/ is any one tool that ia more indispen.
/ sable than the rest il is the pneumatic
/ hammer, which makes possible the
various and difficult forms OF riveting,
callling and chiseling. This hammer
consists OF cylinder in which piston
reciprocates. delivering II continuous
| series of blows against the end of the
/ die. The hammer is light and pow
erful. For small rivets it can be held
/ in the hand, but for heavier work it is
supplied with n yoke support, and
| thus fitted it will drive aud fit the
largest size rivets in use, which are
! generally one-inch in diam ter. Prob.
ably the hardest manual labor in ship
and bridge building is rivetiug. Com
bined with this is an amount of tech
meal skill acquired only by long and
arduous apprenticeship, and varying
with the class Of rivetg driven. In
addition the necessity for heavier
/ plating. doublinSs, etc, requires the
use of larger and longer riyets, which
cannot be properly closed down by
hand. The pneumatic hammer is the
practical device which has enabled
| builders to surmount these and other
obstacles. The air tool also saves
money.
1;oLIAN CHIMES.
New York may know That in the
chimes of ST. Patrick's Cathedral on
Fifth avenue, the city possesses one
of he finest orchestras of this kind in
the world, but does New York know
! that these bells are now rung by COM
| pressed Dir? Nineteen bells, the
heaviest of which weighs about six
! thousand pounds. the lightest about
three hundred pounds, con stitute the
set, viii CHI has been placed in the
northern spire, $50 feet above ground.
Electricity is the trigger, and COM
| pressed air the power in this opera
ton. The largest orchestral chime in
| the world is that of the church of St.
| German L'AuXerrois in Paris, which
set was finished in 1873. Their con-
struction consumed fifteen years, but
! they never ran successfully until last
