AN IMPROVED WASTE WATER PREVENTER
Year: 1884

page_text: I RICHARD CHANTRY of 67 Brandon Street Walworth in the County of Surrey
Zinc Worker do hereby declare the nature of said Invention for AN IMPROVED
WASTE WATER PREVENTER to be as follows:-
According to this Invention my improved waste water preventer consists of a
cylinder having holes at top and bottom and in this cylinder I fit a piston.
I form the lower part of said Cylinder larger in diameter inside than the upper
part. I fix a horizontal diaphragm in the cistern and through this I fix the above
described apparatus with the larger diameter of cylinder in the lower division of
cistern. The piston rod is so connected with the plug rod that when the plug is
pulled up the piston is drawn up to the smaller part of cylinder in which it fits,
thereby shutting off communication between the upper and lower compartments in
the cistern and allowing only the water contained in the latter to be discharged
through the ordinary valve. When the plug is let down again the piston again
descends into the larger portion of the cylinder so as to allow the water to pass
through same by means of the aforesaid holes and recharge the lower compartment.
Although I have described my improved waste water preventer fitted in the
cistern as being preferable it is obvious it might be fitted at top of same in a small
extra cistern,

Zinc Worker do hereby declare the nature of "AN IMPROVED WASTE WATER
PREVENTER" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
According to this invention my improved waste water preventer consists of a
cylinder having holes round same near top and bottom in which cylinder I fit
a piston having a washer of rubber or other suitable material fitting said cylinder.
In the flushing cistern I fit horizontally a diaphragm so that the lower compart-
ment shall contain only the desired quantity of water (say two gallons for example)
and through this diaphraym I fit the above described apparatus the piston rod
fitted to the aforesaid piston being so connected with the closet lever or otherwise
so that when such lever is actuated the said piston is drawn up in order to shut
off the communication between the upper and lower compartments of the flushing
cistern thus allowing only the water contained in the lower compartment to be
discharged through the ordinary valve. When the closet lever is released again
the piston again descends so as to form a communication between the two com-
partments in the flushing cistern by means of the holes aforesaid thus recharging
the lower compartment.
And in order that my said invention may be better understood I will now
describe the same with reference to the accompanying sheet of drawings which
shews section of my improved apparatus fitted to the flushing cistern.
DISCRIPTION OF THE DRAWING.
a shews cylinder having holes 6 therein near top and bottom. c shews washer of
india rubber or other suitable material fixed on the top of piston d. e shews piston
rod. shews diaphraym. h is a cap to cylinder provided with seating i so as to
keep the washer flat. The apparatus is shewn as it would appear when the com-
munication is shut between the two compartments g and g¹ of the flushing cistern,
the dotted lines shew the position of piston d and washer c when the communica-
tion between the two compartments is open the water passing through the holes b.
The action is as follows:-The piston rod being suitably connected with the closet
when it is desired to flush the same, the piston d and washer c are caused to ascend
and assume the position shewn in the drawing so as to shut the communication
between the compartments g and g¹ the ordinary round valve at the same time
being opened allows the water in compartment g¹ to be discharged and upon
releasing the lever the piston d and washer c descend as shewn by dotted lines
in the drawing when the lower compartment will fill by means of the holes b.

page_text: 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
The improved waste water preventer consisting of cylinder with holes near top
and bottom and fitted with piston and washer in combination with flushing
cistern separated into two compartments all constructed and operated substantially
as set forth.
