PROVISIONAL SPECIFICATION.
Cistern for Water Closets and the like.
HENRY SMITH 34 Spencer Street Lincoln Plumber, Glazier &c., do hereby
declare the nature of this invention to be as follows:-
The arrangement and mode of giving motion to the levers by the seat or cord,
thus making it a self acting closet.
A waste of water preventor.
No water remains in the cistern only when in use, so prevents any corroding or
bursting by frost.
A large flush is obtained with less head owing to the positive action and
arrangement of the syphon.
Self-closing ball tap actuated by its own pressure.
In order that my invention should be understood I will proceed to describe the
same by reference to the accompanying drawings, in which
Fig. 1 is a front sectional elevation, and Figure 2 an end elevation and Fig. 3 a
plan shewing the relative position of levers.
Fig. 4 is a sectional elevation of the water inlet valve.
Similar letters in all the figures represent similar parts.
The cistern I make of wood, lined with sheet lead, or of galvanised iron, or
other suitable material to prevent oxidisation, preferably of copper. The buoy
lever is also made of copper or brass capable of being adjusted by bending, all the
other levers are made of cast malleable, and are galvanised. To work the
apparatus, I pull the lever A down which causes the syphon, one end of which
forms the valve to fit on to its seat, thus closing the outlet pipe B. at the same
time the other end of the lever A at a point a. rises up and lifts the weighted
lever C which is hinged at c. and causes the lever D operating the water inlet
valve E. to fall by its own weight and opening the valve d. thus admitting water
into the cistern. As the water rises, it raises the buoy F. and when it reaches to
a certain level the lever D releases the valve d. and the pressure of water acting on
the top side of the valve d. automatically closes the valve, and no more water is
admitted.
To empty the cistern, the weight hanging on the lever A is released, the
weight f. falls and being hinged at e. the end of the lever A is lifted up, and in
doing so lifts the syphon valve g. allowing the water to flow out by the outlet
pipe B. causing a vacuum in the syphon G. thus part of the water rushes up each
side of the syphon and down the centre of the annular valve and joins the water
flowing down the outlet pipe B. the whole of the water being discharged, the
weight f. keeps the outlet valve open, and the weighted lever C. keeps the buoy up,
and no water enters the cistern until the lever A is pulled down.

HENRY SMITH 34 Spencer Street Lincoln Plumber aud Glazier, 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:-
My invention relates chiefly to cisterns for water closets, and the like.
One feature of the invention consists in operating the ball valve by its own
pressure.
The syphon which I employ being arranged as an overflow, and forming the
annular outlet valve in combination.
The arrangement of syphon and valve so that I can discharge the contents of
the cistern, having only a minimum quantity of water, making it efficient for
urinal purposes.
The arrangement of, and combination of levers, working the cistern, which only
admits water into the cistern wben in use, no water remaining in the cistern when
not used, also the provision made for overflow, in the event of injury to the water
inlet valve, when the cistern is already full of water.
No water being in the cistern when not in use I entirely prevent fracture of the
cistern by frost, and reduce corrosive action to a minimum.
Immediately the hanging cord or seat of the closet is moved, the outlet valve is
closed before the ball tap can open the water inlet valve, thus waste of water is
prevented.
In order to work the cistern, I connect the lever to the seat, or work by a cord,
thus making it a self acting closet.
In order that my invention should be understood, I will proceed to describe
the same by reference to the drawings left with my Provisional Specification, in
which
Fig. 1. is a front sectional elevation, Fig. 2. an end elevation, Fig. 3. a plan
shewing the relative position of levers.
Fig. 4. a sectional elevation of the water inlet valve.
Similar letters in all the figures represent similar parts.
The cistern I make of wood lined with sheet lead, or of galvanised iron, or other
suitable material. The syphon I prefer to make of copper, the buoy lever made of
suitable material capable of being adjusted by bending, all the other levers 1 inake
of galvanised malleable iron, I support lever C by two projecting arms cast on
lever A, and hinge it at the point marked c.
To work the apparatus, I pull down the lever A which on its descent allows the
syphon having an annular ring at the bottom forming the outlet valve to fall on to
a brass seating, thus closing the outlet pipe B. at the same time the other end of
the lever A at a point marked a. rises up and lifts the weighted lever C. hinged at c.
and causes the lever D. operating the water inlet valve E. to fall by its own weight
and opening the valve d. thus admitting water into the cistern. As the water rises,
it comes into contact with the buoy F. and when the water reaches to a certain
level the lever D releases the valve d. and the pressure of water being on the
top side of the valve d. automatically closes the valve, no more water being
admitted.
To empty the cistern, a weight is released by the seat or cord which hangs on
the end of the lever A. the weight f. falls, and the lever being hinged at e. the end
of the lever A. is lifted up, and in doing so lifts the syphon valve G. allowing the
water to flow out by the outlet valve B. causing a vacuum in the syphon G. thus
part of the water is forced up each side of the syphon which has a partition in the
centre, to direct the water uninterruptedly down the centre of the annular valve,

page_text: and joining the water already flowing down the outlet pipe B. the whole of the
water being discharged, the weight f. keeps the outlet valve open, and the weighted
lever C. keeps the buoy up, and no more water enters the cistern until the lever A.
is pulled down.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is:
1. The arrangement & mode of operating the whole of the levers by one
movement of the seat or cord, making it a self acting closet.
2. No water being left in the cistern, only when in actual use, fracture by frost
is prevented and corrosion reduced to a minimum.
3. The outlet valve being on its seat first, a waste of water is prevented.
4. The positive action and arrangement of the syphon, being able to discharge
its contents with only a minimum amount of water.
5. The self acting ball tap, being actuated by its own pressure.
6. The arrangements made for overflow, in the event of any injury to the ball tap
valve, the surplus water passing down the syphon.
