The semi-automatic electrical punch.
ing machine. which will be used. Is
built on the plan of a typewriter. with
a keyboard very similar in appear
ance. but having 240 different keys.
The machine, In its operation, differs
from a typewriter In a most important
respect. AS Is well known in operat.
ing the typewriter, every time key
is depressed. letter is printed and IL
mistake Is made, the letter must be
crossed out or corrected. with consid-
cradle loss of time and disfguring Of

chine obviates this as the operator.
instead of punching one hole at n
time. can depress into position for
srtsequent punching as many keys
as are necessary to record the re-
quired facts. Each key is independ.
cnt of all the others and can be re.

or discovery of the key in error. In
the old style punching machine, hole
was punched in a card every time the
plunger was depressed. II an error
in punching symbol was made, the
card had to be taken out and thrown
away. AS the punchers efficiency was
based largely upon the number of
cards punched in day, 1t will be seen
that the old method laid the operator
open to the temptation to let the er.
ror stand.
with the old machine, a sKlllful
clerk could average 5000 cards a day
Another time and money-saving fea.
ture of the new machine is that the
feeding OF cards to the punching keys
is entirely automatic. As the blank
cards are fed in from the rear of the
machine, the punched cards are drop
ped into a magazine in front.
While the operator is punching a
card the machine also by means OF
"A "glng.punch," is automatically ap-
plying a mark, or designation, to the
card which shows that 1t is one OF
the total number representing all OF
the population in a particular census
area, whether city, county or state
Automatic counters are attached TO
the keys and ip this way preliminary
announcements of certain important
population totals may be made as soon
as all of the cards have been punched.
Under the old system, when all the
punching was done by hand, those fig.
ures we're not available until the tabu-
lating work was started,
Tho census bureau has ordered 5000
of these new punching machines, and
II is calculated that the facts ON the
population schedules can be trans.
ferred to cards by a double shift OF
employees at the rate of about 25,0OO,.
600 cards month
After the cards have been punched
and verified, they are ready for the
new semi-automatic electrical tabulat-
ing machine, similar in many respects
to the one used in the twelfth census,
which was invented by Mr.. Hermann
Honerith. 1t is in the form of a heavy
cabinet, from the front of which ex.
tends movable arm or lever attach.

"pin-boX." containing n pin for each
possible hole in a card.
