A Plan for PulsatlOn without wind Ou
Steam.

Steam.
Mr.. Isaac Chomel, Of sol Fulton st.
Brooklyn, has invented a plan by whicl
he expects to propel a ship by her owl
rolling motion solely, thus doing ava,
with any other motive power Mr.
Chomel is the inventor of the swinging
berth, by means of which sea-sicknesl
may be Dlleviated, and the application
Of this principle inspired him with tbt
idea Of utilizing it in the production o
power. He has been working towards
the development of this idea for the pasI
three years, and has at last succeeded
in perfecting a working model, 4 feel
II inch beam, and 16 inches deep. he
claims that in his model be has reached
a shape which will secure the maximum
with the minimum of pitching motion.
and from the rolling motion he derives
his power In this model he has con-
strueted, at either end. is a oompart-

ment about eighteen inches in length

hung so as to yield either to the pitch
ing or the rolling motion of the vessel.
This, at its bottom, gears directly upon
the propeller shaft, so that there is the
least possible loss Of power AS this
platform is inclined to an angle Of thirty
degrees, the propeller makes eight rev.
olutions, continuing to revolve in the
same direction when the platform is tilt
ed the other way.
Mr. Ohomel says that a ship at sea
rolls about ten times per minute, and
that he will thus secure in a brisk sea
eighty revolutions per minute His in
tention is to use this power for the trans
portation Of live cattle to Europe. In
a ship 300 feet long be can construct a
platform or stable capable Of containing
about two hundred head of cattle

since this will at all times be horizon

than when they were shipped,

Mr. Chomel has every confidence in
he success of his invention, and Gays

craft fifteen feet long. be will cross the

es to utilize his freight ofcatlle. march

Without expressing any opinion as to
le merit of this invention, it may be
lid that it is well worth an inspection

Mr. Chomel has also invented mag
etic log for determining the speed of
essels. This consists Of small pro-
sllor wheel fixed at the lower part of
le stern, an endless band passing
-sund the shaft of this aud roller at

md is a small piece Of iron, which, as
passes the upper roller is attracted by
magnet and rings bell. There will
J so many turns of the propeller for
ch magnetic revolution. and a certain
stance passed over ky the vessel to
'oduce this number of revolutions
nsequently each strike Of the bell will
dictate this distance N r World. I
