PROVISIONAL SPECIFICATION.
Improvements in Water Waste Preventers.
WILLIAM ROSS Junior of 44 South Portland Street, Glasgow in the County
of Lanark, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in apparatus for the prevention of waste
of water supplied to water closets, urinals & other appliances in the manner after
described & shown in the accompanying drawing.
A syphon of improved form is used in combination either with a waste preventing
valve as shown in the accompanying drawing or in combination with a common
valve. The drawing shows the improved syphon S which is formed of a single
length of tube bent in two places, & having attached to one end the seat of a waste
preventing valve V. An outlet nipple O is attached to the lower bend & passes
through the bottom of the cistern & connected to the down pipe. In working
the apparatus the valve V is opened by pulling the cord attached to the lever L
when the water rushing down the valve seat exhausts the syphon & causes it to act.
The waste preventing valve closes automatically before the water in the cistern falls
to the level of its seat V thus allowing the water to discharge till it reaches the
lower end of the syphon at A when the flow stops on the admission of air.
This arrangement is for direct flushing as the flow of water takes place
immediately on pulling the cord. The waste preventing valve is engaged again by
the weighted lever L on letting go the cord.
Dated this 29th day of September 1892.

COMPLETE SPECIFICATION.
Improvements in Water Waste Preventers.
I, WILLIAM ROSs Junior, Engineer presently residing at No. 44 South Portland
Street, Glasgow, Scotland do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention consists of improvements in apparatus for the prevention of waste
of water supplied to water closets, urinals and other appliances in the manner
herein described, and shewn in the accompanying drawing, and in the drawing "left
with the Provisional Specification."
A syphon of improved form is used in combination either with a waste preventing
valve as shewn in drawing Sheet I "left with the Provisional Specification," or in
combination with a common valve.
Sheet I left with the Provisional Specification" shews the improved syphon S
which is formed of a single length of tube bent in two places, and having attached
to one end the seat of a waste preventing valve V. An outlet nipple O is
attached to the lower bend and passes through the bottom of the cistern C and
connected to the down pipe.
In working the apparatus the valve V is opened by pulling the cord attached
to the lever L when the water rushing down the valve seat exhausts the syphon
and causes it to act. The waste preventing valve closes automatically before the
water in the cistern falls to the level of its seat V thus allowing the water to
discharge till it reaches the lower end of the syphon at A when the flow stops on
the admission of air.

page_text: This arrangement is for direct flushing as the flow of water takes place
immediately on pulling the cord. The waste preventing valve is engaged again by
the weighted lever L on letting go the cord.
Another form of syphon is shewn in drawing-Sheet II suitable for fixing into
small lead cisterns. The inlet and outlet ends of the syphon S are relatively at
right angles or more or less, in plan. This shape enables the syphon S to be
screwed into a ring R which is fixed to the bottom of a cistern C of very limited
size.
A common valve may be attached to the syphon instead of the waste preventing
valve described above and shewn in Sheet I "left with the Provisional Specifi-
cation." In this case the syphon will be charged on raising the valve as described,
& shewn in said Sheet I. If the water level in the cistern C falls below the valve
seat V before the valve is closed, the flow of water will then cease, but if the valve
be closed when the syphon is charged, and before the water level has fallen to the
valve seat V, the flow will continue till air enters the lower end A of the syphon S.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. An improved form of syphon S as described above, and as shewn in the
drawings.
2. The improved syphon S as above described and shewn in combination with a
waste preventing valve as above described and shewn in the drawings.
3. The improved syphon S as above described in combination with a common
valve.
Dated this 17th day of June 1893.
