I FREDERIC SAWYER WINSER of 52 Buckingham Palace Road Westminster in the
county of Middlesex, Sanitary Engineer do hereby declare the nature of this inven-
tion to be as follows:-
My invention has for its object an improved construction of flushing tanks, cisterns
&c., by means of which a certain portion of liquid retained in such tank or cistern
may be used as an after flush to a closet urinal or the like.
I arrange in the tank or cistern two divisions, chambers or partitions of suitable
capacity and shape, one being of lesser capacity than the other.
In the larger chamber so formed I place a suitable valve connected to the main
discharge pipe or drain.
In the lesser chamber I place a cock or siphon which allows liquid to pass away
more or less quickly from the same and in this chamber I fit or fix a float which is
connected to the valve in the larger chamber by means of lever and chain or other
suitable equivalent.
As the liquid runs out of the tank or cistern the contents of the smaller chamber
containing the float are emptied. The float sinking pulls up or opens the valve in
the large chamber so giving the after flush.
When the lesser division is again so far filled as to raise the float the valve in
the larger chamber sinks, closing the connection to the outlet pipe or drain and
the apparatus is again ready for a fresh operation of the apparatus.

Improvements in Flushing Tanks or Cisterns.
I FREDERIC SAWYER WINSER of 52 Buckingham Palace Road in the City of
Westminster Sanitary Engineer, 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 has for its object an improved construction of flushing tanks,
cisterns and the like by means of which a certain portion of liquid retained by
suitable means within such tank or cistern may be used as an after flush to a
closet urinal and the like.
Referring to the accompanying drawings I arrange in the tank or cistern A
two divisions chambers or partitions one of which I prefer to make of a square
or rectangular section open at the top such as is shewn at B on the said drawing
and the other and smaller one of a cylindrical shape as C, closed at the top-
having less capacity than B. In the larger chamber B I place a suitable
valve D closing a connecting pipe E leading to the main outlet or discharge
pipe, and in the drawing this connecting pipe as shewn as being outside the
cistern or tank, but the whole may be arranged to be contained within the
cistern or tank if desired.
In the lesser chamber C is a cock or syphon F allowing liquid to pass from
the same and in this chamber I fit or fix a float G which is connected to the
valve D in the larger chamber B by means of a lever H, and chain I or other
suitable equivalent.
The action of my arrangement for after flush is as follows:-
When the tank or cistern A is filled the chambers B and C also become full
of liquid so raising the float G in chamber C and closing the valve D in the
chamber B.
When the main body of liquid is discharged from the cistern that contained in
chamber B is retained therein until a certain quantity still remaining in chamber C
has slowly run through cock F when the float G descends actuating the lever H
and chain and so opening the valve D in chamber B and permitting the liquid
therein to escape down pipe E to the main discharge so effecting an after flush:
which serves to refill the basin of the closet after the handle or other connection
has been released.
When the lesser division C is again filled through F so as to raise the float G
the valve D in chamber B returns to its seat.and permits such chamber to become
full by the flow over the top thereof of the water or liquid in the cistern A when i
such has attained the requisite level.

page_text: 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. In cisterns for water closets urinals and the like the employment of two
separate chambers enclosed and arranged therein and supplied with cocks, floats
and valves for the purpose of effecting an after flush substantially as herein
described.
2. The improved construction and arrangement of cistern for water closets
urinals and the like substantially as herein described and illustrated by the accom-
panying drawings.
