Cecil Wood (engineer)
Cecil Walkden Wood (1874 – 1965) was a New Zealand engineer from Timaru who made New Zealand's first motorcycle in 1901 and second known indigenous motor car in 1902. He also instructed Richard Pearse on making an engine for his flying machine in 1901 and 1902. Early life Wood was born in Timaru on 28 March 1874, the son of Charles Walkden Wood. Educated in Lyttelton, he first worked as a mechanical engineer at Lyttelton, and then became involved in the cycle trade in Christchurch. He married Edith Susan Harris, a daughter of Thomas Harris of Timaru, in September 1899, and they had one son. Tourist Cycle Works, C. W. Wood and Co. Cecil Wood and James Gibson opened their Timaru cycle business, Gibson, Wood and Co., on 8 April 1894; the first cycle shop in town. Charles Macintosh and John James Grandi, coachbuilder, soon joined the partnership. Wood carried on the firm as Tourist Cycle Works, C. W. Wood and Co., when Gibson left the partnership to establish Reliance Cycle Works ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tricycle
A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor powered or assisted, or gravity powered) three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children and senior adults for their apparent stability versus a bicycle; however a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over. Unconventional designs such as recumbents have a lower centre of gravity so require less care. History A three-wheeled wheelchair was built in 1655 or 1680 by a disabled German man, Stephan Farffler, who wanted to be able to maintain his mobility. A watch-maker, Farffler created a vehicle that was powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulky
A sulky is a lightweight cart with two wheels and a seat for the driver, generally pulled by horses or dogs. With horses, a sulky is used for harness racing. The term is also used for an arch-mounted cart on wheels or crawler tracks, used in logging, or other types of vehicle having wheels and usually a seat for the driver, such as a plough, lister or cultivator. Horse sulky A sulky for horses is a lightweight two-wheeled, single-seat cart that is used as a form of rural transport in many parts of the world. A special development of this is now used in most forms of harness racing in Argentina, Australia, Canada, France, the United States and New Zealand, including both trotting and pacing races. They are reputedly called "sulkies" because the driver must prefer to be alone."The Encyclopaedia of Driving" 1979, by Sallie Walrond Race sulkies come in two categories, * Traditional symmetrical sulkies * Asymmetric or "offset" sulkies An "improved sulky" with pneumatic tire ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Electrode
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Anode and cathode in electrochemical cells Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell. This battery consisted of a stack of copper and zinc electrodes separated by brine-soaked paper disks. Due to fluctuation in the voltage provided by the voltaic cell it wasn't very practical. The first practical battery was invented in 1839 and named the Daniell cell after John Frederic Daniell. Still making use of the zinc–copper electrode combination. Since then many more batteries have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''side ...

George Bolt
George Bruce Bolt (24 May 1893 – 27 July 1963) was a pioneering New Zealand aviator. Biography Bolt was born in Dunedin in 1893. He formed the Canterbury Aero Club in 1910, helping to make and fly gliders on the Cashmere Hills. He used these to take aerial photographs in 1912. In 1916 Bolt was hired by pioneer pilot Vivian Walsh as a mechanic at the Walsh Brothers Flying School at Kohimarama. He learnt to fly the brothers' Curtiss flying boats and the machines of their own design, including the Walsh brothers Type D, as well as the two Boeing and Westervelt floatplanes which were the first machines made by that company. In 1919 he flew New Zealand's first air mail and established an altitude record of .Rendel, David (1975) ''Civil Aviation in New Zealand: An Illustrated History''. Wellington. A.H. & A.W.Reed.

Motorized Tricycle
A motorized tricycle, motor trike, or motortrycle is a three-wheeled vehicle based on the same technology as a bicycle or motorcycle, and powered by an electric motor, motorcycle engine, motorcycle, scooter or car engine. Classification Depending on the design of the vehicle, a motorized trike may be categorized as a motorcycle, motor scooter, or simply the three-wheeled counterpart to a Motorized bicycle, motorized or electric bicycle. The main difference between a motorcycle trike and a scooter trike is that motorcycles are sat on in a "saddle"-style seating (as with a horse), with the legs apart, and motorcycles have manual transmissions. Scooters have a "step-through" seating style, in which the driver sits on a more chair-like seat, with the legs together; as well, scooters have automatic transmissions. Laypersons often associate the engine size as a dividing line between motorcycles and scooters, since a typical scooter has a small 50 cc engine, but scooter engines can als ...

Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kayaks wh ...
