iNVENTS A SAFE SHIP.
This Marine Engineer Designs 6
Really Unsuitable Vessel.

Readers of the News will remember that
among the persons prominently identified
with the Titanic was Captain q. 4.
Chaddock, a veteran sea captain and ma
rine engineer of Liverpool. Captain
Chaddock now has designed what he
conceives to be a practically unsuitable
ship.
In the old days of wooden ships built
without internal subdivision said Cap
tain Craddock TO the correspondent OF
the Chicago Daily News, Incoming

I'm order to do away with the dangers

ship from sinking by forming not mere

inner bottom, but by dividing the hold OF
the ship into a series of air and water
tight compartments, to which access is
had by hatchway chambers closable bs
matches, in an air and water-tight man
ner, and by providing a system of piping
for charging these compartments or any
of them with air under pressure in cases
of emergency. so as to recover lost buoy
