John Ramsbottom (engineer)
John Ramsbottom (11 September 1814 – 20 May 1897) was an English mechanical engineer. Born in Todmorden, then on the county border of Yorkshire and Lancashire. Ramsbottom was the son of a steam cotton mill owner. He learned about steam engines, rebuilding his father's and also invented the weft fork (this has also been attributed to James Bullough) that enabled looms to be run at high speed. He also created many inventions for railways but his main legacy is the split metal piston ring, which he invented and later perfected. Virtually all reciprocating engines continue to use these today. Career In 1839 Ramsbottom joined Sharp, Roberts and Company of Manchester who made both industrial stationary engines and steam locomotives, and learned of the latter. He was recommended by Charles Beyer in 1842 to become locomotive superintendent of the Manchester and Birmingham Railway (M&BR). In 1846 the M&BR merged and became the London and North Western Railway (LNWR), and Ramsb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Percy (portrait Artist)
William Percy (1820–1903) was a portrait artist of Manchester, England. He was born in Chorlton-on-Medlock in 1820. His love of art began early in his life: his first picture was exhibited at the Manchester Autumn Festival in 1833. In 1836 he went to London to become a pupil and assistant of William Bradley. He returned to Manchester early in 1839 where he established a first class reputation as a portrait painter. Percy was a founder of the Manchester Academy of Art in 1845. As he wrote later: First - to institute a class for the study of the antique and the living model - the want of which has been long felt by the students and artists of this town as an insuperable bar to professional advancement. Secondly - to collect a library for reference, comprising history, poetry, archeology, optics, anatomy, chemistry, as applied to colour, architecture, sculpture, painting and engraving. In 1882, Percy's painting of poet Edwin Waugh was hung at the Manchester Art Gallery. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rugby, Warwickshire
Rugby is a market town in eastern Warwickshire, England, close to the River Avon. In the 2021 census its population was 78,125, making it the second-largest town in Warwickshire. It is the main settlement within the larger Borough of Rugby which has a population of 114,400 (2021). Rugby is situated on the eastern edge of Warwickshire, near to the borders with Leicestershire and Northamptonshire. Rugby is the most easterly town within the West Midlands region, with the nearby county borders also marking the regional boundary with the East Midlands. It is north of London, east-southeast of Birmingham, east of Coventry, north-west of Northampton, and south-southwest of Leicester. Rugby became a market town in 1255, but remained a small and fairly unimportant town until the 19th century. In 1567 Rugby School was founded as a grammar school for local boys, but by the 18th century it had gained a national reputation as a public school. The school is the birthplace of Rugby foo ...

Displacement Lubricator
An automatic lubricator is a device fitted to a steam engine to supply lubricating oil to the cylinders and, sometimes, the bearings and axle box mountings as well. There are various types of automatic lubricator, which include various designs of displacement, hydrostatic and mechanical lubricators. Displacement lubricator Ramsbottom type The displacement lubricator was introduced in the United Kingdom in 1860 by John Ramsbottom. It operates by allowing steam to enter a closed vessel containing oil. After condensing, the water sinks to the bottom of the vessel, causing the oil to rise and overflow into delivery pipes. The oil from the delivery pipes is introduced into the steam pipe, where it is atomised and carried to the valves and cylinders. In early applications in steam locomotives, either two displacement lubricators (one for each cylinder) would be positioned at the front of the boiler near the valves, often on either side of the smokebox or one lubricator would be ...

Safety Valve
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk. Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early boilers operating without them were prone to explosion unless carefully operated. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manu ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

LNWR Special Tank
The London and North Western Railway (LNWR) Special Tank was a class of steam locomotives. They were a saddle tank version of the LNWR DX Goods class. A total of 278 locomotives were built from 1870 onwards, of which five survived to be inherited by British Railways in 1948. These five were in departmental stock: four – numbered 3 (né 317), 6, 7 (2329) and 8 ''Earlstown'' (2359) – as Carriage Department shunters at Wolverton Works; and No. 3323 (né 2322 May 1878), a shunter at Crewe Works Crewe Works is a British railway engineering facility located in the town of Crewe, Cheshire. The works, which was originally opened by the Grand Junction Railway in 1840, employed around 7,000 to 8,000 workers at its peak. In the 1980s, a lot ....

