The Durnford Regulator was an invention by an ancestor of Adrian
Taylor
to whom I am indebted for the following information and his permission to reproduce
it here.
"Fanny Maria Durnford married James Nash, cabinet maker, on 18/2/1877 at St John the Baptist Church, Hoxton. The Durnford address at this time was 16, Flemming Street. James father, also James, was an egg merchant. He was the supplier of the Durnfords Regulator. This was a machine that regulated the temperature for egg incubation. Trade leaflets describing the Regulator still exist and the Regulator was sold right across the country. It is believed to have been invented by Joseph Durnford."
