PROVISIONAL SPECIFICATION.
Improvements in Discharge Apparatus of Water Closet or other
Cisterns.
1, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of
Renfrew, North Britain, Sanitary Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention has for its object to improve the construction of discharge
apparatus of water-closet or other cisterns, and to diminish or prevent noise and
waste of water.
In carrying out my invention according to one modification the cistern is made
of a size to contain the water for each flushing, and is emptied by means of an
ordinary two-legged siphon. At or near the lower end of the ascending leg of the
siphon there is formed an enlargement, as in some existing siphons, and through a
hole in the side of this enlargement there projects into the interior of the leg a
nozzle on the end of a pipe leading from a small chamber in the cistern below the
water level. In this chamber there fits loosely a disk connected to the lever
worked by the closet handle; and on pulling the handle the disk forces the water
in the small chamber through the nozzle in the form of a jet which starts the
siphonage.
According to a second modification the entrance end of the ascending leg of the
siphon extends down into, or may be made in a piece with, a small well or pocket
formed in the bottom of the cistern and the nozzle on the end of the pipe leading
from the small chamber is directed so as to cause the jet of water to be directed
into this well and thus start the siphonage.
Or the small chamber and nozzle may be dispensed with the disk attached to
the closet handle, in this modification working loosely in a part of the descending
or long leg of the siphon. On pulling the handle the disk is depressed and starts
the siphonage and in its lowest position the disk is in an enlarged part of the
descending leg which enlargement allows the water to pass freely away round
the disk.

Improvements in Discharge Apparatus of Water Closet or other
Cisterns.
I, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of
Renfrew, North Britain, 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, that is to say :—
My said invention has for its object to improve the construction of discharge
apparatus of watercloset or other cisterns, and to diminish or prevent noise and
waste of water.

page_text: Five modifications of apparatus, as made according to my invention are shown in
vertical section on an accompanying sheet of explanatory drawings. In these
drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
In carrying out my invention according to the modifications shown in the
drawings the cistern. A, is made of a size to contain the water for each flushing,
and is emptied by means of an ordinary two-legged siphon, B. In the modifi-
cations shown in Figures, 1, 2, and 3, at or near the lower end of the ascending
leg of the siphon, B, there is formed an enlargement, C, as in some existing siphons.
Through a hole in the side of this enlargement, C, there projects (as shown in
Figures, 1, and 2) into the interior of the leg a nozzle on the end of a pipe, D,
leading from a small chamber, E, in the cistern, A, below the water level. Instead
of the pipe, D, projecting into the ascending leg of the siphon, B, the ascending
leg is in the modification shown in Figure, 3, made with a branch, G, to commu-
nicate with the inside of the chamber, E. In the chamber, E, there fits loosely a
disk, H, connected to the lever, J, worked by the closet handle, K; and on pulling
the handle the disk forces the water in the small chamber through the nozzle
pipe, D, or branch, G, in the form of a jet or otherwise which starts the siphonage.
According to the modification shown in Figure, 4, the entrance end of the
ascending leg of the siphon, B, extends down into, or may be made in a piece with,
a small well or pocket, L, formed in the bottom of the cistern, A, and the nozzle, D,
from the small chamber, E, is directed so as to cause the jet of water to be directed
into this well and thus start the siphonage.
In the modification shown in Figure, 5, the small chamber, E, and nozzle, D,
may be dispensed with, the disk, H, attached to the closet handle, K, working
loosely in a part of the descending or long leg of the siphon, B. On pulling the
handle, K, the disk, H, is depressed and starts the siphonage, and in its lowest
position, the disk is in an enlarged part, M, of the descending leg, which
enlargement allows the water to pass freely away round the disk.
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 discharge apparatus of watercloset or other cisterns, a small chamber
communicating with the inside of the ascending leg of the siphon, and containing
a disk operated by the closet handle lever, substantially as and for the purposes
hereinbefore described, and as shown in Figures, 1, 2, and 3, of the accompanying
drawings.
2. In discharge apparatus of watercloset or other cisterns a small chamber
having a nozzle projecting into a pocket in the cistern, into which pocket the
ascending leg of the siphon also dips, the said cistern containing a disk operated
by the closet handle lever substantially as and for the purposes herein before
described and as shown in Figure, 4, of the accompanying drawings.
3. In discharge apparatus of watercloset or other cisterns, a disk, in the
descending or long leg of the siphon, worked by the closet handle lever, and which
in its lowest position, is in an enlarged part of the descending leg of the siphon
substantially as and for the purposes herein before described and as shown in
Figure, 5, of the accompanying drawings.
Dated this Fifth day of November 1895.
