This is a very straightforward method for the basic
adjustment and synchronisation of the striking pattern of these
countwheel system is found in many thousands of French, German,
British and American clocks from almost all the years that clocks
were made up to about 1950. After that time most, but not
all, used the Rack/Snail system where the mechanisms of Time and
Strike are combined. However the countwheel did persist for
many years after 1950 so they are not uncommon.
people own a clock, usually quite old, where sometimes for no
apparant reason the striking becomes incorrect with the time as
shown on the dial. If you experience this problem then you
are almost certain to own a "countwheel" clock rather
than a "rack and snail" type.
countwheel mechanism does not automatically correct itself when
the striking becomes incorrect. However, it is an easy
procedure that might take a little practice initially but soon
makes the need to call out your clockmaker un-necessary.
This is an adaptation of the well tried and tested Lever
Escapement as found in most modern watches and many carriage
clocks and chronometers. In place of the pendulum we find a large
balance wheel which is positioned to turn in the horizontal plane
and secured in a slot in the top of the back plate of the
movement. The balance operates a pin pallet escapement, which in
turn runs the Going train of the clock.

Notes to Assist the Owner in Adjusting the Rate and Setting
These clocks are traditional and are found in their thousands in
homes and offices - Wall Clocks, Mantel Clocks from early in the
1900's right through the 30s 40s 50s to the present day.
Also the traditional "Grandfather" or more correctly
known as the Longcase Clock. These often are silent for the
want of a very simple adjustment.
notes are given as step-by-step methods that I use myself when
dealing with these clocks for my customers.
notes are not complex but will assist both the ordinary
householder clock owner and the Home Enthusiast who is keen to
look after personal clocks and who seeks detailed information.
