Improvements in and relating to Apparatus for Projecting Liquids
under Pressure.
İ, HERMANN SPARLINGER, of Place Longemalle No. 1, Geneva, in the
Republic of Switzerland, Landlord of the Hotel du Lac, do hereby declare the
nature of this invention to be as follows:-
This invention relates to apparatus for the projection of liquids under pressure
and may be used for numerous purposes such for example as the extinguishing of
fires by means of a jet of water, or of a jet of water mixed with substances
intended to increase the extinguishing action of the same; the treatment of
vineyards for the destruction of the mildew by means of the projection of a
suitable liquid and for similar purposes.
In the accompanying drawing
Figure 1 is a vertical section showing by way of example, one form of apparatus
constructed according to my invention.
Figure 2 represents to an enlarged scale a section of the piston of the apparatus
shown in Figure 1 during its ascending stroke.
Figure 3 is a similar section showing the piston during its downward stroke
and
Figure 4 is a section of a combined jet and rose.
A is a tank divided by means of a wall or partition B into two superposed
compartments A' and A. The compartment Ais provided with an opening a
closed by means of a cover C and adapted to enable the liquid to be projected to
be introduced into the said compartment A. The second compartment A³ is
intended to receive the compressed air for acting upon the liquid contained in the
compartment A¹.
An air-pump composed of a cylinder D, a piston E and a valve F is secured to
the tank A in any suitable way and at any suitable point of the same, it may for
instance be located inside the said tank.
The interior portion of the cylinder D of said pump is connected with the
compartiment A of the tank by means of a pipe fin which is arranged a non-
return-valve F. The cover d¹ of the pump cylinder D is provided with holes
intended to establish communication between the upper part of the piston and the
open air.
The piston E is composed of a caoutchouc-ring e fitted into the cylinder D and
arranged somewhat loosely between two flanges e and secured to the shaft d.
The flange e is of such a shape, that when the ring e is resting upon the flange e³
(Figure 2) a circular channel is provided between said flange e and the inner
circumference of the ring e. As the flauge e is provided with a series of holes e³
arranged so as not to be covered over by the ringe the upper and under parts of
the piston are thus brought into direct communication with one another in this
particular position of the different parts; the latter will take said position during
the ascending stroke of the piston, in which the flange carries the ring e
upward.
I wish it understood that I call this stroke "the ascending stroke" with reference
to the arrangement of the pump as shown in the drawing, and that the same piston
may of course be arranged horizontally or otherwise

page_text: During the downward stroke of the piston (Figure 3) the flange e¹ moves the
ring e downward and the said flange el having no apertures the piston will then
close the cylinder D hermetically.
It follows from this arrangement that the piston just described works as suction
and force piston, the non-return valve E, mentioned above, being only intended to
prevent the pressure which is accumulated in the compartment A² from reacting
upon the underside of the piston during the upward stroke.
°
G is a tap intended both for letting out the liquid and for conveying the com-
pressed air from the compartment A³ to the compartment A'. The holes in the
plng of the said tap are so arranged that when the liquid contained in A¹ is
prevented from coming out, the compressed air in A is also prevented from passing
through the pipes g and g' into the compartment A' and vice versa.
This arrange
ment has a double object: 1st, to produce a bubbling up of the liquid contained
in the compartment A! at the precise moment when it is to be thrown out, this
being of great importance when the said liquid is a mixture which must be thrown
out only after having been made homogeneous by stirring it up; and 2nd, to.
produce the projection of said liquid through the tap G the pipe H and the
jet or rose attachment by means of the compressed air contained in the
compartment A³.
The apparatus can be put under pressure, and the cock G closed, so as to be
ready for immediate action when required, the capacity of the compartment A³
being large enough to contain, if desired, sufficient compressed air to project the
whole of the liquid contained in the compartment A'. The air may be pumped
into the compartment A' while the cock G is open, if it is desired to maintain a
constant pressure upon the liquid.
The nozzle or attachment I is arranged so as to be adapted to produce either a
straight jet of the liquid or a series of jets as from a rose. For this purpose the
said attachment is made in the form of a cock the plug i of which is provided with
a rose-head or other similar device. When the plug i is turned as indicated in
Figure 4 of the drawing, the straight jet is interrupted and tho liquid passes
through the rose of said cock, so as to produce a shower of the liquid.

