senger Filler, He Says

Fersaking. in his of hours, laughing
gas for hydrogen gas. gold and ANAL
gam for steel tubing and magnolium,
and dental punch drills for electric dy-
namos, DR.. A. J. Thinker is building an
airship Of the heliocopter type. In his
workshop in Turk street near Van Ness
avenue the dentist has practically com
spleted the model Of a heavier than air
machine, which he is now about to
patent From the preliminary model
he viii construct practicable ma
chine WHICH he says can be built at the
cost Of a first class automobile and
which viii transport through the air
with comfort and safety and at a mile
minute from 10 to u passengers
SORT or SKYLARK
The helioeopter is a sort Of skylark
among airships. Not that it sings sweet
mathis Ger mountain and lea, but that,
blithesome and cumberless, it rises
from its nest or moorings straight up
in the air. instead Of having to leap
for life on a derrick, like the Wright
machine, or having slowly to rise on
gradual climb from its bed. as do
dirigible balloons.
q The characteristic of DR.. Hiniker's
: machine is the lifting arrangement It
consists OF two fans, or horizontal pro-
pellers, placed in open drums or shafts
- one directly behind the PROV, the other
near the stern. These propellers are
revolved at a great speed by the en-
gines Of the machine. The force of
their revolutions lifts the machine up
ward TO the desired height
MODEL NEARLY COMPLETED
At present nearly completed in Dr.
Ainiker's workshop is the large model
Of his airship. The model is 81 feet
long, : feet wide. or beam, and ? feet
=. inches deep. The bow comes to a
point but the greatest thickness and
depth is located near the prov. From
that point the body Of the machine
/. tapers of toward the tail, as a whales
architecture is arranged. That shape
lessons the resistance of the air. The
frame is OF spruce wood, made rigid
with piano wire, 10 be covered with
.sSheet magnolium. At present the fans
g are reVolved by electric power, con-
veyed TO the machine by a chain. Yes
terday afternoon DR.. Thinker started
his dynamo, and with about one horse
power revolved the fans and lifted the
machine, which weighed about so
pounds, of the bench and into the air
% In the perfected machine the power will
%. be gasoline, and the engine, of course
viii be located in the car.
DR.. Thinker and ". S. Arnold worked
Up the plans for the new machine, but
8. the patent rights viii be in the name
o.. Of DR.. Thinker.
WILL CONSTRUCT MACHINE
I am satisfied now with the model"
said DR.. Thinker yesterday. and I will
start directly on the practicable Una
chine. The machine I viii build viii be
120 feet long. 40 feet wide and about
I3 feet deep at the broadest point. The
frame win be made of spruce. steel
tubing and magnOlium, a metal made
in Germany by a secret process, as
light as aluminium and more malleable.
Magnolium viii cover the frame. The
machine viii be equipped with 8 foot
fans and viii have a total weight Of
1000 pounds. The fans win be used for
eievating the airship TO the desired al
titude
There viii be propellers in the stern,
which viii drive the machine, and
aeroplanes 10 support it. Encased in
the sections Of the frame viii be dis
connected gas bags, with a lifting
power able 10 sustain about half the
weight Of the machine. The aeroplanes
and the propeller viii buoy the
machine
such car viii carry about 10 or
Il passengers. It can be built for
about the cost Of high class auto
mobile
The value Of the heliocopter type OF
machine is that it can be raised from
city lot or street and does not have
10 have a free way IN which TO glide.
The car can be made waterproof, so that
the machine can lower into the water
without danger to the occupants. In
six months expect 10 have my airship
completed and in operation"
