- Victorian Period - The Victorian period of furniture and decorative arts design covers the reign of Queen Victoria from 1837 to 1901. There was not one dominant style of furniture in the Victorian period. Designers used and modified many historical styles such as Gothic, Tudor, Elizabethan, English Rococo, Neoclassical and others, although use of some styles, such as English Rococo and Gothic tended to dominate the furniture manufacture of the period.
The Victorian period was preceded by the Regency and William IV periods, and followed by the Edwardian period, named for Edward VII (1841 ? 1910) who was King of the United Kingdom and the British Dominions and Emperor of India for the brief period from 1901 until his death in 1910.
- Duplex Escapement - A duplex escapement is used in clocks and watches to control the release of energy from the mainspring to the timekeeping mechanism. The duplex escapement is a variation of the lever escapement and is characterized by the use of two pallets, or escape wheels, to control the release of energy.
In a duplex escapement, the balance wheel, which oscillates back and forth, alternately pushes against the two pallets. This allows the energy stored in the mainspring to be transferred to the balance wheel in a controlled manner, keeping the timekeeping mechanism accurate.
One of the advantages of the duplex escapement is its relatively low friction, which helps to maintain accurate timekeeping and prolong the life of the clock or watch. Additionally, the duplex escapement is relatively easy to maintain and repair, making it a popular choice for clockmakers.
- Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
- Barrel (in a Clock) - In a clock or watch, the barrel is a cylindrical component that stores the energy from the mainspring. As the mainspring is wound, it stores energy in the barrel. As the clock or watch runs, the energy is gradually released from the barrel, turning the clock's gears and keeping the time.
The barrel is typically located near the centre of the movement (the mechanism that powers the clock) and is connected to the center wheel, which drives the rest of the gears. The barrel typically has teeth on its outer surface that mesh with the gears in the movement, allowing it to transmit energy to the rest of the clock. Some barrels are designed to be wound by hand, while others are automatically wound by the motion of the wearer's arm.
