Referring now to the drawing, I have shown
10 my invention as applied to a dispensingv faucet
comprising a cast head I0 .having a pair of
intersecting passageways II and I2 therein, the
passageway II constituting a beverage dispensing
passageway provided with a discharge opening
15 at its lower end, and the passageway I2 con
stituting a guide-bearing for a reciprocable mem
pensing passageway II to atmosphere. As will
be apparent upon inspection of Fig. 2, the 1on
gitudinal movement of the reciprocable member
I3 in the passageway I2 controls the vent pas
sageways 21, the inner end of the member I3
moving across the passageways 21 so as to close
and open the same.
Adjacent its outer end the reciprocable mem 10
ber I3 is provided with _a slot 28 for receiving
a pin 29 carried by an operating handle 30, and
this handle 30 is pivotally supported on a pin
3I carried by an ear 32 extending outwardly from
the head I0. Preferably, the handle 30 is pro
vided with a slot adjacent its lower end for re
ber I3, the function and operation of which will . ceiving the supporting ear 32 and the outermost

In order to properly control the flow of bever

is disposed in the enlarged portion I6 of the sup

in sealing engagement with the sealing washer 20

passageway. This valve head 22 is hollow, as
shown in Fig. 2, and is internally threaded for

movement thus far obtained is not effective to
open the valve means. It will likewise be ob
served, however, that movement of the reciproca
ble member I3 to the position indicated by the
broken lines is effective to close the vent pas
sageways 21 so as to prevent leakage of bever

In order to limit positively the opening move

erably being threaìdedly connected, as shown. to
facilitate assembly of the parts I3, 22. 23, and 24
vin the passageways of the head Ig. The outer
most end of the rod 24 extends into the hollow
space within the valve head 22. as shownfand is
provided with a flange 25 which constitutes a
shoulder for abuttingly engaging the adjacent
end of the tubular valve stem 23, and the end of
the reciprocable member I3 from which the rod
24 extends constitutes a second shoulder 23 forV
abuttingly engaging the’opposite end of the tu

70 than the length of the tubular stem l23 so as to
provide a4 lost-motion connection between the

the shoulder _23 on the reciprocable member I3.
This shoulder 33, which forms a restricted por

serves to guide andsupport the outermost end
of thetubular valve stem 23, is cut-away adja
cent the bottom of the passageway as shown best
in Fig. 3, the cut-away portion being indicated 70
by the reference numeral 34. The purpose of this
cut-away portion 34 is to prevent the entrapmentof beer behind the shoulder 33 thereby to elimi
