This invention relates to means for drawing
beer from barrels, kegs or the like, and is partic
pipe 'I for supplying air orgas under pressure to
the interior of the barrel. The tap also has va
ularlyintended as an adapter or attachment to
be used in connection with beer tapsor as a part
" '5 of such taps. Taps are well known and aremade
locking nut 8 for attaching it to the barrel fitting
inra variety of forms. 'I‘hey provide means for
" admitting air or gas under pressure to the barrel
for forcing out thebeer or other liquid and also
provide means for inserting a >tube or pipe com
monly, known vasa r“tapl rod orV tube” intoV the
fbarrel .for lwithdrawing the _beer therefrom, .such
tubev ¿being usually connected ywith a pipe or hose
leading to thecooler. 'I‘he pipes or conduits lead
n ing from the beer barrel, including vthe cooling
10Vcoils, shouldbe Vfrequently,cleaned in order to
providegood clean beer. It is possible to vclean
thecoils even whenv the beer-.barrel isA under pres
sure, by shutting 01T vthe tap rod valve and dis
connecting .the„hos,e. therefrom. Consequently
zocthisis `often .done and the tap rod `is left without

with the, present invention I provide means

improved adapter or device for accomplishing the
30 above purposes in a simple and eñicient manner;
to provide an adapter or attachment which may

and unobstructed interior so that bacteria will
40 not be apt to collect therein andalso so that the
device may be readily cleaned or sterilized and
to provide such other advantages and improve
ments as will appear more fully hereinafter.
In order to prevent discharge of gas or liquid A30
from the barrel, the valve body has a valve seat
I9 at the top thereof which is adapted to be en
gaged by a ball 20 when the valve rod is removed.
The ball 20 may be made of cork rubber, rubber
¿composition or any other suitable material, pref- 35
erably of a light and yielding character so that
it may be readily forced against the seat I9 by
the gas pressure.
The valve body I4 has a lateral projection 22
which forms a side chamber or recess for receiv- 40
ing the ball 20 when it is out of closing position.
Curved side rails or guides 2l serve to guide the
ball from its closing position as shown in Figure
2, to its normal or inoperativeposition as shown
in Figure 1. The projection 22 is threaded to 45
In the accompanying drawing illustrating a
commercial form of my invention,

'I‘he barrel 4 is shown with a tap 5 of any ordi
nary or preferred form of construction, this tap

removed as for cleaning or the like.
When the keg 4 is tapped and the tap rod I3
inserted in theusual manner the packing I0 is 50
tightened andV air or gas under pressure may be
admitted through the supply pipe or hose 1, thus
placing pressure on the contents of the barrel.
The beer or other contents of the barrel may then
be drawn 01T through the tap rod and out through 55
the pipe 25 being controlled by the valve 24.
When it is desired to clean the tap rod or con
duits connected therewith, the packing may be
loosened and the rod withdrawn and ther-eupon
