Improvements in Waste Water Preventers.
We, RICHARD CHANTRY of 67, Brandon Street, Walworth in the County of
Surrey, and WILLIAM HENRY PETERS of 62 Pollock Road Walworth in the
County of Surrey, Zinc Workers, 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 object of this invention is to lock the ball or float valve in the waste water
supply cistern and at the same time automatically unlock the starting valve and
syphon tube so that when the lever is pulled the starting valve and syphon tube
are opened and this latter kept so until the cistern is quite empty.
According to this invention to the lever of the float or ball valve we attach a
toothed quadrant which actuates a tumbler, this tumbler consists of a tube having a
loose ball therein. The said tumbler actuates suitable mechanism for locking the
ball valve syphon valve and starting valve when the cistern is empty, but when the
cistern is full the lever can be pulled, thus starting the syphon but not before.
And in order that our said invention may be the better understood, we will
proceed to explain same with reference to accompanying sheet of drawings in which
Figure 1 represents a front elevation of the whole internal mechanism of this
apparatus in which the relative positions of the various parts are such as when the
cistern a is filled with water in which case the valve bat lower part of syphon
and the valve d are closed due to the pressure of water against them, but they are
not then locked, but both become so as the cistern empties.
The same letters denote the same parts in all the views also shown detached at
Figs. 2 and 3 shews front and side elevation respectively of toothed quadrant
pivotted at round which it rotates through a limited angle. Fig. 3 of this piece
shews two projecting parts g. g. which actuate the tumbler h. as hereafter described.
i. is a lever shewn detached in Figs. 4 and 5 of which Fig. 4 is a plan and Fig. 5 an
elevation.
To this lever is attached a projecting plate j. and the lever moves on a pivot k
when the arm w. is pressed downwards.
One extremity of this lever is pivotted to the connecting rod 7. and the other end
has a cord or chain m, attached.
The part shewn detached in Figures 6. 7 and 8 is a piece pivotted at n on to the
pivotted catch shewn detached in Figures 15 and 16 at e. Fig. 7 is a side
elevation. Fig. 6 an underside plan and Fig. 8 a top plan of same.
On one side shewn in Fig. 7 is a catch o. curved on side shewn in drawing.
The other side of this piece is so shaped as to allow it to rise or fall when the
projection p. on the tumbler h. acts on it at y. as hereinafter described.
The piece shewn detached in Figs. 9, 10 and 11 is also pivotted at f. Fig. 10 is
a front elevation, Figs. 9 and 11 two side elevations of same.
The projection r. shewn in Figs. 10 and 11 attached to the arm s. is arranged so
that the projection t. on the tumbler h. shall move the whole piece on pivot f. shewn
in these figures, u. shewn in Figs. 9 and 10 is a groove in which the catch v.
slides, was shewn in Fig. 11 is a recess in which the piece shewn in Figures 12, 13
and 14 moves and connected by the same pivot f. round which both parts move.
The arm x. shewn in Fig. 10 locks the lever described in Figs. 4 and 5 as hereafter
described when the cistern has become emptied and keeps it locked until filled
again.
The projection y. at extremity of arm x. Fig. 10 keeps the arm x on the
projecting plate j. by preventing the lever carrying that plate moving laterally
from underneath that arm.

