PROVISIONAL SPECIFICATION.
An Improved Water-waste Preventer.
1, JOHN CHARLES GARROOD, Plumber of 5 Shellons Street Folkestone in the
County of Kent do hereby declare the nature of this invention to be as follows:-
In the cistern I erect a vertical cylinder open at both ends. Near the top, a
branch bent pipe is attached, to conduct the water rising through the cylinder, to
the closet pan. In the cylinder I fix a bucket with a valve, and attach thereto
a hollow piston rod. In the upper part of the cylinder, above the branch pipe, I
place a stuffing box, which acts as a regulator. The hollow piston is perforated
below the stuffing box. When by means of a lever the bucket is raised, the water
syphons down to the closet pan. The piston then commences to descend gradually,
When the
but the water continues to syphon through the valve in the bucket.
perforated portion of the hollow piston has descended through the stuffing box, the
air bus access to the cylinder and causes the action of the syphon to cease.
The advantages of this arrangement are as follows.
1st. The action is noiseless there being no gurgling or rush of wind as the cistern
is emptying.
2nd. By means of the regulator, the quantity of water syphoned, can be limited
to any particular amount; thus waste of water is prevented.
3rd. This improvement can be fitted to a valve closet & would thus save the
expense of a stool-cock and regulator. To effect this, I make a false bottom in the
cistern. The down pipe passing through this compartment is perforated. This
compartment, with a properly constructed vent, is supplied with water by the
down pipe while the flushing is going on. The water thus stored, is used as an
after-flush.
Dated this Eleventh day of April 1894.

I, JOHN CHARLES GARROOD, Plumber, of 5 Shellons Street, Folkestone in the
County of Kent 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 :-

The action of the improvement is as follows. When the forked lever
moved by trigger pull "J," the hollow piston rod "C" and bucket are raised and
cause the water to rise and syphon through the down pipe. The lever "F" being
released automatically by the trigger pull, the hollow piston rod commences to
descend. The water still rises through the valves. When the perforated portion
of the hollow piston rod descends below the stuffing box "D," the air has access
to the cylinder and stops the syphoning action. The descent of the hollow piston
rod is regulated by the stuffing box and by adjusting a weight on the lever "F."
The descent of the hollow piston rod thus regulated, causes syphoning to cease
before all the water has been exhausted from the cistern. Hence all gurgling
through rush of wind is avoided and the action is noiseless.
While syphoning is in progress the lower chamber "G" is supplied with water
from the down pipe through the whistle-lipped aperture "H," at the same time as
water in down pipe is flushing closet pan. The ventilating shaft "L" vents this
chamber during the process of filling. When syphoning ceases and the down pipe
empties itself, the lower chamber, discharges water through the outlet from lower
chamber into down pipe and acts as an after-flush to charge the closet pan of a
valve closet when applied thereto.
The advantages of the improvement are as follows.
A
The action is entirely noiseless. It can be fitted to valve closets and gives an
after-flush to charge the pan. It is an absolute water-waste preventer as water
cannot possibly escape without first passing up the cylinder and syphoning over.
The trigger pull which is placed outside the cistern is constructed as follows:-
An oblong plate of metal marked "N" slides in two "V"-shaped grooves.
pivot is fixed in the plate "N." A strip of metal marked "M" with a hooked
end to act as a catch is made capable of revolving on the pivot. A stop is placed
at a certain distance from top & bottom of sliding plate "N" to prevent its
moving too far. The action is as follows:-The hooked end of pull "M" engages
the lever "F." When pulled down, the pull "M" runs off and releases the
lever "F." A chain attached to weighted lever "K" raises the pull into original
position. The lever "F" is at liberty to return at its own speed and the pull "M"
can pass it in rising at any point without obstructing it.
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. A perforated hollow piston rod which is attached to a bucket with valves
and which passes through a stuffing box in a cylinder open at both ends; the
cylinder having a down pipe connected with it towards the top.
2. In connection with the afore-mentioned parts, a forked lever to raise the
hollow piston rod.
3. A trigger pull which releases and adjusts itself and which engages the said
forked lever.
4. The combination of a lower chamber with whistle-lipped aperture and outlet
from lower chamber into down pipe.
