Improvements in Apparatus for Mixing Liquids designed for
Disinfecting and other Purposes.
We, EUGENE JEAN BAPTISTE PAUL JODELAY, of 7 Cité Cardinal-Lemoine,
and MARIE JOSEPH EMILE LAURANS, of 37 Rue de la Tombe-Issoire, both of
Paris, in the Republic of France, Merchants, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to apparatus for mixing liquids designed for disinfecting
and other purposes.
By the improved apparatus we can distribute and mix antiseptic liquids or
solutions in any desired proportions with water under pressure whether it be
distributed in pipes or not. In order to automatically effect the mixing we utilize
the pressure of the water which is to be charged with an antiseptic and which we
cause for this purpose to pass into our apparatus. In principle the latter is
composed of a cylinder wherein a piston can move under the pressure of the water,
this piston displacing the antiseptic liquid and compelling it to pass to the part of
the cylinder into which the water flows and in which the mixing takes place. The
mixture produced is then conducted by means of a hose or pipe to any desired
place. Our improved apparatus is specially designed for watering and disinfecting
roads and public places, pavements and kennel-stones, the surroundings of trees, the
benches and seats of walks or resorts, public market-places, courts, assembly rooms,
drain pipes, sale rooms, carriages, fronts of houses and generally any surfaces or
places which may or may not be accessible to the means heretofore used, and where
household waste and organic materials in a state of putrefaction usually accumulate,
the disinfection of such places being often more necessary than that of the road,
which is at present almost exclusively effected.
Moreover, the sprinkling of disinfectants by our apparatus necessitates no
more labour than the ordinary watering and the quantity of antiseptic used is
reduced to a minimum by reason of its being intimately mixed with the water under
pressure and by the pressure of this water itself, which enables the uniform and
proper distribution of the same to take place.
Its employment is therefore much more practical and advantageous than the
ordinary means, which consist either in the spreading of any antiseptic solution
distributed by a reservoir or a receptacle drawn by hand or by a horse, which
mode permits only of the watering of the road, or else in the watering by hand,
which is imperfect and costly and can be used only with small and easily accessible
surfaces.
Our apparatus comprises a receptacle of cylindrical form which is closed at each
of its extremities by a lid secured to the same, and in which an ordinary pump
piston is adapted to move, this piston having leather packing pieces held in their
place by discs; these discs carry two rods provided each with a ring and guided in
bosses in the interior of the cylinder, which bosses limit the upward movement of
the said piston.
The upper lid is provided with two screw threaded tubulures and two screw
plugs, and the lower lid is cast with a boss which limits the downward movement
of the piston and prevents the latter bearing at the end of its movement upon one

page_text: of the leather packing pieces. At its lower part the cylinder is provided with a
tubulure upon which is fixed a cylindrical pipe closed by a screw plug and having
at its upper part a cock. This cock puts the said pipe in communication with the
upper part of the cylinder by means of a small tube slit at its free extremity,
which has a conical screw thread and is provided with a screw plug of conical
shape, the slit extremity and its plug being opposite one of the before-mentioned
tubulures on the upper tid.
A pipe which may also be closed at the top by a screw plug enables the cylinder
to be set in communication with the atmosphere. Plugs are suitably arranged
for facilitating the emptying of the apparatus.
For introducing the antiseptic liquid or solution into the apparatus we unscrew
the plugs from the upper ends of the two pipes and place the piston at the upper
end of its movement by pulling its rods by means of hooks passing through the
orifices of the plugs of the upper lid and engaging with the rings fastened to the
said rods. The air imprisoned between the piston and the upper lid can escape
through the second of the aforesaid pipes. We close the cock before referred to
and introduce through the first pipe the antiseptic liquid or solution to be mixed
with the water; we then screw the said plugs upon the two pipes, open the cock
and admit water into the cylinder through the tubulure in order to let it pass out
through the second tubulure. Under the action of the pressure of the water which,
arriving through the first tubulure, fills the space in the cylinder above the piston
before escaping through the second tubulure and in proportion to its load the piston
descends, forcing the antiseptic liquid through the first pipe, the cock and the
slits in the small tube. The water which flows through the first tubulure becomes
mixed with the antiseptic liquid and escapes with it through the adjutage or the
hose or pipe connected to the second tubulure. This hose or pipe may be held
in any direction and, as hereinbefore stated, we can disinfect any place
within reach of the jet, and as the apparatus is very portable it follows that
there is no point which cannot be reached by the mixture of water and antiseptic
liquid.
