URGOS 9 TUBE CABLE DRIVE FLOOR CLOCK
This mechanism is nothing like the Herschede 9 tube clock. Except for the
differential like gear system on the chime side the rest of the mechanism is like the
standard rod chime cable drive urgos mechanism. The beveled gear system that drives
the chime must not be tight and the drive shaft that passes through the center of the
hammer lift drum must have the gear on its end PERFECTLY centered in the idler/drive
gears that mesh with the power train and the sequenceing train . Do not forget the
washers that belong on the end of the shafts in the transmission assembly, they are
critical to the centering of the drive gear assembly. Set the chime lock / trip pin on
the warning wheel at the 3 o’clock position EXACTLY , otherwise there will not be
enough governor spin before the first hammer picks up. Be absolutely certain that the
lock position is set accurately , because to change it after the mechanism is together
will mean much wasted time in much dis-assembly because the wheel is buried in the chime hammer assembly and is not readily accessible. Install the tubes
with the weights OFF otherwise they may easily be scratched. Another common
problem is the mechanism jamming up because the dial causes the plates of the
movement to twist slightly when the mount bolts are tightened.Be sure to check for
plenty of slack in the mounting procedure so as to not cause mysterious sudden stoppages.
Regulation:
popular European mechanism balance wheel new style : with large hairspring and
threaded timekeeping adjustment: the small style found on the 130-070 regulates
faster by turning the adjustment screw clockwise. The larger balance wheel
(found on the 050 mechanism) regulates opposite: that is it will run faster by
turning the adjustment screw counterclockwise.
