AN IMPROVED WATER WASTE PREVENTER AND AFTER FLUSH COMBINED FOR WATER CLOSETS and
Year: 1884

page_text: I HERBERT TROTT Engineer of. 75 High St. Battersea in the County of Surrey
S.W. do hereby declare the nature of above Invention for AN IMPROVED WATER
WASTE PREVENTER AND AFTER FLUSH COMBINED FOR WATER CLOSETS and in
what manner the same is to be performed; to be particularly described and
ascertained in and by the following statement :-
:
The first part of the Invention relates to the way of forming the vessel A
Fig. 1 & 2 of the accompanying Drawings with a bottom valve B or a hinged
drop vessel underneath water cisterns or tanks, with resting studs at sides which
vessel holds its full quantity of after flush water required for water closets pans
or containers after the handle of water closet is let down.
2nd Part of the Invention relates to the novel way of raiseing the after flush
vessel A that is actuated, by a lever with a galvanized iron down rod or chain C
attached to bottom valve B, through centre of cistern valve pipe guide D.
3rd Part of Invention relates to the slideing action of after flush. vessel A. on
lower end of cistern valve pipe guide D, and is so constructed that when handle of
cistern lever is pulled the down rod or chain C. closes bottom valve B first of
vessel A, raiseing same which slides up outside of guide D of upper valve F to
stationary collar E, then it takes the weight of cistern valve F, and opens same,
and lets through the full quantity of water to w.c. which underneath vessel A
quickly catches its full quantity of water required for the after flush, and retains
same until handle of w.c. is let down. When the handle is released the valve F.
in cistern, closes. First then the bottom valve rod c allows after flush vessel A to
slide down pipe guide D and rests on studs P, an outer caseing G: remains stationary
leaving cistern valve F free, then bottom valve rod c, drops little lower, and opens
valve B, then the full after flush water follows. The interval between collar E
and resting studs P allows the first flush to escape.
4th Part of Invention relates to the novel way of fixing the outer caseing G
underneath water cistern or a tank that covers the after flush vessel A, with a
ventilating pipe attached. Also vessel A is very easely got at the outer caseing G
being moveable on pin N fixed on outside rim of bottom plate H attached to
cistern valve F. When bottom union of outlet pipe is unscrewed; the outer caseing G
will turn round on pin N and released, same time leaving vessel A suspended on
down rod C. On drawing pin K top of down rod C, can be taken out at bottom
with the vessel A complete. Also by unscrewing bolts 4 Fig. 2 the cistern valve F

can be seen to if necessary, without disturbing cistern or any main joints.
The cistern valve F Fig. 2, with rim bottom H attached, and after flush vessel A,
guide D and rod C. complete, with outer caseing can be fixed underneath any large
cistern or tank over w.c. by cutting hole through bottom of tank, to admit of
valve F then screwed up by the bolts L, which does away with separate cisterns,
were water is charged by meter.
5th Improvement relates to the way of fixing the centre down rod, or chain C
stationary on top of after flush vessel A. Fig. 2, leaving the bottom valve M, to
work independantly, so that when vessel A is at rest, the bottom valve M, is open
inside of vessel A that is raised, by the action of resting on cross bar O, attached
to outer caseing G. When vessel A is raised, the valve M closes first by its own
weight, then top of vessel A catches bottom of pipe guide D, and opens valve F. of
cistern or tank Fig. 2.
Lastly. I further make the after flush vessel A any shape and size to suite any
position that is neccesary. Also the lever is made longer, with a drop loop at end
to catch the ball valve lever of inlet, when lever of cistern is pulled down, that
shut's off the inlet water valve to cistern and makes it a perfect water waste
preventer with an overflow pipe at side. See Fig. 1 & 2
Also I use the bottom vessel A, inside of cistern, resting on three upright pillars
over top of cistern valve-F, and useing top of inner cistern valve F, to close the
inner vessel valve B when the lever is pulled down, which vessel is raised same
time from the upright pillars cutting off a second flush out. On release of handle
the cistern valve F closes first, and open the inner vessel valve B allowing the
cistern to be recharged.
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 To a after flush vessel A with a bottom valve B, and resting studs or
brackets at sides F Fig. 1 & 2.
2nd The way of raiseing the after flush vessel A. by a down rod or chain C from
end of pull down lever the other end of down rod is attached to cover of bottom
valve B working through cistern valve pipe guide D.
3rd To the slideing action of after flush vessel A on the lower end of down.pipe
guide D underneath centre of cistern valve F Fig. 1.
4th The way of fixing centre down rod or chain C stationary on top of vessel A
in Fig. 2 leaving bottom valve M. to work indepentantly that is raised by coming
in contact with stationary cross bar O which weight of valve closes, when vessel A
is raised.
5th The moveable outer caseing or cover over after flush vessel A with ventilating
pipe attached, that works outside of valve flange rim H, or bayonet joint to release
same when lower union is unscrewed Fig. 1-2.
6th A cistern valve with wide flange plate and deep rim H Fig. 2 also pipe guide
fastened through centre of valve F carried to the top of cistern, & below valve,
acting as slide guide for after flush vessel A. to work on, with a collar E to adjust
the length of slide to vessel A that raises the cistern valve cover F, Fig. 1.
