the dairy work of the world and made
millions of dollars for those who have

richest men in Sweden. His good fortune

full of buoyancy and spirit. as fond of

with his associates. without a particle of
pretense or affectation. His work in the

5000 POUNDS TO THE INCH
But he has just perfected an invention
shown for the first time on the grounds
of the exposition now in progress in this
city, which bids fair to be known as the
most important one he has vet given to
the world It is a steam boiler of enor-
nous high pressure character. The boiler
works at the tremendous pressure Of 5000
pounds TO the square inch, a pressure I'M
known before in engineering. Perfect
safety. too is assured. and the danger di-
mipishes as the pressure increases IN
stead of large open boiler or one of
. large tubes, this new invention has in the
average boiler over quarter of mile of
solid-drawn, wrought iron tubing through
which the steam pasSeS-about 1.500 feet
! in all. To the engineer accustomed to a
pressure of 300 pounds 10 the square inch
as the maximum of his boilers, a pressure
of 1000 pounds to the square inch seems
quite beyond the range of possibilities,
Yet this Swedish inventor has demon
strated that 5000 pounds pressure may be
sustained without the slightest danger of
explosion.
The boiler is. in reality. single tube.
less than an inch in diameter. into which
the water is pumped escaping as steam
at 4 nozzle at the end of its quarter of a
mile journey. 1t then strikes the steam
turbine wheel. which in turn drives the
machinery. The steam has not entered
any large chambers of any kind. It is eX-
planned from a scientific standpoint that
the higher the steam pressure the smaller
! IS the specific volume of the steam, and
{ consequently, the diameter of the tube
may he kept smaller without any too
T great loss in pressure resulting from the
great velocity. In case the tube should
burst and; as matter of fact, the boiler
has been hurst on purpose by increasing
the pressure beyond the 5000 pounds per
square inch-the only result would be that
the steam would ESCAPE from the vent
made until the tube was all exhausted,
EXPLOSIONS ELIMINATED
SO it would seem the time is not far dis
tant when those who travel by land or
sea, those who live in great office build
ings-those, in fact, who are alaced at
any time in danger of explosions from

cause.
The tubing of the boiler is constructed
of solid drawn wrought iron wound in
concentric sDlrals 1t has been subjected
TO a hydraulic pressure of 6,000 pounds 10

might be subjected while in actual use
Many times the boilers in process of
testing have been allowed to explode in
the factory. and in an cases the excess
steam merely escaped through the tubing
