Improvements in Apparatus for Supplying Disinfectant to
Water-closets, Urinals, and the like.
1, WILLIAM HANLON, of The Rectory, Innishannon, County Cork, Ireland,
Clerk in Holy Orders, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for supplying disinfectant to water-closets,
urinals and the like.
Ir a particular form of my improved apparatus I attach to the flush pipe by
means hereinafter described an elbowed block from which is detachably supported
the receptacle containing the disinfectant, which latter may be in the form of
soluble crystals. The block carries a plug cock by means of which the supply of
disinfectant, discharged from the receptacle by the flush water, can be conveniently
regulated or cut off. The horizontal arm of the block is provided internally with
a passage which, registering with a hole in the flush pipe, forms a means of
communication between the latter and the disinfectant receptacle. That portion
of the said passage nearest the flush pipe is of larger internal diameter than the
remainder of the said passage. Within the passage is secured a tube or pipe of a
size corresponding to the narrow part of the passage and free to revolve therein.
The said tube extends through the hole in the flush pipe and is there so bent and
turned that its mouth will be open to the water when the latter flows down the
flush pipe. The said small pipe does not fit the opening in the flush pipe, whereby
an annular space is left around the said small pipe. Extending to the bottom
of the receptacle from a transverse hole in plug of cock which hole registers with
the smaller end of the passage in arm is a vertical tube or pipe around which an
In the
annular space is provided in the lower part of the plug of the cock.
plug of the cock is an opening communicating with the said annular space and a
corresponding port is provided in the wall of the cock socket. This port leads by
a small inclined passage into the interior of the horizontal arm. The annular
space around the vertical pipe is thus put into communication with the annular
chamber around the horizontal pipe in the elbow arm of the block.
As the flush water passes down the flush pipe part of it enters the central
horizontal tube and passes through the plug of the cock into the disinfectant
receptacle by descending the aforesaid vertical tube thereby displacing some of the
disinfectant fluid in the receptacle. The displaced fluid passes up into the annular
space inside the lower part of the plug and then flows through the small inclined
passage to the annular chamber, which surrounds the small horizontal pipe
protruding into the flush pipe, whence the fluid is discharged into the flush
pipe.
I may provide a perforated or other pipe surrounding the said small horizontal
pipe, a space being left between the two pipes through which space the water and
disinfectant issuing from the disinfectant receptacle flows. I may also provide a
small pipe, on the cock socket through which when the plug of the cock is turned
into the proper position the disinfecting liquid can be drawn off into any external
vessel, when the flush takes place, instead of its passing into the flush water. By
adjusting the cock the quantity of disinfectant discharged into the flusb pipe or
external vessel can be regulated or stopped as desired.

page_text: In another form of my apparatus the disinfectant receptacle is situated above
instead of below the elbowed block as in the previous construction. In this form
the plug of the cock and the bottom of the receptacle are made in one piece so
that by revolving the receptacle the supply of disinfectant can be regulated. The
receptacle may be retained in position by means of a nut or it may be screwed on
to the lower end of the plug of the cock. The receptacle is provided with three
internal concentric tubes or pipes one of which communicates with the central
inlet tube in the plug; another with the annular space in the plug surrounding the
inner tube; and another which surrounds the other tube tubes. The outer or last
mentioned tube is open at the top and is provided with a series of perforations
near the bottom. The innermost tube is louger than the other tubes and the
intermediate or second tube is shorter than either of the other tubes. The inner-
most tube is provided with perforations near the top thereof but. is closed at the
upper end and carries a plate or disc which covers the concentric tubes and
prevents the latter becoming choked with solid disinfectant when the same is
introduced through the top of the receptacle, which top is made removable for this
purpose.
I may also provide a small pipe on cock socket for the supply of disinfectant to
an external vessel, in the manner hereinbefore described.
fluid.
In a further modification the disinfectant receptacle communicates with the flush
pipe by openings at two points; one opening serving as the inlet for a portion of
the flush water and the other opening serving as the outlet for the disinfecting
With this apparatus there is no elbowed block as in the other forms herein-
before described. The receptacle is provided with an internal tube or pipe having
its upper opening near the top of the said receptacle, its lower opening being in
the flush pipe. The mouth of the lower opening is arranged to lie opposite the
direction of the flushing water so that the said water is guided thereby into the
receptacle. The upper end of said pipe is preferably curved downwardly and is
provided with a regulating cock or tap. Another tube advantageously perforated at
the lower end extends to or near to the bottom of the receptacle and the outlet pipe
to the flush pipe is connected to the said tube near the top thereof. The receptacle
is provided with an opening furnished with a cover at the top through which
opening the disinfectant is introduced into the receptacle. A portion of the flush
water enters by the lower tube which projects into the flush pipe whence it is
forced by the pressure of the water up the tube and into the receptacle. This
causes a corresponding amount of the disinfectant to flow up the other tube and
out by the outlet tube to the flush pipe.
In another modification of my invention I provide a very simple form of
apparatus which operates by syphonage instead of by displacenient or by gravity.
In this apparatus I provide an arm attached as hereinafter described to the flush
pipe carrying a plug cock furnished with claws by means of which an ordinary
medicine bottle having a suitable lip is adapted to be held. The said claws may
be made adjustable to enable bottles of different sizes to be used. The plug ís
provided with a downwardly extending syphou tube or pipe. By removing the
said plug and tube the bottle, containing in this case liquid disinfectant, can be
removed or replaced in the apparatus. The flow of the flush water in the flush
pipe causes a partial vacuum to be set up in the syphon and thus a certain amount
of the liquid disinfectant contained in the bottle will be withdrawn and intermingled
with the flush water.
For securing the apparatus to the flush pipe I screw thread the horizontal arm
which carries the plug cock and provide thereon a nut having arms which are
adapted to engage with openings in a flexible band which embraces the flush pipe.
By turning the said screw-threaded arm the uut will recede from or approach the
flush pipe so tightening or loosening the flexible band thus allowing of the easy
securing to or release of the apparatus from the flush pipe.
The other forms of apparatus 1 likewise secure to the flush pipe in an analogous
manner.

