Improvements in Closet Fittings.
I JOSEPH THOMAS HARRIS of Beaufort Works, Kingston Road, Merton Park,
Surrey Engineer do hereby declare the nature of this invention to be as
follows:-
"
The object of this invention is to combine the advantages of a so-called
"combination wash out closet fitting with those of a valve closet and at the same
time to reduce the latter to an extreme point of simplicity, thus reducing the cost,
promoting the efficiency of action, and also rendering it more easy to clean, should
occasion require.
To this end the invention relates principally to a simplified valve action, to the
general arrangement or form of valve box and pan holder, and to the disposal of
the overflow and trap therefor.
In place of making the valve to close the orifice directly at the bottom of the
pan so that the valve horizontal when closed, the improved valve box or lower
container which is shaped to receive and hold the lower end of the pan, is provided
with a curved passage or channel forming a continuation of the pan, the lower
part of this channel or passage curving round to be horizontal so that the valve
which closes the end of this passage may when closed be either in a vertical or
else in a very oblique position, almost vertical. The valve chamber is therefore
arranged, not below the lower orifice of the pan, but behind the latter and the
front wall of the valve chamber extends upward to a sufficient height and then
returns backwards horizontally still below the level of the top rim of the valve
box.
A space is therefore left in front of the front wall of the valve box and behind
the lower edge of the pan and into this passes a pivoted lever, the pivot being
preferably at or near the upper edge of the front wall of the valve box.
The one arm of lever extends down in front of the opening in the valve box
and is connected with the valve by a pin cast with the valve projecting on the
centre of the face of valve, and thus supports the valve, while the rear arm of the
lever extends rearward above the rim of the valve box and carries the usual
weight which keeps the valve closed, to this arm being also attached such hand
pull mechanism as may be desired.
In the horizontal return bend which forms the roof of the valve box proper is
an opening of considerable size, surrounded by an upturned flange, and over the
latter is a cap with a downturned flange and projection on the inside, for spacing
it from the upturned flange. This device forms a trapped overflow and governs
the level of water in the pan, which water also seals the trap and the space
between the pan and the front wall of the valve chamber proper in which passes
the valve lever.
The cap aforesaid being removeable can be lifted off for cleaning the back of
the valve or interior of the valve chamber proper.
The upper edge or rim of the whole container extends to a suitable height, its
rear part forms the side walls of the overflow trap, its front part is shaped to
receive the lower end of the pan.

Improvements in Closet Fittings.
I, JOSEPH THOMAS HARRIS, of Beaufort Works, Kingston Road, Merton, 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 :-
The object of this invention is to combine the advantages of a so called
"combination" washout closet fitting with those of a valve closet and at the same
time to reduce the latter to an extreme point of simplicity, thus reducing the cost,
promoting the efficiency of action, and also rendering it more easy to clean should
occasion require.
To this end the invention relates principally to a simplified valve action, to the
general arrangement or form of valve box and pan holder, and to the disposal of
the overflow and trap therefor.
In place of making the valve to close the orifice directly at the bottom of the
pan so that the valve is horizontal when closed, the improved valve box or lower
container which is shaped to receive and hold the lower end of the pan is provided
with a curved passage or channel forming a continuation of the pan, the lower
part of this channel or passage curving round to be horizontal or substantially
horizontal so that the valve which closes the end of this passage may when closed
be either in a vertical or else in a very oblique position almost vertical. The
valve chamber is therefore arranged, not below the lower orifice of the pan but
behind the latter and the front wall of the valve chamber extends upward to a
sufficient height and then returns backwards horizontally still below the level of
the top rim of the valve box. A space is therefore left in front of the front wall
of the valve box and behind the lower edge of the pan and into this passes a
pivoted lever the pivot being preferably at or near the upper edge of the front
wall of the valve box. The one arm of this lever extends down in front of the
opening in the valve box and is connected with the valve by a pin cast with the
valve projecting on the centre of the face of valve and thus supports the valve,
while the rear arm of the lever extends rearward above the rim of the valve box
and carries the usual weight which keeps the valve closed, to this arm being also
attached such hand pull mechanism as may be desired.
In the horizontal return bend which forms the roof of the valve box proper is
an opening of considerable size, surrounded by an upturned flange, and over the
latter is a cap with a down turned flange around it and projections on the inside,
for spacing it from the upturned flange. This device forms a trapped overflow and
goveins the level of water in the pan, which water also seals the trap and the
space between the pan and the front wall of the valve chamber proper in which
passes the valve lever.
The cap aforesaid being removable can be lifted off for cleaning the back of
the valve or interior of the valve chamber proper.
The upper edge or rim of the whole container extends to a suitable height, its
rear part forms the side walls of the overflow trap, its front part is shaped to
receive the lower end of the pan.
The front wall of the valve box containing the valve seat may in practice con-
veniently be inade removable for purposes of repairing or cleaning.
The following description will illustrate the method of constructing such a valve,
reference being made to the annexed drawing in which
Fig. 1 is a vertical section through the valve box and pan holder and through
the pan fixed in the latter.

