Improvements in Hydraulic Filtering Valves and Regulators.
We, RICHARD KRIX and FRANZ KORWILL, both of No. 15, Rennweg, Vienna III,
in the Empire of Austria-Hungary, Merchants, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to an apparatus, which, being inserted into water pipes
or conduits for instance at the various discharge cocks thereof, serves to purify
the passing water, to admit of the latter being discharged in a steady flow and
to simultaneously prevent the water from flowing backward on closing the cock
thus preventing rupture.
An apparatus of this kind is represented in the accompanying drawing, in
which:
Figure 1 is a longitudinal section representing the tubular connection.
Figure 2 is an exterior elevation of the water waste preventer, and
Figure 3 shows the valve body, separately, in side elevation.
The apparatus consists of a cylindrical metal body a, on the one end of which
the valve cone e of star-shape in cross section is arranged, upon which an india-
rubber disc f is fixed, which is on its part reinforced by the metal disc h, fixed
thereto by a screw nut m. The free inner space of the cylinder a is filled with
two or more layers of porous material b, leaving the chambers c between them
and held in position by the traversing screw 9 and the cross piece d. The said
valve body is displaceably located in a metal piece or union k being on one side
provided with internal screw threads and on the other side with external screw
threads, into and over which said screw threads the tubular connecting pieces B
and A are screwed.
The apparatus operates in the following manner:
arrow, traverses the valve
The water flowing in the direction indicated by the
head e, enters the interior of the valve body, passes through the layer or layers
of filtering material band is discharged through the joining tubular connection
or nozzle. If the discharge or connecting piece or nozzle is screwed off, no
special cock is required for cutting off the water, because the cylinder a-by the
aid of the india rubber disc f-automatically shuts the discharge opening by the
action of the water pressure.
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 :-
A device for regulating the flow of water in water supply pipes and meters,
for preventing rupture of the supply pipes for automatically closing the latter,
and for filtering the discharged water, the characteristic feature of the device
being a cylindrical body a arranged in a metal body or union k and having its
interior provided with a layer or layers of filtering material b; this said cylinder
carrying upon one side the valve head e, to the top of which the closing or tighten-

page_text: ing disc f, surmounted by a reinforcing disc or plate h, is secured, the object
of the device being to filter the water by causing it to traverse the filtering
material and to thus simultaneously ensure a steady flow of the discharged
water; to further obtain an automatic "cut off" of the water when the discharge
nozzle or connecting piece is removed and to finally prevent the running water
from flowing backward, thereby protecting the water meter or discharging
device from being ruptured.
