Improvements in Arrangements and Apparatus for Supplying
Disinfectants to Urinals.
I, OSWALD BROOKE, of the Junior Constitutional Club, London, S.W. in.
the County of Middlesex, Gentleman, do hereby declare the nature of the said.
invention, to be as follows:-
My invention relates to apparatus and arrangements for supplying disinfectant
fluid or powder to urinals, so that a small quantity of such disinfectant will be
delivered to each urinal or to one or more if several are used adjoining each other;
automatically or otherwise, and for this purpose according to my present invention,
I apply a bucket wheel (or one or more of them) similar to that described in an
application by myself for a Patent No. 19,950 of 1890, for supplying any suitable.
disinfectant liquid to water closets.
The said bucket wheel consists of a wheel having a series of small buckets
carried on its periphery which wheel is rotated step by step, in a small cistern.
containing the disinfectant which the buckets discharge into a receiver from which
it is conveyed away to the pan of the closet.
-
By my present invention one or more of the bucket wheels and cisterns are used
and the disinfectant discharged is conveyed by pipes or channels to that point of
the urinal where required.
The bucket wheel is or may be rotated by the opening or closing or both opening
and closing of the door leading to the urinal or urinals, or it is or may be actuated
from a platform hinged or arranged so as to be lifted and depressed; that is lifted:
by a spring or weight, and depressed by the weight of the user stepping upon the
hinged platform, the movement thus obtained being conveyed by suitable connections
to the lever having the ratchet pawl for rotating the bucket wheel.
In urinals which are flushed by water, either automatically when the user steps.
upon a hinged platform or presses upon a "push" that opens a water valve or
otherwise, the same movement one way is or may be arranged to supply the
flushing water and the reverse movement the disinfectant according to my
invention.
There is or may be a separate bucket wheel and small cistern for each urinal,
or when several urinals are placed adjoining each other, one small cistern may be:
used for them, such cistern having as many separate bucket wheels as there are:
urinals, each bucket wheel discharging into a separate receiver communicating
with its urinal.
Or if desired there may be only one bucket wheel and the discharge from it may
be automatically directed into the pipe leading to the urinal from which the
actuating movement is transmitted.
In using the bucket wheel ford ischarging disinfectant in powder, the buckets
are or may be made to tilt when they attain their highest position, or pistons or
movable bottoms to the buckets are or may be used, on levers, actuated by a
tationary cam surface, which levers will receive movement at their highest position
o discharge the powder.
Or other modifications of the wheel or arrangements are or may be used for
lisinfectant in powder.
Dated this Fifth day of September 1891.

Improvements in Arrangements and Apparatus. for. Supplying
Disinfectants to Urinals.
I, OSWALD BROOKE, of the Junior Constitutional Club, London, S.W. in
the County of Middlesex, Gentleman, do hereby declare the mature of this
invention and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to apparatus and arrangements for supplying disinfectant
fluid to urinals, so that a small quantity of such disinfectant will be delivered to
each urinal or to one or more if several are used adjoining each other automatically
or otherwise, and for this purpose according to my present invention, I apply a
bucket wheel (or one or more of them) similar to that described in the Complete
Specification of a Patent No. 19,950 of 1890, granted to me, for supplying any
suitable disinfectant liquid to water closets.
The said bucket wheel consists of a wheel having a series of small buckets
carried on its periphery which wheel is rotated step by step in a small cistern
containing the disinfectant which the buckets discharge into a receiver from which
it is conveyed away to the pan of the closet.
By my present invention one or more of the bucket wheels and cisterns are used
and the disinfectant discharged is conveyed by pipes or channels to that point of
the urinal where required.
The bucket wheel is or may be rotated by the opening or closing or both opening
and closing the door leading to the urinal or urinals, or it is or may be actuated
from a platform hinged or arranged so as to be lifted and depressed, that is, lifted
by a spring or weight, and depressed by the weight of the user stepping upon the
hinged platform, the movement thus obtained being conveyed by suitable
connections to the lever having the ratchet pawl for rotating the bucket wheel.
In urinals which are flushed by water, either automatically when the user steps
upon a hinged platform or presses upon a push that opens a water valve or
otherwise, the same movement one way is or may be arranged to supply the
flushing water and the reverse movement the disinfectant according to my
invention.
