MILKING MACHINE.
Another Invention to Save Hand Labor on
the Farm.

Here are an illustration and descrip-
ton of the milking machine now in use
in the dairy department of Hiram G.
Wheeler's farm in Iowa. They are cop
led from the Chicago Times-Herald:
No. 1 represents collapsible vacuum
storage chamber, fastened by the top
and inside of the frame, which is shown.
No. 2 represents box, which will con-
tain about l 200 pounds of sand or dirt,
which is so made that it will slide up
and down inside the frame, and is suit
ably fastened to the lower end of the
vacuum storage chamber (No. ~. No.
represents a metallic air pipe or tube
leading from the top end of the vacuum
storage chamber mo u to the air pump
(No. A.. The air pump mo. A. is suit
ably provided with check valves, one
being an inlet and the other an outlet
Attached to the main pipe mo 81 is the
vacuum gauge (No. 81. No. 6 repre-
sents branch nipple fastened to the
main air pipe (No. 81. No. represents
a rubber air hose, one end of which is
attached to No. 6 and the other end to
the air valve (No. 81. The valve (No
81 has nipple which extends through
the cover of the end milk can The or
binary eight and ten gallon milk cans
are used for the milk receptacles, and
enough of these cans are always used
with the machine to contain the milk of
all the cows to be MIXED, so that the
vacuum can be created in all the cans at
one time and before the milking is start
ed. No. represents the tubes attached
to the milk can covers and the rubber
tubes connecting the several cans.
1t will be noticed that the end milk
can has an L shaped tube and that the
next can has T shaped tube. All Of
the shaped tubes extend through the
cover down into the can about five
inches. The can nearest to the main
milk conducting pipe (1O) is connected
by suitable rubber tube to it. The main
milk conducting pipe (10) is fastened
along the stanchiOns as near the ground
as practicable, the end nearest the milk
cans being lower than the opposite end.
No. IL represents special rubber milk
tubes which branch from the main milk
conducting pipe to a point in front of
the cows fore feet, but little to the
right, so as not to interfere with the
cows lying down in the stanchions
One of these tubes CD branches from
the main pipe for each COW in the herd
Attached to the other end of the branch
tubes (11) are the compound tees and
teat cups.
The manner of using and operating is
as follows: The cows being in their
proper stanchiOns, the operator works
the air pump az by hand, drawing the
air out of the vacuum storage chamber
until it is practically fully collapsed
and has drawn the weight box up as far
as possible. The operator then puts the
milk cans into their proper places. The
covers, each one of which has a small
rubber ring around it, are put on the
cans and pressed down so that with the
help of the rubber ring an alright con-
nection is made with the cans. The
valve (S) is then opened. There being
vacuum in the vacuum storage chamber
and air pump 81, it is apparent that
the air in the milk receptacles and
branch tubes will be Immediately drawn
into the vacuum storage chamber and
that the weight (2) will descend. The
operator can then pump out all the air
that has been drawn into the vacuum
storage chamber, and the machine is
ready for the milking. The operator
takes a set of teat cups with compound
tee and branch tube, from the hook and
successfully applies them to the ami
malls teats and opens the valves in the
compound tee belonging to them, where
upon the teats are instantly drawn into
cups by suction. The operator then goes
to the next animal and repeats the oper-
alton. The milk flows from the teat
cups through the branch tubes into the
main milk conducting pipe and thus
into the milk cans As soon as the milk
rises in the first can so that it covers
and seals the mouth of the 7 shaped
tube referred to, that projects down into
the can, it will be apparent that the
suction will be arrested for that partic-
ular can, and hence no more milk will
enter it. The milk will simply enter
the tube until it runs over into the next
can, and so ON.
The vacuum storage chamber when
fully collapsed will milk from 10 to 10
cows before it is necessary to pump the
air out of it again, the number of COWS
depending ON the quantity of milk they
give. AT any time during the milking
operation the operator can step to the
pump and pump out part or all of the
air III the vacuum storage chamber.
When large number Of cOws-as, for
instance, 100-are attached to the ma
chine at one time, it would be necessary
to have some one at the pump nearly all
the time.
The mixer has been found to be q
great labor saving machine, as with it
one man can milk from % to 90 cows
per hour, the average speed of the aver
Age man with an average lot of cows,
1nder ordinary conditions, being about
30 cows per hour.
