LTBERTY BELLPATCH.
The Cracked narbineer of Liberty May Be

The old cracked bell hanging idle ana
useless In Independence Han may some
day soon be made 90 lit up us long stii-
ed voice and ring out ll all its useful
yieOr. Early In the present century the
efforts OF inventors, bell mOuldcrs ana
metal workers were directed 10 the ac-
cOmphshment Of this end, hut without
avail Lattery the same EFFORTS We're
made 10 mend ether bells that had be-
come dumb. but an without any fruitful
results and 10 was generally agreed mat
a cracked bell was worth only so mucn
a pound as Old metal.
4 system Of electric wedding has been
devised by a Russian, SlayianOm, by
which OLD bells cracked 10 the very crown
may be made as new. The new process
Is known as the Observation-Disclosures
and 10 appears 10 offer interesting posal-
blllues. though not yet fully developed.
It's principle depends on the employment
of bath and IN the development or
hydrogen gas az the negative pole. The
gas surrounds the part or the object 10
be treated. forming a high resistance 20
the current, which is transformed az THIS
point into calOriiic energy ana cOmmuni-
Gated TO the metal or other object form
ing the ncga tive pole.
This method Is said % be an improve
ment on the methods of both thomson
and BenardOs, which are well knOWa TO
metal workers, and IL has been in Sic
cessiul operation for some time at the
Perm Gun Works. IN Russia.
The essential principle Of he SlayiauOfr
system Is contained IN the supply OF mol
ten metal 10 the fractured part Of the
same nature as that Of which the object

the SlaVianOff system are Of metal. enc

be operated on. the other by metal Of the
same kind I'm the form OF a circular bar,
which. during the operation. Is gradually
melted down. The range Of work which
can be successfully undertaken by his
method Is very great. The instance OF
the bell nendng. offers almost an m
serarable difficulty 10 even the laest
practice OF other systems IN this direc-
ton.
The process IS described to be. IN all
its details. says the Western Electrician,
one OF the greatest certainty. ease and
convenience The metal electr0de afford

eulating by means OF a spring and sOien-

occupies but little space. and IS so ar
ranged that in case OF an accident 10 the
dynamo the workman can at once throw
the whole apparatus out OF operation. In
addition TO the regulating mechanism re-
ferred 20. there is a solenOid. and also a
