The Western news. [volume] (Libby, Mont.) 1933-current, 1934-12-27

Attached to the mast are two double
and one single blocks; a third double
drum block is attached to the track
cable. Through the double blocks is
threaded a ri inch tension cable, one
end of which is spoiled on one drum Of
the hoist the other attached to a la
inch track cable. BY means of the ten
sion cable, me track cable may be
lowered or frightened at the will of the
hoist operator.
Mounted ON the track cable is three
wheel carriage weighing about 800 lbs.
From this carriage is suspended 5000
lb. one-yard Sauerman buckets equip
ped with bride or haul in and dumping
chains This is a standard Sauerman
Bros. set up.
When the bucket is at digging point
the tension cable is Stacked, the track
cable is lowered, the carriage and chain
aggregating about 1000 lbs. drops on top
of the bucket giving the latter addi-
tional weight during the digging pro-
cess. Attached to the bride chains of
the bucket is a one inch cable This
cable is run through the single block
on the mast and spoiled to the other
drum of the hoist
By means of this cable, the bucket
is pulled forward until it is loaded The
track cable is made taut by a couple
of turns Of drum the bucket is then
/ suspended in the air and is by means
/ Of the load cable, described, brought
to the dumping point at comparatively
high speed with minimum Of friction
or other resistance, returning by gravity
to loading point A part Of the bucket
assembly consists of specially made
dump block. AT dumping point, this
block comes in contact with stee
button attached to the track cable. The
effect of this contact is to slacken The
bride chains and other bucket assembly
and trip the bucket, dumping its loac
onto the grizzly.
Grizzly, Bin and Feeder.
The grizzly is inclined sufficient,
to permit all oversize boulders to rol
Of to one side9where they are perman
emily out of the way The grizzly bar
are heavy steel rails laid bottom side VI
and spaced II inches
The minus material drops into a stee
lined bin of capacity of about fly
cubic yards. The bin anl. grizzly ar
both elevated the lower side or dis
charge end of the latter being abou
% feet above the surface Of tn
ground The material in the bin feed
automatically and by gravity to tn
washing plant without the aid G
special feeder.
Washing Plant.
The washing plant consists of fiv
inch centrifugal pump, revolving scree
and sluice The sluice is 3x3 feet lai

! equipped with 2x6 inch rifles lai
vertically and transversely>.and space
2 inches. On each wooden rifle IS lai
! a 80 lib. steel rail 3 feet long The raj
are locked together with wooden lug
This sluice and its qualities as a con
!, centrating plant were described in a

As above suggested, the minus stu
