What is the name for small rudimentary timers?
A timer is a piece of equipment, or device, for measuring time. Therefore, an egg-timer is a timer, and a clock, in whatever form, is also a timer.Some rudimentary timers/clocks:* An hourglass (or sand timer) has sand in a sealed glass tube with a narrow restriction in the center. Sand in the uppermost chamber flows down through the narrow part into the lower chamber at a slow and fairly constant rate and in a given period of time. The timer can then be turned upside-down to repeat the timing exercise. An egg-timer, normally set to run for three minutes, is an example of this type of timer. * Candle-timer. A candle can have marks at 'hourly' intervals that it burns down to when lit. Or a metal ring with an arm sticking out can be slid down the candle to a pre-determined poit. When the candle burns down, at some point the ring will no longer be held by the candle. It will fall off, with the metal arm striking a bell.* Water clocks. There are various ways of measuring elapsed time with water clocks. * Sun dials (sun clocks). Of all of these, a thirty second 'sand timer' could be the smallest. However, a small rudimentary timer like this can only measure a small mount of time.Some board games contain sand timers. They are used to ensure that all opponents have an equal and fixed maximum time limit in which to complete a task.See Related links below this box for more information.
