FIGURE 1 is a vertical axial cross-section view show
ing one form of a coupler constructed in accordance with
this invention and illustrating a faucet aerator to which
the coupler is adapted to connect, the faucet aerator being
at a discharge terminus ‘of a faucet in a kitchen, or the
like;
This invention relates to a combination coupler, and
more particularly relates to a coupler adapted "both for
connection to a water-utilizing appliance and ‘for dispens
ing potable Water therefrom.
'
Couplings are presently used for the connection of a
portable dish-washing machine, or other water-utilizing
appliance, to a faucet in a kitchen, and usually such a
coupling is arranged so that the used-water being dis
charged from the Water-utilizing appliance is discharged

of a modi?ed construction of a portion of the device
shown in FIGURE 1; and
FIGURE 3 is a vertical axial cross-section view of
another form of coupler constructed in accordance with
this invention.
Referring now to the drawings, there is shown in FIG
URE l a faucet aerator generally indicated at 10, which
would normally be provided at the discharge end of a

As has heretofore been pointed out in our co-pending

provided a pressure condition which could result in back
?ow of water under pressure from the coupler, so that
such pressurized water would tend to squirt in unre

the source of liquid.
In our said co-pending application we have also dis

end of which is provided with coupling elements adapted

to connect the coupling body 16 to an appropriately
shaped Water discharge device, such as may be provided
by an exteriorly grooved faucet spout, or as provided

While the details of connection of a coupling of the

so as to avoid the said problem incident to uncontrolled

that the coupling body 16 de?nes at the upper end thereof

is being removed from the source of liquid under pres

It will be understood that when a dish-washing machine
or other water-utilizing appliance is being used in a
kitchen with a coupler attached to the faucet, the faucet
is thereby occupied, so that in the event a person wants
to take a drink of water, he is unable to do so unless he
uncouples the coupler from the faucet. The provision
of a bleed means, as disclosed in our co-pending applica
tion, might appear, at ?rst blush, to provide a satisfactory
means for bleeding drinking water from the ‘coupling
which could be captured in a drinking glass or the like.
However, the discharge of bleed water from the coupling
of our co-pending application causes the water to pass
through a portion of the coupling which is generally used

such as groove 12 in aerator 10. The coupling balls 2!}
are positioned in tapering recesses and the balls 20 pro
trude radially inwardly a distance suf?cient to enter recess
12 to effect desired coupling between the parts. The
balls 20 are normally pressed inwardly by a selectively
retractable sleeve 24 that is spring~biased by coil spring
26 to the position normally seen in FIGURE 1. Coupling
body ‘16 carries a removable snap ring 28, which limits
the retractability of the sleeve 24; and the shape of sleeve
24 is such that, While permitting retraction of balls 20
to permit coupling, the balls 20 are at all times retained
in recesses 22.
The coupling body 16 is provided, at the lowermost
