PROVISIONAL SPECIFICATION.
Improved Siphon Water Waste Preventer.
WILLIAM RICHARD CLARK of 71 Danby Street Peckham in the County of
Surrey Mechanician do hereby declare the nature of this invention to be as
follows:-
My invention relates to a simple siphon apparatus for flushing and afterflushing
closets &c. The stand pipe which rises above the water level, is covered by a
bottle shape or conical cap, the larger end of the cap being near the bottom of the
cistern. A cover is fixed over the lower end of the cap with an opening in the
center for the stand pipe to pass through the said cover, openings are made in
the cover to admit water into the cap, and the openings can be so made, or plates
can be so fixed on the upper side of the cover, that the water enters the cap in
nearly a horizontal line. One or more covers can be placed in the cap. By raising
the cap quickly, the water enclosed in the cap is driven upwards by the action of
the cover, and the siphon is put in action. The afterflush is caused by a small pipe
or siphon that has one end inserted in the mouth of the stand pipe and the other end
in a small chamber enclosed in the cistern the top of the said chamber to be above
the water line. The action of the large siphon puts the small siphon into operation
and continues after the large siphon is done. The water is admitted to the afterflush
chamber through a small hole near the water line, the hole to be smaller than the
small siphon so there should be no possibility of a continuous action.

COMPLETE SPECIFICATION.
Improved Syphon Water Waste Preventer.
I, WILLIAM RICHARD CLARK of 71 Danby Street Peckham in the County.
of Surrey Mechanician do hereby declare the nature of the said invention and, in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to syphon apparatus for flushing water closets and the like
and consists in an improved or simplified construction of same, which I shall now
describe, with reference to the accompanying drawings.
Fig. 1 is a vertical section of one form of my improved syphon flushing
apparatus;
Fig. 2 is plan view of the bottom cover of the outer annular leg of the syphon
and
Fig. 3 a side view of same.
The stand pipe A or inner leg of the syphon rises above the water level and is
covered by the outer cap or annular leg B which is of bottle shape the larger end
A cover B is fixed over the
of the cap being near the bottom of the cistern C.
lower end of the cap B with an opening in the centre for the stand pipe A to pass.
through and with openings B* to admit water from the cistern C into the cap B in
a somewhat lateral direction practically preventing the flowing back of the body of
water contained in cap B when the latter is raised and causing the water to run
down the inner leg or stand pipe A thus starting the syphon action. D is a lever
with pull chain D₁ for lifting the cap B.
By raising the cap quickly the water enclosed in it is raised with it and driven

page_text: into the stand pipe A thus creating a vacuum and starting the syphon action, the
water will continue to rush up through the openings 13 and down the standpipe A
until the cistern is emptied to the level of the bottom of the cap B.
Fig. 5 is a vertical sectional view of another form of my improved syphon
apparatus
Fig. 6 being a plan of the cap cover and
Fig. 7 vertical section of same.
The standpipe A or inner syphon leg in this case is formed with entrance bell-
mouth at top and outer sleeve part A¹ the pipe A passing into the bottom chamber.
or trap of the cistern C and the sleeve part A' terminating at the bottom of the.
cistern C. The bell-mouth is so formed in order to allow the water to pass down
more freely than if the pipe A were merely formed plain. The top of the bell-.
mouth is as an example shewn above the top of the cistern.
The cap
is also as
an example shewn of a plainer conc form instead of a bottle shape. Its bottom
cover consists of two plates B1 and B2 with intervening space the plate B having'
holes B. These plates are fixed together by wires as shewn at a little distance
from cach other so that the water issuing from the holes B* assumes a somewhat
lateral direction. The plates may however be fixed together in any suitable
manner as long as provision be made for allowing the free entry of the water
between them.
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. In a water waste preventer with annular syphon the application and use with
the outer leg or cap of one or inore covers or pairs of plates with openings so
arranged as to practically prevent the flowing back of the water when the cap is
raised and thus start the syphon action substantially as set forth.
2. The improved syphon water waste preventers shewn on the drawing.