The slits in the small pipe may be more or less uncovered by the plug; it
will be seen that by suitably screwing or unscrewing this plug we may change
the proportions of the disinfecting mixture which can be optionally regulated
once for all.
The forcing of the antiseptic liquid imprisoned below the piston is effected
automatically with perfect regularity and always in proportion to the discharge of
water, because the quantity of the solution used takes place by the effect of the
pressure of the water itself and augments or diminishes with this pressure, and
because it can in no case become independent of the variations which the said
pressure of the water may undergo.
It should be observed that our mixing apparatus may be used not only for
disinfection, but also for sprinkling phyloxerated vines, for washing of trees, for
sprinkling trees for fertilizing purposes, for extinguishing fire and for other
similar uses, by replacing, according to circumstances, the antiseptic liquid by carbon
disulphide, liquid which destroys plaut lice, sulphuric acid and in general by any
other appropriate liquid.
Of course the two tubulures may be arranged as well upon the cylinder itself as
upon the upper lid, or one of them may be arranged upon the cylinder and the
upon the upper lid.

page_text: Improvements in Apparatus for Mixing Liquids designed for
Disinfecting and other Purposes.
We, EUGENE JEAN BAPTISTE PAUL JODELAY, of 7 Cité Cardinal-Lemoine,
and MARIE JOSEPH EMILE LAURANS, of 37 Rue de la Tombe-Issoire, both of
Paris, in the Republic of France, Merchants, 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 designed for the distribution and mixture in
any desired proportions of a liquid or any antiseptic solution with water under
pressure by using for the automatic operation with such mixture, the pressure of
the water itself, which is to be charged with antiseptic matter and which is for this
purpose caused to pass into the apparatus.
For this purpose our improved apparatus is composed in principle of a cylinder,
in which a piston is adapted to slide under the pressure of the water, which
piston forces the antiseptic liquid back and compels the same to pass into that
part of the cylinder where the water enters and where the mixing takes place.
This mixture is then directed toward any desired place by means of a pipe or
hose.
Our apparatus is especially designed for sprinkling and disinfecting roads and
public places, pavements and gutters, the watering of the roots of trees, benches
and seats of walks, market-places, yards, assembly-halls, theatres, drain-pipes, halls,
waggons, the fronts of houses and in general all surfaces or places which are
accessible or not with such apparatus as serve for similar purposes and as are
used at present.
Our apparatus is also applicable to many other purposes, of which we will
hereafter mention the more important :-viz.
The mixing of fertilizing liquids for green-houses, trees 'and plants.
The mixture of antiparasitic liquids such as nicotine for use in green-houses, on
seed beds, and for trees by sprinkling.
The mixture of liquids for shower baths, for inhalation, injection and the
like.
The mixture of liquids for washing, bleaching and cleaning the fronts of houses
and any other surfaces.
The mixture of liquids serving to disinfect sand covered basins or reservoirs,
rubbish, hospital rooms and the like.
The mixture of liquids serving for carbonating the juices in sugar-refineries, for
the fermentation in distilleries and for other operations of a similar kind, the success
of which is secured by the homogeneousness of the operation.
The mixture of fire-extinguishing liquids, so that our apparatus may constitute
an effective fire extinguisher.
The mixture of antiseptic and disinfecting liquid for mixing with the flushing
water of urinals.
Purification of water by adding a quantity of the solution of alum usually
employed which up to the present time has only been done approximately, whereas
by using our apparatus, the quantity to be added is always exactly controllable.
Moreover the disinfecting sprinkling operation with our apparatus does not
necessitate any more work than the ordinary water sprinkling operation, and the
cost of antiseptic material is reduced to a minimum owing to its intimate and
regular mixing with the water under pressure and by the pressure of the water
itself, which allows of a uniform and sufficient distribution.
The use of our apparatus is therefore much more practical and advantageous
than the ordinary means which consist either in the spreading of any antiseptic

page_text: "
solution, distributed by a reservoir or vessel, drawn by hand or horse power or
otherwise, which process only permits of sprinkling the roads; or also of the
sprinkling by hand, which is imperfect and costly and only applicable for limited
and easily accessible surfaces.
In the accompanying drawing
Figure 1 is a vertical section on the line 1-2 of Figure 2, of a certain
constructional form of our mixing apparatus.
Figure 2 is a plan of Figure 1;
Figures 3 and 4 are respectively, a vertical section and a plan of the nozzle and
its tubule, drawn to a larger scale.
Figure 5 represents a detail, half in elevation and half in section of the
pulverizing jet-nozzle.
