The Rival Feeders.

Mr.. EDITOR: L nOtlc6O IN your ISSUE
of the 9th inst. letter from Mr.. w. II.
CornweI, OF Waikapu plantation, Maui,
as a testimonial anent the workmanship
and performance of a Risdon Iron Works
two roller mill. With that l have no
fault to find; but I cannot allow the
answers to inquiries on same to pass I'M
noticed.
The hexagonal roller spoken OF for
feeding the trash into the two roller mill,
at Waikapu (said to be the smallest
maceration mill in the kingdOm), is the
same continuance that was used on the
largest diameter two roller mill in the
kingdom, by the same makers. Now it
is quite true that the contrivance men
toned will feed two roller mill, if there
is not too much pressure on the upper
roller, and the crushing in three roller
mill is not too we'll done it is also no
doubt true, that mills OF that make have
the qualification of d" groaning" and
d" trembling" when there is more trash
than they can put through. This is
convenient, for it is understood to be a
" warning" for the attendant to pull OF
the surplus trash from the carrier.
The nOint sought to be made by both
the letter and answers to inquiries is, to
show that a common Stat carrier with
this hexagonal roller does just as we'll as
the automatic trash FEEDER patented
by me in 1885, and of which the Honolulu
Iron Works Company have already made
and applied SO, with the most satisfac-
tory results; two more are being built.
As an offset to answer to inquiries referred
to above, let me state that the RisdOn
Iron Works in 1885 built 40 diameter
two roller mill, with the same kind OF
slat carrier trash feeder, for the kOlOa
plantation; this was, and is now the larg-
est diameter two-rOller mill in the king
dom. The Koloa Plantation Company
ran said mill for a whole season, during
which time quantities OF cane were
weighed off more than once, under the
supervision of Mr.. Williams, who repre-
scented the makers of the Risdon Iron
Works MILL and taken from the same
pile of cane at the mill, for competition
tests, between one of the Honolulu Iron
Works Co.'s 30in. Coin. two roller
mills, fitted with my feeder and work
ing behind a Pain. x 4Sin. three roller
mill at the Hanamaulu plantation, twelve
miles distant from the KOloa mill. The
KOloa three roller mill was 26in. 54in.
regular Honolulu Iron Works make
and the above mentioned 4Oin. K. l. w.
two roller maceratiOn mill behind it.
Everything, as will be seen from dimen-
sions, was in favor of the KolOa mills,
except the method of feeding; and to
that one thing-the patent automatic
feeder-was due the showing of about
per cent. in favor of the H. l. w. two
roller mill, even with the small three
roller mill, from which it took the trash.
My information is from Mr.. E. Kopke,
who together with Mr.. Williams super
intended all the tests; and than whom a
more qualified and experienced planta-
ton engineer is not in the Kingdom. 1t
should also be mentioned, that the Koloa
Sugar Co, after having had sufficient
trial Of the slat carrier with heXagonal
roller and running through a whole sea-
son, called upon me to put on my auto
matte feeder, for which they paid the H.
I. w. Co. $977.78, and to me, personally,
$4,000 royalty besides. Close mill man
ayers don't do such things without due
consideration, and certainty of advan-
tage. The manager of KOloa plantation,
after having started up with the auto
matte feeder, writes to me as follows:
DEAR SIR: | take great pleasure in
informing you that, after having put on
your automatic feeder on our maceratiOn
mill, the mill gives great satisfaction"
The reason the two roller mills "grOan"
and "tremble'' SO frequently, and reject |
the feed, is because of the irregularity |
with which they manage to get hold of |
the trash. At Spreckelsville, where the |
same kind of carrier between the mills is |
used, they relieve the hydraulic pressure |
on top roller, and let the trash through, |
when ''grOaning" and trembling" COM
this is better than raking the
surplus trash off the carrier.
Without taking too much of your valu-
able space, ! would ask to be allowed to
say further, that two roller mills of any
size, fitted with my automatic feeder,
will take their feed steadily from morn
ing till night, doing the same quality of
work throughout, making no difference
how great the pressure on the rollers.
and needing no attendant to regulate the
trash; and this cannot be done with any
other method of feeding in existence, and
for the class of work sought to be done
in these days, no mill should be without
. oung's patent automatic FEEDER for
twO-roller trash mills.
| would also beg to state that the said
Waikapu maceratiOn mill is not the |
smallest in the kingdom, for the macera-
ton mill at Hilea, Hawaii, being only
% gin. 40 12in. rollers, is the smallest. |
which is fitted with the " automatic |
feeder" Young's patent; and according
to the Managers report does as good |
work as the 30in. Coin. at Honuapo. |
Besides, with the two now being built.
there will also be four maceration mills
26in. x 54in OF our make with YOuno's
feeder, in the kingdom.
