Later the mirror, especially if it is circular and convex, may be called girandole by itself without the candle holders. [3] The wall-mounted lighting device is a common definition of girandole in English today. [13] [5] [14] Some large dressing glasses of the 19th century were known as "girandoles" because of the lighting devices mounted to ...
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
A mechanical movement contains all the moving parts of a watch or clock except the hands, and in the case of pendulum clocks, the pendulum and driving weights. The movement is made of the following components: [2] Power source Either a mainspring, or a weight suspended from a cord wrapped around a pulley.
A building's surface detailing, inside and outside, often includes decorative moulding, and these often contain ogee-shaped profiles—consisting (from low to high) of a concave arc flowing into a convex arc, with vertical ends; if the lower curve is convex and higher one concave, this is known as a Roman ogee, although frequently the terms are used interchangeably and for a variety of other ...
Fillet geometry, when on an interior corner is a line of concave function, whereas a fillet on an exterior corner is a line of convex function (in these cases, fillets are typically referred to as rounds). Fillets commonly appear on welded, soldered, or brazed joints.
2. The gear trains used in clocks and watches have multiple stages of wheels and pinions in which the pinions have few leaves. Involute designs for these leaves would be undercut, making them too fragile and difficult to manufacture. 3. A large aspect of the design of watch and clock movements is the minimisation of friction.
The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each swing, and allows the clock's wheels to advance a fixed amount with each swing, moving the clock's hands forward. The anchor escapement was so named because one of its principal parts is shaped vaguely like a ship's anchor.
