once created boat intended to be sailed.
rowed or propelled like bicycle, and
while he was a motorman on the San
Mateo electric road he devised trolley
that wouldn't slip and track brake that
would stop any car in five feet.
But he thinks that he has achieved sue
cess at last He realizes in advance that
it is plain that his alrship will go to New
York in thirty-six hours and local capi-
talist is waiting to see his model work be-
fore putting up the $4,000 needed TO build
one hundred feet or so long.
The Stanley airship has been patented,
and so it has become new invention, and
then airsh.p ideas are all interesting.
This one consists of the familiar aluminium
cylinder filled with gas and driven with
propellers, and the inventor depends on
his new devices for its success.
The upper four fifths of the alum mum
cylinder consists of compartments to be
filled with gas, and the rest affords sort
of basement for machinery, freight and
passengers. Mr. Stanley figures out that
with>a cylinder, the main part of which is
100 feet long and 40 feet in diameter, he
will have a weight of ship and machinery
of 5000 pounds and buoyancy of 5000
pounds, leaving margin OF nearly
ton for passengers, baggage and freight.
This buoyant body is to be moved
through the air by two propellers, at front
and rear, the front one hauling on the ship
and the rear one pushing. The machin-
cry in the lower part OF The cylinder will
consist of an engine of great lightness to
use some power yet undecided upon, and
the necessary shaftlng, gearing, etc.
The front propeller is one OF Mr.. Stanley's
novelties, he says; but the TWO chief inn
provements on the other alumni cylin-
der plans are horizontal propellers above
and the aeropanes on. the side. The
great inconvenience about airships is the
necessity for alignting now and then, and
it is recognized BY all eirship inventors
that alighting on the foreign element be-
low is something worthy OF grave consid-
Grafton. 1t must be done with gentleness
and in good order. for a great airship
thrashing around amid blasts and barDed-
wire fences would be a saddening spec
tacle.
Most airship inventors count on swoop-
ing close to the earth and poi'ng dell
cately while anchors and hawsers are
thrown out and made fast, whereupon he
great fabric may be lashed down. But
there is great danger in anchoring on the
swoop and poise, and Mr.. Stan!ey's hori-
zontal propellers solve the difficulty.
When the buoyant ship is fairly over the
depot area these propeliers will steadily
and with any needed degree of genteness
force the ship downward to the anchorage
while the other propellers hold the
nozzle against the wind.
Tnere is rudder for lateral steering
and side aeropianes. or rather rude for
turning the ship upward or downward.
o her inventors have fixed one big rudder
on the side for this purpose, but Mr.. STAN
ley says that they would tilt the ship to
the angle of the incline of the course, and
he will have three or more working syn
enormously, but Of diff .rent sizes, with the
largest behind. Thus the ship will main
tain horizontal position.
The pilot will stand in the front part Of
the cylinder with windows below, above
and about him, with his hand on the rud-
der-wheel ana by an engineers signal
cord and two levers. These levers will
work the side rudders Now, when the
pilot wants to turn to one side very
and throw the planes on one side into a
vertical position. They will t.us act like
one oar in the water, retarding The prog
ress OF one side and adding to the effect of
the rudder behind.
The whole device is rather simple, and
Mr.. Stanley says that he is so sure that it
will work that if he had the money, he
would put every cent into big one with
out wasting any of it OH experiM en- tal
models. The details of providing state
rooms and for passengers, etc., will come
later.
II estimate that this ship would go to
New York in thirty-six hours" said MIR.
Stanley yesterday. "There would possibly
be two or three stops on the way with
Vacant lois fixed up for landing, though
they needn't be large, and two men would
be enough at the depot grounds. We
would right away get the contract for
carving the United States mails and wit IN
the saving in time, rich people would nay
more an they would on the cars. Our
operating expenses would be- next to
nothing. For safety. would rather ride
on that airship than on motor car"
Mr.. Stanley is building model one foot
long TO work by clock work. TIE patent
was secured February 6, by Attorney c.
H. Hubbs, and the invention is now
among the airships of the Patent Office.
