PROVISIONAL SPECIFICATION..
Improvements in Disinfecting Apparatus for Use in Water Closets,
Urinals, Lavatories, and the like.
I, VILLIERS BARRETT LENNARD of 78 Norroy Road Putney, in the County of
Surrey, Sanitary Engineer do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in the means of and apparatus for
disinfecting water-closets, urinals, lavatories, baths, public conveniences, drains and
the like, and has for object to ensure a regular and automatic introduction of
disinfecting agents into the water used at each flushing operation in its passage
from the cistern or reservoir to the pan or basin, and also to provide means for
regulating the quantity of disinfectant so used at any single operation.
With this object, in the case of a water closet I propose to utilise the down-flow
of water from the cistern or flush tank to the pan for the purpose of withdrawing
by syphonic action, the necessary supply of disinfecting fluid from a suitable holder
or containing-vessel arranged at any convenient position below the level of the
cistern or flush tank and connected by a bent pipe or tube with the down-pipe at
any desired point above the level of the containing vessel.
. I
In applying my invention to a urinal 1 may use the flow of water from the water
supply pipe for the purpose of withdrawing in a similar manner by syphonic action
the necessary supply of disinfecting fluid from the holder or containing vessel
which in such case is arranged at a convenient position below the level of the water
supply tank, a similar connecting pipe being employed between the holder and the
down pipe to that described in the case of a water closet.
In carrying out my invention I place the holder or container, which may be made
either of glass, earthenware or metal, and in any convenient form,-upon a shelf or
upon brackets secured to the inner face of the wall or partition of the closet or
urinal at any suitable position between the level of the cistern and the pab,
'or between the water supply pipe and the urinal. In the upper side or cover of the
container are formed two orifices, one, for charging it with fluid, being fitted with
a perforated screw stopper.or equivalent closing device. Through the other orifice
is passed the lower end of a bent pipe or tube of small diameter extending nearly
to the bottom of the container; the upper portion of this pipe being bent horizontally,
and connected at its end by a suitable union or joining-piece to the down-pipe, so as
to form communication between the latter and the container,
In. use, the screw stopper having been removed and the disinfectant poured into
the container, the orifice is securely closed.; when the flushing valve of the cistern
is opened the sudden rush of water through the down pipe exhausts the air from
the bent pipe, thereby producing syphonic action therein and causing the dis-
“infectant to flow through it from the container into the down pipe, by which it is
conveyed to the closet pan or to the urinal.
In order to permit of the regulating of the quantity of disinfectant passing out
of the container at each flushing operation, I provide a screw-down valve or
equivalent regulating device in the narrow pipe or tube, preferably at a short
distance above the point of its entrance into the container.

Improvements in Disinfecting Apparatus for Use in Water Closets,
Urinals, Lavatories, and the like.
I, VILLIERS BARRETT LENNARD, of 78 Norroy Road Putney in the County
of Surrey, 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:-
My invention relates to improvements in the means of and apparatus for
disinfecting water closets, urinals. lavatories, baths, public conveniences, drains and
the like, and has for object to ensure a regular and automatic introduction of
disinfecting agents into the water used at each flushing operation in its passage
from the cistern or reservoir to the pan or basin, and also to provide means for
regulating the quantity of disinfectant so used at any single operation.
To attain this object I employ the arrangement illustrated on the accompanying
drawings upon which
Figure 1 is a side view of my improved disinfecting apparatus,
Figure 2 being a section of the same.
Figure 3 is a plan of the same.
Figure 4, a side elevation shewing the application of the apparatus to a valve
closet.
In the case of a water closet,, as shewn on Figures 1 to 4, I propose to utilize
the down-flow of water from the cistern or flush-tank to the pan for the purpose
of withdrawing by syphonic action the necessary supply of disinfecting fluid from
a suitable holder or containing vessel A arranged at any convenient position below
the level of the cistern or flush tank, and connected by a pipe or tube B with
the down pipe Cat any desired point above the level of the containing
vessel A.
In applying my invention to a urinal I may use the flow of water from the
water supply pipe in a similar manner for withdrawing by syphonic action, the
necessary supply of disinfecting fluid from the holder or containing vessel which
in such case is arranged at a convenient position below level of the water-supply
tunk, a similar connecting pipe being employed between the holder A and down
pipe C to that described in the case of a water.closet.
As will be seen on Figures 1 and 2, I place the holder or container A, which
may be made either of glass, earthenware, or metal, and in any convenient form,
upon a shelf or upon brackets D, secured' to the inner face of the wall or partition
of the closet or urinal at any suitable position between the level of the cistern and
the pan, or between the water supply pipe and the urinal. In the upper side or
nover E of the container A, are formed two or more orifices; to the centre one, F.
is attached a tee-piece H, furnished at its upper end with a stopcock or stopper G,
through which the fluid is inserted into the container A. Or, I may attach the
tee-piece H direct on to the upper end of the vertical pipe, and I may also insert
an ordinary back valve in the horizontal pipe B to retain liquid therein, if desired.
From the ice-piece H descends one end of a pipe or tube B of small bore nearly
to the bottom of the container A, the pipe being continued from the side of the
tee-piece H in approximately a horizontal direction to the supply pipe C, to which
it is attached by means of a suitable union or joining-piece K, so as to form com-
munication between the supply pipe C and the container A. At or near the
junction of the horizontal part of the pipe B with the water supply pipe C, I
provide an air-cock I by means of which, the quantity of Buid drawn off at
each flushing, operation, can readily be regulated. When applied to a valve-
closet, as shewn on Figure 4, the container Å may conveniently be fixed upon the
aleset seat L.

page_text: When
In use the screw-stopper or cock G having been opened, and the disinfectant
poured into the container A, the screw-stopper or cock is securely closed.
the flushing valve of the cistern is opened the sudden rush of water through the
supply-pipe C exhausts the air from the pipe B thereby producing syphonic action
therein, and causing the disinfectant to flow through it from the container A into
the supply pipe C, by which it is conveyed to the closet-pan or to the urinal.
The openings M in cover E, serve for the admission of air to the container A,
during the withdrawal of fluid therefrom.
The quantity of disinfectant drawn out of the container A at each flushing can
be readily regulated by partly closing the air-oock I on pipe B.
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. Disinfecting apparatus consisting of a container A furnished at its upper end
with a perforated cover E, and screw-stopper or cock G, in combination with a
pipe B provided with an air-cock I, and extending from the lower portion of the
container to the water supply pipe C, for the purposes and as described.
2. Disinfecting apparatus constructed, combined and arranged substantially as
described and illustrated on the accompanying sheet of drawings.
