92 VINEGAR, CIDER, AND FRUIT-WINES. 



A channel for the conveyance of the warm air from the heat- 

 ing apparatus in the cellar to and distribution in the workroom. 



An apparatus for heating the alcoholic liquid. 



The three reservoirs rest upon the joists of the ceiling of the 

 workroom, a small chamber inclosing them being constructed of 

 papered boards. In the floor of these chambers is a manhole by 

 which the reservoirs can be reached. This manhole should not 

 be provided with a door, it being of importance that the reser- 

 voirs should be constantly surrounded by warm air which as- 

 cends through the manhole. To prevent loss by evaporation the 

 reservoirs should be provided with well-fitting covers. 



To retain solid bodies such as shavings, flakes of mother of 

 vinegar, etc., which might eventually obstruct the fine apertures 

 in the false bottom or sparger, a filter is placed on the end of the 

 pipe through which the alcoholic liquid passes into the reservoirs. 

 A suitable filter for the purpose is a horse-hair sieve containing a 

 linen bag, the latter being from time to time replaced by a new 

 one. 



The conduits for the conveyance of the alcoholic liquid to the 

 distributing vessels and from there to the generators are best con- 

 structed of thick glass tubes, the connection of two pieces being 

 effected by pieces of rubber hose pushed over the ends and se- 

 cured with twine. 



Each generator may be furnished with a vessel containing the 

 automatic arrangement, it being, however, in this case necessary 

 to provide for each a special conduit from the reservoir, which for 

 a factory containing a large number, of generators is rather ex- 

 pensive. Hence it is recommended to use for each group only 

 one or at the utmost two distributing vessels, and from them to 

 extend smaller conduits to the separate generators. Each of the 

 principal conduits is provided, at the place where it enters the dis- 

 tributing vessel, with a cock, which is adjusted for the discharge 

 of a certain quantity of alcoholic liquid. If, as above mentioned, 

 every generator is to receive an affusion of 5 quarts of alcoholic 

 liquid every 30 minutes, the distributing vessel serving for a 

 group of 8 generators must have a capacity of 40 quarts, and 

 the spigot has to be so adjusted that exactly this quantity passes 

 through it in 30 minutes.
