PROVISIONAL SPECIFICATION.
Improved Sanitary Arrangement for Automatically Disinfecting
Water Closets and the like places.
CHARLES LENI Machinist 377 Strand London do hereby declare the nature of
this invention to be as follows:
I provide a vessel that will hold about thirty ounces-glass for preference, as the
action can best be seen, and the time to replenish the disenfectant be more readily
ascertained.
In this glass vessel I deposit a disenfectant enclosed in a cone, or other shaped
metal receptacle, perforated at, or near the lower end. This glass vessel has an
opening at the lower end, for the purpose of attaching an elastic tube; and from
this opening I carry this elastic tube of about 3 of an inch diameter, and 12 inches
long, to a tapered screw nipple. This nipple I screw into the flushing pipe, down
which, when the water descends, a portion will pass through the nipple and along
the elastic tube into the glass vessel, the tube.to be kept in a horizontal position.
The necessary quantity of water required to pass into the glass vessel-and this
requires a different quantity according to circumstances-I provide for by a simple
contrivance as follows:-
The glass vessel has a large opening at the top, which is fitted with an air tight
metal cap with one perforation.
On the top of the beforementioned cap is fixed by means of a screw, a revolving
disc with a number of holes of different sizes placed a certain distance from the
centre. One or other of these holes in the disc is intended to come immediately
over the perforation in the cap, to regulate the quantity of water admitted from
the flushing pipe to the glass vessel-(I do not confine myself to any one system of
venting; the one here mentioned cannot be easily interfered with) the quantity of
water allowed to flow into the glass vessel being an important consideration. To
regulate this quantity, the disc must be moved so that one or other of the holes is
placed immediately over the small hole in the cap of the glass vessel, thereby
admitting air in greater or smaller degree. The larger the hole used.in the disc,
the larger the quantity of water admitted, and the smaller, the inverse.
As the pressure of water ceases in the flushing pipe, the required quantity of the
dissolved disenfectant will leave the glass vessel and mix with the water in the pan
and trap.
An important feature in this apparatus is that as water closets are, in some
establishments, used, say for example, every quarter of an hour, others may not be
used more than six times in the twenty four hours; therefore the water closet that
is used every quarter of an hour requires the water to flow into the glass vessel to
a greater extent, so as to carry off the required quantity of the dissolved
disenfectant.
To prevent the disenfecting material from being wasted, there is placed at the
bottom of the glass vessel a metal stand, to keep the disenfectant from contact with
the water when not required.

Water Closets and the like places.
I CHARLES LENI of 377 Strand London in the County of Middlesex 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 :--
This my invention relates to an improved sanitary arrangement for automatically
disinfecting water closets and the like places and my invention consists in the
combination with a flushing apparatus of a vessel adapted to discharge into the
closet basin or other place to be disinfected.
In carrying out my invention I provide a vessel of a suitable size (preferably of
glass as by this material the action can be seen and the time to recharge the vessel
can be readily ascertained). Within the said vessel I place a disinfectant enclosed
in a conical or other shaped metal or other receptacle perforated at or near the
lower end.
The said vessel has an opening at the lower end preferably at the side for the
purpose of attaching a tube the said tube being connected at the other end to a
nipple which is screwed or otherwise fixed in the flushing pipe the end of the said
nipple entering the flushing pipe and having an aperture therein for the purpose of
intercepting a portion of the water descending the said flushing pipe the said
intercepted volume passing through the said tube and entering the vessel containing
the disinfectant.
I regulate the quantity of water entering the said vessel by means of the
following simple device. The said vessel is fitted with an airtight fitting cap or
cover having a perforation formed therethrough, on the top of the said cap or cover
being adjustably secured a metal plate having a number of holes therein of
different sizes any one of which can be made to register at will with the opening in
the said cover.
The quantity of water entering the said vessel may therefore be regulated at
will by causing a large or small hole to register with the hole through the cap and
thus by retarding the escape of the air from the said vessel the quantity admitted
being increased as a larger hole is presented for the escape of the air & vice versa.
