Dewcar
The Dewcar was a British four-wheeled cyclecar made from 1913 to 1914 by D.E.W. Engineering Co Ltd of Eynsford, Kent. The car was designed by Harold E. Dew and was developed through a series of one-offs starting in 1910. The first production models were made in 1913 with single-seat bodies and used a single-cylinder Precision engine with a tax horsepower of 4.5. A two-seater was added shortly afterwards with a larger twin-cylinder engine with either air- or water-cooling. The single seater cost £75 and the two-seater £95 or £115 with the water-cooled option. D'Ultra cycle car (also D-Ultra and D.Ultra) Harold Dew left the company in February 1914 and set up a new concern at Charlotte Place, Clapham, London registered as D.U. Manufacturing Co making a car called the D'Ultra. This was available as either a two-seat car or delivery van and used a water-cooled Chater-Lea 8 hp 50-degree V-twin engine with 4-speed friction transmission. This transmission involved a prop-shaf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclecar
A cyclecar was a type of small, lightweight and inexpensive motorized car manufactured in Europe and the United States between 1910 and the early 1920s. The purpose of cyclecars was to fill a gap in the market between the motorcycle and the car. It could accommodate only two passengers, often sitting in tandem. The demise of cyclecars was due to larger cars – such as the Citroën Type C, Austin 7 and Morris Cowley – becoming more affordable. Small, inexpensive vehicles reappeared after World War II, and were known as microcars. Characteristics Cyclecars were propelled by engines with a single cylinder or V-twin configuration (or occasionally a three or four cylinder engine), which were often air-cooled. Sometimes motorcycle engines were used, in which case the motorcycle gearbox was also used. All cyclecars were required to have clutches and variable gears. This requirement could be fulfilled by even the simplest devices such as provision for slipping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eynsford
Eynsford ( or ) is a village and civil parish in the Sevenoaks District of Kent, England. It is located south east of Swanley, and south of Dartford, which is the village's postal town. Eynsford forms part of the London commuter belt. The village including its farmland and woods occupies the northern half of the triangle formed by three motorways in west Kent barring its very northernmost part which is Farningham. This area is undulating and has a large minority of woodland. In the south of the parish is Lullingstone, much of which was owned for many centuries by the large, late medieval Lullingstone Castle, whereas other parts of the village were owned by Eynsford Castle, which is older. Well before the founding of the Kingdom of England, Lullingstone Roman villa was founded in this part of the parish, which is open to the public today. The Darent Valley Path takes in a cross-section of the area. The village Eynsford is first mentioned in writing in 864, as "Egenes hom ...

Clapham
Clapham () is a district in south London, south west London, England, lying mostly within the London Borough of Lambeth, but with some areas (including Clapham Common) extending into the neighbouring London Borough of Wandsworth. History Early history The present day Clapham High Street is on the route of a Roman roads in Britannia, Roman road. The road is recorded on a Roman monumental stone found nearby. According to its inscription, the stone was erected by a man named Vitus Ticinius Ascanius. It is estimated to date from the 1st century AD. (The stone was discovered during building works at Clapham Common South Side in 1912. It is now placed by the entrance of the former Clapham Library, in the Old Town.) According to the history of the Clapham family, maintained by the College of Heralds, in 965 King Edgar of England gave a grant of land at Clapham to Jonas, son of the Duke of Lorraine, and Jonas was thenceforth known as Jonas "de [of] Clapham". The family remained in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chater-Lea
Chater-Lea was a British bicycle, car and motorcycle maker with a purpose-built five-storey factory in Banner Street, EC1, in the City of London (now converted into flats) and, from 1928, premises at Letchworth, Hertfordshire. It was founded by William Chater-Lea in 1890 to make bicycle frames and components. It made cars between 1907 and 1922 and motorcycles from 1903 to 1935. William died in 1927 and the business was taken over by his sons John and Bernard. After vehicle production finished, the company remained trading as a bicycle component maker and contract manufacturer until 1987. The company relaunched in 2017 as a maker of high-end British manufactured bicycle components and launched its first new products in the summer of 2019. History Bicycle and component production Founded by William Chater Lea in 1890 (the hyphenated name was adopted by the company in the 1920s for aesthetic reasons) the company produced Bicycles and components from their establishment in 1890 u ...

Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power (physics), power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion (mechanics), torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a Rotating spline, splined joint or prismatic joint.

Jackshaft
A jackshaft, also called a countershaft, is a common mechanical design component used to transfer or synchronize rotational force in a machine. A jackshaft is often just a short stub with supporting bearings on the ends and two pulleys, gears, or cranks attached to it. In general, a jackshaft is any shaft that is used as an intermediary transmitting power from a driving shaft to a driven shaft. History Jackshaft The oldest uses of the term ''jackshaft'' appear to involve shafts that were intermediate between water wheels or stationary steam engines and the line shafts of 19th century mills. In these early sources from New England mills in 1872 and 1880, the term ''"jack shaft"'' always appears in quotes. Another 1872 author wrote: "Gear wheels are used in England to transmit the power of the engine to what is usually called the jack shaft."Coleman Sellers, Transmission of MotionJournal of the Franklin Institute Vol. LXIV, No. 5 (Nov. 1872); pages 305-319, ''countershaft'' is ...

Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and analogue computers. Differentials can also provide a gear ratio between the input and output shafts (called the "axle ratio" or "diff ratio"). For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear. History Milestones in the design or use of differentials include: * 100 BCE–70 BCE: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by sponge divers, and modern research suggests that it used a differential gear to determine the angle between the ecliptic positions of the Sun and Moon, and thus the phase of the Moon. ...

Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rack And Pinion
rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert between rotational motion and linear motion: rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. The rack and pinion mechanism is used in rack railways, where the pinion mounted on a locomotive or a railroad car engages a rack usually placed between the rails, and helps to move the train up a steep gradient. It is also used in arbor presses and drill presses, where the pinion is connected to a lever and displaces a vertical rack (the ram). In pipelines and other industrial piping systems, a rack displaced by a linear actuator turns a pinion to open or close a valve. Stairlifts, lock gates, electric gates, and the mechanical steering mechanism of cars are other notable applications. The term "rack and pinion" may be used also when the rac ...
