manufacturers OF adding machines
have recently extended the scope OF
their business By building enormous
plants, almost doubling the force OF
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 oi the
future and assured OF the success oil
these giant ventures. Sales FORCES
have been incTeased-7-in many cases
almost doubled-due TO the demand
for machines with which mechanlcal
brains solve problems and do the
drudgery which was once the terror oil
the office worker
And Il Is said, and with apparent
truth, that the development OF inc
adding machine industry IS still In It's
infancy. Each day sees the discard
ing OF some mechanical feature AID
its supplantlng by something better

other adding and computing machines
now on the market ths 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 IL as positive as gear
drive. II one pau OF the adding
mechanism moves. all the rest must
move; II one part Is blocked. all the
parts are blocked. IL 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 IL used 70 distingNeh
1t from the type OF machines known
as the nine-key machines.
The usefulness OF the machine fs
greatly increased by the provision
having been made for two sets Of ac-
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 to
another the proper set or accumular
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 TO add on the other
set OF accumulators. II Is simply nee
essary TO shift the carriage TO the
other column and the other accum Ia
tors will come into sight and the
amounts viii be added TO them. When
amount will be the same as that which
is shown on the accumulator wheels
which are In sight. All keys and lev
ers are operated by the right hand.
leaving the left free for keeping track
Of work or turning checks,
The keyboard Ii made low enough
30 that the operator may be seated
comfortably In front OF the machine
and operate II with ease. Carbon
copies are produced by simply laying
the manifold ON the large platen and
pulling q paper clip over each end.
BY this means II Is not squeezed IN
between rolls. and the carbon copy Is
not smutted.
A remarkable and commendRble fea-
ture Of the machine IL that with nine
banks and two accumulators only
,s61 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, It has been
found possible to make parts OF larger
and more substantial construction and
the inventor has been enabled to ger
down TO real machine construction.
insures also the durability OF the ma
chine. It will perform accurate work
with little alteration for q lifetime.
A very conYsnient feature Of the
new machine 10 the method By which
papsr is inserted. To insert the paper
Il is simply necessary TO place IL on
the piaten and pull one Of the paper
clips over each end. These clips will
hold the paper I'm place firmly. In the
same manner as the fingers hold
paper on q cylinder printing press.
Roll paper may also be inserted In the
machine In q 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
