Gothic weight-driven clocks needed to be positioned so that the weights had room to fall. This was usually done by standing the clock on a bracket or hollow pillar. A simplification was to provide a hanging loop at the back of the clock and spurs to grip the wall and keep the clock in position. This idea was often used on English lantern clocks, but the method is less practical and even dangerous the heavier the clock becomes. The hanging clock therefore is usually limited to the lighter type such as the south German or Austrian Telleruhr. (A hooded clock is not a hanging clock, which inplies that the clock movement itself hangs, not its case. ) Sometimes small spring-driven clocks in the shape of Gothic clocks or table clocks of tower form were hung from a small chain fastened above the cupola.
