My invention relates to beverage dispensing and
measuring valves and has particular reference to
valves used in connection with containersfor
beverages which are dispensed in accurately
5 measured quantities or portions.
My invention has for its'object to provide a

the upper valve so that it can be raised and there
by opened by manually raising the vent tube, the
bottom valve remaining open.’ With bothvalves

Still another object of myinvention is to ar
deliver measured quantities of a beverage such
range the valve parts so that they can be easily
removed fromnthe casing for washing and clean- '
ing, leaving the casing open from both ends also
as cream from a container.
For this purpose I
provide a tubular. casing extending vertically
downward from the bottom of a container and
having a valve on top for admitting a liquid from
the container into the casing. The casing has
another valve at the‘ bottom so arranged that it
15 can be opened only ‘when the top valve is closed
and the top valve can be. opened’ only when the
bottom valve is closed. 1 I also provide the casing
with a manually operable lever connected with
for cleaning and washing.

it can be raised either by lifting its end or by
thepressure from underneath on its portions at’
the sides of the casin'g'as, for instance, by press
ing on it upwardly by the rim of a cup or glass.
I also provide a spout in ,the lower valve for dis-_
35 pensing the liquid, the spout being of- such a shape
that itcan be raised by a narrownecked recepta-v
cle for ?lling the same with the liquid.
'
Another object of my inventionis'to provide
a vent tube extending from the ‘casing to‘ the up
40 per portion of theecontainer above the normal
level of the liquid therein in order to facilitate
?lling of the casing with vthe liquid by providin
escape for the air in the "casing. .
'
Anotherobject of my 'invention is to provide
45 means to prevent ‘dripping “of the liquid from the
casing after it has bee'nemptie’d from the main
body of the liquid. For this purpose I-provide a
valve in the vent tube so connected'with theibot
tom casing ‘valve that the vent valve is closed‘
50 when the bottom valve is opened thereby shutting
off the escape of air from thecasing and thereby
stopping any dripping through the bottom valve

Another object of- my invention is to provide
65 means for rapid emptying of the container when
between‘ the container and shell being ?lled with
a heat insulating material 4 such as rock wool,
asbestos, etc. The ‘container-V2‘ is closed on top
with a cover 5‘, a tray 6'for ice or similar cooling
medium being supported under the cover 5. The
container 112.53, bracket 1 at the side supported
on a standard _8 extending from a base 9 for re
ceptacles such as cups, glasses, bottles, etc. The
upper end of the casing I has a valve seat for a .
valve l0. .A 'tubular‘rod H extends downward
from the valve“! and has a plunger l2 at the
lower end‘s‘lidably ?tted in the casing I. The
plunger has a central opening I3 with a valve seat
underneath which'can be closed by a valve I4
extendingfrom a hollow plunger l5. The lower
end of the valve plunger [5 extends outside the
casing I and has an annular groove l6 engaged
by a lever H.‘ The latter extends in either di
rection from- the member l5 and rests on T
shaped members l8 rotatively supported on the
ends of a yoke I9. In the embodiment shown
in Fig. 1 the lever is formed 'of two rods connected
at the ends and spaced apart so as to form slots
slidably ?tted over the central portions of the
T-shaped members and ends of the yoke, the T
members being threaded on the ends of- the yoke
so that they can be turned sidewise when it is
desired to remove ,the lever with the plunger 55

screwed on the threaded end of the casing and
resting against the lower end of the outer shell 3.

continue downward through the open valve in
the plunger I2 into a receptacle underneath.
The ?ow will continue uninterruptedly until the
container 2 is emptied’ or until the valve In is
again closed.
’
For cleaning the valve the parts I0 and I3 can
be completely withdrawn from the casing I
A tube 23 is ?tted in the valve. I0 and extends
10 up to the top of the container 2 vabove the normal
through the top, and the valve I4 with the plung
level of the liquid and is in communication with
the space in the casing through‘ ducts or Chan-s
nels 24. A valve 25 closes the upper end of the
tube 23 and has a rod 26 extending into the
15 tubular rod I I where it is of a larger ‘diameter
and is slidably ?tted in the bore of the‘ rod II.
The lower end of the enlarged end 21 of the rod

sidewise to allow them to pass through the

glass which it is desired to ?ll. These’operations
can be easily performed since bothendsof ‘the
lever arevfree to move upward on the T-shaped
end pieces and ends of the yoke I9. The object
35 of_ such movements is to raise the bottom plunger

ing'a bottle or similar receptacle against the
spout at the end of the plunger, I5 provided the
neck of the bottle is smaller than. the end of
