A Machine at Iron
Works Which is
Accurate.
DESCRIPTION OF
VALUABLE PATENT
invention Of c. Hedemann Which,
Will be important in the
Sugar Business.

One of the most recent and valuabl.
production not only in the Hawaiian
Islands, but In all sugar-producine
countries. is the new cane-juice weigh
ing machine, being built by the Homo
lulu Iron Works, the patent for which
was taken out on February IS, Dol. by
c. Hedemann. manager of the iron
works. and now held by the latter COM
pany. There are two machines already
set up in the main shop of the works
where they have recently been exam
tned by sugar men. All who have ia
ken the pains to make a careful study
OF the automatic features of the ma
chine pronounce II one Of the most
important additions to the profitable
production of sugar, In that it gives an
accurate measurement of every drop
OF Juice that goes into the machine.
The smaller machine which Is now
being constructed by the iron works
has the appearance in miniature of the
walking beam mechanism of q side
wheel steamer. The mechanical weigh
ing features are so deIicately adjusted
that 1t takes but the weight of a drop
or cane juice to tip the weighing pan
over and allow the contents to run into
a tank. when it's holding capacity has
been reached, at the same time shut
ting or the flow until the opposite side
OF the pan Is presented for filling. BY
the same automatic process the flow is
again started. each tilt being automat-
ically registered. The machine now on
exhibition consists Of pipe lying hor-
fzontally across the top of the weigh
er. This supplies the juice into the
machine which is originally brought
from q tank and deposited directly into
the feed pipe. The juice will pass from
the feed pipe through a slit on the I'M
der side into a copper spout. This
spout discharges In turn into the So
called weighing box. made of copper, |
which Is partitioned In the center, the |
ends being open.
The weigher Is adjusted to tip one
side or the other by the reception of a |
certain amount Of juice. In the copper |
spout is knife-shaped blade, which, |
by an arrangement can be turned to |
the right and left, thus diverting the !
Juice into one partition of the weigh
ing box or the opposite side as the case
may be. When the Juice commences |
to en1 the feed pipe and Is discharged |
through the nozzle into the copper
spout, 1t will fill one side Of the weigh
ing box When the quantity of Juice
collected in that partition has reached
certain weight the weighing box will |
turn down, being mounted on knife
edges. and discharge the contents into
the tank below. from which 1t is taken
Tor further treatment into containers
made for the purpose.
By turning the Weighing box down,
the other partition of the weigher is
raised up and puts the partition in the
center OF the box in such a position
that the copper spout will discharge
into the new new side thus presented.
AS soon as the box commences to tilt
over. the knife-shaped cutoff plate
VIII make quick move. thus shutting
on the flow OF the juice into the parti-
ton which was filling. and turning the
Row over into the other end. The quick
movement Of this cutoff plate elimin-
ates all inaccuracies in weighing. The
arrangement of this cutoff is one of
the essential features OF the weighing
which have brought IL SO
prominently TO the attention of plant
ers
pipes which contain a certain guam
tlty OF mercury for the purpose OF
Keeping the weighing box in position
when filling, for such a time, that it
viii always take the full weight of it's
capacity before fitting. To avoid a
heavy jarring when the fitting occurs,