page_text: The pan holder with the valve box to the rear thereof is preferably made all in
one casting to present an inverted conical receptacle at a with flanges at bdd to
facilitate the secure packing and tight setting of the pan c. From the rising
flanges d d the casting forms a deep channel e rounded below and running rearward
between two substantially parallel or steeply inclined walls ff up to the vertical
facing plate in which the valve passage way and seat are arranged and which is
hereinafter described. The casting forms a channel or groove f¹ for the reception
of this facing plate and behind the latter it extends and forms a chamber g
substantially D shaped (in plan) having at a certain height a cross floor h and
gradually gathered into a circular form in plan at the base where it is provided with
a cylindrical socket piece or spigot k for attachment to the soil pipe whether trapped
as at or with straight run as at j. A cavity is made in the aforesaid cross
floor or roof and a vertical flange m surrounds this cavity and forms an
overflow.
The exterior surrounding wall of the casting also rides to a height at n equal to
the height of that part which holds the pan and thus forms a D shaped tray above
the valve box 9. Strengthening or fixing ribs and flanges are made where needed
as at o o. A branch pipe p with socket end for connection of a pipe forms a
ventilator for the valve box.
The facing plate 9 is made to fit into the groove fl after insertion of a strip of
rubber or other packing into this groove. The face plate carries a backwardly
extending flange which after insertion of a similar strip of packing s firmly beds
upon the front edge of the floor h. At the ends of the upper edge of the face
plate are pillar blocks tt and after the face plate has been put in position two
lugs uu are inserted in holes in the side walls of the casting and fixed by nuts vv.
Set-screws w w are then screwed through tapped holes in the said lugs and bearing
upon the pillar blocks tt they firmly press the face plate q down upon the packing
and hold it in place in a water tight manner.
The valve which closes on the seating y from inside the valve box g carries
the projecting central pin z which passes through a hole in the end of the lever a¹
and is secured by a nut. This lever a is pivoted by means of a cross roller a³
fixed on it and carried on pivot bearings a a³ formed by screws passed through
the pillar blocks t t before the face plate is inserted.

The lower edge of the pan c may be arched at c¹ to afford view of the valve.
The dome d' over the flange m traps the latter which forms thus a water sealed
overflow which regulates the height of the water in the pan c and in the space
between the pan and the valve-box.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-

1. A pan holder a placed laterally with regard to the valve chamber
leading thereto by a channel e in prolongation of the pan with a valve closing the
passage between said channel and valve chamber having a lever for operating it
outside the valve chamber and passing upward between it and the pan.
2. A pan holder a communicating below with a channel e bounded by side walls ff
and leading to a vertical or substantially vertical face plate with passage and valve
seat therein, a valve chamber rearward thereof having a roof plate with a trapped
opening for overflow therein in communication with said channel e above the face
plate and a valve for closing said passage in the face plate having a lever for
operating it wholly exterior of the valve chamber substantially in the manner
described.
3. A pan holder a communicating below with a channel e bounded by side

and valve seat therein, a valve chamber rearward thereof having a roof plate with
a trapped opening for overflow therein in communication with said channel e
above the face plate and a valve for closing said passage in the face plate having
a lever so connecting the valve with its operating mechanism that the passage 5
through which the lever passes to the valve is always sealed by water.
