Cousin of Messrs. Sperry
Here Discusses an I'm
portant Subject.

The following concerning an inter
cstinE lecture by Elmer a. Sperfy. a
cousin OF Captain NJ. G.. and Attorney
c. b. Sperry. OF this city. recently APP
peared in the New York sun:
The wonders of the syroscope were
limited at by Elmer a. Sperry at the
meeting of the Naval architects and
marine engineers at the engineering
societies building, at 90 West Thirty
Ninth street. yesterday. He told how
ships could be made to keep an even
keel in a heavy sea and how the gyro-
scopic force was applied to the COM
pass.
The meeting was the second day ses-
sion of the annual gathering OF the
naval men for the presentation of
their scientific. papers on a wide range
of Subjects Besides the EyroscoPe
such subjects were discussed as the re-
ductton OF loss by fire aboard ship.
the use of producer gas as motive
power and cOaling warships.
when the motive power of vessels
changed from an upsettinE force Che
saiD to one almost exclusively OF for
ward thrust said Mr.. Sperry. the
design Of ships underwent quite radt-
cal changes in connection with lines
affecting the stability, decreasing this
factor and favorinS decreased resis-
Tcnce, aiding the attainment of high
or speeds. Now that stability may be
impaired to n structure OF naturally
small rLghting movement we are on
the eve of even more radical
changes in design.
THE problem is to hold the ship
from rolling by neutralizinE with the
rsyroscope each disturbing influence
as it reaches the ship while awaiting
themselves of all the aid possible
through the design of the hull and the
disposition of the masses. A
great many ships as they now stand
could with profit utilize the gyroscope
steadying gear which is at present
available and some important install
la lions are now being contemplated"
Mr.. sperry told OF seeing Russian

tons of water siushing hack and forth

act the roll OF the ship so as to make
h possible to operate the guns on a

has to be timed to the roll of the sea.

The question is often asked: WY Is
a r.yroscope better than n moving
weight in ship for roll auenching!

the Cyro can be made to do the work

rccted in any desired line or plane
whereas when we use water or any
other form of moving weight each
pound represents n pound only ana
can do the work of only a pound and
only in vertical direction"
Mr., sperry gave a very interesting
though strictly scientific de1nonstra-
tion of the peculiar faculty possessed
nv the ssyroscope which made it pos
sible to transfer energy around a cor

gyroscope to ship with one. The
model ship in a smooth surface Is tilt
ed to an angle of 25 degrees and then
allowed to rock itself to an even keel
The diagram showed that the snip
with the active Eyroscope made ABOUT
three rocks in each direction and then
spr3 denly became SO steady that a man
could shave or play billiards, while
the ship without it rocked labortous-

Mr.. sperry praised the work OF
Capt. d. w. Taylor in the washington
navy yard in respect to the Eyro and
said that his treatise on the subject
was of immense value toward the un-
.derstandInE and practical application
