202 WAX AND COMB, 
by Professor Gerster, of Switzerland. The usual size of this 
is as follows: A can is made about one foot high, and the 
same in diameter, with suitable lid and handles. The 
bottom consists of a shallow basin or pan, similar to a 
pie-tin, made about 1 inch smaller than the can, with 
a rim 1 inch high. This is fastened near the bottom 
of the can, with arms, in such a manner that it stands at 
the distance of half an inch from all sides of the can, 
with one side a little 
elevated, so that the 
melted wax will run 
to one side, where a 
small tube or spout 
passing through the 
side of the can, is in- 
serted to carry it off. 
A basket of wire-cloth 
or perforated tin is 
made 1 inch smaller 
than the shallow bottom, and high enough to reach 
nearly to the top of the can. Three bearings are 
arranged on the inside of the bottom, upon which 
the perforated basket may rest, at a distance of */, inch 
from the bottom, and all sides of the can. This com- 
pletes the extractor, which is shown in figure 80. To 
render wax in this extractor, place it upon the stove, over 
a kettle partly filled with water, in the same manner as 
an ordinary kitchen steamer. Fill the perforated basket 
with the refuse comb or wax, cover tightly with the lid, 
and place a pan under the spout to catch the wax as it 
runs out. As fast as it melts, more may be added, until 
all is rendered. 
The second extractor (fig. 81), is one I have devised 
for my own use, which gives entire satisfaction. It is 
simply a tin can, 20 inches deep, and 12 inches in diame- 
ter, with lid and handles like the other. It contains two
