THE FLOATING BALANCE

 

Formerly, clocks such as the Smiths Enfield Time & Strike and similar units as well as a number of the traditional Westminster Chime Clocks used the pendulum system for regulation.

Whilst it is acknowledged that a well adjusted pendulum escapement will give excellent service and superb time-keeping the system demands positional care and stability at all times. In addition many owners were unable easily to adjust their clock to run 'in beat'. The clock would stop sometimes.

Then a clever invention came to market: The Floating Balance.

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.

The balance arbor or staff [the axle] is a hollow tube with a small jewel at each end and is supported by a fine taut wire running through it. From the upper anchor point is wound a balance spring in a close spiral terminating in a fixture on the surface of the wheel. The spring is coiled in such a way as to prevent the wheel falling all the way down its supporting wire and instead keeps it in suspension. Hence the term 'Floating' balance.

There is nothing for the clock owner to do with this balance other than to avoid any action that will cause damage.

THE BALANCE SPRING MUST NEVER BE OILED.

The rate is regulated by holding carefully the rim of the balance wheel and with a small pair of tweezers moving the inner circular plate with the arms either toward the Fast marker or toward the Slow. The ring is moved TOWARDS the rate to be ACHIEVED. Do not move it too much at a time and try to record what you have done so that further corrections are less of a guess.

With careful handling this balance system will last for many years. It is fairly robust and is very tolerant of out-of-level running positions.

All clocks and watches should be serviced every three years or so.
