MICHAEL FERTL in SCHWABACH i. Bavaria.

Patented in the German Empire on November 21, 1903.

The subject of the present invention forms a beer bung apparatus in which the Mercury serving as a sealing fluid in the lower part of a two-legged tube located. The aim of the innovation provided for this device is the movement of mercury, which by sudden and violent development of carbonic acid in the storage barrel connected to the loading leg of the apparatus is brought about, significantly to moderate and the through let the carbonic acid, which is stroking the relief leg, be blown off in a calm manner, so that a reading of each in the storage barrel

, .the apparatus is possible at any time. this is achieved in that partitions are built into the relief leg, which enforce it according to its full depth and not just throwing it upwards of the mercury, but also the rising through the relief leg Carbonic acid within the mercury lead in such a way that only a small part of the

Column is under the excess pressure of the withdrawing gas.

A beer bung apparatus of the new type is shown in the accompanying drawing in FIG. 1 and FIG. 2 shown in one embodiment.

As can be seen from this, a box b , which is tightly sealed on its front side with a transparent plate a, is inserted into two tubes connected to one another through the opening e by a connecting tongue d extending up to near the lower wall c. respectively g divided, which in their lower part take up the mercury serving as the sealing fluid.

The loading leg f of this two-legged tube is connected to the drum through the opening h , while the relief tube g is provided near its upper end with a known end piece i , which allows the carbonic acid to escape but holds back mercury or impurities. In this relief leg g , inclined partitions k are installed in such a way that they protrude somewhat from the side walls. The proportions of the two pipe legs are dimensioned so that the cross section of the loading leg is the same size as the clear cross section of the relief leg. Instead of arranging the loading and relief legs next to one another, the modification could of course also be made so that the two legs lie one behind the other and are connected to one another through an opening penetrating the partition.

In the embodiment shown, the partitions k are arranged in two rows running diagonally upwards towards the central axis of the relief leg, which are offset from one another by almost half the distance between the individual partitions of each row. These inclined walls are bent in the vertical direction near the walls of the relief leg g , so that an extension /

arises. The even and calm overflow of the pressurized carbon dioxide from the load into the relief leg is achieved in a simple manner in that the tongue d protrudes into the middle of the relief leg by means of an upwardly sloping shoulder m. In the case of one that occurs in a barrel ίο violent development of carbonic acid, the mercury in the loading leg is pushed so far into the relief leg that the carbonic acid. along the approach m the tongue can pass into the relief leg. The mercury pushed over, however, finds a sufficiently large resistance on the many partitions built into the relief leg, which it must alternately flow around when climbing up, which is sufficient even with violent development of carbonic acid in the bungee barrel, the pressure equalization in the loading and relief leg goes on smoothly and without violent surges of the mercury allow. Since the escaping carbonic acid flowing through the relief limb is carried up through the septum in its center, it only sets the middle part of the mercury column in motion, while the larger mass of mercury behind the septum remains at rest and thereby continuously counteracts the pressure in the relief limb. In this way, the apparatus works completely smoothly and the prevailing pressure can be read off at any time, even when it is fully active. Godfather ν τ-An Proverbs: i. Box-shaped, two-legged mercury bung apparatus, characterized by inclined partitions (k ) built into the relief leg (g) , arranged in staggered rows, overlapping one another, which penetrate the relief leg (g) over its entire depth, but protrude so much from its side walls that They prevent the mercury flowing around them from being thrown up and the carbon dioxide flowing upwards only in one part of the final mercury column in a zigzag fashion. 2.
