SCHATZ
The schatz ships bell clock will have either a pin lever or jeweled lever escape
unit.The older models usually have a pin lever escape unit. It is not an accurate
timekeeper. Anticipate problems with these types. The cups that the balance wheel ride on
usually wear unless they have jewels in them. The fork will often be loose and the pins
will often be worn. Be prepared to jewel or rebush the pivot holes in these balance units.
Unless you are willing to jewel the escape wheel and the verge; and possibly replace
the pins in the pallet, and either reshape the balance wheel pivots or replace the center staff (which may mean making one) ; and either repair or replace the pivot bushing
caps for the balance wheel (again may mean making them) stay away from these types.
The newer units will usually have a jeweled platform escape unit. They are quite accurate
and much more dependable. If they are jeweled , they will usually only need careful
cleaning and timekeeping adjustment.
The catch on the half-hour must pop up in time to catch the hammer end but
not too soon or to will miss it. The shutoff cam must have just let the shutoff drop after
the second hammer drops. Make sure the large cam on the centerpost is in the up
position on the hour trip position .
