1, RICHARD STIPPERGER, of 24 Stubbenhuk, Hamburg, in the Empire of
Germany, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a mouth-piece or nozzle provided with a self-acting
valve for hose and other pipes for supplying water or other fluids under pressure.

Figure 2 a transverse section of the hose-valve.
a is an externally grooved metal tube, which is adapted to be inserted into
and secured in the end of the hose, so as to serve as a connecting-piece between
the hose and the mouth-piece or nozzle m. The tube a is closed at one end by a
partition 6, which is provided with an aperture serving as a seat for the valve c.
The valve c is so arranged as to be automatically pressed against its seat by the
water.
When it is desired to open the valve, pressure is applied on opposite sides at the
outside of the elastic walls of the mouthpiece or nozzle m whereby the rods d and
with their joints f,g and h, are moved into the position shown in dotted lines

the passage of the water can take place. serve as shoes to bear against the
sides of the mouth-piece or nozzle. The automatic closing of the valve takes place
immediately on removing the external pressure from the sides of the mouth-piece
or nozzle.
This valve is also adapted for use with a mouth-piece or nozzle made entirely of
metal, in which case the system of levers d, e can be operated by suitably-packed
pressure-pins passing through the sides of the said mouth-piece.

COMPLETE SPECIFICATION.
Improvements relating to Mouth-pieces or Nozzles for Hose and
other Pipes and to Self-closing Valves therefor.
I, RICHARD STIPPERGER of 24 Stubbenhuk, Hamburg, German Empire,
Merchant, 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 a mouth-piece, or. nozzle, provided with a self-acting

page_text: valve for hose and other pipes for supplying water or other fluids under pressure
and to a modification thereof being a closing device (valve) for water hose of all
kinds but more particularly for those used with syringes.
In the accompanying drawing:
Fig. 1 is a longitudinal section
Fig. 2 a transverse section of the hose valve on the line of Fig. 1.
A modification thereof is shown in the Figs. 3 to 5 and
Fig. 3 is a transverse section of a closing-device for syringes on the line
Fig. 4,
Fig. 4 is a longitudinal section and
Fig. 5 is a transverse section on the line z z of Fig. 4.
yy of
(a) is a tube of metal or other material, which is adapted to be inserted into
and secured in the end of the hose, so as to serve as a connecting-piece between
the hose and the mouth-piece or nozzle (m). The tube (a) is closed at one end
by a partition (b), which is provided with an aperture serving as a seat for the
valve (c). The valve (c) is so arranged as to be automatically pressed against its
seat by the water.
When it is desired to open the valve, pressure is applied on opposite sides at
the outside of the elastic walls of the mouth-piece or nozzle (m), whereby the
rods (d) and (e), with their joints (f, 9 and h) are moved into the position
shown in dotted lines, Fig. 1, and the valve likewise takes up the position shown
in dotted lines when the passage of the water can take place. The pieces (k, k)
serve as shoes to bear against the sides of the mouth-piece or nozzle. The
automatic closing of the valve takes place immediately on removing the external
pressure from the sides of the mouth-piece or nozzle. The automatic closing of the
valve when not in use may be affected by a spring or similar elastic device acting upon
the valve.
It is not necessary that the middle axis of the valve is identical with the middle
axis of the hose or tube; they can, if desired, be placed at right angles to each
other, or in any other suitable manner.
The valve of the closing-device for use with syringes, shown in Figs. 3 10 5,
remains closed by the influence of the water pressure, and when desired, can be held
open only by continued side-pressure in a proper manner from outside.
In order to apply this apparatus to syringes it is only necessary to attach to the
syringe the part of the hose in which the arrow is show in Figure 4.
The part of the hose which lies beyond the ring (r), looking in the direction of
the arrow, thus forms the mouthpiece of the hose from which the water issues, this
being so whether the stopper or valve (n) lies above or below the ring (7). In both
⚫ cases the stopper or valve (n) stops the flow of the water if no sidewise pressure be
applied to the hose from the exterior.
-
Inside of flexible hose (o), made of hemp, iudia-rubber or any other suitable
material, a ring (r) is firmly fastened to the sides, just below the orifice; this
ring (r) may better be described as a cross-piece (r) of the saine material as the
hose) with a hole in the centre. The width of the hole must be in accordance
with that of the orifice. Above this ring (r) and exactly in the axis of the hose,
a valve or stopper (a) of cylindrical or slightly conical shape is held in position
by means of supports (p), attached to the sides of the hose (o), so that the hole
in said cross-piece is normally closed by the valve or stopper (n). The stronger
the water-pressure in the hose (o) the tighter the ring will press on the
stopper (n).
When the hose is pressed from outside in the space between the cross-piece (r)
and the supports (p), the hole in centre of said cross-piece (7) loses its circular
form, and detaches itself partially from the stopper (n), thus allowing the water to
pass through.
Of course the stopper (n) may be equally well arranged below the ring (r), that
is to say in the space between the inlet orifice and said ring.

page_text: 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. The combination of a mouth-piece or nozzle for hose and other pipes, with a
self-closing valve consisting of a tube (a) between hose and mouth-piece with a
partition (6) and valve (c), opened by the change of position of an interior lever-
system on the walls of the elastic mouth-piece being pressed together, substantially
as hereinbefore described.
2. The combination of a self-closing valve as described in Claim 1 with a spring
or similar elastic safety-device acting upon the valve, substantially as hereinbefore
described.
3. The combination of a self-closing valve with a flexible hose (o), Fig. 4, and
a cross-piece (7) therein, with a hole in its centre, normally closed by a valve or
stopper (n) but opened by a pressure from outside in the space between the cross-
piece (r) and the supports (p) thus allowing the water to pass through, substantially
as hereinbefore described.
