1853 Patent No. 1502 was granted to Hiram Barker of Manchester, Engineer and Tool Maker, and Francis Holt of Manchester, Engineer, for improvements in machinery and apparatus for grinding and turning metals. L. T. C. Rolt states that this was the first machine made for grinding metal balls [4]. Details (in German) here. The description gives an example of six 2" cast brass balls being 'ground sufficiently round in 6 to 7 hours to be used as valves for locomotive pumps'.

1893 Obituary [7]
FRANCIS HOLT was born at Todmorden on 5th December 1825.
After serving his apprenticeship with Messrs. Sharp Stewart and Co., Manchester, he remained with them for some time as foreman, and went thence to Woolwich dockyard.
Afterwards he was engaged in Italy on the construction of a railway at Pisa; but in consequence of the stoppage of that undertaking he returned to England, and had charge for about a year and a half of the locomotive department of the South Staffordshire Railway at Walsall.
He next went out to India, to erect and fit up a cotton mill for the Oriental Spinning and Weaving Co., Bombay, and remained there three years.
Returning to this country he became manager for some years at Messrs. Beyer Peacock and Co.'s locomotive works, Gorton, Manchester; and then manager to Messrs. R. and W. Hawthorn, Newcastle-on-Tyne.
In 1874 he left there to undertake the managership of the Midland Railway locomotive works at Derby, where he remained up to the time of his death. During his connection with these works they underwent large extensions, in which he took a prominent part.
He was well known in the railway and engineering world as a man of large and varied experience, and of indomitable perseverance in whatever he undertook.
He invented an arrangement of pipe connections between locomotive engines and tenders for water, steam, and air; and also a plan for securing and finishing the eccentrics on the crank-shafts of locomotive and other engines. He was also concerned in a method of applying sand for preventing the driving wheels of locomotives from slipping.
His death took place at Spondon, near Derby, on 7th January 1893, at the age of sixty-seven.
He became a Member of this Institution in 1863.
