Machines

overcut, centercut, bottomcut, center
and slabshear, at any point between
the roof and floor of the coal seam.
Cuts up to IT, per minute.
Jeffrey L400 Loading Machine =
Loads up to tons per minute; finger
touch control
These cutters and leaders, control
led by one man, can do the work of
an entire mine face crew, in fraction
of the time. At the 1886 American
Mining Congress in Cincinnati, it was
declared that these machines are be-
ing installed more rapidly today than
ever before.
Electric Powered Conveyor Belts
u. S. Matchless-10-ply rubber con-
veyor belt; length, 1855 it.; weight,
Is tons; handles 10000 tons of ore
daily. Installed in Arizona copper
mine. (Anaconda Copper Coz
These belts are applicable in ham
ding any kind of ore and dirt, elm
mating the need of wheelbarrows,
mine cars, and trucks. Entirely auto
matte.
On the Grand Coulee project such
belts have already carried 100000
Gu. #. of excavation from dam-site to
dump nearly a mile away and 400
it. above the river.
Electric Textile Spinning
For details, consult the advertising
pages of textile industry journals,
such as Textile World.
Frames, Wrappers, carding machines;
dryers; opening-sewing and rerolling
machines; racking machines; count
ing machines; gigs; nappers; linters;
presses; brushes; spoilers; shippers;
weighers; slubbers; box hoists con-
veyors; hosiery finishers, etc.
The trend in this equipment is to-
word the fully automatic machine.
One rayon mill in New Jersey is now
operating entirely without man labor.
Electric Packaging Equipment
American Cyanamid Co.-three-tube
packaging machine, using one opera
tor, packs and weighs 700 to 900 sacks
of cement per hour. Each sack con-
tains "a lbs.
BY former methods, 2 men could
pack 500 bags per day. Now one
man packs 900 bags per hour. Over
$50, 100000 bags were packed in 1885.
Electric Lumber Plant
Alberni Sawmill-Vancouve Island,
B. c., plant uses 100 electric motors
and cuts 100000 board feet per shift
of 400 men.
This one plant can cut 150,000,00O
board feet of lumber per year with
only 1000 men.
PhotoeIectric Industrial Equipment
Toledo Printweight = photo-electric
controlled scales performs a complete
weighing operation every Is seconds.
In one plant, this machine auto
matically receives, weighs, records
and discharges 75O-lb. loads 80 tons
per hour.
V. S. Richman Lathe-on this. lathe
the shaping tools are controlled by a
photocell, which follows paper pat
tern.
Photoelectric counters, flaw detec-
tors, lighting regulators, conveyor
guides, safety devices, fire alarms,
burglar alarms, color sorters, speed
regulators, photographers, grading
machines, remote controls, etc.
These machines do lathe work en-
tirely automatically, displacing skilled
machine workers.
This equipment, in practically every
application, either directly displaces
abor or indirectly displaces it by
