Nathaniel Batho (1802-1861)
of Barlow's Croft, Salford, and Manchester
Batho was described as a machine maker and tool maker. In the mid-19th century these terms generally applied to textile machinery and machine tool manufacture, respectively, but no specific reference has been found to him producing textile machinery. No surviving machine tools have been identified, but it seems likely that Batho was in the upper echelon of machine tool makers, judging by the company his machines kept (auction sale notices of machine shops often included machines by Batho with those from the likes of Sharp, Roberts, Collier, Fox, etc.).
'Mr. N. Batho, of Manchester, has also added a slotting apparatus to his patent lathes. We attached the following confused, and by no means intelligible description from the specification of Mr. Batho's patent. ....' See 1843 source for description
