A WONDERFUL MOTOR.

Has Been Utilised.
T. A. Tarbox, of Asbbyburg, Mass, has
discovered form of motor power which
he thinks is destined to cast steam and
electricity into the shade, says the Louis
vile Co~rier-Journal. The form Of power
which he proposes to utilize is simple
enough, being simply an extension of the
spring system of clocks and watches. He
has observed that spring 1nwinding
slowly gives the same power as at any in
creased rate, and on this characteristic
his invention is based. It is capable of
almost indefinite extension, and can be ap-
Piled to any system of machinery requir-
Ing greater or less power. For ordinary
purposes, however, 10 springs, each from
~ to horse power, are used. These are
placed on spools, which in turn are mount
ed on cylindrical shaft. When they are
wound up. they are kept from unwinding
by dog which fits over each spring, and
which can be released or applied at the
WILL OF the person in charge. The winding
II done with small key, and requires no
great exertion of strength.
This is all there is about the system. To
utilize the power obtained by the uneoil-
ing of the springs all that is necessary is
for gearing to be attached to the shaft,
when any machinery needed may be at
once started into action by starting the
dogs.
II can apply any amount of power I
want" explained the inventor. 'sTo do
this it is not necessary to enlarge the
springs, as when beyond certain dimen-
slons and strength they become clumsy
The ones 1 expect most to employ are
those of from one to two horse power, as
these are the most convenient for winding.
One of fve-horse power would be too un-
wieldy, but two of half the power would
amount to exactly the same. Consequently,
when need more force 1 simply add more
springs, and do this to any extent in rea-
son. small spring can be utilized to
the full extent of its power when placed
by large one, and this property is also
made use of. Another feature is tce fact
that spring, if wound up, exerts as much
power before it starts uncoiling as when
running down.
I'm my system the springs require
about three hours to run down. Their
power begins weakening as soon as half
run down, consequently I find it necessary
to begin winding up when about third
uncoiled. To do this, the spring is un-
shipped, the key applied, and in from two
to i've minutes it is wound and ready for
running. As soon as it is started, another
one is taken up, and SO on until all have
been attended to. By this means the
power is always uniform.
II can apply my invention to anything
where electricity or steam can be employ
| ed, and it has the advantage of perfect
safety as well as great economy, it requir-
ing nothing but the simplest running gear
| while any child can run it after being once
| instructed. One of The first things to
which mean to apply it is steam thresh
ers and harveste-s. 1t will be without
danger, more effective and less liable te
get out of order than steam engine. II
| can also be used on boats and in any Other
place. The first thing, however, on which
my invention is meant 30 be used will be
street cars. As soon as my patent is OBJ
tanned will have car fitted up, which
mean to operate over the different roads
OF the city at once.
