Improved Automatic Machine for Distributing Liquid Disinfectants
into Flushing Cisterns of Water Closets and Urinals, and for
other Purposes.
WILLIAM DAVIS Engineer Stock Exchange New Court Throgmorton Street
London E.C., and THOMAS JAMES TURNER Clerk of Works Stock Exchange New
Court Throgmorton Street London E.C. 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 :-
This machine is made of copper, brass or any other suitable material and has for
its object the distribution automatically of liquid discnfectants in such quantities as
desired, or required into the water in flushing cisterns to water closets and urinals
it can also be adapted to water carts etc. by being made a suitable size, it is so con-
structed as to be either portable or permanent in fixing. And is so arranged that one
machine is adapted to supply any single flushing cistern being increased in size
according to size of flushing cistern. In cases of a number, or sories of flushing
cisterns, in the same room, one tank sufficiently large to contain disenfectant required,
would he fixed in a suitable place and connected to machine in each flushing cistern
by means of a suitable sized lead or other pipe carried from tank longitudinally over
and above the tops of flushing cisterns, and a short piece of lead or other pipe, con-
nected to longitudinal pipe, and carried down and connected to tube, or pipe of machine,
a suitable distance above regulating cock of machine, by means of union cap and
lining, and dispensing with tank Das shown on Fig. 1 of drawings left with the
provisional specification.
The construction of the machine is as follows.
The machine is made a suitable size for any flushing cistern, or water cart etc., with
a dome, or square, or other shaped tank for holding the liquid disenfectant, in such
quantity as required, on top of tank is fitted a brass cap, screwed on so as to be easily
removable and under cap tank is perforated large enough to allow the disenfectant to
be poured in, near this cap is soldered or screwed into top of tank a small. vent cock
to allow sufficient air to pass into tank to ensure a free flow of disenfectant, the under-
side or bottom of tank is made to rest on top edge of flushing cistern, or can be fixed
any height required, above flushing cisterns, by lengthening pipe or tube from tank,
in cases of single flushing cisterns. From bottom of tank is carried a V shaped
hollow funnel, or outlet, ending in and connected to a piece of copper or brass tube
or pipe, or other suitable material, on top of V shaped funnel where same is connected
to bottom of tank, is placed a fine perforated grating entirely covering outlet, the tube
or pipe connected. to the bottom end of V, shaped funuel is carried down into flushing

page_text: cistern, within a suitable distance of the bottom, and terminates in a circular pointed
perforated nipple, screwed on to end of tube or pipe, so as to be easily removable, there
is also a small brass cock fitted on to tube near to V shaped funnel from tank, this
cock is to regulate the flow of liquid disenfectant from fank to flushing cistern, a
small raised washer or flange is made on tube from tank, a suitable distance from
regulating cock to prevent drum or float from falling off tube.
A circular hollow drum or float, made of sheet copper, brass, or other suitable
material, is fitted with a brass or copper tube or pipe, passing through contre from
end to end and connected to drum or float, and projecting a suitable distance each
end, this tube or pipe is large enough to slide easily over the pipe from tank and also
to clear washer or flange, on pipe from fank, on top end of tube passing through float
and connected to same, is screwed a brass cap, easily removable, this cap is perforated
with a hole large enough to slide casily over tube from tank, above washer or flange,
this
cap is dropped over tube on to washer and again screwed on to pipe or tube of
float, the bottom end of tube projecting from float is also fitted with a brass or other
cap screwed on and easily removable, and inside this cap is fitted a piece of india
rubber or other suitable material, a short distance above this cap soveral small holos
aro made in outer tube or pipe (of float) to allow disonfectant to pass out.
.
Having thus indicated the nature of our invention and shown in what manner the
same is to be carried into effect, we now proceed to describe the invention more
particularly, reference being made to drawings left with the provisional specification.
The drawing Fig. 1, is the elevation of the machine for single flushing cisterns,
shown with domed shaped tank 1), which can be enlarged to any size, or altered in
shape, for water carts, etc., A, is the rising and falling drum or float working on
tube, 1, the float here as on enlarged section on Fig. 2, is shown in action shutting off
flow of liquid disenfectant, 1 is tube passing through tube in drum, or float, and
terminating in perforated nipple screwed on to end of tube C, C, on Fig. 2, and as
shown at d, d, on Fig. 2, G, and H, are removable caps, screwed on, H, being pro-
vided inside bottom with india rubber washer a. a, are outlets for liquid, F, is
regulating cock, E, is V shaped funnel, on top, inside tank D, of which is fixed
perforated grating, B, is vent cock, and the removable cap for putting in the
disenfectant.
The drawing Fig. 2 is an enlarged section of float A, on Fig. 1, C, C, shows inner
tube or pipe from tank passing through drum, or float, and e, e, is the raised
flange, or washer, which prevents the cap B, B, from slipping off the tube C, C,
d, d, is the perforated (sue b) nipple. screwed on so that it can be easily taken off
to clean tube if required, b, is outlet in end of nipple, D, D, is section of drum or
Hont A, on Fig. 1. f,, is screwed end of tube passing through centre of and con-
nected to drum or float D, D, B, B, is screwed on to ff, so as to be easily removable,
a, a, is bottom end of tube passing through and connected to drum or float D, D,
E, E is bottom cap screwed on end of tube and easily removable, C, C, shows india
rubber washer, fitted into cap, and close up to end of nipple and in action
stopping flow of liquid, F, F are the outlets for liquid in outer tube connected to drum
or float.
It will be seen that when the drum or float falls so that the cap B, B, rests on
washer or flange e, e, (when flushing cistern is empty) the liquid disenfectant will flow
out of tank through C, C, at b, and through holes F, F, in outer tube or pipe, into
flushing cistern, until again closed. by water in cistern rising and lifting up float, when
disenfectant is shut off until flushing cistern is again emptied. The amount of
disenfectant required for each flush of cistern, from falling and again rising of drum
or flout, can be regulated by cock F, on Fig. 1.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
•
That this machine is self acting and by the method of construction is made to be

page_text: either portable, or permanent in fixing, and will automatically discharge the quantity
of liquid disenfectant required.
The machine is designed so as to be easily taken apart, for cleaning and other
purposes by any unskilled person, and easily put together again.
When once filled and placed in action requires no further attention, and can be
made to work in any kind of flushing cistern, or water cart, as herein before
described and illustrated by Figs. 1 and 2 of drawings left with the provisional
specification.
