Many schemes have been devised for
the automatic or mechanical milking
OF cows.
.One after another they have been
tried, and found wanting aud discard

practice OF forcing tube into the te at

the result that the animals subje cted

their milk. In most OF them the milk

principle. by reducing the pressure

construction. Tho pail is cylindrical
I'm form, with truncated conical top.
It's opening. which is four inches wide.
Is closed by means OF thick glass
disk. which rests inside flush with the
outer rim OF the pail. supported by n
thick rubber b.nd, held in place by
projecting ledge underneath. On one
side OF the shoulder OF the pail is the
nozzle which has been referred TO, aud
on the opposite side are four similar
MOBILES. all OF which are like the
small connections upon the iron pipe.
The solitary nozzle Is for attachment
TO the long flexible tube from the ir on
pipe; the other four are for short
lengths OF tubing, connected in their
turn with specially constructed teat
cups, each OF which receives teat OF
the COW under operation. The cups.
like the pail. are made OF timed iron
and each one is provided with tap
or stopcock. Tho milk pail has, in
addition 10 It's handle. n couple of
hooks. by means OF which IL is sus-
pended little in front OF the cows
udder. broad band OF girthing being
laid across the animals loins for the
purpose.
THE modus operandi Is very simple.
When IL is ready the pump Is worked
by a lad. and the air Is thus exhausted
from tho iron pipe. Then pail. with
its teat cups attached, is adjusted I'M
der the COW. the long tube is joined 10
one of the connections overhead. the
stopcock Is opened. and partial
vacuum Is established within the pail.
Next one OF the teat cups is moistened
and placed so as 20 embrace the teat;
the stopcock OF the cup is then opened.
the teat Is thus brought under the In
fuerce OF the vacuum. and the greater
external atmospheric pressure at once
causes the milk TO flow. After all four
teat cups have thus been adjusted. four
Jets OF milk can be seen flowing into
the can Immediately beneath the glass
cover. Ia from eight 10 ten minutes
the COW Is MIXED dry and the stop
cock OF the connection on the iron pipe
being turned of. the long India rubber
tubo Is detached from the pail. thus
destroying the vacuum. The pail with
its teat cups Is taken away. the milk Is
poured out and tho apparatus Is ready
for another cow.
