II is in planning machinery for man
ufactures that the inventor performs
one OF his most signal services. To de-
wise a huge hydraulic forge able TO
exert a pressure OF $4,000 tons, on the
one hand; and to make machine
which will cut thread with 200 turns
to the inch on the other, represents
wide range of ingenuity, and the III
yentor has been able TO do both. One
machine will produce giant cable;
while another will make a wire only
one-tenth the diameter OF womans
hair. Another machine will weave an
iron netting heavy enough for the
front OF a Tigers cage; while another
will produce u steel gauze 80 finely
spun that It has 10000 meshes TO the
square inch. The manufacturer Is
able TO make a cutting machine which
will cut slices OF material so thin that
thousands may be piled up IN layer
an inch high: and on the other hand
1875 tons and cut a groove through
steel with IA much ease as knife
cuts a slice OF bread.
a large proportion OF the laoor'sav'
ing machinery OF the world has been
produced by the American inventor.
Labor in this country always has re-
ceived better rewards than In other
countries and this has made the neces-
sity OF laborsaving machinery all the
greater. The result has been a great
stimulation in the EFFORT TO solve the
problems OF mechanical production.
One OF the first labor-savers invented
in the United States was a machine
for making nails. II was the inVen-
ton OF Ezekiel Reed. OF Bridgewater,
Mass. The nailmaking machinery OF
the world has undergone many I'M
provements since the day OF Reed. and
nails are produced so cheaply now
that. like a pin, II is cheaper TO pass
one by than TO stoop and pick 1t up.

American ingenuity, so also Is inc

The possibility of carpets TOT the
millions was brought about Dy an Ia
vention of Erastus Bigelow. OF BOSTON,
who. In 1914, brought out power
loom for the weaving or ingram car

making are the result OF patents ls

ventors. These enable few operators

than a hundred could on one OF the
old-time rope-walks OF Kentucky.
he Hoe printing press is only one
step forward in the application OF me-
chanical knowledge, and yet mod
ern newspaper press, operated by five
men, will produce more papers In an
hour than a pressman and his assist
ant could turn out in hundred days,
working ten hours a day, with an old
| fashioned Franklin press. IL the
world obtained it's newspapers as II
did a hundred years ago, the daily pa
per OF the present would have TO be a
/ quarterly, provided the demand for pa
pers was as great. The new printing
press has made IL possible for the
smallest state in the union to produce
hundred times as many papers as
were turned out in the whole country
| hundred years ago.
The modern elevator. which has
made the tall buildings OF the world
posslble. and therefore. modern city
conditions. was invented by an Ameri-
can. The first ideas in safety devices
! for elevators were In the shape OF air
tight chambers at the bottom or the
SHAFT. II was figured that II the ele-
yator should fail, 1t would strike on n
cushion Of imprisoned air, thus render
ing the danger practically nil This
| idea was followed for a long time, and
/ I'm the course of experiments, 1t was
discovered that with properly con
structed shaft, an elevator could fall
! 2S7 feet without fracturing an electric
light bulb or breaking an egg shell.
since then the safety clutch has been
placed on the elevator and the air
! tight chamber 1T the bottom OF the
shaft has almost disappeared.
An American first conceived the
modern ice-making machine, and the
many blessings that have grown out of
artificial refrigeration had their begin
ming in the crude little plant con
