This is achieved by the use of a sliding weight on a pendulum that is moved up or down the arm depending on the required tempo. The main purpose was to provide or assist in keeping a steady tempo and for timing during musical practise. The mechanism of spring driven cogs and wheels, escapement and pendulum has changed little in close to 200 years since the original patent was developed by Maelzel in 1815
