The tremendous strides made in tho
adding machine industry are being
daily attested by the almost unprece-
denied sales or computing and adding
machines In this country. Business
men, alive as never before TO the great
economy and time-saving features OF
the modern adding machine have
come to regard 1t as one or the nrst
essentials In the equipment OF an
Office; indeed there Is hardly a busl-
ness concern In the country today that
| lays claim 10 progressive methods In
whose Offices a machine OF this class.
made by one or the other manufactur
ers of standard machines, Is not found.
The adding machine Is no longer a
luxury; IL has been found to be one
of the real economies OF the office,
saving a vast amount or time, labor
and worry, and cutting down ONCE
expenses 70 figure that makes II In
dispensable to the concern desiring to

AS an indication of the gigantic
business which has been developed as
result of the demand for modern
adding machines may be noted the
fact that two of the representative
manufacturers OF adding machines
have recently extended the scope OF
their business by building enormous
plants, almost doubling the force or
workmen employed In their respective
concerns, and greatly increasing the
equipment. Capital, running into mill
ions OF dollars, has been willingly SUD-
scribed by investors, confident or 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
for machines with which mechanical
brains solve problems and do the
drudgery which was once the terror OF
the Office worker.
And 1t is said, and with apparent
truth, that the development OF the
adding machine industry Is still In It's
infancy. Each day sees the discard
ing of some mechanical feature aid
its supplanting by something bette',
newer, more productive. AS In the
case Of the typewriter, the earlier
model machines with their defects
natural result OF the inexperience NJ
the first inventors and patentees-are
being superseded by improved style
machines, as far superior in their con.
struction and accomplishments as was
the first automobile to the one-horse
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 Office, the
strain, the hammering, the hard
knocks to which a machine Is sub
Jected while In active service that de-
termine its fitness for all around SER
vice In the busy oounting-room or
Office mo chain is stronger than Its
weakest link" runs the proverb, and
when that link gives away the chain
is worse than useless; likewise an
adding machine or a typewriter tiat
has weak links" may last for months
perhaps years-but II will eventual
ly fail, and perhaps at time or on an
occasion when 1t 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 new arrival In the field
of adding machines, remarkable de-
vice with exclusive features that COM
mend II at once 10 the attention OF 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 it's adding mechanism is driven
into position by cam gear and lever.
Its operation is as positive as a gear
drive. If one part OF the adding
mechanism moves, all the rest must
move; If one part Is blocked, all the
parts are blocked. 1t is the only ma
chine which embodies these features.
This machine belongs 10 a type
known as the full-keyboard listing and
adding machine, which accommodates
both roll and wide paper. The term
full keyboard Is used to distinguish
1t from the type of machines known
as the mickey machines
The usefulness of the machine is
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
