Claims
We claim:
1. A device for cleaning a beer keg tap rod fitting,
said fitting comprising an elongated tap rod intake tube which is
open at its bottom end and which terminates at its upper end in a
threaded collar, a valve or pump, and an outlet tube,
said cleaning device comprising an elongated tubular housing
surrounding and enclosing said elongated tap rod intake tube and
terminating at one end in a threaded opening for receiving said
threaded collar and at the other end in a clean-out cap,
and means in said threaded collar for introducing a cleaning fluid
into said housing under pressure sufficient to force said fluid
around the underside of said valve or pump, downwardly through said
housing, around the outside of said elongated intake tube, and then
upwardly, then through said intake tube, threaded collar, valve or
pump, and outlet tube.
2. The device of claim 1 and means in said housing for dispensing a
chemical into said cleaning fluid flowing through said housing.
3. The device of claim 2 wherein said housing is a cylindrical pipe
which is co-axial with said intake tube,
said threaded collar being attached to the top of said cylindrical
pipe,
said intake tube depending from said threaded collar and downwardly
into said housing.
4. The device of claim 3 and means in the bottom of said housing
for dispensing said chemical.
5. The device of claim 4 wherein said cleaning fluid is water and
said chemical is sal soda.
Description
Our invention relates to a cleaning device for beverage dispensers
and more particularly to a device for cleaning a tap dispenser for
beer, or the like.
Beer kegs have standard size and shape openings for receiving taps
or pumps which are adapted to pump the beer out of the keg and into
any suitable glass, mug, pitcher, or other containers. After a
short period of time, the tap or pump collects sediment, becomes
fouled, and needs cleaning. This is not easily done since the long
pipe which projects down into the keg is an awkward shape and since
the pump parts are difficult to reach or clean.
Accordingly, an object of our invention is to provide a cleaning
device that is designed and adapted to fit any conventional beer
keg pump attachment.
Another object of our invention is to provide a device of the
character described which is easy to operate, without any special
training.
Still another object is to provide a beer tap cleaner that may be
used without requiring any special tools or equipment.
A further object is to provide a device that is actuated
exclusively by hot water under normal city pressure.
A still further object is to provide a tap cleaning device, into
which chemicals can be easily inserted, which is automatically
flushed during the cleaning operation.
In keeping with an aspect of the invention, an elongated housing is
adapted to receive the tap or pump used for dispensing beer from a
keg. Whenever the tap needs flushing and cleaning, it is placed in
a device that may be back flushed with hot water applied under city
pressure. A chemical, such as sal soda, or the like, may be forced
through the dispensing tube and pump or tap. The device is simple
in construction, economical to manufacture, yet highly efficient
for the purpose intended.
Other and further objects of our invention will become more
apparent as the description proceeds, when taken in conjunction
with the drawings, in which:
FIG. 1 is a vertical cross-sectional view of the device
constituting our invention having a conventional beer keg adapter
associated therewith; and
FIG. 2 is a lateral cross-sectional view of the inner tube of the
beer keg tap and the outer tube of the cleaning device at the line
2--2, in FIG. 1.
Similar reference characters indicate corresponding parts and
features throughout the views. More particularly, the character 10
identifies a conventional fitting for applying a beer keg tap to
the keg. The beer keg is not shown. The collar or fitting 10 is
equipped with a shut-off valve 11 which has an outlet tube 12 and
an operating lever 13. Or, the part 11 may be a pump operated by a
handle 13 for drawing beer from a keg. The bottom of the fitting 10
supports an intake pipe or tubular member 14 which extends
downwardly into the keg when the device is employed as a beer tap.
Thus, by operating handle 13, the beer is caused to flow up the
pipe 14, through pump or valve 11 and out the pipe 12.
The device constituting our invention includes a housing 15
designed to receive and threadedly engage the collar 10 at 16. An
inlet tube 17 threadedly engages the housing 15 at an inlet 18. The
bottom of the housing 15 threadedly supports an outer tubular
member 19 having an inside diameter which is larger than the
outside diameter of the intake tube 14 and longer than the intake
tube 14.
The lower end of the outer tube 19 is provided with a cap 20 and a
gasket 21 for sealing the tube 19. The gasket 21 is here shown as
being disposed between the cap 20 and the extreme lower end of the
outer tube 19. Obviously the method of attaching the tube 19 to the
housing 15 and the cap 20 may be in any conventional and efficient
means, such as the threaded means shown.
In operation, the device functions as follows:
The fitting 10 is first removed from a beer keg (not shown). The
shut-off valve or pump 11, the outlet tube 12, and the intake
tubular member 14 are removed as a unit. The entire assembly is
then inserted into the housing 15 with the intake tube 14 extending
downwardly into the outer tube 19. A predetermined amount of a
chemical, such as sal soda, is deposited in the bottom of tube 19,
as shown at 22. Hot water is applied under pressure into the tube
17, the housing 15, tube 19, tube 14, member 11, and tube 12, as
indicated by the arrows in FIG. 1. As the water flows downwardly,
it comes into contact with the chemicals 22, which forms a mixture
that is forced upwardly through the tube 14 and the valve or pump
11 and out the tube 12. This flow is disposed into a conventional
drain.
From the above description it should be apparent that the device
performs efficiently. Although we have shown a specific
construction of the parts and features, we are fully cognizant that
many changes may be made without effecting the operativeness of the
invention. Accordingly, we reserve the right to make such changes
as we may deem necessary or convenient. The appended claims are to
be construed to cover all equivalents which do not depart from the
spirit or the scope of our invention.