page_text: For ease in fixing my improved devices to the flush pipe I preferably provide
with each apparatus a combined boring bit and screw-driver; the former for use
in making the necessary hole or holes in the flush pipe and the latter for screwing
a screw or stud into the hole in the flush pipe to close the same if the apparatus
is removed.
I may combine two or more of these apparatus in one. In a modification of
this apparatus I protrude, as hereinbefore described, into the flush pipe a small
bent tube with its mouth presented to flow of water at a certain angle. While the
How of the flush water continues, some of it descends into bottle; when the flow
of water has ceased, the vacuum left behind it in the flush pipe sucks up some of
the disinfectant into the flush pipe.
Where it is desired to use two or more disinfectants of different natures, to mix
together for the first time in the flush water, I combine any two or more of my
apparatus.

Improvements in Apparatus for Supplying Disinfectant to
Water-closets, Urinals, and the like.
I, WILLIAM HANLON, of The Rectory, Innishannon, County Cork, Ireland,
Clerk in Holy Orders, 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 supplying disinfectants to water-closets,
urinals and the like, the said apparatus being constructed in two forms, the first in
which part of the water passing through the flush pipe is mingled with the
disinfectant, preferably in soluble crystals or other concentrated form, thereby
dissolving part of it, the resulting liquid being returned to the flush pipe to mix
with the flush water, or led to other places or receptacles as desired; and the second
form in which liquid disinfectants are used, a portion being induced from the
apparatus into the Bush pipe each time the flush water passes down the flush pipe.
Both forms are so constructed that the amount of disinfectant so dissolved or
commingled may be regulated or cut off at will.
In the accompanying drawings which illustrate my invention;
Figure 1 represents in vertical section an apparatus for use with concentrated
disinfectants, and
Figure 2 a horizontal section of the same on the line 1. 1 Figure 1.
Figure 3 represents in vertical section an alternative method of attaching the
apparatus shown in Figure 1 to the flush pipe; and
Figure 4 represents a vertical section of a similar apparatus of simpler form;

shown in Figure 5.
Figure 64 represents in vertical section a simpler form of the apparatus shown in
Figures 5 and 6.

