as did the Introduction Of the patent
Creamery which several years ago dis
pensed with the tedious hand Swimming
process.
This wonderful machine ia called the
butter extractor and was invented and
patented two years ago by O. A. Johansau
OF Stockholm, Sweden. It has been
thoroughly tested in the Old World
BY both scientific and practical mashods

notice OF the scientific world, although il
Inns passed the experimental Htape The
machine iteelf ia quite small and simple
when the duel nature OF its work is con.
tidered, being only slightly larger than
the centrifugal Heparators which nra now
uded In creameries, but which accomplish
only the gensration of the cream from
The milk. This goes still further, and in
tho same operation churns the cream,
producing butter, it ia claimed, more
economically than by tine old way. The
extractor, closely resembling the sepa-
rRtor and Running ut about the same
speed Il. e., . 600 revolutions per minute),
takes about 800 pounrH OF milk per
hour and produces one pound of butter
per minute.

gradually sinks down inside OF the rim
OF the drum, and as it is acted upon BY
the centrifugal force, the specifically
lighter butter globules are forced toasti
the csntre and are crowded mp against
the wall OF the inner drum This latter
ia 30 arranged that ii is not until the very
richest part of the milk has been forced
TO the top that II can overflow the rim OF
the inner drum and come in aontso. with

saves of the wheel thus produce SUI

the butter gobules to separate and allow
