fitted with a steel plate caisson, which forms the inside of
the turret, and carries the rotating shell and its plating.
The central tube is formed of steel plates, partly cylindri-
cal and partly in the shape of a truncated cone, protected
by armour ; the two parts being joined together by a cast-
steel angle-ring. The top part of the tube is connectée!
The hydraulie cylinder at thefoot of the central tube forms
a pivot on wbieh the greater part of the revolving weight
rests, and which enables the turret to be raised for inspec-
tion of the rollers. The rotating mechanism contains the
set of conical horizontal rollers on which rests part of
the weight of the platform, and the set of cylindrical
vertical rollers which insures the centring of the system.
