service in the army he became surveying en-
gineer of northern Sweden In 1925 he con-
structed a condensing flame engine of ten
horse power, and in 1926 went to England to
introduce it. Coal, however, did not effect
the same results as pine wood, and the inven-
ton there did not succeed
In 1927 Erlcss n resigned from the Swedish
army, went TO England, and devoted himself
/ to the invention of various devices TO be used
at sea- In 1928 he made the application, in
the steamship Victory, of the principle of
condensing steam and returning the water to
the boiler He also invented self acting gun
lock for dischargiRg cannon at any elevation.
Not being able to agree with the British gov
ernment he kept his secret until 1913, when he
applied it to the wrought iron gun of the
Princeton. In 1929 he produced the steam
carriage Novelty and beat Stephenson's
Rocket in the trial contest. The locomotive
of the present day embraces some of his prin-
ciples.
In 1855 he invented the caloric engine,
which excited the wonder of the whole scien-
tific world, and resulted, twenty years later
in the completion of the caioric ship Ericsson
Over 6000 caloric engines have since been
constructed under his direction, many for
pumping water in private dwellings. For
this invention he received the gold and silver
Rumford medals from the American Acad-
emy of Arts and Sciences. In 1886 he in
vented the screw propeller, and in 1887 built
vessel with twin screw propellers. The
English did not place much faith in the
scheme, and it was not adopted.
In 1859, at the urgent instance Of Commo-
dore Stockton, United States navy, Ericsson
came tothe United StStes, and applied his
screw propeller principlc to tbs warship
Princeton in 1871. This Win other inven-
tions applied to war material and machinery
began the revolution of the navies of the
world. ELlcsson's engines were also applied
to the maritime marine. 4.
AT the worlds fair in London, in 1851, Err
lesson obtained the prize medal of the exhi-
ton for his numerous inventions. In 1854
he submitted to Emperor Napoleon III a plan
for submerged turret vessels, but it was not
adopted by him. 1t was, however, perfected
during the civil war, as recorded above, and
with great results, and in 1869 he built feet
of thirty vessels for the Spanish government
for the projection of Cuba In 1851 he de-
vised the Destroyer, with sixteen inch gun
protesting q missile. weighing 1,500 pounds
against the lisill of an ironclad beneath the
water line In 1888 he epflstructed his 'ssun
motor as a contribution to science intended
t6 develop the sup3yof mechanical energy
stored up.in the SUM-
The sun motor has not yet been completed,
but full directions have been left with his en-
gineers for the completion, with sufficient
SUN Of money TO carry it out under the direc-
tion of the executors. He also contributed
many scientific artieles TO various magazines
Besides the honors conferred upon John
Ericsson by Sweden he has been made a
knight of the royal orders Of Denmark and
