Improvements in or relating to Apparatus for Applying Disinfectant
to W.C's, Dustbins, and other Places.
I, FREDERICK SIGISMUND SALBERG, of 23 Garlick Hill, Cannon Street, in the
City of London, Merchant, do hereby declare the nature of this invention to be
as follows:-
This invention relates to apparatus for applying disinfectant to w.c's, urinals,.
dustbins and other places and consists of a bellows or equivalent device for
automatically ejecting a quantity of the disinfecting agent, which is in the form of
powder, into the water to be delivered to the w.c. or other place or directly into the
lust-bin or equivalent.
Under this arrangement the bellows or ejecting device preferably comprises three
main chambers viz.--a lower one in which is moved a piston provided with a suitable
ncn-return valve, a middle one separated from the lower one by a diaphragm
having a non-return valve and an outlet branch at one side, and an upper one
divided from the middle one by a diaphragmn having one or more perforations to
allow a sufficient quantity of the disinfecting material with which this upper
chamber is charged at each operation of the apparatus to drop into the middle
chamber. The upper and lower chambers are closed by covers that of the
upper chamber being unperforated and that of the lower one perforated to provide
for the free access of air. The lower cover is also provided with a central aperture
and externally-screwed projection through which passes the rod connected with the
piston and by means of which projection and a nut screwed thereon the device may
he secured to a suitable support; or the projection and nut may be dispensed with
and the fixing effected in any other desired manner.
At the outer end of the before-mentioned outlet branch I provide a suitable
discharge nozzle and a screw or valve for regulating the effective size of the
opening thereof so as to admit of more or less of the disinfectant being discharged
at each operation.
The lower end of the piston rod which may be weighted or spring-controlled bears
upon or is connected with any operative part of the water-supply-- or flushing-
apparatus so that, in the case of flushing apparatus, the piston will descend at each
discharge of the apparatus and allow some of the disinfectant to fall from the upper
chamber into the middle chamber. When the flushing tank is being filled the
piston is pressed upwards and causes the disinfectant to be discharged from the
middle chamber, through the outlet nozzle into the tank where it mixes with
the water then being admitted, the water with this disinfectant mixed with it
being delivered to the w.c. or other place at the next discharging operation of
the apparatus.
The before-described device may be applied to an ordinary ball or equivalent
supply tank for storing up a quantity of liquid disinfectant, any desired quantity
of which may be discharged at will by manipulating a suitable valve or cock..
An arrangement such as this besides being applicable to w.c's, may also be applied
to sinks and other places.
The disinfecting material which I prefer to use is a mixture of boracic acid
and permanganate of potash in the proportion of say 800 grammes of the former
to 40 grammes of the latter

page_text: The before-described device may be applied to other articles or places than w.c's
and sinks for example I may use it for delivering any disinfecting agent in
powdered form and in a dry state into dust-bins the opening and closing of the lid
causing the operation of the piston and the consequent delivery of the powder into
the dust-bin.

Improvements in or relating to Apparatus for Applying Disinfectant
to W.C's, Dustbins, and other Places.
I, FREDERICK SIGISMUND SALBERG, of 23 Garlick Hill, Cannon Street, in the
City of London, Merchant, 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 invention relates to apparatus for applying disinfectant to w.c's, urinals,
dustbins, and other places and consists of a bellows or equivalent device for
automatically ejecting a quantity of the disinfecting agent, which is in the form of
powder, into the water to be delivered to the w.c. or other place or directly into
the dustbin or equivalent.
The invention will be best understood by reference to the accompanying drawing
which shows the apparatus in vertical section.
In the arrangement as shown in the drawing the bellows or ejecting device
preferably comprises three main chambers viz. a lower one A in which is moved
a piston B provided with a suitable non-return valve B', a middle one A' separated
from the lower chamber A by a diaphragm A2 having a non-return valve A³ and
an outlet branch A at one side, and an upper one A° divided from the middle
chamber A by a diaphragm A6 having one or more perforations A' to allow a
sufficient quantity of the disinfecting material with which this chamber A³ is
charged, at each operation of the apparatus to drop into the middle chamber A¹
The upper and lower chambers A and A respectively are closed by covers C and C¹,
that (C) of the upper chamber A being unperforated and that of the lower one
perforated as at ("to provide for the free access of air. The cover C¹ is also
provided with a central aperture (and externally--crewed projection (4 through
which passes the rod B connected with the piston B and by means of which
projection, and a nut (³ screwed thereon the device may be secured to a suitable
bar or other support D; or the projection C and nut ("* may be dispensed with
and the fixing effected in any other desired manner.
At the outer end of the outlet branch A' I provide a suitable discharge nozzle A"
and a screw or valve E for regulating the effective size of the opening thereof so
so as to admit of more or less of the disinfectant being discharged at each
operation.
The lower end of the piston rod B2 which may be weighted as shown at B³ or
spring-controlled bears upon or is connected with any operative part of the water-
supply- -or flushing-apparatus so that, in the case of flushing apparatus, the piston
will descend at each discharge of the apparatus and allow some of the disinfectant to
fall from the upper chamber into the middle chamber. In the drawing I have
represented the rod B2 as resting on the lever F which may be a ball or float lever.
When the flushing tank is being filled the piston B is pressed upwards and causes
the disinfectant to be discharged from the middle chamber A', through the outlet
nozzle A into the tank (not shown in the drawing) where it mixes with the water
then being admitted, the water with this disinfectant mixed with it being delivered

page_text: to the w.c. or other place at the next discharging operation of the apparatus; or
the piston B may be raised by the lever through which the flushing operation is
caused to take place under which circumstances the disinfectant would be introduced
into the water immediately before its delivery to the w.c. or other part or apparatus
to be flushed.
An
The before-described device may be applied to an ordinary bail or equivalent
supply tank for storing up a quantity of liquid disinfectant, any desired quantity of
which may be discharged at will by manipulating a suitable valve or cock.
arrangement such as this besides being applicable to w.c's may also be applied to
sinks and other places.
The disinfecting material which I prefer to use is a mixture of boracic acid
and permanganate of potash in the proportion of say 800 grammes of the former
to 40 grammes of the latter.
The before-described device may be applied to other articles or places than w.c's
and sinks for example I may use it for delivering any disinfecting agent in
powdered form and in a dry state into dustbins the opening and closing of the
lid causing the operation of the piston and the consequent delivery of the powder
into the dustbin.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. Disinfecting w.c's and other places or apparatus to which a flush of water is
intermittently delivered by a disinfectant in the form of powder automatically
mixed with the water prior to its delivery to the place or apparatus to be
disinfected.
2. Disinfecting w.c's and other places or apparatus to which a flush of water is
intermittently delivered by a disinfectant in the form of powder automatically
mixed with the water in the flushing or equivalent tank prior to its delivery to the
place or apparatus to be disinfected.
3. A device for ejecting disinfectant in the form of powder comprising three
chambers such as A A' and A' valve such as A³ and piston such as B substantially
as described and illustrated in the accompanying drawing.
4. In a device for ejecting disinfectant in the form of powder the combination
with three chambers such as A A' and A' of a regulating-screw or valve such as E
substantially as and for the purpose described and illustrated in the accompanying
drawing.
5. The combination and arrangement of parts constituting the complete apparatus
for applying disinfectant to w.c's and other places substantially as described and
illustrated in the accompanying drawing.
