Description of the Extractor. 93 
Round these uprights, from the top down- 
wards, some thin, but strong, twine should be 
wound, a small space being allowed between 
each row. This string serves to hold the comb 
in its place, which otherwise would be thrown 
out by the centrifugal force ; at the same time 
it allows sufficient space for the honey to pass 
through. 
In order to keep this twine in its place, 
small pins should be driven into the up- 
rights. They should be close to one another, 
and should project as little as possible from the 
woodwork. 
Galvanized netting may be used as a sub- 
stitute for the twine, and if this is nailed to 
the uprights, there will be no need to bind them 
together with the rods mentioned above. In 
the upper part of the axis, just below the cross- 
bar, there should be a groove, or fixed wheel, 
about three and a half inches in diameter. 
On the edge of the tub, at an equal distance 
between the two uprights, a piece of wood 
should be solidly fixed, projecting about two 
inches above the rim. On this revolves a 
wheel about one foot in diameter, connected 
with the groove in the axis by a strong cord.
