POUVILLON RESTORATION PROJECT - February
Removal of Easter calculator, repair of broken pendulum rod, repair
case lock and key
Shown here is the Easter calculator removed from the
clock. This calculator shows eight complications.
Shown here is the pendulum stick and
gilded bob. The bob weighs in at
a very heavy bob for a clock of this size. Many tower clocks have bobs of
this weight. More will be said later on about some characteristics of this
clock having shared features with those of a tower clock. The rod by
contrast weighs in at
So it is not surprising that the pendulum stick could be broken when
mishandled with the bob attached. In fact the stick was already broken
before in another place just above this recent break as can be seen in the
first photo below and to the left of the new repair. We have used the same
repair technique as was used to repair the earlier break.
These photos show the repaired
pendulum stick. The two weights come in at
for the time and
for the strike. Another unusual feature
in that the time weight is heavier than the strike weight; the reverse of
what is the norm for a clock. These are very heavy weights for a clock of
this size and delicacy, however they are quadruple compounded, see photos
below, so the weight that the clock actually 'sees' is only one-fourth of
The pulley sheaves are made of wood. The high compound is made
necessary by the fact that the weights have only a two foot drop available
for a 15 day duration
The repaired pendulum is shown in place.
These photos show the movement's glass case door lock
assembly and the key blank being fitted to the existing lock tumblers. A
separate key will also be made to fit the base rear door lock.
