Manual Vacuum Cleaners
The manual vacuum cleaner was a type of non-electric vacuum cleaner, using suction to remove dirt from carpets, being powered by human muscle, similar in use to a manual lawn mower. Its invention is dated to the second half of the 19th century, when patents were granted to inventors in the United States, Britain, France, and elsewhere. Mechanics These household appliances created suction by either a pumping action, bellows, a piston being pushed up and down a tube, or had a fan driven by the wheels. Most required the efforts of two people. The models operable by one person were less efficient, but none were truly labor-saving devices or delivered the cleaning efficiency they promised. Besides hand-operated models, foot-operated models were also available, and according to a Swiss source there was even one where the operator sat in a rocking chair, rocking back and forth to produce the energy needed to create suction.

Vacuum Cleaner
A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove dirt from floors, upholstery, draperies, and other surfaces. It is generally electrically driven. The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dirt before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both solid matter and liquids. Name Although ''vacuum cleaner'' and the short form ''vacuum'' are neutral names, in some countries (UK, Ireland) ''hoover'' is used instead as a genericized trademark, and as a verb. The name comes from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suction
Suction is the colloquial term to describe the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment. Suctions can form on the sea, for example, when a ship founders. When the pressure in one part of a physical system is reduced relative to another, the fluid in the higher pressure region will exert a force relative to the region of lowered pressure, referred to as pressure-gradient force. Pressure reduction may be static, as in a piston and cylinder arrangement, or dynamic, as in the case of a vacuum cleaner when air flow results in a reduced pressure region. When animals breathe, the diaphragm and muscles around the rib cage cause a change of volume in the lungs. The increased volume of the chest cavity decreases the pressure inside, creating an imbalance with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpet
A carpet is a textile floor covering typically consisting of an upper layer of pile attached to a backing. The pile was traditionally made from wool, but since the 20th century synthetic fibers such as polypropylene, nylon, or polyester have often been used, as these fibers are less expensive than wool. The pile usually consists of twisted tufts that are typically heat-treated to maintain their structure. The term ''carpet'' is often used in a similar context to the term ''rug'', but rugs are typically considered to be smaller than a room and not attached to the floor. Carpets are used for a variety of purposes, including insulating a person's feet from a cold tile or concrete floor, making a room more comfortable as a place to sit on the floor (e.g., when playing with children or as a prayer rug), reducing sound from walking (particularly in apartment buildings), and adding decoration or color to a room. Carpets can be made in any color by using differently dyed fibers. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawn Mower
A lawn mower (also known as a mower, grass cutter or lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small (typically one cylinder) internal combustion engine. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major Appliance
A major appliance, also known as a large domestic appliance or large electric appliance or simply a large appliance, large domestic, or large electric, is a non-portable or semi-portable machine used for routine housekeeping tasks such as cooking, washing laundry, or food preservation. Such appliances are sometimes collectively known as white goods, as the products were traditionally white in colour, although a variety of colours are now available. An appliance is different from a plumbing fixture because it uses electricity or fuel. Major appliances differ from small appliances because they are bigger and not portable. They are often considered Fixture (property law), fixtures and part of real estate and as such they are often supplied to tenants as part of otherwise unfurnished rental properties. Major appliances may have special electrical connections, connections to gas supplies, or special plumbing and ventilation arrangements that may be permanently connected to the applia ...

Baby Daisy - Edwardian Vacuum Cleaner
An infant or baby is the very young offspring of human beings. ''Infant'' (from the Latin word ''infans'', meaning 'unable to speak' or 'speechless') is a formal or specialised synonym for the common term ''baby''. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In medical contexts, a newborn or neonate (from Latin, ''neonatus'', newborn) is an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants. Before birth, the offspring is called a fetus. The term ''infant'' is typically applied to very young children under one year of age; however, definitions may vary and may include children up to two years of age. When a human child learns to walk, they are called a toddler instead. Other uses In British English, an ''infant school'' is for children aged between four and seven. As a legal term, ''infancy'' is more lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sears
Sears, Roebuck and Co. ( ), commonly known as Sears, is an American chain of department stores founded in 1892 by Richard Warren Sears and Alvah Curtis Roebuck and reincorporated in 1906 by Richard Sears and Julius Rosenwald, with what began as a mail ordering catalog company migrating to opening retail locations in 1925, the first in Chicago. In 2005, the company was bought by the management of the American big box discount chain Kmart, which upon completion of the merger, formed Sears Holdings. Through the 1980s, Sears was the largest retailer in the United States. In 2018, it was the 31st-largest. After several years of declining sales, Sears's parent company filed for Chapter 11 bankruptcy on October 15, 2018. It announced on January 16, 2019, that it had won its bankruptcy auction, and that a reduced number of 425 stores would remain open, including 223 Sears stores.

Rural Electrification Act
The Rural Electrification Act of 1936, enacted on May 20, 1936, provided federal loans for the installation of electrical distribution systems to serve isolated rural areas of the United States. The funding was channeled through cooperative electric power companies, hundreds of which still exist today. These member-owned cooperatives purchased power on a wholesale basis and distributed it using their own network of transmission and distribution lines. The Rural Electrification Act was one of many New Deal proposals by President Franklin D. Roosevelt to remedy high unemployment during the Great Depression. History On May 11, 1935, President Roosevelt issued Executive Order 7037, which created the Rural Electrification Administration. In 1936, the Congress endorsed Roosevelt's action by passing the Rural Electrification Act. At the time the Rural Electrification Act was passed, electricity was commonplace in cities but largely unavailable in farms, ranches, and other rural places ...

WW1 Hoover 0212-6
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Friction Motor
A friction motor is a simple mechanism to propel toy cars, trucks, trains, action figures and similar toys. The motor consists of a large flywheel which is connected to the drive wheels of the toy via a very low gear ratio, so that the flywheel revolves faster. The flywheel's axis is perpendicular to the direction in which the toy faces and moves. When the toy is pushed forward, the drive wheels engage the flywheel. Pushing the vehicle forward repeatedly spins this flywheel up to speed. When let go, the flywheel drives the vehicle forward. The flywheel stores the kinetic energy of the initial acceleration and propels the toy after it is released, by forcing the perpetual motor that revolves the kinetic energy. As the flywheel, unlike the spring of a pullback motor A pullback motor (also ''pull back'' or ''pull-back'') is a simple clockwork motor used in toy cars. A patent for them was granted to Bertrand 'Fred' Francis in 1952 as a keyless clockwork motor. Pulling the car ''ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
