Before the common use of electronic clocks in automobiles, automobile clocks had mechanical movements, powered by an electric remontoire. A low power drive spring would be wound every few minutes by a plunger in a solenoid, powered by the vehicle's service battery and activated by a switch when the spring tension got too low. Such clocks were ...
In many clocks, the outer end is attached to a stationary post. The spring is wound up by turning the arbor, and after winding its force turns the arbor the other way to run the clock. The disadvantage of this open spring arrangement is that while the mainspring is being wound, its drive force is removed from the clock movement, so the clock ...
Clocks, regardless of the materials they are made of, are susceptible to damage from incorrect temperatures. Like light, temperature that is too high can cause weakening, discoloration, and or disintegration of organic materials. [16] With wood clocks, temperature is critical to conservation and preservation.
A grandfather clock (also a longcase clock, tall-case clock, grandfather's clock, hall clock or floor clock) is a tall, freestanding, weight-driven pendulum clock, with the pendulum held inside the tower or waist of the case. Clocks of this style are commonly 1.8–2.4 metres (6–8 feet) tall with an enclosed pendulum and weights, suspended by ...
A Florida grandfather preparing to celebrate Thanksgiving with his family and friends was shot to death by his neighbor inside a gated community as the two argued over loud music.
There’s a thin, squiggly tattoo running down the forearm of diligent hospital nurse Floria, always visible past the short sleeves of her royal-blue scrubs, but hard to really get a look at ...
The couple were living with Constantinos Mastakouris, 85, in his New City home when they killed him and left his body in the basement.
When the mainspring is wound up (Fig. 1), all the chain is wrapped around the fusee from bottom to top, and the end going to the barrel comes off the narrow top end of the fusee. So the strong pull of the wound up mainspring is applied to the small end of the fusee, and the torque on the fusee is reduced by the small lever arm of the fusee radius.
