IMPROVEMENTS IN WATER CLOSET APPARATUS
Year: 1884

page_text: I SAMUEL WELMAN of Church Street Godalming Surrey Architect do hereby
declare the nature of my invention for IMPROVEMENTS IN WATER CLOSET
APPARATUS to be as follows:→
The apparatus is made of a pan or basin of ordinary shape with a flushing fan or
rim.
The outlet is placed at the back and the outlet pipe or arm is turned upwards
and in a line directly behind or inclining to the right or left of the centre line.
The rise given to the outlet arm is made sufficient to secure a trap or water seal
in the pan or basin.
The upper end of the outlet arm is connected with the soil pipe by means of a
metal joint or flexible tube working air and water tight which allows of the pan
or basin being lifted up to discharge its contents.
The lifting of the basin brings the outlet arm into a right line with the con-
necting soil pipe in which position both bave a like fall and the contents of the
pan flow away without obstruction.
To work the apparatus the pan or basin is secured to the Seat and a portion of
the Seat is made to lift with the pan to the height required.
The lifting Seat is also connected with the arm or lever of the valve which
supplies the water to the apparatus and the Valve is opened and the pan is
therefore flushed and refilled by the lifting action.
Dated this twenty second day of January 1884.

page_text: I SAMUEL WELMAN Godalming Surrey Architect do hereby declare the nature of
my invention for IMPROVEMENTS IN WATER CLOSET APPARATUS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The apparatus is made of a pan or basin of ordinary shape with a flushing rim
or fan.
The outlet is placed at the back and the outlet pipe or arm is turned upwards
and in a line directly behind or inclining to the right or left of the centre line.
The rise given to the outlet arm is made sufficient to secure a trap or water seal
in the pan or basin.
The upper end of the outlet arm is connected with the soil pipe by means of a
joint of metal or other suitable material or by a short length of flexible tubing
working air and water tight which allows of the pan or basin being lifted up
discharge its contents.
to
The lifting of the basin brings the outlet arm into a line with the connecting
soil pipe and in its raised position the arm has a fall similar to that of the soil pipe
which allows the contents of the basin to flow away without check or obstruction.
To work the apparatus the pan or basin is secured: to the seat and a portion of
the seat is made to lift with the pan to the height required.
The lifting seat is also connected with the arm or lever of the valve which
supplies the water to the apparatus and the valve is opened and the pan flushed
and refilled by the lifting action.
The accompanying diagrams illustrate the Closet apparatus and the manner in
which the same works.
Plan and Section No 1. show an apparatus in which the outlet arm turns to the
right or left of the centre line as may be required and the enlarged portion A A,
shows the joint the same being two circular vertical faced plates working together
and kept close to each other by a clip or collar screwed on to one plate and
overlapping the other in such a manner as to admit of studs and small spiral
springs between the collar and plate.
The Collar does not continue quite round the circle but is cut to allow of the
action of the moveable part.
The pan would be set in an iron frame and a dead centre would be provided on
which the whole would rest and work when being lifted to avoid a twisting action
on the joint.
The seat would also have a counter balance weight fixed in position to destroy
an excess of weight that would otherwise have to be lifted.
The Connection to the water supply is made by a short length of flexible tubing
to allow of the lifting of the pan.
Plan and Section No 2 show an apparatus in which the outlet is straight behind
on the centre line.
When a short length of flexible tubing is not used admitting of the lifting
motion of the pan a joint as shewn on enlarged section B. B is adopted.
The centre or working part of the same is slightly tapered from side to side and
a spring and nut keep the plug up in its position.
Plan and Section No 3. shew an apparatus in which the outlet arm has a bend to
the right or left as well as a rise sufficient to form a trap.
The joint for this form is shewn at C. C The pan being kept up to its position
by a spiral spring or screw acting from a cast iron or other frame.

page_text: The Section No 3 also shews the manner in which the Woodwork is arranged to
allow of the lifting of the pan.
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 lifting action as applied to Water Closets.
2, The combination of the lifting action of the pan with the action of the joints
and soil pipe.
3. The Contrivance of discharging the Contents of the pan directly into the soil
pipe so as to avoid a chamber for foul gasses not capable of being fully flushed and.
cleaned at every action of the apparatus.