There is or may be a separate bucket wheel and small cistern for each urinal, or
when several urinals are placed adjoining each other, one small cistern may be used
for them, such cistern having as many separate bucket wheels as there are urinals,
or one broad bucket wheel with divided buckets each bucket wheel or division of
bucket discharging into a separate receiver communicating with its urinal.
Fig. 1 is a front elevation, the cistern for the bucket wheel and the water valve
being shown in section, and Fig. 2 is a side sectional elevation of the bucket wheel,
cistern and other parts, and an outside elevation of the water valve.
The bucket wheel and cistern may be arranged as explained in my aforesaid
Specification No. 19,950 of 1890, that is to say, the ratchet teeth may be formed
on the bucket wheel or may be on a wheel separate from it and secured on the
shaft for the bucket wheel.
The trough to receive the contents of the buckets when discharged and the pipe
or channel from it may be arranged in any convenient manner.
The ratchet wheel may be actuated by a pawl jointed on an arm oscillating on
the axis of the bucket wheel, or it may be jointed to an arm oscillating on any other
fulcrum, suitably arranged.
In Figs. 1 and 2, the cistern a, is supposed to form part of a plate a¹, which
carries the fulcrum 6, of a three armed lever b, and a water valve c, so that one
fixing to the wall or other support will answer for all the parts, though the cistern,
fulcrum of the lever b, and water valve c, may be separately attached.
In Figs. 1 and 2, a, is the cistern for disinfectant fluid; a', the bucket wheel,

page_text: having buckets arranged as explained in my said Specification No. 19,950 of 1890,
to discharge into a trough a³, which may be attached to the upper end of a pipe a*,.
the lower end of which is screwed into the bottom of the cistern a.
d', is a pawl jointed on a stud, projecting from the side of an arm 6³, the
studd, passes through a slot as, in the side of the cistern.
e, is a retaining pawl on a stud secured in the side of the cistern; a', is the lid of
the cistern.
The arm 62, is one of a three armed lever b, ou a fulcrum stud b¹, secured in the
plate a', cast or otherwise attached to the cistern.
One arm of the lever b, has a weight b, upon it sufficient to lift the hinged
platform hereinafter referred to, and actuate the bucket wheel a³.
The short arm of the three armed lever b, is connected by a wire chain or other
attachment, with the hinged platform f.
This short arm of the lever b, also acts or may act upon the stem of the water
valve c.. which is or may be secured to the plate a¹.
This water valve c, is formed by a cone valve c', having a stem, passing
through a packing gland.
It will be closed when at liberty by the pressure of the water or its closing may
be assisted by a spring c³.
The inlet for water is at the branch c, and its outlet at the branch c³.
Any other ordinary and suitable valve or cock may be used for the water and
arranged to be actuated by the lever b.
9,
The water passes from the valve c, by the pipe c', to the pan or receiver of the
urinal which may be of any ordinary form and construction.
g', is the outlet branch from the pan g, to the sewer.
h, are the two sides forming the stall for the urinal.
fis a hinged platform for actuating the three armed lever, b.
The side sectional elevation of this hinged platform is shown by Fig. 3, and a
plan view of it by Fig. 4.
There is a board, which forms the base of the hinged platform f, which has a
front, and two sides, which carry the pivots of a flat bar, rounded at its two
ends which form the pivots f³.
To this bar f, the platform f, is secured by bolts f®.
The hinged platform, is of any desired extent, and from one side of it an
arm, extends to which the wire, is attached (which can be readily unhooked
or detached) that actuates the three armed lever b.
In Figs. 1 and 3 the hinged platform, is shown depressed and its underside is
then resting upon a support, upon the base board f
Any desired length of movement may be given.
The dotted line f*, Fig. 3 shows the position of the upper surface of the
platform, when at its highest position.
This binged platform may be constructed in any other convenient manner, its
front edge forms a step of about three inches high above the floor, but it may be
arranged to come on a level with the floor.
As shown and arranged it is applicable to existing urinals without alteration,
and can be readily removed when the floor below is to be washed, and as readily
replaced.
When the hinged platform is stepped upon, it is depressed and the three armed
lever is brought into the position shown in Fig. 1.
