A torsion pendulum clock, more commonly known as an anniversary clock or 400-day clock, is a mechanical clock which keeps time with a mechanism called a torsion pendulum. This is a weighted disk or wheel, often a decorative wheel with three or four chrome balls on ornate spokes, suspended by a thin wire or ribbon called a torsion spring (also ...
While being set, it is turned by the setting mechanism – in modern clocks, a setting knob on the back of the clock. In watches during setting it is turned by the minute wheel, which is turned by the keyless works. In older clocks the setting was done by opening the face and manually pushing the minute hand which rotated the cannon pinion ...

Mason was known for constructing longcase clocks with eight-day movements, with two keyholes on either side of the dial. They were driven by two weights; one driving the pendulum and the other the striking mechanism. His clock faces were always signed Tim Mason. He was known to be working at an address given as Lords Street in Gainsborough.

A separate set of wheels, the motion work, divides the motion of the minute hand by 12 to move the hour hand and in watches another set, the keyless work, allows the hands to be set. Escapement An escapement is a mechanism that allows the wheel train to advance, or escape a fixed amount with each swing of the balance wheel or pendulum.
As clocks were made smaller, first as bracket clocks and lantern clocks and then as the first large watches after 1500, balance wheels began to be used in place of foliots. [8] Since more of its weight is located on the rim away from the axis, a balance wheel could have a larger moment of inertia than a foliot of the same size, and keep better ...
