Improvements in or relating to Water Closets.
I JOSHUA VALENTINE EVES of the Forth River Mills Falls Road Belfast in
the County of Antrim Ireland Mill Manager do hereby declare the nature of the
said invention to be as follows:-
:―
This invention is designed with the object of securing a large quantity of water
in the pans of water closets without the use of valves or plugs and at the same time
providing means for their free and quick discharge.
It consists essentially of a movable or swivelling trap connected to the pan the
bend of which is of a height equal to the depth of water required in the pan. By
turning the trap to one side or the other the contents of the pan is allowed to flow
away down the soil pipe.
In carrying out the invention the pan of the water closet may be constructed of
any suitable forin with an opening in the bottom or side leading to a terminal pipe.
Between this pipe and the soil pipe by means of suitable joints is fixed a syphon trap
of inverted or other convenient form. The inside bend of this trap may be
4. 5 or more inches long according to the depth of water required to be maintained in
the pan. The joints forming the connection between the trap and the other pipes
may be made of lignum vitae vulcanised fibre or other material which will resist the
action of the fluids passing through the pipes and at the same time form a close and
swivelling joint. A lever chain or connecting rod is attached to the trap and
connected with the flushing handle of the closet. In normal position the trap is
vertical when it is desired to discharge the contents of the pan the trap by means of
the handles and lever is brought to a horizontal position or any angle approaching
the same that may be desired and the contents of the pan flows freely through or the
trap may be made to move through a whole revolution until the trap is again vertical.

page_text: If thought desirable an ordinary trap of shallow seal may be placed at a lower level
between the soil pipe and swivelling trap.
The chief advantage of this invention I consider is that a greater quantity of water
can be maintained in the pan to receive and deodorize the foecal matter than in
closets known as "flush outs" while at the same time no difficulty is experienced in
completely and quickly discharging the contents of the pan without the use of valves
or plugs in its orifice."

1, JOSHUA VALENTINE EVES, of the Forth River Mills, Falls Road, Belfast, in the
County of Antrim, Ireland, Mill Manager, 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 :-
This invention is designed with the object of securing a large quantity of water in
the pans of water closets without the use of valves or plugs while at the same time
providing means for their free and quick discharge.
pan
It consists essentially of a movable or swivelling trap or bend connected to the
the bend or trap being of a height equal to the depth of water to be maintained
in the pan. By turning the trap or bend to one side or the other the contents of the
pan is allowed to flow away down the soil pipe.
Referring to the annexed drawings
Fig. 1 is a sectional elevation showing parts of water closet constructed according
to my invention.
Fig. 2 end elevation of same.
The pan A of the water closet may be constructed of any suitable form with an
opening in the side or in the bottom as shown leading to a terminal pipe B. This
pipe B also serves as the stand for the pan A it is preferably made of cast iron and
enamelled. Between the pipe B and the soil pipe C is placed the syphon trap or
bend D of inverted U or other convenient form. The trap or bend D is fitted to the
pipe B and soil pipe C by suitable joints upon which it is capable of turning or
swivelling. The height of the bend D may be 4 or 5 inches more or less according
to the depth of water required to be maintained in the pan.
The joints between the pipes B and C and the bend D I prefer to make of
brass. On to the end of the pipe B a brass ring E is shrunk and faced to meet
the face of the ring e on the end of the bend. On the soil pipe end the brass
ring F slides and is held closely against the ring by the ring G and stuffing g.
The screws H, acting upon the ring G keep the trap or bend in position and the
joints tight. 1, are oil cups or lubricators which hold a supply of oil for lubricating
the joints which passes down between the brass rings through the groove i.
The T picce K is a web which connects together and strengthens the two
lower ends of the bend or trap they are preferably made of a casting to which
the upper part is fixed. The upper bend is preferably made of sheet copper or
brass struck or hammered out for the sake of lightness and is brazed to the
lower part. The mouth of the bend next the pan is say 3 inches in diameter the
syphon gradually enlarging to inches at the other end. This contraction of
the trap at the first end gives greater velocity to the discharge and also allows
a fall of about an inch when the syphon is on its side and discharging.
To the web K is connected the quadrant rack L which is operated by the
second quadrant M and handle N. The pulling of the handle forward in the

page_text: direction of the arrow moves the quadrants L and M turns the trap or bend D
about its axis and allows the contents of the pan to discharge itself into the soil pipe.
Instead of the quadrants shown any other suitable arrangement of mechanism may
be adopted to move the swivelling bend and trap D such as a lever, chain, etcetera
attached to the flushing handle and a weight or spring may be employed to return
the trap or bend D to a vertical position.
In the drawings I do not show any water pipes or flushing apparatus as any of
the numerous well known forms at present used with water closets may be employed.
A lever attached either to one of the quadrants or to a snug cast to the swivelling
bend may be employed to operate the trap or valve governing the water supply.
It will also be obvious that the invention is not limited to the details herein set
forth as pans of any suitable shape or construction may be used and the swivelling
bend may if desired be made of other material than brass or copper and also may be
made all of one piece.
In normal position the trap or bend D is vertical when it is desired to discharge
the contents of the pan the trap by means of the handle and quadrant levers is brought
to a horizontal position shown in dotted lines or to any angle approaching the same
that may be desired and the contents of the pan flows freely through. If desired the
trap or bend D may be made to move through a whole revolution until the trap is
again vertical. If thought desirable an ordinary trap of shallow seal may be placed
at a lower level between the soil pipe and swivelling trap.
The chief advantage of this invention I consider is that a greater quantity of water
can be maintained in the pan to receive and deodorize the foccal matter than in closets
known as "flush outs" while at the same time no difficulty is experienced in com-
pletely and quickly discharging the contents of the pan without the use of valves
or plugs in its orifice.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
1. A water closet having a trap or bend higher than the discharge orifice to retain
a quantity of water in the pan movable or swivelling about its joints so that it can be
lowered to effect the discharge of the contents of the pan substantially as described.
2. In a water closet the combination with the pan of a swivelling trap or bend
moved by levers or their equivalent which when vertical retains a quantity of water
and when lowered discharges the contents of the pan substantially as described.
