Dragsaw
A dragsaw or drag saw is a large reciprocating saw using a long steel crosscut saw to buck logs to length. Prior to the popularization of the chainsaw during World War II, the dragsaw was a popular means of taking the hard work out of cutting wood. They would only work for a log on the ground. Dragsaws are known as the first mechanical saws to be used in the timber industry operation. These tools were most useful in the logging business, because they were efficient and very resilient. Not to be confused with a steam donkey. History Early dragsaws of the modern era were powered by levers or foot pedals, steam and later gasoline-powered. The post-modern steam-powered dragsaw was most commonly used in logging industry rather than merely clearing land due to its versatility. Many of the basic design principles from early dragsaws still apply to current products in the industry today. The inventor Robert G. Moores hypothesized that early non-mechanical versions of dragsaws may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chainsaw
A chainsaw (or chain saw) is a portable handheld power saw, power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, Log bucking, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of Wood fuel#Firewood, firewood, for use in Chainsaw carving, chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century. A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. History In surgery A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (–1785) by two Scot ...

Powerland Heritage Park
Powerland Heritage Park, formerly known as Antique Powerland, is a collection of museums and a self-described heritage site for power equipment, such as farm machinery, commercial trucks, trains, trolleys, construction equipment, logging equipment, and the engines which power them. It is located in Brooks, Oregon, United States (near Salem, Oregon), and is operated by the non-profit Antique Powerland Museum Association (APMA). It was initially established by a group of enthusiasts "dedicated to the preservation, restoration and demonstration of steam powered equipment, antique farm machinery and implements." The museum is located on a parcel of land just off Interstate 5 in Brooks, and has been in operation (in various forms) since the 1970s. Originally, the site was primarily used for "threshing bees", a forerunner to the modern tractor pull, and the remainder of the site committed to farming. With the addition of a truck museum and a railroad museum, the entire grounds were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treadle
A treadle (from , "to tread") is a foot-powered lever mechanism; it is operated by treading on it repeatedly. A treadle, unlike some other types of pedals, is not directly mounted on the crank (see treadle bicycle for a clear example). Most treadle machines convert reciprocating motion into rotating motion, using a mechanical linkage to indirectly connect one or two treadles to a crank. The treadle then turns the crank, which powers the machine. Other machines use treadles directly, to generate reciprocating motion. For instance, in a treadle loom, the reciprocating motion is used directly to lift and lower the harnesses or heddles; a common treadle pump uses the reciprocating motion to raise and lower pistons. Before the widespread availability of electric power, treadles were the most common way to power a range of machines. They are still widely used as a matter of preference and necessity. A human-powered machine gives the human operator close, instinctive control ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Fair
Live steam is steam under pressure, obtained by heating water in a boiler. The steam may be used to operate stationary or moving equipment. A live steam machine or device is one powered by steam, but the term is usually reserved for those that are replicas, scale models, toys, or otherwise used for heritage, museum, entertainment, or recreational purposes, to distinguish them from similar devices powered by electricity, internal combustion, or some other more convenient method but designed to look as if they are steam-powered. Revenue-earning steam-powered machines such as mainline and narrow gauge steam locomotives, full-sized steamships, and the worldwide electric power-generating industry steam turbines are not normally referred to as "live steam". Steamrollers and traction engines are popular, in 1:4 or 1:3 scale, as are model stationary steam engines, ranging from pocket-size to 1:2 scale. Railroads or railways Ridable, large-scale live steam railroading on a bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Montgomery Wards
Montgomery Ward is the name of two successive U.S. retail corporations. The original Montgomery Ward & Co. was a mail-order business and later a department store chain that operated between 1872 and 2001; its common nickname was "Monkey Wards". The current Montgomery Ward Inc. is an online shopping and mail-order catalog retailer that started several years after the original Montgomery Ward shut down. Original Montgomery Ward (1872–2001) Company origins Aaron Montgomery Ward started his business in Chicago; conflicting reports place his first office either in a single room at 825 North Clark Street or in a loft above a livery stable on Kinzie Street, between Rush and State Streets. In 1883, the company's catalog had grown to 240 pages and 10,000 items. In 1896, Ward encountered its first serious competition in the mail order business, when Richard Warren Sears introduced his first general catalog. In 1900, Ward had total sales of $8.7 million, compared to $10 million for Sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hit-and-miss Engine
A hit-and-miss engine or Hit 'N' Miss is a type of stationary internal combustion engine that is controlled by a governor to only fire at a set speed. They are usually 4-stroke, but 2-stroke versions were also made. It was conceived in the late 19th century and produced by various companies from the 1890s through approximately the 1940s. The name comes from the speed control on these engines: they fire ("hit") only when operating at or below a set speed, and cycle without firing ("miss") when they exceed their set speed. This is as compared to the "throttle-governed" method of speed control. The sound made when the engine is running without a load is a distinctive "Snort POP whoosh whoosh whoosh whoosh snort POP" as the engine fires and then coasts until the speed decreases and it fires again to maintain its average speed. The snorting is caused by the atmospheric intake valve used on many of these engines. Many engine manufacturers made hit-and-miss engines during their peak use ...

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Reciprocating Saw
A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall, is often used in the United States, where Milwaukee Electric Tool first produced a tool of this type in 1951. The noun "Sawzall" is commonly applied to a smaller type of battery-powered or line powered handheld saw used in construction and demolition work, as well as in gardening and the pruning of larger trees or plants. This type of saw, also known as a hognose, recip saw, or sawsaw, has a large blade, resembling that of a Jigsaw (power tool), jigsaw, and a handle oriented to allow the saw to be used comfortably on vertical surfaces. The typical design of this tool has a foot at the base of the blade, also similar to that of a jigsaw. The user holds or rests the foot on the surface being cut, thus countering the tendency of the blade to push-away from or p ...
