PATENT OFFICE.

With the increasing consumption of bottled beer, there is a need for an apparatus entered, by means of which the beer was removed from the containers without reducing the quality, in particular can be drawn off on bottles without loss of carbon dioxide and also without loss of quantity. It is from this Basically a number of bottle filling machines have already been designed which meet the requirements are not completely sufficient, and which all show more or less deficiency, in that either the Carbonic acid is not preserved or the construction of the apparatus is too complicated, they are difficult to clean, sometimes require excessive pressure, or the outgoing Recirculate the compressed air and the resulting foam into the inflowing beer.

These deficiencies are eliminated by the present bottle filling apparatus, and it is at The construction of it also takes into account the results of investigations which was carried out by the Berlin Research Institute for Brewery on bottled beers have been made, and which have shown that the taste and durability the bottled beers can be increased considerably by the fact that the each time Prepare a fresh bottle to avoid foaming applied counter pressure stajt ^ .wje, ,,, so far ,, through, tested air is produced by means of a carbonic acid apparatus, so that the beer can be further impregnated is achieved with carbonic acid. Of course, the device can also be used of pre-filled air, and this method is to be used especially when the bottle filling device in direct connection with the storage tank and the filter switched on in between is brought. In this way, the overfilling of the beer into the Shipping fafs avoided carbonic acid loss, then it is also put in the bottle A long-life beer is filled, according to the existing beer from the lager to the bottle Counter pressure retains its full body.

The accompanying drawing illustrates in Fig. 1 in vertical section, in Fig. 2 in the horizontal Section through an apparatus which is set up with two according to the present invention Filling taps is provided.

The housing A of these filling taps contains the inlet port α for the carbon dioxide or pre-filled air, the outlet b for the mixture resulting from the carbon dioxide and the air in the bottle and the beer inlet c. The cock plug B contains a central bore d, which opens out into a tubular extension e below, and from which a horizontal channel a ¹ and a 1 respectively at the level of the connector α and b. b ^l goes out. ^{A helical channel c 1 is} cut into the surface of the plug, which. above can be associated with the beer inlet c

and opens out into a tubular extension f of the tap housing A at the bottom. The central bore contains an enlargement g, which is delimited at the bottom by the tubular extension piece e drilled through in the center. The bore ά ^{Λ of} this extension piece e is slightly widened at the top and is provided here with a nut thread into which a pin h is screwed, the head i of which is formed by a bowl-like extension. Grooves h ^{1 are} cut into the surface of the pin h (see FIG. 3). Furthermore, since the pin h is not screwed in so deeply that it ^{could close the bore d 1} , for example, the connection between d and d ¹ remains secured through h ^1.

In the bowl-shaped head i lies a ball k which floats up and finally closes the lower mouth of the channel d as soon as the widening g fills with liquid. So that the ball k also securely closes the channel d , the upper wall of the extension rises towards the channel d .

The two inlet nozzles α for the carbon dioxide or pre-filled air can be connected to a common tap C by hoses or pipes.

The handling and mode of operation of the present filling device is as follows:

The bottle E placed on a plate D is pushed by pushing up the plate with the neck over the attachment f of the tap housing until it seals against a rubber plate F attached to the tap housing. The cock plug B is in that position which is illustrated by the filler cock /, ie all three lines α b and c to the bottle are shut off. Now the cock C located in the carbonic acid line α is opened and the plug B is slowly rotated 90 ° by means of the handle. During this rotation of the plug, the channel a ¹ comes into connection with the channel α (Fig. 4), so that the carbonic acid with the pressure on it through d into the expansion g and from here through the channels h ^l and the bore d ¹ penetrates the bottle, praises the air it contains and mixes with it somewhat. In consequence of the higher specific gravity of carbonic acid, however, it will fill more of the lower part of the bottle, while the lighter air is expelled upwards. So there is definitely an increased pressure in the bottle.

As already mentioned, the cock plug B is turned evenly further, so that the same now, as soon as the channel a ¹ has exceeded the opening of α , again closes all three channels α b and c for a while.

If the plug B is ^{turned 90 0} , the channel b ^x connects to channel b and channel c ¹ connects to the beer supply line c. The latter is open so that the beer ^{can enter through c 1} and the tubular extension /. The counter pressure in the bottle prevents the beer from foaming. So that the beer is fed in in a calm manner and the counterpressure cannot escape, the air outlet cock G is opened only a very little, so that the air mixed with part of the carbonic acid can escape only to the extent that the bottle does with it, without a decrease in pressure Beer fills. Instead of this tap G, an adjustable valve can also be switched on, which opens automatically to a greater or lesser extent according to the pressure existing in the bottle.

The air flow going up around the bowl i can never rip up the ball resting in the bowl, so that the channel d would be blocked, whereby the inflow of beer would be immediately interrupted. Only when the bottle is completely filled and the beer now passes through the channel d ^x and the grooves h ^l into the extension g and fills the same, the ball k floats up and now closes the channel d, so that on the one hand the further inflow of Beer is interrupted and, on the other hand, any loss of beer is prevented. Just as little can the carbonic acid entering through the channel d before filling also ripen the ball downwards and bring it in front of the opening of the channel d ^l , which would occur if the bowl-like insert were not present.

It is evident that as a result of the intimate contact of the inflowing beer with the in the carbonic acid in the bottle is absorbed by the beer, so that the carbonic acid content of the beer is thereby increased.

When the bottle is full, the stopcock B is turned back to its original position; Here, however, there is a moment in which the compressed air or the carbonic acid pressure is applied to the beer in the filled bottle, but this is of no importance.

When the apparatus is not in use, it is advisable to close the opening for the beer outlet at the lower end of / with a nut screwed onto the lower, slightly protruding end of the attachment e , so that no dust can penetrate into the casing of the stopcock.

Claims (1)

Patent claim: In the case of beer filling machines that work with counter pressure, the extension (g) in the duct (d ¹ d) of the filling tap, which is used for the escape of air and possibly also as a supply line for the carbon dioxide or compressed air, in connection with the bowl-like insert ( i) with ball (k) such that neither the ingress of carbon dioxide or compressed air, or the stripper air or the gas exiting the ball (k) mitreifsen and thereby the channel (dd can shut off ¹ J, a barrier rather only occurs when the bottle is filled and the beer has risen to the extension (g) if the tap is not turned off in time.
