In order to successfully run out the clock by kneeling, there must be less than 40 seconds on the clock if the opponent has two time-outs, 1 minute 20 seconds if the opponent has one time-out, or 2 minutes if the defense has no time-outs remaining, at the snap on a first down (an additional 40 seconds can be run off if the clock keeps running ...
A Roskopf, pin-lever, or pin-pallet escapement is an inexpensive, less accurate version of the lever escapement, used in mechanical alarm clocks, kitchen timers, mantel clocks and, until the 1970s, cheap watches now known as pin lever watches. It was popularized by German watchmaker Georges Frederic Roskopf in its "proletarian watch" from 1867 ...
In Canadian football, the three-minute warning is given when three minutes of game time remain on the game clock in the first and second halves of a game. (If the ball is in play when the clock reaches 3:00, the three-minute warning is given immediately after the ball is declared dead.) The three-minute warning stops the game clock in all cases.
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...

The anchor escapement was so named because one of its principal parts is shaped vaguely like a ship's anchor.
Huygens' maintaining power in use. The weight drive used by Christiaan Huygens in his early clocks acts as a maintaining power. In this layout, the weight which drives the clock is carried on a pulley and the cord (or chain) supporting the weight is wrapped around the main driving wheel on one side and the rewinding wheel on the other.