The pawl d', by the movement has been drawn back over the teeth of the
ratchett, ready to rotate it, and the bucket wheel, by its reverse movement, the
water valve c, has also been opened so that water begins to flow to flush the pan g,
then the moment the user steps from the platform, the weighted end (6º) of the
three armed lever b, descends (it is heavy enough to lift the platform and actuate the
ratchet pawl and bucket wheel) until its weighted arm comes against a stop u³, on
the plate a', the movement allows the water valve c, to shut, and rotates the ratchet
and bucket wheel, and causes it to discharge disinfectant into the trough a³, from

page_text: and enters
This is the action I prefer, but if desired, by reversing the bucket wheel a², its
ratchet pawl d, retaining pawl e, and its arm 6, the discharge of disinfectant may
be made to take place when the water valve c, is opened.
which it descends to the pipe a', to the water pipe *, below the valve c,
the pan of the urinal «.
A hinged platform arrangement of urinal, similar to that shown by Fig. 1 is to
be preferred as one most free from offensive smells.
There are arrangements of urinals flushed with water by a valve opened by
pushing a button, which is or may be pressed upon by the user, but is frequently
not used as it ought to be such an arrangement is illustrated by Fig. 5 (in which h,
are the stall divisions and g, the pan) except that the stem (c) of the water
valve of ordinary construction is turned to one side instead of being directly in
front.
Instead of the push being pressed in directly by the user, it is opened by one
arm, of a lever c', on a fulcrum at c³, this lever being actuated by pressing down
the knob or handle c, to which handle, one end of a wire chain or other
connection j, is secured to it, the other end of which is attached to the short arm
of a three armed lever b, which operates upon a similar arrangement of bucket
wheel cistern and mechanism, to that illustrated by Figs. 1 and 2, the fluid disin-
fectant being conveyed from the cistern by a pipe a, to the pipe c', for flushing
the pan 9, of the urinal below the water valve c.
When the water valve r, is opened the pawl d, is brought into the position to
move the bucket wheel, and when the handle c, is released the water valve shuts
and the disinfectant is discharged.
C,
If desired the disinfectant may be discharged when the water valve c, is opened
as above explained in reference to Fig. 1.
Urinals may have disinfectant supplied to them according to my invention, by
a bucket wheel and cistern and the opening or closing of a door leading to a
urinal, as illustrated by Figs. 6 and 7 respectively, a back and edge elevation of a
door supposed to be automatically closed by a spring or other means.
In such case there is or may be an arm k, attached to the upper frame of the
door k, this arm k', projecting above the door frame where there is a pulley **, on
a vertical axis carried in any convenient manner.
and
A chain, wire or other flexible connection ³, is attached to the arm k¹,
passes partly round the pulley, and its other end is connected to the pawl lever b³,
for working the ratchet of the bucket wheel.
The extent of movement required is obtained by placing the arm at the required
distance from the hinges, of the door k., represents an ordinary boxed
spring and arm, for closing the. door, but any other sort of spring or a weight
may be used.
Instead of transmitting the movement by pulleys, bell crank levers may be used.
When urinal stalls have simply to have liquid disinfectant supplied to them, by
a hinged platform, this may be effected by the arrangement illustrated by Fig. 1,
without using the water valve.
Or if disinfectant is to be supplied to a number of urinal stalls from one cistern
this may be effected by one cistern having as many separate bucket wheels, each
bucket wheel a separate ratchet wheel attached to the bucket wheel, and a
retaining pawl, and a separate trough for the disinfectant discharged by each
bucket wheel, and a separate pipe conveying the disinfectant to the urinal stall,
required.
Each ratchet wheel would by this arrangement have a separate arm and pawl
for actuating the ratchet wheel, the arm for each pawl being connected by a wire
chain or other suitable connection with the hinged platform which is to actuate it.
In some cases, there are several urinal stalls side by side, which are flushed by
one water pipe, discharging into one end of a channel into which the urine
drains.
Fig. 8 is a side elevation and Fig. 9 a front elevation of such urinal stalls,

page_text: h, the divisions forming the stalls; ', the channel for urine; h², the pipe at
one end for flushing with water."
Each of the stalls is or may be provided with a hinged platform f, such as that
hereinbefore described, connected by a wire or chain with a three armed lever b,-
on a fulcrum stud b, in the wall above each stall.
