I LEONARD EDWIN SUNTER, of 18 Carlisle Street, Lambeth, in the County of
Surrey, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to water closets and comprises the improvements hereinafter
described.
According to my said invention I arrange in proximity to the pan a vertical tube
which communicates with the soil-pipe and into which the said pan directly opens at
its lowest part with or without the intervention of a trap.
Within the said vertical tube is fitted a sliding plug, which is hollow for a portion
of its length and provided with an opening corresponding in size and shape with the
opening between the pan and vertical tube; so that when the said openings coincide
the contents of the pan are free to flow through the said plug into the soil-pipe.
When a solid portion of the plug is placed opposite the communicating opening
between the pan and the vertical tube communication between the pan and the soil
pipe is cut off.
The operation of the said plug to cause its opening to coincide with the opening
from the pan is effected by lifting the plug, by means of a suitable connection from
the outside. When closing the opening the plug will descend with sufficient force to
cut through any obstructions such as paper which may adhere around the opening.
The plug also when descending serves as a force pump to move any accumulation in
the soil pipe. A spring may be provided to act upon the plug and assist the closing
of the same after it has been lifted.
In order to form a tight joint between the interior of the vertical tubo and the plug,
to avoid on the one hand the escape of sewer gas upwards, and on the other hand the

page_text: leakage of water from the pan, I preferably provide the said plug with one or more
cup leathers or the like which fit tightly into the vertical tube.
One great advantage of the improved water-closet is that pieces of paper are not
liable to prevent the valve from being completely closed as is so often the case in
water-closets having hinged valves.
To prevent the escape of gas around the rod for operating the plug I preferably
arrange the same in connection with a stuffing box provided with a gland so that the
packing can be tightened around the said rod from time to time as required.

page_text: I, LEONARD EDWIN SUNTER, of 18 Carlisle Street, Lamboth, in the County of
Surrey, 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:
My invention relates to water-closets and comprises the improvements hereinafter
described.
Water-closets as hitherto generally constructed wherein the pan is closed at its
lower end by a valve, are disadvantageous for the reason that pieces of paper or other
material are liable to become jammed between the valve and the bottom of the pan
and thus allow the water to run completely out of the said pan.
The main object of my invention is to obviate this defect. For this purpose I
arrange in proximity to the pan a hollow cylinder or cylindrical valve-seating or
casing in which a hollow plug or valve is fitted to turn or slide as hereinafter
described, and which communicates with the soil pipe. The pan is connected at its
lower end to the said cylinder or casing either directly or with a trap intervening
between the aperture in the bottom of the said pan and the said hollow valve seating
or casing.
In the accompanying drawing I have shown how my said invention can be
conveniently and advantageously carried into practice.
Figure 1 is a vertical central section of one form of my improved apparatus.
Figuro 2 is a rear elevation and
Figure 3 a plan of the said hollow cylindrical valve seating or casing, and plug
or valve.
Figure 4 is a rear elevation of the said hollow cylindrical plug or valve.
Figure 5 is a side elevation showing a slight modification of my said invention.
Like letters indicate corresponding parts throughout the drawing.
A is the pan, B is the seat, and C is the soil pipe of a water closet.
a is the hollow cylindrical valve seating or casing, which is provided with flanges
having suitable recesses for packing. The hollow cylindrical valve seating or
casing a has morcover a cap c with a hole d for the valve rod e to pass through, and
a recess f forming a stuffing box into which fits the gland or the said cap c is
provided with any other well known means of forming an air tight joint round the
valve rod e. The valve rod e is made square in transverse section or of any section
that will prevent the same from turning in the socket e¹ fixed to the seat B through
which the said valve rod e passes, and is connected to a plate fixed to the upper
extremity of the hollow cylindrical plug or valve h by means of a collar a screw
threaded portion 2 and a nut ³ or otherwise. The hollow cylindrical plug or valve h
slides inside the said hollow cylindrical valve casing or seating a and is open at the
lower extremity and is moreover provided with an aperture i corresponding in size,
and shape with an aperture a¹ in the hollow cylindrical valve casing or seating a
communicating with the bottom of the pan A so that when the said apertures i and a¹
are caused to coincide the contents of the pan A are free to flow through the hollow
plug or valve into the soil-pipe C. When a solid portion of the plug or valve h
is placed opposite the aperture a' communicating between the bottom of the pan A
and the cylindrical valve seating or casing a communication between the bottom
of the pan A and the soil-pipe C is cut off as shown in Figure 1.

page_text: The said hollow plug or valve his operated as follows that is to say to cause
the aperture to coincide with the aperture a¹ communicating with the pan A the
said hollow plug or valve his lifted by means of the valve rod e which can be
operated by the handle j from the ousite of the seat B. When closing the
aperture a by depressing the hollow plug or valve by means of the handle j
sufficient force may be exerted to cut through any obstructions such as paper
which may adhere around the openings a¹ and i. The hollow plug or valve h
when descending also serves as a force pump and acts so as to move any
accumulation that may have lodged in the soil pipe C. I sometimes employ a
suitable spring so arranged as to act upon the hollow plug or valve and assist
the closing of the same, after it has been lifted.
In order to form a tight joint between the interior of the hollow cylindrical
valve seating or casing a, and the hollow plug or valve so as to avoid on the
one hand the escape of sewer gas upwards, and on the other hand the leakage of
water from the pan, I provide the said hollow plug or valve with cup leathers
or other packing inserted in the in the recesses b₁ between the flanges b.
The escape of sewer gas round the valve rod e is prevented by the stuffing box f
and the gland g. The packing in the said stuffing box f can be tightened round
the said valve rod e from time to time as required by means of the bolts and nuts g¹,
or any other convenient means.
Figure 5 is a side elevation showing a slight modification of my said invention. In
this instance the handle j is attached to a round valve rod e. Instead of pulling up
and depressing the valve in order to cause the aperture i in the latter to coincide
with or move away from the aperture a¹ in the hollow cylindrical valve seating or
casing a communicating with the pan A, the said valve is so arranged that the
aperture is always upon the same level as the aperture a¹. In order to cause the
aperture i to correspond with the opening or aperture a¹ or vice versa the handle j is
turned round. A suitable collar or collars are provided to retain the valve rod e and
prevent end wise movement of the same, and also a stop or stops to prevent the
valve from being turned too far in either direction.
It is obvious moveover that I can modify the construction of my said invention
without in any way departing from the nature of my said invention.
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
First. A valve comprising a hollow cylindrical plug provided with a suitable
aperture and adapted to slide or to turn in a cylindrical seating or casing to bring the
said aperture into coincidence with or move it away from a corresponding aperture in
the said seating or casing, substantially as, and for the purpose, set forth.
Second. The combination, with a water-closet pan, of a valve comprising a hollow
cylindrical plug fitted to slide or to turn in a hollow cylindrical seating or casing,
substantially as, and for the purpose, herein before specified.
Third. The improved apparatus consisting of the parts constructed and combined
substantially as described with reference to figures 1 to 4 of the accompanying
drawing.
Fourth. The modification of my invention substantially as described with reference
to figure 5 of the accompanying drawing.
