a Remarkably Ingenious Machine
That 1t Cost the Patsntee Two-Hun-
dred Thousand Dollars to haven't aud
Perfect-It Is World Wide Famous
and OF Priceless Value for Mines,
Railroads. City Streets and Country
Roads.
Among the many interesting things
available to Wilmington slght-viewers
is the movable rock breaker now To-
Gated at Fourth and Broumo streets.
A thirty horse power steam engine
drives perpendicular revolving aud
Ryrating machine weighing Six tons,
with All easy capacity OF crushing $50
tons OF our hard and famous Brandy
wine granite in ten hours, ass il Oper-
ators truly testify. 1t can crush 200
tons OF limestone in that time.
As now situated near the places Of
supply and depUsit eleven oue.horse
dump teams suffice to supply and
deliver Tor It. The big rocks, not ex-
ceedink in. l5in. in size, with about
1850 lbs. to the load, are dumped In ut
the top while the little rocks are drawn
away by the teams on "a level nearly 30
feet below. Seventeen mon are thus
employed. Including the gentlenanly
and Intelligent engineer, MIR. George
flick, who takes much interest in the
remarkable machine.
No. 8, OF the same patent, weighs
t9,t00 pounds, will receive rocks not
esceeding ISL in. 92in. as fast as thuy
can be dumped 10y u continuous train
OF cars Into the hopper, eleven feet In
diameter. with a capacity in full of
turning out 1900 tons iii 10 hours when
driven by a l50-hoIse power steam en-
CINE. This size can be seen in opera
zion at the Cambria Iron Works, Birm-
ihgham, Pa.
The inventor OF this machine must
pave remarkably valuable head on
Lis shoulders. He is said to have ex-
pended 500, C00.C0 while inyenting and
kerfecting 1t. Considering the Use

Streets, county roads, etc. all over the
world, we would not take mil.
