Improvements in Spray Producers.
1, FRANCIS FAYOD, Engineer, of 39 Rami Strasse, Zurich, in Switzerland, do
hereby declare the nature of this invention to be as follows:-
Syringes which have been used of late for distributing water by means of conical
or annular distributer (atomizer or spray instrument), has a drawback, that the
opening for the water which naturally must consist of very small openings or of an
annular slit, very soon get stopped up by the impurities contained in the water, so
that the intended effect of the syringe is very questionable.
The present invention has for its object to hinder the stopping up of the opening
for the water in a self acting way as in consequence of the narrowing of the slits
the water pressure at the outlet causes the atomizer to move in such a way that an
enlargement of the slits occur so that the stronger flowing spray produces a
washing which removes impurities after which the atomizer returns to its old
normal position.
By syringes of this kind and in fact by all syringes the useful effect depends upon
a certain and constant water pressure in the syringes. In order to be able to
regulate and observe the pressure, a forcing valve and manometer are employed.
The water coming from the water supply is reduced to a certain pressure for
which the syringe is constructed by a valve of usual construction, the water going
into a water chamber of the syringe, and leaves through an opening at the bottom,
which is contracted by a conical regulator so that the water descends in the form of
a damp mist, the said conical regulator operates on a male screw running up the
centre of the apparatus and on which the movable parts inside the casing of the
syringe are regulated.
To the male screw a reed cylinder is attached enclosing a second cylinder, which
descends on a crosspiece in the water chamber. Inside the second cylinder, a
cylinder of india rubber is placed which encloses at the same time a portion of the
male screw. By this arrangement the regulator rests on the india rubber cylinder.
As soon as impurity in the water stop up the outlet for the water, the water begins
to flow irregularly and the working is hindered; but before it comes to this the
retension of the water at the outlet will increase the pressure which acts upon the
regulator, pressing the same downwards. A pull is hereby given to the male screw,
which causes the india rubber cylinder to be pressed downwards so that the conical
regulator can fall whereby the water outlet is enlarged, so that a larger water spray
is the consequence which removes the impurities that have collected in the
outlet.
When the cleansing has been effected the elasticity of the india rubber cylinder
causes the male screw to ascend whereby the regulator returns to its normal
position.
To the water chamber of the syringe a manometer is attached in order to be able
to observe the pressure of the water in the syringe.
The invention concerns also some peculiar constructions by which a very useful
effect is obtained even if there is little water and a moderate pressure say about
1 atmos., this result is obtained that the central water spray entering the syringe is
converted by degrees into a fine annular spray before it makes its exit through
the nozzle openings or an annular slit, and that the water at the outlet has a frictionless
slide owing to a reposing mass of water.
The water entering the syringe fills at first the central space and goes from there
through slits into the annular chamber. The parabolic body contracts the annular
spray and conducts it on to the disc which has a conical shape nearly reaching

page_text: the walls of the casing, in order to obtain a very fine annular water spray.
The
water running down on the outside of the disc and on the walls of the casing meets
the water in the water chamber and leaves the syringe through slits in a conical
spray.
By gradually turning the full water spray by means of a disc into a fine annular
spray and by the nearly fractionless deviation of the vertical water spray into a
horizontal or conical one, the syringe, in particular when used for ventilating
purposes, has such a useful effect as has not been reached by any other syringe now

Improvements in Spray Producers.
1, FRANCIS FAYOD, of 39 Rami Strasse, Zurich, in Switzerland, Engineer,
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:-
Syringes which have been used of late for distributing water by means of conical
or annular distributer (regulator or spray instrument) has a drawback, that the
opening for the water which naturally must consist of very small openings or of an
annular slit, very soon get stopped up by the impurities contained in the water, so
that the intended effect of the syringe is very questionable.
The present invention has for its object to hinder the stopping up of the opening
for the water in a self acting way as in consequence of the narrowing of the slits
the water pressure at the outlet causes the regulator to move in such a way that an
enlargement of the slits occur so that the stronger flowing spray produces a washing
which removes impurities after which the regulator returns to its old normal
position.
By syringes of this kind and in fact by all syringes the useful effect depends upon
a certain and constant water pressure in the syringe. In order to be able to
regulate and observe the pressure, a forcing valve and manometer are employed.
The water coming from the water supply is reduced to a certain pressure for
which the syringe is constructed by a valve of usual construction, and enters into a
water chamber of the syringe and leaves through an opening at the bottom which is
contracted by a conical regulator so that the water descends in the form of a damp
mist; the said conical regulator operates on a male screw running up the centre of
the apparatus on which the movable parts inside the casing of the syringe are
regulated.
To the male screw a reed cylinder is attached which encloses a second
cylinder, which descends on a crosspiece in the water chamber. Inside the
second cylinder, a cylinder of india rubber is placed which encloses at the same
time a portion of the male screw. By this arrangement the regulator rests on
the india rubber cylinder. As soon as impurity in the water stop up the
outlet for the water, the water begins to flow irregularly and the working is
hindered; but before it comes to this the retension of the water at the outlet
will increase the pressure which acts upon the regulator, pressing the same
downwards. A pull is hereby given to the male screw, which causes the india
rubber cylinder to be pressed downwards so that the conical regulator can fall
whereby the water outlet is enlarged, so that a larger water spray is the con-
sequence which removes the impurities that have collected in the outlet.
When the cleansing has been effected the elasticity of the india rubber cylinder
causes the male screw to ascend whereby the regulator returns to its normal
position.

