and the compartments k³ ³ with the overflow pipe.
The flushing cistern referred to above may be replaced by other flushing
apparatus producing like results.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The combination of a flushing apparatus, a pau, an outlet valve from the pan
and mechanism for opening the valve before the main flush enters the pan and for
closing it again before the after flush substantially as described.
2. The combination of cover or cap closing the back of the pan, a tube carried
by the cover or cap, a stem passing through the tube and a pan valve carried and
actuated by the stem substantially as described.
3. The overflow consisting of a dome having a partition across it and an air valve
at the top substantially as described.
4. Water closets substantially as described and shown in the drawings.