page_text: Figure 6 shows a vertical section of a modification of the apparatus represented
by Figures 5 and 6 in which the container is screwed to the apparatus.
Figure 7 shows a vertical section of a modification of the apparatus shown in
Figures 5 and 6 adapted for use with concentrated disinfectants, and
Figure 8 a horizontal section of the same on the line 2. 2. Figure 7; and
Figure 9 illustrates a combined boring tool and screw driver especially adapted
for use in fitting the before mentioned apparatus in place.
Referring to Figure 1 which illustrates an apparatus for use with disinfectants
in a crystallized or other concentrated form, A is a receptacle or container for
holding the soluble disinfectant, provided at its upper end with a lid or cover B,
and having at its lower end a cock plug C revoluble in a conical hole formed in an
elbowed block or cock body D, the stem of which is alapte to be secured to the
flush pipe E in a manner hereinafter described.
The cock plug C which supports the container A is formed with two passages
and G, the lower F communicating with the upper part of the container A by
means of a pipe H and the upper passage G communicating by means of a second
tube I concentric with the tube H, with the upper end of a third concentric tube J,
the tube H extending through the tube J and its cover into the upper end of the
chamber A.
The elbowed block or cock body D is provided with three ports or passages
which correspond to the passages in the cock plug, the passage K communicating
with the passage F and the passage L communicating with the passage G, the
third passage M also communicates with the passage G when the container A an
with it the cock plug C are turned half way round. For indicating its position the
cuck is provided at its lower end with a pointer G. A pipe P opens into the port
or passage K in the elbowed block or sten D, the opposite extremity of which pipe
extends into the flush pipe where it is open and bent upward so as to admit part of
the flush water. The port or passage L also communicates with the flush pipe by
means of the annular chamber Q.
The container A having been supplied with soluble disinfectant and with
water to the level of the top of the intermediate pipe I the operation is as
follows:-
When the flush water is admitted to the flush pipe E a part of it is forced
through the pipe P, passage F and tube H into the upper part of the container A
falling into the disinfectant solution and causing the liquid level to rise in the
container above the upper end of the intermediate tube I. The water holding
most disinfectant in solution, that is to say, water from below the lower end of the
outer concentric tube J then Hows down the intermediate pipe I through the
passage L and annular chamber Q into the flush pipe E again, where it mixes with
the flush water. If it is desired to collect the disinfectant solution or to pass
it away, without allowing it to enter the Blush pipe, the cock plug is turned half
way round so that the passage G communicates with the passage M, as shown by
the index O, then the operation is the same as before except that the solution
leaves the apparatus by way of the pipe or passage M iustead of by the annular
passage Q. The amount of liquid passing in or out of the apparatus can be
regulated at will or entirely cut off by turning the cock plug partly round.
The container A is replenished with disinfectant by simply raising the cover
and dropping in the crystals or the like, the displaced liquid flowing into the flush
pipe.
For the purpose of attaching the apparatus to the flush pipe the stem of the
elbowed block or cock body D is screw threaded on its exterior and provided with
a nut R having a gudgeon or trunnion at each of two of its opposite sides.
A seat S is also provided for the stem D, having a flange curved to correspond
with the exterior form of the flush pipe.
When the apparatus is to be affixed to the flush pipe a hole is first bored in the
said pipe with a tool hereinafter described, which I prefer to supply with each
apparatus, the flanged seat is then placed in position on the flush pipe with

page_text: packing washer interposed between the flange and pipe, its tubular projection
being inserted in the hole. The stem of the block or cock body D having the
ut R screwed on is next placed on its seat S, a packing washer being interposed
between the stem and seat, then a flexible band T, provided with holes near its
extremities, is passed round the back of the flush pipe and its ends attached to the
gudgeons or trunnions of the nut R by inserting them into the holes in the band,
the cock body is then rotated in the nut R so as to cause the latter to recede from
the flush pipe and so to force the stem and seat flange upon their respective
packing washers as to make a thoroughly tight and substantial joint.
An alternative method of attaching this apparatus to the flush pipe is shown
in Figure 3. In this case the stem of the cock body D is provided at its extremity
with a flange adapted to be secured by screws or the like to a face or seat formed
on a portion of the flush pipe E, a packing washer being interposed between the
flange and the face or seat.
A modification of the first form of apparatus is illustrated in Figure 4, the
construction being somewhat simpler than in the foregoing case.
The container A
is attached to the flush pipe by means of two pipes, the upper P extending into the
flush pipe E, to which it is preferably soldered, and having that extremity open and
bent upward; the opposite part of the said pipe P terminates in the upper part of
the container where it is provided with a stop cock C, the plug of which may be
turned by means of a suitable key through a hole in the cover B, or after the said
cover is removed. The lower pipe Q terminates at one end just inside the flush
pipe and at the other end in the pipe I which latter together with the pipe J is
similar relatively to the container A to the corresponding parts of the apparatus
hereinbefore described.
Part of the water passing down the flush pipe E enters the container by way of
the pipe P-the amount being previously determined by means of the cock C,-
and displaces some of the dissolved disinfectant which rising in the pipe J, flows
over the top of, and down through the pipe I into the flush pipe by way of the
pipe Q. If desired the solution or a part thereof may be led off through an
extension of the pipe I provided with a stop-cock C, indicated by dotted lines
in Figure 4. The constituent parts of the apparatus may be fastened together and
the pipes P and Q attached to the flush pipe by soldering or by any other suitable
method,
An apparatus suitable for supplying liquid disinfectant to the flush pipe, is shown
in vertical section in Figures 5 and 6, and consists of a cock body D, whose stem
is attached to the flush pipe by either of the herein before described methods, and
a plug C which may be screw-threaded on its exterior and which is provided with
a lateral passage G communicating at one of its extremities with the flush pipe E
by way of the passage K in the cock body stem and at the centre with a pipe I
which may be made telescopic as shown and which exterds downwardly from the
plug C into a bottle or other container A for holding the disinfecting liquid.
The body of the cock carries arms or levers a the lower hooked ends of which are
adapted to grasp the neck of the bottle A just below the mouth. These arms or
levers a are carried on pins mounted in wings on the side of the cock body and are
provided at their upper ends with cams adapted to be actuated by a rotating collar
or disc b attached to the screwed cock plug or to another appropriate screw
provided with a suitable handle or other means by which it may be rotated; for
instance the actuating collar may be screw threaded internally so as to move up
and down when rotated on the externally screw threaded cock plug.
The plug C, as shewn in Figure 54 may have a screw threaded passage
throughout its length fitted with a screw N. Around the middle of the plug
is an annular groove G G opening into the said passage so that communication
may be always open between the pipe I and the passage K. The flow of liquid is
regulated or cut off by the descent of the screw N.
Instead of being retained in place by arms or levers as shewn in Figure 6, the
lip of the bottle A may rest on ledges a a formed on the support or cock body Das

