4 / WONDERFUL INVENTION:

and the result Of his labors, should its
practical and permanent success be equal |
to its present promise, must certainly be |
regarded Is one of the most wonderful
achievements Of the age. The CORES
pondent Of the Leader has seen this: en-
CINE in operation. 1t is propelled by q
heretofore unknown vapor Of immense
pressure, created from small quantity
Of water, with certain admixture. Of
air. This vapor is purely produced by
Gals whatever, without the aid Of galvan.
ism or electricity, without heat, and
without cost, aside from wear of ma.
chinery and expense of an engineer.
Mr.. Keely has for years been i'nbuei
with the belief that motor was hidden
somewhere which could be utilized in the
place OF steam, with comparatively little
cost. He started out by endeavaring to
use the pressure of atmosphere as = mo-
tor, and his first construction to that end
was an air engine which proved entirely
satisfactory. The piston-rod of this en-
CINE WAS fastened by circular metal
plate to an 1ndia-rubber diaphragm on
the top of the cylinder. By some mys.
FERROUS arrangement the air is exhausted,
and : vacuum formed which compels the
diaphragm to bulge inward several inches.
When the air is let in the diaphragm
bulges outward, in that way working
backward and forward several hundred
times minute, making that number of
revolutions in the engine. How he man
aged to make fifteen-pound pressure of
the atmosphere do more than overcome
an opposing equal pressure of the same
atmosphere is mystery. He did it,
however, without the aid of electricity,
galvanism, or heat, simply with the as.
sistance of minute quantity Of water.
The engine seems to have been propelled
somewhat on the principle of an
hydraulic ram, aud Mr.. Keely sue.
ceeded in making it work purely
by atmospheric pressure, without
electrical Or chemical aid, or without
heat. The models Of this air engine oc.
cupied = space less than cubic foot, and
made 800 revolutions minute with such
force that the strongest man, with his
hands encased in pair of gloves, could
MT stop it by holding on to the fly wheel.
Tho objection to this engine as it was
then constructed Was the necessity for
using an india rubber diaphragm, whica
would make it impracticable for large
engines. While experimenting upon and
endeavoring to do away with the use Of
the diaphragm, Mr.. Keely accidentally
discovered another motor-a new and
heretofore unknown vapor. He saw that
this vapor could be compressed and made
to give almost IN unlimited amount of
pressure, and that it could be made to
propel an engine precisely As steam en-.
CINE is propelled.
Mr.. Keely then set to work to construct
= mechanical apparatus to produce this
vapor, and, after vast amount Of ex-
perimenting, has succeeded almost beyond
his expectations. The apparatus is cal.
led generator" or ':multiplicator." It
is about three feet high, two feet long,
and thirteen inches deep, made Of glass
and wrought iron in heavy and strong
manner, the whole of which con.
sists Of series of iron chambers,
cylindrical in form. connected by pipes fur
nished with various cocks and valves.
The multiplication was suspended from
the ceiling by. = chain. three feet above
the floor. showing it to be entirely discon.
nected with anything else, excepting the
pipe connecting it with the "receiver.''
The vapor generated is conveyed to the
receiver, and from the receiver it is con-
veyed by = ''feed pipe to the engine.
The receiver is made out of wrought iron
two inches thick; capacity about twenty
gallons and shaped like o soda fountain.
The popularity Of this receiver is, it is
made of wrought iron, without q rivet,
and entirely welded. The question is,
how could . receiver, shaped like soda
fountain, be made Of wrought iron, en-.
tirely welded without an anvil inside and
without rivet?
The popularity of this vapor is that it
can only be used to the best advantage
at pressure OF 10000 to 10000 pounds
to the square inch! The most extraord-
mary thing is that Mr.. Kelly is enabled
to control his vapor at that immense
pressure, and run his engine With pre.
cisely the same ease at which the ordinary
steam engine is run.
It is well known that the weakest point
in boiler is where il is rivited. If
boiler could be made entirely Of welded
iron without rivets, it would be one.third
stronger. The smaller the boiler the

inches in diameter will stand twice the
pressure that boiler forty. EIGHT inches
in diameter can of the same thickness Of
iron, or three times tho pressure that
boiler seventy-two inches in diameter
can. Consequently, ! receiver" of only
about fourteen inches in diameter must
De 50 much stronger in proportion than
the large sized boiler. The receiver
preserves IN equal temperature, and is not
exposed to any Of the difficulties that the
steam boiler is-it being constantly
filled with cool, dry and clean vapor.
This alone gives the receiver at least
more than double the strength Of the
boiler, everything being equal. The
bursting Of cannon is caused by the in
tense heat Of tho burned powder. OK pand.

Mr.. Keeley's principal difficulty lay in
making the metal sufficiently tight to
prevent this thin vapor being forced
through by that immense pressure. He
overcame this BY planishing the receiver
on the outside, shutting up the pores, and
by putting certain chemicals with water
on the inside and corroding the metal,
thus closing the pores inside with oxide.
In order to reduce that immense pres.
