PROVISIONAL SPECIFICATION.
Improvements in Syphon Water Waste Preventers.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford, in the
County of Kent Engineers and DAVID CAMPBELL PINHEY of 6 Albion Road,
Lewisham, in the County aforesaid, in the employ of the said firm do hereby
declare the nature of this invention to be as follows:-
This invention is of special advantage for flushing water closets in houses. The
cistern bottom is formed with a well of circular or other suitable form provided
with an interior charging or flushing "cylinder" open below and having an easily
fitting piston which can be raised by connection to the pull handle. The cylinder
is so fitted in the well that the water in the latter can refill the cylinder after a
discharge. On the cylinder, and it may be cast in one therewith, is mounted an
upright pipe, and over this a larger pipe with annular space between the two
below communicating with the water in the cistern and the outer pipe terminating
in a downwardly discharging syphon pipe the bend of which may be above the
normal water level in the cistern. By acting on the pull the piston is raised
whereby the water contained in the cylinder is forced into the discharge pipe and
the syphon action started so that the contents of the cistern are emptied into the
discharge.
The cylinder may be formed with two or more lugs for fixing it to the cistern.
To admit the water from the well to the cylinder an annular space may suitably be
left between them.

COMPLETE SPECIFICATION.
Improvements in Syphon Water Waste Preventers.
We,
EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford in the
County of Kent Engineers and DAVID CAMPBELL PINHEY of 6 Albion Road
Lewisham in the County aforesaid in the employ of the said firm 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 of special advantage for flushing water closets in houses and
comprises a simple cheap and efficient improved construction of syphon water waste
preventer.
Figure 1 of the accompanying drawings is a vertical longitudinal section and
Figure 2 a plan view of our invention.
The bottom of the cistern A is formed with a well A¹ of circular or other suitable
form provided with an interior charging or flushing cylinder B open below and
having an easily fitting piston C which can be raised by connection to the pull
handle for instance as shewn by the levers D and E on the weighshaft F and the
connecting rod G which is jointed to the piston rod H which passes out through
the top B of the cylinder. The cylinder B is so fitted in the well A¹ that the
water in the latter can refill the cylinder B from below after a discharge; for this
purpose an annular space may be left between the bottom of the cylinder B and the
inner bottom of the well A' as shewn.
On the cylinder B and by preference cast in one therewith is mounted an upright
Pin 977

page_text: pipe I and over this is a larger pipe K with annular bell-mouth like space between
the two communicating below with the water in the cistern A. and the outer pipe K
terminating in a downwardly discharging syphon pipe L the bend of which may as
shewn be above the normal water level in the cistern.
By acting on the pull the piston C is raised from its normal down position shewn
whereby the water contained in the cylinder Bis forced into the syphon K L and
discharge pipe L' and the syphon action started-so that the contents of the cistern
are.emptied into the discharge.
The cylinder may be formed with two or more lugs B* here shewn four in number
for fixing it to the cistern.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A syphon water waste preventer comprising a cistern with well A', a cylinder B
fixed therein with communicating space between the two, a pipe I rising from the
top B' of the cylinder into the leg K of a syphon K L and a piston B with piston
rod and connection to the pull for raising it and thereby starting the syphon action
substantially as set forth.