page_text: shown in Figure 64. One side of the support is left open and when the bottle
mouth is placed therein the tube I may be inserted into it through the screw
threaded hole in the part D and the screw C turned therein until the passage K
coincides with the passage in the tube I. In this position the inner end of the
screw enters the mouth of the bottle and so prevents its renoval from the support
or cock body C.
In another modification the wings and levers are replaced by an externally
screw-threaded nipple R shown in Figure 6 on which a container A having a
screw-threaded opening to correspond is screwed. In this case a solid screw Cis
substituted for the plug employed in the former examples and this screw by its
descent regulates or cuts off the flow of liquid.
The container A is not necessarily attached to the body D, it may he inde-
pendently supported in any suitable manner, as for instance by attaching it to a
wall or placing it on a shelf.
The plug of the cock may be of the ordinary kind that is to say; it may have a
conical smooth working surface instead of being screw-threaded.
The bottle or container A having been supplied with the liquid disinfectant is
placed so that ita neck is grasped just below the mouth by the hooks at the lower
ends of the levers a for instance, the telescopic tubes being inserted into the mouth
of the bottle. The plug C on the annular collar is then screwed down until the
cams are forced apart sufficiently to cause he hooks to safely hold the bottle in
place. If the plug C is left in such a position that the passage for liquid from the
bottle to the flush pipe is open, a partial vacuum takes place in the passages G
and K and in the pipe I, when the flush water descends, and some of the liquid
from the bottle is forced through into the flush pipe E where it mixes with the
falling water. By turning the plug C the supply of disinfectant may be regulated
or entirely cut off as desired.
The latter form of apparatus slightly modified may also be used for crystallized
or other concentrated soluble disinfectant. Figures 7 and 8 illustrate an apparatus
adapted for this purpose, an alternate method of securing the container A in place
being also shown. In this case the cock plug C is arranged horizontally and is
preferably screw threaded and formed with a central passage G having a pipe K
extending therefrom into the flush pipe E the said pipe being provided in the flush
pipe with a mouth opening upwardly, the transverse part of the passage G
communicates with the tube I which extends into the disinfectant.
When the flush water descends a part of it is caught by the mouth of the pipe K
and conducted to the bottle A containing the disinfectant, which it partly dissolves.
After the flush water bas all passed the pipe K, a partial vacuum is created in the
flush pipe and consequently in the passages K G and I of the apparatus, and the
dissolved disinfectant is immediately forced up into the flush pipe.
For securing the bottle or container A in place, the cock body stem D is provided
on both sides with ledges or claws a, a one or each of which may be detachable and
secured to the cock body D when the container or bottle A is in place by means of
a screw c.
For fastening the two last described modifications to the flush pipe I prefer to
employ the method described with reference to Figures 1 and 2 of the drawings,
but I may use that described with reference to Figure 3, or any other suitable
method.
For the purpose of enabling my apparatus to be readily mounted on the flush
pipe, I preferably provide each apparatus with a combined boring bit and screw-
driver, shown in Figure 9 formed of one piece of metal, the boring bit d being at
one end and the screw driver e at the other. The boring bit d consists of a drill
and reamer point for making the hole in the pipe and lips or cutters, a short
distance from the point, for removing the burr formed by the drill in making the
bole. The end opposite the boring bit is book shaped for the purpose of providing
a handle wherewith to turn the bit or screw-driver e, the latter being formed at the

page_text: extremity of an outward turn of the rod or wire forming the tool and pointing in a
direction approximately at a right angle to the direction of the boring bit.
In operation the curved part of the tool is grasped by the hand and the boring
end rotated under pressure against the flush pipe where the hole is required until'
the burr is removed by the cutting shoulders ff. When the apparatus is removed:
for inspection or repair the hole in the flush pipe is plugged by means of a suitable.
screw inserted by the aid of the screw driver end of the boring tool.
