12 Claims.
This invention relates to ?lter faucets and has
(of 210-47)
groove 23 of the supporting plate 2I and cooper
for :an object the provision of a ?lter which may ' ates therewith to bodily ?ex and clamp the gasket
be easily and quickly detached from the faucet to
permit'the renewal of the ?ltering medium with
:5 :out dismantling the faucet proper. With this
construction, the highest sanitary conditions may
be ‘maintained at all times with the minimum of
attention.
‘With the foregoing and other objects in view,
150 the invention will now be more particularly de
scribed, reference being had to the accompany
ing drawings, in which:—
‘Figure 1 is a top plan view of the ?lter faucet;
Figure 2 is a front elevation thereof;
Figure 3 is a vertical section taken on the line
3—3 of Figure 1;
‘Figure 4 is an enlarged detail of the regulating
member; and
Figure 5 is an enlarged fragmentary section
20 illustrating‘the clamping means for the ?lter.
Referring ‘to the drawings, the numeral I0 des
ignates generally a ?lter faucet having hot and
.cold-water inlets II and. I2, respectively, which
are ‘controlled by valves I3 and I4. Extending
25 inwardly from each of the valves are horizontal
passages I5 and I6 which merge centrally of the
?xture to form a mixing chamber ‘I ‘I. A common
‘outlet I8 communicates with the mixing chamber
I1 and interposed between the outlet and mixing
3 O chamber is a ‘vertically extending diverter valve
casing ‘I9 housing a diverter valve 20, the function
portion at of the ?lter ?lm between the support
and ?lter casing. Any desirable clamping means
may be utilized for this purpose and in the pres U!
ent instance there is illustrated a plurality of
wing nuts and bolts 33 and 34, respectively, en
gaging notched portions 35 and 36 in the‘ ?anges
22 and 3|.
,
With the construction thus far described, it will
be evident that the present invention entirely
eliminates the usual undesirable rubber gasket
between the sections of a ?lter casing.
In many
instances it has been found that these gaskets are
very unsatisfactory due to the fact that they per 15
mit bacteria to pass from the un?ltered to the
?ltered side of the casing. In the present inven
tion, this objectionable feature is eliminated by
utilizing the ?lter ?lm which, when clamped be
tween the ?anges of the support and casing, con 20
stitutes agasket which entirely prevents the es
cape of bacteria through the ?lter.
The ?lter casing is provided with an outlet
spout'3'l while’the ?lter support 2! has a centrally
located inlet 38 placing the interior of the ?lter
casing in communication with the diverter valve
casing I9.
The diverter valve may be of any de
sired construction, and in the present instance
top of the casing ‘I9, and preferably integrally
constitutes a double cone head 39 having spaced
valve portions 40 and AI adapted to engage valve
seats 42 and 43, respectively. The stem 44 of the
diverter valve projects through a wall of the outlet
I8 and has secured to its lower end an operating

In operation, and assuming that the diverter
valve is in the position shown in Figure 3, the
hot, cold, or mixed ?uids will pass to the mixing
chamber I‘I, into the valve casing I9, past the
valve 40 ‘and through the inlet 38 into the ?lter
casing 24, where it will then pass through the
_ ?lter and be discharged through the spout 31. If
ing exteriorly disposed lugs 29 for spacing the
un?ltered water isdesired, the handle 45 may be
‘?lter from the inner wall of the ?lter casing. The

off itsseat and subsequently seating the valve 40,
adapted to rest upon the support 2_I and to house
40 a ?lter 25 consisting preferably of three dome
shaped sections. These sections comprise a cen
tral ?exible ?ltering ?lm or liner 26 and inner
and outer relatively rigid foraminous supporting
inner and outer screens terminate at the open end
of the ?lter casing but the ?lter ?lm or liner 26
extends beyond the ends of the screens and forms
an annular gasket 30 which is adapted to be
clamped between the support and ?lter casing.
For accomplishing this, the ?lter casing is pro
_>_ vided withan annular ?ange 3| having an annu
"ra lar rib 32 which is complementary to the annular
thereby closing the inlet to the ?lter but per
mitting the water to ?ow downwardly through
the casing I9 where it will be discharged from the
outlet ‘I8.
In many localities where the water pressure is
quite ‘high, the force of the ?uid passing through
the inlet 38 would be too strong and cause incon

venience if some means were not provided to
?lter feed passage and engageable with said valve
seat in one position of adjustment.
3. In a ?lter faucet, the combination of a faucet
regulate the ?ow. Furthermore, the ?uid would
naturally impinge against the top of the ?lter
with the result that the side walls would not be
utilized to their fullest extent. Both of these ob
jectionable features are overcome in the present
construction by providing a regulating member
?xture having an inlet and an outlet, a valve
controlling the inlet, a diverter valve casing inter- 5
posed between the inlet and outlet, a ?lter sup
port comprising a. plate integral with and form
ing the upper wall of said diverter valve casing,
said wall having a ?lter feed passage therethrough
constituting a valve seat centrally disposed with 10
respect to said plate, a ?lter casing having an
outlet detachably mounted on said support, re
48 which functions both as a means for regulating
the ?ow through the inlet 38 and for effecting
10 an even distribution of the water‘ against the
walls of the ?lter. ‘Referring particularly to
Figures 3 and 4, the regulator consists of a sub
stantially ?at head 49 and a screw-threaded movable ?ltering means in said casing, and a re
shank 50 which is adapted to be threaded into ciprocating diverter valve controlling ?ow to the

49 may be positioned a predetermined distance a ?ange surrounding its open end, a rib projecting
outwardly from said ?ange, a support for said 20
20 from the inlet and the ?ow of water into the
casing is accordingly regulated. The under
casing having a port delivering to said casing and
surface of the ?at head 491 constitutes a ba?‘le
against which the water impinges as it passes
through the inlet, and it directs the ?ow uni
25 formly toward the side walls of the ?lter. Thus.
any variance in the water pressure of different
communities is readily taken care of and satis
factorily controlled as it passes from the diverter
casing into the ?lter casing, and by reason of the
provided‘with a ?ange having a groove formed
therein, a ?exible ?lter medium supported within
said casing and having an extended edge por
tion projecting outwardly between the rib and 25
groove, said rib and groove being of greater width
than the thickness of the ?lter medium whereby
the latter is bodily ?exed by said rib and groove
to provide a seal, and means'clamping the sup

tampering or accidental movement after it is
once regulated to the desired position in the inlet
passage. Furthermore, the large area of’ the
?lter is used to advantage by uniformly directing
the ?uid to the side walls of the ?lter and the un-g
desirable feature of constantly utilizing only a
small portion of the ?lter is eliminated.
*
It is, of course, necessary to renew the ?lter
40 ?lm or liner from time to time in order to obtain
the best‘results, and this is' easily and quickly
taken care of in the present invention. It is
merely necessary to unscrew the wing nuts and
lift the ?lter casing 24 off of its support. There45 after, the ?lter screens may be quickly detached
and the used ?lter ?lm removed. The newg?lm
may be easily slipped in place and the whole de
vice quickly reassembled with the extended por
tion of the new ?lter ?lm securely clamped be
50 tween the ?anges of the support and ?lter casing.
