John Oldham (engineer)
John Oldham (1779–1840) was an Irish people, Irish engineer, now best known for the Oldham coupler. Life Born in Dublin, Oldham was apprenticed to an engraver there, but then became a miniature-painter. He invented a numbering machine, which in 1809 he unsuccessfully offered to the bank of Newry for numbering their banknotes. In 1812 the machine was adopted by the Bank of Ireland, and he received the appointment of engineer and chief engraver. In 1837 Oldham entered the service of the Bank of England, where he introduced improvements in the machinery for printing and numbering banknotes. This machinery continued in use until 1852–3, when the system of surface-printing was adopted. He died at his house in Montagu Street, Russell Square, London, on 14 February 1840. Engineer Oldham also paid attention to marine propulsion, and in 1817 he obtained a patent (No. 4169) for propelling ships by means of paddles worked by a steam-engine, an attempt to imitate the motion of a paddle ...

Irish People
The Irish ( ga, Muintir na hÉireann or ''Na hÉireannaigh'') are an ethnic group and nation native to the island of Ireland, who share a common history and culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also conquered parts of Ireland in the 12th century, while England's 16th/17th century conquest and colonisation of Ireland brought many English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Ireland) and Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities including British, Irish, Northern Irish or som ...

Oldham Coupler
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. Uses Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfer power to pump through coupling). Other common uses: * To alter the vibration characteristics of rotating units * To connect the driving and the driven ...
