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. He was the Chief Mechanical Engineer for the London and North Western Railway for 14 years. He created many inventions for railways but his main legacy is the split metal piston ring, virtually all reciprocating engines continue to use these today.

Early life
John Ramsbottom was born on 11 September 1814 in Todmorden. He was the third child of six and the youngest son. His parents were Henry and Sarah Ramsbottom, Henry was a cotton spinner. His grandfather was John Ramsbottom, a tailor.

He had little in the way of schooling having "a short time spent in a dame's school he went to four schoolmasters in succession, then to a baptist minister, then to a colleague of the latter, who taught him as far as simple equations".

Todmorden
His grandfather and father leased land in the Salford area of Todmorden, and in 1804-1805 established the "Steam Factory", the first steam powered cotton spinning mill in Todmorden.

His father gave him a lathe which he used to construct models of various steam engines for his own education and to entertain friends. He used these skills in the workplace rebuilding and modifying the mill engine. He was interested in other technologies, installing the 'new' coal gas illumination in the mill and manufacturing a machine to produce cut nails. In partnership with his uncle, Richard Holt, he took out a patent (No. 6644) in 1834 for an improvement to a power loom, described in Pennie (2007) as a "vertical loom and weft-fork". In 1836 he took out another patent (No. 6975) for "roving, spinning and doubling of fibres".

Manchester
In 1839 he went as a journeyman to Sharp, Roberts & Co. in Manchester. The company manufactured textile machinery and machine tools at their Atlas Works in Manchester. By the time Ramsbottom joined them they were also a successful manufacturer of steam locomotives and here he "gained practical knowledge of the design and construction of steam locomotives".

Three years later, in May 1842, on the recommendation of Charles Beyer (later to become co-founder of Beyer, Peacock and Company in 1854) Ramsbottom was appointed locomotive superintendent of the newly opened Manchester and Birmingham Railway (M&BR) at their new works at Longsight, Manchester. In November 1843 he was promoted to take charge of the newly formed locomotive and rolling stock department when the M&BR separated their civil and mechanical engineering departments, at a salary of £170.

In 1846 the M&BR merged and became part of the London and North Western Railway (L&NWR), and Ramsbottom became District Superintendent North Eastern Division, remaining at Longsight at an increased salary of £300.

Crewe
In 1857 the North and North Eastern divisions of the L&NWR were amalgamated into the Northern Division (lines north of Rugby), Ramsbottom became Northern locomotive superintendent, based at Crewe Works.

In 1862 the L&NWR Northern and Southern divisions were amalgamated with Ramsbottom becoming Chief Mechanical Engineer (CME) for the whole system. Shortly after a Bessemer Steel Works was authorised for installation at Crewe so that the L&NWR could produce its own steel for locomotive construction and rails.

During his time as CME he oversaw the enlargement and modernisation of Crewe works, he was responsible for the bulk production of cheap but capable locomotives, introduced ancillary works including the steel plant and a brickworks, and installed an internal narrow-gauge railway to facilitate the movement of material.

Post L&NWR
Ramsbottom retired in 1871 ostensibly because of ill health but likely because his request for a salary increase was turned down by the L&NWR Board of Directors. The L&NWR continued to pay Ramsbottom an annual stipend of £1,000 for several years after he left, valuing his expertise as a consultant if not as an employee.

However, in 1883 Ramsbottom became a consulting engineer and a director of the Lancashire and Yorkshire Railway (L&YR), where his major legacy was the establishment of Horwich Works on a greenfield site near Bolton.

Locomotive designs 

During his time at Crewe he was responsible for the design and production of the following locomotives;

L&NWR 2-2-2 Cornwall, rebuilt to his design in 1858
L&NWR DX Goods class 0-6-0
L&NWR Lady of the Lake Class 2-2-2
L&NWR 4ft Shunter 0-4-0ST
L&NWR Samson Class 2-4-0
L&NWR Newton Class 2-4-0
L&NWR Special Tank 0-6-0ST

He laid the foundation for the L&NWR engine design by adopting inside frames, his safety valves, screw reversing gear and left-hand drive.

Innovations

Ramsbottom applied for 24 patents between 1834 and 1880 of which 23 were approved, they are listed below:

1834 -In partnership with his uncle, Richard Holt, he took out patent No. 6644 for an improvement to a power loom, described in Pennie (2007) as a "Vertical loom and weft-fork".

Appointments
He was president of the Crewe Mechanics Institute from 1857 to 1871. He was a founder member of the Institution of Mechanical Engineers in 1847 and became its president in 1870-71. Ramsbottom became a member of the Institution of Civil Engineers in 1866.

Ramsbottom was appointed a life governor of Owens College in Manchester (now the University of Manchester) where he assisted in expanding the mechanical engineering department. His interest in the College was such that he established a scholarship, tenable for two years to be competed for by young men employed in the locomotive department of the L&NWR.
He was a director of Beyer-Peacock from 1885 where his two sons John and George held positions. He took up a directorship in the L&YR in 1885 after working as a consultant for them on their new locomotive works.
In 1890 he received an honorary degree of Master of Engineering from Dublin University.

Family
He married Mary Peckett, the eldest daughter of William Peckett, a Quaker linen manufacturer of Barnsley on 29 April 1851. They lived near Longsight depot where Ramsbottom was based at the time, their son William Henry was born here on 28 February 1852.

Shortly after he moved to Crewe in 1857 his wife, who was still at Longsight, died of "venous congestion of the lungs".

He married again on 12 April 1859 to Mary Anne Goodfellow and they had a son, John Goodfellow, in 1860, daughters Margaret Holt in 1861, Jane in 1863, Mary Edith in 1865, a son George Holt in 1868, daughters Eliza in 1874 and Hannah Mary in 1878. Margaret and Eliza died as children.
