manufacturers of adding machines
have recently extended the scope OF
their business by building enormous
plants. almost doubling the force oil
workmen employed in their respective
concerns, and greatly increasing the
equipment. Capital. running into mill
ions OF dollars. has been willingly SUB
scribed by investors. confident of the
future and assured OF the success OF
these giant ventures. Sales forces
have been increased--in many cases
almost doubled-due TO the demand
Tor machines with which mechanical
brains solve problems and do the
drudgery which was once the terror OF
the office worker
And il is said. and with apparent
truth. that the development OF me
adding machine industry is still IN Us
infancy. Each day sees the discard
ing OF some mechanical feature aLu
its supplanting BY something better,
newer. more productive As IN the
case OF the typewriter, the earlier
model machines with their deIects-
a natural result OF the inexperience ot
the first inventors and patentees art
being superseded by improved So L.
machines, as far superior in their con
struction and accomplishments as Was
the first automobile TO the one-hoIse
shay OF historic memory. Truly the
world do move as the ancient darby
said
Experience and time is the sure
test OF any invention Irrespective OF
the brightest dreams OF the inventor
IL is the test OF the busy othce, the
strain. the hammering, the nara
knocks TO which machine is SUB
iected while in active service that de-
termine its fitness for all around ser
vice in the busy counting room or
office No chain is stronger than It's
weakest link runs the proverb, and
when that link gives away the chain
is worse than useless. likewise an
adding machine or typewriter tdal
has weak links may last for months
perhaps years-but il will eyentua-
ly fail. and perhaps at time or on an
occasion when Il can least be spared
So the elimination OF the weak links
in the modern computing device is The
aim OF the modern inventor.
There is a new arrival in the field
OF adding machines. remarkable de-
vice with exclusive features that com
mend IL at once 10 the attention or the
business concern interested in secur'
ing a machine with all the improve
ments and none OF the defects OF
other adding and computing machines
now on the market the only adding
and listing machine ever produced
whose addition does not depend upon
springs. gravity or friction. Every
part OF its adding mechanism Is driven
into position by cam gear and lever.
It's operation is as positive as gear
drive. Ii one paQ Of the adding
mechanism moves, all the rest must
move; II one part is blocked. all the
parts are blocked. Ii is the only ma
chine which embodies these features.
This machine belongs TO a type
known as the full-keyboard listing and
adding machine, which accommodates
both roll and wide paper. The term
"full' keyboard Is used 10 distinguish
il from the type OF machines known
as the nine-key machines.
The usefulness OF the machine is
greatly increased by the provision
having been made for two sets OF &C
cumulators. one for the debit column.
and the other for the credit or any
other classification desired. BY NOV
ing the carriage from one column 10
another the proper set OF accumula-
tors is thrown into direct line OF sight
OF the operator and the amounts set
up on the keyboard are added TO the
accumulators which are in sight.
When IL is desired 10 add on the other
set OF accumulators, IL is simply nee
essary TO shift the carriage 10 the
other column and the other accum Va
tors will come into sight and the
amounts will be added to them. When
the total or sub-total is taken the
amount will be the same as that which
is shown on the accumulation wheels
which are in sight All keys and lev
ers are operated by the right haLd,
leaving the left free for keeping track
OF work or turning checks.
The keyboard Is made low enough
SO that the operator may be seated
comfortably in front OF the machine
and operate il with ease. Carbon
copies are produced by simply laying
the manifold ON the large platen anG
pulling a paper clip over each end.
BY this means IL is not squeezed in
between rolls, and the carbon copy is
not smutted.
A remarkable and commendable fea-
turc OF the machine is that with niue
banks and two accumulatoTs only
| SCI parts are used as compared with
almost double this number used In
certain other types OF adding ma
chimes. On account of the simplicity
of design OF this machine, IL has been
found possible to make parts OF larger
and more substantial construction and
the inventor has been enabled to get
down TO real machine construction.
insures also the durability OF the ma
chine 1t will perform accurate work
with little alteration for a lifetime.
A very convenient feature OF the
new machine is the method by which
paper Is inserted. To insert the paper
il is simply necessary TO place II on
the platen and pull one OF the paper
clips over each end. These clips will
hold the paper in place firmly in the
same manner as the fingers hold
paper on cylinder printing press.
Roll paper may also be inserted In the
machine in a manner more convenient
than In certain other machines, be-
cause the roll is mounted on the car
riage and may be shifted TO allow for
