taneous. The transmitter has an arrange
ment of segments, each of which CORE
spends to certain key on the central
keyboard. The tickers also have revolv-
ing type wheels containing the same let
ters >and numerals. as those on the key
board. Perfect synchronism exists be-
tween the keyboard. the segments on the
transmitter and the type wheels of the
tickers.
When the keyboard operator presses a
certain key on the keyboard the trans
mitter, on reaching the segment CORE
spending to the key pressed, Immediately
stops and sends over the line the neces-
sary number of pulsations to make the
type wheel of the ticker revolve in unison
with it. The same action causes a platen
In the ticker to rise and press the tape
against the type wheel, with the result
that the proper character is instantly i'm
pressed upon the paper.
Any number Of circuits with tickers
are thus operated, causing all tapes to be
printed alike. The speed Of the ticker Is
just twice that of the Morse sender AS
an illustration: 'July wheat 1.25M" by
Morse telegraph requires twenty-eight
contacts on his keyboard. The printing
telegraph can reproduce on the tape just
double the number of quotations that the
fastest Morse telegrapher can send.
In addition to transmitting its quota
tions to every part of the country In the
manner described the Board Of Trade
also makes use of a special ticker SER
vice devoted to the dissemination Of
news, statistics and other valuable in
formation. This information is distrib-
uted over the so called Broad tape tick
err" an electrically operated instrument
keting Of grain and provisions. The
transmitter. of this device consists Of a
mechanism with keyboard like that Of
a typewriter and in operation works on
the same principle as the keyboard Of the
quotation ticker.
Genoa conferences" and similar news
events are of vital Importance to tho deal
ers in grains, almost as important as the
price quotations The news service sent
out by the Chicago Board Of Trade is
highly regarded for its condensed and
reliable character.
The tickers receiving this service,
which are located in practically all com.
mission houses and on the exchange floor,
are connected by wire to the transmitter
and print instantly on roll of tape about
six inches wide all news that Is trans
mitted by the operator. Market news and
quotations from all foreign countries as
we'll as domestic markets are gathered
and distributed over these tickers. The
trade watches the news tickers very
closely and is posted up to the minute on
ell important developments and general
price movements in the markets of the
world.
Among the features of this ticker SER
vice is the rapid broadcasting Of news
to small country towns throughout the
States by way of the private wire sys-
TENS. Many commission houses have
private wire systems reaching all parts
Of the country and they relay the news
from these tickers in their telegraph
Offices as fast as II is printed to their
branch offices. Thus news item OF i'm
portance is flashed throughout the coun
try within few minutes after its publi-
cation on the ticker tape. Small town
newspapers In many cases depend on the
branch offices Of the Chicago commission
houses for most Of their commercial news
The United States Bureau of Markets
also uses this ticker service for the dis
tribution of its live stock market reports
and recognizes the system as rapid and
inexpensive way of publishing its reports
almost simultaneously.
1t will be seen that the strenuous
traders Of "the Pit" play an important
part in keeping the world wide awake as
well as in feeding IL.
