QUICK PROCESS OF FABRICATION OF VINEGAR.

Fig. 7, by a glass tube, which bends upwards nearly as high as 

 the air-holes and then curves downward so as to discharge the 

 liquid, when it rises as high as the shelf in the interior of the 

 apparatus, into an appropriate vessel placed to receive it. Simple 

 as this arrangement is, it is scarcely suitable in the practice on 

 account of its being too liable to breakage, and hence it is better 

 to provide the generator with an ordinary spigot, and prevent the 

 vinegar from rising too high, by boring about J inch below the 

 draught apertures a hole in which is fitted a pipe leading to a 

 tub. The vinegar rising to the height of this pipe will commence 

 to run off, and thus give warning to empty the generator by 

 opening the spigot. 



In generators of older construction a strong hoop is fixed about 

 one foot from the top, on which is placed a perforated disk which 

 serves for distributing the alcoholic fluid as uniformly as possible 

 over the entire filling. The disk, Fig. 8, is perforated with 

 numerous holes (about 400 with a disk diameter of 3 feet)

arranged in concentric circles. These holes are loosely filled with 

 cotton wick or packthread, a knot being made at the top end to 

 keep them from falling through. The threads pass down to the 

 shavings, and serve the double purpose of conducting the liquid