. Figure 6 is a vertical section through the axis of a modified form of our
apparatus.
Figure 7 is a vertical section on the line 3. 4 Fig. 8 of another form of
construction, and
Fig. 7 is an enlarged detail view of part of Fig. 7.
Figure 8 is a plan of Fig. 7.
Our apparatus comprises a receptacle a of cylindrical form, closed at its
extremities by lids a¹ a² and in which an ordinary pump-piston 6 with leather-
packings 66, can move, these packings being held in position by means of
plates 66 fastened to one another.
The guiding of the piston b in the cylinder a may be effected in different
ways. For instance by means of a three armed piece c fixed by a stud or
screw to the centre of the piston and the arms of which, provided with
friction rollers c¹ roll along the inner wall of the cylinder a thus preventing
the piston from sticking fast or becoming wedged in the cylinder (Figures
and 2).
We may also, as indicated in Figure 6, make the piston 6 of a sufficient height
in proportion to its radius, that the elongated form of the piston itself prevents the
same from becoming wedged and secures a good guide.
Another means of effecting the same object consists as indicated in Figures 7,
and 8 in providing the piston 6 with vertical rods 6 6 guided in lugs a³ forming
part of the cylindrical jacket a. But this arrangement has the disadvantage of
not allowing so perfect a utilization of the inner capacity of the cylinder a as the
preceding ones, for receiving the products to be mixed with water under pressure,
as will be understood from the following.
Finally may simply provide the piston with a single central rod, suitably
guided in the lid a¹ of the cylinder a in which it works tightly. Whichever
of the above described arrangements illustrated in Figures 1, 2, 6 and 7, may be
adopted, it will be necessary to provide in the upper lid a' of the cylinder a
suitably arranged orifices in order that by means of a hook or other appropriate
means the piston can be caused to rise to its uppermost position, by acting either
beneath the arms of the piece c (Figures 1 and 2) or upon the rings 6° (Figures 6
and 7) with which the free extremities of the rods fixed to the piston are
provided or the piston itself. The orifices a (Figures 7 and 8) which correspond
to the rods 6 of the piston can be hermetically closed by means of plugs d d.
The upper lid a¹ is provided with two screw-threaded nozzles t, t¹ on which the
inlet and outlet tubes for the water under pressure are fixed.
Furthermore the cylinder a or its bottom a' is provided with a tube f, to which
a tube is fixed, which can be closed by a plug screwed upon the end f³.
The tube is provided toward its upper part with a cock g, which establishes
communication between the said tube and the top of the cylinder a by the
intermediation of a small tube 7, into which a nozzle h¹ provided with a central
hole (Figures 3 and 4) is screwed.
The nozzle, the shoulder of which has the same diameter or about the same
diameter as the tube h is located together with a part of the said tube in the exit

page_text: nozzle t¹ for the water under pressure, so that this water escapes around the said
tube h and the nozzle h¹ and produces owing to its speed the suction of the liquid
or of the antiseptic solution. The tube h may of course be arranged at any other
suitable place, either in front of the entrance nozzle of the water under pressure or
at any other point. But by placing the same in the exit opening t¹ we have the
advantage of obtaining a readier mixing of the antiseptic matter or the like with
the water and likewise a readier adjustment of the charge of antiseptic matter or
the like.
A tube which may also be closed at the top by a screw threaded_plug
permits of the communication of the cylinder a with the atmosphere. Blow off
cocks and k¹ are suitably placed in the bottom of the cylinder a.
The apparatus rests upon the ground by means of legs a³ (Figures 1 and 6) or
by means of the base plate a² itself.
As indicated in Figures 3 and 4 the outer form of the nozzle h¹ is of square
transverse section so that the cocks g k¹ and the nozzle h¹ can be manipulated by
means of one and the same key.
The operation of our apparatus is as follows:-
For introducing into the apparatus the liquid or antiseptic solution the plugs
at and are unscrewed and the piston b is brought into its upper position.
The cock 9 is closed and through the tube f¹ the liquid or antiseptic solution
to be mixed with water is introduced. The compressed air escapes through the
tube . Thereupon the plugs f' and are screwed onto the tubes f1 and i.
the cock g is opened and the water caused to arrive through the nozzle t so as
to allow it to flow through the nozzle t¹. Under the action of the uniform pressure
of the water which, arriving at t fills up that part of the inner space of the
cylinder a which lies above the piston b before its escape into t', in proportion of
its own weight, the piston 6 descends, forcing at the same time the antiseptic liquid
through the tube f¹, the cock g and the nozzle h¹.