page_text: To the water chamber of the syringe a manometer is attached in order to be able
to observe the pressure of the water in the syringe.
The invention concerns also some peculiar constructions by which a very useful
effect is obtained even if there is little water and a moderate pressure say about
1 atmos., this result is obtained that the central water spray entering the syringe is
converted by degrees into a fine annular spray before it makes its exit through the
nozzle openings or an annular slit, and that the water at the outlet has a frictionless
slide owing to a reposing mass of water.
The water entering the syringe fills at first the central space and goes from
there through slits into the annular chamber. The parabolic body contracts the
annular spray and conducts it on to the disc which has a conical shape nearly
reaching the walls of the casing, in order to obtain a very fine annular water spray.
The water running down on the outside of the disc and on the walls of the casing
mects the water in the water chamber and leaves the syringe through slits in a
conical spray.
By gradually turning the full water spray by means of a disc into a fine annular
spray and by the nearly fractionless deviation of the vertical water spray into a
horizontal or conical one, the syringe, in particular when used for ventilating
purposes, has such a useful effect as has not been reached by any other syringe now
in use.
In the accompanying drawing
Fig. 1 is a vertical section of the spray producer A; Fig. 2, is a horizontal
section from X1 X2; Fig. 3, from X3 X4; Fig. 4 is the top view of the
distributer Fig. 5, is a longitudinal and Fig. 6 is a horizontal section from X5 X6
showing a distributer of a different construction.
The water coming from the supply a' is reduced to the certain pressure (about
4 atmospheres) for which the spray producer is constructed by the valve a
of usual construction. From a the water goes through the pipe a² into the
upper part and froin here into the water chamber of the syringe; here it
goes down and leaves by the opening 2 which is contracted to the necessary
degree by a conical regulator d. By turning the wing on the rod s which
has a screw, the regulator d can be accurately adjusted so that the certain
pressure of about 4 atmospheres produces a damp mist as soon as the water
flowing over leaves. The rod s is continued in rod whose screw possesses
a female screw which in the guide g¹ (Fig. 3) in the casing is made to slide
vertically. sands are guided in the cross piece e and e'. To a cylinder c
is attached which so works over a cylinder 2 placed on cross piece e thate
and can slide against each other. In ², and encircling, is an india rubber
cylinder c. This cylinder by above arrangement of the separate parts holds the
regulator das fand erest upon c or relatively upon e.
When the spray
producer is adjusted and under the above named water pressure it will work in
an effectual manner. But as soon as in consequence of the impurities contained
in the water, the outlet g is stopped up, the water will flow irregularly and
the working is hindered. Before however it comes to this the retension of the
water at the outlet will cause an increase of pressure acting upon d which is
thereby pressed down. The consequent pull on causes a compression of the
india rubber cylinder c, so that s, and d are allowed to fall. By this
means the water outlet section is enlarged and a stronger water spray is the
consequence which removes the impurities collected in the opening and effects
a rinsing of the regulator d.
When the cleansing has been effected the elasticity of the india rubber cylinder c
causes the female screw to ascend whereby the regulator d, returns to its normal
position.
In order to accurately observe and regulate the syringe, which through the
constant pressure in pipe a' and chamber will work in the most effectual
manner, a pressure reducing valve a of usual construction is attached to the
supply and through the tube b connecting it with the chamber y, a mano-

page_text: meter also of usual construction, is attached. In Fig. 5, the outlet is
contracted by a cone placed on the spindles by which the out coming water
is led on to a second cone d, this cone is constructed with tangential grooves
(Fig. 6) which causes a breaking up. of the water sprays thereby producing
a better dispersion for air damping purposes. By means of the movable hand
wheel d', d and can be made higher or lower. Otherwise the arrangement is
the same as described above.
:
Fig. 7, shows a longitudinal section of spray producer B while Fig. 8, is a
horizontal section from X 7 to X 8, and Fig. 9 from X9 to X 10.
The water entering the spray producer by means of a tube which is screwed
into fills the centre space R, from here it is distributed through the slit into the
annular chamber R. The parabolic body P contracts the annular spray and leads
it on to the disc P', which with its sharpened circuit almost touches the walls of the
casing, in order to produce a very fine annular spray.
The water flowing down P and the walls of the casing meets the water in the.
water chamber R2 is led outwards and goes through the slit r, where it leaves the
syringe in a conical spray.
By gradually turning the full water spray by means of a disc Pinto a fine
annular spray and by the nearly frictionless deviation of the vertical water spray
into a horizontal or conical one, the syringe, in particular when used for ventilating
purposes, has such a great useful effect as has not been reached by any other syringe
now in use.
The disc P is so arranged that, resting on a box c', which again rests in a box c²,
it is vertically displaceable in order to be properly placed in its position to the
slit c.
The placing in position is done by means of female screw or socket m on the
spindle which holds the box and guide e while s in the casing is held by the fly
nut which screws on s¹. If the guide e consists of an elastic india rubber tube
the object is attained of effecting a self acting washing when the stopping up of the
water outlet occurs, as the increasing water pressure on causes a compression
of the india rubber tube e whereby P falls so that the spray of water becomes stronger
and removes the impurities whereupon P¹ is again raised through the elasticity
of the tube c.
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 :-
1. In spray producers the combination of the distributer with an india rubber
tube or guide which, by compression produces a movement of the distributer to
increase the outflow of water anatomatically by rinsing or washing, substantially as
herein described.
2. The combination of a spray producer with a manometer b to observe the water
pressure in the spray producer, substantially as herein described and according to
the accompanying drawings.
3. The combination of a spray producer with a pressure reducing valve a, in
order to balance the water pressure in the spray producer, substantially as herein
described.
4. The application of a disc " in a spray producer with a higher water
chamber Rand a lower water chamber R², substantially as herein described and
according to the accompanying drawings.