There is a stop a³, for the lowest position of the weighted arm 6', of the three
armed lever.
The end of the upper arm 6*, of each lever has a hole through it, through which
a wire or chain or other connection m, can pass freely, but on the wire or chain
on one side of each arm a collar m², is secured, that will not pass through the hole
in the upper lever.
One end of the chain or wire m, is connected with the ratchet pawl arm b', for
actuating the bucket wheel, which when moved discharges liquid disinfectant by
the pipe a, into the water flushing pipe A³.
In Fig. 9 all the hinged platforms f, are shown in their highest positions, and"
when any one of them is stepped upon (say the one on the extreme right) the
connection m, is pulled as it passes freely through the holes in the arms 6*, of all
the other levers 6, without moving them, and actuates the bucket wheel and thus-
gives a discharge of disinfectant.
Should the platform f, for the stall on the extreme left be depressed this also.
causes a discharge from the bucket wheel, the wire chain or connection m, extending
between it and the other levers becoming slack, so that a discharge of disinfectant
will be given whichever platform is depressed.
But should two or more platforms f, be depressed at the same time, there will
only be one discharge of disinfectant, and the discharge of disinfectant will only.
be made after the first when all the platforms have risen if several are down at
the same time.
The pawl arm b³, is weighted sufficiently to keep the chain wire or connection m,-
stretched when free.
In order to give a discharge of disinfectant whenever a platform f, is depressed
and other discharges without waiting for the rise of the platform after being
depressed, the arrangements illustrated by Figs. 10 and 11 is or may be used.
On the fulcrum stud 6, of each three armed lever b, another arm or lever n
is placed and is free to oscillate. The upper end of this arm n, has a hole in it
for the wire chain or connection m, and has a collar m³, secured to the connection.
on one side of this arm as explained in reference to the arms 6x, Fig. 9.
The upper end of the arm n, has a projection n¹, for one end of a pawl to catch:
проп.
This pawl n', is jointed un a stud n³, in the side of the end of the upper arm 6*,-
of the three armed lever b.
This pawl n³, has a weighted tail part n', to keep the upper catch end of the
pawl upwards, and there is a projection n³, from the side of this tail part that comes
against the side of the upright arm 6x, to keep the catch end of the pawl nº, from
lifting too high.
As shown in Fig. 10, the pawl n², has hold of the projection n', from the upper-
end of the arm n, and when the three armed lever b, is moved in the direction shown
by the arrow on Fig. 10 the arm n, is carried with it, and the connection m, and
the pawl lever b6, of the bucket wheel is also moved.
Just before the arm n, arrives at its extreme movement in the direction pointed
by the arrow on Fig. 10-a projection n', from the tail part n, of the pawl comes.
against the end of a set screw n', in a stud in the wall or support, and this causes.
the catch end of the pawl n³, to be released from the projection n', on the arm n
at about the end of its movement in the direction pointed by the arrow on Fig. 10
when the arm n, will be free to pass back to its first position against the stop a',
and when the platform f, rises again, the upper side of the catch end of the
awl n², will come under the projection n', on the arm n, and after passing it will

page_text: then fall into the position in which it is shown in Fig. 10 ready to operate upon the
arm n, again.
The bucket wheel by this arrangement will be operated to make a discharge
of disinfectant every time any one of the platforms, is depressed, if there is say
an interval for one action (say one second of time) between the depressions of the
hinged platforms.
In some cases there may be one wide bucket wheel, with its buckets divided in
the width-way into as many divisions as there are stalls to be served with disin-
fectant and there is a receiving trough for such bucket wheel also divided to
receive the disinfectant discharged from each division of the bucket wheel, one
division of the trough for each division of the bucket wheel.
Each division of the trough is connected by a separate pipe with the stall to be
served by it.
The bucket wheel has one ratchet wheel at either end of its axis as convenient,
and one ratchet pawl and arm for actuating it and a retaining pawl. Such
a bucket wheel can be operated by the movement of a door or by a moving
platform or platforms as hereinbefore described, if by moving platforms in
adjoining stalls, the arrangement explained by reference to Figs. 10 and 11 is or
may be used.
Whenever the bucket wheel. is actuated a discharge of disinfectant will be
delivered to each stall simultaneously, the cistern being in such position that the
disinfectant will flow by gravity to the stall.
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.