mprovements in and relating to Apparatus for Projecting Liquids
under Pressure.
I, HERMANN SPAHLINGER, of Place Longemalle No. 1, Geneva, in the
Republic of Switzerland, Landlord of the Hotel du Lac, do hereby declare the
nature of this invention and in what mauner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to apparatus for the projection of liquids under pressure
and may be used for numerous purposes such for example as the extinguishing of
fires by means of a jet of water, or of a jet of water mixed with substances
intended to increase the extinguishing action of the same; the treatment of vine-
yards for the destruction of the mildew by means of the projection of a suitable
liquid and for similar purposes.
In the drawings accompanying my Provisional Specification,
Figure 1 is a vertical section showing by way of example, one form of apparatus
constructed according to my invention.
Figure 2 represents to an enlarged scale a section of the piston of the apparatus
shown in Figure 1 during its ascending stroke.

page_text: Figure 3 is a similar section showing the piston during its downward stroke,
and
Figure 4 is a section of a combined jet and rose.
A is a tank divided by means of a wall or partition B into two superposed
compartments A and A". The compartment A is provided with an opening a
closed by means of a cover C and adapted to enable the liquid to be projected to
be introduced into the said compartment A¹. The second compartment A' is
intended to receive the compressed air for acting upon the liquid contained in the
compartment A¹.
An air-pump composed of a cylinder D, a piston E and a valve F is secured to
the tank A in any suitable way and at any suitable point of the same, it may for
instance be located inside the said tank.
The interior portion of the oylinder D of said pump is connected with the
compartment A of the tank by means of a pipe in which is arranged a non-
return-valve F. The cover d of the pump cylinder D is provided with holes
intended to establish communication between the upper part of the piston and the
open air.
The piston E is composed of a caoutchouc-ring e fitted into the cylinder D and'
arranged somewhat loosely between two flanges e and secured to the shaft d.
The flange e is of such a shape that when the ring e is resting upon the Hange e³
(Figure 2) a circular channel is provided between said flange and the inner
circumference of the ring e. As the flange e is provided with a series of holes e³
arranged so as not to be covered over by the ring e the upper and under parts of
the piston are thus brought into direct communication with one another in this
particular position of the different paris; the latter will take said position
during the ascending stroke of the piston, in which the flange e³ carries the ring e
upward.
I wish it understood that I call this stroke "the ascending stroke" with reference
to the arrangement of the pump as shown in the drawing, and that the same piston
may of course be arranged horizontally or otherwise.
During the downward stroke of the piston (Figure 3) the flange moves the
ring e downward and the said flange e¹ having no apertures the piston will then
close the cylinder D hermetically.
It follows from this arrangement that the piston just described works as suction
and force piston, the non-return-valve E mentioned above, being only intended to
prevent the pressure which is accumulated in the compartment A³ from reacting
upon the underside of the piston during the upward stroke.
G is a tap intended both for letting out the liquid and for conveying the
compressed air from the compartment A2 to the compartment A'. The holes in
the plug of the said tap are so arranged that when the liquid coutained in A' is
prevented from coming out, the compressed air in A is also prevented from passing
through the pipes g and g' into the compartment A' and vice versa.
This arrange-
ment has a double object: 1st to produce a bubbling up of the liquid contained in
the compartment A¹ at the precise moment when it is to be thrown out, this being
of great importance when the said liquid is a mixture which must be thrown out
only after having been made homogeneous by stirring it up; and 2nd to produce
the projection of said liquid through the tap G the pipe H and the jet or rose
attachment by means of the compressed air contained in the compartment A².
The apparatus can be put under pressure and the cock G closed, so as to be
ready for immediate action when required, the tapacity of the compartment A³
being large enough to contain, if desired, sufficient compressed air to project the
whole of the liquid contained in the compartment A'. The air may be pumped
into the compartment A' while the cock G is open, if it is desired to maintain a
constant pressure upon the liquid.
The nozzle or attachment I is arranged so as to be adapted to produce either a
straight jet of the liquid or a series of jets as from a rose. For this purpose the
anid attachment is made in the form of a cock the plug i of which is provided

page_text: with a rose-head or other similar device. When the plug i is turned as indicated
in Figure 4 of the drawing, the straight jet is interrupted and the liquid passes
through the rose i¹ of said cock so as to produce a shower of the liquid.
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 :-
'
An improved apparatus for the projection of a liquid under pressure
characterized by:
1. A piston formed of a ring e held somewhat loosely between two flanges e
and the first one being formed so as to leave a free passage between itself and
the eaid ring when the latter bears upon the second flange, which is provided with
holes arranged so as not to be covered over by the said ring.
2. The cock G connecting the compartments A¹ and A' so that the compressed
air contained in the latter produces a bubbling up of the liquid contained in the
first one, at the precise moment when said liquid is allowed to escape.
