| \ Telegraph plant connecting the IRE
houses is a part Of the system. when one
house learns OF a FIRE in any but the regu-
lar way the telegraph instrument is called
into reduisition and with few dots and
dashes all the other houses and the FIRE
operators are told Of the FIRE and its To-
cation.
one Recent Invention.
A late invention, and an important one,
too, IN the way OF fire protection, Is an
automatic system for buildings which indi-
Gates on which floor the fire Is located.
It is used by nearly all the largest whole
sale and retail houses Of the city. Among
the best equipped are the Bemis Omaha
Bag company and the McCord- Brady COM
pany Instruments sensitive to heat are
placed at various points on each floor and
are connected with dial in the once and
with a dial box on the outside Of the
( building. One wire runs to the American
District Telegraph Office, which gives tho
alarm to the FIRE department. When the
fremon arrive they read on the dial In
front of the building the number of the
floor on which the fire is located.
Electricity and The Bee.
| All the machinery used in printing The
Bee Is driven by electricity. complete
electric plant is maintained in The Bee
building, furnishing power and light TO the
newspaper rooms and other parts of the
building. The electricity is generated by
two direct converted multi-polar generators
one of s5-horse power and the other of 125-
horse power Formerly all the machinery
used in the production Of the newspaper
was operated by one motor. but last fall
an individual motor system was installed,
obviating the necessity OF turning all the
shafts when only one machine was in use,
and saving a great deal in the expenditure
| of power. Tho individual motor system
| means a motor for every machine, each
motor furnished with electricity by wires
| running from the generators. Twenty
eight motors are used in the building, four
| teen for linotypes and other machines in
| the composing room, seven in the stereo-
| tipping rooms, two in the press room, two
| in the mailing room, one for the pneumatic
tube which takes the copy from the edi-
/ torial rooms to the composing rooms, one
for a ventilating fan and one for a lathe.
The turn of a small lever will set any one
of these machines in motion.
All the appliances are made with a
view TO the saving Of time. They start
the machines quickly and stop fhem just
as quickly. When an operator in the stereo
tipping room starts machine, he does not
need to watch 1t. He turns to some other
work and the machine stops automatically
as soon as It has finished the task he has
given IT. At various points about the big
presses are levers which may be thrown
to stop them when anything any part of
the mechanism breaks. Besides instan-
taneously cutting off the current, it applies
an electric brake which stops the machine
almost Immediately.
The idea in having two generators Is
that one may be used in case the other
gets out of repair Sometimes the small
generator is large enough to furnish all the
power needed; at other times when the
work is heavier and especially when two
presses are at work getting out the Sun
day paper, both generators are required
At other times the small one is not quite
large enough and the large one is brought
into service. Enough power is developed
by the two machines for 2,1OO electric lights
of 16-candle power each. The large one
could keep 1900 lights going and the other
800.
Light is furnished to all the offices in the
building. Power is provided where it is
asked for and 1t is used by many of the
dentists and physicians. The dentists run
their drills with 1t from little motors in
their Offices and the physicians run their
X-ray machines with it. new machine
has been ordered for the mailing room
which will wrap and address papers with
lightning-like rapidity. 1t also is to be
operated by an electric motor.
Dental College and Electricity.
The new Creighton Dental school, which
is to be opened this fall is said by it's
faculty to be better equipped than any
other dental school in the world. Not bit
of work is to be done by any other power
where electricity can be used. Copper
wires come from the walls and ceiling at
several places in every room. Every drill
to be used on teeth in the mouth Of the
human subject. every piece OF apparatus
for g,in6. or polishing teeth or annealing
metal, will be operated by electricity.
One big room is fitted with several dozen
chairs where the students pull and fill
teeth. Before each chair is a little motor
connected with a wire coming out of the
WALL making the work Of the dentist the
most convenient. For annealing there are
electric furnaces on tables mounted on roll
lers and one OF these is pushed directly be-
hind the dentists chair, so that he has to
move but a single step in his work.
new electric device TO be placed in the
dental school is called the Kaleidoscope In
appearance It is much like a stereopticon
and 1t casts a picture on a screen just the
same. No slide is needed, but drawing or
a leaf of book can be put into the re-
nectoscope and reproduction of the fig
ures will be cast in magnifed form on a
screen. 1t reproduces colors. The labora-
tories will be fitted with motors and cleo
trio furnaces and ovens. Two rooms are
to be reserved for the use of the faculty
In their experiments and the electric fix
lures there will be a marvel to the one
only moderately versed in electricity.
Power for Grain Elevators.
The elevator of the Nebraska Iowa Grain
company 0nd that Of Merriam & Holmquist
are operated by electricity. The former is
good example Of the well equipped modern
elevator.
Cars are pulled along the track. the grain
is unloaded, cleaned and loaded by cleo
tricity, and all is done by three men with
less EFFORT than would be made by tan men
with machinery run by steam. At this els-
vator forty cars can be loaded and as many
unloaded each day. Five motors are used,
with an aggregate of LEO horsepower and
II the occasion requires, as much as 800
horsepower can be developed for two hours
at time. One motor is used for pulling
cars along the sidetrack, and It can handle
twelve cars at a time Two are required
to work the car shOvels for unloading grain
and the legs for hosting IT, One is for
