Because there are 45 minutes in each half with an addition time added at the end of each 45 minute half for any time that they stopped the game during that half for an injury, an altercation, to clean something up that a fan threw on the field, etc...So they may add an additional 3 or 4 minutes to a half and its easier to count up to 49 minutes for example, rather than minus 4 minutes.
The wind up device should be behind the face of the clock.
Wind
Peter Henlein, a German locksmith and clockmaker, is credited with inventing the first portable spring-driven clock in the 16th century, which is considered one of the first types of wind-up clocks.
A wind up clock can be purchased in many different places online and in retail stores. Depending on what design you want on your clock will dictate where the purchase is made.
A wind-up clock stores potential energy in a wound-up spring. When the spring is released, this potential energy is converted into kinetic energy, which drives the gears and hands of the clock to move and keep time.
first there were wind up clock, the battery opporated clock, and now electric clocks
"wound the clock" is past tense.
To wind up a 3-hole Gilbert clock, first locate the winding arbor keyholes on the clock face. Insert the winding key into each keyhole and turn it clockwise until you feel resistance, indicating that the clock spring is fully wound. Be careful not to overwind the clock, as this can damage the mechanism.
Wind-up clocks to digital is one of the best.
To wind the clock in the Deltora Quest game, navigate to the clock in the game's interface and click on it. This action will prompt you to wind the clock manually by using your mouse to rotate the clock's hands in a clockwise direction until the clock is fully wound.
on a vintage 20's sessions clock how long is the wind good for?
You wind up a spring and a notched wheel makes the clock tick consistantly. the hands move with the mechanism to make the clock move a little bit every minute. (The spring is tightened when you wind it up) +++ The "notched wheel" is part of the "escapement", which does indeed control the speed, but the actual controlling influence in a mechanical clock is what that wheel drives and in turn returns the compliment by locking and releasing the wheel at a set rate. And that is the harmonic-motion properties of either a coiled spring attached to a miniature flywheel called the 'balance wheel', or of a pendulum.