page_text: The piece shewn detached in Figs. 12, 13 and 14 has two arms and a¹ and is
pivotted at f. 1 (Fig. 13) is a catch which when acted on by the under edge of
the recess shewn in Fig. 11 causes the whole part to turn round on pivot f. and
so brings the arm a' on to the upper side of projecting plate j. shewn in Figs. 4 & 5.
. is an arm the use of which will be shewn further on.
is a pivot attached to
the arm a¹ to which the rod is attached and actuated so as to lock and unlock
the syphon valve b. (see piece detached at Figs. 18 and 19).
The piece shewn detached in Figs. 15 and 16 is an arrangement for stopping or
holding the ball tumbler in the position shewn in Fig. 1. which is effected by the
hook . (Fig. 16) passing over the arm s. shewn detached in Fig. 10 and into the
groove u.
It is pivotted at e¹.
The piece shewn detached in Figs. 6, 7 and 8 is pivotted to it at n.
The piece shewn detached in Figs. 17, 18 and 19 consists of a valve b. a lever
pivotted at and a connecting rod d' pivotted to lever at g' and to the arm at c¹.
Having now described the various parts of the apparatus we will proceed to
describe how the locking and unlocking of the two valves is effected. The locking
of the valves is effected in the following manner.
The
They are unlocked when the cistern a. is full of water but as it becomes emptied
the float falls and the arm r¹ attached to it falls also and turns the toothed
quadrants and shewn detached at Fige. 2 and 3 pivotted at f. and 13 and the
tumbler . pivotted also at f. is actuated by 9. (Fig. 3) when after it has arrived
past the horizontal position the ball pe contained therein rolls to the other end than
that shewn in the drawing consequently giving a downward pressure to that end
of the tumbler when the projection p attached to tumbler pressing against
underneath side of the pivotted piece shewn in Fig. 7 at g. raises this piece and so
allows the arms. shewn also detached at Figs. 9, 10 and 11 to pass catch o.
projection then acts on arm s. pressing it forwards with itself when the arm ..
shewn also detached at Fig. 10 presses downwards on the upper side of lever also
shewn detached in Figs. 4 and 5 thus locking this lever and consequently locking
the valve d so that it cannot be opened by pulling the chain or cord m. until the
cistern has become filled again. At the same time that the valve d has become
locked, the valve . has become locked also by reason of the fact that the pivot c¹
having pressed down the connecting rod d the valve b. is raised which closes
syphon (see detached view Fig. 18) so that it cannot be unlocked by pulling down
the lever . before the cistern has filled again.
When the cistern a. is full both of the valves are unlocked and it can be emptied
by pulling down the chain or cord m. of lever which opens valves thus letting the
water out, the arm z. Fig. 13 pivotted at is forced behind catch o. thus preventing
the rush of water through syphon closing the valve b. when pressure is taken off
the lever in, but so long as the cistern is not full the valves b and d are locked and
cannot be opened by pulling down arm w. because so long as the cistern is not full
or only partially full the float has not risen sufficiently to cause the projection t.
on tumbler to act on r. shewn also on the piece detached at Fig. 10 to cause
lower edge of recess w¹ (shewn clearly in Fig. 11) to press on catch b' (shewn
clearly at Fig. 13) so as to force the arm a' on to the upper surface of the projecting
plate j. in order that j. can actuate it and consequently open the valve b. by raising
connecting rod d' as before described shewn also detached at Fig. 10. Also for
this reason the lever . is in the way of the lever i (shewn detached in Figs. 4 and 5)
so that the latter cannot be raised and consequently so that also the valve d. cannot
be raised.
The valves d and are locked when the cistern is empty and become unlocked in
the following manner.
As water fills the cistern the float rises with it and the arm attached to it
actuates the toothed quadrants pivotted at f. and land after the ball tumbler & has
arrived past the horizontal position the ball p therein falls to the end of tumbler
shewn in drawing Fig. 1. and the projection t. attached to tumbler presses on r. this

page_text: latter shewn detached also at Fig. 10 thus moving the whole of the part shewn
in Figs. 9, 10 and 11 round the pivot f. when the curved side of the projection on
the extremity of the arm s in Fig. 9 presses against the curved side of the catch o.
thus raising the whole of the part shewn in Figs. 6, 7 and 8 round pivot n. thus
allowing the part shewn also detached in Figs. 9, 10 and 11 to pass.
Whilst this is taking place the extremity of the arm s. presses upwards on the
underside of the part shewn also detached in Figs. 15 and 16 which is pivotted at e¹
thus raising it when the catch v. prevents the arm s. moving further and
consequently holds the ball tumbler in the position shewn in drawing Fig. 1.
The part shewn detached in Figs. 9, 10 and 11 is also held in the position shewn
in Fig. 1. and the lower edge of the recess w having pressed on the catch b' shewn
detached at Fig. 13 the whole of the piece shewn detached at Figs. 12 13 and 14
has also moved into the position shewn in Fig. 1. the arm a¹ resting on the upper
surface of projecting plate j. in which case the lever shewn also detached at
Figs. 4 and 5 is unlocked and consequently the two valves b and d are unlocked
also so that when the arm w. of lever is pulled down the valves open.
The object of the ball in tumbler is to give power to the tumbler to actuate the
parts which the projections t and p. press against.

Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements hereinbefore described for locking the ball valve or float
and at the same time automatically unlocking the starting valve and syphon tube,
all substantially as and for the purpose described.
