Improvements in or connected with Apparatus or Means for
Supplying Disinfectants, Perfumes, or other Matters to Water or
other Liquids.
I, ROBERT LEES, of 48, Mill Lane, Old Swan, in the County of Lancaster,
Iron Moulder, do hereby declare the nature of this invention to be as follows:
The present invention has reference to apparatus or means for feeding or
supplying disinfectants or purifying substances, or perfumes, to water in cisterns,
or water or other liquid containing vessels, tanks, sewers, drains, and the like..
According to this invention, the disinfectant, or purifying or other material, in
the form of crystals, or other suitable form, is enclosed or contained within a
vessel, which is placed within the liquid-containing vessel, tank, conduit, or the like,
the liquid in which is to be disinfected, purified; or be used as a disinfecting or
purifying fluid.
The mode according to this invention of delivering or supplying a disinfectant
to water or other liquid, consists in employing the variation of head of liquid in a
cistern, tank, conduit, or the like, for this purpose; as for instance, in the appli-
cation of the invention to supplying a disinfectant or the like to water in cisterns
wherein the water is supplied to said cistern and then drawn off, the fall of the
level from one point to another in the discharging of the cistern causes a certain
quantity of disinfectant or other matter, as the case may be, to be discharged into
the water.
and
One form of disinfectant or other matter containing vessel, bottle, or the like,
consists in providing therewith a tube or conduit extending from the lower part to
near the top, the top end being open to the water. At the upper end or top of the
vessel, bottle, or the like, is or are provided one or more apertures, holes, or
openings, which admit air- -water, and which may be adapted to be covered by
the water when the cistern fills. On filling the cistern, water can flow into the
vessel, bottle, or the like and as it empties the water which has entered said vessel,
causes a discharge of liquid and disinfectant, or other matter, to take place at the
discharge orifice of the tube or conduit above mentioned.
or
The lower end or part of the discharge tube or conduit may be in the form of a
strainer, such as perforated metal or gauze.
In some cases the vessel, bottle, or the like for containing disinfectants or purifying
substances or matters, or perfumes, is, in some cases, made of metal and of suitable
form, whilst in others it may be made of stoneware, earthenware, glass, or other
suitable substance.
The invention, the nature of which is above described, may be carried out in
different ways, and the parts constructed in different forms according to the different
purposes to which it may be applied, and requirements.

Improvements in or connected with Apparatus or Means for
Supplying Disinfectants, Perfumes, or other Matters to Water or
other Liquids.
I, ROBERT LEES, of 48, Mill Lane, Old Swan, in the County of Lancaster,
Iron Moulder, 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:-
The present invention has reference to apparatus or means for feeding or
supplying disinfectants or purifying substances or perfumes to water, in cisterns,
or water or other liquid containing vessels, tanks, sewers, drains, and the like, but
more particularly disinfectants.
According to this invention, the disinfectant or purifying or other material, in
the form of crystals, or other suitable form, is enclosed or contained within a vessel,
which is placed within the liquid-containing vessel, tank, conduit, or the like, the
liquid in which is to be disinfected, purified, or be used as a disinfecting or
purifying fluid.
The mode according to this invention of delivering or supplying a disinfectant
to water or other liquid consists in employing the variation of head of liquid in a
cistern, tank, conduit, or the like, for this purpose; as for instance, in the appli-
cation of the invention to supplying a disinfectant or the like to water in cisterns,
wherein the water is supplied to said cistern and then drawn off, the fall of the
level from one point to another in the discharging of the cistern causes a certain
quantity of disinfectant or other matter, as the case may be, to be discharged into
the water.
and
One form of disinfectant or other substance containing vessel, bottle, or the like,
consists in providing therewith a tube or conduit extending from the lower part to
near the top, the top end being open to the water. At the upper end or top of
the vessel, bottle, or the like, is or are provided one or more apertures, holes, or
openings, which admit water air, and which may be adapted to be covered by
the water when the cistern fills. On filling the cistern, water can flow into the
vessel, bottle, or the like, and as it empties the water which has entered said vessel,
causes a discharge of liquid and disinfectant, or other matter, to take place at the
discharge orifice of the tube or conduit above mentioned.
Or
The lower end or part of the discharge or conduit may be in the form of a
strainer, such as perforated metal or gauze.
In some cases the vessel, bottle, or the like for containing disinfectants or purifying
substances or matters, or perfumes, is, in some cases made of metal and of suitable
form, whilst in others it may be made of stoneware, earthenware, glass, or other
suitable substance.
In the drawings which serve to illustrate my invention, I shew several forms or
modifications thereof, all of which are shewn in sectional elevation.
The containing vessel shewn in the different figures may be taken to be of tin
or terne plate, seamed or soldered together in any suitable known way, and prefer-
ably of light material, and of round, rectilinear, or other convenient form in cross
section.
The containing vessel in these cases is designated a, whilst the outlet by which
the disinfectant or other liquid is discharged from the apparatus is designated b
and c is a strainer of wire gauze by which the entrance of crystals or material
forming the disinfectant to the discharged part b is prevented.
The entrance of water into the vessel a takes place through small apertures in
the top of the apparatus, namely, in the plate d, and this plate is, in all cases,
slightly above the discharge portion or orifice of the discharge pipe or part b, and