LNWR Newton Class
The LNWR ''Newton'' Class was a class of ninety-six steam locomotives built by the London and North Western Railway at their Crewe Works between 1866 and 1873. They were officially designated Curved Link 6-ft 6-in Passenger due to the use of a curved link between the fore and back eccentric rods of their Stephenson valve gear and the use of diameter wheel centres, which, together with thick tyres gave a driving wheel diameter of . They were designed by John Ramsbottom who had 76 built, all without cabs and with pierced driving wheel splashers. Ramsbottom's successor F. W. Webb Francis William Webb (21 May 1836 – 4 June 1906) was an English railway engineer, responsible for the design and manufacture of locomotives for the London and North Western Railway (LNWR). Webb was born in Tixall Rectory, near Stafford, th ..., built twenty more, all with cabs. The earlier locomotives also gained cabs, and all eventually had the splashers filled in.

LNWR Samson Class
The LNWR ''Samson'' Class was a class of ninety steam locomotives built by the London and North Western Railway at their Crewe Works between 1863 and 1879. They were officially designated Curved Link 6-ft Passenger due to the use of Stephenson valve gear which included a curved expansion link between the fore and back eccentric rods (earlier LNWR designs had used the Allan valve gear which had a straight expansion link) and the use of diameter wheel centres, which, together with thick tyres gave a driving wheel diameter of . Ostensibly a mixed traffic design, they were the first locomotives with coupled driving wheels to be allocated for passenger duties on the LNWR. They were designed by John Ramsbottom who had fifty built, all without cabs and with pierced driving wheel splashers. Ramsbottom's successor F. W. Webb, built forty more, all with cabs. The earlier locomotives also gained cabs, and all eventually had their splashers filled in. All ninety locomotives were 'ren ...

LNWR 4ft Shunter
The London and North Western Railway (LNWR) 4ft Shunter was a class of 0-4-0ST steam locomotives. Introduced in 1863 by Ramsbottom, 26 were built in 1863–1865, 10 in 1870, 10 in 1872, and 10 in 1892. The last three of the latter batch were soon rebuilt as 0-4-2ST crane tanks. They survived into LMS ownership in 1923 and the last one was withdrawn in 1933. Unusually they were fitted with launch-type boilers. These have a cylindrical furnace, rather than a conventional locomotive firebox. This limits the grate area and ashpan size, although this is not a limitation for short-ranged shunters. One advantage is that the ashpan does not project downwards, making it possible to place the rear axle further back. For a dock shunter operating on tight radius curves this is useful, as it reduces the rear overhang and so the amount by which the coupling and buffers swing sideways on curves. Preservation One example survives in the NRM collection, kept at the Ribble Steam Railway. 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LNWR Problem Class
The London and North Western Railway (LNWR) 7 ft 6 in Single 2-2-2 class was a type of express passenger locomotive designed by John Ramsbottom. The class is better known as the Problem class for the first locomotive built, or the Lady of the Lake class for the example that was displayed at the International Exhibition of 1862. The first examples were built shortly after the acquisition of the Chester and Holyhead Railway by the LNWR, and primarily saw use on the Irish Mail route from London to Holyhead. They were the first locomotives to be fitted with water scoops, which could refill the tender from water troughs between the tracks without stopping. One such locomotive, No. 229 ''Watt'', was the first to use them in non-stop run from Holyhead to Stafford in 1862, while conveying despatches relating to the Trent Affair. Design The ''Lady of the Lake'' class was the second type of locomotive designed by Ramsbottom. It was typical of express passenger locomotives ...

LNWR DX Goods Class
The London and North Western Railway (LNWR) DX Goods class was a class of 0-6-0 steam locomotive, designed by John Ramsbottom for freight duties. 943 were constructed making them the largest single class of steam locomotives built in the United Kingdom. Despite this, none were preserved. History The "DX" goods engine was the first original design produced by Ramsbottom, shortly after becoming Locomotive Superintendent of the Northern Division. An experimental prototype was developed at Longsight whilst Ramsbottom was only in charge of the North-Eastern Division. The first regular example was completed at Crewe Works in September 1858, and was given the running number 355. This was the 399th locomotive built at Crewe, but it was the practice of the LNWR to reuse the numbers of withdrawn locomotives. The first DX, No. 355, was named ''Hardman'', and carried the name on a curved brass plate above the driving wheels. It was painted in the same dark green livery as used by Ramsbott ...
