A spring remontoire uses a spring. It is the only type which can be used in watches, since the force of a weight would be disturbed by motions of the wearer's wrist; An electric remontoire can be either a gravity or spring type. In it, the weight or spring is rewound electrically, with a motor or solenoid. It is used in clocks with traditional ...
Intermatic Incorporated is an American manufacturer of time switches headquartered in Spring Grove, Illinois. Intermatic was founded in 1891 in Chicago, Illinois as the International Register Company to produce fare registers .
A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.
However, whereas the spring or the weight provided the motive power, the pendulum merely controlled the rate of release of that power via some escape mechanism (an escapement) at a regulated rate. The Smithsonian Institution has in its collection a clockwork monk, about 15 in (380 mm) high, possibly dating as early as 1560. The monk is driven ...
A gravity escapement uses a small weight or a weak spring to give an impulse directly to the pendulum. The earliest form consisted of two arms which were pivoted very close to the suspension spring of the pendulum with one arm on each side of the pendulum. Each arm carried a small deadbeat pallet with an angled plane leading to it.
His clocks of the period used a grasshopper escapement which malfunctioned if not driven continuously—even while the clock was being wound. In essence, the maintaining power consists of a disc between the driving drum of the clock and the great wheel. The drum drives the disc, and a spring attached to the disc drives the great wheel.