page_text: the difference between the level of the upper part, of the discharge part or pipe,
and the part by which the water enters the vessel a, is the measure of the head
under which the working of the apparatus takes place, and of the volume of liquid
passed through the apparatus in each operation.
The material used in most cases will be in the form of crystals, as for instance
permanganate of potash or equivalent crystals in the case of the employment of
disinfectants.
In Figure 1, the part of the pipe b inside a is vertical, and its lower end is
provided with a vertical metal gauze tube c.
In Figure 2 the gauze tube c lies in the horizontal plane at the bottom of the
vessel a, instead of vertically as in Figure 1.
In Figure 3, the gauze tube c is arranged similarly to that in Figure 2, but the
tube is taken outside the vessel a at the lower part of same.
In Figure 4 the top of the containing case or vessel a is flat, and is provided
with apertures therein; whilst it will be seen in Figure 1, 2, and 3, the top of the
case a is provided with a short tube d', by which means a comparatively large head
or difference of head is obtained, with only a small discharge volume in each action.
Otherwise than in these respects the apparatus shewn in Figure 4 is the same as
that in Figure 3.
The modification shewn in Figure 5 consists in providing an inner chamber a¹
within a, to receive and hold the disinfecting material (say permanganate of potash
or other suitable or required material), its lower part being provided with metallic
gauze c to prevent the material getting into the tube and stopping same.
course is equivalent to the tube c above specified fixed upon the tube b.
This of
The apparatus shewn in Figure 6 is a modification of that shewn in Figure 5,
but the disinfectant or other material is contained in the can outside the metallic
gauze vessel c lying horizontally across the vessel a, and this gauze also covers the
inlet end of the pipe d. The apparatus when or where desired may be filled with
the disinfectant or other material through an aperture in the top, side, or other
part, in or over which a screw or other plug, cap, or stopper is adapted to fit.
In Figure
the disinfectant or other material is adapted to be contained in the
left hand portion of the vessel a, and it is held there by a metallic vertical septum
or diaphragm a' at the top, and a gauze diaphragm c at the bottom, the latter
serving as a strainer to prevent the material in a from entering and stopping
the discharge tube b, which in this case is disposed in the right hand side portion
of the vessel.
In Figure 8 the apparatus is exactly similar to that shewn in Figure 7 with the
exception that it is of double form, the disinfectant or other material being contained
in the outer parts of a separated off by the diaphragms a¹c.
Figure 9 shews an apparatus according to this invention in which the disinfectant
or other material is contained within a metallic gauze wrapper or case c, which may
be suspended as shewn, or loose, the outlet being arranged at the top at 6 or in
any of the manners herein described, the entry of water to a being effected by the
pipe d'
In Figure 10 the vessel a has a central tube a running through it, outside which
is an annular pendant tube a¹, the annular space between a¹ and a² serving to
convey the water down into the vessel, apertures being provided in the upper
plated for such entrance of water; the plate & serving as the outlet.
To use the apparatus, it is placed in a cistern or tank with its base resting upon
the bottom thereof, or in other suitable position. As the tank is discharged, the
level of liquid therein falls below the upper part of the vessel a, in which the liquid
inlet apertures are provided. The uppermost part being full of water, and for the
time being above the level of the liquid in the tank, a discharge from a takes place
by way of the discharge pipe aperture or part b, through the latter being lower
than d or d¹. On the refilling of the cistern or tank, the vessel a is again filled
with a fresh quantity of water; and thus for each emptying or operation of the
cistern or tank a fresh quantity of material in a is dissolved and is forced through

page_text: the apparatus and discharged into the water in the cistern or tank. According to
the quantity of liquid introduced in each operation, and the quantity of disinfectant
in the liquid containing vessel, so will be the number of times a given size of
apparatus can be used.
The apparatus according to my invention if made of thin tin or like plate, and
in the form of a simple box or case, with a simple discharge pipe, can be very
cheaply and rapidly made; and it occupies very small space, which renders it
possible and easy of being introduced into all sizes of cisterns or tanks. Further-
more, by the use of the wire gauze either on the inlet of the discharge pipes of
disinfectant supply apparatus used in cisterns or tanks or as a container of the
material used therein, or a strainer, or in any way between the material on the
one hand and the inlet of the discharge pipe or conduit on the other, the discharge
pipe is prevented from becoming choked, and the operativeness of the apparatus,
until all the disinfectant is consumed or used, is assured.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim in respect thereof is :-
1. Apparatus for supplying disinfectants or other matters as specified to water
or other liquids, comprising a simple vessel (such as a) having an inlet at the top
and a discharge conduit or orifice slightly below the level of said inlet, whereby
a discharge of disinfectant is effected every time the cistern or tank in which the
apparatus is placed is used, the discharge being effected by the difference of head
of liquid in said vessel; substantially as herein set forth and shewn in the drawings
hereto annexed.
2. The different apparatus set forth respectively with reference to the different
figures of the drawings, having their parts constructed, arranged, and operating
particularly as specified and shown.
