with small circular battery, made OF coneennc
cylinders Of copper aud zinc, which can be INNER
sed in a quart Of calculated waller. Two semicir'
cles Q, strongly magne'zed steel form an entire
circle, interrupted only at the opposite poles
and within the circle, which lies horizontally, the
galvanized iron moves in such manner that It's l.
ron sernens revolve parallel ahd very TO the
ms gnetic circle, aud in the ssme plpne. It's axis
at its upper end is fitted by horizontal cog wheel,
TO another and larger vertica, wheel, 10 whose hUr-
izontal axis a weight is attached ond raised by the
winding o: rope. As soon bs the smallest bat
terry destined 10 generate the power, is properly
connected with the machine, and dolly excited by
diluted acid the motion begins by the horizontal
movement, Of the iron cross, with it's circular seq
mcnt or fnnges. BY the gulvanic connection these
crosses and their connected segments are magnetl-
xed, acquiring north and south polarity al their OPP
pos,e ends and being thus subjected TO the attrac-
ing and repeiling force Of the circular fixed mag
nets. rspid horizontal movement is produced al
the rate Of two hundred to three hundred revolu-
lions in minute, when the small battery was us
ed and over 600 with n calorimotor Of large size.
The rope was wound up with weight OF fourteen
pounds attached, and twealy-cight pounds were
ned from the floor. The movement is instantly
stopped by the breaking Of the connection with the
battery and then reversed by supply interchanging
the connexion Of the wires OF the battery with those
of the machine, ahen il becomes equally rapid IN
the opposite direction.
The machine, as philosophical instrument. OPP
crates with beautiful and surprising effect, and no
reason can be discovered why the motion may not
be indefinitely continued.
