塔钟
塔钟或公共时钟（英文：Turret clock）是一种比家庭的时钟大很多的时钟,旨在为公众提供可见的时间，比如刻度盘、或者铃声，是一种为公共提供便利的机械装置。塔钟一般安装在建筑的高处，通常是专门建设的，如城镇教堂集会厅，以及其它公共建筑。最初时钟并没有被钟表匠称为塔钟,直到近代,一些老钟才被当地人视为塔钟。
真正的塔钟是机械驱动的，近些年才出现了电力驱动的塔钟，因此它们在塔钟历史上位于比较后的位置。

A turret clock or a public clock is a clock that is larger than a domestic clock and has a mechanism designed to drive a visual time indicator such as dials and or bells as a public amenity. Turret clocks specifically had mechanisms mounted high in a building often a purpose built tower such as churches, town halls, and other public buildings. Clocks were not referred to as turret clocks by clockmakers until recent times, often old clocks were recognised as turret clocks by their location.