As the flow of water through the flushing pipe causes the quantity of water
which has entered the vessel will become charged with the disinfectant contained
therein and the solution thus formed is then allowed to escape into the trap and
drain.
In order that my invention may be more readily understood reference is made to
the accompanying drawings in which I have represented an apparatus constructed
in accordance with my invention and in which
Fig. 1 shews a front elevation of the disinfecting apparatus
Figs. 2 and 3 being details of the same hereinafter referred to.
A is the flushing pipe leading from the flushing tank, B is a nipple inserted in
the said pipe A. being secured by a nut b, C is a tube leading from said nipple to a
tap or nozzle c which is screwed or otherwise fixed at the lower end of the vessel D
containing the disinfectant.
A tape is preferably placed in the tube C to control the supply of the
disinfectant to the closet pan or other object but the said tap may be omitted if
desired.
The vessel D is preferably of glass and is supported upon a bracket or shelf d
and the said vessel has inserted therein a cone F preferably of metal in which the
disinfectant employed is placed.
The metal cone has perforations therein to allow the water entering the vessel

page_text: to enter the said cone and dissolve the disinfectant contained forming a solution of
the same.
The action of the apparatus is as follows:-
The water descending the flushing pipe A passes the nipple B and a certain
volume enters the tube C through the opening a in the said nipple (which is shewn
more clearly in Fig. 3). The water passing through the said tube enters the
vessel D) the tap in the said tube being open the quantity being governed by the
escape of the air through the holes h in the plate H as before described. As soon
as the volume of water in the flushing tank has passed down the flushing pipe A.
the saturated solution of the disinfectant contained in the vessel D will return
through the tube C and be discharged through the orifice a into the flushing pipe A
by which it passes into the pan and trap of the drain.
The vessel D is provided with a cover G which is airtight and is preferably
screwed upon the top of the said vessel. An opening g is formed through the said
cover G (as is shewn in the plan view Fig. 2) the said opening being covered by a
plate H the said plate being fastened on the top of said cover by means of a screw
or other fastening so as to allow its adjustment.
As it is sometimes undesirable to allow to allow the disinfectant to remain in
the pan, discolouring the latter, besides having a disagreeable appearance I may
provide a tape in the pipe C in which case the operation is as follows.
The first flushing will cause a certain quantity of water to enter the vessel D,
the tape is then shut off. Previous to again flushing the closet the tape is opened
and the disinfectant from the vessel D passes into the pan and trap, the flushing
valve being then opened, the water in the cistern will clear the disinfectant from
the pan, and also recharge the vessel D upon which the tape is again closed ready
for the next flush.
An important feature in this apparatus is that as water closets are, in some
establishments, used, say, for example, every quarter of an hour, others may not be
used more than 6 times in twenty four hours. By adjusting the plate H, in the
former case, I may allow a greater volume of water to enter the vessel D so that
more of the disinfectant may be dissolved at each flushing.
The tape may be omitted if desired, and I may also modify the arrangement for
permitting the escape of the air from the vessel Ď.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what I
claim is,
1. In an apparatus for disinfecting water closets or the like the combination with
the flushing pipe of a vessel connected at its lower end to the flushing pipe by a
tube or perforated chamber in the said vessel for containing the disinfectant-an
adjustable valve for controlling the admission and emission of the disinfectant to
said vessel, the whole being constructed, arranged and operating substantially as
described and illustrated.
2. In an apparatus for disinfecting water closets or the like the combination with
the flushing pipe of a vessel connected at its lower end by a tube to the said
flushing pipe, a tap or valve for opening and closing said tube, a perforated chamber
within the said vessel for containing the disinfectant, an adjustable valve for
controlling the admission and emission of the disinfectant to said vessel, the whole
being constructed arranged and operating substantially as described and
illustrated.
