.!ibut It was not until some year
later that public enthusiasm wa
laroused through the suecessful triar
1of monorail car balanced Eyro
scopicalIy.
The great possilIfI the gyro
scope Of the future have heel
clearly brought ont by Mr. sperr1
i'm paper read before the American
fsociety of Naval Architects and
Marine Engineers ana afterwardl
! published in the London Engineer.
ing. He says:
Every pound In the rotating mass
OF gyroscope can easily be made, t.
do the work OF $50 to 200 pounds.
The gyroscope IS probably the only
device in the world by means Of
which stresses and also energy may
be transmitted around a corner SO
to speak. With the gyroscope 1t Is
possible. to create ana mafhtain a
very powerful fuIcrnm in space eff
fectiYe for the heaviest kind OF me-
chanical duty
Nov, on board ship there is one
factor that Is stiR and Is. now avail
able. and that is the fore and aft
stability of the ship. In the gyro-
scope for the first time we have the
possibilities Of reaching out and
transferring this stability around a
corner, so to speak. to the athwart-
ship plane and thus hold the ship
against rolling. we can do this with
a surprisingly small mass, because.
as have said, every pound of the
mass can be made to do very large
amount of work, owing to the vefoc-
ity that may, at a low cost, be inn
pressed upon It. with the active
type of gyroscope we ind that a.
small part of one per cent of the dis
placement OF ship will perform 81
very substantial service, down to the
point of practically fully extinguish-
ing the rolling
WORKING in this line Mr.. Sperry
continues after. mentioning the
avoidance of using mercury, II have
found simple details by means OF
which the whole gyroscope PROPOSE
ton is reduced to strictly meehan-
icaI basis, easily within the eompre-
of ali and containing no un-
known Quantities, and corresponds
ingIy easily dealt with. In the gases
where the gyroscope is employed asl
a battle compass the apparatus Is
pIaced below decks, and small M
about the size OF an ordi-
nary compass are distributed I'M diff
ferent positions on the ship, giving
the exact Indications of the gyro-
scopic compass itself.
my work has extended to a point
where action OF such Instruments
can be controlled from the gyro-
scopic compass and distributed as
desired, the Indications being accu-l
rate to a small fraction of a, single
degree. Many observations have
been made indicating that they are
accurate to 36-100 of an entire Girl
Gle. Among the points never before
realized is the automatic connection
Of the northerly or southerly compo-
nent of vessels speed at sea, this
correction being made between the
Zyroscopic compass and its transmit
ling member in such a manner that |
he indications received by the nav
gator and elsewhere about the ship
are thus absolute and maintain true
north.
TT will be understood that this
type of compass is not affected in
The slightest degree by the steel OF
he ship or cargo, nor any mag
letic disturbances in. either; neither
should shifting cargo, turning tur-
cts or gunfire, or the striking OF
ship by shot, disturb its accuracy
,r reliability, nor is it affected In the
slightest by those disturbances tecn-
l!caHy known as deviation or varta-
ion
