INVENTION OF JOHN NJ. CAGE, DE.
SiGNER OF PROMISING
SUBMARINE VESSEL.

Denver.-Driven at an amazing
speed by 30-horsepower electric mo-
tor. two two-blaided propellers. revolv.
ing opposite directions inside steel
and canvas tube six feet in diameter
and eight feet in length, daily are dem
onstrating at the Mitchell machine
shop, 1925 Eighth street, that Denver
may soon be recognized by the world
OF aviators and aviation.
Daily, says the Denver Republican,
professors OF science In Colorado uni
versities, expert mechanics and com
mon-sensical business men gather in
the little loft of the machine shop. are
shown by John NJ. Cage, the youthful
inventor of the apparatus and the in.
ventor of the Cage submarine boat,
which Is creating more than passing
interest among the naval authorities OF
Washington and of the world, just
what his model can do, and leave the
shop with their cynicism gone, or. !"
not entirely dissipated, existing only
doubtfully.
Although only model designed to
show that the problem OF Harvesting
the air and making 1t lift weight for
man Is one which has been solved to
some extent, at least, the apparatus
has satisfied many of the experts in
aviation matters. Not an airship. not
even the model OF an airshp, the hell
copter.-for that is what II is. some
what improved in construction--repre-
sents only one-half the lifting power.
for the machine will have two of tho
flyers" designed for the airship plan.
ned by young Cage.
The method OF driving the air
through the tub is unique, also. the
first propellers grasping the air
just inside the tube opening and whirl-
ing II backward and to the right. I'm
nediately below the first propellers
are located other propellers working
in the opposite direction. which act
against the counter current OF air
with even greater force and effective
ness than do the first propellcrs. By
this means the ''swirling" of the air. so
fatal to the hopes Of inventors who
have tried the helicopter system in diff
ferent fashions. is done away with.
This scheme also reduces to n mini.
mum the slip" Of tho blade in the air.
even though the blade is stationary.
The center OF the helicopter is at.
tached to a beam thirty-six feet long.
In the center of which Is a pivot, and
the other end OF the beam is set on
scales that record the exact lift. which
amounts to 400 pounds and upward.
Until the airship itself is built. OF
course. the actual practicability OF the
invention cannot be known. Theo-
retically. according to disintcrested
parties who have viewed the demon.
STATIONS, It should work out at least
| to the extent OF raising the machine
into the air, ms the machine and driver
will weigh less than 500 pounds, even
with IA 100 horsepower motor. Steam
! will probably be the motive power.
Care has been taken to provide for
the safe descent OF machine and opcr.
Ator should the mechanism give way
/ or anything break. Also new cover.
| ing, lighter and stronger than any bal
/ loon or flying machine covering ever
! invented, has been conceived by young
/ Cage. This IL now In the patent ap.
piled for" class, As IL the safety float.
! ing device for use In the case OF nc.
cidents to mechanism.
The plan OF driving the hclicoptcr
machine after II rises into the air In
very simple. being merely to turn tho
hclicoptcrs forward, thus giving n
backward ns well as an upward thrust.
and at the same time increasing the
power applied to the propcllers. Thus
/ tho power necessary to overcome the
force OF gravity will be continuous and
the extra force will be applied In
pushing" or pulling" the machine
forward. After q sufficient speed for.
ward has been acquired. the under
part OF the helicoptcr tube Will act M
\ supporting surface against the mir.
thus enabling almost the entire power
OF the hclicoptcr to be used In driving
the machine forward.
Such are the plans and tho claims
OF those Interested. supported by mon
Interested In such affairs and who
have worked out the problem-on pa.
per. An effort will be made TO have
tho ship built and In working trim In
time for the big aero contest In the
East In October.