The water which enters through the nozzle t takes in the antiseptic liquid and
escapes therewith through the adjutage or nozzle t¹ to which the tube m with itss.
nozzle has been attached. This nozzle can be passed in every direction and
anybody is thus enabled to disinfect, as above explained, any place lying within
reach of the jet, and as the apparatus is easily transportable, it follows that there
is no place to which access can not he had by this mixture of water and antiseptic
liquid. The nozzle which terminates the flexible pipe m is preferably of the type
shown in Figs. 1 and 5.
This nozzle arrangement as is illustrated in detail in Figures 3 and 4, allows
by the aid of a series of exchangeable nozzles of variable diameter, to regulate the
delivery and distribution of the antiseptic matter at will.
In the constructional form shown in Figure 7 the radial slots provided in the
pipe / may be more or less uncovered by the plug ; by respectively screwing or
unscrewing this plug the proportious of the disinfecting mixture may be varied
and regulated at will. The discharge of the antiseptic liquid enclosed beneath
the piston is effected automatically with perfect regularity and always with a
delivery proportional to the delivery of the water since this delivery of the
previously regulated solution takes place by the effect of the water pressure
it thus always increases or decreases in proportion of the said water-pressure.
The tube m terminating in a nozzle n, is of the special construction indicated in
Figure 5. Through this nozzle n the liquid is forced into one or a plurality of
helicoidal grooves n', cut out in the external wall of the extremity of the body n
covered with a cap n². This liquid becomes atomized owing to the rotary move-
ment which is imparted to it and leaves the orifice n³ in the form of a fine shower
or spray.
The nozzles t t may of course be arranged on the cylinder a instead of on the
upper lid a¹ or one of them may be arranged on the cylinder a and the other on
the upper lid a'; the cylinder a may be arranged horizontal, vertical or inclined.
The pipes or tubes ff¹ through which the antiseptic or other solution to be mixed

page_text: passes, can be otherwise arranged and in such a manner that at the end of
the operation the whole volume of the antiseptic matter or of the solution will
be used up.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. An apparatus producing a distribution and mixture in all desired propertions
of water under pressure set in communication by means of a pipe-system, with
antiseptic or non-antiseptic liquids or solutions, this distribution and this mixture
being obtained by the pressure itself of the water employed.
2. In an apparatus constructed in conformity with the first claim a cylinder a
intercalcated into the conduit of the liquid under pressure and divided by a
piston 6 into two compartments communicating with each other by a conduit (ff1
I h) capable of being cut off by which conduit the admission of the liquids or
of the solution to be mixed with the liquid under pressure is effected.
3. In an apparatus constructed in conformity with the first claim a guiding
device for the piston b comprising a piece c with three arms fixed to the centre of
the piston and the arms of which, provided with friction rollers rolling upon
the interior wall of the cylinder a, prevent angular displacement of the piston in
said cylinder.
4. In an apparatus constructed in conformity with the first claim a guiding
device for the piston consisting in giving this piston a sufficient height in
order that no angular displacement of the piston in the cylinder can take place.
5. In an apparatus constructed in conformity with the first claim a guiding
device for the piston b comprising two vertical rods with which this piston is
provided, these rods being guided in sockets forming part of the cylindrical
jacket.
6. In an apparatus constructed in conformity with the first claim, a guiding
device for the piston 6 comprising a central rod connected to the piston and guided
in the cover of the cylinder which it fits tightly.
7. In an apparatus constructed in conformity with the first claim an arrangement
for regulating the delivery from the conduit producing the communication between
the two compartments of the cylinder, and consisting of a small pipe
upon which
a tubular connection ' of square shaped cross-section is screwed in order to allow of
its being operated upon with a key from outside, and which is pierced with a central
hole, the diameter of which depends upon the delivery required to be obtained
when the said tubular connection is set in place.
8. In an apparatus devised in conformity with the first claim an arrangement for
regulating the delivery from the conduit producing the communication between the
two compartments of the cylinder, and consisting of a small tube h terminating in
a screw-threaded portion with radial slits, and upon which is screwed from outside
a stopper with square shaped head which permits of reducing the section of the
passage for the liquid to the desired degree, by covering up more or less the slits
of the tube h.
9. In an apparatus devised in conformity with the first claim an arrangement
for producing a communication between the cylinder and the atmospheric air,
comprising a pipe (i) which passes out into the cylinder a beneath the piston b
when this piston is in its raised position; this pipe being arranged so as to be
capable of being closed at its upper extremity by a screw stopper.
