Mechanical Desk
A mechanical desk is usually an antique desk type which was produced during the 18th or the 19th century. At one extreme there are desks furnished with a multitude of panels that swing out while stacks of small drawers pop up when a user lowers or extracts the main writing surface or desktop from a closed position, thanks to some well placed levers and gears. At the other extreme are mechanically simple desks like the Wooton desk whose two panels open up separately by hand and whose desktop is also opened in a separate manual operation, without exploiting any gears or levers. The term is used quite loosely. There was an explosion of mechanical desk designs in the second part of the 18th century. This came at the same time as a renewed interest in smaller domestic furniture in the homes of the rich, and the general introduction in their homes of all kinds of new mechanical devices such as small clocks and wood turning tools. These devices are described in the ''Encyclopédie'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desk
A desk or bureau is a piece of furniture with a flat table (furniture), table-style work surface used in a school, office, home or the like for academic, professional or domestic activities such as reading (activity), reading, writing, or using equipment such as a computer. Desks often have one or more Drawer (furniture), drawers, compartments, or pigeonholes to store items such as office supplies and papers. Desks are usually made of wood or metal, although materials such as glass are sometimes seen. Some desks have the form of a table (furniture), table, although usually only one side of a desk is suitable to sit at (there are some exceptions, such as a partners desk) Some desks do not have the form of a table, for instance, an armoire desk is a desk built within a large wardrobe-like cabinet (furniture), cabinet, and a portable desk is light enough to be placed on a person's lap. Since many people lean on a desk while using it, a desk must be sturdy. In most cases, people sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lever
A lever is a simple machine consisting of a beam (structure), beam or rigid rod pivoted at a fixed hinge, or '':wikt:fulcrum, fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load, and effort, the lever is divided into Lever#Types of levers, three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English language, English around 1300 from . This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to , itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The word's primary origin is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear
A gear or gearwheel is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel. A cog may be one of those pegsDefinition of "cog" in the ''Oxford Learner's Dictionary'' online. Accessed on 2024-07-29.Definition of "cog" in the ''Merriam-Webster Dictionary'' online.

Wooton Desk
The Wooton desk is a variation of the fall front desk, native to Indianapolis, Indiana, and produced from 1874 to 1890. History Indianapolis, Indiana entrepreneur William S. Wooton obtained patents for his desk design in 1874. The desk was introduced at a time when the small business owner was seeing an increase in daily correspondence. With this increase in paperwork came the need for adequate storage and retrieval of files. An early advertisement for the Wooten desk described the model as follows: ''Everything that ingenuity can suggest or devise to facilitate desk labor, has been introduced in our secretary...Its comprehensive character is such that ample accommodations are afforded for the requirements of the most voluminous business. Every facility is furnished for a thorough and systematic classification of books, papers, memorandums, etc. Through its aid the usual fret and worry of office work is converted into a positive pleasure. It is a miniature counting-h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clock
A clock or chronometer is a device that measures and displays time. The clock is one of the oldest Invention, human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month, and the year. Devices operating on several physical processes have been used over the Millennium, millennia. Some predecessors to the modern clock may be considered "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology (the study of timekeeping), the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Turning
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a mechanism that can generate a variety of forms. The operator is known as a ''turner'', and the skills needed to use the tools were traditionally known as ''turnery''. In pre-industrial England, these skills were sufficiently difficult to be known as "the mysteries of the turners' guild." The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel posts for architecture; baseball bats, hollow forms such as w ...

Encyclopédie
, better known as ''Encyclopédie'' (), was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, and translations. It had many writers, known as the Encyclopédistes. It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert. The ''Encyclopédie'' is most famous for representing the thought of the Age of Enlightenment, Enlightenment. According to Denis Diderot in the article "Encyclopédie", the ''Encyclopédie'' aim was "to change the way people think" and for people to be able to inform themselves and to know things. He and the other contributors advocated for the secularization of learning away from the Jesuits. Diderot wanted to incorporate all of the world's knowledge into the ''Encyclopédie'' and hoped that the text could disseminate all this information to the public and future generations. Thus, it is an example of democratization of knowledge. It was also the first encyclopedia to include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Industrial Revolution
The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Kingdom of Great Britain, Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from craft production, hand production methods to machines; new Chemical industry, chemical manufacturing and Puddling (metallurgy), iron production processes; the increasing use of Hydropower, water power and Steam engine, steam power; the development of machine tools; and rise of the mechanisation, mechanised factory system. Output greatly increased, and the result was an unprecedented rise in population and population growth. The textile industry was the first to use modern production methods, and textiles b ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Secretary Desk
A secretary desk or escritoire is made of a base of wide drawers topped by a desk with a hinged desktop surface, which is in turn topped by a bookcase usually closed with a pair of doors, often made of glass. The whole is usually a single, tall and heavy piece of furniture. History Like the slant-top desk, the main work surface is a hinged piece of wood that is flat when open and oblique when raised to enclose secondary work surfaces such as small shelves, small drawers and nooks stacked in front of the user. Thus, like the Wooton desk, the fall-front desk and others with a hinged desktop, and unlike closable desks with an unmovable desktop like the rolltop desk or the cylinder desk, all documents and various items must be removed from the work surface before closing up. When closed, the secretary's desk looks like a cross between a commode-dresser, a slant-top desk and a bookcase. The secretary is one of the most common antique desk forms and has been endlessly reprod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
