ROLLING ACROSS THE OCEAN.
A PLAN FOR PRopULsATIoN WITHOUT
WIND OR STEAM.


WIND OR STEAM.
Mr.. Isaac Chomel. of 5O1 Fulton street
Brooklyn, has invented plan by which
he expects to propel a shIp by her own
rolling motion solely; thus doing away
With any other motive power. Mr.,
Chomel is the inventor of the swinging
berth, by means of which sea-sickness
may be alleviated, and the application Of
this principle inspired him with the idea
of utilizing it in the production of DOW
er. He has been working towards the
development of this idea for the past
three years, and has at last succeeded in
perfecting working model, 4 feet II in.
beam, and 16 inches deep. He claims
that in his model he has reached shape
which will secure the maximum with the
minimum of pitching motion, and from
the rolling motion be derives his power.
In this model he has. constructed, at either
end, is compartment air and water
tight. In the centre of the hull is a wa
ter-hght compartment about eighteen
inches IN length. In this suspended a
movable platform, hung so as to yeild
either to ht pitching or the rolling mo-
ton Of the vessel nThis, atlits bottom,
gears directly upon the propeller shaft,
so that there is the least possible loss of
power. AS this platform in inclined to
an angle of thirty degrees, the propeller

revolve in the same direction when the
platform is tilted the other way.
Mr.. Chomel says that ship at sea rolls
about ten times per minute, and that he
will thus secure in a brisk sea eighty rev.
olutions per minute. His intention Is to
use this power for the transportation of
live cattle to Europe. In ship 800 feet
long he can constructs a platform or stable
capable of containing about two hundred
head of c1tfIa planad this Mat
form the motion of the ship will
not affect them at all, since this
will at all times be horizontal, and
he claims that he will be able to land
his cattle in as good, or better, condition
than when they were shipped, and to car
ry them over for absolutely no expense
except their food and care and very
moderate charge for freight. .,fq- =
Mr.. Chomel has every confidence in
the success of his invention, and says that
if he can procure the means to build
craft fifteen feet long, he will cross the
ocean in her. As soon as the weather
becomes milder Mr.. Ohomel will test his
present model in the waters of the bay,
and if it works there satisfactorily he has
been assured that the means shall be
forthcoming to try it on larger scale.
In smooth water, when there is no rolling
motion, Mr.. Ch0mel proposes to utilize
his freight of cattle, marching them from
side to side and thus obtaining his power
by moving the platform instead of the
ship. .-I-
Without expressing any opinion as to
| the merit of this invention, it may be
said that it is well worth an ninspection by
| experts in motive power.
Mr.. Chomel has also invented mag
netic log for determining the speed of
vessels. This consists of small propel-
lor wheel fixed at the lower part of the

small piece of iron, which as it passes the
upper roller is attracted by magnet and
rings bell. There win be SO many
turns of the propeller for each magnetic
revolution, and certain distance passed
over by the vessel to produce this num-
Der of revolutions; consequently each
strike of the bell will indicate this dis
